ABSTRACT:
An apparatus for controlling actuation of an occupant restraint system in a vehicle includes an accelerometer for providing a signal having a characteristic indicative of a vehicle crash condition. A microcomputer monitors the output of the accelerometer at a plurality of different times and determines an instantaneous power value from the plurality of monitored acceleration signals. The microcomputer further determines a vehicle delta velocity value from the acceleration signal. The microcomputer compares the instantaneous power and the delta velocity against associated thresholds. The microcomputer actuates the occupant restraining device when the vehicle delta velocity value exceeds its threshold within a time period from when the instantaneous power value exceeds its threshold.
