Method for verification of accident events in automobiles

摘要

The method involves providing an ultrasonic sensor (2) for activating an irreversible support unit, and performing detection of a possible impact before accident events and impact recognition by the ultrasonic sensor. Signals of a precrash detection are processed by an evaluation unit for determining a release time point for the support unit. An activation of the support unit is determined by the evaluation unit based on an impact speed and impact time point to be estimated.
