Abstract
A system for controlling air bag deployment in vehicles includes the capability of accommodating varying inductants values in the air bag circuit. Wire harnesses that couple air bag components have varying characteristics, such as length, which affect the inductants value of the circuit. The inventive arrangement utilizes charge and discharge times of at least one capacitor for measuring the inductants of a particular circuit. The system includes a controller that accommodates the inductants by introducing an appropriate delay in the firing circuit signal to operate the air bag.
