Abstract
A vehicle air conditioner control system has an air conditioning device has a compressor, a condenser, an expansion valve, and an evaporator, a compressor running rate control device, a deceleration fuel cutoff executing device, and a fuel supply recovery executing device that cancels cutoff of fuel supply and recovers fuel supply at a higher vehicle speed during vehicle deceleration fuel cutoff period with air-conditioner ON than during vehicle deceleration fuel cutoff period with air-conditioner OFF. The compressor running rate control device increases the compressor running rate for a predetermined period just before a fuel supply recovery time with air-condition ON during the deceleration fuel cutoff period more than during non-execution of the deceleration fuel cutoff, and subsequently decreases the compressor running rate at or just before the fuel supply recovery time with air-condition ON equal to or less than during non-practice of the deceleration fuel cutoff.
