道路车辆.全球调和车载诊断系统(WWH-OBD)通信要求实施.第1部分:通用信息和使用案例定义

[中文适用范围]： ISO 27145 的这一部分概述了不同部分的结构和划分，以便从现有通信标准平滑迁移到未来的全球通信标准，最初的通信概念基于 ISO 15765 系列，即通过控制局域网 (DoCAN) 进行诊断通信。 其目的是使未来的通信概念基于 ISO 13400 系列，即利用以太网通过互联网协议 (DoIP) 进行诊断通信。 鉴于标准网络层协议的使用，未来对可选物理层（例如无线）的扩展是可能的。 标准。 根据初始化的结果，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 系列（基于 DoCAN），以及 — 法定 WWH-OBD：ISO 27145系列（基于DoCAN和DoIP）。 [外文原描述]： This part of ISO 27145 provides an overview of the structure and the partitioning 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 communication 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 Network (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. wireless) 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 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).
