Abstract

A control device and a method for triggering passenger protection arrangement for a vehicle are described, in which the triggering occurs as a function of at least one signal from a rear crash sensor system monitoring a rear region of the vehicle. The triggering of the passive passenger protection arrangement takes place as a function of at least one threshold comparison of the at least one signal.

Claims

1-10. -10. (canceled)

11. A method for triggering a passenger protection arrangement for a vehicle, the method comprising:

providing at least one signal from a surround sensor system monitoring a rear region of the vehicle;

performing at least one threshold comparison of the at least one signal; and

triggering the passenger protection arrangement as a function of the at least one signal from the surround sensor system monitoring the rear region of the vehicle, wherein the triggering of passive passenger protection means occurs as a function of the at least one threshold comparison of the at least one signal.

12. The method of claim 11, wherein at least one trigger threshold is influenced as a function of the at least one signal.

13. The method of claim 11, wherein the triggering is suppressed when one of the at least one signal and a derivation of the at least one signal lies below a minimum threshold.

14. The method of claim 11, wherein the threshold comparison is used for a plausibility check.

15. The method of claim 14, wherein at least one threshold of the threshold comparison is modified as a function of the comparison.

16. The method of claim 13, wherein at least one of an influencing of the at least one trigger threshold and a modification of the at least one threshold is implemented as a function of the at least one signal for a specified period of time and then canceled again.

17. The method of claim 11, wherein an object type is used as the at least one signal.

18. The method of claim 13, wherein the at least one signal is compared to the minimum threshold after a specified period of time.

19. The method of claim 11, wherein the triggering is suppressed as a function of the driving direction.

20. A control device for triggering a passenger protection arrangement for a vehicle, comprising:

an interface arrangement to provide at least one signal of a surround sensor system monitoring a rear region of the vehicle; and

an evaluation arrangement to induce a trigger arrangement to trigger the passenger protection arrangement as a function of the at least one signal;

wherein the evaluation arrangement includes a threshold comparator for the at least one signal, and further includes an output arrangement to transmit an implementation signal to the trigger arrangement as a function of an output signal of the threshold comparator, so that the trigger arrangement triggers the passive passenger protection arrangement.
