Abstract: A control device includes a switching control unit, an information acquisition unit, and a difference acquisition unit. The switching control unit performs switching control that increases braking torque of the braking device while decreasing braking torque of the rotating electrical machine, when a vehicle is decelerated.

After the information acquisition unit detects the stopped state of the vehicle, the switching control unit corrects output torque of the rotating electrical machine based on the braking torque difference.

Abstract: A shift range control device switches a shift range by controlling driving of a motor. A learning unit learns, as a position correction value, a normal state time correction value calculated based on first and/or second reference angles when an output shaft signal is available when turning on of a start switch. The first reference angle is a motor angle when the output shaft signal changes in response to the rotation of the motor in a first direction. The second reference angle is the motor angle when the output shaft signal changes in response to the motor rotation in a second direction opposite to the first direction. A motor angle target value is set by using the normal state time correction value stored during a period from when all the output shaft signals are determined to be unavailable to when the start switch is turned off.
