Abstract

The invention discloses a method for judging slope parking and refueling of an automobile fuel system. The automobile is equipped with an electronic stability system; the fuel system includes a fuel pump, an angle sensor, and a combination instrument. Get the current tilt angle of the vehicle; if the tilt angle is within the set range, it is considered to be on flat ground, and the instrument cluster displays the fuel amount in normal mode; if the tilt angle exceeds the set range, it is considered to be on a ramp, and it is displayed according to the ramp logic fuel volume. The above technical solution is used to judge the state of the vehicle body through the existing slope signal, so as to distinguish the slope parking state and the refueling state, improve the accuracy and timeliness of the fuel gauge indication, and realize the method of accurately judging the slope parking and refueling at low cost.

Description

technical field [0001] The invention belongs to the technical field of automobile fuel gauge display. More specifically, the present invention relates to a method for judging slope parking and refueling of an automobile fuel system. Background technique [0002] The indication principle of the fuel gauge is that the meter reads the resistance value of the fuel pump and displays the amount of fuel according to the relationship between the resistance value and the number of liters. In order to ensure the timeliness of fuel indication, the oil pump float usually has extremely low damping, and a slight fluctuation of the fuel level can change the height of the float and thus change the fuel resistance. [0003] Due to the limitation of the structure of the fuel tank and the fuel pump, when the fuel tank has an inclination angle, the fuel liquid level corresponding to the fuel pump float will inevitably change, resulting in a change in fuel resistance. [0004] The change of fu...
