Abstract

A method and apparatus for controlling an automobile air conditioner wherein a deviation between the actual in-car temperature and a desired in-car temperature is periodically calculated to detect such various thermal disturbances as changes of the solar heat, the temperature of outside air, the number of passengers and the like, and wherein a compensation value of the opening angle of the air-blend door is determined in accordance with the periodical variation of the deviation to ensure stable control of the in-car temperature.
