As the number of in-vehicle electronic devices and system complexity increases, it drives the evolution of the in-vehicle electrical/electronic architecture (E/E). The most promising future architecture is the zone architecture divided by physical location. Zones are connected via high-speed Ethernet, and time-sensitive networking enhances Ethernet in terms of real-time and determinism. In service-oriented communication methods, there are issues with quality assurance and data inconsistency. This paper addresses these issues by combining traffic scheduling strategies in time-sensitive networking, proposing an algorithm for quality assurance and data consistency. Simulation results demonstrate that, under the premise of satisfying the quality of service, the data stream of the same service can reach multiple subscribers simultaneously. This further demonstrates the feasibility and effectiveness of the proposed method.

面向服务的车载以太网数据一致性研究

随着车载电子设备数量和系统复杂性的增加，推动了车载电气/电子架构（E/E）的发展。未来最有前途的架构是按物理位置划分的区域架构。区域通过高速以太网连接，时间敏感的网络增强了以太网的实时性和确定性。在面向服务的通信方法中，存在质量保证和数据不一致的问题。本文通过结合时间敏感网络中的流量调度策略来解决这些问题，提出一种质量保证和数据一致性的算法。仿真结果表明，在满足服务质量的前提下，同一业务的数据流可以同时到达多个用户。这进一步证明了所提方法的可行性和有效性。
