基于CAN/LIN总线的车身网络控制系统

Research and Application of CAN Bus in Automobile Network System

对CAN(Controller Area Network)/LIN(Local Interconnect Network)总线做了详细介绍,设计了汽车CAN节点、LIN节点硬件电路,完成了CAN/LIN网关的硬件设计,LIN设计目标作为CAN的下层网络,同CAN相结合构成汽车分层通信网络结构。对车身网络控制节点软件进行了设计,该车身网络控制系统在网络通信中充分实现了数据共享。

The CAN（Controller Area Network） bus and LlN（Iocal Interconnect Network） bus are introduced in detail. The hardware circuits of CAN/LIN bus are designed, and hardware design of CAN/LIN gateway is finished. The aim of LIN is to be the low network of CAN, and bed communication network frame of automobile is formed with CAN and LIN bus. The software of body network control node is designed. Data share is fully realized in network communication of body net work control system.
