标准范围
ISO 22901-1:20 08规定了使用新的行业标准诊断格式来使诊断工具应用制造商可以获得诊断数据流信息的概念,以便简化对汽车售后服务行业的支持。开放诊断数据交换(ODX)建模的诊断数据与模块化车辆通信接口(MVCI)的软件要求兼容,如ISO 22900-2和ISO 22900-3中规定的。ODX建模的诊断数据将使MVCI设备能够与车辆电子控制单元(ECU)通信,并解释包含在外部测试设备和ECU之间交换的消息中的诊断数据。对于符合ODX的外部测试设备,无需进行软件编程即可将诊断数据转换为技术人员可读信息,由测试仪显示。ODX规范包含描述车辆和物理ECU的所有诊断数据的数据模型,例如诊断故障代码、数据参数、识别数据、输入/输出参数、ECU配置(变体编码)数据和通信参数。ODX用统一建模语言(UML)图描述,数据交换格式使用可扩展标记语言(XML)。ODX建模诊断数据描述:ECU诊断通信协议规范;不同协议和数据链路层以及ECU软件的通信参数;ECU编程数据(闪存);相关车辆接口描述(连接器和引脚排列);ECU网络的诊断能力的功能描述;ECU配置数据(变体编码)。ISO 22901-1:20 08的目的是确保来自任何车辆制造商的诊断数据独立于任何测试设备制造商提供的测试硬件和协议软件。
ISO 22901-1:2008 specifies the concept of using a new industry standard diagnostic format to make diagnostic data stream information available to diagnostic tool application manufacturers, in order to simplify the support of the aftermarket automotive service industry. The Open Diagnostic Data Exchange (ODX) modelled diagnostic data are compatible with the software requirements of the Modular Vehicle Communication Interface (MVCI), as specified in ISO 22900-2 and ISO 22900-3. The ODX modelled diagnostic data will enable an MVCI device to communicate with the vehicle Electronic Control Unit(s) (ECU) and interpret the diagnostic data contained in the messages exchanged between the external test equipment and the ECU(s). For ODX compliant external test equipment, no software programming is necessary to convert diagnostic data into technician readable information to be displayed by the tester.The ODX specification contains the data model to describe all diagnostic data of a vehicle and physical ECU, e.g. diagnostic trouble codes, data parameters, identification data, input/output parameters, ECU configuration (variant coding) data and communication parameters. ODX is described in Unified Modelling Language (UML) diagrams and the data exchange format uses Extensible Mark-up Language (XML).The ODX modelled diagnostic data describe:
- protocol specification for diagnostic communication of ECUs;
- communication parameters for different protocols and data link layers and for ECU software;
- ECU programming data (Flash);
- related vehicle interface description (connectors and pinout);
- functional description of diagnostic capabilities of a network of ECUs;
- ECU configuration data (variant coding).
