Metering assisting system and metering method for automobile fuel meter

Abstract

The invention discloses a metering assisting system and a metering method for an automobile fuel meter, and belongs to an assisting device for the automobile fuel meter. The system comprises a signal conversion module, a central processing module and a display control module, wherein the display control module and the signal conversion module are connected with the central processing module respectively; the central processing module is also connected with a power supply and a storage device; the power supply is used for supplying power to the whole system; the signal conversion module is used for outputting a converted automobile fuel capacity digital signal to the central processing module; the central processing module is used for storing the fuel capacity digital signal into the storage device, and simultaneously outputting the fuel capacity digital signal to the display control device; and the display control device is used for converting the fuel capacity digital signal into a visual image. The metering assisting system for the automobile fuel meter has a simple structure, and can be integrated in a fuel path system of any vehicle type. The metering method for the system is definite and wide in application range.

Description

technical field [0001] The invention relates to an auxiliary device for a fuel gauge of an automobile, more specifically, the invention mainly relates to a metering auxiliary system for a fuel meter of a car and a metering method thereof. Background technique [0002] With the continuous development of my country's automobile industry, the improvement of various parts and auxiliary devices on the automobile is also emerging one after another, but the improvement on its fuel gauge is far from the rapid development of other parts and components. There are various deficiencies in the meter. For example, the popular one of the commonly used automobile oil meter is that a float is installed in the fuel tank, and a metal rod is connected on the float. The tail of the metal rod is connected to a The variable resistor is connected to the fuel gauge of the car, and the change of the position of the buoy is reflected in the change of the resistance value of the variable resistor, and th...

AI Technical Summary

Problems solved by technology

Although this car fuel gauge solves the disadvantages of the popular car fuel gauge, its installation is still complicated, and the cost is still high because of the need to install sensors.

[0003] At the same time, due to the complicated installation, high cost, low display accuracy, poor anti-interference ability, and unintuitive display of the commonly used automobile fuel gauge; moreover, the public vehicles of government agencies, enterprises and institutions, and logistics companies have virtual reality in terms of fuel consumption. Problems such as invoicing and private use of public vehicles have reduced the efficiency of vehicle management and affected the financial management and accounting of the unit
