1. A method for estimating a propensity of a vehicle to rollover, the method comprising the steps of:

  • determining lateral kinetic energy of said vehicle in response to vehicle longitudinal velocity and vehicle side slip angle;

    measuring a lateral acceleration of said vehicle; and

    determining a rollover potentiality index in response to said lateral kinetic energy and said lateral acceleration.
