Embodiment Construction
[0034] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail with reference to the accompanying drawings.
[0035] Such as figure 1 As shown, an automotive fuel tank calibration system provided by an embodiment of the present invention includes a fuel tank 1, a measuring cup 2, a water reservoir 3, and a pressure sensor 5. The water reservoir 3 is used to deliver calibration to the fuel tank 1 and the measuring cup 2. Liquid; multiple pressure sensors 5, the probes of which are respectively set at the bottom of the measuring cup 2 and the fuel tank 1; the water storage cup 3 transports the calibration liquid to the fuel tank 1 and the measuring cup 2 respectively, and the pressure sensor 5 is used to record the fuel tank 1 and the measuring cup 2 When the two hydraulic pressures are the same, the height of the calibration liquid in the fuel tank 1 is equal to the ...

The invention discloses a vehicle fuel tank calibration system and method. The vehicle fuel tank calibration system includes a fuel tank, a measuring cup, a water storage cup and a pressure sensor, and the water storage cup is used to deliver calibration liquid to the fuel tank and the measuring cup; A pressure sensor, the probes of which are respectively set at the bottom of the water storage cup and the fuel tank; At the same time, the height of the calibration liquid in the fuel tank is equal to the height of the calibration liquid in the measuring cup. The vehicle fuel tank calibration system and method provided by the present invention compare the hydraulic pressure in the fuel tank with the hydraulic pressure in the measuring cup, and obtain the liquid height in the fuel tank from the scale value of the measuring cup according to the relationship between the pressure and the liquid height, thus The continuous height value of the fuel tank can be obtained from the continuous scale value on the measuring cup, thereby improving the accuracy of fuel tank calibration and correspondingly improving the accuracy of the fuel gauge.
Description
Technical field [0001] The invention relates to automobile technology, in particular to a system and method for calibrating an automobile fuel tank. Background technique [0002] During the use of the vehicle, the driver needs to estimate the mileage of the vehicle based on the amount of fuel displayed on the fuel gauge. In the design of the whole vehicle, the shape of the fuel tank of the automobile matches the shape of other parts of the body. Therefore, the fuel tank is often designed to be irregular, which makes it more difficult to obtain the amount of fuel in the fuel tank and more difficult to accurately calibrate. Fuel gauge. [0003] The calibration process of the fuel gauge in the prior art is to first measure the total volume of the fuel tank, and then fill the fuel tank with a quarter of the total volume of calibration liquid each time after the entire vehicle is assembled. The fuel gauge is checked to make it display accurately, and thus the fuel gauge has obtained m...
