Abstract
A target value for yaw angle velocity gain is computed according to a map expressing a relationship between steering wheel angle and yaw angle velocity gain predetermined such that a direction as seen from a driver of a target destination point for vehicle travel at a predetermined time after a forward gaze and a direction as seen from the driver are caused to match each other, and a steering gear ratio is controlled accordingly. A target value for a steering wheel torque corresponding to the detected steering wheel angle and the acquired yaw angular velocity is set, based on a relationship between yaw angular velocity and resistance-feel level predetermined such that the resistance feel level for a driver monotonically increases with increasing yaw angular velocity. Control is then preformed so as to realize the steering wheel torque target value.
