<p>PROBLEM TO BE SOLVED: To reduce electric power consumption in a vehicle configured to cool a motor drive device by using a vehicle air conditioner.SOLUTION: A vehicle includes: a motor generator; a PCU driving the motor generator by using electric power from a power storage device; and a cooling device 200. The cooling device 200 includes: a first circulation path for air-conditioning in the vehicle; a second circulation path for cooling the PCU; a water-cooled heat exchanger exchanging heat between the first and second circulation paths; a compressor installed in the first circulation path; and an electric pump 260 installed in the second circulation path. When the motor generator performs regenerative operation, an ECU 300 drives the compressor by using surplus electric power that cannot be stored in the power storage device out of regenerative electric power generated by the regenerative operation, and when the compressor can be driven at a higher load compared to the case where the regenerative operation is not performed by using the surplus electric power, the ECU 300 reduces rotating speed of the electric pump 260.</p> |
