Abstract
A vehicle air conditioner control system has an air conditioning device for performing a refrigerating cycle, having a compressor that intakes, compresses, and discharges a refrigerant, a condenser that condenses the refrigerant discharged from the compressor, an expansion valve that depressurizes the refrigerant condensed by the condenser, an evaporator that performs heat exchange between open air and the refrigerant to vaporize the refrigerant, a compressor ON/OFF control device that controls a running rate of the compressor by alternating between an ON state and an OFF state, a vehicle deceleration fuel cut-off executing device that performs cut-off fuel supply during vehicle deceleration, and a fuel supply recovery executing device that cancels fuel cut-off and recovers fuel supply during vehicle deceleration fuel cut-off period based on a demand to turn on the compressor.
