Design And Implementation Of Intelligent Driving Collaborative Interconnection System

In recent years,the rapid growth of car ownership has led to serious road congestion and traffic safety problems.Therefore,connected vehicles,which use modern communication technology to realize environmental perception and sharing,have emerged at the right moment.Connected vehicles can acquire environmental perception information through sensors,cameras,positioning devices and other devices,and share perception information through V2X communication,so as to realize intelligent transportation management,intelligent dynamic information service,intelligent vehicle control and other services.Therefore,this thesis attempts to design and implement a connected vehicle system,which can improve road safety by providing traffic scenario warning service.In this thesis,firstly,an intelligent driving collaborative interconnection system is designed based on the architecture of connected vehicles,and then warning applications are developed based on the system to improve road safety.Finally,a communication security encryption scheme is proposed to ensure the information security of V2V communication.In this thesis,an intelligent driving collaborative interconnection system is designed on the basis of current architecture of connected vehicles,which can be divided into data acquisition module,V2V communication module,data processing module,vehicle-cloud interaction module and warning display module.Among them,V2V communication module and data processing module are the core functional modules.Based on LTE-V technology,the V2V communication module realizes real-time and efficient V2V communication function,and the data processing module provides data support and interfaces for warning application.The whole system satisfies the requirements of information interaction,environment perception,warning and decision-making through the cooperation of each module.In this thesis,based on the realization of intelligent driving collaborative interconnection system,the warning application is developed.In the warning application,four common traffic safety scenarios are selected,including forward collision warning,left-turn assist,emergency braking warning and traffic jam warning.Also,corresponding warning algorithms are designed for each scenario to ensure the availability,efficiency and universality of the system,and improve the safety of road transportation.Based on the security requirement of the system,a communication security encryption scheme is proposed,and verifies the feasibility of this scheme for V2V communication through scenario simulation.Then,the security of the scheme in the face of malicious attack is verified by the analysis of attack and defense.
