“METHODS FOR DYNAMICALLY DESIGNING OPERATORS TO REMOTE CONTROL AND / OR MONITOR MOVEMENTS OF ONE OR MORE VEHICLE SYSTEMS AND REMOTE OPERATOR DESIGNATION SYSTEM”
Cross Reference to Related Orders [001] This order is partly a continuation of US Patent Application No. 15 / 460,431, which was filed on March 16, 2017, and which claims priority for US Provisional Application No. 62 / 327,101 , which was filed on April 25, 2016. This application is also part of a continuation of US Patent Application No. 15 / 402,797, which was filed on January 10, 2017. All disclosures for these three patent applications are here incorporated by reference.
Field of Invention [002] The subject matter described here refers to remotely controlled vehicles.
Background of the Invention [003] Many transportation segments are looking at remote vehicle operations. For example, the auto industry, the truck industry, the railway industry, etc., are moving towards the remote control, at least partially, of vehicles such as automobiles, trucks, trains or the like. While some industries may be looking at autonomous vehicles, those same industries may be looking at a backup solution where an operator located remotely is able to take control of a vehicle from afar (for example, due to a system failure or other problem with the autonomous characteristics of the vehicle).
[004] Remote operators can be assigned to remotely control vehicles based on a variety of
Petition 870190039552, of 04/26/2019, p. 170/339
2/136 designation. Many of these known designation processes, however, are rooted in an analysis of characteristics or static risks for remote vehicle operation. These characteristics or static risks may include known risks that do not change over time. But vehicle movement and vehicle remote control can encounter risks that change dynamically over time. These time-varying risks may not be addressed by the currently known operator designation processes.
Description of the Invention [005] In one embodiment, a method includes determining time-varying risk profiles for multiple separate vehicle systems that are remotely controlled by operators that are located outside the separate vehicle systems. Time-varying risk profiles represent one or more risks to the path of separate vehicle systems during trips of separate vehicle systems that change with respect to time during trips of separate vehicle systems. The method also optionally includes determining a demand for operator personnel for vehicle systems based on the time-varying risk profiles of separate vehicle systems. Demand for operator personnel represents how many of the operators are required to remotely control separate vehicle systems at different times during travel and a required qualification of one or more operators to remotely control separate vehicle systems at different times during travel . The method also includes designating operators to remotely monitor or control separate vehicle systems while traveling, based on time-varying risk profiles. Optionally, this designation can also be based on the demand for operator personnel. THE

3/136 operator assigned to one or more of the separate vehicle systems changes over time during the travel of one or more separate vehicle systems, while the one or more separate vehicle systems are moving along one or more routes during the trip.
[006] In one embodiment, a system includes one or more processors configured to determine time-varying risk profiles for multiple separate vehicle systems that are remotely controlled by operators that are located outside the separate vehicle systems. Time-varying risk profiles represent one or more risks to the path of separate vehicle systems during trips of separate vehicle systems that change with respect to time during trips of separate vehicle systems. The one or more processors are also configured to designate operators to remotely monitor or control separate vehicle systems while traveling, based on time-varying risk profiles. The operator assigned to one or more of the separate vehicle systems changes over time during the journey of the one or more separate vehicle systems, while the one or more separate vehicle systems are moving along one or more routes during the travel.
[007] In one embodiment, a method includes determining a time-varying risk profile for a vehicle system that must be one or more remotely controlled or remotely monitored by one or more operators that are located outside the system of vehicle, and the determination of a demand for operator personnel for the vehicle system based on the time-varying risk profile that is determined. The demand for operator personnel represents how many of the operators are required for one or more of them to remotely control or remotely monitor the vehicle system. The method
Petition 870190039552, of 04/26/2019, p. 172/339
4/136 also includes designating at least one of the operators to remotely monitor or control the vehicle system based on the demand for operator personnel and the time-varying risk profile. The at least one operator assigned to the vehicle system changes over time over the course of the vehicle system.

Description of Realizations of the Invention [009] The subject matter described herein refers to remote operator designation systems and methods that examine static and dynamic risks of switching to remote vehicle control, operator qualifications, operator availability and the like, and dynamically designate which operators remotely control or monitor the movement of vehicle systems. An operator can remotely control a vehicle when the operator is located outside the vehicle and controls the movements of the
Petition 870190039552, of 04/26/2019, p. 175/339
7/136 vehicle from afar. In one embodiment, the remote control of vehicle systems, as described herein, refers to the remote control of automobiles, railway vehicles, marine vessels and the like, and does not extend to the remote control of toy or model vehicles (for example, model trains, model cars, model airplanes, remote control toy boats, etc.). One embodiment of the inventive object material described here relates to the designation of operators to remotely control aircraft, such as drones or other aircraft.
[010] At least one embodiment described in this document provides a system and method of designation that determine time-varying risk profiles for each vehicle of the various vehicle systems that travel within a monitored transport system. The monitored transport system can be part or all of a network of interconnected routes, such as interconnected roads, rails, channels, etc., which is monitored by sensors so that operators can remotely control the movement of vehicle systems on routes . Risk profiles can quantify the amount of risk involved in the remote control of a vehicle. As described here, there may be a greater risk (and a higher numerical value assigned to the risk profile) in a vehicle carrying dangerous cargo, a vehicle traveling through a congested area, a vehicle traveling through dangerous weather conditions, or the like, compared to other vehicle systems. The risk can change over time, so a vehicle's risk profile can change over time. The risk can be estimated based on predicted or predicted conditions (for example, weather conditions, traffic conditions, etc.).
[011] The system and method can use the risk profiles of vehicle systems to determine the needs of operator personnel
Petition 870190039552, of 04/26/2019, p. 176/339
8/136 for vehicle systems over time. The needs of operator personnel can indicate how many operators are needed at different times to remotely control vehicle systems (for which risk profiles have been determined) and, optionally, can indicate specialized operator qualifications that are required in one or more times to remotely control vehicle systems. Specialized qualifications can be years of operator experience, training classes or sessions completed by the operator, types of licenses obtained by operators, etc. The qualifications that are required can change over time. For example, as a remotely controlled vehicle travels across different geographic areas, the risks involved in remote vehicle control in some areas may increase significantly (thus potentially requiring specialized operator training) or decrease (thereby potentially eliminating need for specialized operator training). As another example, as a remotely controlled vehicle travels through different jurisdictions, different laws and / or regulations may require different operator qualifications for travel in the corresponding areas. The system and method can optionally determine the need for operator personnel based on the likelihood of vehicle failure or other emergency situations. This probability can be determined or, otherwise, based on previous routes of the vehicle systems in the transport system and can increase for higher risk profiles (or decrease for lower risk profiles).
[012] The system and method can use the needs of operator personnel to determine the levels of operator personnel. Operator personnel levels can be a number of operators required to be available (for example, in a facility from
Petition 870190039552, of 04/26/2019, p. 177/339
9/136 which vehicle systems are controlled remotely) at different future times (for example, during a next work shift). Operator personnel levels can also indicate the number of operators required to be available for a future shift that has a specialized qualification, as described above. The system and method can then use personnel operators to remotely control the movements of vehicle systems during movement in the transport system. The system and method can select operators who are on site at the facility and assign those operators to different vehicle systems to remotely control vehicle systems. This designation can be based on several factors, such as the current risk profile of a vehicle (which may indicate that more operators are needed to remotely control the vehicle when the risk profile is higher or that fewer operators are needed to remotely control the vehicle). vehicle when the risk profile is lower), the presence of an operator on board the vehicle (for example, fewer remote operators needed when an operator is on board), the occurrence of an emergency (for example, accident, such as a collision ) or failure of a vehicle or vehicle component (for example, designating more operators when this occurs), etc. At least one technical effect of the subject matter described here provides efficient designation and re-designation of operators to remotely control and / or monitor the movement of several different vehicles to ensure the simultaneous safe and timely movement of vehicles.
[013] Figure 1 illustrates an embodiment of a remote vehicle operator designation system (100). The designation system (100) operates to designate different human operators (102) or groups of operators to remotely control movements of vehicle systems (104) (e.g., vehicle systems (104A, 104B) in Figure 1). a
Petition 870190039552, of 04/26/2019, p. 178/339
10/136 vehicle system (104) can be formed by a single vehicle, or it can be formed by 2 or more vehicles. In relation to multiple vehicle systems (104), vehicle systems (104) can include two or more vehicles that are mechanically or logically coupled together. Vehicles can be mechanically coupled to each other when vehicles are mechanically coupled by a coupler, for example. With regard to logically coupled vehicle systems, two or more vehicles can be logically connected, but not mechanically connected when vehicles communicate with each other during the movement to coordinate the movements of the vehicles with each other and make the vehicles move together along one or more routes. Although only two vehicle systems (104) are shown in Figure 1, the designation system (100) can assign operators (102) to many more vehicle systems (104) for simultaneous remote control of vehicle systems (104). The operators (102) are shown in Figure 1 as Operator No. 1, Operator No. 2 and so on. Although only four operators (102) are shown in Figure 1, the designation system (100) can designate a much larger number of operators (102) to remotely control vehicle systems (104) (for example, up to fifty operators (102 ), up to 100 operators (102), etc.). Operators (102) can be on board and / or outside vehicle systems (104), as shown in Figure 1. In one example, an operator on board (102) can control the movement of the vehicle system (104) in the where the operator (102) is located. In another example, the operator on board (102) can control the movement of the vehicle system (104) in which the operator (102) is located and can remotely control the movement of a vehicle in the same vehicle system (104) and / or other vehicle system (104) (for example, if the vehicle system (104) in which the operator (102) is located has multiple propulsion generating vehicles). In another example, the operator
Petition 870190039552, of 04/26/2019, p. 179/339
11/136 on board (102) can remotely control the movement of another vehicle system (104) in which the operator (102) is not located from the vehicle system (104) in which the operator (102) is located.
[014] Operators (102) use remote control machines (106) (for example, “RC Machine No. 1”, and so on, in Figure 1) to monitor vehicle system operations (104) assigned to operators (102), and to remotely control the operations of vehicle systems (104). The machines (106) can optionally be referred to as a control system or remote control system, or can be included as part of a control system.
[015] Remote control machines (106) can each represent an autonomous or shared computing device, such as hardware circuits that include and / or are connected to one or more processors (for example, one or more arrays field programmable ports, one or more microprocessors and / or one or more integrated circuits). The processors of the remote control machines (106) operate to receive input from operators (102) of the corresponding machines (106) and to generate command messages that are communicated electronically to the vehicle systems (104) via, through, through one or more computerized communications networks (110). Networks (110) can represent networks made up of routers, transceivers, repeaters, modulators, satellites or the like, and allow remote control machines (106) to communicate wirelessly with vehicle systems (104), and can allow that sensors (112) arranged on board and / or outside vehicle systems (104) communicate the monitored characteristics of the movement of vehicle systems (104) and / or the routes to be taken. The sensors (112) can represent cameras, radar systems, temperature sensors, pressure sensors, tachometers, accelerometers or something
Petition 870190039552, of 04/26/2019, p. 180/339
12/136 like.
[016] Remote control machines (106) can remotely control the movement of vehicle systems (104) by sending command messages to controllers (114) ("Controller No. A" and "Controller No. B" in Figure 1 ) that are on board vehicle systems (104). In one embodiment, a single operator (102) can be assigned to remotely control several different (e.g., separate) vehicles (104). For example, a single operator (102) can be a machine (106) to remotely control multiple vehicles (104) moving in different directions, at different speeds, at different locations, etc., at the same time. Alternatively, multiple operators (102) can be assigned to control a single vehicle (104) at the same time.
[017] Controllers (114) on board vehicle systems (104) can represent hardware circuits that include and / or are connected to one or more processors. These processors operate to control the movement of the vehicle systems (104). For example, responsive to receiving a command signal from a remote control machine (106), a controller (114) on board a vehicle (104) can transmit the same command signal or form another command signal that is communicated to a propulsion system (116) (“Prop. System No. A” and “Prop. System No. B” in Figure 1) on board the same vehicle (104). The propulsion system represents mechanisms, engines, brakes or the like of vehicle systems (104) that operate to start or stop the movement of vehicle systems (104). Communication systems (118) ("Com. System" in Figure 1) on board vehicle systems (104) represent a communication circuit that sends and / or receives electronic signals and is used to communicate with control machines remote (106). Communication systems (118) can represent transceivers, modulators, routers or the like.
Petition 870190039552, of 04/26/2019, p. 181/339
13/136 [018] In one embodiment, the remote control machines (106) directly control the movement of vehicles (104) by sending these command signals to the controllers (114). For example, a command signal can be sent to a controller (114) from a machine (106) that automatically changes the vehicle's accelerator configuration, automatically engages the vehicle's brakes or automatically implements some other operational change in the vehicle. Optionally, the remote control machines (106) can indirectly control the movement of vehicles (104), such as by sending the command signals to the controllers (114) which they later display or otherwise present instructions to any operator on board ( for example, an operator (102) or another operator) of the vehicle system (104) on how to control the movement of the vehicle (104) on board the vehicle system (104) according to the command signal received from a machine remote control (106).
[019] The designation system (100) can communicate with remote control machines (106) and / or vehicle systems (104) via the network or networks (110). Alternatively, the designation system (100) can be formed as part of or shared with one or more of the remote control machines (106). The designation system (100) operates to determine time-varying risk profiles for each of the various separate vehicle systems (104). Time-varying risk profiles represent one or more risks to the path of separate vehicle systems (104) during travel of separate vehicle systems (104) that change with respect to time during travel of vehicle systems (104) .
[020] Figure 2 illustrates an example of a transport system (200) in which several of the vehicle systems travel due to the remote control implemented by the remote control machines (106) shown in Figure 1. There are four vehicle systems (104 ) shown in Figure 2 and
Petition 870190039552, of 04/26/2019, p. 182/339
14/136 marked (104A), (104B), (104C) and (104D). The vehicle systems (104) travel on several interconnected routes (202) of the transport system (200). These routes (202) can represent roads, trails, canals or the like. Several of the remote control machines (106) can remotely control the movements of the different vehicle systems (104A-D) at the same time. Remote control machines (106) can remotely control the separate movements of these vehicle systems (104), although vehicle systems (104) are traveling simultaneously on different routes (202), traveling in different directions on different routes (202) , traveling in different directions on the same route (202), traveling in the same direction on different routes (202) and / or traveling to different locations.
[021] The designation system (100) can determine time-varying risk profiles for separate vehicle systems (104), identifying one or more time-varying risks and / or one or more static risks to the systems' safe path separate vehicles (104). Time-varying risks may represent factors involved in the safe course of vehicle systems (104) that change over time. Static risks can represent factors involved in the safe course of vehicle systems (104) that do not change over time. Time-varying risks may be different for different locations along the route or routes (202) that are covered by the vehicle system (104) during the next trip, and / or may be different at different times or times elapsed during the next vehicle system travel (104).
[022] Time-varying risks can include a variety of factors that negatively affect the ability of a vehicle system (104) to otherwise travel safely without incident between the
Petition 870190039552, of 04/26/2019, p. 183/339
15/136 departure and destination for future travel. As an example, a time-varying risk may include if a vehicle system (104) is to travel through an area having a population density that is greater than a designated limit. Urban or more densely populated areas may pose greater risks to the safe route of the vehicle system (104) through the area due to the increased presence of pedestrians, other vehicle systems, restrictions on how fast vehicle systems (104) can move , restrictions on the types of cargo that can be transported through the area, or something similar. For example, a vehicle system (104) traveling through a densely populated area may be more likely to be involved in a collision with a pedestrian or other vehicle system than if the same vehicle system travels in a sparsely populated area.
[023] Another example of time-varying risk includes whether a vehicle system (104) is traveling with a dangerous load. The dangerous cargo may be a cargo that poses a security threat to those on board the vehicle system (104) and / or to those outside the vehicle system (104). Examples of dangerous cargo or cargo include radioactive material, corrosive material, flammable material, explosive material or the like. Vehicle systems (104) carrying dangerous cargo may be associated with a higher risk profile than vehicle systems (104) that do not carry such cargo. Traveling with a dangerous cargo can be a time-varying risk, since the dangerous cargo can only be carried by the vehicle system (104) during part of a future journey. For example, the vehicle system (104) may stop at one or more intermediate locations between the departure location at a travel destination to pick up and subsequently leave the dangerous cargo. The risk profile for a vehicle system (104) may increase while the hazardous load is
Petition 870190039552, of 04/26/2019, p. 184/339
16/136 carried by the vehicle system (104), and may decrease after the dangerous cargo is discharged.
[024] Another example of a time-varying risk includes a predicted climatic condition. Some climatic conditions, such as precipitation, strong winds or the like, can increase the risk of an accident or operational failure of certain vehicle systems (104). For example, vehicles traveling in conditions of ice or snow may have an increased risk profile compared to vehicle systems (104) traveling in dry and warmer conditions. As another example, vehicle systems (104) that travel through areas with strong side winds (winds that are not with or directly against the direction of travel, but closer to the perpendicular to a direction of travel) may have a profile of greater risk during the journey through these winds during other times.
[025] Another example of time-varying risk is a dangerous section of a route (202). Some sections of routes (202) may include steep grades, sharp turns, wavy surfaces and the like. These route characteristics can increase the forces between wagons between vehicles in multi-vehicle systems (104) and therefore can increase the risk that a vehicle system (104) will disintegrate or leave the route (202).
[026] Another example of a time-varying risk is a geographic area with vehicle traffic congestion. Some sections of the transport system formed by the routes (202) may have many vehicle systems traveling simultaneously in sections of routes (202) that are close to each other during certain hours of the day. The presence or expected presence of more than a designated number of vehicle systems (104) per unit area can indicate traffic congestion, and can increase the risk profile of a vehicle system (104) traveling
Petition 870190039552, of 04/26/2019, p. 185/339
17/136 to or through that area.
[027] Another example of time-varying risk is a section of a route (202) that is undergoing maintenance. A route (202) that is under maintenance may pose a greater risk for a safe route due to the presence of maintenance personnel, equipment and the like, on or near route 202 (202).
[028] As regards the static risks that make up the risk profiles, an example is a type of cargo carried by a vehicle system (104). As described above, the presence of dangerous cargo carried by a vehicle system (104) can increase the risk profile for that vehicle system (104). Although the dangerous cargo can be a time-varying risk, this cargo can also be a static risk when the cargo is carried by the vehicle system (104) for an entire journey. Another example of a static hazard includes a size of a vehicle system (104). The size of the vehicle system can represent the length, weight, number of vehicles or the like, in the vehicle system (104). Longer vehicle systems, vehicle systems that are heavier and / or vehicle systems (104) formed from many more vehicles, may be associated with greater static risks than vehicle systems that are shorter, lighter and / or vehicles.
[029] A static risk can also be the presence (or absence) of an operator on board the vehicle system (104) and / or his experience, qualifications and performance history. Some vehicle systems (104) may have a human operator traveling in the vehicle system (104). The presence of the operator (102) on board can reduce the risk profile for that vehicle system (104) due to the fact that the operator on board is available to correct any incorrect actions directed by the remote control machine (106), to respond quickly emergency situations
Petition 870190039552, of 04/26/2019, p. 186/339
18/136 or failure, or something like that. On the other hand, vehicle systems (104) that do not have an operator on board may be associated with higher risk profiles.
