标准摘要
[中文适用范围]: ISO 27145的这一部分定义了指定的统一诊断服务(UDS)子集的实现。 统一诊断服务子集源自WWH-OBD GTR(全球技术法规第5号;参见参考文献[17])中规定的要求。 。 ISO 27145 本部分中定义的通用消息集独立于底层传输、网络、数据链路和物理层。 ISO 27145的这一部分没有对车载网络架构指定任何要求。 ISO 27145 的这一部分与 ISO 14229-1 兼容,并包括支持 SAE J1979-DA 和 SAE J2012-DA WWH-OBD 数据集的规定。 ISO 27145 的这一部分旨在与 ISO 27145-4 一起使用,ISO 27145-4 是协议初始化的入口点,基于两个不同的数据链路: ——通过控制器局域网 (DoCAN)、ISO 15765-1、ISO 进行诊断通信15765-2、ISO 15765-4; ——通过互联网协议 (DoIP)、ISO 13400(所有部分)进行诊断通信。 由于使用标准网络层协议,未来对可选物理层(例如无线)的扩展是可能的。 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 - 法定OBD:ISO 15031(所有部分); ——法定 WWH-OBD:ISO 27145(所有部分)。 ISO 27145 的这一部分包括满足多个地区、车辆类型、车型年份和发动机类型的 OBD 法规所需的功能。 对于某些地区来说,这些规定尚未最终确定,预计未来会发生变化。 ISO 27145 的这一部分并不试图解释法规,也不包括所含诊断服务和数据参数对各种车辆应用的适用性。 ISO 27145 本部分的用户旨在验证其每个条款对于特定车辆、发动机、型号年份和地区的适用性。 [外文原描述]: ISO 27145-3:2012 defines the implementation of a subset of unified diagnostic services (UDS) specified in ISO 14229-1. The diagnostic services are used to communicate the diagnostic data defined in ISO 27145-2. The subset of unified diagnostic services derives from the requirements stated in the World-Wide Harmonized On-Board Diagnostic Global Technical Regulations (WWH-OBD GTR). The common message set defined in ISO 27145-3:2012 is independent of the underlying transport, network, data link and physical layer. ISO 27145-3:2012 does not specify any requirements for the in-vehicle network architecture. ISO 27145-3:2012 is compatible with ISO 14229-1 and includes provisions to support the data set of SAE J1979-DA and SAE J2012-DA WWH-OBD. ISO 27145-3:2012 is intended for use with ISO 27145-4, which is the entry point for the protocol initialization and is based on two different data links: · Diagnostic communication over Controller Area Network (DoCAN), ISO 15765‑1, ISO 15765‑2, ISO 15765‑4; · Diagnostic communication over Internet Protocol (DoIP), ISO 13400 (all parts). ISO 27145-3:2012 includes capabilities required to satisfy OBD regulations for multiple regions, vehicle types, model years, and engine types. Those regulations are not yet final for some regions and are expected to change in the future. ISO 27145-3:2012 does not attempt to interpret the regulations and does not include applicability of the included diagnostic services and data parameters for various vehicle applications. It is intended that users of ISO 27145-3:2012 verify the applicability of each of its clauses for a specific vehicle, engine, model year and region.
