总线技术在汽车上的应用及标准

Application and Standard of The Bus Technology in car

总线技术已经成为现代汽车的标准技术,几乎所有的车都开始采用CAN/LIN总线.总线零部件也成为发展的主流.汽车总线系统实质上是通过某种通讯协议(如CAN协议),将汽车内部的各个ECU(电子控制单元)节点连结起来,从而形成一个汽车内部的局域网络.节点根据自身的传感器信息以及总线上的信息,完成预定的控制功能和动作,如灯光的开闭、电机启停等.节点之间的通讯通过总线来实现.

The bus technology has become the standard of modern automobile. Almost all the cars use CAN /LIN bus. Bus parts also become the mainstream. In essence,bus system connects each ECU( electronic control unit) node of the car through a kind of communication protocol( such as CAN agreement),thus forming a local area network in the car. According to its own sensor information and bus information,node completes the schedule control function and action,such as opening /closing light,starting /stoping motor. The communication between nodes are achieved by bus.
