局部互联网（LIN）在汽车控制系统中的应用

Application of Local Internet （LIN） in Automobile Control System

由于控制器局域网（通常称为CAN总线）的成本较高，在汽车控制网络中全面采用将会提高其生产成本，而局部互联网（通常称为LIN总线）是一种新型的低成本汽车车身控制网络，它可作为CAN总线的一种辅助网络。作者介绍了LIN总线的概况和目前的发展状况，举例说明了它在汽车电控系统中的应用。实践表明，在汽车控制系统中采用LIN，可以简化系统结构，提高系统的整体性能，更好地满足汽车控制功能的需求。

Due to the high cost of Controller Area Network （generally, it is called CAN bus）, the all-sided adoption of it will increase the cost of automobile production, but local Internet （generally, it is called LIN bus） is of a new-type and low-cost network for automotive body control, which can be used us a subsidialy network of CAN bus. The author introduces the general situation and present development of LIN, by illustrating its application in automobile electronic control system. The application proves that the system structure can be simplified, the integrated performance of the system can be enhanced and requirements of automobile control function are better met by means of LIN in automobile control system.
