1. An apparatus for determining a vehicle rollover, comprising:

  • at least one inertial sensor for detecting a potential vehicle rollover;

    a plurality of tire sensors; and

    an arrangement that uses signals from the plurality of tire sensors to determine a plausibility of the detection of the potential vehicle rolloverwherein the plausibility determination includes;

    measuring a tire pressure for each tire on the vehicle;

    calculating a first value by multiplying the pressure measurements for each tire on a first side of the vehicle by each other;

    calculating a second value by multiplying the pressure measurements for each tire on a second side of the vehicle by each other;

    calculating a ratio of the first value to the second value; and

    determining the plausibility based at least in part on the ratio.
