Vehicle fuel gauge calibration method and device, storage medium and electronic equipment

Abstract

The invention discloses a vehicle fuel gauge calibration method. The method comprises the steps: obtaining the resistance change maximum value of a fuel sensor when a vehicle is on a flat road and ona preset slope; when the vehicle is stopped and powered off, determining a first resistance value corresponding to the remaining fuel quantity of the vehicle; when the vehicle is started and powered on, obtaining a second resistance value actually measured by the fuel quantity sensor; judging the relationship between the absolute value of the difference value between the first resistance value andthe second resistance value and the resistance change maximum value: when the absolute value of the difference value is greater than the resistance change maximum value, controlling the vehicle fuelgauge to display the fuel quantity value corresponding to the second resistance value; when the absolute value of the difference value is smaller than or equal to the resistance change maximum value,controlling the vehicle fuel gauge to display a fuel quantity value corresponding to the first resistance value; according to the scheme, the adverse effect of the gradient on display of the fuel gauge during ramp parking is overcome; meanwhile, the situation that when an oil adding and leaking event exists in the oil tank, the oil gauge misjudges that the oil tank is stopped on a slope, and consequently the oil gauge displays mistakenly is avoided.

Description

technical field [0001] The present application relates to the technical field of vehicle instrumentation, in particular to a calibration method, device, storage medium and electronic equipment for a vehicle fuel gauge. Background technique [0002] When the vehicle is turned on and powered on, the fuel quantity displayed on the vehicle fuel gauge is obtained after conversion based on the resistance value measured by the fuel level sensor in the fuel tank to the remaining fuel quantity. However, when the vehicle is on a level road or a slope road, due to the change of the slope, the fuel tank will form a certain inclination angle, the oil level in the fuel tank will change accordingly, and the actual resistance value detected by the fuel sensor will also change with the slope, so the same The amount of remaining oil will cause differences in the amount of oil displayed on the oil gauge on different slopes. The problem that produces like this is: the person on board can't acc...
