Claim One:
1. A device for detecting side impact in a vehicle, comprising: at least one pressure sensor system in at least one side part of the vehicle, wherein the at least one pressure sensor system is configured to produce a signal; at least one evaluation circuit configured to recognize a side impact as a function of the signal from the at least one pressure sensor system; at least one test device configured to test an operability of the at least one pressure sensor system, wherein the at least one test device is configured to over-sample the signal from the at least one pressure sensor system and then filter the over-sampled signal in order to produce a test signal, and wherein the at least one test device is further configured to compare the test signal to a predefined reference value and determine the operability of the at least one pressure sensor system based on the comparison; wherein the over-sampling and filtering of the signal is sufficient to achieve a high resolution.
