The work of prepari
24、ng 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 non-governmental, in lia
25、ison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization. International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2. The main task of
26、technical committees is to prepare International Standards. Draft International Standards adopted by the technical committees are circulated to the member bodies for voting. Publication as an International Standard requires approval by at least 75 % of the member bodies casting a vote. Attention is
27、drawn 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. ISO 22900-2 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electr
28、onic equipment. ISO 22900 consists of the following parts, under the general title Road vehicles Modular vehicle communication interface (MVCI): Part 1: Hardware design requirements Part 2: Diagnostic protocol data unit application programming interface (D-PDU API) Part 3: Diagnostic server applicat
29、ion programming interface (D-Server API) ISO 22900-2:2009(E) ISO 2009 All rights reserved viiIntroduction ISO 22900 is applicable to vehicle electronic control module diagnostics and programming. This part of ISO 22900 was established in order to more easily exchange software and hardware of vehicle
30、 communication interfaces (VCIs) among diagnostic applications. It defines a generic and protocol independent software interface towards the modular vehicle communication interface (MVCI) protocol module, such that a diagnostic application based on this software interface can exchange the MVCI proto
31、col module or add a new MVCI protocol module with minimal effort. Today, the automotive after market requires flexible usage of different protocol modules for vehicles of different brands. Many of todays protocol modules are incompatible with regard to their hardware and software interface, such tha
32、t, depending on the brand, a different protocol module is required. The objective of this part of ISO 22900 is to specify the diagnostic protocol data unit application programming interface (D-PDU API) as a generic software interface, and to provide a “plug and play” concept for access onto differen
33、t MVCI protocol modules from different tool manufacturers. The D-PDU API will address the generic software interface, the protocol abstraction, its exchangeability as well as the compatibility towards existing standards such as SAE J2534-1 and RP1210a. The implementation of the modular VCI concept f
34、acilitates co-existence and re-use of MVCI protocol modules, especially in the after market. As a result, diagnostic or programming applications can be adapted for different vehicle communication interfaces and different vehicles with minimal effort, thus helping to reduce overall costs for the tool
35、 manufacturer and end user. Vehicle communication interfaces compliant with ISO 22900 support a protocol-independent D-PDU API as specified in this part of ISO 22900.

36、 Part 2: Diagnostic protocol data unit application programming interface (D-PDU API) 1 Scope This part of ISO 22900 specifies the diagnostic protocol data unit application programming interface (D-PDU API) as a modular vehicle communication interface (MVCI) protocol module software interface and com
37、mon basis for diagnostic and reprogramming software applications. This part of ISO 22900 covers the descriptions of the application programming interface (API) functions and the abstraction of diagnostic protocols, as well as the handling and description of MVCI protocol module features. Sample MVCI
38、 module description files accompany this part of ISO 22900. Migration from and to the existing standards SAE J2534-1 and RP1210a is addressed. This part of ISO 22900 contains a description of how to convert between the APIs. Corresponding wrapper APIs accompany this part of ISO 22900. The purpose of
39、 this part of ISO 22900 is to ensure that diagnostic and reprogramming applications from any vehicle or tool manufacturer can operate on a common software interface, and can easily exchange MVCI protocol module implementations. 2 Normative references The following referenced documents are indispensa

44、PDU API) NOTE From the perspective of the D-PDU API, it does not make any difference whether an application accesses the software interface directly, or through an MVCI D-Server. Consequently, in this part of ISO 22900, the term “application” represents both ways of accessing the D-PDU API. 3.2 ComL
