Abstract
Method and control system for controlling an automotive HVAC (heating, ventilation and air conditioning) system to prevent the discharge of air within a predetermined temperature range. The control system responds to signals generated by various climate control sensors to prevent the HVAC system from producing air at an uncomfortable range of temperatures. Fuzzy logic calculations are performed based on fuzzy rules and membership functions to provide nonlinear compensation and to allow the control to be expressed in the same heuristic terms that an occupant could use in describing the level of comfort.
