Abstract: An assist control unit calculates an assist torque command based on a steering torque. A steering angle control unit calculates a steering angle control torque command so that a steering angle determined according to an output of a motor follows a target steering angle commanded from a lane keeping support device. A vibration application control unit calculates a lane departure warning control torque command to apply vibration to an assist torque when a lane departure warning activation request is notified. A motor drive control unit controls a drive of the motor based on an addition value of the assist torque command, the steering angle control torque command, and the lane departure warning control torque command. The steering angle control unit includes a vibration removal filter configured to remove vibration frequency components of the lane departure warning device in calculations on a steering angle signal loop for steering angle control.
