Abstract: A target steering angle determining section determines a target steering angle based on the operation amount of the steering gear. A target angle setting section sets a target angle of a steered wheel. A control state switching section switches between an enabled state in which steering control is performed to deflect the steered wheel such that an actual steering angle reaches the target angle and a disabled state in which the steering control is not performed. When the steering control state is switched to the enabled state, the target angle setting section sets the target angle to an angle that was brought closer to the actual steering angle from the target steering angle. After the steering control state is switched to the enabled state, the target angle setting section brings the target angle closer to the target steering angle as time passes.
