Abstract
A method of defogging an inner surface of a vehicle windshield glass. The method includes a first process of defogging by changing a heating, ventilation, and air-conditioning (HVAC) system from a heating mode to a cooling mode when fogging occurs on the inner surface of the vehicle windshield glass; once the inner surface of the vehicle windshield glass is changed to a defogging state by the first process, a second process of pre-defogging by turning off a compressor of the HVAC system for a predetermined period of time under a prescribed condition to prevent flash fogging; and after the second process, when the predetermined period of time elapses, a third process of turning on the compressor to return from the cooling mode to the heating mode.
