N2 - With the rapid development of the electronic and electrical architecture of intelligent and con- nected vehicles,the demand for real-time reliability in in-vehicle communication networks has significantly in- creased. In this context,Time-Sensitive Networking(TSN)has become a critical technology to meet the demand. In this paper,the implementation of the IEEE 802.1CB protocol in vehicular networks is realized,filling the gap in current research regarding the combined use of link redundancy transmission and routing planning. An innovative multi-path routing strategy is proposed which balances network efficiency and reliability through dual-path transmis- sion involving both primary and redundant paths. The core contribution of this study includes:(1)a novel NSGA2-based primary path routing algorithm,which achieves the dual objectives of load balancing and low latency through intelligent path planning,and(2)an improved Dijkstra-based redundant path routing algorithm,which ensures high-reliability transmission for information flows with varying priority levels. Finally,a hardware-software integrat- ed experimental framework is proposed,demonstrating that the proposed algorithms outperform existing comparison algorithms by 18.19% to 62.29% in terms of load balancing and end-to-end latency,while also enhancing network reliability by 19.18% to 42.87%.
