标准范围

ISO 15765-4:20 11规定了控制器局域网（CAN）的要求，其中一个或多个控制器符合车载诊断（OBD）或全球统一车载诊断（WWH-OBD）法规。网络假定使用外部测试设备进行检查和维修诊断，如法规所定义的。车辆和外部测试设备的CAN网络要求基于ISO 15765-2、ISO 11898-1和ISO 11898-2的规范。ISO 15765-4:20 11对这些国际标准进行了限制，以满足法规的要求。它没有指定车载CAN总线架构，但试图确保车辆的受监管CAN通信符合外部测试设备要求。ISO 15765-4:20 11定义了与符合OBD/WWH-要求的车辆成功建立、保持和终止通信的要求。OBD法规。定义了车辆和测试设备之间的即插即用通信能力，以确保外部测试设备和车辆的互操作。ISO 15765-4:20 11详细说明了实现这一目标的所有OSI层要求。ISO 15765-4:20 11是DoCAN（CAN上的诊断通信）的切入点。基于初始化的结果，外部测试设备确定车辆的排放相关系统支持哪些协议和诊断服务:法定OBD:ISO 15031（所有部件），法定WWH-OBD:ISO 27145（所有部分）。

ISO 15765-4:2011 specifies requirements for controller area networks (CAN) where one or more controllers comply with on-board diagnostics (OBD) or world-wide harmonized on-board diagnostics (WWH-OBD) regulations. The network presumes the use of an external test equipment for inspection and repair diagnostics, as defined by the regulations. The CAN network requirements for the vehicle and the external test equipment are based on the specifications of ISO 15765-2, ISO 11898-1 and ISO 11898-2.ISO 15765-4:2011 places restrictions on those International Standards for the fulfilment of the regulations. It does not specify in-vehicle CAN bus architecture, but seeks to ensure that the vehicle's regulated CAN communications comply with external test equipment requirements.ISO 15765-4:2011 defines the requirements to successfully establish, maintain and terminate communication with a vehicle that implements the requirements of the OBD/WWH-OBD regulations. Plug-and-play communication capabilities among vehicles and test equipment are defined to assure the interoperation of external test equipment and vehicles. ISO 15765-4:2011 details all of the OSI layer requirements to achieve this goal.ISO 15765-4:2011 is the entry point for DoCAN (Diagnostic communication over CAN). Based on the results of the initialization, the external test equipment determines which protocol and diagnostic services are supported by the vehicle's emissions-related system:

• legislated OBD: ISO 15031 (all parts),
• legislated WWH-OBD: ISO 27145 (all parts).
