摘要

An air-conditioning method and system for an automotive vehicle according to the present invention automatically maintains the temperature of air within the passenger compartment at a value preset by a passenger compartment air temperature presetting device and adjusted to a comfortable temperature which varies according to the outside-air temperature in accordance with a predetermined relationship defined by three linear functions having two points of intersection. The method comprises the steps of calculating a basic outlet duct air temperature, calculating an outlet duct air temperature correction, adding the two calculated values, and calculating an air mix door opening percentage, in addition to calculating a comfortable passenger compartment air temperature.
