On a vehicle jolt attractive apparatus and method for actuation of a fahrzeuginsassenrueckhaltesystems in a passenger vehicle

摘要

Apparatus and method are provided for actuating a passenger restraint system in a passenger vehicle. Vehicle deceleration is sensed and a vehicle condition signal is provided which varies in value with that of vehicle deceleration. The condition signal is differentiated to provide a jerk signal having a value which varies with the rate of change of the vehicle deceleration. A predetermined time period is timed only so long as the value of the condition signal exceeds that of a first threshold level. A second signal is provided so long as the value of the jerk signal exceeds that of a jerk threshold level. A trigger signal is provided for actuating the restraint system only when the second signal occurs during the predetermined time period.
