A method for controlling cycling of an air conditioning compressor coupled
to an internal combustion engine interrupts normal cycling based on
operation conditions. In addition, normal engaged and disengaged cycling
durations are adaptively estimated in real-time. The method of the present
invention achieves improved fuel economy and improved drive feel. As an
example, improved fuel economy is achieved by engaging the compressor
during braking or when the engine is being driven by the vehicle. As
another example, improved drive feel is achieved by engaging the
compressor during transient conditions when drive feel is unaffected.
