    FIELD OF THE INVENTION The present invention relates to vehicle roofs, and in particular to a method, device and system for supporting the creation of vehicle roofs among a variety of vehicles. The technology is also transferred to a computer program and a computer program product.
    Background of the Invention Cooperative 'Cooperative 'SaIlan knows a vehicle butn that there are other vehicles nearby with which you can shape vehicle stays to save fuel. It can be, for example, vehicles that have the same destination or a large part of the route through. This meant that few vehicle roofs could be created on the road, even though the vehicles were equipped with a cruise control for vehicle roofs.
    It is an object of the invention to provide a tool which can support the creation of vehicle stays with vehicles which are already on the move.
    Summary of the Invention According to a first aspect, the above-described object is achieved by a method for supporting the creation of vehicle roofs among a plurality of vehicles. The method comprises: - receiving information indicating a position for each vehicle in the plurality of vehicles; 2 categorize the vehicles into the crowd into different categories based on a grouping for each vehicle, where the grouping indicates whether the vehicle is a single vehicle or already belongs to a vehicle tag; determine a distance between at least two groupings; - determining a profitability parameter p indicating whether it is profitable to form a vehicle roof with the two groupings based at least on the distance between the two groupings; analyze whether the profitability parameter 13 meets a profitability criterion; and generating a vehicle tag signal 9 based on the result of the analysis.
    Through the method, you can get a snapshot of where all the vehicles in a crowd are in the current situation. It can then be decided whether it is profitable for two or more vehicles in the crowd to form vehicle roofs. The method provides a tool to be able to coordinate vehicles to form vehicle stays when the vehicles are already on the move. The method can result in more vehicle struts that provide industry savings. The method also achieves a easier and / or faster way of forming vehicle roofs by reducing the amount of calculations and data in relation to prior art methods.
    According to one embodiment, a distance between at least two groupings was based on the respective positions of the groupings. According to an embodiment, the position of a vehicle can be its geographical position. According to another embodiment, the information indicating the position of a vehicle may be a relative distance. By knowing one of the geographical position of the vehicles, the position of the other vehicle can then be determined because the relative distance between them is edge.
    According to one embodiment, the method comprises determining said distance between groupings within the same category. In this way, it can be determined whether it is profitable to form vehicle roofs with vehicles in the multitude of single vehicles, 30 with vehicle roofs with two vehicles, vehicle roofs with three vehicles, etc. 3 According to one embodiment, the said categories include the category "single vehicle", which meant that a grouping in the category comprises a vehicle and that the vehicle has at least a distance d1 to a nearest vehicle in the same corphal and / or which has the same correction. According to one embodiment, groupings in the category "single vehicle" are handled for groupings in the remaining categories. By "handling" is meant that you first evaluate all vehicles that are solitary vehicles, in order to determine whether they can form vehicle roofs with any other vehicle or vehicle roof. For example, the distance between single vehicles, ie vehicles classified as single vehicles and whose grouping includes a vehicle, is first determined, and the profitability of forming vehicle stays between these vehicles is determined. In this way, one can determine whether it is profitable to form vehicle roofs with vehicles in the crowd that are solitary vehicles. Then you can determine the distance between single vehicles and groupings that include two or more vehicles, and determine the profitability of forming vehicle stays between these vehicles.
    According to one embodiment, said categories comprise the category "vehicle struts with two vehicles", which meant that a grouping in the category comprises two vehicles which have a distance between the vehicles which is less than or equal to a distance d1. According to a further embodiment, the method comprises that groupings in the category "vehicle struts with two vehicles" are handled after groupings in the category "single vehicle", but for groupings in the remaining categories. By "handling" is meant evaluating all groupings with two vehicles, in order to determine whether they on a profitable sail can form vehicle roofs with the flag of another grouping with one, two or more vehicles. By handling these groupings after groupings with single vehicles, one can get used to the fact that the single vehicles are coordinated to vehicle roofs, and thus there will be none in the flag category with groupings with more vehicles.
    According to a further embodiment, said categories comprise the category "vehicle stays with three vehicles", which meant that a grouping in the category comprises three vehicles which have a distance between the vehicles which is less than or equal to 4 a distance c11.

