In a safety system and a method of operating a sensor in a safety system, the sensor transmits an electric reaction signal to a central system unit, and is also excited by the central system unit by a diagnostic and/or excitation signal as a reversible electro-mechanical system.

Method for operating a sensor in a safety system

In a method for controlling a safety system in a vehicle, wherein an output signal of at least one impact sensor is subjected to frequency analysis in an evaluation unit which is integrated into an electronic control unit, the frequency analysis is performed in at least one predetermined frequency range, the spectrum of the output signal is compared with references patterns, the dependence of the spectrum on the present speed of the vehicle and/or the present outside temperature of the vehicle is taken into account, and a triggering signal is generated from the control unit to trigger planned protective measures if a person to be protected is detected with at least a predetermined probability.
