Patent number: 8160804Abstract: A system and method for controlling an internal combustion engine of a vehicle during an automatic shutdown process, in particular to cool the engine to a predetermined safe shutdown temperature, includes the steps of determining that vehicle-idle conditions exist and whether an engine-associated temperature exceeds a predetermined first threshold temperature value, for which a cooling fan is operated to cool the engine, or higher second threshold temperature, for which at least one of the cooling fan and a coolant pump is operated above idle levels and the engine speed may be increased above idle to cool the engine. Cooling fan and/or coolant pump operation is reduced when the engine temperature is determined to have decreased to below the first threshold temperature value.