[030] With respect to the example of the transport system (200) shown in Figure 2, the transport system (200) is shown to include a densely populated geographical area (204) than one or more of the vehicle systems (104A, 104B , 104D) may be moving in the direction. This densely populated area (204) may represent the boundaries of a city or municipality, or it may represent another geographical fence around a geographical area where the population exceeds one or more designated thresholds.
[031] Optionally, the geographical area (204) can represent an area of increased vehicle traffic. For example, the area (204) can represent parts of the routes (202) having a number of vehicle systems that exceed the limit called the sum. In other words, the area (204) can represent an area with congested vehicular traffic, through which the path of one or more additional vehicle systems (104) can be associated with increased risk. The designation system (100) can determine where the geographical area (204) is located based on a designated boundary (for example, city boundaries), based on an operator-defined boundary (for example, city boundaries). area where the population increase is known or believed to be located), or based on monitored traffic patterns. For example, global positioning system receivers arranged on board vehicles (104), traffic cameras or other sensors can monitor how many vehicle systems (104) are in the area (204). If the number of vehicle systems (104) within the area (204) is very large, if the movement speed of the vehicle systems (104) in the areas starts to decrease or is slower than a designated speed, etc., the designation system (100) can determine that the geographical area
Petition 870190039552, of 04/26/2019, p. 187/339
19/136 (204) is associated with traffic congestion.
[032] The increase in the risk profile due to traffic congestion can be a time-varying risk, which is predicted based on previous traffic patterns. For example, if the area (204) was found to be associated with heavy traffic during certain periods of the day (for example, during the morning or evening rush hour), then the time-varying risk profile for a vehicle system ( 104) that is scheduled or expected to travel through the area (204) during one or more of these periods of the day may exhibit a greater risk than for vehicle systems that do not travel through that area (204) or the vehicle systems that travel through the area (204 ) at a time when increased traffic is not expected.
[033] The transport system (200) is also shown with a designated area of dangerous terrain (206). This area (206) can represent the part of a route (202) having dangerous route conditions. Dangerous route conditions can include steep grades, sharp turns, wavy parts of a route (202) or something like that. Optionally, dangerous route conditions may include maintenance or repair of the route segment (202), due, at least in part, to the presence of personnel in or near the repaired section of the route (202). The path of the vehicle system (104) through the area (206) can be associated with an increased risk profile during the path of the vehicle system (104) through the area (206).
[034] A predicted climate area is also shown in Figure 2 (208). The climatic area (208) can represent the geographical area through which one or more routes (202) extend, and this is associated with bad or dangerous weather conditions. An anticipated dangerous weather condition may include a prediction that the weather in the area (208) will be harmful to travel during one or more times than the vehicle system

20/136 (104) is programmed or otherwise expected to travel through the area (208). For example, area (208) may represent locations where the climate is expected to include precipitation, high temperatures, strong crosswinds or other dangerous conditions. Since climatic conditions may change with time, the predicted climate area (208) may be associated with the variable risk over time. Alternatively, if a predicted weather pattern is not expected to change over an extended period of time, then the predicted climate area (208) can be a static risk to the path of vehicle systems (104).
[035] In one embodiment, the same climatic condition may be a dangerous condition that increases the risk profile of one vehicle, but it may not be a dangerous condition that increases the risk profile of another vehicle. In other words, vehicles may have different changes in risk profiles for the same climatic condition, depending on the parameters or characteristics of the vehicles. Taller vehicles (for example, extend to greater heights above the route or surface being traveled), vehicles with centers of gravity that are higher above the route or the surface, lighter vehicles, etc., may have greater risks during the route through areas of higher wind speed. For example, empty coal wagons on trains may be more susceptible to tipping or derailment during travel in windy areas (when compared to coal-filled wagons).
[036] Figure 3 illustrates examples of time-varying risk profiles (304) (for example, risk profiles (304A, 304B, 304D)) for future trips of different vehicle systems (104) (for example, vehicles (104A, 104B, 104D)). The risk profile (304A) represents the quantified risks for the next trip of the vehicle system (104A) along the route (202) shown in Figure 2, the risk profile (304B) represents the risks
Petition 870190039552, of 04/26/2019, p. 189/339
21/136 quantified for the next trip of the vehicle system (104B) along another route (202) shown in Figure 2, and the risk profile (304D) represents the quantified risks for the next trip of the vehicle system (104D ) along another route (202) shown in Figure 2. The risk profiles (304) are shown beside a horizontal axis (300) that represents time or distance over the next trip. The risk profiles (304) are also shown next to a vertical axis (302) that represents quantified risks during the trip.
[037] The designation system (100) can quantify risks by assigning numerical values to different vehicle systems (104) based on the time-varying and / or static risks associated with each vehicle system (104) at different times or locations for the next trip. The values assigned to the different risks can be defined by an operator of the designation system (100) or can have default values. Increased values can be assigned to greater risks, with greater risks associated with greater probability of vehicle accidents, failures, etc. For example, a vehicle system (104) having a total weight above an upper designated threshold can be designated a risk value of ten. If the vehicle system (104) has a total weight that is less than the upper threshold, but above a lower threshold, then the risk value can be reduced to eight. If the vehicle system (104) also travels a dangerous section of routes (202), then the risk value for the vehicle system (104) may increase in the risk profile by fifteen while the vehicle system (104) travels through the dangerous route section. If the vehicle system (104) does not travel through a densely populated area, then the risk may not be increased (or may be reduced, as by a value of five). These numbers are provided only as a few examples, and other values can be used.
Petition 870190039552, of 04/26/2019, p. 190/339
22/136 [038] For example, the risk profile (304A) shows a relatively low risk for a first part (306) of the vehicle system trip (104A). This low risk is due to the fact that the vehicle system (104A) is formed from a single vehicle (with multiple vehicle systems being designated the highest risk), the vehicle system (104A) is not carrying dangerous cargo, the system vehicle (104A) is not traveling a dangerous part of the route (202), the vehicle system (104A) is traveling in a rural area (for example, sparsely populated area), and the vehicle system (104A) is light ( for example, not carrying a large load). During a subsequent part (308) of the trip, the vehicle system (104A) is traveling through the area (204) where there is significantly more population. This change increases the risk to the vehicle system (104A) while traveling through the densely populated area (204), as shown in Figure 3. When leaving the densely populated area (204), the risk represented by the risk profile (304A ) decreases again due to the exit of the densely populated area (204).
[039] The risk profile (304B) shows a relatively low risk for the entire trip of the vehicle system (104B). This low risk may be due to the fact that the vehicle system (104B) is formed by a single light vehicle that is not carrying any dangerous or heavy cargo. Additionally, the vehicle system (104B) does not travel through densely populated areas (204) or dangerous parts (206) of the routes (202). But, the risk profile (304B) of the vehicle system (104B) can be modified to show an increased risk (310). This increased risk (310) may represent a change in the weather forecast that shows a high probability (for example, greater than 70%) that the vehicle system (104B) will travel through the bad weather area (208) shown in Figure 2. After the vehicle system (104B) is expected to leave the bad area (208)
Petition 870190039552, of 04/26/2019, p. 191/339
23/136 time, the risk profile (304B) decreases to indicate the reduced risk due to the vehicle system (104B) no longer traveling through bad weather.
[040] The risk profile (304D) shows a greater risk for the vehicle system (104D) during an initial part (312) of a trip than the risk for the initial parts of the vehicle system trips (104A, 104B ). This is due to the fact that the vehicle system (104D) is longer, having more vehicles in the vehicle system (104D), and potentially because the vehicle system (104D) is heavier than the vehicle systems (104A) , 104B). The risk profile (304D) increases to a higher level (314) due to the passage of the vehicle system (104D) through the densely populated area (204) shown in Figure 2 before decreasing slightly (due to the exit from the densely populated area ( 204)). The risk profile (304D) then remains slightly elevated in a subsequent part (318) of the trip (in relation to the initial part (312) of the trip) due to the vehicle system (104D) traveling through the area (206) where the route (202) can include many curves, steep grades, maintenance crews or the like. The risk profile (304D) then decreases to the initial risk level in the vehicle system (104D) exiting the area (206).
[041] The designation system (100) can then determine a demand for operator personnel for the next trips of the vehicle systems (104) based on the time-varying risk profiles (304) of the separate vehicle systems (104) . The demand for operator personnel can be a number representing how many operators (102) will be required to remotely control and / or monitor vehicle systems (104), the number being based on the risk profiles (304) of vehicle systems ( 104). The demand for operator personnel can be expressed as a number that changes over time to reflect that the risk profiles (304) of one or more vehicle systems (104) change over time.
Petition 870190039552, of 04/26/2019, p. 192/339
24/136
The demand for operator personnel can be a number that represents a proportion of vehicle systems (104) that are assigned to operators (102) for monitoring and / or remote control of vehicle systems (104). For example, a ratio of two may indicate that a single operator (102) can be assigned to remotely control and / or monitor two different and separate vehicle systems (104) (which are traveling at the same time, but on different routes, in different speeds, in different directions, to different locations and / or from different locations).
[042] The designation system (100) may determine that more operators may be required to remotely control the movement of a vehicle system (104) during periods of time when the risk profile (304) of the vehicle system (104 ) is higher, and that fewer operators may be needed during other periods of time when the risk profile (304) is lower. For example, the higher risk profile (304D) of the vehicle system (104D) may result in the designation system (100) determining that an operator (102) should be assigned to remotely control (and monitor) fewer vehicle systems (including the vehicle system (104D)) throughout the journey of the vehicle system (104D), while another operator (102) who is designated to remotely control each of the vehicle systems (104A, 104B) can be assigned to additional or more vehicle systems during the entire travels of vehicle systems (104A, 104B) due to the lower risk profiles (304A, 304B) of vehicle systems (104A, 104B).
[043] The determination of how many vehicle systems (104) can be assigned to an operator (102) (or how many vehicle systems (104) to which an operator (102) can be assigned) may not be a static number. The designation system (100) can vary the number of vehicle systems (104) that can be assigned to an operator (102)
Petition 870190039552, of 04/26/2019, p. 193/339
25/136 based on increases (or decreases) in risk profiles (304). For example, while the designation system (100) can determine that more vehicle systems (104) (including the vehicle system (104B)) can be assigned to the same operator (102) due to the relatively low risk profile (304B) vehicle system (104B) for the period of the upcoming scheduled trip. The increased risk during the part (306) in the risk profile (304B) due to the climatic area (208) can cause the designation system (100) to reduce the number of vehicle systems (104) assigned to the operator (102) which is also remotely controlling the vehicle system (104B) during the path of the vehicle system (104B) in the area (208). As another example, the designation system (100) may determine that the number of vehicle systems (104) assigned to the operator (102) who are controlling the vehicle system (104D) can be increased during the journey out of the densely populated area. populated (204) and area (206) due to decreased risk at these locations or times, but that fewer vehicle systems (104) can be assigned to the operator (102) who is remotely controlling the vehicle system (104D) while the vehicle system (104D) travels through areas (206, 208) associated with increased risks.
[044] In one embodiment, the designation system (100) can determine how many vehicle systems (104) can be assigned to the same operator (102) by examining the risk profiles (304) of the vehicle systems (104). For example, the designation system (100) can determine a risk threshold for an operator (102) that is based on the operator's experience (102), the operator's training (102), the continuous hours that the operator (102) has worked and the like. Greater skill, more training and fewer hours of continuous work can be associated with higher thresholds for the operator (102), indicating that better operators
Petition 870190039552, of 04/26/2019, p. 194/339
26/136 trained, experienced and rested (102) may be able to remotely control more vehicle systems (104) at the same time as an operator (102) with less experience, less training and / or who may be fatigued. The risk values represented by the vehicle systems (104) at different times can be added, and only the vehicle systems (104) having a total sum of risk values that do not exceed the operator threshold (102) can be assigned to that operator (102). Different combinations of vehicle systems (104) for the operator (102) can be examined.
[045] The designation system (100) can also determine how many operators (102) are required for remote control of vehicle systems (104) based on the operational functions to be performed by the operators (102). Some operators (102) may be assigned to a vehicle system (104) to monitor the movement and / or other operations of the vehicle systems (104), but not to control an accelerator and / or brake on the vehicle systems (104) . These operators (102) can remotely monitor the vehicle system (104) to determine if an emergency, accident or failure is occurring or about to occur (or that other unsafe or unexpected conditions arise) and then take over or assist with control the movement of the vehicle system (104), responsive to determining that the emergency, accident or failure is occurring or about to occur. Other operators (102) can be assigned to a vehicle system (104) to remotely control (and monitor) the movement and / or other operations of the vehicle systems (104). The machines (106) can modify the characteristics, data and inputs available to operators (102) based on the objective designation (monitor or control). Since the mental attention required by an operator (102) to remotely control the movement of a vehicle system (104) is greater than the mental attention required to
Petition 870190039552, of 04/26/2019, p. 195/339
27/136 remotely monitoring the movement of a vehicle system (104) (but not controlling), the designation system (100) can determine that fewer operators (102) are required for vehicle systems (104) being monitored, but not remotely controlled (and that more operators (102) are needed for vehicle systems (104) that are controlled remotely). As a result, the designation system (100) can assign more vehicle systems (104) to operators (102) who are remotely monitoring more vehicle systems (104) (than other operators (102)), while fewer vehicle systems (104) are assigned to operators (102) who are remotely controlling more vehicle systems (104) (than other operators (102)).
[046] The demand for operator personnel that is determined by the designation system (100) can also be based on whether any travel of the vehicle systems (104) requires operators (102) to have specialized qualifications. For example, the designation system (100) may determine that vehicle systems (104) having large risk profiles (304) may require operators (102) to have at least a designated number of years of experience in remotely controlling systems vehicles (104). The designation system (100) can determine which vehicle system trips (104) extend across certain geographical areas (for example, with difficult terrain, such as area (206), with dense populations, such as area (204), etc.) may require operators (102) to have experience in remotely controlling vehicle systems (104) across these types of areas. The designation system (100) may determine that vehicle systems (104) carrying heavy and / or dangerous cargo may require operators (102) to have specialized training in remotely controlling such vehicle systems (104). The designation system (100) can determine that the travel of the
Petition 870190039552, of 04/26/2019, p. 196/339
28/136 vehicle systems (104) that extend across certain geographic areas having different or restrictive laws or regulations may require operators (102) to have experience in remotely controlling vehicle systems (104) across those types of areas, having specialized training and / or having specialized licenses. For example, some areas may have laws that require a remote operator (102) to have a specific license issued by a government agency or agency. The designation system (100) can determine that the vehicle system (104) has at least one operator (102) with the necessary experience, skill, licensing, etc., for a journey of the vehicle system (104) that passes through any of these areas.
[047] The demand for operator personnel that is determined by the designation system (100) can represent a number of operators (102) that are required to be available (for example, on site at a facility where the machines (106) are to control and / or remotely monitor vehicle systems (104) at different times. As the risk profiles (304) of vehicle systems (104) change over time, the number of operators (102) required to remotely control and / or monitor vehicle systems (104) can also change over time .
[048] The designation system (100) can then designate operators (102) to remotely monitor and / or control vehicle systems (104) based on demand for operator personnel and time-varying risk profiles (304 ) of vehicle systems (104). While determining the required operator personnel involves the designation system (100) determining how many operators (102) are needed (and, optionally, if any operators (102) with specialized skills are required), the designation of operators (102) a systems
Petition 870190039552, of 04/26/2019, p. 197/339
29/136 of vehicles (104) may involve the designation system (100) by selecting individual operators (102) to remotely monitor and / or control certain vehicle systems (104).
[049] The designation of operators (102) can involve the designation system (100) by sending control signals to the machines (106) of the operators (102) assigned to different vehicle systems (104). This control signal can direct the machines (106) to establish communication with the communication systems (118) of the vehicle systems (104) being monitored and / or controlled. The designation system (100) can optionally send a control signal to the controllers (114) of the vehicle systems (104) to inform the controllers (114) of which machines (106) will be used to remotely monitor and / or control the systems corresponding vehicles (104). The operators (102) can then monitor the movement of the vehicle systems (104) to which the operators (102) are assigned, viewing data obtained or emitted by the sensors (112) and / or can remotely control the movement of the vehicle systems ( 104) to which the operators (102) are assigned, sending control signals from the machines (106) to the controllers (114), who then control the propulsion systems (116) according to the control signals to implement the control actions. remote control by operators (102).
[050] Although the designation system (100) can assign some operators (102) to some vehicle systems (104) based on just how many operators (102) are required for each vehicle system (104) (based on profiles risk (304) of vehicle systems (104)), optionally, the designation system (100) can designate one or more operators (102) to a vehicle system (104) based on other factors. As an example, the designation system (100) can designate operators
Petition 870190039552, of 04/26/2019, p. 198/339
30/136 (102) to vehicle systems (104) based on operator qualification levels. Operators (102) who have more experience, who have received more training, who have certain licenses, etc., can be assigned to vehicle systems (104) which have the highest risk profiles (304) (for example, during periods where the risk profiles (304) are higher or higher). Conversely, operators (102) who have less experience, who have received less training, who do not have certain licenses, etc., can be assigned to vehicle systems (104) with lower risk profiles (304).
[051] In one example, the designation system (100) can determine a level of qualification necessary to remotely control a vehicle system (104) based on the risk profile (304) of the vehicle system (104). This qualification level can be an amount defined by the operator or user of experience, training and / or licenses that an operator (102) is required to have before that operator (102) can be assigned to a vehicle system (104) associated with the qualification level required. Vehicle systems (104) that have risk profiles (304) that exceed one or more thresholds may have required qualification levels that require a designated operator (102) to have at least five years of experience (or another time period) to control and / or remotely monitor vehicle systems (104) with high risk profiles (304). Other vehicle systems (104) that are planning to travel through a densely populated area, bad weather forecast areas, areas with dangerous routes (202), etc., may have similar qualification level requirements. As another example, a vehicle system (104) carrying dangerous cargo may require an operator (102) to have a certain license. In another example, the level of qualification required may change based on the functions to be performed by a
Petition 870190039552, of 04/26/2019, p. 199/339
31/136 operator (102) for a vehicle system (104). For example, a vehicle system (104) requiring an operator (102) designated to remotely monitor sensor data (112) on board the vehicle system (104) (but not to control the movement of the vehicle system (104)) it may have a lower level of qualification required than another vehicle system (104) which requires an operator (102) designated to remotely control the movement of the vehicle system (104).
[052] The designation system (100) can examine the required qualification level (s) of a vehicle system (104) and can examine the operator qualification levels (102) that can potentially be assigned to the vehicle system (104). The designation system (100) cannot designate any operator (102) who does not have qualifications that meet or exceed the qualification levels required for the vehicle system (104). The designation system (100) can designate an operator (102) who has qualifications that meet or exceed the qualification levels required for the vehicle system (104).
[053] The designation system (100) can assign multiple operators (102) to the same vehicle system (104) based on a disparity in training or experience between operators (102). For example, the designation system (100) can examine the qualification levels of multiple operators (102) and designate a more experienced or trained operator (102) and a less experienced or trained operator (102) for the same vehicle system ( 104). This can allow the less experienced operator (102) to learn from the more experienced operator (102) during remote control and / or monitoring of the vehicle system (104).
