PROBLEM TO BE SOLVED: To provide a steering angle control device for vehicle to perform a yaw rate feedback control of the steering angle within the range not going beyond the gripping limit of tire. SOLUTION: A steering angle control device for a vehicle is equipped with an auxiliary steering angle adjusting mechanism 14 installed in a transmission path of a steering angle transmitting mechanism and made adjustable for the steering angle of a steering wheel 10, an actuator 19 to drive the auxiliary steering angle adjusting mechanism, and a controlling means (controller 20) to control the actuator through yaw rate feedback control, wherein the controlling means is furnished with a presuming means to presume the limit value of cornering force and corrects the yaw rate feedback of the target steering angle so that the target figure of cornering force corresponding to the target steering angle does not exceed the limit value of cornering force. |
