Embodiment Construction

[0014] The present invention will be described in detail below in conjunction with the accompanying drawings and with the best embodiment.

[0015] refer to Figure 1-4 , the control method of the automobile fuel gauge, including: fuel gauge damping control, fuel gauge flameout refueling control, fuel gauge ignition refueling control, low fuel alarm control; wherein:

[0016] (1) Fuel gauge damping control method, refer to figure 1 , first the instrument ignites, and at this time the instrument samples the external fuel resistance signal, sampling once every 100 milliseconds, sampling 10 times, and processing the sampled value, removing the maximum value and minimum value, and replacing the maximum value and minimum value with the second maximum value and the second minimum value value, and then average the 10 sampling values ​​to ensure the accuracy of fuel sampling data, and according to the calculated data, the pointer of the fuel gauge quickly indicates the corresponding ...

Abstract

The invention discloses a control method for an automobile fuel gauge, relating to a control method for an automobile instrument. The control method comprises: (1) a fuel gauge damping control method, which comprises the following steps of: igniting an instrument, sampling, processing a sampling value and then judging speed; (2) a fuel gauge flameout refueling control method, which comprises the following steps of: keeping the instrument wait for 8 seconds after flameout and then sampling the fuel gauge, wherein no refueling is indicated if the fuel volume is less than 1 / 8 of the volume of an oil tank, and a fuel pointer still indicates a position indicated by the fuel gauge before flameout, namely a position corresponding to V1; if the fuel gauge is still in a flameout state, the fuel gauge judges whether a fuel signal is invalid, namely whether the fuel gauge is in an open circuit sate or a short circuit state; and then the fuel gauge indicates according to a damping strategy; (3) a fuel gauge ignition refueling control method, wherein the fuel gauge is used for indicating according to the damping strategy; and (4) a low fuel alarm control step, which comprises low fuel alarm and low fuel alarm disappearance. The control method disclosed by the invention guarantees that the fuel gauge stably works under various conditions and accurately indicates the volume of the fuel.

Description

technical field [0001] The invention relates to an automobile instrument control method, in particular to an automobile fuel meter control method. Background technique [0002] The fuel gauge is a relatively difficult control unit in the car instrument display system. During the driving process, due to the shaking of the whole vehicle, the volume of the fuel tank changes, which also leads to the unstable sampling value of the fuel signal by the instrument. However, if the pointer of the fuel gauge is based on the actual sampling value in real time, it may cause the fuel pointer to go up and down, and the low fuel alarm to go on and off. And the fuel gauge also needs to consider the refueling situation, how to judge whether it has been successfully refueled or just caused by the shaking of the fuel tank. If it is not handled properly, it will cause complaints from customers. This requires a complete fuel gauge control strategy to ensure the precise work of the fuel gauge. ...
