CAN总线控制器设计，CAN 是Controller Area Network 的缩写（以下称为CAN），是ISO国际标准化的串行通信协议。在当前的汽车产业中，出于对安全性、舒适性、方便性、低公害、低成本的要求，各种各样的电子控制系统被开发了出来。由于这些系统之间通信所用的数据类型及对可靠性的要求不尽相同，由多条总线构成的情况很多，线束的数量也随之增加。为适应“减少线束的数量”、“通过多个LAN，进行大量数据的高速通信”的需要，1986 年德国电气商博世公司开发出面向汽车的CAN 通信协议。此后，CAN 通过ISO11898 及ISO11519 进行了标准化，现在在欧洲已是汽车网络的标准协议。 -CAN bus controller design, CAN stands for Controller Area Network (hereinafter referred to as CAN) is a serial communication protocol of the ISO international standardization. The current auto industry, for safety, comfort, convenience, low pollution, low-cost requirements of a wide range of electronic control systems have been developed out. Different data types used for communication between the system and reliability requirements, multiple bus Harness the number increases. To adapt to " reduce the number of harnesses, a large number of high-speed data communication needs of the number of the LAN, in 1986 the German Electrical and Bosch developed the CAN communication protocol for automotive. Since then, CAN ISO11898 and ISO11519 standardization in the European automotive network standard protocols.
