Abstract

The invention provides a method and device for assessing economic efficiency of automobile fuel. The method for assessing the economic efficiency of the automobile fuel comprises the steps that a multiple regression model is established; an automobile speed data sequence in travelling of an automobile is acquired, and an acceleration data sequence is acquired according to the automobile speed data sequence; a probability sequence of the fuel economic efficiency is obtained according to the automobile speed data sequence, the acceleration data sequence, the multiple regression model and a fuzzy probability mapping mode; each fuel economic efficiency probability in the fuel economic efficiency probability sequence is successively compared with a preset probability threshold, so that comparison results are obtained; and the automobile fuel economic efficiency is assessed according to the comparison results. By the method and the device provided by the invention, automobile fuel non-economic courses in the automobile travelling can be effectively recognized; the automobile fuel economic efficiency can be assessed according to automobile travelling data information corresponding to the non-economic courses of the automobile fuel; and automobile driving experience is improved.

Description

technical field [0001] The invention relates to the technical field of automobiles, in particular to a method and device for evaluating fuel economy of automobiles. Background technique [0002] Automobile is an indispensable high-efficiency means of transportation in our modern society, and its transportation efficiency depends to a large extent on the power of the automobile. At the same time, with the rapid development of our country's economy, how to save fuel and reduce energy consumption has become a problem that our country must face. As the main body of fuel consumption, automobiles are the first to face many technical requirements to reduce fuel consumption and improve fuel economy. Therefore, it is particularly important to reduce the fuel consumption of automobiles as much as possible under the premise of ensuring power. [0003] Under the condition of the same technical condition of the vehicle, the level of driving skill has a great influence on the fuel savin...
