如今，车载网络设计已经成为一个困难的挑战，由于增加的复杂性和严格的实时性约束。在这项工作中，我们提出了一个集成的框架，实时约束下的CAN网络拓扑设计。该框架集成了拓扑设计和实时分析。它首先通过整数线性规划（ILP）优化将电子控制单元（ECU）自动分配到其中一条CAN总线。然后，实时分析的最坏情况响应率（WCRR）的结果被反馈到一个加权的ILP优化，以进一步提高拓扑设计的实时性。通过对汽车制造商的真实的消息集的实例研究，验证了该框架的有效性和可扩展性。
Nowadays, in-vehicle network design has become a difficult challenge due to increased complexity and strict real-time constraints. In this work, we propose an integrated framework for CAN network topology design under real-time constraints. The framework integrates topology design with real-time analysis. It firstly allocates electronic control units (ECU) automatically to one of the CAN buses via integer linear programming (ILP) optimization. Then, the worst case response rate (WCRR) results of real-time analysis are fed back to a weighted ILP optimization to further improve the topology design with respect to a realtime property. A case study using a real message set from automaker validated the effectiveness and scalability of the proposed framework.
