ABSTRACT:
An automotive air conditioner controller for controlling the operation of an automotive air conditioner employing a variable displacement compressor capable of gradually or continuously varying its displacement. While the engine of the automobile is idling, the automotive air conditioner controller adjusts the displacement of the compressor to or near to the maximum, varies desired idling speed of the engine according to required cooling ability, and adjusts the actual idling speed of the engine to the desired idling speed. Thus, the engine operates at an improved fuel consumption rate without reducing the cooling ability of the automotive air conditioner.
