This part of ISO 27145 defines all regulatory data elements of the ISO 27145 series. The data elements are
used to provide the external test equipment with the diagnostic status of the vehicle on-board diagnostics
(VOBD) system in the vehicle. All data elements are communicated with the unified diagnostic services as
defined in ISO 27145-3. The data elements are diagnostic trouble codes (DTCs), data identifiers (DIDs) and
routine identifiers (RIDs). The mapping from parameter identifiers (PIDs), monitor identifiers (MIDs) and info
type identifiers (ITIDs) is described in this part of ISO 27145.
ISO 27145的这一部分定义了ISO 27145系列的所有管理数据元素。数据元素用于为外部测试设备提供车辆车载
诊断 (VOBD) 系统的诊断状态。所有数据元素都与ISO 27145-3中定义的统一诊断服务通信。数据元素是诊断故
障代码 (DTCs)、数据标识符 (DIDs) 和常规标识符 (RIDs)。来自参数标识符 (PIDs)、监视器标识符 (MIDs) 和信
息类型标识符 (ITIDs) 的映射在 ISO 27145 的这一部分中描述。
If new legislated WWH-OBD GTR modules are established, it is intended that ISO 27145 be applicable with
possible extensions, which can be included in this part of ISO 27145, can be specified as enhancements of
the SAE Digital Annexes or can even be part of other referenced documents which are intended to include the
applicable data definitions.
如果建立了新的立法 WWH-OBD GTR 模块, 它的目的是ISO 27145适用于可能的扩展, 可以包括在ISO 27145
的这一部分, 可以指定为增强 SAE 数字附件或甚至可以是其他的一部分用于包含适用的数据定义的引用文档。
ISO 27145 is intended to become the single communication standard for access to OBD-related information
(VOBD). To allow for a smooth migration from the existing communication standards to this future world-wide
communication standard, the communication concept as specified in ISO 27145-4 is based on two different
data links: ISO 15765-4 and ISO 13400 (all parts).
ISO 27145 旨在成为获得与 VOBD 相关信息的单一通信标准。为了允许从现有通信标准顺利迁移到这个未来的
全球通信标准, ISO 27145-4 中指定的通信概念基于两个不同的数据链接: ISO 15765-4 和ISO 13400 (所有部分)。
In view of the usage of standard network layer protocols, future extensions to optional physical layers (e.g.
wireless) are possible.
鉴于标准网络层协议的使用, 将来可以扩展到可选物理层 (例如无线)。
NOTE It is expected to extend ISO 27145-4 as necessary upon introduction of additional communication media.
注意 在引入额外的通信媒体时, 预计在必要时将 ISO 27145-4 扩展。
ISO 27145-4 is the entry point to establish communication with the vehicle. Based on the results of the
initialization, the external test equipment determines which protocol and diagnostic services are supported by
the vehicle's emissions-related system, i.e.
ISO 27145-4 是与车辆建立通信的切入点。根据初始化的结果, 外部测试设备确定了车辆与排放有关的系统支持
哪些协议和诊断服务, 即:
legislated OBD: ISO 15031 series, and 法定OBD: ISO 15031 系列, 以及
legislated WWH-OBD: ISO 27145. 法定WWH-OBD:ISO 27145
Vehicles according to ISO 27145 provide VOBD system support as envisioned for WWH-OBD by Global
Technical Regulation (GTR) No. 5.
根据 ISO 27145 的车辆提供 VOBD 系统支持, WWH-OBD 全球技术法规 (GTR) 5 号的设想。
IMPORTANT — Use cases deriving from country-specific implementation of GTR No. 5 into local
legislation are not included in this part of ISO 27145.
重点——在 ISO 27145 的这一部分中不包括从国家具体执行GTR No.5号标准到地方立法的重要用例。
