  • Fuel level gauge control systems and methods
    Patent number: 8869610
    Abstract: A system includes a fuel level determination module, an adjusting module, and a gauge control module. The fuel level determination module outputs a measured fuel level based on a fuel level signal generated by a fuel level sensor. After an ignition system of the vehicle is turned on, the adjusting module adjusts a present fuel level toward the measured fuel level based on a first rate when a refueling event was detected while the ignition system was off and adjusts the present fuel level toward the measured fuel level based on a second rate when a refueling event was not detected while the ignition system was off. The first rate is faster than the second rate. The gauge control module controls a fuel level gauge to display the present fuel level.
