1. A limited yaw rate control method in which vehicle wheels are differentially braked in response to a yaw command based on a deviation of a vehicle yaw rate from a desired yaw rate, the improvement comprising the steps of:

  • measuring a lateral acceleration of the vehicle;

    developing a preliminary yaw rate limit based on the measured lateral acceleration;

    forming a first stage yaw rate limit according to the lesser in magnitude of the desired yaw rate and the preliminary yaw rate limit, while preserving the polarity of the desired yaw rate;

    forming a second stage yaw rate limit according to a peak excursion of the first stage yaw rate limit; and

    limiting the desired yaw rate according to the lesser in magnitude of the second stage yaw rate limit and the desired yaw rate.
