【摘要】 文章针对总线式车身系统设计,对CAN/LIN混合网络进行深入研究,给出车身混合网络结构及主控节点的设计与实现。在车身控制系统中,将CAN总线连入高速驱动系统,LIN总线连入低速车身系统中,通过主控节点将二者构建成混合控制网络,使其控制系统兼具可靠性、高性能和低成本优点。在器件选型上采用FREESCALE典型汽车电子芯片和智能触点检测模块,既实现了可靠网络控制功能,同时也可降低车辆电子系统的开发、生产成本,具有较高实用性。更多还原

【Abstract】 The paper considers the vehicle body control system design of bus style.A thorough study is made of the CAN/LIN mixed bus network.The design and implementation of the bodywork mixed network and the center control unit are described.In the bodywork control system,the CAN bus is connected to the high-speed drive system and the LIN bus to the low-speed bodywork system,and a mixed bus control network is set up with the help of the center control unit so that the control system has such advantages as high reliability,high performance and low cost.The system realizes reliable network control by adopting Freescale’s automobile electronic chips and intelligent chips,and the development and production cost of the automobile electronic system is reduced.更多还原
