无人车载以太网技术研究

Research on Unmanned Vehicular Ethernet Technology

摘要:

随着人工智能的高速发展，其相关技术已经运用到生产生活的很多领域，在无人平台上，人工智能已经不可或缺。无人车网络系统由于智能感知的并入，使得传统的总线通信技术难以满足发展要求。车载以太网的出现能为大量数据高集成的通信系统提供一种有效解决方案。无人车载网络系统采用时间触发以太网的架构来进行设计。首先考虑整个时间触发网络系统的通信节点，针对通信链路设计相应的通信板卡。在板卡方面，主要设计了TTE交换机、端节点子系统控制器，为了增加整个系统的可靠性，采用了三余度通信结构。根据控制器和交换机相应的功能进行软件开发，并通过系统测试验证，满足各个系统通信任务需求，验证了此无人车网络系统可行性和准确性。

Abstract:

With the rapid development of artificial intelligence, its related technologies have been applied to many fields of production and life, and artificial intelligence has become indispensable on the unmanned platform. Due to the integration of intelligent sensing, traditional bus communication technology is difficult to meet the development requirements of unmanned vehicle network system. The emergence of vehicle-mounted Ethernet can provide an effective solution for the communication system with large amount of data and high integration. The unmanned vehicle network system is designed based on time-triggered Ethernet. Firstly, the communication nodes of the whole time-triggered network system are considered and corresponding communication boards are designed for communication links. In the aspect of board card, TTE switch and end node point system controller are mainly designed. In order to increase the reliability of the whole system, three redundancy communication structure is adopted. The software was developed according to the corresponding functions of the controller and switch, and the communication task requirements of each system were met through system testing and verification. The feasibility and accuracy of the unmanned vehicle network system were verified.
