ABSTRACT:
Method and system for modifying a linear control algorithm which controls an automotive HVAC (heating, ventilation and air conditioning) system using fuzzy logic. The control algorithm responds to signals generated by various climate control sensors to produce a desired vehicle air temperature as set by an operator of the vehicle. Fuzzy linear control achieves the following three functions: (1) calibration blending, (2) target set point adjustment, and (3) non-linear offset compensation. 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.
