Abstract

A receiver capable of receiving a remote vehicle stop request signal is mounted to a commercial vehicle and connected to the vehicle antilock braking ECU by a vehicle communication bus. The receiver may also be capable of transmitting a signal, thereby allowing the desired vehicle to be isolated. Furthermore, a user input device may be mounted to the vehicle that allows manual input of a park signal. When the park signal has been received by the vehicle ECU, the vehicle braking system is employed, thereby preventing the movement of the vehicle.

Claims

1. A method for stopping a vehicle comprising the steps of:

sending a signal requesting the vehicle to stop via an apparatus remote from the vehicle brake actuating device;

processing the signal within the vehicle antilock braking ECU;

sending a vehicle stop request signal to the vehicle brake system to apply the brakes;

applying the vehicle brake system to stop the vehicle; and

running diagnostic tests, wherein said diagnostic tests determine whether a vehicle stop request signal can be received.

2. The method of claim 1 further comprising the step of receiving the vehicle stop request signal with a receiver.

3. The method of claim 2, wherein said receiver is mounted on a vehicle trailer.

4. The method of claim 1 further comprising the step of communicating the vehicle stop request signal to the vehicle antilock braking ECU via an existing vehicle communication bus.

5. The method of claim 4, wherein said vehicle communication bus is the vehicle Power Line Carrier.

6. The method of claim 1, wherein the vehicle stop request signal is generated manually.

7. The method of claim 6, wherein the vehicle stop request signal is generated from within the vehicle cabin.

8. The method of claim 1, further comprising the step of encoding said vehicle stop request signal.

9. The method of claim 1, further comprising the steps of:

sending a brake release signal; and

releasing the vehicle brake system.

10. The method of claim 1 further comprising the step of generating a vehicle stop request signal when any one of said diagnostic tests determines that a vehicle stop request signal cannot be received.

11. The method of claim 1, wherein said diagnostic tests are performed prior to the release of the vehicle parking brakes.

12. The method of claim 11 further comprising the step of maintaining the vehicle parking brakes when any one of said diagnostic tests determines that a vehicle stop request signal cannot be received.

13. The method of claim 1 further comprising the step of applying the vehicle parking brakes once the vehicle has come to a stop.

14. The method of claim 1, wherein the vehicle is a commercial vehicle.

15. The method of claim 1 further comprising the steps of:

loading a stop timer once a vehicle stop request signal has been received;

decrementing the stop time once the vehicle has come to a stop;

determining whether another vehicle stop request signal has been received; and

releasing the vehicle brake system if the stop time has expired and another vehicle stop request signal has not been received.

16. A method for stopping a vehicle comprising the steps of:

sending a signal requesting the vehicle to stop via an apparatus remote from the vehicle brake actuating device;

processing the signal within the vehicle antilock braking ECU;

sending a signal to the vehicle brake system to apply the brakes;

applying the vehicle brake system to stop the vehicle;

sending an engine torque reduction signal after a vehicle stop request signal has been received; and

reducing the vehicle engine torque.

17. The method of claim 16 further comprising the steps of

processing the vehicle stop request signal only upon receipt of a vehicle stop identifier request signal.

processing the vehicle stop request signal only upon receipt of a vehicle stop identifier request signal;

and

broadcasting a vehicle identifier signal when a vehicle stop identifier signal has been received.

18. The method of claim 16 further comprising the step of receiving the vehicle stop request signal with a receiver.

19. The method of claim 16, wherein said receiver is mounted on a vehicle trailer.

20. The method of claim 16 further comprising the step of communicating the vehicle stop request signal to the vehicle antilock braking ECU via an existing vehicle communication bus.

21. The method of claim 20, wherein said vehicle communication bus is the vehicle Power Line Carrier.

22. The method of claim 16, wherein the vehicle stop request signal is generated manually.

23. The method of claim 22, wherein the vehicle stop request signal is generated from within the vehicle cabin.

24. The method of claim 16 further comprising the step of encoding said vehicle stop request signal.

25. The method of claim 16 further comprising the steps of:

sending a brake release signal; and

releasing the vehicle brake system.

26. The method of claim 16 further comprising the step of applying the vehicle parking brakes once the vehicle has come to a stop.

27. The method of claim 16, wherein the vehicle is a commercial vehicle.

28. A method for stopping a vehicle comprising the steps of:

sending a signal requesting the vehicle to stop via an apparatus remote from the vehicle brake actuating device;

processing the signal within the vehicle antilock braking ECU;

sending a signal to the vehicle brake system to apply the brakes;

applying the vehicle brake system to stop the vehicle;

loading a stop timer once a vehicle stop request signal has been received;

decrementing the stop time once the vehicle has come to a stop;

determining whether another vehicle stop request signal has been received; and

releasing the vehicle brake system if the stop time has expired and another vehicle stop request signal has not been received.

29. The method of claim 28, wherein the vehicle is a commercial vehicle.

30. The method of claim 28, further comprising the step of encoding said vehicle stop request signal.

31. The method of claim 28, further comprising the steps of:

sending a brake release signal; and

releasing the vehicle brake system.

32. A vehicle stop mechanism comprising:

a means for receiving a signal from an apparatus remote from the vehicle brake actuating device requesting the vehicle to stop;

a means for processing the signal within a vehicle antilock braking ECU;

a vehicle brake system;

a means for sending a vehicle stop request signal to the vehicle brake system; and

a means for running diagnostic tests, wherein said diagnostic tests determine whether a vehicle stop request signal can be received.

33. A vehicle stop mechanism comprising:

a means for receiving a signal from an apparatus remote from the vehicle brake actuating device requesting the vehicle to stop;

a vehicle brake system;

a means for processing the signal within a vehicle antilock braking ECU and a means for sending said signal to said vehicle brake system;

a means for sending an engine torque reduction signal after a vehicle stop request signal has been received; and

a means for reducing the vehicle engine torque.

34. The vehicle stop mechanism of claim 33, wherein said a means for receiving a signal from an apparatus remote from the vehicle brake actuating device requesting the vehicle to stop is a receiver.

35. The vehicle stop mechanism of claim 34, wherein said receiver is located on a vehicle trailer.

36. The vehicle stop mechanism of claim 35, wherein said receiver is located in a secure location on the vehicle trailer.

37. The vehicle stop mechanism of claim 33, further comprising a means for encoding said vehicle stop request signal.
