ABSTRACT:
A drive component for driving an electric water pump for causing engine coolant to flow is mounted in an engine compartment. When the ignition is off and the temperature of a exhaust heat recovery device is above a temperature, an ECU estimates a peak temperature in the engine compartment after the stop of the engine. When the peak temperature is above a temperature, the ECU stops the engine and drives the electric water pump and an electric fan for cooling the drive component for driving the electric water pump.
