Analysis method and device for fuel economic efficiency of heavy truck

Abstract

The invention discloses an analysis method and device for the fuel economic efficiency of a heavy truck. The method comprises the following steps that: calculating the driving duration of heavy trucksat different speed ratios under a corresponding high-gear position state, wherein the high-gear position state is jointly decided by an s / v interval and a v range; abandoning an economic revolving speed definition of a traditional meaning, carrying out statistics and analysis by a laboratory by aiming at different vehicle models to obtain an optimal revolving speed range; obtaining the data of the speed v and the weight of the heavy truck in a continuous time period; selecting weight obtained at a moment of the highest speed v in the continuous time period to serve as the weight of the heavytruck in the continuous time period, and accumulating the driving mileage of the heavy truck under the weight; and finally, according to the preset urea box volume and the urea liquid level data of the heavy truck, calculating the practical urea consumption of the heavy truck, and comprehensively analyzing the fuel economic efficiency of the heavy truck. The method deduces the high oil consumptionfactor of the heavy truck from multiple dimensions, and accurately provides a theoretical basis and data support for the logistics industry to save oil consumption cost and normalize the driving behaviors of drivers.

Description

technical field [0001] The present application relates to the technical field of Internet of Vehicles, in particular to a method and device for analyzing fuel economy of heavy-duty trucks. Background technique [0002] The fuel consumption of heavy-duty trucks is the most concerned issue for car owners, because it involves the cost of personal or business operations. Accurate analysis of the main factors that cause high fuel consumption of heavy-duty trucks will help improve the driving habits of car owners, and provide data support for timely repair and maintenance of vehicles, which is conducive to reducing fuel consumption. [0003] At present, the basic market usually analyzes the impact on the fuel consumption of heavy-duty trucks from the aspects of high-end position, economic speed range, reference weight and urea tank volume. Among them, the high gear is determined by the ratio of the speed to the speed and the speed, and the economic speed range is different for ve...
