ABSTRACT:
A SIR system has frontal air bags and side air bags both controlled by the same microprocessor. To guard against spurious deployment of side air bags with minimal software burden, a lateral accelerometer and an arming circuit detect side crash activity and apply an arming signal to a pulse accumulator circuit in the microprocessor which monitors the accumulator state to detect arming, thereby inhibiting deployment when the arming signal is absent. The arming circuit receives the accelerometer signal, removes the dc component which is subject to drift, adds a fixed offset voltage and compares the resultant signal to threshold values to produce an arming signal when a threshold is breached.
