PROBLEM TO BE SOLVED: To provide a front and rear wheel steering angle controller for a vehicle which, even when a rear wheel steering angle reached the upper control limit, can stably control the behavior of the vehicle without giving uncomfortable feeling to the driver by providing a front wheel auxiliary steering angle imparting means and a rear wheel auxiliary steering angle imparting means. SOLUTION: In the steering angle controller for a vehicle, the front and rear wheel auxiliary steering angle control means has a saturation judgment part which makes a judgment on whether or not the rear wheel auxiliary steering angle is close to the saturation upper limit value. When the result of the judgment is that the rear wheel auxiliary steering angle is close to the saturation, a target front wheel steering angle is computed based on a first target lateral speed and the maximum rear wheel steering angle value. The generating yaw rate generated by the computed target front wheel steering angle and the maximum rear wheel steering angle value is computed, and the front wheel auxiliary steering angle is computed using the computed generating yaw rate as a second target yaw rate.
