道路车辆.开放式诊断数据交换（ODX）.第3部分：故障症状交换描述（FXD）

[中文适用范围]： 本文件规定了所有故障症状算法的机器可读描述，这些算法作为电子控制单元 (ECU) 中的诊断软件实施。主要用例是从功能和软件供应商到车辆制造商 (VM) 的标准化数据交换，以实现基于工具的信息处理。基于 FXD 内容和相关校准值，可以生成多个最终用户文档，例如作为车辆类型批准文档包的一部分所需的“摘要表”或“维修和维护信息”(RMI)。FXD 方法的预期主要好处是整体效率提高以及独立于供应商和 VM 特定的格式处理。 [外文原描述]： ISO 22901-3:2018 specifies machine-readable descriptions of all fault symptom algorithms which are implemented as diagnostic software in an electronic control unit (ECU). The main use case is the standardized data exchange from a function & software supplier to a vehicle manufacturer (VM) in order to enable a tool-based information processing. Based on the FXD content and associated calibration values, several end user documents can be generated such as the "summary sheet" needed as part of the vehicle type approval documentation package or the "repair and maintenance information" (RMI). The expected main benefits of the FXD approach are an overall efficiency improvement as well as an independency of supplier- and VM-specific format handling.
