16、l rights reserved vForeword ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies (ISO member bodies). The work of preparing International Standards is normally carried out through ISO technical committees. Each member body interested in a su

17、bject for which a technical committee has been established has the right to be represented on that committee. International organizations, governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the International Electrotechnical Commission (

18、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 technical committees is to prepare International Standards. Draft International Standards adopted by the technical commi

19、ttees 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 drawn to the possibility that some of the elements of this document may be the subject of patent rights. ISO shall not b

20、e held responsible for identifying any or all such patent rights. ISO 22901-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. ISO 22901 consists of the following parts, under the general title Road vehicles Open diagnostic data ex

21、change (ODX): Part 1: Data model specification The following parts are under preparation: Part 2: Emissions-related diagnostic dataBS ISO 22901-1:2008ISO 22901-1:2008(E) vi ISO 2008 All rights reservedIntroduction The purpose of this part of ISO 22901 is to define the data format for transferring El

22、ectronic Control Unit (ECU) diagnostic and programming data between the system supplier, vehicle manufacturer and service dealerships and diagnostic tools of different vendors. In todays automotive industry, an informal description is generally used to document the diagnostic data stream information

23、 of vehicle ECUs. Any user wishing to use the ECU diagnostic data stream documentation to set up development tools or service diagnostic test equipment needs a manual transformation of this documentation into a format readable by these tools. This effort will no longer be required if the diagnostic

24、data stream information is provided in Open Diagnostic Data Exchange (ODX) format and if those tools support the ODX format. This part of ISO 22901 includes the data model definition of ECU diagnostic and programming data and the related vehicle interface description in Unified Modelling Language (U

25、ML). This part of ISO 22901 also includes an implementation by Extensible Mark-up Language (XML) schema in Annex C. BS ISO 22901-1:2008INTERNATIONAL STANDARD ISO 22901-1:2008(E) ISO 2008 All rights reserved 1Road vehicles Open diagnostic data exchange (ODX) Part 1: Data model specification 1 Scope T

26、his part of ISO 22901 specifies the concept of using a new industry standard diagnostic format to make diagnostic data stream information available to diagnostic tool application manufacturers, in order to simplify the support of the aftermarket automotive service industry. The Open Diagnostic Data

27、Exchange (ODX) modelled diagnostic data are compatible with the software requirements of the Modular Vehicle Communication Interface (MVCI), as specified in ISO 22900-2 and ISO 22900-3. The ODX modelled diagnostic data will enable an MVCI device to communicate with the vehicle Electronic Control Uni

28、t(s) (ECU) and interpret the diagnostic data contained in the messages exchanged between the external test equipment and the ECU(s). For ODX compliant external test equipment, no software programming is necessary to convert diagnostic data into technician readable information to be displayed by the

29、tester. The ODX specification contains the data model to describe all diagnostic data of a vehicle and physical ECU, e.g. diagnostic trouble codes, data parameters, identification data, input/output parameters, ECU configuration (variant coding) data and communication parameters. ODX is described in

30、 Unified Modelling Language (UML) diagrams and the data exchange format uses Extensible Mark-up Language (XML). The ODX modelled diagnostic data describe: protocol specification for diagnostic communication of ECUs; communication parameters for different protocols and data link layers and for ECU so

31、ftware; ECU programming data (Flash); related vehicle interface description (connectors and pinout); functional description of diagnostic capabilities of a network of ECUs; ECU configuration data (variant coding). Figure 1 shows the usage of ODX in the ECU life cycle. The purpose of this part of ISO

32、 22901 is to ensure that diagnostic data from any vehicle manufacturer is independent of the testing hardware and protocol software supplied by any test equipment manufacturer. 2 Normative references The following referenced documents are indispensable for the application of this document.

39、l Figure 1 Usage of ODX data in the ECU life cycle shows the usage of ODX in the ECU life cycle. Engineering, manufacturing, and service specify communication protocol and data to be implemented in the ECU. This information will be documented in a structured format utilizing the XML standard and by

40、an appropriate ODX authoring tool. There is potential to generate ECU software from the ODX file. Furthermore, the same ODX file is used to setup the diagnostic engineering tools to verify proper communication with the ECU and to perform functional verification and compliance testing. Once all quali

41、ty goals are met, the ODX file may be released to a diagnostic database. Diagnostic information is now available to manufacturing, service, OEM franchised dealers, and aftermarket service outlets via Intranet and Internet. Figure 1 Usage of ODX data in the ECU life cycle 4.2 Use case 1: ODX process

42、chain Figure 2 shows an example of how ODX data is used in a process chain consisting of three phases, as described below. a) Phase A of the development process between vehicle manufacturer and system supplier comprises the exchange of ODX data to support the development of the diagnostic implementa

43、tion in the ECU and the development tools. b) In phase B of the development process at the vehicle manufacturer, the engineering departments release the ODX data into a diagnostic database. The manufacturing and service departments use the ODX data as the basis to setup the End-Of-Line test equipmen

44、t and service application development tools and generate service documentation. c) Phase C of the development process supports the service dealership diagnostic and programming tools. The service department develops service tool application software based on the ODX data model. The diagnostic and pr

45、ogramming software is now available to all service dealerships.

46、ic development A vehicle manufacturer implements electronic systems into multiple new vehicle platforms. There is little variation in the electronic system across the different vehicle platforms. Utilizing the same ECU in many different vehicle platforms reduces redundant development effort. The maj

47、ority of design, normal operation, and diagnostic data of an electronic system can be reused in various vehicles. Large automotive manufacturer tend to have multiple engineering development centres. Diagnostic data exchange can be based on the ODX data format to reduce the amount of proofreading of

48、diagnostic data at different development sites. Establishing an ODX compliant tool chain will avoid re-authoring diagnostic data into various specific formats at different engineering sites.
