Automatic Demisting Control of Automobile Windshield Glass

This paper describes the development of the control device for automatic demisting. The control is started from the mist possibility(MP) = 0, which is defined as the temperature difference between dew point and glass surface temperature. The control strategy for automatic demisting was installed in FATC unit and successfully demonstrated by the vehicle test in cold and hot chamber, ranging from 0° to 30°C.
