本SAE推荐实施规程利用现有行业标准来确定通用物理接口，并定义检索轻型车辆事件数据记录器（EDR）存储的记录所需的协议。为了实现这一点，SAE J1962诊断连接器被指定为EDR检索工具的主要物理接口。本SAE推荐实施规程旨在用于开发EDR检索刀具。检索工具旨在与轻型车辆对接，并使用SAE J1698规定的数据元素格式生成EDR记录报告- 1.限制:本SAE推荐规程规定了EDR检索工具应如何对EDR记录进行成像、翻译和报告。它没有规定EDR记录是如何由单个车辆记录和存储的。本SAE推荐实施规程通过连接到车辆的SAE J1962连接器或通过直接连接到包含EDR记录的电子控制单元（ECU）来处理EDR记录检索（包括成像和翻译）。直接连接到ECU可能需要使用专用接口适配器。

This SAE Recommended Practice utilizes existing industry standards 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.
