CAN总线系统实践教学初探

A preliminary study on the practice teaching of CAN bus system

随着人们对汽车舒适性,安全性和智能化的要求越来越高,汽车上使用了越来越多的控制单元、传感器及相应的执行器。为了使各个控制单元之间能够进行通讯,共享一些信号,同时避免造连接这些电气电子元件的导线占用车上更多的空间,增加汽车本身的重量,降低汽车成本,汽车上越来越多的使用了总线系统,其中CAN总线是使用最广泛的一种。在汽车检测维修过程中,很多维修人员认为CAN总线很复杂,一旦出现故障,很多人望而却步,本文是对CAN总线系统检测实践教学中一点经验的总结,仅供参考。

With the increasing demand for vehicle comfort, safety and intelligence, more and more control units and corresponding sensors and actuators are used on cars. In order to enable all communication between control units, sharing some signal, at the same time avoid the wire connecting these electrical electronic components occupy more space on the car, and increases the car＇s weight, reduce the cost of the cars, more and more cars are increasingly using the bus system, CAN bus is one of the most widely used. In the process of vehicle inspection and maintenance, many maintenance personnel think that CAN bus is very complex. Once a failure occurs, many people are deterred. This article is a summary of experience in CAN bus system testing practice teaching, for reference only.
