    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 side actuatable restraint (14, 16) includes a side acceleration sensor (22, 34) mounted to a vehicle at a side location and having an axis of sensitivity (24, 36) oriented in a direction substantially perpendicular to a front-to-rear axis (25) of the vehicle. The side sensor provides a discriminating crash signal when a transverse crash acceleration of the vehicle is sensed indicating a deployment crash event. A first central safing acceleration sensor (52) is mounted at a substantially central location of the vehicle (11) and having an axis of sensitivity (58) oriented in a direction substantially perpendicular to the front-to-rear axis (25) of the vehicle. The first safing sensor provides a first safing crash signal when a deployment crash acceleration is sensed in the transverse direction. A second central safing acceleration sensor (50) is mounted at the substantially central location of the vehicle (11) and having an axis of sensitivity (56) oriented in a direction substantially parallel to the front-to-rear axis (25) of the vehicle (11). The second safing sensor provides a second safing crash signal when crash acceleration is sensed in said first direction. An actuatable restraint is actuated when the side crash sensor (22, 34) provides the discriminating crash signal indicating a deployment crash event and when either said first (52) or said second (50) crash sensor provides a safing crash signal indicating a deployment crash event.
