作为车载网络与移动通信网络互联的相关软硬件产品的核心技术,车载网络与IPv6网络的网关设计是互联互通的基础,也是开发的难点。该文论述一种支持IPv6网络连接的控制器局域网络(CAN)应用层协议的设计过程,采用命令故障码表作为IPv6协议和CAN协议应用层级功能的映射工具,描述网关的软件处理流程。在车身开发中进行了具体实现,验证了网关的有效性和正确性。
As the core technology of the related hardware and software products that interconnects vehicle network and mobile communication network, the gateway design of vehicle network and IPv6 network is the foundation of interconnection and intercommunication, and also the difficulty of development. This paper discusses the design process of Controller Area Network (CAN) application layer protocol which supports IPv6 network connection. It uses command trouble code table as a mapping tool of IPv6 protocol and CAN protocol application level functions to describe the software processing flow of gateway. In the body of a concrete realization of the development to verify the effectiveness of the gateway and the correctness.
