1. A method for a plug-in hybrid-electric vehicle, comprising:
- during a first engine-running condition, including when 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, wherein the more closed position comprises the vehicle window or vent being open;
less than a threshold opening amount, orbeing open less than a threshold time; and
during a second engine-running condition, including when the vehicle window or vent is in a less closed position, limiting a performance of the climate control system relative to the performance of the climate control system during the first engine-running condition, wherein the less closed position comprises the vehicle window or vent being open greater than the threshold opening amount for greater than the threshold time.

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 method, comprising,
during engine operation: -
operating an air conditioner compressor via engine output, the compressor operated at a requested level when a window is open less than a threshold amount or a threshold time; and operating the air conditioner compressor at a reduced level below the requested level when the window is open more than the threshold amount for longer than the threshold time. - View Dependent Claims (16)
