Abstract
A vehicle climate control system develops a fog index based on relative humidity at or near the inner surface of the windshield, and uses the fog index to variably override the normal control settings. The relative humidity is combined with a pair of humidity thresholds to form a dimensionless fog index, and fog index values within a predetermined range are applied to a variable path function for transitioning between existing control settings and control settings that maximize defogging.
