Abstract
A system for controlling steering of a vehicle, including an electric motor used for power-steering torque assist control. The system has an navigation system whose output is used to correct the detected steering angle input by the vehicle driver. A desired yaw rate is determined based on the corrected steering angle and the detected vehicle speed using a yaw rate model, thereby enabling to conduct the aforesaid lane-keeping-steering torque assist control in a more appropriate manner. Further, if the vehicle driver expresses a positive intention to steer the vehicle by himself, for example, so as to avoid an obstacle present on the road, the control is discontinue to meet the wishes of the vehicle driver. Furthermore, the system monitors the steering of the vehicle driver to prevent the vehicle driver from relying upon this steering assist control to an excessive extent.
