1. An apparatus for controlling actuation of a passenger restraint system in a vehicle, said apparatus comprising:

  • sensing means for providing a time domain vibratory electric signal having frequency components indicative of a vehicle crash condition;

    means for transforming the time domain vibratory electric signal over at least two time intervals into associated frequency domain signals;

    means for summing at least one frequency component of one frequency domain signal with at least one frequency component of the other frequency domain signal;

    means for actuating the passenger restraint system when the summation of said at least one frequency components of the frequency domain signals indicates a predetermined type of vehicle crash is occurring.
