基于CAN／LIN总线的汽车通信网络设计

随着人们对汽车各方面要求的不断提高，汽车上的电控系统数量越来越多，随之产生诸如电路复杂性增加、可靠性下降、生产成本增加等问题。为解决上述问题文中提出了一种基于CAN总线和LIN总线技术的现代汽车通信网络的低成本设计方案。设计中将CAN总线技术用于高速的驱动系统中，将LIN总线技术（其节点成本是CAN的1／3～1／2）用于低速的车身系统中，在器件选型上采用了PHILIPS和FREESCALE的典型汽车电子芯片，既实现了应有的网络控制功能，同时也降低了车辆电子系统的开发、生产和服务成本，具有较高的实用性。

Design of Communication Vehicle Network Based on CAN/LIN-bus

Nowadays, ECUs used in the automobile are greatly increased because of the people's increasing demands for a higher quality automobile. Therefore it brings many problems, such as the raising complexity of the electron circuit, the decreasing dependability and the increasing cost of the product. Solving the problems mentioned above, a new modern and low cost communication vehicle network is designed based on CAN-bus and LIN-bus in this essay. In the design the CAN-bus is used in the high speed driving system, while the LIN-bus(the cost is 1/31/2 of the CAN-buses') is used in the lower speed body controlling system of the automobile, and the chips used in the design choose the typical chips of PHILIPS and FREESCALE. The design not only can perform the control function, but also can reduce the cost of the development and production of the product and the services as well. It is a practical design.
