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.

Vehicle cooling controller and cooling control method

An engine start control apparatus, includes a code storing device which stores a plurality of normal codes which indicate a normal vehicle key belonging to a vehicle and a key corresponding to the normal vehicle key, and an immobilizer which determines as to whether an inherent code input form one of a signal input device and an inherent code input device is included in the normal codes stored in the code storing device, and on the basis of the results of determination, the immobilizer controls permitting/prohibiting the starting of the engine. Therefore, when the normal code of the plurality of normal codes and the input inherent code match, the immobilizer permits the starting of the engine.