    According to a further embodiment, the method comprises determining a front grouping and a rear grouping of the two groupings. The rear grouping is subsequent to the front grouping in the direction of travel. Thus, for example, one knows which of the groupings (the rear) one is going to catch up with another grouping (the front one) when determining a profitability parameter 13. According to another embodiment, instead the front grouping can be configured to slow down and catch up rear grouping. According to a further embodiment, the embodiments can be combined, so that the front grouping slows down its speed while the rear grouping increases its speed to catch up with the front grouping.
    According to one embodiment, the method comprises determining a distance d2 to a destination for the front grouping, and determining a profitability parameter 13 indicating whether it is profitable to form a vehicle roof with the two groupings also based on the distance d2 to the destination for the front grouping. In this way, one can take into account the distance that remains to the destination when determining a profitability parameter 13.
    According to a further embodiment, the method comprises determining a profitability parameter 13 which indicates whether it is profitable to form a vehicle roof also based on a cost of changing the vehicle roof based on an increased speed and / or an estimated time for the rear grouping to catch up. the front grouping. In this way, one can also include the cost that arises when the vehicle roof is actually to be formed when determining the profitability parameter 13.
    According to a second aspect, the object is achieved with a device for supporting the creation of vehicle roofs among a multitude of vehicles. The device comprises a map unit with map data, a processor unit and a memory unit which is connected to the processor unit.

    According to an embodiment, the device is arranged to determine said distance between groupings within the same category.
    According to one embodiment, said categories comprise the category "single vehicle", which meant that a grouping in the category includes a vehicle and that the vehicle has at least a distance di to a nearest vehicle in true coral and / or which has the same correction. According to a further embodiment, the device is arranged to treat groupings in the category "single vehicle" before groupings in the remaining categories.
    According to one embodiment, said categories comprise the category "vehicle stays with two vehicles", which meant that a grouping in the category comprises two vehicles which have a distance between the vehicles which is less than or equal to a distance di. According to a further embodiment, the device is arranged to treat groupings in the category "vehicle stays with two vehicles" after groupings in the category "single vehicle", but for groupings in the remaining categories.

    Fig. 2 shows an example of a vehicle according to Fig. 1.
    Fig. 3 illustrates a system with an apparatus according to an embodiment of the invention.
    Fig. 4 illustrates a flow chart of the method according to one embodiment.
    Figs. 5A-5C show an example of how vehicles along a road in Fig. 1 are formed in vehicle struts according to an embodiment of the invention. Fig. 6 shows a diagram illustrating a payload truth analysis for changing vehicle struts for four vehicles.
    Detailed Description of Preferred Embodiments of the Invention Fig. 1 shows a map 1 with a number of vehicles 3, preferably trucks, traveling along a carriage between different cities 2. The cities 2 are marked with filled circles, and the vehicles 3 with unfilled circles. An object of the invention is to facilitate and support the creation of vehicle stays along these roads when the vehicles 3 are already on the road. Being "on the move" meant that vehicle 3 had started its -lard Than a starting point for a destination. A starting point can be a physical place for a farm, a unloading or pick-up place, a resting place or the like. A destination can be a final destination for the vehicle 3, but also has the location of a carriage node, a carriage shell, an intersection or the like. The starting point and different destinations can, for example, be specified in geographical coordinates.
