Assembling for sensing a frontal impact in a vehicle

摘要

A system for sensing a head-on collision in a vehicle is proposed, where at least one upfront sensor is used as plausibility sensor, which provides a plausibility signal for a collision sensor located in the control device. The upfront sensor is an acceleration sensor, which analyzes both the acceleration signal as well as the speed signal derived therefrom for a plausibility check. The results of this check are linked in an OR-operation in order to generate a plausibility signal. In a refinement, it is provided to buffer-store the plausibility signal in the control device for a predetermined time. This is of special interest for improved reliability in the event that the upfront sensor has been destroyed.