[054] The designation system (100) can assign operators (102) to vehicle systems (104) based on geographical regions or areas in which the vehicle systems (104) are traveling or will be
Petition 870190039552, of 04/26/2019, p. 200/339
32/136 walking. Certain operators (102) may have more experience or training in remotely controlling the movement of vehicle systems (104) in certain geographic regions. For example, one operator (102) may have more experience in remotely controlling vehicle systems (104) that travel through mountainous regions, while another operator (102) may have more experience in remotely controlling vehicle systems (104) that travel through mountainous regions. densely populated areas. The designation system (100) can examine where the vehicle systems (104) will be traveling and can examine whether any operator (102) has experience in controlling vehicle systems (104) in the same geographical area. The designation system (100) can then designate the operator or operators (102) with experience in the area (s) where a vehicle system (104) will travel to that vehicle system (104).
[055] In one embodiment, the designation system (100) can determine whether to designate an operator (102) to remotely control the movement of a vehicle system (104) based on whether another operator is on board vehicle system (104) (during the movement that would be controlled remotely). The designation system (100) can change the risk profile (304) and / or the level of qualification required for the remote operator (102) based on the presence or absence of an operator on board. For example, the risk profile (304) may decrease and / or the required skill level may decrease when an operator is on board the vehicle system (104) to assist the operator (102) who is remotely controlling the movement of the system vehicle (104).
[056] The designation system (100) can determine which operators (102) should be assigned to one or more of the vehicle systems (104) based on how long the operator (s) (102) have worked for remotely monitor and / or control the same and / or other
Petition 870190039552, of 04/26/2019, p. 201/339
33/136 vehicle systems (104). For example, some operators (102) may be assigned to more vehicle systems (104) and / or may be assigned for longer periods of time to remotely control and / or monitor vehicle systems (104). This may be due to the skill and / or training of the operator (102), the low supply of operators (102) to designate, or other factors. The designation system (100) can track how long an operator (102) has worked continuously on monitoring and / or remote controlling a vehicle system (104) and, if the operator (102) has worked continuously for longer than a threshold designated (for example, six hours, a single work shift or other limit), then the designation system (100) may not designate that operator (102) to another vehicle system (104). This can help prevent some operators (102) from working too long to remotely control and / or monitor vehicle systems (104), which could run the risk of operator error due to fatigue.
[057] The designation system (100) can monitor the fatigue or agility of the operators (102) and / or the operators on board (102) associated with the vehicle systems (104) assigned to the operator (102). For example, the designation system (100) may include one or more sensors that monitor characteristics of operators (102) to determine whether these characteristics indicate that one or more of the operators (102) is not alert or is becoming fatigued. These sensors can include a camera (and optionally one or more processors) that monitors the eyes of an operator (102) to ensure that the eyes of the operator (102) are open, attentive and focused on the input / output device used by the operator ( 102) to remotely control and / or monitor the vehicle system (s) (104). The sensors can include an input / output device, such as a touch screen, electronic viewfinder with mouse or electronic keyboard, etc., which provides the operator (102) with interactive questions. Answers to questions (and / or how
Petition 870190039552, of 04/26/2019, p. 202/339
34/136 fast the operator (102) responds) can be used by the designation system (100) to determine whether the operator (102) is fatigued or alert. If an operator (102) becomes fatigued or is not alert, then the designation system (100) can avoid assigning vehicle systems (104) to the operator (102) and / or can reassign one or more (or all) systems vehicles (104) assigned to that operator (102) to another operator (102).
[058] The designation system (100) can determine which operators (102) should be assigned to multiple vehicle systems (104) based on how many vehicle systems (104) will be controlled and / or monitored remotely by the operator (102) . For example, the designation system (100) can avoid having an operator (102) assigned to many vehicle systems (104) using one or more limits on how many vehicle systems (104) can be monitored and / or controlled remotely by the operator (102). The limit on how many vehicle systems (104) can be assigned to or with the same operator (102) may vary based on the qualifications of the operator (102), the role of the operator (102) and / or the risk profiles (304 ) of vehicle systems (104). For example, operators (102) with more training and / or skill may be assigned to more vehicle systems (104) than operators (102) with less training and / or skill. The operators (102) that will be assigned to monitor the vehicle systems (104) can be assigned to more vehicle systems (104) than the operators (102) who are assigned to remotely monitor the vehicle systems (104). Operators (102) who are assigned vehicle systems (104) with lower risk profiles (304) can be assigned more vehicle systems (104) than operators (102) assigned to vehicle systems (104) with higher profiles risk (304).
[059] The designation system (100) can change which
Petition 870190039552, of 04/26/2019, p. 203/339
35/136 operators (102) are designated to remotely monitor and / or control a vehicle system (104) while traveling (for example, while the vehicle system (104) is in motion). The designation system (100) can direct one or more operators (102) to stop monitoring and / or remotely control a vehicle system (104) and can direct one or more other operators (102) to start monitoring and / or remote control of the same vehicle system (104). The designation system (100) can change the operator's designation to a vehicle system (104) responsive to the risk profile (304) to the changing vehicle system (104). For example, the risk profile (304) of a vehicle system (104) may change after the vehicle system (104) has departed from a departure point for a trip, and before the vehicle system (104) has reached a final location for the trip. This change may be due to a variety of factors of change, such as a change in weather conditions, a change in traffic congestion, a change in a route state (202) (for example, from no maintenance being performed for a maintenance being performed, from a bridge being lowered to allow vehicle systems (104) to pass over the bridge to a bridge being raised to prevent vehicle systems (104) from passing, etc.), detecting an emergency situation, etc. . If the risk profile (304) increases (for example, to or above another higher threshold), then the designation system (100) can designate one or more additional operators (102) to remotely monitor and / or control the vehicle (104) associated with the risk profile (304). If the risk profile (304) decreases (for example, below the threshold), then the designation system (100) can remove one or more of the operators (102) already assigned to remotely monitor and / or control the vehicle system ( 104) associated with the risk profile (304) to remotely monitor and / or control the vehicle system (104) or to stop monitoring and / or
Petition 870190039552, of 04/26/2019, p. 204/339
36/136 by remotely controlling the vehicle system (104).
[060] As an example, if a vehicle system (104) is involved in an accident or the risk profile (304) for that vehicle system (104) becomes too large (for example, exceeds an upper limit), then a dedicated specialist operator can be assigned to remotely control and / or monitor the vehicle system (104). This operator (102) may have much more experience and / or training than other operators (102), and may be more suitable for controlling a vehicle system (104) that has a very high risk for the continuous safe route.
[061] The designation system (100) can change which operators (102) are assigned to different vehicle systems (104) at different times based on the need for an operator (102) to have specialized qualifications. For example, if the vehicle system (104) obtains and carries a dangerous cargo during part of the journey, and there is a need for an operator (102) having training to remotely control a vehicle system (104) that carries the dangerous cargo, then the designation system (100) can designate such an operator (102) and connect the machine (106) of the operator (102) to the vehicle system (104) while the vehicle system (104) carries the dangerous cargo.
[062] The designation system (100) can designate or change a designation of one or more operators (102) to control and / or remotely monitor a vehicle system (104) responsive to detect that an emergency has occurred. The emergency situation may be a collision or other accident, failure of one or more components of the vehicle system (104), or the like. The controller (114) of the vehicle system (104) can notify the designation system (100) of the emergency situation. In response to the detection of the emergency situation, the designation system (100) can modify the risk profile (304) of the vehicle system (104) and,
Petition 870190039552, of 04/26/2019, p. 205/339
37/136 optionally, one or more other vehicle systems (104) that are traveling towards the location of the emergency situation. The designation system (100) can automatically designate one or more additional operators (102) to monitor and / or control the vehicle system (104) involved in the emergency and / or for one or more other vehicle systems (104) that travel near or towards the emergency situation. For example, in the event of a collision or derailment involving a first vehicle system (104), the designation system (100) may designate an additional operator (102) to remotely monitor and / or control the first vehicle system ( 104) and / or a second vehicle system (104) that is traveling towards the collision or derailment site.
[063] Optionally, the designation system (100) can have a restriction on the frequency with which a change in the designation of the operator occurs. The restriction can prevent or prevent an operator (102) from being frequently reassigned to another vehicle system (104). The designation system (100) cannot alter the vehicle system (s) (104) that an operator (102) is assigned to more than a designated number of times per unit time. For example, the designation system (100) cannot change the vehicle system (104) that is assigned to an operator (102) if that operator has been assigned or reassigned to another vehicle system (104) more than three times in the previous hour. Alternatively, the designation system (100) may allow more or less frequent re-designations of operators (102).
[064] The designation system (100) may have a restriction on when a change in operator designation occurs. The constraint may prevent a vehicle system (104) from changing which operator (102) is controlling and / or remotely monitoring the vehicle system (104) during
Petition 870190039552, of 04/26/2019, p. 206/339
38/136 the times when the vehicle system (104) is moving and / or located in an area with an increased risk profile (for example, the risk profile exceeds a designated limit).
[065] As another example, the designation system (100) may have a restriction that does not allow an operator (102) to be assigned to a vehicle system (104) if the current travel of the vehicle system (104) is not scheduled to finish (or not expected to finish based on current location and vehicle system speed (104)) before an operator's work shift (102) ends. For example, the designation system (100) may not allow operators (102) to remotely monitor and / or control vehicle systems (104) for longer than a continuous period of time (for example, four hours or another period to reduce the possibility of operator error due to fatigue.
[066] Another example of a restriction on the change of operator designation includes a limit on how many vehicle systems (104) are re-designated at the same time. In other words, the designation system (100) can change an operator designation (102) to remotely control and / or monitor vehicle systems (104) only when the operator (102) is being reassigned to at least one designated number of multiple vehicle systems (104). The designation system (100) may try repeatedly (and often) to avoid changing the operator's designation to the same vehicle system (104). The designation system (100) can change the operator's designation for a group of multiple vehicle systems (104), and not change the designation for smaller groups of vehicle systems (104). For example, the designation system (100) can only reassign at least three or more (or other lower limit) vehicle systems (104) to the same operator (102). If less than the lower limit of vehicle systems (104) needs to be re-assigned to that operator (102),
Petition 870190039552, of 04/26/2019, p. 207/339
39/136 the designation system (100) will attempt to assign the vehicle systems (104) to another operator (102), wait to change the designation for the operator (102) until there is at least the lower limit of vehicle systems ( 104) that need to be reassigned to the operator (102), or will not reassign vehicle systems (104) to that operator (102).
[067] The operator (102) can be re-assigned to a group of vehicle systems (104) based on common characteristics between the vehicle systems (104) and / or planned routes of the vehicle systems (104). For example, an operator (102) can be reassigned to a group of vehicle systems (104) that travel or are scheduled to travel in a common geographic region. Operator (102) can be assigned to vehicle systems (104) that travel in the same city, county, county, state, multi-state region (for example, the six most southwestern states of the continuous states in the United States of America) , country, area with the same time zone, or something like that. If two or more vehicle systems (104) in a first group travel or are programmed to travel in different regions, then the operator (102) may not be assigned to all vehicle systems (104) in the first group. Instead, the operator (102) can be assigned to a second, different group of vehicle systems (104) (which can include one or more, but not all, of the vehicle systems (104) in the first group).
[068] As another example, an operator (102) can be reassigned to a group of vehicle systems (104) that all carry the same type of cargo. The operator (102) can be assigned to vehicle systems (104) that carry the same type of dangerous cargo (for example, all cargo is corrosive, all cargo is radioactive or the like). Optionally, the operator (102) can be assigned to vehicle systems (104) that carry the same amount of cargo. For example, in a
Petition 870190039552, of 04/26/2019, p. 208/339
40/136 embodiment, for an operator (102) to be assigned to several vehicle systems (104), the vehicle systems (104) must be carrying the same load weight or the load weight in each vehicle system ( 104) must be within a designated range (for example, 10%) of each.
[069] As another example, an operator (102) can be reassigned to a group of vehicle systems (104) that carry or are programmed to carry the same type of cargo. The operator (102) can be assigned to vehicle systems (104) that carry the same type of dangerous cargo (for example, all cargo is corrosive, all cargo is radioactive or the like). Optionally, the operator (102) can be assigned to vehicle systems (104) that carry the same amount of cargo. For example, in one embodiment, for an operator (102) to be assigned to multiple vehicle systems (104), the vehicle systems (104) must be carrying the same load weight or the load weight in each system. vehicle (104) must be within a designated range (for example, 10%) of each.
[070] As another example, an operator (102) can be reassigned to a group of vehicle systems (104) that all travel in the same direction. The operator (102) can be assigned to vehicle systems (104) that move west (for example, more west than north, south or east), even on different routes (202). For example, the designation system (100) can designate the same operator (102) to remotely monitor and / or control multiple vehicle systems (104) traveling in the west direction (for example, a direction that is closer to being directly west) than any other direction) in the same state, while another operator (102) of several other vehicle systems (104) traveling in a north direction (for example, a direction that is closer to being directly north than any other direction) in same state, and so
Petition 870190039552, of 04/26/2019, p. 209/339
41/136 on.
[071] Optionally, the designation system (100) can modify which operator (102) is assigned to a vehicle system (104) based on a request received from the operator (102). Operators (102) may request a change in the vehicle system designation due to the operator (102) who wishes to be assigned to certain vehicle systems (104), due to an emergency involving the operator (102), the operator (102) needing a break, or for a variety of other reasons.
[072] Optionally, a passenger (120) (shown in Figure 1) can be located on board a vehicle system (104) with or without an operator (102) on board the same vehicle system (104). The passenger (120) can provide a request to the designation system (100) to change which operator (102) is remotely controlling the vehicle system (104). For example, the passenger (120) may be concerned that the operator (102) on board or outside, who controls the movement of the vehicle system (104), is putting the passenger (120) at risk. The passenger (120) may request that the designation system (100) designate more operators (102) to control and / or remotely monitor the vehicle system (104) or that another different operator (102) be designated to control and / or remotely monitor the vehicle system (104).
[073] If the designation system (100) determines that a change in designation is necessary, but that changing the designation for one or more operators (102) would violate a restriction, then the designation system (100) can designate one or more other operators (102) to the vehicle system (104), or it may not change the designation of the operator (s) (102) to the vehicle system (104).
[074] Figure 4 illustrates an embodiment of the designation system (100). The designation system (100) includes one or more
Petition 870190039552, of 04/26/2019, p. 210/339
42/136 processors (400) (for example, one or more microprocessors, one or more arrays of field programmable ports and / or one or more integrated circuits) that perform the functions that are described here as being performed by the designation system ( 100). Processors (400) can receive input and / or output to one or more users of the designation system (100) through one or more input and / or output devices (402) (“I / O Devices” in Figure 4 ). Input / output devices (402) can represent one or more electronic monitors, touch screens, keyboards, electronic mice, digital pens (styluses), microphones, speakers, etc.
[075] The designation system (100) includes a communication system (404) that allows processors (400) to communicate with one or more other systems or devices. The communication system (404) can include one or more transceivers, transmitters, receivers, modulators, routers, antennas or the like, which allow processors (400) to communicate with vehicle systems (104) and with one or more sources of memory. The memory sources shown in Figure 4 are provided as an example, and a different combination of memory sources can be used. The memory sources shown in Figure 4 can represent tangible, non-transitory, computer-readable media, such as computer hard drives, servers, USB memory, optical drives, etc.
[076] The memory sources can include a local memory (406) that stores information in the designation system (100), such as which operators (102) are assigned to which vehicle systems (104), which operators (102) are available, operator personnel needs, vehicle system schedules (104), operator qualifications, limits or restrictions on which operators (102) can be assigned to
Petition 870190039552, of 04/26/2019, p. 211/339
43/136 different vehicle systems (104), and the like.
[077] Memory sources can include a travel database (408) that stores travel data. The trip data includes information on the load carried by the different vehicle systems (104), the schedules of the vehicle systems (104), the locations of the vehicle systems (104), and / or vehicle identifications in the vehicle systems ( 104). Processors (400) can obtain at least some of this information to assist in assigning operators (102) to vehicle systems (104), as described above.
[078] The memory sources can include a route database (410) that stores route data. The route data includes information about the routes (202) on which the vehicle systems (104) travel or will travel. This information can include identification of curves in the routes (202), ripples in the routes (202), speed limits of the routes (202), degrees in the routes (202), traffic congestion (historical and / or expected for the next times) in different areas, locations of routes (202), areas of routes (202) that are under maintenance or other repair, and the like. Memory sources can include a weather database (412) that stores weather data. Climate data includes predicted weather forecasts, historical weather conditions and the like, for one or more areas through which the routes (202) extend.
[079] Memory sources can include a labor database (414) that stores labor data. Labor data includes information about operators (102), such as training completed by multiple operators (102), operator experiences (102), restrictions on which vehicle systems (104) can be assigned to some operators (102 ), special operator qualifications (102), operator working hours (102), indications of how long the operators
Petition 870190039552, of 04/26/2019, p. 212/339
44/136 (102) have been working continuously to remotely control and / or monitor vehicle systems (104), and the like.
[080] The designation system (100) optionally includes one or more sensors (416) that can generate data indicative of how alert or fatigued operators (102) are. The sensors (416) can represent cameras that generate images or videos of the operators (102) (which can be inspected manually and / or automatically to check the operator's agility or fatigue (102)), an input / output device that provides questions , games or other interactive exercises to test and / or increase the agility of operators (102) or something like that.
[081] Figures 5A to 5C illustrate a flow chart of an embodiment of a method (500) to dynamically designate operators to remotely control and / or monitor movements of one or more vehicle systems. The method (500) can represent the operations performed by the processors (400) of the designation system (100) in one embodiment. In (502), vehicle systems (104) are identified that must be controlled and / or monitored remotely during the next trips. These vehicle systems (104) can be identified by determining which vehicle systems (104) are scheduled to depart on trips within a designated period of time (for example, a working day), determining which vehicle systems (104) are associated with a subscription or purchase of a service to remotely control and / or monitor the movement of vehicle systems (104), examining travel data from vehicle systems (104), or the like.
[082] In (504), the next trips of the vehicle systems (104) are determined. These trips can be determined by examining trip data from vehicle systems (104). These data can indicate where the vehicle systems (104) are departing from, where the
Petition 870190039552, of 04/26/2019, p. 213/339
45/136 vehicles (104) are traveling and / or where the vehicle systems (104) are driving. Optionally, this information can be provided by an operator on board a vehicle system (104), or it can be obtained from global positioning system data (or other location data) received from a vehicle system (104). For example, processors (400) can track where a vehicle system (104) is moving based on data received from the vehicle system (104). The next trip for that vehicle system (104) can be routes (202) to which the vehicle system (104) is directed, even if the trip of the vehicle system (104) has not yet been planned.
[083] In (506), the risks to the safe travel of vehicle systems (104) in the next trips are identified. As described above, these risks may include the transport of dangerous cargo, travel through dangerous or difficult sections of a route (202), travel through dangerous weather conditions, travel through congested traffic areas and the like. The risks that are identified can include static risks and / or time-varying risks, also as described above.
