17、es). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a subject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and

18、non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are desc

19、ribed in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. This document was drafted in accordance with the editorial rules of the ISO/IEC Directives, Part 2 (see www.iso.org/directives). Attention is drawn

20、to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of any patent rights identified during the development of the document will be in the Introduction and/or on the

26、 data interchange between a commercial vehicle and its towed vehicle(s), including communication between towed vehicles, using a Controller Area Network (CAN) data link according to ISO 11992-1 and based on the definitions for unified diagnostic services and their implementation on CAN given in the

27、ISO 14229 and ISO 15765 document series.To achieve this, the document is based on the Open Systems Interconnection (OSI) Basic Reference Model, in accordance with ISO/IEC 7498-1 and ISO/IEC 10731, which structures the communication systems into seven layers. When mapped on this model, the services u

28、sed by a diagnostic tester (client) and an Electronic Control Unit (ECU, server) based on this document are broken into the following layers according to Table 1: application layer (layer 7), based on ISO 11992-4, ISO 14229-1, and ISO 14229-3; presentation layer (layer 6), vehicle manufacturer/syste

29、m supplier specific or ISO 22901, ODX; session layer services (layer 5), based on ISO 11992-4 and ISO 14229-2; transport layer services (layer 4), based on ISO 11992-4 and ISO 15765-2; network layer services (layer 3), based on ISO 11992-4 and ISO 15765-2; data link layer (layer 2), specified in ISO

30、 11898-1; physical layer (layer 1), specified in ISO 11992-1.This document does not include any redundant information of the documents listed in this introduction. It focuses on additional requirements specific to the implementation of UDS on an ISO 11992 network and specific restrictions in the imp

31、lementation of UDS on an ISO 11992 network.In case of any contradictions, the definitions given in this document take precedence.Table 1 International Standards applicable to the OSI layersApplicability OSI seven layers Diagnostics services on the communication between the com-mercial vehicles and t

36、r (client) to control diagnostic functions in an on-vehicle ECU (server) embedded in a road vehicle using the communication gateways between the vehicles.It defines the data link layers specific implementation of the unified diagnostic communication requirements, mainly given in the ISO 14229 and IS
