Abstract:
In an electric vehicle, an automatic transmission is provided between a differential unit and drive wheels. The differential unit includes a motor-generator and a power split device, and the motor-generator is cooled by lubricant of the automatic transmission. A battery charger is operable to charge a power storage device using a power supply outside the vehicle. When the temperature of the lubricant is lower than a predetermined temperature upon execution of charging of the power storage device using the charger, and the automatic transmission is in a neutral state, or a power cutting-off state, the controller rotates the motor-generator of the differential unit so as to perform warming control for raising the temperature of the lubricant.
