It is the UK implementatio
3、n of ISO/PAS 27145-1:2006. This publication is not to be regarded as a British Standard. It is being issued in the Draft for Development series of publications and is of a provisional nature. It should be applied on this provisional basis, so that information and experience of its practical applicat
4、ion can be obtained. A PAS is a Technical Specification not fulfilling the requirements for a standard, but made available to the public and established in an organization operating under a given procedure. A review of this Draft for Development will be carried out not later than 3 years after its p
5、ublication. Notification of the start of the review period, with a request for the submission of comments from users of this Draft for Development, will be made in an announcement in the appropriate issue of Update Standards. According to the replies received, the responsible BSI Committee will judg
6、e whether the validity of the PAS should be extended for a further three years or what other action should be taken and pass their comments on to the relevant international committee. Observations which it is felt should receive attention before the official call for comments will be welcomed. These
7、 should be sent to the Secretary of the responsible BSI Technical Committee at British Standards House, 389 Chiswick High Road, London W4 4AL. The UK participation in its preparation was entrusted to Technical Committee AUE/16, Electrical and electronic equipment. A list of organizations represented

15、 bodies (ISO member bodies). 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 organiza
16、tions, governmental and 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. International Standards are drafted in accordance with the rules given in t
17、he ISO/IEC Directives, Part 2. The main task of 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
18、 the member bodies casting a vote. In other circumstances, particularly when there is an urgent market requirement for such documents, a technical committee may decide to publish other types of normative document: an ISO Publicly Available Specification (ISO/PAS) represents an agreement between tech
19、nical experts in an ISO working group and is accepted for publication if it is approved by more than 50 % of the members of the parent committee casting a vote; an ISO Technical Specification (ISO/TS) represents an agreement between the members of a technical committee and is accepted for publicatio
20、n if it is approved by 2/3 of the members of the committee casting a vote. An ISO/PAS or ISO/TS is reviewed after three years in order to decide whether it will be confirmed for a further three years, revised to become an International Standard, or withdrawn. If the ISO/PAS or ISO/TS is confirmed, i
21、t is reviewed again after a further three years, at which time it must either be transformed into an International Standard or be withdrawn. Attention is 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 ide
22、ntifying any or all such patent rights. ISO/PAS 27145-1 was prepared by Technical Committee ISO/TC 22, Road vehicles, Subcommittee SC 3, Electrical and electronic equipment. ISO/PAS 27145 consists of the following parts, under the general title Road vehicles Implementation of WWH-OBD communication r

25、 vehicles within the scope of the WWH-OBD GTR (World Wide Harmonized On-Board Diagnostics Global Technical Regulations). It has been established in order to apply the unified diagnostic services (specified in ISO 14229-1). To achieve this, it is based on the Open Systems Interconnection (OSI) Basic
26、Reference Model in accordance with ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers. When mapped on this model, the services specified by ISO/PAS 27145 are broken into: Diagnostic services (layer 7), specified in ISO/PAS 27145-3; Presentation layer (layer 6)
27、, specified in ISO/PAS 27145-2; Session layer services (layer 5), specified in ISO/PAS 27145-4; Transport layer services (layer 4), specified in ISO/PAS 27145-4; Network layer services (layer 3), specified in ISO/PAS 27145-4; Data link layer (layer 2), specified in ISO/PAS 27145-4; Physical layer (l
28、ayer 1), specified in ISO/PAS 27145-4; in accordance with Table 1.

31、s Part 1: General information and use case definition 1 Scope ISO/PAS 27145 is intended to become the single communication standard for access to OBD-related information. To allow for a smooth migration from the existing communication standards to this future worldwide standardized communication sta
32、ndard, the initial communication concept will be based on CAN. In a second step, ISO/PAS 27145 will be extended to define the world-wide harmonized OBD communication standard based on existing industry communications standards (e.g. Internet Protocol) over Ethernet. Due to the usage of standard netw
33、ork layer protocols, future extensions to optional physical layers (e.g. wireless) are possible. This part of ISO/PAS 27145 gives an overview of the structure and the partitioning of the different parts of this standard, and shows the relation between the parts. In addition, it outlines the use case
34、 scenarios where the ISO/PAS 27145 document set will be used. All terminology that is common throughout the ISO/PAS 27145 document set is also outlined here. 2 Normative references The following referenced documents are indispensable for the application of this document.
