    Descriptive Report of the Invention Patent for: “BAND CHANGE WARNING SYSTEM”.
    FIELD OF THE INVENTION:
    [001] The present invention generally relates to a lane change warning system for a vehicle. In particular, the lane change warning system includes exit functionality integrated into a corresponding vehicle seat.
    BACKGROUND OF THE INVENTION [002] During the operation of a motor vehicle, a driver may become distracted or drowsy, which causes the vehicle, while still generally under the driver's control, to move out of the lane the vehicle is on. going through. Such an unintentional or potential lane change may ultimately result in the vehicle leaving the highway, collision with a vehicle traveling on an adjacent lane or loss of control of the vehicle by the driver through overcorrection when he becomes aware of the lane change. Various systems can monitor a vehicle's trajectory and detect a lane change and alert the driver when necessary. However, existing lane change warning systems may not provide an appropriate indication of a real or potential lane change for a driver. Consequently, further advances in such systems may be desired.
    SUMMARY OF THE INVENTION [003] In accordance with an aspect of the present invention, a lane change warning system for a vehicle includes a positional input device and a seat that has an inflatable bladder in it and a vibrational unit coupled to the bladder. A controller is communicatively coupled to the positional input device and the vibrating unit and includes a set of electronic circuits programmed to detect a change of track based on a signal from the positional input device and to cause the vibrational unit to vibrate in response to this. .
    2/14 [004] According to another aspect of the present invention, a vehicle seat assembly includes a seat base, a backrest, a cover material disposed on the backrest and the seat base. An inflatable bladder is arranged in at least one of the seat base and backrest, below the cover material, and is configured to move between a first position, in which the bladder is deflated, and a second position, in which the bladder is inflated. A vibrational unit is attached to the bladder.
    [005] According to another aspect of the present invention, a motor vehicle includes a positional input device, a seat that has an inflatable bladder in it and a vibrational unit coupled to the bladder, a lane change warning controller communicatively coupled to the input device and the vibrational unit. The controller includes electronic circuitry programmed to detect a change of track based on a signal from the positional input device and to cause the vibrating unit to vibrate in response to this.

Therefore, the specific dimensions and other physical characteristics relating to the modalities described in this document should not be considered as limiting, unless the claims express otherwise.

    [016] Referring to Figure 1, reference number 10 generally designates a lane change warning system. The lane change warning system 10 can generally be used on a vehicle 12 (as shown in Figure 2) and can include a positional input device, which can be in the form of an optical imaging device 14 (which can be in the form of camera or similar), positioning system receiver
    4/14 global (“GPS”) 16, yaw sensor 18 or similar. System 10 may also include a seat 20, which includes an inflatable bladder 22 therein and a vibrational unit 24 (Figure 3) coupled to bladder 22. A controller 26 is communicatively coupled to the positional input device (like at least one of the optical imaging device 14, GPS receiver 16 and yaw sensor 18) and vibration unit 24, and includes electronic circuitry (such as processor 30) programmed to detect a vehicle lane change 12 based on a signal of the positional input device (such as at least one of the optical imaging device 14, the GPS receiver 16 and the yaw sensor 18) and to cause the vibrational unit 24 to vibrate in response to this.
    [017] As additionally shown in Figure 1, the seat 20 can be an assembly of several components, including the base or seat cushion 32, the backrest 34, which is rotatably coupled to the cushion 32, and the headrest 35 which is coupled (and can be adjusted in relation to) the backrest 34. The seat assembly 20 can also include cover material 36 in the form of several pieces of foam or other undercoat and upholstery material for the seat 20, which can include various fabrics or natural or synthetic leather. The cover material 36 can include several segments of it that can be attached together and collectively attached to at least one of the cushion 32, the backrest 34 and the headrest 35 and / or attached to one of the cushion 32, the backrest 34 and headrest 35 in individual units. The seat assembly 20 can also include several of the aforementioned bladders 22, which can be positioned at various strategic locations along the cushion 32, the backrest 34 and / or the headrest 35, and can be independently mobile between an inflated state and a deflated state to allow customization of the contour of both the cushion 32 and the backrest 34 based on the needs or desires of the occupants of the seat 20.
