1. A method of predicting a rollover of a vehicle, the method comprising:

  • determining a vehicle roll angle indicative of a direction of roll;

    determining whether a vehicle impact event has occurred;

    selecting a first threshold value based on the roll angle and selecting a second threshold value that is based on motion of the vehicle in the direction of roll;

    comparing a first signal indicative of motion of the vehicle to the first threshold value; and

    comparing a second signal indicative of kinetic energy of the vehicle to a second threshold value;

    wherein a vehicle rollover is predicted when a vehicle impact has not occurred and the first and second signals exceed the first and second threshold values, respectively.
