| 摘要: |
| 智能网联汽车(Intelligent Connected Vehicle,ICV)是未来汽车行业发展的主要方向之一，其对车载网络通信的带宽、延迟出了较高的要求。针对该要求，提出了基于以太网的电子电气架构(Electronic/Electrical Architecture,EEA)；在分析基于IEEE802.1Qbv的时间敏感网络(Time-sensitive Networking,TSN)传输调度机制的基础上，实现了控制数据流和传感器数据流的增量式调度。通过评估和对比，TSN拥有更高的带宽、更低的传输时延，有望成为下一代车载网络。 |

| Abstract: |
| Intelligent connected vehicle(ICV) is one of the main development directions of the automotive industry in the future.It has high requirements for the bandwidth and delay of vehicular network communication.An electronic/electrical architecture(EEA) based on Ethernet is proposed to meet this requirement.According to the analysis of the transmission scheduling mechanism of time-sensitive networking(TSN) based on IEEE 802.1Qbv,the incremental scheduling of control data flow and sensor data flow is implemented.Evaluation and comparison show that TSN has higher bandwidth and lower transmission delay,and it is expected to become the next generation of vehicular network. |
