ABSTRACT:
A system for controlling a safety device for a vehicle includes first and second switching elements connected to a power source in serial relation to the safety device. The control system further includes a pair of acceleration sensors, a pair of analog processing circuits, and a microcomputer. In accordance with an deceleration signal from the corresponding acceleration sensor, each analog processing circuit outputs a collision decision signal. In accordance with the signals from the acceleration sensors, the microcomputer makes calculations to output two collision decision signals respectively from two output ports thereof. The control system further includes two logic elements. One of the logic elements, when simultaneously receiving any two out of the above four collision decision signals, turns on one of the two switching elements. The other logic element, when simultaneously receiving the other two collision decision signals, turns on the other switching element. When both of the two switching elements are turned on, the safety device is operated.
