Abstract
An automobile moves at a traveling speed in accordance with the position of an acceleration pedal. A compressor is driven by the engine of the automobile. The discharge displacement of the compressor is adjusted by an external control procedure. When the position of the acceleration pedal reaches a determining value, or above at which it is determined that engine power is needed for accelerating the vehicle, the compressor is controlled such that the discharge displacement decreases. The determining value is selected by a controller in relation to the traveling speed detected by a speed sensor. The determining value increases as the speed increases.
