道路车辆.电子定期技术检查（ePTI）用车辆接口.第1部分：应用和通信要求

[中文适用范围]： 本文件适用于道路车辆，其中电子车辆接口用于执行属于定期技术检查（ePTI）一部分的测试方法。 本文件描述了用例并指定了技术要求，以便在通过电子接口进行定期技术检查期间支持 ePTI 相关车辆安全系统检查。 本文档引用了 ISO 14229 系列、在控制器局域网 (DoCAN) 和互联网协议 (DoIP) 上的诊断通信上实现的统一诊断服务以及所需的数据定义规定。 排放相关系统的诊断服务和数据定义的技术要求在其他国际标准中规定，例如ISO 15031和ISO 27145。 将来可以考虑其他环境系统的ePTI用例和技术要求。 本文件定义： ——描述通过与 ePTI 相关的诊断链路连接器进行车辆通信功能的所有要求，例如： 1) ePTI 数据链路的发现； 2) 发现 ePTI 相关系统； 3) 查询ePTI相关系统的信息，包括软件标识、软件完整性、当前和/或存储值； 4) ePTI相关系统错误信息查询； 5) 激活ePTI相关系统的执行器或例程； ——关于单个车辆通信功能的用例，例如查询识别信息、命令功能测试方法。 本文件不直接指定 PTI 期间 ePTI 相关系统的任何类型的测试方法或通过/失败标准，但提供可能支持 PTI 测试方法的数据。 该文件规定： ——术语； ——ePTI外部测试设备和车辆的ePTI相关系统之间的通信建立； ——ePTI外部测试设备和车辆之间使用基于凭证的身份验证和授权机制； ——防止篡改已定义的 ePTI 方法； 1  — ePTI 相关用例的定义： ——ePTI 外部测试设备发现 ISO 20730-3 中指定的可用数据标识符； ——ePTI外部测试设备查询ePTI相关系统的信息，包括软件编号、软件完整性信息、当前和/或存储值、自检完成状态、系统状态和错误信息（例如DTC和/或DID信息）； ——ePTI外部测试设备激活ePTI相关系统的执行器或例程； ——ePTI相关技术要求的定义； ——ePTI 外部测试设备最低要求。 本文件不包括： ——执行 PTI 检查的过程定义； ——场外数据提供的流程和数据定义； ——标准化的数据交换格式； ——根据车辆制造商规范对车辆安全系统进行验证和验证。 [外文原描述]： This document is applicable to road vehicles, where the electronic vehicle interface is used to perform a test method that is part of a periodic technical inspection (ePTI). This document describes use cases and specifies technical requirements in order to support the ePTI-relevant vehicle safety system(s) checks during the periodic technical inspection via the electronic interface. This document references the ISO 14229 series, the unified diagnostic services implemented on diagnostic communication over controller area network (DoCAN) and the Internet protocol (DoIP) along with the required provision of data definitions. The technical requirements of diagnostic services and data definitions of emissions-related systems are specified in other International Standards, for example, ISO 15031 and ISO 27145. Other environmental systems' ePTI use cases and technical requirements can be considered in the future. This document defines: — all requirements describing the vehicle-communication functionality via the diagnostic link connector related to ePTI, for example: 1) discovery of the ePTI data link; 2) discovery of the ePTI-relevant systems; 3) query of ePTI-relevant systems’ information, including software identification, software integrity, current and/or stored values; 4) query of ePTI-relevant systems’ error information; 5) activation of ePTI-relevant systems’ actuators or routines; — the use cases about the individual vehicle communication functionality, for example, query identification information, command functional test method. This document does not directly specify any type of test method or pass/fail criteria of the ePTI-relevant system during a PTI, but provides data, which may support PTI test methods. The document specifies: — terminology; — communication establishment between the ePTI external test equipment and the vehicle's ePTI-relevant systems; — usage of a credentials-based authentication and authorisation mechanism between the ePTI external test equipment and the vehicle; — protection against tampering of the defined ePTI methods; — definition of ePTI-relevant use cases: — ePTI external test equipment discovers available data identifier as specified in ISO 20730-3; — ePTI external test equipment queries the ePTI-relevant system’s information, including software numbers, software integrity information, current and/or stored values, self-test completion status, system status, and error information (e.g. DTC and/or DID information); — ePTI external test equipment activates the ePTI-relevant system’s actuators or routines; — definition of ePTI-relevant technical requirements; — ePTI external test equipment minimum requirements. This document excludes: — process definitions for performing the PTI check; — process and data definitions for off-board data provision; — standardised data exchange formats; — validation and verification of vehicle safety systems according to vehicle manufacturer specifications.
