Abstract
In a powered vehicle steering system which produces a steering reaction for controlling the lateral movement of the vehicle, the steering reaction including a yaw rate reaction component and a steering wheel damping component, when the vehicle operator is firmly holding the steering wheel or actually turning the steering wheel, the damping component is reduced so that the effort required for turning the steering wheel may be reduced, and the vehicle operator may turn the steering wheel without any substantial effort. Conversely, if the vehicle operator is not firmly holding the steering wheel, and the steering wheel is allowed to move freely, the damping component is increased so that the lateral movement of the vehicle may be stabilized even when the vehicle is subjected to disturbances such as crosswind. Thus, the stability of the lateral movement of the vehicle and the responsiveness of the vehicle steering system can be ensured at the same time.
