Automobile fuel quantity signal indicating system and fuel quantity computing method

Abstract

The invention provides an accurate and highly reliable automobile fuel quantity signal indicating system and a fuel quantity computing method. According to the automobile fuel quantity signal indicating system and the fuel quantity computing method, the automobile fuel quantity signal indicating system comprises a fuel liquid level sensor, an engine control unit and an indicating unit which is provided with a memory module and a computation module. The indicating unit is respectively connected with the fuel liquid level sensor and the engine control unit. The automobile fuel quantity signal indicating system is formed merely by modifying the existing parts. The fuel quantity computing method can detect fuel liquid levels by using the fuel liquid level sensor in a static state, so that accurate detected values can be obtained, and moreover, actual fuel consumption can be acquired merely through an engine control system in the driving process, and thus the measured deviation of the fuel liquid level sensor under a bumping condition is removed to enable current residual fuel which is obtained finally through computation to be accurate as far as possible.

Description

technical field [0001] The invention belongs to the technical field of automobile electronics, and in particular relates to an automobile fuel quantity signal indicating system and a fuel quantity calculation method. Background technique [0002] With the progress and development of society, the number of automobiles in our country continues to increase. At the same time, automotive electronics technology has also entered an era of rapid development. In order to ensure the normal and safe driving of automobiles, people pay more and more attention to various display information of automobiles. Among them, the display information of the fuel gauge has received extensive attention. People need to know the current remaining fuel volume from the fuel gauge, so as to know the cruising range and ensure normal driving. Therefore, the accuracy of the fuel gauge indication has a great influence on the driver. [0003] The working principle of the current common fuel quantity calcu...

AI Technical Summary

Problems solved by technology

During the normal driving process of the car, there are various bumpy roads such as uphill and downhill, which affect the data collection of the fuel level sensor. It will interfere with the electric signal of the fuel gauge. The above factors will lead to inaccurate indication of the fuel gauge, and there may be a phenomenon that the pointer of the fuel gauge fluctuates, and the real-time performance is not good. Serious problems known to bring great inconvenience to the driver's driving
