  • Method and system for predicting air discharge temperature in a control system which controls an automotive HVAC system
    Patent number: 5937940
    Abstract: Method and system for predicting air discharge temperature in a control system which controls an automotive HVAC (heating, ventilation and air conditioning) system using a model. The model is based on signals generated by various climate control sensors and actuation outputs to predict air discharge temperature without the need for an additional sensor. The model allows the avoidance of uncomfortable air discharge temperatures to thereby increase passenger comfort.
