Problems solved by technology

[0002] Nowadays, the fuel sensors used in automobiles are divided into fuel sensors with different characteristics such as swing arm fuel sensors and reed switch fuel sensors. Due to their own characteristics, fuel sensors will output signals with different characteristics under the same conditions. Combination instrument Many different components need to be set up to process signals with different characteristics, so the time and cost of developing the instrument cluster will increase
At the same time, the driving of the car under various road conditions will cause signal fluctuations, resulting in abnormal jitters displayed on the instrument, and the inaccurate display of this kind of fuel is likely to mislead observers

Embodiment Construction

[0025] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present invention, and not to limit the present invention.

[0026] figure 1 It is a flowchart of the method for processing automobile fuel quantity signal provided by the present invention. Such as figure 1 As shown, the processing method includes the following steps: (S1) continuously collect the fuel quantity signal from the fuel sensor 1 with a sampling period t to obtain the fuel quantity detection value corresponding to each sampling point; (S2) calculate the i-th sample The fuel consumption value V(i) in the period t(i); (S3) determine whether the fuel consumption of the vehicle is in a normal state or an abnormal state according to the fuel consumption value V(i); and (S4) correspond to the determined state Ground control ...

Abstract

The invention discloses an automobile fuel signal processing method and an automobile fuel signal processing system. The method includes the steps: (S1) continuously acquiring fuel signals from a fuel sensor by a sampling period t to acquire a fuel detection value corresponding to each sampling point; (S2) calculating a fuel consumption value V (i) in an ith sampling period t (i); (S3) determining whether automobile fuel consumption is in a normal condition or an abnormal condition according to the fuel consumption value V (i); (S4) correspondingly controlling a fuel tank fuel display value Vdis (i) in the ith sampling period t (i) according to the determined condition. By the automobile fuel signal processing method and the automobile fuel signal processing system, burden of a combination instrument is relieved, development cycle of the combination instrument is shortened, development cost is saved, and the problem of dither fuel signals is solved to enable an observer to acquire accurate fuel tank fuel conditions.

Description

Technical field [0001] The invention relates to the field of automobile electrical, in particular, to a method for processing an automobile fuel quantity signal and an automobile fuel quantity signal processing system. Background technique [0002] Nowadays, fuel sensors used in automobiles are divided into fuel sensors with different characteristics such as swing arm fuel sensors and reed switch fuel sensors. Due to their own characteristics, fuel sensors will output signals with different characteristics under the same conditions. Combination instrument Many different components need to be set up to process signals of different characteristics, so the time and cost of developing a combination meter will increase. At the same time, the car driving under various road conditions will cause signal fluctuations and cause abnormal jitter in the meter display. This inaccurate display of the fuel level can easily mislead the observer. Summary of the invention [0003] The purpose of th...
