ABSTRACT:
The refrigerant compressor of a motor vehicle air conditioning system in which the compressor is normally cycled on and off according to cooling demand is maintained continuously on or continuously off during idle operation according to a measure of the compressor duty cycle. During non-idle operation, a measure of the compressor duty cycle is compared to a reference duty cycle corresponding to a cooling demand above which it is desired to maintain the compressor on during idle operation and below which it is desired to maintain the compressor off during idle operation. At the onset of idle operation, the compressor is maintained on or off, and at the expiration of a time period corresponding to the duration of idle operation typically encountered in stop and go driving, normal compressor cycling is resumed.
