摘要
以汽车控制局域网CAN总线为基础,结合单片机原理,对奥迪汽车前照灯传统的点对点控制电路进行改造,实现了只用2根信号线就可以对奥迪汽车前照灯进行控制;设计出了一套完备的总体电路图,依据电路图设计并制作出2个带有CAN总线节点的PCB电路板;实现CAN节点与PC机的通讯,在PC机上能观察到节点报文的发送和接收,实现CAN总线3个节点构成的一个小网络的数据传输。
Based on automotive LAN CAN-bus, the traditional point-to-point control circuit for AUDI headlamp is transformed to two signal wires according to the singlechip principle. The overall circuit diagram is designed and two PCB boards with CAN-bus nodes are made.Thus communication between the CAN-bus nodes and PC and the data transmission between three nodes of the CAN bus are realized.
