基于CAN/LIN总线的车载通信网络设计

Design of Communication Network in Vehicle Based on CAN / LIN

汽车上的电控系统数量越来越多,为了提高电控单元之间互相通信性能和降低导线成本,提出了一种基于CAN/LIN总线的车载通信网络,将CAN总线网络应用在高速的驱动系统,LIN总线网络应用在低速的车身车灯控制系统,两者通过网关进行数据交换.仿真测试表明,本车载通信网络的设计合理,通信可靠,能够实现CAN/LIN总线网络之间的数据传输.

As the number of electronic control systems on automobiles continues to increase,in order to improve the mutual communication performance among electronic control units and reduce the cost of wires,this paper discusses one communication network in vehicle based on CAN and LIN. The CAN bus network is used in the high-speed driving system. The LIN bus network is used in the low-speed body and lamp controlling system. Both bus systems exchange the data by a gateway. The simulation test proves that this design is reasonable and reliable,which can realize the data transmission between CAN bus network and LIN bus network.
