Abstract

In device for side impact recognition in a vehicle, at least one pressure sensor system that produces a signal is provided in a side part of the vehicle, and an evaluation circuit is provided that recognizes a side impact as a function of the signal. In addition, a test device is provided for the at least one pressure sensor system, the at least one test device being configured such that the at least one test device oversamples the signal and then filters it in order to produce a test signal, the test device comparing the signal with a reference value and, as a function of this comparison, recognizing the operability of the at least one pressure sensor system.
