19、 Harmonized On-Board Diagnostics 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-b

41、ning of the different parts of ISO 27145 and shows the relationship between the parts. In addition, it outlines the use case scenarios where the ISO 27145 series is used. All terminology that is common throughout the ISO 27145 series is also outlined.ISO 27145 is intended to become the single commun
42、ication standard for access to OBD-related information. To allow for a smooth migration from the existing communication standards to this future world-wide communication standard, the initial communication concept is based on the ISO 15765 series, i.e. Diagnostic communication over Control Area Netw
43、ork (DoCAN).The intention is for the future communication concept to be based on the ISO 13400 series, i.e. Diagnostic communication over Internet Protocol (DoIP) utilizing Ethernet. In view of the usage of standard network layer protocols, future extensions to optional physical layers (e.g. wireles
44、s) are possible.ISO 27145 has been extended to define the world-wide harmonized On-Board Diagnostics (OBD) communication standard. Based on the results of the initialization, the external test equipment determines which protocol and diagnostic services are supported by the vehicles emissions-related
45、 system, i.e. legislated OBD: ISO 15031 series (based on DoCAN), and legislated WWH-OBD: ISO 27145 series (based on DoCAN and DoIP).IMPORTANT Use cases deriving from country-specific implementation of Global Technical Regulation (GTR) No. 5 into local legislation are not included in this part of ISO
