Zusammenfassung:In a vehicle with a first operating mode in which all vehicle wheels have substantially no lateral movement on a road surface and a second operating mode in which at least some of the vehicle wheels have lateral movement on the road surface, and with an actuator capable of affecting vehicle yaw rate, a vehicle yaw rate control method comprising the steps of: measuring an actual vehicle yaw rate; measuring vehicle steering wheel position; in the second mode of operation, determining a desired yaw rate command linearly responsive to the measured steering wheel position; wherein the actuator is controlled to minimize a difference between the measured vehicle yaw rate and the desired vehicle yaw rate.
