A Study On The Application Of Blockchain Technology In The Cloud-Controlled Autonomous Driving System

Urban traffic is facing increasingly severe problems,such as traffic jam and accidents,air pollution,energey consumption and parking difficulty.Autonomous driving is now a hot research field,as it promises to create an ordered,efficient,safe,convenient,comfortable urban traffic system.V2V autonomous driving system is of high cost and difficult to manage.With the advance of communication technology such as 5G,autonomous driving system is transforming from V2V(car-centered)to V2N(intemet-centered).However,currently the cloud-controlled autonomous driving system is developed by isolated organizations or companies.This leads to problems such as complicate,high integration,information blockage,slow iteration speed,difficult maintenance and so on.Therefore,the net-connected cloud-controlled autonomous driving system needs to be decentralized and coordinated by multiple participants.Also it badly needs an effective mechanism for secure sharing of services and data.This thesis studies the application of the blockchain technology,and uses it to build a sharing environment of openness,collaboration,equality and security,and results in an stratified,modular,decentralized,assembled synthetic network of cloud-controlled autonomous driving system.The work of this thesis mainly includes:(1)Application scenario analysis and architecture design of net-connected cloud-controlled autonomous driving system using blockchain technology.We propose a simplified,hierarchical,open,scalable and sustainable system architecture which uses blockchain technology to realize the secure services and data sharing for the net-connected autonomous driving system.(2)The implementation of blockchain technology to realize sharing services and data safely.First,we analyze the difficulties and security problems of services and data sharing,then design and implement intelligent contract to ensure the safe sharing.In addition,cloud-based services and data sharing development tools are provided for easy communicating with sharing network.Finally,decentralized management of the sharing network is achieved through the micro-platform.(3)Experiment and result analysis.We verify the security and feasibility of services and data sharing based on the blockchain technology of net-connected cloud-controlled autonomous through the application of auto-parking system.
