Description

In a software-defined vehicle (SDV), where software controls all of the vehicle behaviors, heterogeneous communication flows with different characteristics share a single in-vehicle network. While Time-Sensitive Networking (TSN) is promising to prevent interferences among the flows, conventional network design methods for TSN require huge computational effort. To reduce computational complexity, we propose “time and bandwidth division flow assignment method” where the communication resource is partitioned based on the characteristics of the communication flows. By the evaluation, we confirmed our method could generate network design within one second satisfying all of the communication requirements supposing autonomous driving level 2.
