Abstract
An improved vehicle climate control system develops a fog factor indicative of the relative potential of windglass fogging, and uses the index to schedule offsets to normal control settings of the system. The air dewpoint temperature at the front windglass is estimated based on relative humidity and a reference temperature, and the fog factor is determined as a function of the estimated air dewpoint temperature and a measure of the windglass temperature. The fog factor is used to offset an air inlet door, mode doors, refrigerant compressor capacity, discharge air temperature, and blower motor speed.
