ABSTRACT:
An electronic crash sensor which can operate appropriately in response to any form of crash of a vehicle. An input acceleration waveform from an accelerometer is first processed to peak cut any portion thereof lower than a predetermined value. Then, a value obtained such peak cutting is time integrated. Then, a time integrated value of a predetermined function is subtracted from a value obtained by such time integration. Then, the value of the acceleration waveform thus obtained is compared with a predetermined time function value, and when the former is higher than the latter, a triggering signal is delivered to a trigger circuit to trigger operation of a passenger protecting apparatus such as an air bag of the vehicle.
