DRIVE August 29, 2024

An electrified vehicle includes a drive device including an alternating current motor and an inverter that drives the alternating current motor, a control device that controls the drive device, and a heat transfer device that transfers heat of the drive device to a heating target. When a predetermined heat requirement condition transferred to the heating target is satisfied, the control device executes loss increase control to control the drive device so that the power loss increases compared to a case where the heat requirement condition is not satisfied. When an index value regarding a rotation speed of the alternating current motor is less than a first threshold, the loss increase control includes first control to make a d-axis current of the alternating current motor larger than a reference d-axis current, which is the d-axis current when the heat requirement condition is not satisfied.
