摘　　要：介绍了基于CAN的车载故障诊断标准ISO15765的体系结构,分析了ISO15765网络层中为上层提供服务和内部操作的机制与特征,给出了ISO15765在多帧传送方式下流控制管理机制和时间管理机制的实现方法。为完成ISO15765的软件开发,从数据拆分模块和数据重组模块的实现、流控制管理的实现、时间管理和错误处理模块的实现4个方面讨论了网络层软件的设计思想。测试结果表明,所给出的ISO15765网络层实现方法是可行的。In this paper,the architecture of automotive fault diagnostic standard ISO15765 based on CAN is introduced,and the mechanism and characteristic of the services provided by the network layer to higher layer and internal operations are analyzed,with the method to implement the flow control mechanism and time mechanism of ISO15765 in multiple frame transmission.In order to realize the software development of ISO15765,the design idea of the network layer software is discussed from 4 aspects such as implementations of the segmentation and re-assembly module,the flow control mechanism,time management mechanism and errors handling module.The results of the experiment show the methods are feasible.
