1. An air bag deployment system for use in a vehicle, the control system comprising:

  • sensing means for sensing vehicle deceleration due to a collision, said sensing means generating a deceleration signal; and

    a processor operatively connected to said sensing means and receiving the deceleration signal, said processor including;

    means for calculating the velocity and signal energy from said deceleration signal, wherein said signal energy is determined by accumulating the absolute difference of successive deceleration signal values taken to a predetermined power greater than two,means for comparing said velocity and signal energy to predefined discrete velocity and energy thresholds, respectively, andmeans for generating a deployment signal when both of said velocity and signal energy exceed their respective thresholds.