    [018] Bladders 22 can move to the inflated state through the
    5/14 receiving pressurized air from an air source that can be in the form of a pump (which can be specific for individual seat 20 or can be common among numerous seats of similar configuration in vehicle 12) and a network of tubes and connecting pipes that facilitate fluid communication between the pump and the bladders 22 and selectively control the flow of pressurized air supply from the pump to the desired bladders 22. Similarly, additional tubes and pipes can fluidly couple the bladders 22 to one or more vents (not shown) to allow the release of air inside the bladders to move them to the deflated position. In one example, the control of the air flow in and out of the bladders 22 to move them between the deflated position and the inflated and vice-verse position can be controlled by the electronic circuitry that includes several analog switches or digital controls like several electronic circuits, chips and / or microprocessors that can be included in a computer system built into the vehicle 12. In one example, which includes where a computer or the like is used to control bladder inflation and deflation 22, the “deflated” position ”Of the bladders 22 can be a state in which some air remains inside the bladders 22, but so that the bladders 22 are at a lower end of the inflation range of the bladders.
    [019] As also illustrated in Figure 1, an example seat 20 may include numerous bladders 22 that include respective sets of bladders 22 within the lumbar area 38 of the backrest, within the central area 40 of the cushion 32, within the backrest 42 and backrests of the cushion 44 and inside the headrest 35. The bladders 22 within such varying regions of the seat 20 can take a number of shapes that can generally include one or more polymeric membranes (such as plastic), which can be strategically sealed to form chambers . In any such construction, bladders 22 are generally impervious to air, so that the air inside a bladder 22 that is in an inflated state remains at the level of
    6/14 desired inflation.
    [020] As shown in Figures 3-6, several bladders 22 may have one or more vibrational units 24 coupled to them to transmit vibration through them, and also through overlying areas of the cover material 36, in order to be noticeable by a user occupying seat 20. As discussed above, vibrating units 24 can be communicatively coupled to controller 26 so that controller 26 can cause vibrating units 24 to transmit a signal in the form of vibration to a seat occupant 20 in response to a detected change in vehicle 12 from a lane on the highway on which vehicle 12 is traveling. In several examples, it may be desirable that one or more vibrational units 24 are coupled to the bladders 22 which are located within the central area 40 of the pad 32, the lumbar area 38 of the backrest 34 and / or the headrest 35, as a seat occupant 20 is generally constant or almost constant in such areas of seat 20 when driving the vehicle 12. Additionally, it is noted that the inclusion of such vibrational motors 24 coupled to the controller 26 is particularly suitable for use in a vehicle driver's seat 12, as shown in Figure 2.
    [021] As shown in Figures 3 and 4, one or more vibrational units (such as two vibrational units 24, as shown in Figures 3 and 4) can be attached to bladders 22 within the lumbar area 38 of backrest 34. In the example shown, the bladder 22 may include a margin 46 around its edge and outside an associated cell 48 or, otherwise, an inflatable portion thereof. Consequently, bladder 22 can accommodate an orifice 50 therein, without allowing air to escape from cell 48 when bladder 22 is in an inflated state. Consequently, the orifice 50 can receive a closure 52 therethrough, which can connect the bladder 22 to the support 54. In the example shown, the support 54 can be mobilely coupled to the seat frame 56. In such a way, the
    7/14 bladders 22 within the lumbar area 38 can be kept in generally constant contact with the lumbar of a seat occupant 20. As shown in Figure 4, the vibrational units 24 can be coupled to the locks 52 for the purpose of being generally coupled to the bladders 22. Consequently, their vibration, as in the direction of the controller 26, can be transmitted through the closure 52 and to the associated bladder 22, thereby causing the vibration of at least a portion of the bladder 22, with the purpose of being perceptible by a seat occupant 20.
