| Abstract: | 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. |
