A motor vehicle air conditioner control system that maintains a target cooling vent temperature without sacrificing vehicle engine performance. When a vehicle air conditioning compressor increases to above a predetermined speed and the vehicle engine driving force increases, such as during a period of engine acceleration, compressor cooling capacity becomes saturated and does not increase. When the speed of the compressor rises to a predetermined value and the compressor assumes a high-speed state, thereafter, while the compressor is in the high-speed state, operation of the compressor is controlled so as to sustain the vent-air temperature of an evaporator determined at a time when the high-speed state has been assumed. As a result, the amount of increase of the driving force due to this compressor speed increase is suppressed by reducing the volume of the compressor, thereby resulting in power savings while securing substantially maximum cooling capacity.
