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.
