  • Patent number: 8155833
    Abstract: The present invention relates to a method for controlling the operation of a compressor for preventing noise that occurs in case of the shortage of refrigerant flow caused by less discharge capacity of the compressor of an air conditioner for a vehicle. The compressor includes a cylinder bore for compressing a refrigerant, a piston inserted into the cylinder bore, a swash plate having a controllable slope with respect to a drive shaft, and a control valve for controlling the slope of the swash plate. The discharge capacity of the compressor is increased if it is determined that vehicle speed and accelerating rate satisfy predetermined conditions. If a low flow rate state of refrigerant of the compressor is predicted, the ECV duty is increased to prevent the compressor from entering the low flow rate state, thereby improving the workability of the compressor and solving the noise problem.

  • Patent number: 7214911
    Abstract: 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.

  • Publication number: 20060289458
    Abstract: An automotive vehicle defogging system prevents dissipation of energy required to defog the automotive vehicle wind shield. A surface temperature sensor mounted on the wind shield detects the glass surface temperature. A humidity sensor spaced from the wind shield glass by a predetermined distance detects the humidity around the wind shield. A peripheral temperature sensor mounted inside from the wind shield glass detects peripheral temperature around the glass. Dew point temperature is obtained in response to the detected humidity H and a temperature value based on the temperatures detected by the surface and peripheral temperature sensors. The presence of fog is detected by comparing the dew point temperature with the surface temperature Ts.
