Vaporization reduction control system and method for a vehicle
First Claim
1. A system for controlling a radiator fan in a vehicle comprising:
- an ambient temperature module that generates an ambient temperature enable signal when ambient temperature is within a vaporization temperature range;
an engine component monitoring module that generates a vaporization temperature enable signal when;
a coolant temperature is greater than a first temperature and less than a second temperature, andan air-conditioning pressure is greater than a first pressure and less than a second pressure; and
a fan turn-on module that turns on the radiator fan;
when at least one of (i) the coolant temperature is greater than the second temperature and (ii) the air-conditioning pressure is greater than the second pressure; and
when (i) the ambient temperature enable signal and (ii) the vaporization temperature enable signal are generated.

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.
