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.
