Abstract
An electronic control unit is configured to generate a pulse width modulation signal of a plurality of switching elements based on a modulation factor and a voltage phase of a voltage based on a torque command of a motor and a pulse number per unit cycle of an electric angle of the motor and perform switching of the switching elements. The electronic control unit is configured to generate the pulse width modulation signal of the switching elements such that total loss of the motor and an inverter when a heat conversion request of drive electric power of the motor has been issued becomes greater than the total loss when the heat conversion request has not been issued.
