车辆事件数据接口-车辆数据提取

[中文适用范围]： 本推荐实践旨在定义一种通用方法，用于确定如何从机动车辆中提取事件数据，包括输出 SAE J 1698 中定义的数据元素的事件记录所需的事件数据集。它旨在供开发人员使用用于事件数据集提取的工具。本建议实践旨在利用现有的行业标准来定义事件数据集提取所需的通用物理接口和协议。为了实现这一目标，SAE J 1962 诊断连接器被设计为主要物理接口，并且指定了用于通信的相关行业标准诊断协议。 [外文原描述]： This SAE Recommended Practice utilizes existing industry StandardDetails to identify a common physical interface and define the protocols necessary to retrieve records stored by light duty vehicle event data recorders (EDRs). To accomplish this, the SAE J1962 diagnostic connector is designated as the primary physical interface for EDR retrieval tools.This SAE Recommended Practice is intended to be used for the development of EDR retrieval tools. Retrieval tools are intended to interface with light duty vehicles and to produce EDR record reports with data element formats specified by SAE J1698-1.Limitations:This SAE Recommend Practice specifies how EDR records should be imaged, translated, and reported by EDR retrieval tools. It does not specify how EDR records are recorded and stored by individual vehicles.This SAE Recommended Practice addresses EDR record retrieval (including imaging and translating) via the connection to the vehicle’s SAE J1962 connector or via direct connection to an electronic control unit (ECU) containing an EDR record. Direct connection to an ECU may require the use of specialized interface adapters.Cross Reference:
