1. An impact event countermeasure control method for an automotive vehicle, comprising the steps of:

  • sensing deceleration of the vehicle during an impact event;

    setting a countermeasure deployment timer in the event that said sensed deceleration exceeds a first threshold;

    integrating said sensed deceleration to calculate the time-based displacement of an occupant within said vehicle;

    comparing the calculated displacement of said occupant with a displacement threshold at the time said countermeasure deployment timer expires; and

    in the event that said calculated displacement is less than said displacement threshold when said countermeasure expires, delaying deployment of a countermeasure until said displacement threshold is crossed.
