Abstract

Apparatus comprising a control member for a valve for controlling a vehicle brake function, and an electrically operable lockout for the control member. An electronic reader associated with the lockout is operable in response to communication with a personal data device to control operation of the lockout. The reader may be used to effect credential verification of a vehicle driver and enable other functions.

Claims

1. Apparatus comprising:

a control member for a park control valve for controlling a vehicle parking brake;

an electrically operable lockout for the control member; and

an electronic reader associated with the lockout, the reader being operable in response to communication with a personal data device to control operation of the lockout.

2. Apparatus as set forth in claim 1 further comprising a personal data device operable to communicate with the reader to control operation of the lockout.

3. Apparatus as set forth in claim 1 wherein the personal data device is personalized to a driver of the vehicle.

4. Apparatus as set forth in claim 1 wherein the personal data device is an I-button brand device.

5. Apparatus as set forth in claim 1 wherein the personal data device is operable for controlling vehicle-related access functions.

6. Apparatus as set forth in claim 1 wherein the personal data device is operable to control vehicle functions other than access functions, such as logging driver activities.

7. Apparatus as set forth in claim 1 wherein the personal data device is operable to carry diagnostic information to and from the vehicle and the reader is operable to carry diagnostic information to and from the personal data device.

8. Apparatus as set forth in claim 1 wherein the personal data device is operable to carry software upgrades to the vehicle.

9. A method including the steps of:

providing a park control valve control member with an associated electrically operable lockout;

providing a reader that is electrically connected with the lockout;

positioning a transponder adjacent to the reader; and

disabling the lockout in response to said positioning step.

10. A method as set forth in claim 9 wherein said step of positioning a transponder near the reader comprises establishing wireless communication between the transponder and the reader.

11. A method as set forth in claim 9 wherein said step of positioning a transponder near the reader comprises making a direct mechanical connection between the transponder and the reader to establish electrical communication between the transponder and the reader.

12. Apparatus comprising:

a vehicle access control mechanism for use on a vehicle;

a reader that is electrically connected with the vehicle access control mechanism; and

a personal data device electrically cooperable with the reader to control operation of the vehicle access control mechanism;

the personal data device also being operable to control access to a device other than the vehicle.

13. Apparatus as set forth in claim 12 wherein the personal data device is also operable to control access to a doorway.

14. Apparatus as set forth in claim 12 wherein the personal data device is operable to carry diagnostic information to and from the vehicle and the reader is operable to cooperate with the personal data device to send diagnostic information to the personal data device and to receive diagnostic information from the personal data device.

15. Apparatus comprising:

a control member for a park control valve for controlling a vehicle parking brake;

an electrically operable lockout for the control member; and

means associated with the lockout for controlling operation of the lockout.

16. Apparatus as set forth in claim 15 wherein the means for controlling operation of the lockout comprises an electronic reader associated with the lockout, the reader being operable in response to communication with a personal data device to control operation of the lockout.

17. Apparatus as set forth in claim 16 further comprising a personal data device operable to communicate with the reader to control operation of the lockout.

18. Apparatus as set forth in claim 16 wherein the personal data device is personalized to a driver of the vehicle.

19. Apparatus as set forth in claim 16 wherein the personal data device is an I-button brand device.

20. Apparatus as set forth in claim 16 wherein the personal data device is operable for controlling vehicle-related access functions.

21. Apparatus as set forth in claim 16 wherein the personal data device is operable to control vehicle functions other than access functions, such as logging driver activities.

22. Apparatus as set forth in claim 17 wherein the personal data device is operable to carry diagnostic information to and from the vehicle and the reader is operable to carry diagnostic information to and from the personal data device.

23. Apparatus as set forth in claim 16 wherein the personal data device is operable to carry software upgrades to the vehicle.

24. An electropneumatic vehicle brake system including:

a pneumatic valve for controlling a vehicle brake function;

an electrically operable control member for controlling the valve;

an electronic control unit for operating the control member and thereby to control the valve;

a personal data device reader associated with the ECU; and

a personal data device that can be carried by a driver of the vehicle;

the ECU and reader being operable, in response to communication between the reader and the personal data device, to perform credential verification on the personal data device and, upon verification, enable operation of the control member thereby to enable control of the valve.

25. A system as set forth in claim 24 wherein the valve is a park brake valve, the ECU is operable to lock out the control member of the park brake valve, and the credential verification enables unlocking of the control member by the ECU.

26. A system as set forth in claim 25 wherein the system includes a park control solenoid valve module and wherein the ECU is operable to disable the solenoid drivers corresponding to the park release function of the module.

27. A system as set forth in claim 25 including means for providing an audible or visual notification of attempted park release when verified with a first sound and an audible notification of attempted park release when not verified with a second sound.

28. A system as set forth in claim 24 wherein the brake system is part of an electronic network of the vehicle including other nodes and the ECU is operable to transmit the credential verification to other nodes of the vehicle network.

29. A system as set forth in claim 28 wherein the credential verification enables reading and storing of fault information, and writing or firmware upgrades to the ECU.

30. A system as set forth in claim 24 wherein the pneumatic valve is a park control valve for controlling a vehicle park brake function, and the ECU and reader are operable to enable or disable operation of the control member thereby to enable controlling the park control valve by preventing sufficient pressure from being sustained at the supply inlet or the control inlet or the delivery outlet of the park control valve.
