摘要:
A car defogging system reduces energy required to defog a windshield glass of the car. A temperature sensor mounted at the windshield glass detects the glass surface temperature, Ts. A humidity sensor spaced from the windshield glass by a predetermined distance detects the humidity, H, around the windshield glass. A temperature sensor mounted inside the windshield glass detects peripheral temperature Te around the glass. A system controller determines if fog is or is not present by comparing the dew point temperature Td with the surface temperature Ts. Dew point temperature Td is derived by the combining values of H and a temperature Tc based on a combination of Ts and Te.
