Abstract
A controlled compressor apparatus for idle-stopping vehicles that permits precise variable displacement control of a compressor and reduces power consumption when the compressor is motor-driven. The apparatus includes a battery-powered motor and a control unit for selecting the engine or the motor to drive the compressor and for controlling the displacement of the compressor. A current detector detects the magnitude of a current supplied to the motor. The control unit stores a relationship between the displacement and the current and controls the displacement based on the current detected by the current detector.