[084] In (508), time-varying risk profiles for vehicle systems are determined based on the identified risks. As described above, these profiles (304) can represent how the risks to the safe travel of vehicle systems (104) increase or decrease over time. In (510), a demand for operator personnel is determined based on risk profiles. Demand for operator personnel can be determined by calculating how many operators (102) are required to remotely control and / or monitor vehicle systems (104) based on risk profiles (304) to achieve an acceptable global risk (for example, below any total risk threshold). This acceptable risk limit can vary based on a risk tolerance. For example, thresholds
Petition 870190039552, of 04/26/2019, p. 214/339
46/136 higher can be associated with systems (100) having increased risk tolerances, while lower thresholds can be associated with systems (100) having reduced risk tolerances. A risk tolerance can depend on a variety of factors, such as an insurance provider's restrictions or limitations on the insurable operation of the system (100), a risk tolerance requested by the subscriber, or the like. As described above, increased risk profiles (304) may require more operators (102), while reduced risk profiles (304) may require fewer operators (102).
[085] In (512), it is determined whether one or more vehicle systems require special operator qualifications. This determination may involve determining whether one or more vehicle systems (104) are traveling or will be traveling along dangerous route conditions, are traveling or will be traveling in dangerous climatic conditions, are carrying dangerous cargo and the like, as described above. These conditions may indicate that an operator (102) having specialized qualifications to control and / or monitor the vehicle system (104) may be required to assign the vehicle system (104) associated with the risks that require specialized qualification.
[086] If a vehicle system (104) is associated with a risk requiring specialized operator qualification, then the flow of the method (500) can proceed towards (514). Otherwise, the flow of the method (500) can proceed towards (516).
[087] In (514), an operator with a specialized qualification that is required by a vehicle system is assigned to that vehicle system. For example, an operator (102) having specialized training and / or experience in remotely controlling the movement of a vehicle system (104) that carries dangerous cargo or that includes a
Petition 870190039552, of 04/26/2019, p. 215/339
47/136 vehicle with specialized handling rules, can be assigned to a vehicle system (104) that is carrying that dangerous load or that includes that vehicle, as described above.
[088] In (516), potential operator designations for vehicle systems are examined. These potential designations can be determined by designating operators (102) having specialized qualifications for vehicle systems (104) that require such qualifications, and then assigning the remaining operators (102) to vehicle systems (104) based on risk profiles (304) of the vehicle systems (104). As described above, more operators (102) can be assigned to vehicle systems (104) with higher risk profiles (304), while fewer operators (102) can be assigned to vehicle systems (104) with lower risk profiles ( 304). Potential designations can be examined to determine whether the designations violate any limits.
[089] In (518), a determination is made as to whether examination of the potential operator designations indicates that a designation violates one or more limits. As described above, processors (400) can limit how many vehicle systems (104) an operator (102) can be assigned, can limit which operators (102) can be assigned to a vehicle system (104) based on qualifications operators (102), can limit how long operators (102) can be working to remotely control and / or monitor vehicle systems (104), etc. Processors (400) can examine potential designations and determine whether any designations violate a threshold. If a designation violates a limit, then the flow of the method (500) can proceed to (520). Otherwise, the flow of the method (500) can proceed to (522).
[090] In (520), a designation of one or more operators for one or more vehicle systems is changed. The operator (102) who was
Petition 870190039552, of 04/26/2019, p. 216/339
48/136 assigned or potentially assigned to a vehicle system (104) in violation of a limit can be re-assigned to another vehicle system (104). The reassignment of operators (102) may be subject to one or more additional limits, as described herein, such as not to reassign an operator (102) frequently or to too many vehicle systems (104).
[091] In (522), operators are assigned to vehicle systems according to potential designations. For example, those operator designations that do not violate the limit (s) can be assigned to vehicle systems. As described above, this designation may involve the machine (106) used by the operator (102) by establishing a communication link with the vehicle system (s) (104) to which the operator (102) ) is designated. Optionally, the operations described in connection with (510) to (522) can be performed in a single integrated operational step, solving a single optimization problem that takes into account the various factors and restrictions described above.
[092] In (524), vehicle systems are controlled and / or monitored remotely using instructions that are sent from designated operators. Vehicle systems (104) can change acceleration settings, speeds, brake settings and the like, based on instructions received from operators (102) who are located remotely. Operators (102) can be located remotely, as operators (102) are unable to see vehicle systems (104) being controlled by operators (102) without the aid of a camera and a viewfinder that shows images or video generated by the camera.
[093] In (526), a determination is made as to whether the risk profile for one or more of the vehicle systems changes during the travel of the vehicle systems. The risk profile (304) for a vehicle system (104) can change for a variety of reasons, such as route maintenance
Petition 870190039552, of 04/26/2019, p. 217/339
49/136 unknown or unplanned, a change in weather conditions, a change in route conditions, a change in traffic congestion, an accident or failure involving the vehicle system (104) and so on. If the risk profile (304) for a vehicle system (104) changes (for example, increasing), then one or more additional operators (102) may need to be assigned to the vehicle system (104) and / or one or more operators (102) having specialized qualifications may need to be assigned to the vehicle system (104). As a result, the flow of method (500) can proceed in the direction of (528). Otherwise, the method flow (500) can proceed to (530).
[094] In (528), one or more different and / or additional operators are assigned to the vehicle system. The increased and / or different risk associated with the vehicle system (104) may require that more operators (102) are involved in the control and / or monitoring of the vehicle system (104), and / or that an operator (102) having a specialized qualification control and / or monitor the vehicle system (104). One or more of these additional and / or specially qualified operators (102) can be assigned or reassigned to the vehicle system (104).
[095] In (530), it is determined whether an operator designation needs to be changed for any of the vehicle systems. An operator designation may have to be changed if operator (102) is working or will finish working longer than a designated limit, if an operator (102) requests a change in designation, if an operator (102) becomes fatigued or something similar. If an operator assignment requires a change, then the method flow (500) can proceed to (532). Otherwise, the method flow (500) may return to (524). Alternatively, the flow of method (500) may return to another operation or may terminate.
Petition 870190039552, of 04/26/2019, p. 218/339
50/136 [096] In (532), one or more different operators are assigned to the vehicle system. For example, if an operator (102) has worked long hours to remotely control a vehicle system (104), if the operator (102) requests a different designation from another vehicle system (104), if the operator (102) requests a pause for some other reason, if the operator on board (102) or passengers (120) request dedicated assistance that requires a re-designation, and / or the operator (102) has become fatigued, then an additional and / or replacement (102) can be assigned to that vehicle system (104). The method flow (500) can then return to (524). Alternatively, the flow of method (500) may return to another operation or may terminate.
[097] In one embodiment, a method includes determining time-varying risk profiles for multiple separate vehicle systems that are remotely controlled by operators that are located outside the separate vehicle systems. Time-varying risk profiles represent one or more risks to the path of separate vehicle systems during travel of separate vehicle systems that change with respect to time during travel of separate vehicle systems. The method also optionally includes determining a demand for operator personnel for vehicle systems based on the time-varying risk profiles of separate vehicle systems. The demand for operator personnel represents how many of the operators are required to remotely control separate vehicle systems at different times during travel and a required qualification of one or more operators to remotely control separate vehicle systems at different times during travel. The method also includes designating operators to remotely monitor or control separate vehicle systems while traveling, based on
Petition 870190039552, of 04/26/2019, p. 219/339
51/136 in time-varying risk profiles and, optionally, based on the demand for operator personnel. The operator assigned to one or more of the separate vehicle systems changes over time during the journey of the one or more separate vehicle systems, while the one or more separate vehicle systems is moving along one or more routes during the travel.
[098] Optionally, the method includes remotely controlling the movement of at least one of the separate vehicle systems based on instructions received from at least one of the operators assigned to at least one of the separate vehicle systems, and / or remotely monitoring the operation of at least one of the separate vehicle systems based on instructions received from at least one of the operators assigned to at least one of the separate vehicle systems.
[099] Optionally, separate vehicle systems include separate railway vehicle systems.
[0100] Optionally, separate vehicle systems include separate cars.
[0101] Optionally, separate vehicle systems include separate trucks.
[0102] Optionally, separate vehicle systems include separate marine vessels.
[0103] Optionally, separate vehicle systems include separate aerial vehicles.
[0104] Optionally, separate vehicle systems include separate unmanned aerial vehicles.
[0105] Optionally, separate vehicle systems include vehicles that travel or programmed for one or more routes on different routes, travel in different directions or travel in locations
Petition 870190039552, of 04/26/2019, p. 220/339

[0144] Figure 6 illustrates an embodiment of a distributed control system (600). The distributed control system is distributed in such a way that multiple operators (102) (for example, (102A-C)) located in multiple, different and remote locations are able to work on control operations and / or systems monitoring operations of multiple separate vehicles (104) (e.g. (104A-C)). Operators can be in remote locations when at least one of the operators is outside the vehicle system being controlled, with those operators simultaneously controlling the operations of the same vehicle system. For example, the operator (102A) may be located on board the vehicle system (102A) to locally control the operations of the vehicle system (102A) and another operator may be located outside the vehicle system (102A) to control one or more of the same or different operations of the same vehicle system (102A). Vehicle systems can be separated when vehicle systems are not mechanically coupled with each other and are not traveling with each other. The vehicle systems described here can include a variety of different
Petition 870190039552, of 04/26/2019, p. 228/339
60/136 types of vehicles. For example, vehicle systems can include rail vehicle systems (for example, trains), automobiles, marine vessels, aircraft (for example, drones), etc. and can be manned by one or more operators or unmanned (ie more autonomous). Although vehicle systems are illustrated as trains, not all embodiments can be limited to trains. Vehicle systems are not model or toy vehicles in at least one embodiment of the object matter described here.
[0145] In one embodiment, the distributed control system includes a highly automated vehicle control system (not shown in Figure 1) that is optionally manned by at least one operator on board the vehicle system (also referred to as a local or onboard crew member) and a remote control system or station (106) that supports another operator (also referred to as a remote or external crew member). Alternatively, the vehicle system can be controlled by remote and local control systems without any human operator on board the vehicle system. The remote crew member can use the remote station to control the operations of multiple vehicle systems. For example, the remote crew member can use the remote station to switch between control operations for different vehicle systems at different times and / or control operations for two or more vehicle systems at the same time.
[0146] Vehicle and remote control systems are communicatively coupled by one or more networks. These networks can be wireless networks, such as networks that communicate signals between devices or wireless communication networks (110), such as antennas, satellites, routers, etc. The remote crew member or operator can monitor and / or control the operations of the vehicle systems through signals communicated between the
Petition 870190039552, of 04/26/2019, p. 229/339
61/136 vehicle control system and the remote control system through the communication devices.
[0147] In one embodiment, communication devices can provide much longer intervals for controlling vehicle systems than land-based wireless communication devices. For example, communication devices can allow a remote control system to remotely communicate and control vehicle systems over a range of hundreds or thousands of kilometers from the devices and the remote control system. Communication devices may include satellites or devices that communicate with satellites (for example, antennas and associated transceiver circuits) that allow wireless signal communication between vehicle systems and the remote control system over large distances of hundreds or thousands of miles or kilometers. This allows the remote operator to remotely control the movement of a vehicle system without the vehicle system being within the view (for example, the view range) of the remote operator (without the use of a camera or magnifying device).
[0148] The remote operator can control different vehicle systems at different times. For example, for a first period of time, the remote operator can have the remote control system generate and communicate signals to the vehicle control system of the vehicle system (104A) to control operations (for example, to change or control an acceleration position) of the vehicle system (104A). During a subsequent second period of time, the remote operator can have the remote control system generate and communicate signals to the vehicle control system of the vehicle system (104B) to control operations (for example, to change or control a position accelerator) of the vehicle system (104B). The remote operator and the remote control system can
Petition 870190039552, of 04/26/2019, p. 230/339
62/136 continue to switch between which vehicle system is controlled for different periods of time to allow the remote operator to simultaneously control the operations of several different vehicle systems. Optionally, the remote operator and the remote control system can communicate signals to multiple vehicle systems at the same time or for overlapping periods of time, in order to simultaneously control the operations of multiple vehicle systems. The remote control system can control the movements of these vehicle systems in a road environment. For example, instead of the remote control system controlling only the movement of vehicle systems within a vehicle yard (for example, a railway yard), the remote control system can control the movement of vehicle systems over time. routes that extend between vehicle yards or that are much larger (for example, longer) than vehicle yards.
[0149] The remote control system can remotely control movements of different vehicle systems based on the conditions of the routes on which the vehicle systems are moving. For example, the remote control system can remotely control the movement of a vehicle system while that vehicle system is traveling a first segment of the route that has fewer turns and / or has turns with greater radius of curvature than a different second segment of the route. In response to the vehicle system traveling on the second leg of the route, the remote control system can pass or transfer control of the vehicle system to an operator on board.
[0150] Vehicle control systems on board vehicle systems can control the same or other operations of vehicle systems as remote control systems. For example, in one embodiment, the remote control system can control the
Petition 870190039552, of 04/26/2019, p. 231/339
63/136 acceleration or speed of a vehicle system during rated conditions and the operator on board the same vehicle system can monitor the vehicle system and change the throttle configuration, apply the brakes, or control the operation of the vehicle system in response to the identification of an unsafe situation (for example, the vehicle system moving too fast, an obstruction in the route being traveled by the vehicle system, etc.). Optionally, the remote control system can control or alter the operation of the vehicle system in response to the identification of an unsafe situation (for example, the vehicle system moving too fast, an obstruction in the route being traveled by the vehicle system, etc. .).
[0151] Figure 7 illustrates an embodiment of a vehicle control system (700). The vehicle control system is arranged on board the vehicle system. While the vehicle system is shown as a single vehicle in Figure 7, optionally, the vehicle system can include multiple vehicles traveling together along a route. Vehicles in a vehicle system can be mechanically coupled with each other or they can be mechanically decoupled or separated from each other, but communicating with each other to coordinate the movements of vehicles, such that vehicles travel together as a vehicle system bigger.
[0152] The vehicle control system includes a controller (702), which represents a hardware circuit that includes and / or is connected to one or more processors (for example, microprocessors, controllers, field programmable port arrays and / or integrated circuits) that perform various operations described here. The controller receives signals from an input device (704) that receives control input from the operator on board the vehicle system. The input device can represent one or more regulating valves (for example, levers, pedals, etc.), buttons, touch screens, switches, etc., which control the operation of the
Petition 870190039552, of 04/26/2019, p. 232/339
64/136 vehicle system. For example, the input device can be triggered by the operator on board the vehicle system to change the throttle setting of a propulsion system (706) to change how quickly the vehicle system is moving, to change a setting brake of a brake system (708), to communicate one or more signals to the remote control system (for example, via a communication device (710) of the vehicle control system), or to control in another way the operation of the vehicle system.
[0153] The propulsion system represents one or more engines, generators, alternators, mechanisms or the like, which operate to propel the vehicle system. The brake system represents one or more vehicle system brakes, such as dynamic brakes, friction brakes, etc. The communication device represents the hardware circuits used to communicate signals with the remote control system, such as one or more antennas, transceivers, routers or the like. An output device (712) can present information to the operator on board, such as information representative of vehicle system operations (for example, movement speeds, speed limits, accelerations, temperatures, fuel levels, etc.), information communications from the remote control system (for example, speeds at which the vehicle system should move, places where the vehicle system should brake, etc.) or other information. The output device can represent one or more touch screens (which can also be the input device) or other display devices, speakers, haptics, etc.
[0154] In an operating mode, the vehicle control system receives control inputs from the remote control system and uses the control inputs to automatically control the operation of the vehicle system. Control inputs can designate operations or settings
Petition 870190039552, of 04/26/2019, p. 233/339
65/136 operating or vehicle system parameters, such as the designated speeds at which the vehicle system must travel, designated times and / or locations at which the vehicle system should brake, designated accelerations and / or decelerations at which the system vehicle must change speed, locations where the vehicle system should move, designated acceleration settings, etc. The vehicle control system controller can receive these control inputs from the remote control system via the vehicle system communication device and automatically control (for example, without operator intervention on board) the propulsion system and / or brake system of the vehicle system to implement the control inputs.
[0155] The remote control of the vehicle system can give the crew member on board or location more time to concentrate on other tasks (related to the crew member on board or location that does not have the remote control system available to assist in the control of the vehicle system movement). For example, the operator on board may have additional time to search for obstructions in the vehicle system's path of travel, monitor vehicle system operation, perform vehicle system maintenance, inspection and / or repair or the like. The system can reduce the ability to manually control the movement of the vehicle system, such as by having the remote control system providing speed inputs and the vehicle control system being used by the operator to control the vehicle system for driving. according to the speed inputs.
[0156] For example, the remote control system can communicate speed reference points, or designated speeds (and / or locations along a route, distances along a route or times at which the vehicle system must travel as designated speeds) when
Petition 870190039552, of 04/26/2019, p. 234/339
66/136 vehicle control system. These speeds can be provided to the vehicle control system as the vehicle control system is moving, in contrast to a previously determined or generated speed or time path that is generated before the vehicle system moves. The vehicle control system can receive and report these speeds to the operator on board, and the operator on board can activate the vehicle system's onboard input device to cause the vehicle system to move according to the speeds designated. In addition, the operator on board can safely and efficiently return to controlling the movement of the vehicle system if necessary, providing a speed input to the local control system, such as when the operator in the remote control system is unable to steer Remotely moving the vehicle system, communication delays or interruptions prevent the remote control system from communicating control inputs to the vehicle control system, etc.
[0157] The vehicle control system controller includes specialized driving knowledge that incorporates vehicle handling and other information used to determine how to change operational settings (for example, acceleration and / or brake settings) of the vehicle system to safely and efficiently control the vehicle system according to the higher order control inputs provided by the remote control system. For example, the controller can receive operational reference points as control inputs from the remote control system and / or the operator on board. An operational reference point can represent an operational goal that the vehicle system must achieve, such as a speed of movement, a location or distance at which the vehicle system must stop or delay movement, a location for which the vehicle must travel, a time during which the vehicle system
Petition 870190039552, of 04/26/2019, p. 235/339
67/136 must reach a location, an amount of fuel that the vehicle system must consume or consume less than during movement, an amount of emissions that the vehicle system must generate or generate less than during movement, configurations or acceleration positions, brake settings or positions, etc. The vehicle control system receives the operational reference points and changes the settings of the propulsion system and / or the brake system of the vehicle system so that the vehicle system reaches the reference points.
[0158] As an example, the vehicle control system can receive a designated speed at which the vehicle system must travel from the operator on board and / or the remote control system. The vehicle control system controller can determine a current vehicle system speed (for example, from a sensor such as a tachometer, global positioning system receiver, etc.) and compare current and designated speeds to determine how to change the acceleration and / or brake settings of the vehicle system to achieve the designated speed. In one example, the controller can determine changes to the acceleration and / or brake settings that cause the vehicle system to reach the designated speed while consuming less fuel and / or generating less emissions than using other different changes to the acceleration settings and / or brake (for example, changing to the highest acceleration setting). In another example, the controller can determine changes that reduce the number and / or size of the acceleration and / or brake configuration changes compared to other changes, changes in the acceleration and / or brake settings that reduce the forces exerted on the couplers in relation to other changes etc.
