ABSTRACT:
Method and system for modifying the control of an automotive HVAC (heating, ventilation and air conditioning) to prevent the formation of cabin temperature stratification. The control algorithm responds to signals generated by various climate control sensors to calculate a value representing the likelihood of stratification. The stratification strategy achieves the following three functions: (1) calculation of the likelihood of stratification, (2) estimation of probable level of stratification, and (3) modification of strategy to dispel stratification. Fuzzy logic calculations are performed based on fuzzy rules and membership functions to provide these functions and to allow the control to be expressed in simple heuristic terms.
