A motor controller has an assist controller that generates an assist instruction AC to generate an assist torque for lightening a steering load based on a detected value of a steering torque, and a follow controller obtaining a target value of a physical quantity regarding a steering operation and generating a follow instruction TC of a follow control. Further, an intervention detector in the motor controller detects an intervention of a driver or of a system, and a restrictor restricts an internal value that is used by the assist controller or by the follow controller, so that a ratio of the assist torque against the automatic steering torque is changed, which makes it possible to switch a control to the driver or to a system without a causing a wrong feeling to the driver.