[0159] The controller can control the propulsion systems and /
Petition 870190039552, of 04/26/2019, p. 236/339
68/136 or braking to attempt and maintain, on average, the designated reference point and / or use the reference point as an upper limit in the vehicle system's operational settings. The controller can project the speeds at which the vehicle system will move (for example, determining a speed trajectory) based on the current speed and changes in acceleration and / or brake settings to determine how to make the vehicle system travel at the reference point designated by the remote control system or the operator on board.
[0160] The remote control system can dictate control inputs that control the operation of the vehicle system at various levels. For example, the remote operator can use the remote control system to provide variable speed reference points during a trip of the vehicle system, depending on the locations of the vehicle system, such that the reference points change in two or more different locations. For example, landmarks can be communicated to the vehicle control system from the remote control system such as: proceed on time (0530), stop on site (123) for time (1400); place the wagon on the diversion (with guards and entrances provided by the crew member on board; stop at location (53) until authorized to move by the section chief. A simple language / syntax can be developed to provide these reference points. The vehicle control system controller then transforms these reference points into a speed command path, which is used to determine the vehicle system's propulsion and braking system configurations.
[0161] The vehicle control system can receive the operational reference points and determine an operational configuration path for a vehicle system based on the operational reference points. For example, the controller can receive reference points
Petition 870190039552, of 04/26/2019, p. 237/339
69/136 speed provided by the remote control system and determine the acceleration settings and / or brake settings that must be used by the respective propulsion and braking systems in order for the vehicle system to reach the speed reference points. The controller can examine route degrees, route curvatures, vehicle and / or load weights, etc., to determine acceleration and / or brake settings. For example, for steep grades and / or heavier vehicles and loads, higher acceleration settings may be needed to accelerate to a faster speed reference point than for lower or flatter grades and / or lighter vehicles and loads. The acceleration and / or brake settings can be assigned to different locations along the route, distances along the route and / or times. The controller can then control the propulsion and / or braking systems to implement the acceleration and / or braking settings in order to reach the speed reference points.
[0162] Optionally, the vehicle control system and / or the operator on board the vehicle system can determine the reference points of the vehicle system and communicate these reference points to the remote control system via the communication device. The remote control system can examine the reference points and determine the operational settings and / or changes in the vehicle system's operational settings that can be used to reach or reach the reference points. Operational settings and / or changes to operational settings can be communicated from the remote control system to the vehicle control system so that the vehicle control system controller can implement the operational settings and / or changes to the operational settings with the systems propulsion and / or braking.

70/136 [0163] A vehicle control system (714) warning system monitors the operator's physiological characteristics on board the vehicle system to determine whether the operator on board is alert and able to provide sufficient protection against unsafe operation of the vehicle. vehicle system by the onboard controller and / or the remote control system. The alert system receives monitoring signals from one or more sensors in a sensor array (716). These sensors can include heart rate monitors, blood pressure monitors, chambers, the input device (204), etc. The alert system includes or represents a hardware circuit that includes and / or is connected to one or more processors (for example, microprocessors, field programmable port arrays or integrated circuits) that receive and examine the monitoring signals from the array of sensors. Based on the monitoring signals, the alert system can determine whether the operator on board the vehicle system is alert and monitoring the operations of the vehicle system.
[0164] For example, the alert system can examine the operator's blood pressure and / or pulse or heart rate and rate of change to determine if the operator is alive and alert. Optionally, the alert system can examine other sensor data, such as electroencephalogram (EEG) data, electrocardiogram (ECG) data or other contact / wearable measurements from the operator. The alert system can receive images or video from the operator to determine if the operator is moving at least as many times as a designated frequency (for example, once every minute, once every hour, etc.). The alert system can receive images or videos from the operator and use computer or mechanical vision techniques to determine the operator's postures and / or gestures, such as being tilted versus erect, raised eyebrows or closed eyes, yawns or closed mouths , etc., to determine if the operator is
Petition 870190039552, of 04/26/2019, p. 239/339
71/136 alert.
[0165] As another example, the alert system provides cognitive tasks to the operator (for example, via the output device) and examines the performance of tasks by the operator to determine whether the operator is alert. Cognitive tasks can include instructions for playing a game (for example, tic-tac-toe), instructions for performing a series of vehicle system scans, instructions for activating a sequence of input devices (for example, buttons, levers, touchscreen areas, etc.) or other tasks that require the operator to be alert to perform tasks. If the operator does not complete tasks with at least a specific level of achievement or is unable to complete tasks, then the alert system can determine that the operator is not alert. Optionally, cognitive tasks can be contextual cognitive tasks. These tasks may be similar to the cognitive tasks described earlier, but may require the operator to perform tasks related to the operation of the vehicle system. For example, the alert system can direct the operator to manually enter (via input device) the current location of the vehicle system, the current ambient temperature, the current weather conditions, the degree of the route segment currently being traveled, and so on. onwards. If the operator is unable to complete the task and / or perform the task to at least a designated level (for example, the operator is unable to finish a game or is unable to win the game), then the alert system can determine that the operator is not currently alert.
[0166] In one embodiment, the alert system contextually examines the behavior of the observed operator (for example, inputs to the local control system) for the expected behavior of the operator generated through an awareness of the vehicle context. Per
Petition 870190039552, of 04/26/2019, p. 240/339
72/136 example, the warning system can determine when the vehicle system is approaching a level crossing and that the expected behavior is for the operator to be attentive to the intersection and place a hand on or near a car horn driver. vehicle system. If the operator does not behave in this way, the alert system will then determine that the operator is not alert.
[0167] In response to the determination that the operator is not alert, the alert system can take one or more actions. The alert system can activate one or more alarms (eg lights, speakers, etc.) via the output device, the alert system can direct the controller to automatically reduce the throttle and / or activate the braking system of the vehicle system, the alert system can communicate a warning signal to the remote control system, the alert system can change control of one or more operations of the vehicle system from the operator on board or vehicle control system to the remote operator or remote control system (for example, control over the braking system), etc.
[0168] Optionally, the alert system can monitor the physiological characteristics of an external operator in the remote control system to determine whether the external operator is present and alert during remote control of one or more vehicle systems. In response to the determination that the external operator is not present or is not alert, the alert system can pass or transfer remote control from one vehicle system to another remote operator or to an operator on board the vehicle system.
[0169] In one embodiment, the communication devices and / or controllers can monitor the communication or data link (s) between the communication devices to determine whether
Petition 870190039552, of 04/26/2019, p. 241/339
73/136 must change how the vehicle system is controlled based on communication or data connection (s). A communication or data link can represent a connection between the communication devices to allow data communication between the communication devices. The connection can be broken or interrupted due to a variety of causes, such as failure of a communication device, route of the vehicle system through a tunnel or valley, electromagnetic interference from sources external to the vehicle system, etc. Communication or data connection between the remote control system and the vehicle system can be monitored by the communication devices and, if the connection is interrupted, destroyed or very limited (for example, the bandwidth or speed of the connection decreases below of a designated limit, such as decreasing by 50% or more), then the communication devices and / or controllers can designate another remote control system to control and be communicatively coupled to the vehicle system.
[0170] The vehicle control system also includes a crew resource management unit (CRM) or console (718). With the vehicle system being controlled using a distributed crew of operators, the CRM unit (718) provides non-verbal communication between remote and local operators of the vehicle system. The CRM unit represents a hardware circuit that includes and / or is connected to one or more processors (for example, microprocessors, integrated circuits, field programmable port arrays, etc.) that receive signals from the remote operator through the control system remote and communication device, the operator on board via the input device, the alert system, a remote control system alert system and / or one or more other locations, and displays or presents this information to the operator on board the vehicle system. For example, if the operator on board
Petition 870190039552, of 04/26/2019, p. 242/339
74/136 or remote updates the speed or status of the vehicle system, an indicator light can be activated on the CRM unit, which notifies other operators of the updated speed or status. The CRM unit may require the operator at the same location as the CRM unit to confirm or acknowledge the speed or changed state, for example, by triggering the input device. This recognition can be communicated to operators (local and remote) to ensure that all operators are aware of changes in vehicle system operations and are aware that other operators are aware of the changes.
[0171] Figure 8 illustrates another embodiment of the remote control system (106). The remote control system includes a communication device (810), which can be similar or identical to the vehicle control system's communication device, to allow the remote and vehicle control systems to communicate with each other. The remote control system also includes a controller (802), which can be similar or identical to the controller (202) of the vehicle control system. The controller (802) can perform the operations of the remote control system described here. The remote control system can also include an alert system (814) and an array of sensors (816) that operate and perform the same functions or the like, as described above, in connection with the same components as the vehicle control system. . This allows the remote control system to determine whether the remote operator in the remote control system is alert. The remote control system also includes an output device (812) similar or identical to the output device (812) of the vehicle control system, and a CRM unit (818) that is identical or similar to the CRM unit (818) of the vehicle control system.
[0172] The remote control system can allow a single remote operator to remotely control the operations of multiple control systems
Petition 870190039552, of 04/26/2019, p. 243/339
75/136 vehicles and maintain awareness of other relevant vehicle systems. The remote control system controller can generate signals for display on the output device to represent current states of various vehicle systems. The operator or remote controller can select a vehicle system to be controlled, and the remote operator can change one or more of the operating settings of the selected vehicle system via the remote control system's input device, such as by setting a reference point for the vehicle system. The remote control system controller can then generate a signal representative of the reference point for communication with the vehicle control system controller to allow the vehicle system to be controlled. The remote control system and / or the remote operator can switch between controlling several different vehicle systems at different times or allowing the operator to control multiple vehicle systems at the same time.
[0173] The remote operator can have access to significantly more information about the context of the vehicle systems being controlled by the remote control system than any single local operator of a vehicle system in one embodiment. As the remote control system can communicate with several vehicle systems at a time, the data representing the states of these vehicle systems can be aggregated and presented to the remote operator by the CRM unit (818) via the output device (812). These data include current locations, speeds and states of vehicle systems and crew members in vehicle systems (for example, the controller, alert system, CRM unit or other data source), the location of each vehicle system in relation to each other and other crossing points, and physical aspects of the region of operation (for example, network switch states, dispatcher signals, maintenance areas, slippery areas, etc.).
Petition 870190039552, of 04/26/2019, p. 244/339
76/136 [0174] Figure 9 illustrates an example of information presented to an operator of the remote control system and / or vehicle of the corresponding remote control system and / or vehicle. The information shown in Figure 9 can be presented on the output device, such as a display, to the operator. This information shows an elevation map (900) of the route being traveled by one or more vehicle systems, along with stop locations and other relevant waypoints along the elevation map (900), vehicle system locations and directions route of the vehicle systems indicated on or near the elevation map (900) (for example, by the arrowhead of the symbols representing the vehicle systems).
[0175] A network status representation (902) can be presented to the operator to indicate the current and future states of the vehicle systems, as estimated or predicted by the remote control system controller based on the current states of the vehicle systems. The state representation (902) is shown next to a horizontal axis (904) representing time and a vertical axis (906) representing different locations along a selected route being traveled by different vehicle systems. In the illustrated embodiment, several solid lines (906) indicate alternate or detour route locations that a vehicle system can move to leave the route shown on the map (900) and allow another vehicle system to pass the route. Several programmed movement lines (908) (for example, movement lines (908A-C)) represent estimated, programmed or predicted movements of various vehicle systems.
[0176] For example, a movement line (908A) can represent the movement of a first vehicle system (106A) along a route (910), a movement line (908B) can represent the movement of a second system vehicle along route (910), and a line of
Petition 870190039552, of 04/26/2019, p. 245/339
77/136 movement (908C) can represent the movement of a third vehicle system along the route (910). This information presented to the operator by the exit device may indicate that the vehicle system is programmed to travel in a first direction of travel along route (910) without stopping or leaving any detour routes, while the second vehicle system must travel in an opposite direction of travel along the same route (910) for a detour represented by the route line (906A), exit route (910) for the detour (906A) and wait for a designated period of time (912), retreat on route (910) and move to another detour represented by the route line (906B), exit route (910) to detour (906B) and wait for a designated period of time (914), and retreat to the route (910) and travel along route (910). This information also indicates that the vehicle system is programmed to travel in the same direction of travel along route (910) as the second vehicle system, but at a later time, and to exit route (910) on a detour ( 906C) and wait for a designated period of time (916), retreat to route (910) and move to detour (906B), exit route (910) to detour (906B) and wait for a period of designated time (918), and go back to route (910) and travel along route (910).
[0177] The remote operator can be assigned to control the movement of vehicle systems traveling along a designated section of the route (910), as the part of the route (910) shown in Figure 9. Responding to a vehicle system entering the section of the route being controlled by a remote operator, the vehicle system can begin to be controlled by that remote operator. Before the vehicle system enters this section of the route and after the vehicle system leaves this section of the route, the vehicle system can be controlled by other remote operators. The remote operator in charge of controlling vehicle systems throughout the
Petition 870190039552, of 04/26/2019, p. 246/339
78/136 section of the route can concurrently or simultaneously control the movements of the vehicle systems while those vehicle systems are in the section of the route.
[0178] Figure 10 illustrates another example of information presented to an operator of the remote control and / or vehicle system described here by the corresponding output device. The information shown in Figure 10 is an updated version of the information shown in Figure 9. For example, as vehicle systems move along the route (910), the CRM unit can update and display the actual locations of the vehicle systems while along the route as completed movement lines (1008) (for example, movement lines (1008A-C)).
[0179] The differences (1020, 1022) between the planned or programmed movement lines (908) and the actual movement lines (1008) can indicate vehicle systems moving ahead or behind. For example, the difference (1020) may indicate that the first vehicle system is moving late along the route (910) and the difference (1022) may indicate that the third vehicle system is moving along the route (910 ) even later. This change in information can provide quickly discernible updates on vehicle system locations to the remote operator who is controlling the movement of vehicle systems. The operator can change the way vehicle systems are controlled based on the information shown by the output device, such as increasing the speed reference points of the first and third vehicle systems and / or extending the time period (916) that the third vehicle system remains on the deviation (906C).
[0180] Figure 11 illustrates another example of information presented to an operator of the remote control and / or vehicle system described here by the corresponding output device. The information shown
Petition 870190039552, of 04/26/2019, p. 247/339
79/136 in Figure 11 is an updated version of the information shown in Figure 10. For example, as weather conditions change, graphical weather indicators (1100) can be covered or otherwise shown on the output device. In the illustrated embodiment, climate indicators can represent when and where precipitation (for example, rain, ice and / or snow) is expected to occur, as well as information provided by meteorologists or other sources. The location of weather indicators can visually inform the remote operator when and where weather conditions can affect the movement of vehicle systems. In response to observing the weather indicators, the operator can change the way one or more of the vehicle systems are controlled, such as decreasing the movement of the vehicle systems, increasing the braking distances of the vehicle systems, etc.
[0181] Figure 12 illustrates another example of information presented to an operator of the remote control and / or vehicle system described here by the corresponding output device. The information shown in Figure 12 represents at least some of the monitoring information obtained by the alert system from one or more of the remote control systems and / or the vehicle and presented to one or more operators via the output device to allow operators external (and, optionally, on-board) vehicle systems to monitor vehicle system operations and the agility of operators on board vehicle systems.
[0182] An operational configuration chart (1200) shows vehicle system configurations at different times. This graphic (1200) can illustrate, for example, a configuration (1210) of the vehicle system's braking system (for example, the position of an aerodynamic brake lever), an air pressure (1212) in the vehicle's braking system
Petition 870190039552, of 04/26/2019, p. 248/339
80/136 vehicle system, a position (1214) of an individual vehicle brake in the vehicle system and / or other information. The information shown in the graph (1200) can be obtained and / or provided by the controller and / or CRM unit of the vehicle control system and communicated to the CRM unit of the remote control system through the communication devices.
[0183] An operational input chart (1202) shows the settings controlled by the operator on board the vehicle system at different times. This graph (1202) can illustrate, for example, a designated acceleration setting or position (1216) (for example, as determined or dictated by the remote control system and communicated to the vehicle control system), an acceleration setting or position actual (1218) (for example, the acceleration position actually used by the operator on board), a horn indicator (1220) (for example, representing whether and / or when the horn or other vehicle system alarm system is activated ), a bell indicator (1222) (for example, representing whether and / or when another bell or other vehicle system alarm system is activated) and / or an alert indicator (1224) (for example, represents if and / or when the vehicle system's on-board alert system detects that the operator on board is not alert). Alternatively or additionally, other information can be presented. This graph (1202) can be examined to determine whether the operator on board is controlling or attempting to control the vehicle system according to the designated operational settings provided by the remote control system.
[0184] A speed graph (1204) displays designated movement speeds (1226) of the vehicle system (for example, as determined by the remote control system), speed limits (1228) of the route, and actual movement speeds ( 1230) of the vehicle system at different times and / or locations along the route. This chart (1204) can be
Petition 870190039552, of 04/26/2019, p. 249/339
81/136 examined by the remote operator to determine whether and / or when the vehicle system is violating any speed limit and / or whether the vehicle system can move at a faster speed.
[0185] An elevation graph (1206) shows elevations or degrees of the route being traveled by vehicle systems at different locations along the route. An operator fatigue graph (1208) presents information related to the operator's agility on board. The data used to generate the graph (1208) can be obtained by the alert system and / or vehicle control system. If the graph (1208) indicates the agility of the operator on board a vehicle system, then the alert system on board the vehicle system can obtain the data used to generate the graph from the sensor matrix also on board the system vehicle and communicate this information to the CRM unit in the remote control system. If the graph (1208) indicates the agility of the external operator of the remote control system, then the alert system of the remote control system can obtain the data used to generate the graph from the sensor matrix of the remote control system, and communicate this information to the CRM unit on board one or more vehicle systems and / or another remote control system. Operators can monitor the information shown in the graph (1208) to determine whether the operator located remotely (for example, on board a vehicle system or on a remote control system) is alert. Examples of the information that can be presented in the graph (1208) include percentages of responses obtained from the operator when asked to provide an answer through the alert system, a number of times that the operator's eyes change (for example, as determined by examining images or operator video) or other information.
[0186] Data from several different graphs can be examined and compared to determine whether the operator is alert. Per
Petition 870190039552, of 04/26/2019, p. 250/339
For example, graphs can have a common horizontal axis (for example, the same) so that simultaneous events appear in the same locations along the horizontal axes of the graphs. As an example, if an operator in a remote control system is monitoring an operator's agility on board a vehicle system, the external operator can determine whether the fatigue graph indicates that the operator is not alert at the same times or before of the times when the acceleration settings change in the graph (1202), and / or if the regulating valve is being changed after the designated changes in the regulating valve. If the operator on board is slow to change acceleration and / or brake settings, violates speed limits and / or the alert system provides data indicating that the operator is not alert, then the remote control system can generate one or more alarms (for example, on board the vehicle system via the exit device) to wake the operator or to make the operator more alert, can automatically delay or stop the movement of the vehicle system, can send signals to another vehicle system to approach and / or check the operator who appears not to be alert, etc.
