Problems solved by technology

This method is simple and cannot simulate the resistance value change of the fuel sensor in various road conditions, so it is very difficult to use a variable resistor on the station to verify the correctness of the fuel gauge indication
[0006] Verifying the correctness of the fuel gauge indication on a real vehicle is time-consuming, laborious and inefficient

Abstract

The invention provides an automobile fuel meter indicating method and a verifying device and method thereof. The automobile fuel meter indicating method comprises the steps of judging that an automobile is in the non-stable state, executing the next step, wherein the non-stable state includes the jolting state, the uphill / downhill state, the hill stopping state and the bending state; calling a non-stable state remaining oil amount algorithm for calculating the corresponding remaining oil amount; performing displaying on a fuel meter according to the remaining oil amount. The fuel meter indication and verification accuracy is achieved, and the automobile meter development progress is accelerated.

Description

technical field [0001] The invention relates to the technical field of automobile instruments, in particular to an indication method for an automobile fuel gauge and a verification device and method thereof. Background technique [0002] The fuel gauge is an instrument used by fuel vehicles to indicate the current remaining fuel. Its basic principle is that the float in the mailbox moves up and down to drive the resistance sliding tap to rotate, thereby changing the output resistance of the fuel sensor, and then changing the display position of the pointer of the fuel gauge. . [0003] From the structure of the fuel gauge, it can be known that when the vehicle is on a non-stable road section, if it is not handled properly, the pointer of the fuel gauge will not be able to indicate smoothly. Therefore, in the design of the fuel gauge, the focus is on judging that the current vehicle is in various unstable states, using appropriate algorithms to calculate the remaining fuel v...
