1. A yaw stability control system for a vehicle comprising:

  • at least one vehicle status sensor generating at least one sensor signal;

    at least one driver input sensor generating at least one input signal;

    a yaw rate sensor generating a yaw gradient signal that reflects a yaw rate difference between sequential sampling instants;

    a lateral acceleration sensor generating a lateral acceleration signal;

    a controller disabling normal yaw stability control operation associated with tire force differentials and enabling a body-force-disturbance yaw stability control operation, comprising at least partially reducing normal yaw stability control response functions associated with the at least one input signal and performing body-force-disturbance yaw stability control functions in response to the at least one sensor signal; and

    the controller incrementally increasing brake pressure greater than that applied by normal yaw stability control operation in response to the yaw gradient signal and the lateral acceleration signal.
