Abstract
A vehicle includes a motor generator, and a heater core for adjusting a temperature in a vehicle compartment by using operating oil supplied to the motor generator. The heater core includes a tube in a first region that connects between an inlet portion and an outlet portion, a tube in a second region that connects between the inlet portion and the outlet portion, and a first adjusting valve for shutting off, where a temperature of the operating oil is lower than a prescribed temperature range, flow of the operating oil in the tube in the second region by being changed to a closed position, and for adjusting an amount of flow of the operating oil in the tube in the second region in accordance with the temperature of the operating oil where the temperature of the operating oil is within the prescribed temperature range.