[0187] The distribution of at least part of the vehicle systems control system to an offsite location may allow a remotely located operator to help control the movements of several separate vehicle systems. This operator may be able to switch more easily between controlling and / or assisting in the control of various vehicle systems than operators on board, which may allow the external operator to concurrently or simultaneously assist in the control and / or control of multiple vehicle systems. vehicles. The external operator can be replaced by another external operator when a contractual shift or another work shift for the external operator ends, which can allow vehicle systems to continue moving without losing assistance from the external operator. In
Petition 870190039552, of 04/26/2019, p. 251/339
83/136 otherwise, vehicle systems may have to stop for a crew change to allow operators with shifts that are ending to be removed from vehicle systems and replaced by other operators. In addition, the external operator may be more highly trained, have more specialized training and / or be more experienced than operators on board the vehicle system, and this increased experience, superior training and / or specialized training may allow the operator to work on the remote control system so that the experience and / or training of the operator is used to control and / or assist in controlling the movement of several different vehicle systems.
[0188] In one embodiment, multiple operators on the same and / or different remote control systems can assist in the control and / or control operations of the same vehicle system. For example, a first external operator can control the operational settings of a first propulsion generating vehicle in the vehicle system, while a second external operator (in the same or different remote control system) can control the operational settings of a second propulsion generating vehicle. propulsion in the same vehicle system. Alternatively, external operators can control different configurations of the same vehicle, such as an external operator controlling the speed, another external operator monitoring the agility of an operator on board, another external operator monitoring the brake pressures etc., of the same vehicle.
[0189] The number and / or responsibilities of external operators who monitor and / or control a vehicle system may change based on an operational state of the vehicle system, such as when one or more circumstances or scenarios occur. For example, in response to the determination that the vehicle system is entering an area more densely populated (for example, an urban area) than an area
Petition 870190039552, of 04/26/2019, p. 252/339
84/136 above, the number of remote operators controlling and / or assisting in the control of the vehicle system may increase. On the other hand, in response to the determination that the vehicle system is entering an area less densely populated than an earlier area, the number of remote operators controlling and / or assisting in the control of the vehicle system may decrease. As another example, in response to the determination that the cargo carried by the vehicle system is dangerous and / or has a higher priority than other vehicle systems (for example, a shipping arrangement for the cargo has a higher value than other arrangements delivery), the number of remote operators controlling and / or assisting in the control of the vehicle system may increase. As another example, in response to the determination that the vehicle system is traveling in an area that has higher traffic than other vehicle systems, that one or more components of the vehicle system have failed or tend to fail and / or that one or more operators on board are no longer alert, the number of external operators who control and / or help to control the vehicle system can increase.
[0190] The remote control system controller can determine when one or more of these scenarios occur based on data obtained from the vehicle system. For example, the vehicle system may include one or more location determination devices, such as a global positioning system receiver, a radio frequency tag reader, a passive recognition system or the like, which can report locations from the vehicle system to the remote control system. The remote control system can access the vehicle system's travel manifest to determine the load carried by the vehicle system. The sensor array can provide data representative of the operator's agility on board and / or the operational status of the vehicle system components. Based on this and / or other data, the
Petition 870190039552, of 04/26/2019, p. 253/339
85/136 remote control can determine when to increase and / or decrease the number of external operators to assign to the control operations of the same vehicle system. In one aspect, external operators can be located on different remote control systems or terminals, and the controller of a remote control system can connect or disconnect the communication device from additional remote control systems to each other and / or the remote control system. vehicle to change the number of external operators who assist in controlling the same vehicle system.
[0191] Figures 13 to 17 illustrate additional examples of GUIs (1300, 1400, 1500, 1600, 1700) presented to an operator of the remote control system and / or vehicle shown in Figure 1 of the remote control system and / or corresponding vehicle. The GUI shown in Figures 13 to 17 can be presented on the output device, as a screen, to the operator. This GUI shows a horizontal linear map of a route (910) being traversed by various vehicle systems, along with stop locations and other relevant crossing points along the route (910), vehicle system locations and driving directions of vehicle systems.
[0192] A representation of the network status or map (1302) is presented to the operator to indicate the current and future states of the vehicle systems, as estimated or predicted by the remote control system controller based on the current states of the vehicle systems . The status representation is shown next to a horizontal axis (1304) representing different locations along a selected route being traveled by different vehicle systems and next to a vertical axis (1306) representing time. Several lines of movement (908) (for example, lines of movement (908D-F)) represent estimated, programmed or predicted movements of various vehicle systems (for example, vehicle systems (104D-F)), similar to those described above. In the example
Petition 870190039552, of 04/26/2019, p. 254/339
86/136 illustrated, the arrow heads at the ends of the movement lines and / or the slope of the movement lines indicate that the vehicle systems (104D, 104E) are moving along the route from left to right in the perspective of Figures 13 to 17 (for example, a negative slope) and that the vehicle system (104F) is moving along the route in an opposite direction (for example, as indicated by the positive slope). The intersection of lines of motion with different time coordinates (for example, vertical axis) and distance (for example, horizontal axis) indicates where vehicle systems will be located at different times.
[0193] For example, the movement line (908D) can represent the movement of a fourth vehicle system (104D) along the route, the movement line (908E) can represent the movement of a fifth vehicle system (104E) ) along the route, and the movement line (908F) can represent the movement of a sixth vehicle system (104F) along the route (in a direction that is opposite to the direction of movement of the vehicle systems (104D, 104E )). The line of movement (908D) includes a vertical or predominantly vertical portion (1310) (for example, more vertical than horizontal). This part (1310) indicates that the movement of the fourth vehicle system is paused or at least reduced for a period of time during which the part (1310) extends (for example, along the vertical axis). The fourth vehicle system may, for example, deviate from the route to a detour route or other route during this period of time at the location of the part (1310) along the route to allow the vehicle system (104F) to pass the system vehicle (104D) along the route.
[0194] The movement line (908E) also includes a vertical or predominantly vertical part (1308). This part (1308) indicates that the movement of the vehicle system (104E) is paused or at least reduced for a period of time during which the part (1308) moves
Petition 870190039552, of 04/26/2019, p. 255/339
87/136 extends. The vehicle system (104E) can, for example, depart from route (910) to a detour route or other route during this period of time at the location of the part (1308) along the route to allow the vehicle system ( 104F) pass the vehicle system (104E) along the route.
[0195] The passage of the vehicle system (104F) through vehicle systems (104D, 104E) such as vehicle systems (104D, 104E) is stopped or reduced, shown in the GUI by the movement line (908F) of the vehicle system (104F) that intersects or crosses the movement lines (908D, 908E) of vehicle systems (104D, 104E).
[0196] The remote operator can be designated by controlling the movement of vehicle systems traveling along a designated section of the route, such as the part of the route shown in Figures 13 to 17. In response to a vehicle system entering the section of the route being controlled by a remote operator, the vehicle system can begin to be controlled by that remote operator. Before the vehicle system enters this section of the route and after the vehicle system leaves this section of the route, the vehicle system can be controlled by other remote operators. The remote operator in charge of controlling the vehicle systems along the route section can simultaneously or concurrently control the movements of the vehicle systems while these vehicle systems are in the route section.
[0197] Figure 14 illustrates another example of a GUI (1400) shown to an operator of the remote control system and / or vehicle by the corresponding output device. The GUI (1400) represents the current states (for example, relative locations, speeds, etc.) of vehicle systems at a time later than the time represented by the GUI shown in Figure 13. For example, as vehicle systems move around along the route, the CRM unit can update and display the actual locations of the
Petition 870190039552, of 04/26/2019, p. 256/339
88/136 vehicle systems along the route as completed movement lines (for example, movement lines (1008D-F)). The completed motion lines represent parts of the programmed motion lines (908DF) that vehicle systems have completed. The completed movement lines (1008) can be shown differently from the programmed movement lines (908), as shown in Figure 14.
[0198] In the illustrated example, the vehicle system (104F) discovered and / or reported a defective signal along the route at a fault location (1402). This (and / or other failures or factors) can result in the vehicle system (104F) traveling late. The movement of the delayed vehicle system (104F) is represented by a difference (1422) between the programmed movement line (908F) and the completed movement line (1008F) of the vehicle system (104F), as shown in the GUI. The operator of the control system or remote control system can view the GUI to determine the location (1402) of the defective signal (for example, to forward or change the schedules of one or more other vehicle systems based on it) and / or the vehicle system (104F) is moving late.
[0199] Figure 15 illustrates another example of a GUI (1500) shown to an operator of the remote control and / or vehicle by the corresponding output device. The remote control system operator can generate a notification (1502) that informs one or more of the vehicle systems of a change or deviation from the programmed movements of the vehicle systems. In the illustrated example, the remote control system generates a signal that is communicated wirelessly (and / or communicated through one or more wired connections) to the vehicle system (104D) to provide notification (1502) to the vehicle system ( 104D). This notification (1502) can direct the vehicle system (104D) to change speed, such as reducing (in this example), accelerating or otherwise deviating from the
Petition 870190039552, of 04/26/2019, p. 257/339
89/136 programmed movement (908D) for the vehicle system (104D). In response to receiving the notification (1502), the vehicle system controller (104D) can steer the propulsion system to reduce the tractive effort or propelling force generated by the propulsion system and / or it can steer the braking system to increase the braking effort generated by the braking system.
[0200] Figure 16 illustrates another example of a GUI (1600) shown to an operator of the remote control system and / or vehicle by the corresponding output device. The GUI (1600) includes an icon (1602) that represents the location of the defective signal described above. The GUI (1600) also includes an additional programmed motion line (908G) and a completed motion line (1008G) for an additional vehicle system (104G). As shown, completed motion lines (1008D, 1008E) for vehicle systems (104D, 104E) deviate from programmed motion lines (908D, 908E). This can inform the operator that the vehicle systems (104D, 104E) are running late. With regard to the vehicle system (104D), the operator can remotely control the vehicle system (104D) to accelerate to reach the programmed line of motion (908D). For example, while the vehicle system (104D) slowed down relative to the speeds dictated by the programmed line of motion (908D), the vehicle system (104D) may have been accelerated by the operator located remotely so that the vehicle system ( 104D) return to travel according to the movement line (908D), as shown in Figure 16.
[0201] Figure 17 illustrates another example of a GUI (1700) shown to an operator of the remote control system and / or vehicle by the corresponding output device. The GUI (1700) includes graphic climate indicators (1100) that are covered or otherwise shown in the
Petition 870190039552, of 04/26/2019, p. 258/339
90/136 output device, as described above. Climate indicators can represent when and where rainfall (for example, rain, ice and / or snow) is expected to occur, as well as information provided by meteorologists or other sources. The location of weather indicators can visually inform the remote operator when and where weather conditions can affect the movement of vehicle systems. In response to observing the weather indicators, the operator can change the way one or more of the vehicle systems are controlled, such as decreasing the movement of the vehicle systems, increasing the braking distances of the vehicle systems, etc.
[0202] Figures 18A and 18B illustrate another example of a GUI (1800) shown to an operator of the remote control system and / or vehicle shown in Figure 1 by the corresponding output device. The GUI (1800) can be presented to the operator simultaneously or concurrently with the presentation of one or more other GUIs described here (for example, in different parts of the same output device, in different output devices, etc.). The GUI (1800) provides a visual representation of a case manager that allows the operator to select different vehicle systems to control based on other information presented in the GUIs described here. The GUI (1800) presents a map (1802) that indicates the current location of a vehicle system. The map (1802) includes icons indicating programmed and / or unscheduled events (1804) that the vehicle system encountered. For example, the icons shown in Figures 18A and 18B indicate that the vehicle system arrived early in an encounter and pass event (1804A), that an equipment failure event (1804B) was discovered, that the vehicle system performed a unscheduled stop event (1804C), and so on.
[0203] The GUI (1800) can serve as a case manager
Petition 870190039552, of 04/26/2019, p. 259/339
91/136 to allow a remote operator (represented by an operator display part (1806)) to select different vehicle systems to be controlled remotely by the remote operator. Icons indicating the programmed events (1808) of the vehicle system that is selected by the operator are displayed to the remote operator. In the illustrated example, the operator can view these icons to determine what actions the operator must take by remotely controlling the movement of the vehicle system (for example, starting a journey at a scheduled time, reaching a signal on a divergent route, proceeding from a section deviation from the route and end the trip at a scheduled time). The operator can use these icons as a kind of checklist to ensure that the scheduled actions of the vehicle system are completed.
[0204] Figure 19 illustrates a flow chart of an embodiment of a method (1900) for controlling the distributed vehicle system. The method (1900) can be performed by one or more embodiments of the control systems described here. For example, the method (1900) can represent operations performed by one or more of the components of the vehicle control system and / or the remote control system (such as controllers, warning systems, CRM units, etc.) , as described above. In one embodiment, the method (1900) can represent or be used to create a software program to direct the operations of the vehicle control system and / or the remote control system.
[0205] In (1902), information is obtained on one or more vehicle systems that must be controlled remotely. This information may include constitution information, which indicates or represents vehicles in vehicle systems (for example, model number, road number, horsepower capacity,
Petition 870190039552, of 04/26/2019, p. 260/339
92/136 braking, etc.), the load carried by the vehicle systems, the programmed routes to be taken by the vehicle systems, the schedules of the vehicle systems, etc. This information can be received from a variety of sources, such as a dispatcher or scheduling facility, the vehicle systems themselves, or something like that.
[0206] In (1904), a remote operator is communicatively coupled to at least one vehicle system. For example, the remote control system can communicate one or more signals with the vehicle control system of the vehicle system through a communication network that includes and / or is formed from the communication devices. The designation of which remote operator must be communicatively coupled with the vehicle systems can be made based, at least in part, on the information received in (1902). Different external or remote operators may be associated with different geographic areas. For example, vehicle systems that travel through a geographical area associated with a remote operator can be designated, communicatively coupled and controlled remotely by that remote operator during their journey through that geographical area. However, vehicle systems can be assigned to a different remote operator, responsive to leave that geographical area or enter another geographical area associated with the different remote operator. This can allow different operators to become familiar with or have greater skill in controlling the movement of a vehicle system in different areas (in relation to other operators) and designate these operators to control the vehicle systems that travel in the areas associated with the operators.
[0207] In (1906), vehicle system operations and / or operator agility are monitored. Vehicle system operations that are monitored can include acceleration positions,
Petition 870190039552, of 04/26/2019, p. 261/339
93/136 braking, speeds, accelerations, etc. The operator's agility can be monitored by measuring the physiological conditions of an operator on board, such as respiratory rate, heart rate, movements, looks, etc. In one respect, (1906) may include receiving information from one or more operating systems and / or external systems. For example, vehicle system operations can be monitored by receiving information about the vehicles and / or cargo included in the vehicle system.
[0208] In (1908), it is determined whether the operations of the vehicle system should be changed. This determination can be made based on the vehicle system operations and / or the operator's agility that are monitored. For example, if the vehicle system is moving faster or slower than a designated speed, is operating with a different acceleration and / or brake setting than that designated by the remote control system, or if it is deviating from a designated operation, the remote control system can determine to change the operation of the vehicle system to return the vehicle system to move according to the designated operation. As another example, if the operator on board is no longer alert, then the remote control system may decide to activate an alarm to contact the operator on board, change the movement of the vehicle system or modify the operation of the vehicle system. . If the operation of the vehicle system is changed, the flow of the method (1900) can proceed towards (1910). Otherwise, the flow of the method (1900) can proceed towards (1912).
[0209] In (1910), the change in operation in the vehicle system is communicated from the remote control system to the vehicle control system. This change in operation can be communicated as a designated reference point or other instruction that is communicated via the communication devices to the vehicle control system. In (1912), it is
Petition 870190039552, of 04/26/2019, p. 262/339
94/136 a determination is made as to whether the relationship or designation of the vehicle system operator should be changed. The operator list represents the number of external operators who control the operations of the vehicle system. For example, an operator ratio can be calculated as the number of external or remote operators for the number of operators on board controlling the movement of the vehicle system, the number of external or remote operators for the total number of external and onboard operators controlling the movement of the vehicle system, or other number. The operator's relationship may change in response to a change in operating circumstances or scenarios. For example, in response to the determination that the vehicle system is entering an area more densely populated than an earlier area, the number of remote operators controlling and / or assisting in controlling the vehicle system may increase.
[0210] In response to the determination that the cargo carried by the vehicle system is dangerous and / or has a higher priority than other vehicle systems, the number of remote operators controlling and / or assisting in the control of the vehicle system may increase. As another example, response to the determination that the vehicle system is traveling in an area that has higher traffic than other vehicle systems, that one or more components of the vehicle system have failed or tend to fail and / or that one or more operators on board are no longer alert, the number of external operators who control and / or help to control the vehicle system can increase. This can be done automatically by the remote and / or vehicle control system or manually by a supervisor or consensus of the remote operators.
[0211] In addition, or as an alternative to changing the operator's relationship, the operator's designation can be modified. The designation of the
Petition 870190039552, of 04/26/2019, p. 263/339
95/136 operator is the indication of which vehicle system is at least partially monitored and / or controlled by a remote operator. A remote operator can be assigned to several vehicle systems, as described above. The assignment of a remote operator to a vehicle system can be determined by the remote control system, for example, determining which vehicle systems are traveling (and / or are scheduled to travel within or through) a geographical area (for example, geographic fence) associated with a remote operator (and then assign those vehicle systems to the remote operator). As another example, the assignment of a remote operator can be determined based on what skills are needed to remotely control a vehicle system. Some vehicle systems can carry dangerous cargo, can travel on difficult terrain (for example, a series of curves, urban areas, etc.), can be more difficult to control compared to other vehicle systems (for example, due to the number of propulsion generating vehicles, the weight of the load and / or vehicles, the age of the vehicles, etc.), may have systems or controls that require specialized training, or may require a skill set that not all operators have.
[0212] As another example, the designation of a remote operator can be determined based on an operator's work history. An operator who has remotely monitored and / or controlled a particular vehicle system or a particular type of vehicle (for example, based on the model number, age, etc., of the vehicles generating propulsion in the vehicle system) more than another operator, can be assigned to remotely control that same vehicle system or type of vehicle system instead of the other operator. As another example, the assignment of a remote operator can be determined based on a work shift
Petition 870190039552, of 04/26/2019, p. 264/339
Operator 96/136. For example, if a remote operator is approaching the end of a contractually agreed or designated work shift, another remote operator who has more time available during his or her work shift may be assigned to a vehicle system to avoid exceeding the work shift. .
[0213] If the operator's relationship or designation is to change, then the flow of the method (1900) can proceed to (1914). Otherwise, the method flow (1900) can return to (1906). The method (1900) can proceed in a circuit way until it is finished, until the trip of the vehicle system is completed, and / or until a vehicle system being remotely controlled leaves the section of the route being controlled by the control system remote.
[0214] In (1914), an allocation or designation of remote operators controlling the same vehicle system is changed. For example, if the determination in (1912) reveals that more remote operators are needed to remotely control the movement of a vehicle system, then one or more additional remote operators begin to remotely control the movement of the vehicle system. Conversely, if the determination in (1912) reveals that fewer remote operators are needed to remotely control the movement of a vehicle system, then one or more remote operators currently controlling the movement of the vehicle system are assigned to other tasks that do not include the remote control of vehicle system movement.
