Abstract

A method controls functions in a vehicle having at least one wheel-speed sensor (15) and having one or more signal generators and/or signal receivers assigned, in particular, to a vehicle rear. In accordance with the method, a direction of rotation is also detected with the wheel-speed sensor (15). In addition, the signal generators and/or signal receivers are actuated automatically in a manner depending on signals of the wheel-speed sensor (15).

Claims

1. A method for controlling functions in a vehicle having a wheel-speed sensor (15) and having at least one of signal generators or signal receivers assigned to a vehicle rear, the method comprising the steps of

detecting a direction of rotation with the wheel-speed sensor (15), and

actuating the at least one of the signal generators or signal receivers automatically in a manner depending on signals of the wheel-speed sensor (15).

2. The method as claimed in claim 1, wherein an active ABS sensor is used as the wheel-speed sensor (15).

3. The method as claimed in claim 1 wherein the at least one of the signal generators or signal receivers operates with optical or acoustical signals.

4. The method as claimed in claim 1 further comprising the step of controlling a braking operation of the vehicle based on signals of the signal receivers.

5. The method as claimed in claim 1, wherein the vehicle has a lift axle forming the signal receiver, wherein the lift axle is actuated automatically in a manner depending on the signals of the wheel-speed sensor (15).

6. The method as claimed in claim 5, wherein the lift axle is relieved or raised when reverse travel is detected by the wheel-speed sensor (15).

18. A vehicle with a system as claimed in claim 6, wherein the vehicle is a trailer (10).

19. The method as claimed in claim 3, wherein the at least one of the signal generators or signal receivers is at least one of a reversing lamp (19), a reversing camera, a distance sensor, or another element of a rear-space monitoring system.

7. A system for controlling functions in a vehicle having at least one wheel-speed sensor (15) and having one at least one of signal generators or signal receivers assigned to a vehicle rear, wherein the system is configured to detect a direction of rotation with the wheel-speed sensor (15), and for driving the at least one of the signal receivers or signal generators in a manner depending on signals of the wheel-speed sensor (15).

8. The system as claimed in claim 7, further comprising a control unit (17) that also controls an electronic braking system of the vehicle.

9. The system as claimed in claim 7, wherein the wheel-speed sensor (15) has been assigned to an electronic braking system.

10. The system as claimed in claim 7 wherein the wheel-speed sensor (15) is an active ABS sensor.

11. The system as claimed in claim 7 wherein the at least one of the signal receivers or signal generators operates with optical or acoustical signals.

12. The system of claim 7, wherein the vehicle has a lift axle, the system being configured to detect a direction of rotation with the wheel-speed sensor (15), and for driving the lift axle in a manner depending on the signals of the wheel-speed sensor (15).

13. The system as claimed in claim 12, wherein the system is configured to relive or raise the lift axle when the vehicle is reversing.

14. The system as claimed in claim 12, further comprising a control unit (17) that also controls an electronic braking system of the vehicle.

15. The system as claimed in claim 12 wherein the wheel-speed sensor (15) has been assigned to an electronic braking system.

16. The system as claimed in claim 12 wherein the wheel-speed sensor (15) is an active ABS sensor.

20. The method as claimed in claim 11, wherein the at least one of the signal generators or signal receivers is at least one of a reversing lamp (19), a reversing camera, a distance sensor, or another element of a rear-space monitoring system.
