标准摘要
[中文适用范围]: 本部分的ISO 27145定义了ISO 27145系列的所有规范数据元素。数据元素用于向外部测试设备提供车辆车载诊断(VOBD)系统诊断状态。所有数据元素均通过ISO 27145-3中定义的统一诊断服务进行通信。数据元素包括故障检测代码(DTC)、数据标识符(DID)和例程标识符(RID)。本部分描述了参数标识符(PID)、监视器标识符(MID)和信息类型标识符(ITID)的映射关系。如果建立了新的规范整车排放-OBD GTR模块,则希望ISO 27145能够适用并可能进行扩展,这些扩展可以包含在本部分中、作为SAE数字附录的增强功能或甚至成为其他参考文件的一部分,这些文件旨在包含适用的数据定义。ISO 27145旨在成为访问与OBD相关的信息(VOBD)的唯一通信标准。为使现有通信标准顺利迁移到未来的全球统一通信标准,本部分中ISO 27145-4规定的通信概念基于两条不同的数据链路:ISO 15765-4和ISO 13400(所有部分)。考虑到使用标准网络层协议,未来可以扩展到可选的物理层(例如无线)。注意:根据引入的其他通信介质,可能会对ISO 27145-4进行必要的扩展。ISO 27145-4是与车辆建立通信的入口点。根据初始化结果,外部测试设备确定车辆排放相关系统支持哪些协议和诊断服务,即:– 法规性OBD:ISO 15031系列,和 – 法规性WWH-OBD:ISO 27145。根据ISO 27145的车辆提供VOBD系统支持,符合全球技术法规(GTR)第5号中对WWH-OBD的设想。注意:本部分不包括源自将GTR No. 5引入地方立法的国家特定实施所产生的用例。 [外文原描述]: ISO 27145-2:2012 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 ISO 27145-2:2012. 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 ISO 27145-2:2012, 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. 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).
