Abstract: The vehicle's Electrical/Electronic Architecture (EEA) serves as the foundation for implementing various functions of intelligent vehicles. This paper analyzes and summarizes the layout of the distributed vehicle EEA and discusses the advantages of Time-Sensitive Network (TSN) in the field of in-vehicle communications. Building upon the analysis, this paper combines the advantages of function-oriented and zone-oriented EEA and proposes a function-zone EEA for TSN. Four EEA network topology forms are evaluated based on communication delay, network load, cost and flexibility. Based on the OMNET++ framework, this paper conducts simulation verification of autonomous driving and body control data flows. The results show that the ring and mesh network topology can significantly reduce communication delays, enabling high-speed and scalable transmission for invehicle communication.