    Fig. 2 shows an example of how a vehicle 3 shown on the cover in Fig. 1 can be equipped. The vehicle 3 shown is in the form of a truck or tractor with a chassis 9 and two pairs of wheels 10A and 10B. The truck shown has only as an example, and the vehicle 3 can instead be, for example, a passenger car, a work vehicle or the like. The truck may also have one or more slacks attached to it. The vehicle 3 is equipped with a computer unit 4, for example in the form of a control unit 4 and a positioning unit 5. The positioning unit 5 can for example be configured to receive signals from a global positioning system such as GNSS (Global Navigation Satellite System) such as GPS (Global Positioning System) , GLONASS, Galileo or Compass. Alternatively, the positioning unit 5 may be configured to receive signals Iran, for example one or more detectors in the vehicle 3 which supply relative distances to, for example, a car node, vehicles in the vicinity or the like with a known position. Based on the relative distances, the positioning unit 5 can then determine the vehicle's own position. A detector can also be configured to detect a signature in, for example, a car node, the signature representing a certain position. The positioning unit 5 can then be configured to determine its position by scanning the signature 9. The positioning unit 5 can instead be configured to determine the signal strength in one or more signals Than several base stations and / or car nodes etc. with kand position, and thereby determine the position of the vehicle by triangulation. Of course, the above techniques can also be combined to ensure the position of the vehicle. The positioning unit 5 is configured to generate a position signal containing the position of the vehicle, and to transmit this to one or more units in the vehicle 3. The vehicle 3 may also be provided with a unit 13 for wireless communication. The unit 13 is configured to act as a receiver and transmitter of wireless signals. The unit 13 can receive wireless signals from other vehicles and / or wireless signals Than the infrastructure around the vehicle 3, and true wireless signals to other vehicles and / or wireless signals to the infrastructure around the vehicle 3. The wireless signals may include vehicle parameters from other vehicles, e.g. geographical position, destination, final destination, selected route, etc. A wireless signal usually also contains a vehicle identity, so that it is possible to identify which vehicle 3 the wireless signal originates from. The vehicle 3 can also be equipped with a map unit 6 with a digital map of at least the vague that the vehicle 3 is to cross. According to an embodiment, the driver can indicate an end destination and the map unit 6 can then, by knowing the current position of the vehicle, provide relevant map data about the coming carriage between the current position and the final destination. Furthermore, the vehicle 3 can be provided with a display unit 7 through which instructions can be conveyed to the driver. For example, the display unit 7 is arranged to display instructions visually via a display in the display unit 7. According to another alternative, the display unit 7 is arranged to display instructions audibly via a loudspeaker in the display unit 7. The display unit 7 may also be arranged to display instructions both visually and audibly. The vehicle 3 also comprises a control unit 8 which is arranged to control the speed of the vehicle. According to one embodiment, the control unit 8 can be a cruise control. The vehicle 3 may also be provided with one or more detectors which are generally shown as a detector unit 14 for sensing the surroundings, for example a radar unit, laser unit, tilt feeder, etc.
    The detector unit 14 is configured to sense a parameter, for example a relative distance to another vehicle. The detector unit 14 is further configured to transmit the detector signal to one or more units in the vehicle 3.
    The vehicle 3 communicates internally between its various units through, for example, a bus, for example a CAN bus (Controller Area Network) which uses a message-based protocol. Examples of other communication protocols that can be used are TTP (Time-Triggered Protocol), Flexray and others. In this way, signals and data described above can be exchanged between different units in the vehicle 3. For example, signals and data can instead be transmitted wirelessly between the different 10 units.
    Each vehicle 3 can thus be provided with a unit for wireless communication 13.
    The vehicles in the crowd can, according to one embodiment, communicate with each other by vehicle-to-vehicle communication or other means such as through mobile communication devices, via an application in a communication device or via a server, and to infrastructure in the form of vehicle-to-infrastructure communication. Infrastructure can be, for example, a carriage node, server or the like. Carriage nodes, server etc can also be equipped with a device for wireless communication (not shown).
    To support the creation of vehicle stays, a device 11 shown in Fig. 3 can be implemented in the vehicle 3, a server, a car node, a computer in a haulage company, in an FMS (Fleet Management System) or the like. The device 11 is part of a system for supporting the creation of vehicle roofs. The device 11 comprises a computer unit 4, which may for instance be an electronic control unit 4 if the device is implemented in a vehicle 3. The computer unit 4 may instead be a part of a server, a part of a car node or the like. The computer unit 4 comprises a processor unit 10 and a memory unit 9 which is connected to the processor unit 10. On the memory unit 9 there is a computer program P stored, which can cause the computer unit 4 to perform the steps according to the method described herein. According to one embodiment, the memory unit 9 is part of the processor unit 10. The processor unit 10 may be constituted by one or more CPUs (Central Processing Unit). The memory unit 9 may 11 comprise a non-volatile memory, for example a flash memory or a RAM (Random Access Memory). The device 11 also comprises the map unit 6 with map data, as previously explained. The memory unit 9 includes instructions for shaping the processor unit 10 to execute a number of steps which will be explained in the following.
