Release device for passenger restraint systems in a motor vehicle
First Claim
1. A device for triggering an occupant protection system in a vehicle for protection of vehicle occupants in a collision, comprising:
- a vehicle acceleration detector;
means for generating a delay signal as a function of vehicle acceleration determined by said vehicle acceleration determined by said vehicle acceleration detector;
a triggering control device which having a triggering threshold, for triggering at least said occupant protection system in response to said delay signal exceeding said triggering threshold; and
a collision parameter detection unit which includes;
an object detection unit which can detect a collision object in an area near the vehicle, and can determine at least a relative speed between the collision object and the vehicle;
a signal generator which can be controlled by the object detection unit and which, whenever a collision object is detected, specifies a collision parameter signal that depends on determined relative speed; and
means for adjusting the triggering threshold of the triggering control device as a function of said collision parameter signal.

Abstract
The invention relates to a triggering control device for occupant restraint systems in a vehicle whose triggering readiness can be influenced as a function of collision-relevant parameters. According to the invention, collision parameter detection comprises object detection, which can detect a collision object before a collision occurs in an area near the vehicle, and can determine at least a relative speed. Whenever a collision object is detected, a signal generator delivers a collision parameter signal that depends on the relative speed determined. In a preferred embodiment the collision parameter detection unit also determines the intrinsic speed of the vehicle and whenever no collision object is detected, the signal generator supplies a collision parameter signal influenced by the intrinsic speed.
