1. A method of detecting an impending soil trip rollover event of a vehicle, comprising the steps of:

  • determining a roll rate and a lateral acceleration of the vehicle;

    sampling the determined lateral acceleration and buffering a plurality of sampled values to create a first lateral acceleration profile;

    establishing a second lateral acceleration profile characteristic of a plow phase of a soil trip rollover event;

    cross-correlating said first and second lateral acceleration profiles and identifying a first peak correlation value;

    establishing a correlation threshold that decreases with increasing values of the determined roll rate; and

    detecting the impending rollover event when said first peak correlation value crosses said correlation threshold.
