Automobile fuel gauge display strategy compatible with various road conditions

Abstract

An automobile fuel gauge display strategy compatible with various road conditions comprises the steps that firstly, a vehicle is self-detected, the indication of a fuel gauge is detected to be correct, and meanwhile signals of a fuel level sensor can be received, secondly, the mode of the fuel gauge is judged according to the rotating speed of an engine and the running speed of the vehicle, and thirdly, the mode of an idle speed is judged. In the first step, in the driving mode, signals of the oil level sensor are collected with 15 s as a period, and an indicated value of the oil gauge is obtained through calculation; in the driving mode, signals of the oil level sensor are collected with 10 s as a period, and the indicated value of the oil gauge is obtained through calculation. According to the design, computer-aided calculation can be carried out through the combination instrument, the display stability and accuracy of the fuel gauge are effectively improved, the situation that the fuel gauge displays incorrectly due to the fact that the fuel tank is not located at the horizontal position under various road conditions such as the uphill road section and the downhill road section can be avoided, and the display accuracy of the fuel gauge is effectively improved.

Description

technical field [0001] The invention relates to a fuel quantity display technology, in particular to a vehicle fuel gauge display strategy compatible with various road conditions, and is particularly suitable for a fuel gauge display strategy with accurate indication and stable display. Background technique [0002] The car combination instrument is the main basis for the driver to intuitively understand the various system parameters of the current car operation. The fuel gauge is an important part of the combination instrument, which can display the fuel consumption and the function of fuel alarm for the convenience of the driver. Generally, there are high requirements for the accuracy of its display. When the fuel gauge shows that it is lower than the actual remaining fuel, it will cause users to feel that the fuel consumption of the vehicle is too high. When the fuel gauge shows that it is higher than the actual remaining fuel, it will cause user errors. Judge remaining m...
