DEVICE AND METHOD FOR GENERATING AN ACTIVATION CRITERION FOR AN IMPACT PROTECTION SYSTEM OF A VEHICLE

摘要

The invention relates to a device for generating an activation criterion for an impact protection system of a vehicle provided with an impact sensor unit (2) comprising a vehicle outer skin part (2.1), which can change its position relative to a vehicle chassis due to a force acting upon the vehicle outer skin part (2.1), and comprising at least two sensors (2.2), which are provided for detecting a force acting upon the vehicle outer skin part and which each furnish at least one sensor output signal (2.3). The inventive device is also provided with a processing unit (3) for evaluating the at least two sensor output signals (2.3). The processing unit (2.3) carries out a classification of a collision object based on the temporal course of the sensor output signals (2.3) and, according thereto, generates an activation criterion (6) for the impact protection system. The classification of the collision object improves the making of a decision to generate an activation criterion and thus prevents erroneous activations of the impact protection system that can potentially cause additional injuries.
