Abstract
A method for checking a sensor signal suitable for actuating a passenger protection arrangement of a vehicle. The method includes a step of carrying out a comparison between the sensor signal and at least one reference signal, repeatedly within a predetermined time interval, in order to obtain a plurality of comparison results, and a step of evaluating the sensor signal based on the plurality of comparison results, in order to detect a fault in the sensor signal.
