    摘要: The present invention is directed to controlling a vehicle multistage actuatable occupant restraining system (14, 18). A crash sensor (32, 36) senses crash acceleration and provides a crash acceleration signal (110, 160) indicative thereof. Crash velocity and crash displacement are determined (118, 168) in response to the crash acceleration signal. A first stage (90, 94) of the multistage actuatable occupant restraining system is actuated when the determined crash velocity as a function of crash displacement exceeds a low threshold (130, 132, 180, 182). A crush zone accelerometer (40, 42) senses crash acceleration at a crush zone location. The crush zone acceleration as a function of the crash displacement is compared (226, 256) against a crush zone threshold (220, 222, 250, 252). The value of the low threshold (130, 180) is switched to a different value (132, 182) when the crush zone acceleration exceeds the crush zone threshold.

    摘要: An apparatus for controlling an actuatable occupant restraint device of a vehicle comprises a central crash accelerometer that senses crash acceleration at a vehicle location and that provides a first crash acceleration signal indicative thereof. A side pressure sensor senses pressure in a chamber disposed at a side of the vehicle and provides a side pressure signal indicative thereof. A controller actuates the actuatable occupant restraint device in response to the first crash acceleration signal and the side pressure signal. The controller determines a first moving average of acceleration value comprising a moving average of acceleration in a direction generally perpendicular to a longitudinal axis of the vehicle determined from the first crash acceleration signal. The controller determines a change in pressure value comprising a change in pressure in the chamber determined from the side pressure signal. The controller actuates the actuatable occupant restraint device when both the first moving average of acceleration value exceeds a first threshold and the change in pressure value exceeds a second threshold.
