System for environmental management of a vehicle

摘要

A system and method for environmental management of a vehicle automatically operates a vehicle climate control system to 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.
