Abstract
Method and control system for economically controlling an automotive HVAC (heating, ventilation and air conditioning) system using fuzzy logic. The control system responds to signals generated by various climate control sensors including a humidity sensor to produce a desired vehicle air temperature and air flow. Fuzzy logic calculations are performed based on fuzzy rules and membership functions to provide nonlinear compensation for setting the rate of clutch cycling in a CCOT system or refrigerant metering in a TXV system.
