Date Sep. 19, 1991.An accelerometer arrangement includes an accelerometer for producing a signal representative of the acceleration or deceleration of a vehicle and processing circuitry for processing the signal from the accelerometer by either integrating or differentiating to produce a processed signal, comparing the processed signal with at least one reference signal, and providing an output signal when the reference signal is exceeded by the processed signal. At least one of the reference signal and the processing of the signal vary in a predetermined manner with time. |
