ABSTRACT:
A method and device for controlling the triggering of passive safety systems, such as airbags in vehicles, in response to criteria being detected that are to be interpreted as the existence of a dangerous impact. One of these criteria is the impact speed. A measure of the impact speed is ascertained in that first the instant of the impact onset of the vehicle against an obstacle is detected and then the instant is detected when the acceleration of the rigid support structure of the vehicle transitions from light to heavy acceleration. The time difference between the impact-onset instant and the acceleration-transition instant is a measure of the impact speed. To ascertain the instants, integral values of acceleration signals from acceleration sensors may be utilized and analyzed in an appropriate manner. The method and device are applicable, in particular, in the discrimination of impact processes at low driving speeds.
