Abstract

The invention provides a vehicle fuel calculation method and system, electronic equipment and a storage medium. The method comprises the steps that gyroscope data of a vehicle, liquid level data of a fuel tank and the fuel injection quantity are collected; judging whether the vehicle is in a stable driving state or a ramp driving state according to the gyroscope data, and if the vehicle is in the stable driving state, calculating the residual fuel quantity of the vehicle according to the liquid level data; and if the vehicle is in the ramp running state, the fuel injection quantity accumulated value during ramp running is calculated according to the fuel injection quantity, and the residual fuel quantity of the vehicle is calculated according to the final residual fuel quantity during stable running and the current fuel injection quantity accumulated value. Compared with the traditional fuel oil algorithm technology which only depends on oil floater detection, the scheme of the invention is more practical, and the residual fuel oil quantity which is more practical can be calculated in more complex road conditions, so that the problem of abnormal fuel oil display of the vehicle during climbing/downhill and cross-country bumping can be solved, the detection accuracy of the residual fuel oil quantity can be improved, and the detection efficiency can be improved. And the vehicle anchoring risk is reduced.

AI Technical Summary

Problems solved by technology

[0003] The traditional fuel algorithm only converts the resistance value collected by the oil float into the AD value for fuel judgment, which cannot be combined with the actual road conditions of driving. When driving on a slope, the tilt of the fuel tank causes errors in the AD value collected by the oil float, so that it cannot be accurately calculated. Identify the fuel status of the remaining fuel tank, resulting in falsely high or falsely low fuel consumption when driving on slopes
