定义	描述
Default Error Tracer 默认错误跟踪器	The Default Error Tracer is merely a support to SW development and integration and is not contained in the production code.The API is defined, but the functionality can be chosen and implemented by the developer according to his specific needs. Default Error Tracer只是对软件开发和集成的支持，不包含在生产代码中。API已定义，但功能可由开发人员根据其特定需求选择和实现。
Diagnostic Event Manager 诊断事件管理器	The Diagnostic Event Manager is a standard AUTOSAR module which is available in the production code and whose functionality is specified in the AUTOSAR project. 诊断事件管理器是一个标准的AUTOSAR模块，可在生产代码中使用，其功能在AUTOSAR项目中指定。
Extended addressing format 扩展寻址格式	A unique CAN identifier is assigned to each combination of N_SA and Mtype.A unique address is filed to each combination of N_TA and N_TAtype in the first data byte of the CAN frame data field.N_PCI and N_Data are filed in the remaining bytes of the CAN frame data field. 为N_SA和Mtype的每个组合分配一个唯一的CAN标识符。CAN帧数据字段的第一个数据字节中的每个N_TA和N_TAtype组合都有一个唯一的地址。N_PCI和N_Data位于CAN帧数据字段的剩余字节中。
Full-duplex 全双工	Point-to-point communication between two nodes is possible in both directions at any one time. 两个节点之间的点对点通信在任何时候都可以在两个方向进行。
Function Inhibition Manager 功能抑制管理器	The Function Inhibition Manager (FIM) stands for the evaluation and assignment of events to the required actions for Software Components (e.g. inhibition of specific “monitoring functions”). The DEM informs and updates the Function Inhibition Manager (FIM) upon changes of the event status in order to stop or release functional entities according to assigned dependencies. An interface to the functional entities is defined and supported by the Mode Manager. The FIM is not part of the DEM. 功能抑制管理器 (FIM) 代表评估和分配事件到软件组件所需的操作（例如，抑制特定的“监控功能”）。DEM 在事件状态发生变化时通知并更新功能抑制管理器 (FIM)，以便根据分配的相关性停止或释放功能实体。功能实体的接口由模式管理器定义和支持。FIM 不是 DEM 的一部分。
Functional addressing 功能寻址	In the transport layer, functional addressing refers to N-SDU, of which parameter N_TAtype (which is an extension to the N_TA parameter [14] used to encode the communication model) has the value functional. This means the N-SDU is used in 1 to n communications. Thus with the CAN protocol, functional addressing will only be supported for Single Frame communication. In terms of application, functional addressing is used by the external (or internal) tester if it does not know the physical address of an ECU that should respond to a service request or if the functionality of the ECU is implemented as a distributed server over several ECUs. When functional addressing is used, the communication is a communication broadcast from the external tester to one or more ECUs (1 to n communication). Use cases are (for example) broadcasting messages, such as “ECUReset” or “CommunicationControl” OBD communication will always be performed as part of functional addressing. 在传输层，功能寻址是指N-SDU，其中参数N_TAtype（这是对用于编码通信模型的N_TA参数 [14] 的扩展）的值为function。 这意味着N-SDU用于1到n次通信。因此，对于CAN协议，功能寻址将仅支持单帧通信。 在应用方面，如果外部（或内部）测试人员不知道应响应服务请求的ECU的物理地址，则使用功能寻址或者如果 ECU 的功能作为分布式服务器在多个ECU上实现。当使用功能寻址时，通信是从外部测试仪到一个或多个ECU的通信广播（1到n通信）。 用例是（例如）广播消息，例如“ECUReset”或“CommunicationControl” OBD通信将始终作为功能寻址的一部分执行。
Half-duplex 半双工	Point-to-point communication between two nodes is only possible in one direction at a time. 两个节点之间的点对点通信一次只能在一个方向上进行。
Mixed addressing format 混合寻址格式	A unique CAN identifier is assigned to each combination of N_SA, N_TA, N_TAtype. N_AE is placed in the first data byte of the CAN frame data field. N_PCI and N_Data are placed in the remaining bytes of the CAN frame data field. 唯一的CAN标识符被分配给N_SA、N_TA、N_TAtype的每个组合。N_AE放置在CAN帧数据字段的第一个数据字节中。N_PCI和N_Data放置在CAN帧数据字段的剩余字节中。
Multiple connection 多重连接	The CAN Transport Layer should manage several transport protocol communication sessions at a time. CAN 传输层应一次管理多个传输协议通信会话。
Normal addressing format 正常寻址格式	A unique CAN identifier is assigned to each combination of N_SA, N_TA, N_TAtype and Mtype. N_PCI and N_Data are filed in the CAN frame data field. 唯一的CAN标识符被分配给N_SA、N_TA、N_TAtype和Mtype的每个组合。N_PCI和N_Data位于CAN帧数据字段中。
Physical addressing 物理寻址	In the transport layer, physical addressing refers to N-SDU, of which parameter N_TAtype (which is an extension of the N_TA parameter [14] used to encode the communication model) has the value physical. This means the N-SDU is used in 1 to 1 communication, thus physical addressing will be supported for all types of network layer messages. In terms of application, physical addressing is used by the external (or internal) tester if it knows the physical address of an ECU that should respond to a service request. When physical addressing is used, a point to point communication takes place (1 to 1 communication). Use cases are (for example) messages, such as “ReadDataByIdentifier” or “InputOutputControlByIdentifier” 在传输层，物理寻址指的是N-SDU，其中参数N_TAtype（这是用于对通信模型进行编码的 N_TA参数[14]的扩展）的值为physical。 这意味着N-SDU用于一对一通信，因此所有类型的网络层消息都将支持物理寻址。 在应用方面，如果外部（或内部）测试人员知道应响应服务请求的ECU的物理地址，则物理寻址将被使用。使用物理寻址时，会发生点对点通信（1对1通信）。 用例是（例如）消息，例如“ReadDataByIdentifier”或“InputOutputControlByIdentifier”
Single connection 单连接	The CAN Transport Layer will only manage one transport protocol communication session at a time. CAN传输层一次仅管理一个传输协议通信会话。
Connection channel 连接通道	The CAN Transport Layer is handling resources used by multiple connections in order to save RAM.When a connection becames active,the channel that is used by this connection will be unavailable for other connections. CAN传输层正在处理多个连接使用的资源以节省RAM。当连接变为活动状态时，此连接使用的通道将不可用于其他连接。
Connection 连接	A transport protocol session, either is a transmission or a reception session on a N- SDU. 传输协议会话可以是N-SDU上的发送会话或接收会话。
