Abstract
A device for controlling the steering angle of a vehicle over a wide range maintaining improved control precision. The device controls the steering angle &thgr;d through a steering drive device,so as to come in agreement with a target angle &thgr;,. A steering angle detection device includes a first potentiometer,that produces a first angle detection value &thgr;,and a second potentiometer,that produces a second angle detection value &thgr;,. A target torque operation means,includes an angle operation unit,for operating the steering angle based on the first and second angle detection values, and the angle operation unit,produces the first angle detection value as the steering angle outside the second angular range, and produces the second angle detection value as the steering angle inside the second angular range.
