1. In a motor vehicle, a system for triggering a safety device comprising:

  • a sensor mounted in said vehicle for generating an analog signal representative of instantaneous vehicle acceleration (deceleration);

    means for converting said analog signal to digital acceleration data;

    means for transforming said acceleration data to a signal space vector; and

    signal space discriminator means responsive to said signal space vector for triggering the safety device when a value calculated from said signal space vector exceeds a threshold value therefor.
