Abstract:
A method of operation for an automatic climate controller that develops HVAC climate control commands for regulating an air temperature in a cabin of a motor vehicle in accordance with an occupant set temperature, comprising the steps of:tabulating nominal HVAC climate control command profiles as a function of a Power Index generally corresponding to ambient temperature; tabulating an HVAC power requirement vs. Power Index function based on the nominal HVAC climate control profiles and the set temperature; and in vehicle operation: computing an HVAC power requirement for regulating the cabin air temperature; retrieving a Power Index corresponding to the computed HVAC power requirement using the tabulated HVAC power requirement vs. Power Index function; and retrieving HVAC climate control commands based on the retrieved Power Index using the tabulated nominal HVAC climate control command profiles.
