ABSTRACT:
In a power assisted vehicle steering system, an actual traveling direction of the vehicle, and a tangential direction of a road on which the vehicle is traveling are detected, and the actuator for the steering system is controlled so as to reduce or minimize a deviation of the actual traveling direction of the vehicle from the road tangential direction. Thus, a supplemental steering torque is produced so as to force the direction of the vehicle into agreement with the direction of the road so that the effort required for the vehicle operator to maintain the vehicle on the road can be reduced or even eliminated, and the lateral stability of the vehicle is improved both on straight roads and curved roads.