    [022] As can generally be seen in Figures 5 and 6, the vibrating units 24 can include an electric motor 58, which can include a mounting hole 60 (Figure 4) in it, so that the vibrating units 24 are mountable in respective locks 52. Electric motors 58 can be a 12 volt DC motor or the like, and can be configured to rotate an output rod 64 extending from one side thereof. An eccentric weight 62 is mounted on the output rod 64 of the motor 58 so that the rotation of the output rod 64 causes the eccentric weight 62 to rotate, thereby causing the vibration of the vibrating unit 24. As further illustrated in Figure 4, the closures 52 can be made of a resiliently deformable polymeric material, such as nylon or similar, and can be adapted to press and / or pressurize both hole 50 and bladder 22 and through a corresponding hole (not shown) in the backrest support 54. Additionally, the locks 52 may be longer than necessary to join the bladder 22 to the support 54 so that a remaining portion of the lock 52 can be received in the mounting hole 60 of the engine 58. The corresponding portions of the latches 52 can be deformed to facilitate a snap fit in the mounting hole 60 in order to secure the vibrating unit 24 with the latch 52. An example of a suitable latch includes a latch a type commonly called a “Christmas tree” closure, although other mechanical closures, such as threads, pins or the like, can be used.
    8/14 [023] As shown in Figure 7, additional or alternative vibrational units 24 can be coupled to a bladder 22 positioned within the central area 40 of pad 32. Such vibrational units 24 can be similarly attached to bladder 22 by coupling the electric motor 58 to the lock 52, which in turn is used to couple the bladder 22 to the support 66 of the pad 32. In addition, the additional vibrational units 24 can be coupled to the additional bladders 22 inside the seat 20, like the bladders 22 positioned on the backs 44. In the example shown in Figure 7, the bladders 22 positioned inside the backs 44 are coupled between a static projection 68 and a dynamic projection 70, which is movable in relation to the static projection 68. In this way, the movement of the cushion 32 between the deflated and inflated positions causes the movement of the dynamic projection 70 in relation to the static projection 68. Consequently, the bladder vibration 22 within the backrests 44 po to cause the vibration of such a bladder 22, which can be transmitted to the dynamic projection 70 and through an overlying portion of the cover material 36, in order to be perceptible by a seat occupant 20. In general, the backrests 44 can be adjustable in a manner described above so that they can be comfortably positioned in contact with a portion of a leg of the occupant, thereby making the vibration of the backrests 44 perceptible to the occupant of the seat 20. Additional vibrating units 24 can be similarly incorporated into the bladders 22 positioned inside the backrest backs 42. In addition, the additional vibrational units 24 can be coupled to the additional bladders 22 positioned along the seat 20, as desired, including within the headrest 35.
    [024] As shown in Figure 2, system 10 which includes seat 20, can be included in vehicle 12 with seat 20 positioned inside 72 of vehicle 12. As shown, seat 20 is positioned as a driver's seat. vehicle 12 so that seat 20 is positioned adjacent to steering wheel 74 to allow an occupant of seat 20 to control the
    9/14 vehicle movement 12. As previously discussed, system 10 may be in the general form of a lane change warning system, which has the ability to identify a situation in which vehicle 12, as controlled by the seat occupant 20, for example, starts unintentionally changing a lane on which vehicle 12 is traveling. System 10 is additionally capable of alerting the driver to such an unintended lane change so that the driver can correct the vehicle's course 12.
    [025] As shown in Figure 1, controller 26 may include processor 30 and memory 76. In other examples, controller 26 may employ another set of analog or digital control circuits, including an integrated circuit for specific application ( “ASIC'j or other known circuitry to process the input data, update the learned trajectories, execute one or more lane change routines, issue a lane change warning and upload data to one or more central databases. Processor 30 is able to identify a lane change using memory 76, one or more GPS receivers 16, yaw sensor 18 and optical imaging device 14, such as a video camera or similar, according to numerous different modes of operation. In one example, processor 30 can “learn” common path trajectories of vehicle 12 over time with the use of the GP receiver S 16, storing such trajectory trajectories learned in memory 76. During subsequent driving, an instantaneous trajectory of vehicle 12 can be monitored by GPS receiver 16 and, when processor 30 identifies vehicle 12 as traversing along that learned trajectory , the processor 30 can additionally monitor the movement of the vehicle 12 using the GPS receiver 16 in relation to the deviation of such trajectory. In certain situations, deviations from such a trajectory can be identified as a change of track. Additionally, system 10 can monitor a highway on which vehicle 12 is traveling using optical imaging device 14, in
    10/14 regarding identifiable track markers. Similarly, under certain circumstances, the visual identification of one or more of such lane markers by the optical imaging device 14, as moving laterally in relation to the vehicle 12, can be identified as a lane change. Controller 26 can identify a potential range change according to modes of operation other than those described in the present invention.
