摘要：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 impactspeed. A measure of the impact speed is ascertained in that first the instant of the impactonset of the vehicle against an obstacle is detected and then the instant is detected whenthe acceleration of the rigid support structure of the vehicle transitions from light toheavy acceleration. The time difference between the impact-onset instant and theacceleration-transition instant is a measure of the impact speed. To ascertain the instants,integral values of acceleration signals from acceleration sensors may be utilized andanalyzed in an appropriate manner. The method and device are applicable, in particular, inthe discrimination of impact processes at low driving speeds.
