A shift range switchover control ECU controls a motor of an actuator provided to switch over a shift range of a vehicle and includes a temperature estimation part and a driving control part. The temperature estimation part estimates a temperature of the motor 11 based on a driving state of the motor. The driving control part controls driving of the motor and limits the driving of the motor when an estimated temperature exceeds a protection temperature. The temperature estimation part calculates, based on a final temperature indicating the estimated temperature of a system stop time, a restart-time temperature, which is the estimated temperature at time of turning on a starting switch of the vehicle again after turning off the starting switch, and a delay period, during which the temperature estimation part continues to calculate the estimated temperature after turning off of the starting switch. It is thus possible to properly estimate the temperature of the motor.
