摘要
针对目前国内主机厂缺乏CAN/LIN网络的设计能力,提出基于OSEK/VDX规范的车身CAN/LIN网络的设计方法,设计了典型的车身网络架构,定义了帧的传输类型,对间接网络管理作了深入的研究,并且给出了间接网络管理中监督帧的设计方法及具体实现方式。同时对网络状态作了阐述,完善了网络管理的内容。最后利用CANoe软件仿真和实物ECU进行了仿真和测试。
Because the domestic carmakers are lack of the ability of designing CAN/LIN network, a method of designing the vehicle body CAN/LIN network is introduced based on the OSEK/VDX standard, and a typical topology is designed. The author defines the transmitting type of frame and makes an intensive study on indirect network management. The design method of supervision frame in the management is provided as well as its implementation. The network state is also elaborated to perfect the detail of network management. Finally the method is simulated and tested by using the CANoe software and real ECUs.
