摘要

A process for the plausibility check of a sensor signal of at least an environment sensor of a passive and / or active safety system of a vehicle by– from the sensor signal of the impact velocity at the point in time of a collision with a collision object is determined predictively,– for the determination of the course of the structural rigidity of the vehicle starting with the time of the collision as a function of a by means of a time integral of the predictively certain impact velocity certain deformation path a acceleration-based collision load is calculated,– the values of the calculated collision load with a threshold values are stored in the safety system in the case of a reference collision with a rigid wall occurring collision load are compared, and– the value of the predictively certain impact velocity as plausible is detected if the values of the calculated collision load oxygen correspond to at most the threshold values.
