SYSTEM AND METHOD FOR ENVIRONMENTAL MANAGEMENT OF A VEHICLE
First Claim
1. A system for environmental management of a vehicle, comprising:
- a heating, ventilating and air conditioning (HVAC) system;
at least one manual override for controlling a respective function of the HVAC system; and
a controller configured to control the HVAC system to automatically effect defogging based on at least one measured input when the at least one manual override is not selected, and to prohibit defogging when at least one manual override of the at least one manual override is selected.

Abstract
A system and method for environmental management of a vehicle automatically operates a vehicle climate control system to quickly and efficiently defog a vehicle windshield, while still operating at or near environmental comfort guidelines determined by a vehicle occupant. The method may be executed by an HVAC control system that is configured with a preprogrammed algorithm to operate an HVAC to achieve the desired results. A number of sensors can provide inputs to the control system, which can also receive inputs from a number of manual overrides operable by an occupant of the vehicle. The preprogrammed algorithm is configured to act on the various inputs to operate the HVAC to strike an appropriate balance between occupant comfort and windshield defogging.
