1. A method for estimating a cornering limit of an automotive vehicle, comprising:

  • sensing vehicle operating conditions and a vehicular yaw rate;

    detecting a lateral acceleration of the vehicle and determining whether the lateral acceleration is equal to zero;

    calculating vehicle parameters and a yaw rate reference value;

    calculating a yaw rate error on a basis of the yaw rate reference value and a previously sensed vehicular yaw rate;

    estimating whether the vehicle operating conditions, the vehicle parameters and the yaw rate error are within a predetermined range of given thresholds, responsive to a driving situation of a condition if the lateral acceleration is determined as being unequal to zero;

    triggering a driver warning if the vehicle operating conditions, the vehicle parameters and the yaw rate error are within a predetermined range of the thresholds; and

    controlling the vehicle operating conditions so that the vehicle operating conditions, the vehicle parameters and the yaw rate error are within the predetermined range of the thresholds.
