The control device includes a target-value calculation unit calculating a target-value of a controlled variable that is torque of a rotating electrical machine, drive force, or acceleration of a vehicle, based on redundant signal and non-redundant signals, an inverter operation unit operating the inverter to control the controlled variable to the target-value, and a monitoring-value calculation unit calculating a target-monitoring-value of the controlled variable based on the redundant signal. A difference calculation unit that, when the vehicle travels forward, calculates a difference between the target-value and the target-monitoring-value when the target-value is a first determination value or more, and does not calculate the difference when the target-value is less than the first determination value, and that, when the vehicle travels rearward, calculates the difference when the target-value is a second determination value or less, and does not calculate the difference when the target-value is more than the second determination value.
