    摘要: An apparatus and method for controlling an actuatable occupant restraint device having a plurality of actuatable stages (24, 26), the apparatus including a crash sensor (14, 16) for sensing crash acceleration and providing a crash acceleration signal indicative thereof. A controller (22) determines a velocity value (74) and a displacement value (80) from the crash acceleration signal. A safing function controls enabling and disabling of a deployment control circuit in response to the determined velocity (74) and displacement (80) values. A displacement based velocity threshold (133) and a displacement threshold value (125) define an immunity box. The velocity threshold value (133) varies as a step function of displacement. If the velocity/displacement values are within the immunity box, the safing function is in a disabling condition. If either value is outside of the immunity box, the safing function is in an enabling condition. A side impact sensor (28) and side impact crash event circuit (122) determine if a side impact crash event is occurring. If a side impact crash event is occurring, the threshold values (125, 133) of the immunity box are adjusted.

    摘要: An apparatus for controlling an actuatable occupant restraint device for a vehicle, the restraining device having a plurality of actuatable stages (24, 26), the apparatus including a crash sensor (14, 16) for sensing crash acceleration and providing a crash acceleration signal indicative thereof. A controller (22) includes an integrator (72, 172) for determining a velocity value from the crash acceleration signal and for providing a velocity signal (74, 174). The controller (22) is coupled to the actuatable device for (i) effecting actuation of a first of the actuatable stages (24) when the determined velocity value exceeds a first threshold value, and (ii) upon the determined velocity value exceeding a second threshold value, determining a crash severity index (112, 212) having a value related to a time interval from when the determined velocity value (74, 174) exceeds the first threshold value (88, 188) to when the determined velocity value exceeds the second threshold value (96, 196). The controller effects actuation of a second of the actuatable stages (26) in response to the crash severity index value (112, 212).

    摘要: A system (10) for controlling an actuatable occupant protection device (44, 46, 52, 48, 50, 54) includes an actuatable headrest device (44, 48) which, when actuated, helps protect an occupant of a vehicle seat (42, 43). A crash sensor (22) is operative to sense a condition of a vehicle (20) and provide a crash sensor signal having an electrical characteristic indicative of the sensed vehicle condition. A controller (24) is coupled to the actuatable headrest device (44, 48) and the crash sensor (22). The controller (24) determines a crash velocity value and a crash displacement value based on the crash sensor signal. The controller (24) has a threshold value functionally related to the determined crash displacement value. The controller (24) controls actuation of the actuatable headrest device (44, 48) in response to the determined crash velocity value relative to the threshold value.
