Abstract

A device for controlling restraining means takes a signal characterizing the trailer into consideration in controlling the restraining means.

Claims

1-9. -9. (canceled)

10. A device for controlling a restraining device in a vehicle having a trailer, the device comprising:

an arrangement for controlling the restraining device as a function of at least one signal of the trailer.

11. The device according to claim 10, wherein the at least one signal indicates a presence of the trailer.

12. The device according to claim 11, further comprising an electrical trailer coupling and a circuit coupled to the electrical trailer coupling, the circuit generating the at least one signal.

13. The device according to claim 10, wherein the at least one signal indicates a weight of the trailer.

14. The device according to claim 10, wherein the at least one signal indicates a load distribution of the trailer.

15. The device according to claim 10, wherein the at least one signal indicates a movement of the trailer.

16. The device according to claim 10, wherein the at least one signal is transmitted via a signal transmission from the trailer to the vehicle.

17. The device according to claim 14, further comprising a weight sensor system situated in the trailer for generating the at least one signal.

18. The device According to claim 15, further comprising a vehicle dynamics sensor system situated in the trailer for generating the at least one signal.

19. The device according to claim 15, further comprising a friction sensor system situated on a coupling head for generating the at least one signal, wherein the friction sensor system, with the aid of friction elements on a coupling jaw, detects movements of the trailer.
