Abstract
Many internal combustion engines have an auxiliary means for controlling airflow into the engine at idle, such as an Automatic Idle Speed (AIS) motor to compensate for changing load requirements. A method is disclosed for controlling the AIS motor and in turn engine idle speed to compensate for changing loads due to the operation of the air conditioner. The method recognizes the relationship between ambient temperature and pressures generated within the air conditioning compressor and the compensation necessary to maintain a smooth idle speed. The method also utilizes adaptive learning to relate a 'looked up' of the air conditioner to the current value of auxiliary air flow required by a warmed up engine.