    [026] Controller 26 may additionally use input from GPS receiver 16, yaw sensor 18, and optical imaging device 14 to indicate that a lane change is intentional. In such a case, controller 26 may determine that a warning is not necessary. For example, the yaw sensor 18 can be used to detect a case where vehicle 12 is making a turn, such as at an intersection or the like, by measuring vehicle rotation rate 12. In one example, if the vehicle yaw rate exceeds a threshold (for example, 0.35 radians per second), controller 26 can determine that a turn is being made and that a lane change warning is not required. In addition, the input of the optical imaging device 14 can determine that the lateral movement of the vehicle 12 occurs in response to a change in trajectory of the vehicle lane itself traveled, and that a lane change warning is not necessary.
    [027] When processor 30 identifies a change in range, for which a warning is desired, processor 30 can send a signal to communication module 28, which can then send a signal to one or more vibration units 24 into seat 20 to activate the bladder 22 or associated bladder 22 vibration. In addition, the communication module 28 can direct an audio system 78 from the vehicle 12 to output an audio signal, and can also send a signal to a visual indicator 80, such as a light on the vehicle instrument panel (not shown) or anywhere in vehicle 12, as part of the lane change notice. In one example
    11/14 additionally, the communication module 28 can be electronically coupled to one or more valves associated with the bladders 22, so that a warning signal in the form of bladder vibration 22 can be implanted making these valves, which can be solenoid valves or the like, pulsate (including both at the inlet and outlet end of the bladder 22) so that vibration of the bladder 22 is achieved by rapid inflation and disinflation thereof.
    [028] In one embodiment, a lane change warning can be implemented by system 10 in response to a lane change detected by processor 30 that simulates the movement of vehicle 12 by an expressway sound signal. Expressway sound signals can generally include physical resources positioned on the shoulders of a road or expressway that are configured to cause a vehicle to vibrate noticeably, such as vehicle 12, when one or more tires pass over them. Many drivers have been conditioned to respond well to the noise and vibration generated within a vehicle that passes over such sound signaling, making the stimulation of such noise and vibration an effective means of potentially communicating a lane change, including when a sound signal does not is located adjacent to the travel range. In one example, the communication module 28 can be configured to cause the vibrational units 24 to rotate at a speed sufficient to generate vibration in the general range of that caused by a vehicle that passes over a sound signal at expressway speeds. In one example, such a frequency can be between about 80 Hz and 115 Hz. Additionally, vibrational units 24 can be selected to include a weight 62 of sufficient mass and an electric motor 58 of sufficient torque to produce such vibration in amplitude. comparable to that of a vehicle passing over an expressway sound signaling. In addition, the communication module 28 can send a signal to the audio system 78 so that the audio system 78 produces a warning
    12/14 audible that can generally replicate the sound within a vehicle that passes over an expressway sound signaling. Such an audio signal may be in the same general range as the vibration implanted by the vibrational units 24 (such as the audio signal that generally corresponds to the frequency of the vibration) and / or may include a pre-recorded or computer generated audio track from a vehicle passing over an audible signal.
    [029] In a triggered example, controller 26 may be able to determine a particular direction in which a lane change is taking place to associate that direction with a corresponding side of vehicle 12 (ie, a driver's side or a passenger). In response to such an identified lane change, processor 30 may direct communication module 28 to send a signal to the particular vibrational units 24 positioned on one side of seat 20 that correspond to the identified side of the lane change. In one example, if processor 30 detects a lane change to the driver's side of vehicle 12, a signal can be sent by communication module 28 to vibrating units 24 located on an external side of seat 20 (that is, still towards the driver's side of the seat 20), including inside the central area 40 of the cushion 32, the lumbar area 38 of the backrest 34 and inside the backrests 42 and 44 positioned on the outside of the seat 20. Additionally, the communication module 28 can direct the audio system 78 to present an audible warning, such as a particular tone, through loudspeakers positioned on a similarly corresponding side of the vehicle 12 which can also direct a visual indicator 80 on that side of the vehicle 12 to present a signal visual warning. The implantation of a lane change warning in accordance with this mode can be implemented with or without the simulation of the expressway sound signaling mentioned above.
