Abstract
A system for controlling a fan in a vehicle comprises an ambient temperature module that generates an ambient temperature enable signal when ambient temperature is within a vaporization window. An engine component monitoring module that generates a vaporization temperature enable signal when an engine component in an engine compartment has an estimated outer surface temperature that greater than a water vaporization temperature. A vehicle speed module generates a speed enable signal when the vehicle speed is less than a first vehicle speed. A fan turn-on module that selectively turns on a fan based on the temperature enable signal, the vaporization temperature enable signal and the speed enable signal.
