基于LIN网络的车门控制系统设计
【摘要】这几年汽车技术不断发展,汽车上的控制器也逐渐变多,为了提高数据传输的安全和可靠,减少连接导线,汽车网络技术随即产生。本文首先讲述为什么汽车网络技术一定会产生,并说明了车载网络的应用范围和主要类别,同时也介绍汽车网络技术的发展状况、特点和趋势。还对车身的网络控制系统进行了介绍。跟据上面所诉的内容提出了开发基于LIN网络的车门的控制系统的意义与必要性。
本文也详细讲述了LIN网络在硬件方面的设计。同时也考虑盗了了电磁的干扰和产生的原因并切提出了能使电磁的兼容性变高的一些方法和措施。然后又讲述了车载控制器的结构和优点,也分段阐述了LIN总线的通讯的控制程序和中央控翻器的节点应用程序和车门的控制器节点的应用程序的软件内容和设计。
文章充分利用了LIN总线在车身控制中所拥有的优势,设计了基于LIN网络的车门控制系统,同时也开发了相对应的软件和硬件,实现了车门、车窗和门锁的LIN网络的控制系统。

The door control system based on LIN network design
【Abstract】In recent years automotive technology development the car controller also gradually become more in order to improve the safety and reliable data transmission reduce the connection wire automotive network technology arises. This article first tells why the car network technology will be produced and illustrates the application range of the on-board network and the main categories, as well as the automotive network technology development status characteristics and trends. Also the body network control system are introduced. According to the above proposed the development based on the content of LIN. A network of car door control system of the significance and necessity.
This article also LIN network is described in detail in the design of the hardware. As well as consideration of the stolen procession of electromagnetic interference and reasons and put forward to make the electromagnetic compatibility of high some methods and measures. Then tells the story of on-board controller structure and advantages and they divided the LIN bus communication control program and the central control node application of double and the door of the application software of the controller node content and design.
This paper make full use of the LIN bus in body control has the advantages of car door control system based on LIN network was designed, at the same time also developed corresponding software and hardware, the door, window and door lock LIN network control system.
