Patent number: 6776435Abstract: 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.Type: GrantFiled: April 9, 2001Date of Patent: August 17, 2004Assignee: TRW Inc.Inventors: Chek-Peng Foo, Paul Leo Sumner, Timothy Chester Wright, Meng-Fu Tsai, Suthep Thanapathomsinchai
