Processing method of automobile fuel quantity signal and processing system of automobile fuel quantity signal

Abstract

The invention discloses a method for processing the fuel quantity signal of an automobile and a processing system for the fuel quantity signal of the automobile. The processing method includes the following steps: (S1) continuously collect the fuel quantity signal from the fuel sensor with the sampling period t, so as to obtain the fuel quantity detection value corresponding to each sampling point; (S2) calculate the ith sampling period t( i) the fuel consumption value V(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) control the first The display value Vdis(i) of the fuel volume of the fuel tank for the i sampling period t(i). The method and system for processing the fuel quantity signal of an automobile provided by the present invention reduce the burden on the combination meter, shorten the development cycle of the combination meter, save development costs, and solve the jitter problem of the fuel quantity signal, so that the observer can Know the exact fuel tank condition.

Description

technical field [0001] The invention relates to the field of automobile electrics, in particular to a method for processing an automobile fuel quantity signal and a processing system for the automobile fuel quantity signal. Background technique [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 installed 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 on the instrument display. This inaccurate display of the oil quantity is likely to mislead the observer. Conten...
