摘　　要：在研究汽车内部CAN/LIN总线组网原理的基础上,分析了2种汽车总线互连的关键点与难点——汽车网关.针对采用多个分立网关集成度较低的缺点,提出了一种基于ARM7的集成网关方案,并详细阐述了该方案的软硬件实现方法.实验室组网实验表明:该网关不仅能顺利实现高速CAN总线、低速CAN总线和LIN总线的互连,而且集成度高、性能稳定.Based on thorough study of the networking principle of both CAN and LIN bus, the difficult and critical issues regarding the bus interface for two vehicles, that is, vehicle gateway, are analyzed in this paper. To tackle the drawbacks identified in the current several-gateway scheme, typically the low integration level resulting from the use of multi-independent gateways, this paper proposes a new integrating gateway scheme based on ARM7, and presents its efficient implementation by both software and hardware means. Experimental results indicate that the interconnection among high speed CAN bus, low speed CAN bus and LIN bus can be successfully accomplished using the proposed scheme with sufficiently high stability and integration level.
