Abstract
An ECU includes a plurality of control circuits which is configured to control driving of a motor and communicate each other. The control circuits are configured to switch control modes including an ADS mode for controlling the driving of the motor based on a steering angle command θs* and a torque control mode for controlling the driving of the motor based on a torque command value. A first control circuit, which calculates an EPS current command value shared by the plurality of control circuits in an EPS mode, and a second control circuit, which calculates an ADS current command value shared by the plurality of control units in an ADS mode, are different. This makes it possible to reduce a calculation load as compared with a case where the same control circuit serves as an EPS master and an ADS master.