    Fig. 3 shows a number of positioning units 5A-5D, each having its physical location in its respective vehicle 3. Fig. 3 shows four positioning units to illustrate the principle, but more or fewer positioning units can be found. The positioning units 5A-5D each generate a positioning signal which indicates the geographical position of the vehicle 3 in which the positioning device 5A-5D is located. These positions can then be sent via, for example, wireless communication to the computer unit 4. If the computer unit 4 is in a vehicle, the vehicle's position is sent via, for example, an internal network to the computer unit 4. One or more positions may instead be positions that are reported to the vehicle's respective farm. The device 11 can then retrieve information about the positions Than a computer or server Than akeriet where the positions are stored. The processor unit 4 has access to the geographical positions for the vehicles in which the zone comprises four vehicles (A1, Fig. 4). Using the geographical positions of the various vehicles 3 and the map data of the map unit 6, the processor unit 10 can be configured to create a snapshot of where the vehicles are in the crowd and possibly where they are on the road. According to one embodiment, the positions of the vehicles can also be determined by feeding relative distances between the vehicles. The control unit 4 can then obtain information from one or more detector units 14 about one or more relative distances and use it in the calculations. It may also be arranged to determine the geographical positions of one or more vehicles based on measured relative distances. Based on a profitability analysis, the control unit 4 generates a vehicle tag signal 13 which, depending on the configuration, can be sent to a display unit 7 and / or a control unit 8 in one of the vehicles one of the groupings. Then a number of steps are performed which will be explained below in connection with the flow chart in Fig. 4. 12 In one step, the vehicles are categorized into the crowd in different categories based on a grouping for each vehicle, where the grouping indicates whether the vehicle is a single vehicle or already belongs a vehicle stay (A2). Since the geographical position of each vehicle can be known, the distance between the vehicles can also be calculated.
    Alternatively, the distance between vehicles is obtained directly through relative feeds. As a sub-step to A2, the distance between the vehicles is determined in the crowd, to see how they are grouped. You can then see which vehicles are closest to each other, and arrive at how the vehicles are grouped. A grouping can include only one vehicle, two vehicles, three vehicles or several vehicles. According to an embodiment, information about a vehicle belonging to a vehicle roof can also be obtained through wireless overford data with the vehicle's vehicle roof affiliation. This data is linked to the vehicle identity of the vehicle. The vehicle roof affiliation can indicate how many vehicles the vehicle roof includes. According to another embodiment, the device can determine how many vehicles are in the same vehicle roof by determining how many vehicles have the same vehicle roof affiliation. According to one embodiment, said categories include the category "single vehicle", which means that a grouping in the category includes a vehicle and that the vehicle has at least a distance di to a nearest vehicle in true coral and / or which has the same direction of travel. According to another embodiment, said categories include the category "vehicle struts with two vehicles", which meant that a grouping in the category includes two vehicles which have a distance between the vehicles which is less than or equal to a distance di in the same corphal and / or which has the same correction. In addition, the two vehicles have at least a distance di to an additional closest vehicle in the same corridor. According to a further embodiment, said categories comprise the category "vehicle stays with three vehicles", which meant that a grouping in the category comprises three vehicles which have a distance between the vehicles which is less than or equal to a distance di in the same coral and / or which has the same correction. In addition, the three vehicles have at least a distance di to an additional nearest vehicle in the same coral and / or which has the same correction. The distance di is according to an embodiment between 80 m -100 m, for example 80, 90 or 100 m. To find out if the vehicles are in the same coral, one can use positions Than the vehicles for a period of time, and determine a correction for each vehicle 13 with the help of respective positions during the time period. You can instead use a so-called "heading" which can be included in the information about the vehicle's position. A "heading" or "direction" indicates the direction in which the vehicle is moving. For example, the positioning unit 5 may be arranged to also generate data on the correction of the vehicle. The directions can then be compared to determine if the vehicles are traveling in essentially the same direction. According to another embodiment, the direction is already known as a single parameter sand together as the geographical position of the vehicle. Map data can also be used to determine whether the vehicles are in the same direction and / or have the same direction.
