Abstract

A device for triggering restraining means in a vehicle in which the vehicle velocity is taken into consideration in the triggering. In the process, the vehicle velocity is checked for plausibility by the signal from a remote sensor so as to avoid faulty triggering.

Claims

1-8. -8. (canceled)

9. A device for triggering a restraining device in a vehicle, comprising:

an arrangement for triggering the restraining device as a function of a velocity of the vehicle, the arrangement considering the vehicle velocity as a function of a signal from at least one remote sensor.

10. The device according to claim 9, wherein the sensor is an acceleration sensor.

11. The device according to claim 9, further comprising means for modifying at least one threshold to which at least one crash signal is compared for the triggering of the restraining device, as a function of the vehicle velocity.

12. The device according to claim 11, further comprising means for subdividing the vehicle velocity into a predefined class as a function of a magnitude of the vehicle velocity and then for modifying the threshold as a function of the class.

13. The device according to claim 9, wherein the at least one remote sensor is an upfront sensor.

14. The device according to claim 13, further comprising means for comparing the signal of the upfront sensor to a plausibility threshold, the plausibility threshold lying below a trigger threshold for generating a crash signal of the upfront sensor, the vehicle velocity being taken into consideration in the triggering of the restraining device as a function of the comparison.

15. The device according to claim 11, wherein the vehicle velocity leads to a modification of the threshold in a frontal algorithm.

16. The device according to claim 11, wherein the vehicle velocity leads to a modification of the threshold in an upfront algorithm.
