ABSTRACT:
Acceleration sensors in a vehicular safety system with at least two acceleration sensors are stimulated by an electrical or sound excitation so that one of the sensors functions as a body sound transmitter, while the other(s) receive(s) these signals and vice versa. The performance which includes a calibration check, and the coupling to the housing structure are evaluated through a signal processing circuit. The safety system including its output trigger stage, remains switched-on during testing.