    In a further step, a distance is determined between at least two groupings based on the respective position of the groupings (A3). For example, the position can be a geographical position and with the help of map data, the distance between the groupings can be determined. Alternatively, a relative distance between the groupings is fed. By distance is meant the distance between the groupings along the scales that connect the positions of the vehicles, and on which the vehicles can travel. According to one embodiment, the step comprises determining said distance between groupings within the same category. In this way, the distance between two single vehicles can be determined, the distance between groupings with two vehicles can be determined, and groupings with two vehicles can be determined. According to one embodiment, groupings in the "single vehicle" category are handled for groupings in the remaining categories. In this way, one can identify which vehicles are "alone", i.e. which vehicles have a minimum distance d1 to its nearest vehicle. According to one embodiment, groupings in the category "vehicle struts with two vehicles" are handled according to groupings in the category "single vehicle", but for groupings in the remaining categories. By first handling single vehicles and getting them to form vehicle roofs with groupings with one or more vehicles, and then getting groupings that contain two vehicles to form vehicle roofs with other vehicle roofs, Or said according to studies the greatest savings.
    After a distance between two groupings has been determined, a profitability parameter 13 is determined which indicates whether it is profitable to form a vehicle roof with the two groupings based at least on the distance between the two groupings (A4). It is then analyzed whether the profitability parameter 6 meets a profitability criterion (A5) and a vehicle take-off signal a is generated based on the result of the analysis (A6). According to one embodiment, a vehicle tag signal 9 is generated which includes an instruction to form a vehicle tag. According to another embodiment, a vehicle tag signal 9 is generated which comprises a control signal to at least one vehicle control unit. The vehicle control unit can be, for example, a cruise control, and the control signal can be a speed reference to the cruise control. According to a further embodiment, an interactor, for example the haulier, notifies one of the groupings that they must follow another grouping and form vehicle roofs with it, when the interactor finds out the result of the analysis and it states that it is profitable to form vehicle roofs. The vehicle tag signal 9 can be sent to the grouping via vehicle-to-vehicle communication, vehicle-to-infrastructure communication or WLAN (Wireless Local Area Network). The vehicle stay signal 9 can be sent to the driver, for example to an application in a computer in the cab. The computer can be, for example, the driver's telephone.
    By a "plurality" is meant a number of vehicles whose geographical positions and / or relative distances between each other are evaluated in order to be able to know from where it is profitable to form vehicle roofs with the vehicles. A quantity can be, for example, all vehicles traveling along a certain stretch of road in the same direction, all vehicles from a certain haulage company, all vehicles in a certain region or all vehicles driving past a certain carriageway for a certain time in the same direction and registered by the carriage node. A quantity can also be all vehicles morn a certain region or vagracka Than a special vehicle, which has the same direction as the special vehicle et.
    According to one embodiment, a profitability parameter 6 is determined in the form of the distance 30 between the two groupings. The distance can, for example, be analyzed by comparing it with a predetermined or projected maximum value that the distance may have. If the distance is less than the largest value, then a vehicle stay signal a is generated which, for example, indicates a speed which one of the two vehicles must have in order for the vehicles to come close to each other so that they can change a vehicle stay. According to one embodiment, the vehicle tag signal p is sent to at least one of the two arrays.
    An aystAnd between two groupings is determined as the smallest aystand between the two groupings. If a grouping consists of several vehicles, then the distance Than is determined by the front vehicle and from the rearmost vehicle in the grouping, respectively, depending on where the other grouping is located.
