Design And Research Of Unmanned Freight Vehicles In Intelligent Transportation System

China's logistics industry is currently at the end of the "logistics hardware upgrade phase" and the initial stage of the "logistics cost management era".China's freight vehicles industry has begun to take shape,but compared with foreign advanced manufacturers,the structure of China's freight vehicles is not reasonable enough,product quality and technical level have yet to be improved.As the most flexible tool in transportation solutions,freight vehicles are the main force of road transport,it is imperative to keep up with the times to meet the needs of a more efficient and intensive logistics industry.This topic actively responds to a series of new ideas,new opinions and new theories put forward by Comrade Jinping Xi in the 19 th National Congress report on the new stage of China's development and the main contradictions facing the society.With the intelligent transportation system as the core,through the three major ways of new energy,automatic driving and car networking,create a safe,efficient,green and energy-saving Chinese highway freight system solution.Fully seize the opportunity of national development,promote the transformation and upgrading of the national logistics industry,and contribute to the national economic development and smart logistics system.The innovation of this paper is to analyze the characteristics of China's expressway operation,road conditions,industry norms and other factors,summarize the intelligent transportation system and unmanned technology concept for road conditions in China,and verify its feasibility to some extent.For the freight vehicles,through the investigation and analysis of domestic and international design cases,summarize the modeling trends of freight vehicles,clarify the true demand and design orientation of smart logistics for transportation vehicles,and the constraints in the design of freight vehicles.On this basis,the scheme type of the concept freight vehicles is determined through sketching and model building.The research of this subject can promote the specialization of Chinese freight vehicles,and verify that unmanned and high-tech equipment will be the development direction of future long-distance freight vehicles design and exploitation.
