Modeling and Traffic Scheduling Problems for In-Vehicle Time-Sensitive Network Communication Architectures

The traffic scheduling problems of in-vehicle electronic and electrical architectures are closely related to the reliability and real-time performance of in-vehicle communication. In order to solve the application problem of time-sensitive network (TSN) communication in the actual vehicle scene, a method of establishing the vehicle time sensitive network model is proposed. A traffic scheduling strategy based on the time shaping mechanism (TAS) is designed for the transmission of multiple types of information flows in the network architecture, and a low-latency and highly reliable traffic scheduling scheme is obtained by using a genetic algorithm. Finally, the feasibility of the scheduling strategy is demonstrated through simulation experiments.