    According to one embodiment, the method comprises determining a front grouping and a rear grouping of the two groupings. By "front grouping" is meant the grouping of vehicles which is furthest in the correction among the two groupings. By "rear grouping" is meant the grouping of vehicles that is furthest back in the correction among the two groupings. A front grouping and a rear grouping can be determined, for example, by comparing the positions and directions of the groupings with each other. The vehicle tag signal (f) can then be sanded to the rear array of those arrays, and for example indicate a speed that the rear array must maintain to catch up with the rear array. According to another embodiment, the vehicle tag signal is sent to the front grouping of those groupings, and may indicate, for example, a speed which the front grouping must maintain in order for the rear grouping to be able to catch up with the front grouping. According to a further embodiment, a vehicle tag signal cp is sent to the [Dada arrays. The contents of them can be different, for example instructions on a lower speed than the current speed to the front grouping, and instructions on a higher speed than the current speed to the rear grouping. The speed or speeds can be speeds determined by the device and / or the system. According to one embodiment, the speed that the rear grouping must maintain in order to catch up with the front grouping can be a predetermined speed. According to one embodiment, the speed that the front grouping must maintain in order for the rear grouping to catch up with the front grouping can be a predetermined speed. According to another embodiment, the speed or velocities can be determined in profitability calculations and used in the profitability analysis. For example, the speed or speeds required by the groupings in order for the groupings to be able to form vehicle roofs within a certain time and / or distance can be determined, and conveyed to the groupings. According to an embodiment, the distance between the groupings is determined as the distance between the rearmost vehicle in the first grouping and the front vehicle in the rear grouping.
    A grouping of several vehicles can be arranged to receive the vehicle tag signal cp via the front vehicle in the grouping, for example the leader vehicle, which then regulates the remaining vehicles in the grouping based on the vehicle tag signal cp. Alternatively or in combination, all vehicles in the grouping are arranged to receive the vehicle stay signal.
    In most cases, a vehicle's haulier has information about which destinations the vehicle 3 will pass, and also which is the final destination of the vehicle. The driver of the vehicle 3 can also, with the aid of a route planner in the vehicle 3, determine which lane the vehicle 3 is to take, and which destinations it will pass under the lane. The final destination is in most cases kand. A distance d2 from the current position of the vehicle or grouping to the flag of its destinations, for example its final destination can then be determined based on the current position of the vehicle and the position for the current destination. According to one embodiment, the method comprises determining a distance d2 to a destination for the front grouping, and determining a profitability parameter 13 indicating whether it is profitable to form a vehicle roof with the two groupings also based on the distance d2 to the destination for the front grouping. If, for example, the front grouping has a distance d2 to a selected destination, and the rear grouping can, by maintaining a maximum permitted speed or other speed, catch up with the front grouping before the front grouping has reached the selected destination, then it can be considered profitable. to form a vehicle stay with the front and rear grouping. According to 17, the computer unit 4 is arranged in an embodiment to determine how long distance d3 the rear grouping needs to wear in order to reach the front grouping and compare the distance with the distance d2. If d3 <d2, the computer unit is arranged to generate a vehicle stay signal indicating to the rear grouping that it should catch up with the front grouping, or to generate a vehicle stay signal in the form of a control signal with the highest permitted speed or other speed. The speed can be a higher speed than the current speed set by the haulier, the device, the system or by the driver. It is this speed that is also used in the profitability analysis.
    Figures 5A to 5C illustrate a scenario when first in Fig. 5A single vehicles are located and then the single vehicles are formed into vehicle roofs with two vehicles in conventional vehicle roofs. Thereafter, the vehicle stays with two vehicles are joined together to form a vehicle stay with four vehicles. The figures show a carriage node 4 or server 4 which organizes and supports the formation of vehicle roofs. The plurality of vehicles consists of four vehicles 31, 32, 33 and 34. In more detail, said in Fig. 5A, the vehicles 31 and 32 are illustrated with the distance d4 between the vehicles, the vehicles 33 and 34 with the distance d6 between each other, and the distance d5 between the vehicles 32 and 33. Since d5 is larger than both d4 and d6, vehicles 31 and 32 are considered to be closest to each other, and vehicles 33 and 34 are closest to each other. All other vehicles have a greater distance than d5 from vehicles 31, 32, 33 and 34. Since d4 is larger than d1, vehicles 31 and 32 respectively are grouped independently in the category "single vehicle". Since d6 is larger than d1, vehicles 33 and 34, respectively, are also grouped independently in the category "single vehicle". Profitability parameters [3 are then determined to indicate whether it is possible to form vehicle roofs between vehicles 31, 32, 33 and 34, all of which are placed in the "single vehicle" category. Since it is desirable to first form vehicle roofs between single vehicles with the least distance from each other, a rear vehicle roof consisting of vehicles 31 and 32, and a vehicle roof consisting of vehicles 33 and 34, are formed, as shown in Fig. 5B.
