标准范围

ISO 27145的这一部分概述了不同部分的结构和分区ISO 27145并显示了零件之间的关系。此外，它还概述了用例场景，其中使用ISO 27145系列。还概述了整个ISO 27145系列中常见的所有术语。ISO 27145旨在成为访问OBD相关信息的单一通信标准。到允许从现有通信标准顺利迁移到这种未来的全球通信标准，最初的通信概念是基于ISO 15765系列，即诊断通信通过控制区域网络（DoCAN）。目的是未来的通信概念基于ISO 13400系列，即诊断利用以太网的互联网协议（DoIP）通信。鉴于标准网络层的使用协议，未来对可选物理层（例如无线）的扩展是可能的。ISO 27145已扩展到定义全球统一的车载诊断(OBD)通信标准的。基于初始化的结果，外部测试设备确定哪个协议和诊断服务由车辆的排放相关系统支持，即。-法定OBD:ISO 15031系列（基于DoCAN），以及-法定WWH-OBD:ISO 27145系列（基于DoCAN和DoIP）。重要-从特定国家实施全球

This part of ISO 27145 provides an overview of the structure and the partitioning of the different parts ofISO 27145 and shows the relationship between the parts. In addition, it outlines the use case scenarios wherethe 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 communication standard for access to OBD-related information. Toallow for a smooth migration from the existing communication standards to this future world-wide communicationstandard, the initial communication concept is based on the ISO 15765 series, i.e. Diagnostic communicationover Control Area Network (DoCAN).The intention is for the future communication concept to be based on the ISO 13400 series, i.e. Diagnosticcommunication over Internet Protocol (DoIP) utilizing Ethernet. In view of the usage of standard network layerprotocols, future extensions to optional physical layers (e.g. wireless) are possible.ISO 27145 has been extended to define the world-wide harmonized On-Board Diagnostics (OBD) communicationstandard. Based on the results of the initialization, the external test equipment determines which protocol anddiagnostic services are supported by the vehicle's emissions-related 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
