An electronic control unit is configured to perform pulse width modulation control. The pulse width modulation control is to generate signals of a plurality of switching devices of an inverter by comparing a modulation wave of a voltage command of each phase based on a torque command of the motor, with a carrier wave, and perform switching of the switching devices. The electronic control unit is configured to generate the carrier wave so that, in each unit interval, a required time in the unit interval is equal to a total time of a plurality of unit components, and, in at least one unit interval, durations of at least two unit components of a plurality of unit components are different from each other.
