摘要： An apparatus (10) for controlling a multistage actuatable occupant restraining system (14, 18) of a vehicle includes a crash sensor (32) sensing crash acceleration at a substantially central location of the vehicle. A crush zone accelerometer (40, 42) is provides a crush zone crash acceleration signal. A controller (50) a crash velocity value and a crash displacement value in response to the crash acceleration signal. A plurality a predetermined crash velocity as a function of crash displacement threshold maps (152-172) is provided, two of the plurality of threshold maps (170, 172) relating to a second stage (92, 96) of said multistage actuatable occupant restraining system. The selects one of the two threshold maps relating to the second stage of in response to the crush zone acceleration signal and controls second stage actuation in response to a comparison of the crash velocity signal against the selected one of the two threshold maps (170, 172). Improved misuse margins are also provided as well as deployment mappings based on symmetric and asymmetric crash detection.
