16、4:2016(E)ForewordISO (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 subject for w

17、hich 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 (IEC) on all

18、 matters of electrotechnical standardization.The procedures used to develop this document and those intended for its further maintenance are described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the different types of ISO documents should be noted. Thi

25、stics Global Technical Regulations (WWH-OBD GTR).It has been established in order to apply the unified diagnostic services (specified in ISO 14229-1) to WWH-OBD systems.The ISO 27145 series includes the communication between the vehicles WWH-OBD systems and external (off-board) “generic” test equipm

26、ent within the scope of the country-specific regulatory requirements.To achieve this, it is based on the Open Systems Interconnection (OSI) Basic Reference Model specified in ISO/IEC 7498-1 and ISO/IEC 10731, which structures communication systems into seven layers. When mapped on this model, the se

37、 revision procedureNew regulatory requirements drive new in-vehicle technology to lower emissions, improve safety, etc. It is important to standardize new technology-related OBD monitor data and DTCs in order to support the external (off-board) “generic” test equipment. All relevant information is p

38、roposed by the automotive industry, represented by members of the appropriate SAE task force.ISO 27145-2 references a “change request form” for use with new data items to be defined by the SAE task force for standardization. It is intended that the standardized data items be defined in SAE J1930-DA,

39、 SAE J1979-DA, SAE J2012-DA and SAE J1939. It is intended that the documents be published on the SAE store website once the information has been balloted and approved.

45、cs (WWH-OBD) communication requirements Part 4: Connection between vehicle and test equipment1 ScopeThis part of ISO 27145 defines the requirements to successfully establish, maintain and terminate communication with a vehicle that implements the requirements of the WWH-OBD GTR (Global technical reg

46、ulation No. 5; see Reference 16). This requires plug and play communication capabilities for the vehicle, as well as for any test equipment that intends to establish communication with a vehicle. This part of ISO 27145 details all the OSI layer requirements to achieve this goal.This part of ISO 2714

47、5 is intended to become the single communication standard for access to information relating to vehicle on-board diagnostics (VOBD). To allow for a smooth migration from the existing communication standards to this future world-wide standardized communication standard, the communication concept as s

48、pecified in this part of ISO 27145 is based on two different data links: diagnostic communication over Controller Area Network (DoCAN), ISO 15765-4; diagnostic communication over Internet Protocol (DoIP), ISO 13400 (all parts).NOTE It is intended that this part of ISO 27145 will be extended as neces

49、sary upon introduction of additional communication media.IMPORTANT Use cases deriving from country-specific implementation of GTR No. 5 into local legislation are not included in this part of ISO 27145.2 Normative referencesThe following documents, in whole or in part, are normatively referenced in this document and are indispensable for its application.
