UTILIZATION OF VEHICLE PORTAL STATES TO ASSESS INTERIOR COMFORT AND ADJUST VEHICLE OPERATION TO PROVIDE ADDITIONAL FUEL ECONOMY
First Claim
1. A method for a plug-in hybrid-electric vehicle, comprising:
- during a first engine-running condition, where a vehicle window or vent is in a more closed position, operating a climate control system to provide a user-requested level of thermal comfort; and
during a second engine-running condition, where the vehicle window or vent is in a less closed position, limiting a performance of the climate control system.

Abstract
A method of operating a heating, ventilation and air-conditioning system of a plug-in hybrid electric vehicle, comprising during a first engine-running condition, where a vehicle window or vent is in a more closed position, operating a climate control system to provide a user requested level of thermal comfort, and during a second engine-running condition, wherein the vehicle window or vent is in a less closed position, limiting the performance of the climate control system and biasing shared vehicle resources to provide additional fuel economy. In this manner, thermal comfort of the vehicle passengers can be maintained while providing additional fuel economy.

15. A vehicle system, comprising:
-
an engine; a heating, ventilation, and air-conditioning system; a plurality of vehicle windows and/or vents; and a computer-readable medium having code therein, the computer-readable medium comprising; code for operating a heating, ventilation and air-conditioning system of a vehicle during a first engine-running condition, where a vehicle window or vent is in a closed position, to provide a user requested level of thermal comfort; code for operating the heating, ventilation, an air-conditioning system during a second engine-running condition, wherein the vehicle window or vent is in an open position, and having an open vehicle window or vent state greater than a threshold open criteria, limiting a performance of the heating, ventilation, an air-conditioning system and biasing shared vehicle resources to provide additional fuel economy. - View Dependent Claims (16, 17, 18, 19)

20. A method for a plug-in hybrid-electric vehicle, comprising:
during; engine-running conditions with a window closed, maintaining a user-requested thermal comfort level via a climate control system; engine-running conditions with the window open and fogging unlikely, maintaining less than the user-requested thermal comfort level via a first, larger, climate control system performance reduction; and engine-running conditions with the window open and fogging likely, maintaining less than the user-requested thermal comfort level via a second, smaller, climate control system performance reduction.
