车载时间敏感网络:现状与展望

Automotive In-Vehicle Time-Sensitive Networking:the State of the Art and Prospect

总结了车载时间敏感网络的研究现状,包括时间同步、流量调度、可靠性与安全和资源管理等关键技术,以及电子电气架构、综合设计和车辆对外通信等应用场景;指出了车载时间敏感网络应对的挑战,主要体现在电子电气架构的通信性能要求严格、多流混合调度复杂、时间敏感网络和第5代移动通信系统-车联网融合困难以及工具链不完善等方面,基于这些挑战展望了车载时间敏感网络的发展趋势。

In order to facilitate researchers in both network and automotive fields to have a comprehensive understanding of the automotive in-vehicle time-sensitive networking,this paper summarizes the current research status of the automotive in-vehicle time-sensitive networking,including key technologies such as time synchronization,traffic scheduling,reliability and security,and resource management,as well as application scenarios of electrical and electronic architecture,integrated design,and external vehicle communications.Challenges faced by the automotive in-vehicle time-sensitive networking are analyzed,which are mainly reflected in the strict communication performance requirements of electrical and electronic architecture,complex multi-stream hybrid scheduling,difficulties in integrating time-sensitive networking and the fifth generation of mobile communications system-vehicle to everything,and imperfect tool chain.Based on these challenges,the development trend of the automotive in-vehicle time-sensitive networking is prospected.
