Design And Implementation Of The Multi-level Intelligent Vehicle Sharing System Based On User Portrait

Vehicle sharing system is a technical solution to solve the problem of urban pollution and traffic congestion,which helps users share own vehicles or rent vehicles.There have been many researches and practice in cases of sharing and field of transportation.Zhejiang University Intelligent Vehicle Research Center developed a kind of smart electric vehicles equipped with intelligent hardware and software platform,which achieves the functions including driving data collection,virtual key to start and shut down vehicles and other functions,to support vehicle sharing system.This thesis presents a Multi-level Intelligent Vehicle Sharing System(MIVSS)based on the user portrait,and according to its characteristics,this thesis analyzes the system design and implementation.The main contents are summarized as follows:(1)The user portrait model is established,and the user portraits are described by collecting the user's basic information and dynamic driving information.And then characterizes users from user identity,behavior preference,driving skill,credit history and driving behavior.(2)This thesis proposes a multi-level sharing model based on user portraits,and designs site-free vehicle leasing mode,vehicle sharing mode based on rights management and private vehicle time-sharing mode for different application scenarios,and proposes the overall architecture of the system.(3)Analyze the characteristics of the shared system,analyze the technical problems that the hardware and software platform,server and client need to solve,and give a detailed design and implementation.(4)Design the simulation platform and the experiment under the real environment to verify the accuracy and efficiency of the model,and the validity and reliability of the design of the whole shared system,and put forward the shortcomings and improvement direction of this thesis.
