  • Method and apparatus for controlling an actuatable restraint device using crash severity indexing
    Patent number: 6036225
    Abstract: 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).
