Restraint system with impact recognition, taking into account environmental influences
First Claim
1. A safety device for a vehicle that can be activated upon an impact of the vehicle against an obstacle, comprising:
- a first sensor arrangement for acquiring the vehicle impact and for outputting a first sensor signal;
a control device for outputting a triggering signal dependent on the first sensor signal;
a restraint system that is triggered dependent on the first sensor signal for a protection of a vehicle occupant during the vehicle impact;
a second sensor arrangement for acquiring the obstacle in a vicinity of the vehicle and for outputting a second sensor signal; and
a third sensor arrangement for acquiring an environmental influence on the second sensor arrangement and for outputting a third sensor signal dependent on the environmental influence;
wherein the control device determines, based on the second sensor signal, whether to trigger the restraint system after an evaluation of the third sensor signal.

Abstract
A safety device for vehicles having first sensor arrangement for acquiring the vehicle impact and for outputting first sensor signals, a control device for outputting triggering signals dependent on the first sensor signals, and a restraint system that is triggered dependent on the first sensor signals, second sensor arrangement being provided for the acquisition of obstacles in the vicinity of the vehicle and for the outputting of second sensor signals, and third sensor arrangement being provided for the acquisition of environmental influences on the second sensor arrangement, the second sensor signals output by the second sensor arrangement being used in the control unit for the decision concerning the triggering of the restraint system, after an evaluation of the third sensor signals output by the third sensor arrangement.

10. A method for activating a safety device for a vehicle upon an impact of the vehicle against an obstacle, comprising:
-
acquiring a first sensing variable by a first sensor arrangement for recognizing the vehicle impact against the obstacle; outputting a first sensor signal via the first sensor arrangement; determining by a control device a triggering signal dependent on the first sensor signal; triggering a restraint system dependent on the first sensor signal for protecting a vehicle occupant during the vehicle impact against the obstacle; acquiring a second sensing variable by a second sensor arrangement for recognizing the vehicle impact against the obstacle; outputting a second sensor signal from the second sensor arrangement; acquiring a third sensing variable by a third sensor arrangement for recognizing an environmental influence on the second sensor arrangement; outputting a third sensor signal from the third sensor arrangement dependent on the environmental influence; and causing the control device to determine, based on the second sensor signal, whether a triggering of the restraint system is to occur after an evaluation of the third sensor signal. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23)
