Abstract: 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 in-vehicle time-sensitive networking are analyzed, which are mainly reflected in the strict communication performance requirements of electronic and electrical architecture, complex multi-stream hybrid scheduling, difficulties in integrating time-sensitive networking and the fifth generation of mobile communications system-Internet of Vehicles, and imperfect tool chain. Based on these challenges, the development trend of in-vehicle time-sensitive networks is prospected.

Key words: in-vehicle network, time-sensitive networking, in-vehicle time sensitive network, electrical and electronic architecture, traffic scheduling
