用語(terms)
| Term | Description |
|---|---|
| AddressAndLengthFormat Identifier | Defines the number of bytes used for the memoryAddress and memorySize parameter in the request messages. |
| Application Layer | The Application Layer is placed above the RTE. Within the Application Layer the AUTOSAR Software-Components are placed. |
| Atomic Sender/Receiver interface | An atomic sender-receiver interface can be used to group DID data elements into one record data element prototype. All data elements can be read or write having a single read or write operation. |
| Channel | A link at which a data transfer can take place. If there is more than one Channel, there is normally some kind of ID assigned to the Channel. |
| Concurrent TesterPresent | A UDS service TesterPresent with set suppressPosRspMsgIndicationBit (3E 80) which is received with functional addressing. It is also known as keep-alive logic.. |
| Diagnostic Channel | A link at which a data transfer between a diagnostic tool and an ECU can take place. Example: An ECU is connected via CAN and the diagnostic channel has an assigned CAN-ID. Diagnostic channels connected to other bus-systems such as MOST, FlexRay, LIN, etc. are also possible. |
| External Diagnostic Tool | A device which is NOT permanently connected to the vehicle communication network. This External Diagnostic Tool can be connected to the vehicle for various purposes, as e.g. for: • development • manufacturing • service (in a garage) Example External Diagnostic Tools are: • a diagnostic tester • an OBD scan tool The External Diagnostic Tool is to be connected by a mechanic to gather information from ”inside” the car. |
| Freeze Frame | A set of the vehicle/system operation conditions at a specific time. |
| Functional Addressing | The diagnostic communication model where a group or all nodes of a specific communication network receive a message from one sending node (1-n communication). This model is also referred to as ’broadcast’ or ’multicast’. OBD communication will always be done in the Functional Addressing mode. |
| Internal Diagnostic Tool | A device/ECU which is connected to the vehicle communication network. The Internal Diagnostic Tool can be used for: • advanced event tracking • advanced analysis • for service The behavior of the Internal Diagnostic Tool can be the same as of an External Diagnostic Tool. The notion of ”Internal Diagnostic Tool” does not imply that it is included in each ECU as an AUTOSAR Software-Component. |
| Physical Addressing | The diagnostic communication model where a node of a specific communication network receives a message from one sending node (1-1 communication). This model is also referred to as ’unicast’. |
| UDS Service | this refers to a UDS Service as defined in ISO14229-1 [1]. |
| OBD Scan tool | See definition External Diagnostic Tool. |
| OBD Service | This refers to an OBD Service as defined in ISO15031-5 [2]. |
| OBD UDS DTC separation | The feature will report a different 3 byte DTC number for SAE J1979-2 based UDS communication than for none J1979-2 UDS communication. |
| periodic transmission rate | Time interval value that defines the time between two calls of a periodic data identifier transmission. The value is configuration specific and there are separate values for fast, medium and slow periodic data transmission. The configured value is always an integer multiple of the Dcm main task time. |
| API | Application Programming Interface |
| CAN | Controller Area Network |
| CEMR | ControlEnableMaskRecord |
| Dcm | Diagnostic Communication Manager |
| Dem | Diagnostic Event Manager |
| Det | Default Error Tracer |
| DID | Data Identifier |
| DSD | Diagnostic Service Dispatcher (submodule of the Dcm module) |
| DSL | Diagnostic Session Layer (submodule of the Dcm module) |
| DSP | Diagnostic Service Processing (submodule of the Dcm module) |
| DTC | Diagnostic Trouble Codes |
| ID | Identifier |
| LIN | Local Interconnect Network |
| MCU | Micro-Controller Unit |
| MOST | Media Orientated System Transport |
| NRC | Negative Response Code |
| OBD | On-Board Diagnosis |
| OSI | Open Systems Interconnection |
| PDID | Periodic Data Identifier, periodically send by the Dcm after a request of ReadDataByPeriodicIndentifer |
| PDU | Protocol Data Unit |
| PID | Parameter Identifier |
| RCRRP | Response correctly received - response pending |
| RID | Routine Identifier |
| ROE | ResponseOnEvent |
| RTE | Runtime Environment |
| SAP | Service Access Point |
| SDU | Service Data Unit |
| SID | Service Identifier |
| SW-C | Software-Component |
| TP | Transport Protocol |
| UDS | Unified Diagnostic Services |
| Xxx_ | Placeholder for an API provider |
| SPRMIB | suppressPosRspMsgIndicationBit |
