Abstract

In a method for evaluating the output signal (a) from a sensor (1), an average value (M) is formulated from a plurality of successively measured values (ai) of the output signal (a). Subsequently, the difference (D) between this measured value (M) and one succeeding measured value of the output signal (a) from the sensor (1) is determined, and finally the thus formulated differential value is compared to a specified threshold value to derive a criterion for activating a restraining device for protecting motor vehicle occupants.
