Abstract

The invention relates to the technical field of automobile electronic control, and provides a control method for an automobile fuel gauge. The control method comprises the steps that a resistance value input signal transmitted by a fuel sensor is received; control is conducted in a micro-step mode when the speed of an automobile exists, the fuel gauge is adjusted when parking is conducted, and different control modes are adopted under the conditions that parking is conducted, and an engine rotates and does not rotate. According to the control method for the automobile fuel gauge, different modes are used for controlling the fuel gauge according to the speed of the automobile and the rotating speed of the engine, the technical problem that calculation of the fuel quantity of an existing automobile fuel gauge is not accurate can be effectively solved, the situation that corresponding fuel quantity calculation modes are provided for the fuel gauge under various road conditions is guaranteed, and the phenomenon that reading of the fuel gauge is not accurate is avoided.

Description

technical field [0001] The invention relates to the technical field of automobile electronic control, in particular to a control method of an automobile fuel gauge based on analog signal acquisition, processing and storage technology. Background technique [0002] The car fuel gauge can record and display the current amount of fuel in the car's fuel tank, which can be divided into fuel consumption and / or fuel remaining. Because the fuel gauge is very cumbersome to deal with, many cars have inaccurate fuel gauge readings. If the fuel Inaccurate meter readings may cause the car to run in a state of insufficient fuel, which may cause the car to turn off due to sudden exhaustion of fuel and break down, which increases the risk of car collisions and brings consumers unnecessary loss. Contents of the invention [0003] The invention solves the technical problem of inaccurate calculation of the fuel quantity in the existing automobile fuel gauge, and provides the following techn...
