Problems solved by technology

During the driving trip, due to some complex and bad driving behaviors of the driver, such as bad shifting driving (high to low gear, low gear to high speed and high to low speed), slamming on the accelerator, frequent braking, long-term idling, frequent merging, frequent rapid acceleration ( Deceleration) and speeding, etc., resulting in reduced fuel utilization

Abstract

The present invention provides an evaluation method and device of automotive fuel economy. The method comprises a step of establishing a neural network regression calculation model and obtaining a fuel economy probability sequence according to a vehicle speed data sequence, an instantaneous fuel consumption data sequence, an engine rotation speed data sequence, an acceleration data sequence, the neural network regression calculation model, and a fuzzy probability mapping model, and a step of comparing each fuel economy probability in the fuel economy probability sequence with a preset probability threshold orderly, and evaluating the automotive fuel economy according to a comparison result. Through the method and the device, the automotive fuel non-economic process in an automotive driving process can be effectively identified, the automotive fuel economy is evaluated according to the automotive driving data corresponding to the automotive fuel non-economic process, and an automotive 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...
