Abstract
In an electric control method for an automobile air conditioner, a digital computer is utilized to calculate a function required to direct the actual in-car temperature toward a desired value in consideration with various changes of ambient temperature and the calculation is compensated to effectively reduce a difference between the actual in-car temperature and the desired value when the rate of change of the actual in-car temperature becomes below a predetermined value.