[0215] In one embodiment, a distributed control system includes a remote control system configured to be communicatively coupled with multiple separate vehicle systems. The remote control system is configured to remotely control the operation of vehicle systems and / or communicate with the local

The remote control system is also configured for one or more changes to how many of the vehicle systems are controlled simultaneously by the remote control system or changes to how many remote operators of the remote control system simultaneously control the same vehicle system as the vehicle systems.

[0246] One or more embodiments of the inventive object material described herein refer to systems and methods that allow the control of the movement of a vehicle system for transfer between one or more of a vehicle control system on board and a remote control system for one of the vehicle control system on board or the remote control system for controlling the movement of the vehicle system. The systems and methods communicatively connect the remote control system and the vehicle control system on board and transfer control of the vehicle system's movement based on one or more of a location, a vehicle system condition or a operator request and / or condition. The location can be a geographical area or designated segment of a route that is known a priori or calculated according to some characteristics of the trail and / or region. For example, these areas can be based on population density, road equipment locations, level crossing locations, vehicle workplaces (for example, picking up or adjusting vehicles), a designated practice area for manual control of the vehicle or something like that. The condition can be a fault state

103/136 of the vehicle system, a loss of communication between the vehicle system and the remote control system, an increase in a fuel consumption rate or the like. The systems and methods block operator control on board the vehicle system, receive an instruction from the remote control system to test a vehicle system operation and communicate visual data representative of an area outside the vehicle system when controlling movement from the vehicle system transfers to the remote control system. The systems and methods automatically stop the vehicle system, if necessary, activate the vehicle control system on board and disconnect communication with the remote control system when the movement control of the vehicle system transfers to the vehicle control system on board.
[0247] This object material can be used in connection with railway vehicles and railway vehicle systems, or, alternatively, it can be used with other types of vehicles. For example, the object material described here can be used in connection with automobiles, trucks, mining vehicles, other agricultural vehicles (for example, vehicles that are not designed or are not legally permitted for travel on public roads), aerial vehicles ( for example, fixed wing aircraft, drones or other unmanned aircraft, etc.) or marine vessels.
[0248] The vehicle consists of or the vehicle system may include two or more vehicles mechanically coupled together to travel a route together. Optionally, the vehicle system can include two or more vehicles that are not mechanically coupled to each other, but that travel together along a route. For example, two or more cars can communicate wirelessly with each other, as vehicles travel together along the route, as a vehicle system to coordinate movements with each other. Optionally, a vehicle system can consist of or be formed from
Petition 870190039552, of 04/26/2019, p. 272/339
104/136 from a single vehicle.
[0249] Figure 20 illustrates an embodiment of a vehicle control system (2000) used to control the movement of a vehicle system (2004). The vehicle system (2004) can represent one or more of the other vehicle systems shown and / or described here. The illustrated vehicle system (2004) includes a propulsion generating vehicle (2004) and non-propulsion generating vehicles (2006) that travel together along a route (2008). Although vehicles (2004, 2006) are shown to be mechanically coupled to each other, optionally vehicles may not be mechanically coupled to each other.
[0250] The propulsion generating vehicle (2004) is shown as a locomotive, non-propulsion generating vehicles (2006) are shown as railway wagons, and the vehicle system (2004) is shown as a train in the embodiment illustrated. Alternatively, vehicles (2004, 2006) can represent other vehicles, such as automobiles, marine vessels or the like, and the vehicle system (2004) can represent a grouping or coupling of these vehicles. The number and arrangement of vehicles (2004, 2006) in the vehicle system (2004) are provided as an example and are not intended to be limitations in all forms of realization of the subject matter described here.
[0251] The vehicle system includes an on-board vehicle control system (OVCS) (2014). OVCS may include hardware circuits or circuits that include and / or are connected to one or more processors (for example, one or more microprocessors, field programmable port arrays, and / or integrated circuits). The OVCS can control or limit the movement of the propulsion generating vehicle (2004) and / or the vehicle system (2004) which includes vehicles (2004, 2006) based on one or more limitations. For example, OVCS can prevent vehicles and / or the vehicle system
Petition 870190039552, of 04/26/2019, p. 273/339
105/136 entering a restricted area, can prevent the vehicle and / or vehicle system from leaving a designated area, can prevent the vehicle and / or vehicle system from traveling at a speed that exceeds an upper speed limit, can prevent the vehicle and / or vehicle system from traveling at a speed that is less than a lower speed limit, may prevent the vehicle and / or vehicle system from traveling in accordance with a designated travel plan generated by a management system of energy, or something like that. The OVCS will be discussed in more detail with Figure 19.
[0252] The propulsion generating vehicle (2004) includes a control mediation system (2016) arranged on board the vehicle (2004). The control mediation system represents a hardware circuit that includes and / or is connected to one or more processors (for example, microprocessors, controllers, field programmable port arrays, integrated circuits or the like). The control mediation system is operationally connected with the vehicle's OVCS (2004) through a communication link (2024). The communication link (2024) can represent a wired or wireless connection. Optionally, the control mediation system can be arranged outside the vehicle system (2004) and can communicate wirelessly with the OVCS. In addition or alternatively, the vehicle system (2004) may include one or more additional propulsion generation vehicles in which the one or more additional propulsion generation vehicles may include a control mediation system. For example, the vehicle system may include two or more propulsion generation vehicles (2004), where one or more, or each, of the vehicles includes a control mediation system. Optionally, the vehicle system (2004) can include two or more propulsion generation vehicles (2004), where only one vehicle (2004) includes a control mediation system.
Petition 870190039552, of 04/26/2019, p. 274/339
106/136 [0253] The control mediation system is operationally connected with a remote control system that is arranged outside the vehicle system (2004). The remote control system can represent one or more of the remote control systems described here, and can remotely control the movement of the vehicle system (2004) by communicating operational motion settings to the control mediation system (2116) on board the vehicle ( 2004). Multiple operators in the remote control system can remotely control the movement of the vehicle system (2004). For example, multiple operators can remotely control multiple different moving heavy vehicles (for example, trains, boats, automobiles or the like).
[0254] The remote control system is separated from the vehicle system (2004) by a distance (2026). The distance can be 50 meters, 500 meters, 500 kilometers, 5000 kilometers or something like that. The distance between the vehicle system (2004) and the remote control system may be beyond the line of an operator's location from the remote control system to the vehicle system (2004), may extend between different time zones, may extend between positions different geographic (e.g. different city, county, state, country) or similar. For example, an operator of the remote control system can control the movement of the vehicle system (2004) when the operator of the remote control system is located in New York and the vehicle system (2004) is located in Utah. Alternatively, the distance may be within a line from a remote control system operator's location to the vehicle system (2004). For example, the distance can be less than 50 meters.
[0255] The remote control system is communicatively linked to the vehicle's OVCS (2004) through communication links established between the remote control system and the vehicle system
Petition 870190039552, of 04/26/2019, p. 275/339
107/136 (2004). For example, the remote control system communicates control signals to a first communication device (2010) (for example, a first satellite (2010a)) over the communication link (2018). The first satellite (2010a) communicates the control signals to a second communication device (2010) (for example, a second satellite (2010b)) over the communication link (2020). The second satellite (2010b) communicates the control signals to the control mediation system (2016) on board the vehicle system (2004) via the communication link (2022). Optionally, less than two or more than two satellites can be used to communicate signals between the remote control system and the vehicle system (2004). Additionally or alternatively, the vehicle system (2004) can communicate with the remote control system with relays for terrestrial communications (for example, radio towers). Optionally, the vehicle system (2004) and the remote control system can communicate via communication links established between one or more satellites and / or one or more radio towers, or the like. Additionally, the remote control system is communicatively linked to the OVCS through the communication link (2024) established between the control mediation system and the OVCS. For example, the control mediation system communicates control signals between the remote control system (for example, over communication links (2018, 2020, 2022)) and OVCS (for example, over communication link (2024) ).
[0256] The remote control system communicates control signals to the vehicle system (2004) via communication links to remotely control the movement of the vehicle system (2004) as the vehicle system (2004) travels along the route (2008). The control signals dictate the operational movement settings of the vehicle system (2004) that include one or more of a degree of
Petition 870190039552, of 04/26/2019, p. 276/339
108/136 acceleration, a brake setting, speed setting or something like that. The remote control system will be described in more detail below with Figure 22.
[0257] The one or more processors in the control mediation system connect the remote control system disposed outside the vehicle system communicatively with the OVCS disposed on board the vehicle system (2004). The one or more processors in the control mediation system mediate a process of transferring motion control from the vehicle system (2004) from the remote control system to the OVCS or from the OVCS to the remote control system. For example, the control mediation system mediates (for example, manages, arbitrates or the like) which system controls the vehicle system (2004) to ensure that the movement of the vehicle system (2004) is controlled by a single system in a given moment. For example, when the movement control of the vehicle system is managed by the remote control system, the movement of the vehicle system (2004) cannot be controlled autonomously by the OVCS or manually by an operator on board the vehicle system (2004) . In addition, when the movement control of the vehicle system (2004) is administered by the OVCS (manually or autonomously), the movement of the vehicle system (2004) cannot be controlled by the remote control system.
[0258] Control of movement of the vehicle system (2004) can be transferred from the remote control system to the OVCS or from the OVCS to the remote control system based on a location and / or region, if the vehicle system ( 2004) suffer a certain condition, based on the request and / or condition of the vehicle system operators (2004), or something like that. The location is a designated geographical area or a designated segment of the route (2008). The location can be a route length (for example,
Petition 870190039552, of 04/26/2019, p. 277/339
109/136 example, 10 kilometers, 50 kilometers or something like that), it can be a geographic area (for example, a city, a municipality, a state or similar), it can be a predetermined or non-predetermined length and / or geographical area (for example, determined before or during the transit of the vehicle system (2004)) that is known a priori or calculated according to some characteristics of rail and / or region, or something similar. For example, these areas can be based on population density, road equipment locations, level crossing locations, vehicle workplaces (for example, picking up or adjusting vehicles), a designated practice area for manual control of the vehicle (2004), or something like that.
[0259] In addition, vehicle system movement control (2004) can transfer from the remote control system to the OVCS or from the OVCS to the remote control system based on a vehicle system condition ( 2004). For example, the condition may be a failure state of the vehicle system (2004), it may be a loss of communication between the vehicle system (2004) and the remote control system, it may be at the request of the local or remote operator, it may be a lack of agility or other physical condition of the local and / or remote operator, or something like that. Methods that determine whether control of the vehicle system (2004) is to transfer from one system to another, and which transfer control of the vehicle system will be discussed in more detail below, referring to Figures 23 and 24.
[0260] Figure 21 is a schematic illustration of the vehicle on board control system (OVCS) (2014) arranged on board the vehicle (2004) according to an embodiment. The OVCS controls the movement of the vehicle system (2004). The OVCS can be one or more controlled manually (for example, by an operator on board the vehicle (2004)) and / or autonomously with an energy management system (EMS) (2102).

OVCS can include or represent one or more hardware circuits or circuits that include, are connected to or that include and are connected to one or more processors, controllers or other devices based on hardware logic. For example, an operator on board the vehicle (2004) can manually control the movement of the vehicle system (2004) by manually controlling the OVCS hardware, drivers, devices or the like. Additionally or alternatively, the EMS can autonomously control the movement of the vehicle system (2004) (for example, without entry by an operator on board the vehicle system (2004)) by electrically communicating directions and / or commands to the systems and devices associated with the OVCS (2114).
[0261] The EMS may include hardware circuits or circuits that include and / or are connected to one or more processors. The EMS can create a travel plan for vehicle travel (2004, 2006) and / or the vehicle system (2004) that includes vehicles (2004, 2006). A trip plan may designate operational configurations of the propulsion generating vehicle and / or the vehicle system as a function of one or more of time, location or distance along a route for a trip. Traveling according to the operational configurations designated by the travel plan can reduce fuel consumption and / or emissions generated by vehicles and / or vehicle systems (2004) in relation to vehicles and / or vehicle systems traveling according to other operational configurations that are not designated by the travel plan. Vehicle identities in the vehicle system (2004) can be known by the EMS so that the EMS can autonomously control the operations of the vehicle system (2004). In addition, the EMS can determine which operational settings to designate for a travel plan to achieve a goal of reducing fuel consumption and / or emissions generated by the fuel system.

111/136 vehicle during the journey.
[0262] The OVCS is connected with an input device (2104) and an output device (2106). The OVCS can receive manual input from an operator of the propulsion generating vehicle (2004) through the input device, such as a touch screen, keyboard, electronic mouse, microphone or the like. For example, the OVCS can manually receive input changes for tractive effort, braking effort, speed, power output and the like, from the input device. The OVCS (2514) can receive a single instance of a drive from the input device to initiate the establishment of a communication link between the OVCS and the control mediation system.
[0263] The OVCS can present information to the vehicle operator using the output device, which can represent a display screen (for example, touch screen or other screen), speakers, printer or the like. For example, OVCS can display the identities and situations of other vehicles in the vehicle system, lost vehicle identities (for example, those vehicles from which the vehicle has not received the situation), content of one or more command messages or something like that . The output device provides a notification signal to the vehicle operator that automatically informs (for example, notifies) the vehicle operator that the movement control of the vehicle system has changed. For example, the output device can change color, change a display format, ring a bell, communicate a voice command, communicate a sound or the like that vehicle system motion control is and / or has transferred one or more to. the remote control system or the OVCS. Optionally, the output device can present instructions to the operator on board the vehicle system from the OVCS which instructs the operator to manually control the movement of the vehicle system.

112/136
For example, the output device can instruct an acceleration setting, speed setting, brake setting, or the like, for the vehicle system operator to the operator on board the vehicle system to manually control the movement of the vehicle. vehicle system.
[0264] The OVCS is connected to a propulsion subsystem (2108) of the propulsion generating vehicle. The propulsion subsystem can represent one or more of the propulsion systems described and / or shown here. The propulsion subsystem provides traction and / or braking effort for the propulsion generating vehicle. The propulsion subsystem may include or represent one or more engines, mechanisms, alternators, generators, brakes, batteries, turbines and the like that operate to propel the propulsion generating vehicle and / or the vehicle system under the manual or autonomous control that is implemented by OVCS. For example, the OVCS can direct propulsion subsystem operations by the OVCS by generating control signals autonomously or based on an operator's manual input.
[0265] The OVCS is connected with a memory (2112) and a communication device (2110). The memory can represent an on-board device that stores data in an electrical and / or magnetic way. For example, memory can represent a computer hard drive, random access memory, read-only memory, dynamic random access memory, an optical drive, or the like. The communication device includes or represents hardware and / or software that is used to communicate with other vehicles in the vehicle system. For example, the communication device may include a transceiver and associated circuits (for example, antenna (2030) in Figure 20) for wireless communication (for example, communication and / or reception) of call messages, command messages, messages reply, relay messages or something
Petition 870190039552, of 04/26/2019, p. 281/339
113/136 look like. Optionally, the communication device includes circuits for communicating messages over a wired connection, such as a vehicle system electrical multiple unit (eMU) line (not shown), catenary or third rail of electrically powered vehicles, or another route driver between or among vehicles in the vehicle system (2004) and / or between or among vehicles in a different vehicle system.
[0266] The OVCS can control the communication device by activating the communication device. The OVCS can examine the messages that are received by the communication device from one or more of the control mediation systems or other vehicles in the vehicle system.
[0267] The OVCS is connected with an object detection sensor (2120). The object detection sensor can include hardware circuits or circuits and / or software that include and / or are connected to one or more processors. The detection sensor can obtain sensor data that is indicative of an area outside the vehicle system. For example, the detection sensor can get sensor data in an area in front of the vehicle system in a direction of travel of the vehicle system, in an area behind the vehicle system in a direction of travel of the vehicle system or something like. The detection sensor may include a camera that obtains motionless and / or moving visual data from an area of the route in the direction of travel of the vehicle system and / or in a direction opposite to the direction of travel of the vehicle system. For example, the detection sensor can be one or more cameras that capture still images at the front (for example, in the direction of travel) and at the rear (for example, opposite to the direction of travel) of the vehicle system. Optionally, the detection sensor can be a radar system that sends and receives reflected pulses from an object to detect the presence of an object in an area outside the vehicle system. Optionally, the detection sensor can be a detection system
Petition 870190039552, of 04/26/2019, p. 282/339
114/136 alternative that obtains data from an area outside the vehicle system. The detection sensor can obtain data (for example, visual, statistical, radar or the like) at a distance of 2 meters, 25 meters, 100 meters, 500 meters, 1000 meters or so, outside and in a direction away from the vehicle system.
[0268] The object detection sensor can include one or more sensor devices positioned around the vehicle in one or more of the vehicle's interior and / or exterior (not shown). For example, a detection device can be positioned at a front and / or rear end of the vehicle to obtain data for the vehicle and / or vehicle system that is moving in a first and opposite direction (for example, to back and forth). Optionally, one or more detection devices can be used, and the placement of the one or more detection devices can vary.
[0269] Figure 22 is a schematic illustration of the remote control system (2012) in Figure 20. The remote control system remotely controls the movement of the vehicle system (2004). For example, the remote control system remotely controls the movement of the vehicle system by communicating with the control mediation system over communication links. The remote control system represents a hardware circuit that includes and / or is connected to one or more processors (for example, microprocessors, controllers, field programmable port arrays, integrated circuits or the like).
[0270] The remote control system generates control signals that are communicated by a communication unit (2202). The control signals remotely control the movement of the vehicle system (2004). The communication unit (2202) can send or receive one or more communication signals with the vehicle system through the communication links between the
Petition 870190039552, of 04/26/2019, p. 283/339
115/136 control mediation system and the remote control system. The remote control system receives one or more image data and / or sensor data detected by the object detection sensor on board the propulsion generating vehicle. For example, the remote control system can receive visual data obtained by the detection sensor and communicated by the control mediation system that is representative of an area outside the vehicle system. Optionally, the remote control system can receive status notifications such as vehicle system equipment status, current vehicle and / or vehicle system settings, location of the vehicle system or the like, from vehicles and / or the system vehicle.
[0271] The remote control system may include one or more input devices (2206) and / or output devices (2208), such as a keyboard, electronic mouse, digital pen, microphone, touchpad or the like. Additionally or alternatively, the input and / or output devices can be used to communicate with one or more of a vehicle system operator or the OVCS. The remote control system may include one or more displays (2204), such as a touch screen, display screen, electronic viewfinder or the like. The displays can visually, graphically, statistically or the like, display information to the remote control system operator. The remote control system is operationally connected with vehicle system components. Additionally or alternatively, the remote control system can be operatively linked to alternative components or systems on board and / or outside the vehicle system.
[0272] The remote control system can include a power unit (2210). The power unit powers the remote control unit. For example, the power unit can be a battery and / or circuit that
Petition 870190039552, of 04/26/2019, p. 284/339
116/136 supplies electrical current to power other components of the remote control system. Additionally or alternatively, the power unit can supply electrical energy to one or more other systems.
[0273] Returning to Figure 20, the remote control system is configured to remotely control the movement of the vehicle system by sending control signals to the OVCS on board the vehicle through the control mediation system. In addition, the OVCS is configured to control the movement of the vehicle system, one or more in an autonomous or manual manner, by an operator on board the vehicle system. The one or more processors in the control mediation system control which of the remote control systems or the OVCS control the movement of the vehicle system at any given time. In addition, the control mediation system mediates the transfer of control of movement from the vehicle system from the remote control system to the OVCS or from the OVCS to the remote control system.
