车载网关Internet化的设计与实现

Design and Implementation of the Gateway to Access the Internet

提出了一种基于CAN、LIN、MOST总线的车载网关设计方案。详细介绍车载网关在车身控制系统中的应用以及车载网关Internet化的设计与实现,对控制系统中出现的故障可实时记录并与网络服务器端进行数据的交互,并给出硬件实现和软件流程。该车载网关不但实现车身内部不同总线系统之间的数据通信,而且可以实现总线系统故障码的在线诊断。

A design project of the gateway embedded in the vehicle based on the CAN/LIN/ MOST bus is put forward. The application of the gateway in the body control system and the design and implementation of the gateway to access the Internet is introduced. And it can log all the problems occurred in the control system with the real-time pattern and it also can interchange data frames between web servers. Hardware realization and software flowchart are also presented. This gateway not only realizes the data communication between different bus systems embedded in the vehicle, but also realizes the real -time diagnosis of the DTC in the bus system.
