Abstract
In a cooling path of a motor, an oil control valve is provided between a motor cooling oil path and a first motor cooling path, a first heat exchanger is provided in the first motor cooling path, and a second heat exchanger is provided in a second motor cooling path. In a motor-drive mode, a valve control unit switches the oil control valve to the first motor cooling path side when an engine temperature is lower than a first threshold, and switches the oil control valve to the second motor cooling path side when the engine temperature is equal to or higher than the first threshold. In the first heat exchanger, motor cooling oil and engine oil exchange heat. In the second heat exchanger, the motor cooling oil and a coolant for the engine exchange heat.
