  • Patent number: 11913393
    Abstract: A vehicle fuel system includes a turbocharger having a compressor disposed on an intake line of an engine. The compressor selectively compresses intake air supplied to the engine. The fuel system has a canister configured to capture fuel vapor discharged from a fuel tank and a purge control valve configured to open or close the purge line depending on a pressure of the intake line. The fuel system has a check valve provided on the purge line that blocks movement of a fluid from the intake line to the canister. The fuel system has a controller performing control such that the purge control valve is operated in a closed mode to prevent intake air in the intake line from being introduced into the fuel tank when breakdown of the check valve is sensed during driving of the vehicle.

  • Publication number: 20230419881
    Abstract: A display device of the disclosure includes a grayscale converter which converts input grayscales into output grayscales based on a scale factor, a data driver which converts the output grayscales into data voltages, a plurality of pixels which receives the data voltages and displays an image based on the data voltages, and a current sensor which provides a sensing current by sensing a first power current supplied to the plurality of pixels to display the image. When a load corresponding to the input grayscales is greater than a minimum load, the grayscale converter adjusts a change amount of the scale factor based on a current difference between a target current corresponding to the load and the sensing current.