    Then Ors a new categorization of the groupings, where it is concluded that vehicles 31 and 32 belong to the same grouping because the distance d4 between them is smaller than d1, and now belongs to the category "Vehicle struts with two vehicles". Similarly, it is concluded that vehicles 33 and 34 belong to the true grouping since the distance d6 between them is smaller than d1, and now belongs to the category "Vehicle struts with two vehicles". Then a latency parameter 13 is determined between the groupings which indicates whether it is wont to form vehicle struts between the groupings. In this case, it is lont, and a vehicle stay signal is generated which indicates to the rear grouping that they should 6 speed, or control their speed, said that they hail the maximum allowed speed and catch up with the front grouping and form a common vehicle stay with four vehicles.
    A profitability parameter can be determined in different ways. Two embodiments have already been described above, in which one thing is the profitability parameter 13 the distance between the two groupings. In the second embodiment, the latency parameter 13 is a distance d3 which indicates how far distance the rear grouping needs to wear to reach the front grouping. Instead of a straight d3, the profitability parameter 13 can instead be specified as a time t3 that it takes for the rear grouping to take to reach the front grouping.
    The rear grouping then preferably has a maximum permitted speed.
    A vehicle 3 such as an Icor truck is used at a predetermined speed, for example 80 km / h. A maximum permitted speed can be, for example, 90 km / h. According to one embodiment, the device 11 and the method do not need to receive information about the speed of the vehicles, but can assume that the vehicles Icor at 80 km / h. If the distance between the groupings is known, you can calculate the distance d3 or the time t3 that the rear grouping needs to wear to catch up with the front grouping as the rear grouping runs at the maximum permitted speed, for example 90 km / h. According to another embodiment, one has knowledge of the actual speeds of the vehicles and can base the calculations on it. By catching up is meant that the rear grouping comes closer or equal to the distance d1 from the front grouping.
    The method can continue to support the creation of vehicle roofs as long as it is profitable, and as long as there are a large number of vehicles to create vehicle roofs with. In Fig. 6 a diagram shows a further way of determining a profitability parameter p. In the diagram it is assumed that the distance between the vehicles is equidistant and that the quantity contains four vehicles. On one axis a quotient is shown at which is the coordination cost divided by the cost of not coordinating. The coordination cost can be determined as the cost involved in increasing the speed of the rear grouping to catch up with the front grouping. The cost of not coordinating can be determined as the cost of not forming in vehicle roofs. According to one embodiment, the cost of not coordinating is stated in finished tables. For example, there are standard tables that indicate how much energy can be saved by having none in a vehicle roof, depending on the location of the vehicle in the vehicle roof. On the second axis, a distance ratio k2 is indicated which is the distance d2 to a destination for the front grouping divided by the distance between the front and the rear grouping. s1 shows the graph when the vehicles are first coordinated in pairs, and then maintain the speed. s2 shows the graph when the vehicles the four vehicles are coordinated simultaneously and forms a large vehicle roof with four vehicles, and s3 shows the graph when the vehicles are first coordinated in pairs and then coordinated again to create a larger vehicle roof with four vehicles. In the chart, alit over is considered unprofitable, and below unprofitable. It is therefore most rewarding to primarily form vehicle roofs between single vehicles. However, if the distance is too short to the destination, it may be better not to form a vehicle roof ails. If, on the other hand, it is far to the destination, it can be good to form longer vehicle roofs. The method may thus comprise determining a profitability parameter which indicates whether it is profitable to form a vehicle roof also based on at least some of the distance between the two groupings or a cost of forming the vehicle roof based on an increased speed and / or an estimated time. for the rear grouping to catch up with the front grouping.
    The present invention is not limited to the embodiments described above. Various alternatives, modifications and equivalents can be used.
    Therefore, the above-mentioned embodiments do not limit the scope of the invention, which is defined by the appended claims. 21