[0274] Figure 23 illustrates a flow chart of a method (2300) for transferring motion control from the vehicle system from the remote control system to the OVCS. Method steps (2300) can be completed one or more before or during the transfer of motion control from the vehicle system from the remote control system to the OVCS.
[0275] In (2302), the remote control system is communicatively linked to the OVCS through the control mediation system. For example, the remote control system is communicatively connected to the control mediation system by the communication link and the OVCS is communicatively connected to the control mediation system by the communication link.
[0276] In (2304), the movement control of the vehicle system
Petition 870190039552, of 04/26/2019, p. 285/339
117/136 is controlled by the remote control system. For example, when the movement control of the vehicle system is controlled by the remote control system, an autonomous operator or controller (for example, the EMS) on board the vehicle system is unable to control the movement of the vehicle system. The remote control system remotely controls the movement of the vehicle system, communicating control signals to the OVCS. The control signals dictate the operational settings of the vehicle system movement, which include one or more acceleration degree settings, brake settings, speed settings, or the like. For example, one or more operators of the remote control system can send a control signal to the OVCS through the control mediation system, instructing the OVCS to increase the speed of the vehicle system to 75 kilometers per hour. In response to receiving the control signal, the OVCS directs the propulsion subsystem to increase the degree of acceleration setting to adhere to the 75 km / h speed direction.
[0277] In (2306), a decision is made to determine whether control of the vehicle system's movement needs to be transferred from the remote control system to the OVCS. The decision is based on one or more of a location, a vehicle system condition or an operator request and / or condition (for example, on board or outside). For example, motion control of the vehicle system may need to be transferred to the OVCS if the vehicle system is traveling through a congested region (for example, a city, a municipality). Optionally, the location of the vehicle system can be any alternative location that can be benefited by OVCS by controlling the movement of the vehicle system.
[0278] Alternatively, control of the movement of the vehicle system can be transferred to the OVCS if the vehicle system has gone through a fault state. For example, one or more of the
Petition 870190039552, of 04/26/2019, p. 286/339
118/136 vehicle control on board the propulsion generating vehicles may have identified a failure in the aerodynamic brake of the propulsion subsystem. Optionally, the vehicle system may have suffered a loss of communication with the remote control system. For example, one or more of the communication links may have been compromised. Optionally, the vehicle system condition can be any alternative condition that would benefit the OVCS by controlling the movement of the vehicle system.
[0279] Alternatively, control of the movement of the vehicle system can be transferred to the OVCS if the operator of the remote control system or the operator of the OVCS has initiated a request to transfer control of the movement of the vehicle system to the OVCS. For example, the external operator of the remote control system can reach a final working time and needs to transfer control of movement from the vehicle system to the OVCS for manual and / or autonomous control. Optionally, the external operator of the remote control system may experience a decrease in agility by forbidding the external operator to safely control the movement of the vehicle system. Optionally, the request and / or condition of the operator on board the vehicle system and / or the operator of the remote control system can be any alternative request or condition that would benefit from the OVCS controlling the movement of the vehicle system.
[0280] If the control of the vehicle system movement does not need to be transferred to the OVCS, then the method flow returns to (2304) and the remote control system continues to remotely control the vehicle system movement. If the control of the movement of the vehicle system needs to be transferred to the OVCS, then the method flow proceeds to (2308).
[0281] In (2308), the transfer of control of the movement of the vehicle system from the remote control system to the OVCS is initiated. THE
Petition 870190039552, of 04/26/2019, p. 287/339
119/136 transfer of control can be initiated by one or more operators of the remote control system, an operator on board the vehicle system or autonomously by the OVCS. In (2309), a determination is made whether the OVCS energy management system (EMS) is ready to autonomously control the movement of the vehicle system. For example, the EMS can automatically control the movement of the vehicle system without operator intervention. The EMS may not be ready to autonomously control the movement of the vehicle system if the vehicle system is in a particular location / region, if the vehicle system has experienced a certain condition or based on the request and / or condition of local operators or remote. For example, the EMS may not be ready to autonomously control the movement of the vehicle system if the vehicle system is traveling through a congested area. Optionally, if the EMS is not ready to control the movement of the vehicle system, the EMS can automatically present instructions to the operator on board the vehicle system instructing the operator to control the movement of the vehicle system. If the EMS is ready to control the movement of the vehicle system, the flow of the method will continue. If the EMS is not ready to autonomously control the vehicle system, the flow of the method will proceed towards (2310).
[0282] In (2310), a determination is made if an operator is on board the vehicle system. If an operator is not on board the vehicle system, then the method flow proceeds to (2311), where the vehicle system stops to allow an operator to board the vehicle system and the method flow proceeds to (2312). If an operator is on board the vehicle system, the flow of the method proceeds towards (2312).
[0283] In (2312), the OVCS is activated to allow one or more
Petition 870190039552, of 04/26/2019, p. 288/339
120/136 manual or autonomous control of the movement of the vehicle system. For example, the OVCS may be in a configuration for control by the remote control system only before transferring control of movement from the vehicle system. The OVCS can be activated for a second different configuration to allow control of the vehicle system by the OVCS (for example, autonomous and / or manual control). The OVCS can be activated to allow the operator on board the vehicle system to manually control the movement of the vehicle system. Optionally, the OVCS can be activated to allow the EMS to automatically control the movement of the vehicle system without operator intervention.
[0284] In (2314), the one or more processors of the control mediation system complete the transfer of control of the movement of the vehicle system from the remote control system. For example, the control mediation system can block or prevent the control signals communicated by the remote control vehicle from being received by the OVCS.
[0285] In (2316), one or more of the operator on board the vehicle system, the one or more operators of the remote control system or an operator of an alternative system are notified that the transfer of control of the movement of the system vehicle is complete. For example, the operator on board the vehicle system (2004) can be notified by the output device by changing to a different color, changing to a different display format, ringing a bell, communicating a vocal command, communicating a sound, through the OVCS changing and / or dimming the vehicle's interior lights, or something like that. Optionally, the operator on board the vehicle system can be notified by any alternative method. The one or more remote control system operators can be notified that the transfer of control of the vehicle system movement is complete by one or more of the monitor or the output device changing
Petition 870190039552, of 04/26/2019, p. 289/339
121/136 for a different color, changing to a different display format, ringing a bell, communicating a vocal command, communicating a sound or the like. Optionally, the one or more remote control system operators can be notified by any alternative method.
[0286] In (2318), the OVCS disconnects communication with the remote control system. For example, the control mediation system breaks the communication links between the remote control system and the vehicle system. Optionally, communication links can remain intact and the one or more processors in the control mediation system can prohibit the control signals communicated by the remote control system from being delivered to the OVCS.
[0287] Figure 24 illustrates a flow chart of a method (2400) for transferring motion control from the vehicle system from the OVCS to the remote control system. The method operations (2400) can be completed one or more before or during the transfer of motion control from the vehicle system from the OVCS to the remote control system.
[0288] In (2402), the OVCS is communicatively linked to the remote control system through the control mediation system. For example, the OVCS is communicatively connected to the control mediation system by the communication link, and the remote control system is communicatively connected to the control mediation system by the communication links.
[0289] In (2404), the movement control of the vehicle system is controlled by the OVCS. For example, when the movement control of the vehicle system is controlled by the OVCS, one or more operators of the remote control system are unable to control the movement of the vehicle system. The OVCS controls the movement of the vehicle system by directing
Petition 870190039552, of 04/26/2019, p. 290/339
122/136 the propulsion subsystem to alter the movement of the vehicle system by one or more changes in the acceleration degree setting, brake configuration, speed configuration or the like. For example, the OVCS can autonomously or manually, by an operator on board the vehicle's direct propulsion subsystem, decrease the speed of the vehicle system to 45 kilometers per hour. In response, the propulsion subsystem can decrease the acceleration setting and / or apply the brakes to adhere to the 45 km / h speed direction.
[0290] In (2406), a decision is made to determine whether control of the vehicle system's movement needs to be transferred from the OVCS to the remote control system. The decision is based on one or more of a location, a vehicle system condition or an operator request and / or condition (for example, on board or outside). For example, control of the movement of the vehicle system may need to be transferred to the remote control system if the vehicle system travels in an unobstructed area (for example, an open plane with minimal or no natural or artificial obstacles) ). Optionally, the vehicle system location can be any alternative location that would benefit from the remote control system that remotely controls the movement of the vehicle system.
[0291] Alternatively, control of the movement of the vehicle system can be transferred to the remote control system if the vehicle system has not experienced a fault state for a designated period of time and / or travel length along the route. For example, the OVCS can communicate to one or more of the remote control system or an alternative system that the state of each vehicle and / or the vehicle system is functioning properly over a certain period of time and / or distance traveled. Optionally, the condition of the
Petition 870190039552, of 04/26/2019, p. 291/339
123/136 vehicle can be any alternative condition that would benefit from the remote control system that remotely controls the movement of the vehicle system.
[0292] Alternatively, the control of the movement of the vehicle system can be transferred to the remote control system if the operator of the OVCS or the operator of the remote control system has initiated a request to transfer control of the movement. For example, the operator on board the OVCS may achieve a designated break time and need to transfer control of movement from the vehicle system to the remote control system to perform a designated work break. Optionally, the operator on board the OVCS may experience a decrease in agility by prohibiting the operator on board the OVCS from safely controlling the movement of the vehicle system. Optionally, the request and / or condition of the operator on board the vehicle system and / or the operator of the remote control system can be any alternative request or condition that would benefit from the remote control system that controls the movement of the vehicle system.
[0293] If the motion control of the vehicle system does not need to be transferred to the remote control system, then the method flow returns to (2404) and the OVCS continues to control the movement of the vehicle system (autonomously or manual). If control of the movement of the vehicle system needs to be transferred to the remote control system, the method flow proceeds to (2407).
[0294] In (2407), the transfer of control of movement from the vehicle system of the OVCS to the remote control system is initiated. The transfer of control can be initiated by one or more operators of the remote control system, an operator on board the vehicle system or autonomously by the OVCS.
Petition 870190039552, of 04/26/2019, p. 292/339
124/136 [0295] In (2408), the control mediation system blocks an operator and autonomous control of the EMS on board the vehicle system. For example, the control mediation system can prevent control signals, one or more of the operator's inputs on board the vehicle control system or autonomously by the OVCS from controlling the movement of the vehicle system.
[0296] In (2410), the OVCS receives an instruction from the remote control system through the control mediation system to test a vehicle system operation. For example, the instruction may be to perform an aerodynamic test, to turn the headlights on and / or off or something like that.
[0297] In (2412), the OVCS communicates visual data representative of an area outside the vehicle system to the remote control system. For example, the object detection sensor can obtain still or moving image data from the outside area of the vehicle system (for example, in front, behind, side, above or similar). The OVCS can communicate the obtained visual data to the remote control system, in which the visual data is displayed on the remote control system display. Visual data informs the remote control system operator of one or more of the conditions, location, region or the like of the vehicle system. For example, visual data can inform the operator of the remote control system that the route is free of any obstructions. In addition, the visual data informs the operator of the remote control system whether the (2410) instruction was received by the OVCS and whether the instruction was successfully completed by the OVCS. For example, visual data can inform the operator of the remote control system that the instruction to turn the headlights on and / or off has been received and / or completed accurately.
[0298] In (2414), the one or more processors of the control mediation system complete the transfer of control of the movement of the
Petition 870190039552, of 04/26/2019, p. 293/339
125/136 OVCS vehicle system for the remote control system. For example, the control mediation system can block or prevent the OVCS control signals (manually or autonomously) from controlling the movement of the vehicle system.
[0299] In (2416), one or more of the operator on board or close to the vehicle system, one or more operators of the remote control system or an operator of an alternative system are notified that the transfer of control of the movement of the system vehicle is complete. For example, the operator on board the vehicle system can be notified by the output device by changing to a different color, changing to a different display format, ringing a bell, communicating a vocal command, communicating a sound, by OVCS changing and / or darkening the vehicle’s interior lights, or something like that. Optionally, the operator on board the vehicle system can be notified by any alternative method. The one or more remote control system operators can be notified that the transfer of control of the vehicle system movement is complete by one or more of the display or the output device changing to a different color, changing to a different display, ringing a bell, communicating a vocal command, communicating a sound or the like. Optionally, the one or more remote control system operators can be notified by any alternative method.
[0300] Figure 25 illustrates an embodiment of a system (2500) that includes a vehicle system (2502). The illustrated vehicle system (2502) includes a propulsion generating vehicle (2504) and non-propulsion generating vehicles. Although the vehicles are shown to be mechanically coupled to each other, optionally the vehicles may not be mechanically coupled to each other.
[0301] The propulsion generating vehicle (2504) includes a
Petition 870190039552, of 04/26/2019, p. 294/339
126/136 vehicle control on board (OVCS) (2514) (corresponding to OVCS (2014)) arranged on board the vehicle (2504). The OVCS (2514) can include hardware circuits or circuits that include and / or are connected with one or more processors. The OVCS (2514) can control or limit the movement of the propulsion generating vehicle (2504) and / or the vehicle system (2502) which includes vehicles based on one or more limitations.
[0302] The system (2500) includes a remote control system (2512) (corresponding to the remote control system (2012) of Figure 20) disposed outside the vehicle system (2502). The remote control system (2512) remotely controls the movement of the vehicle system (2502) by communicating operational movement settings to the vehicle system (2502). Multiple operators in the remote control system (2512) can remotely control the movement of the vehicle system (2502). For example, multiple operators can remotely control several different moving heavy vehicles (for example, trains, boats, automobiles or the like).
[0303] The remote control system (2512) includes a control mediation system (2516) (corresponding to the control mediation system (2016) in Figure 20). The control mediation system (2516) represents a hardware circuit that includes and / or is connected to one or more processors (for example, microprocessors, controllers, field programmable port arrays, integrated circuits or the like). The remote control system (2512) is operatively connected to the control mediation system (2516) by a communication link (2530). The communication link (2530) can represent a wired or wireless connection. In addition, the control mediation system (2516) is connected wirelessly to the OVCS (2514) on board the vehicle system (2502).
[0304] The remote control system (2512) is separate from the
Petition 870190039552, of 04/26/2019, p. 295/339
127/136 vehicle system (2502) over a distance (2526). The distance (2526) can be 50 meters, 500 meters, 500 kilometers, 5000 kilometers or something like that. The distance (2526) between the vehicle system (2502) and the remote control system (2512) can be beyond a line from an operator's location from the remote control system (2512) to the vehicle system (2502), span different time zones, span different geographic locations (for example, different city, county, state, country) or something like that. For example, a remote control system operator (2512) can control the movement of the vehicle system (2502) when the remote control system operator (2512) is located in New York and the vehicle system (2502) is located in Utah.
Alternatively, the distance (2526) can be within a line from a location of an operator from the remote control system (2512) to the vehicle system (2502). For example, the distance (2526) can be less than 50 meters.
[0305] The remote control system (2512) is communicatively connected to the vehicle's OVCS (2514) (2504) through the communication links (2518, 2520, 2522, 2530) established between the remote control system (2512) and the system vehicle (2502). For example, the remote control system (2512) communicates control signals to the control mediation system (2516) over the communication link (2530). The control mediation system (2516) communicates the control signals to a first satellite (2510a) over the communication link (2518). The first satellite (2510a) communicates the control signals to a second satellite (2510b) over the communication link (2520). The second satellite (2510b) communicates the control signals to the OVCS (2514) via the communication link (2522). Optionally, less than two or more than two satellites can be used to communicate signals between the remote control system (2512) and the vehicle system (2502). Additionally or alternatively, the

128/136 vehicle (2502) can communicate with the remote control system (2512) with relays of terrestrial communications (for example, radio towers). Optionally, the vehicle system (2502) and the remote control system (2512) can communicate via communication links established between one or more satellites and / or one or more radio towers, or the like. Additionally, the remote control system (2512) is communicatively connected to the OVCS (2514) via the communication link (2530) established between the remote control system (2512) and the vehicle system (2502). For example, the control mediation system (2516) communicates control signals between the remote control system (for example, over the communication link (2530)) and the OVCS (2514) (for example, over the communication links (2518 , 2520, 2522)).
[0306] The remote control system (2512) communicates control signals to the vehicle system (2502) via communication links (2518, 2520, 2522, 2530) in order to remotely control the movement of the vehicle system (2502) to the as the vehicle system (2502) moves along the route (2508). The control signals dictate the operational movement settings of the vehicle system (2502) which include one or more of a degree of acceleration setting, a brake setting, speed setting or the like.
[0307] The one or more processors of the control mediation system (2516) communicatively connect the remote control system (2512) disposed outside the vehicle system with the OVCS (2514) disposed on board the vehicle system (2502 ). The one or more processors in the control mediation system (2516) mediate a process of transferring control of movement from the vehicle system (2502) from the remote control system (2512) to the OVCS (2514) or from the OVCS (2514) for the remote control system (2512). For example, the mediation system for
Petition 870190039552, of 04/26/2019, p. 297/339
129/136 control (2516) mediates (eg manage, arbitrate or the like) which system controls the vehicle system (2502) to ensure that the control of the movement of the vehicle system is controlled by a single system at a given time.

In addition, when the movement control of the vehicle system (2502) is managed by the OVCS (2514) (manually or autonomously), the vehicle system (2502) cannot be controlled by the remote control system (2512).
[0308] Vehicle system movement control (2502) can transfer from the remote control system (2512) to the OVCS (2514) or from the OVCS (2514) to the remote control system (2512) based on a location , a vehicle system condition (2502), or an operator request and / or condition. The location is a designated geographical area or a designated segment of the route (2508) that is known a priori or calculated according to some trail and / or region characteristics. For example, these areas can be based on population density, track equipment locations, level crossing locations, vehicle workplaces (for example, picking up or adjusting vehicles), a designated practice area for manual system control vehicle (2502), or something like that. The condition may be a failure state of the vehicle system (2502), it may be a loss of communication between the vehicle system (2502) and the remote control system (2512), it may be an increase or decrease in a rate of fuel consumption above a designated non-zero threshold, or the like. The operator's request and / or condition can be based on an operator's level of agility on board the vehicle system (2502) or the
Petition 870190039552, of 04/26/2019, p. 298/339
130/136 remote control system operator (2512), a work break and / or stop assigned to one or more operators, or something like that.
[0309] The remote control system (2512) is configured to remotely control the movement of the vehicle system (2502) by sending control signals to the OVCS (2514) on board the vehicle (2504) through the control mediation system ( 2516). Additionally, the OVCS (2514) is configured to control the movement of the vehicle system (2502) one or more autonomously or manually by an operator on board the vehicle system (2502). The one or more processors in the control mediation system (2516) control which of the remote control system (2512) or OVCS (2514) controls the movement of the vehicle system at any given time. Additionally, the control mediation system (2516) mediates the transfer of control of movement from the vehicle system from the remote control system (2512) to the OVCS (2514) or from the OVCS (2514) to the control system remote control (2512).
