用語(terms)
| term | Description |
|---|---|
| CC | Communication Controller |
| NM | Network Management |
| WCET | Worst Case Execution Time |
| DET | Default Error Tracer. AUTOSAR Module for detection and reporting of errors during development. |
| SRS | Software requirements specification |
| SWS | Software working specification |
| API | Application program interface |
| Com | Communication module |
| OS | Operating system |
| SchM | Schedule Manager |
| PDU | Protocol data unit |
| CPU | Central processing unit |
| PNL | Partial Network Learning |
| FrIf | Abbreviation for the FlexRay Interface |
| FrNm | Abbreviation for the Network Management on FlexRay |
| NmIf | Abbreviation for the generic Network Management |
| ECU | Electronic control unit |
| ComM | Communication manager |
| FrSm | FlexRay State Manager |
| HW | Hardware |
| Bus-Sleep Mode | Network mode where all interconnected communication controllers are in the sleep mode. |
| NM-Network | Instance of the FlexRay NM to handle one physical FlexRay Bus. Caution: The FlexRay Bus contains two FlexRay channels which cannot be handled independent of the other. Therefore the NM-Network covers both FlexRay bus channels. This is equivalent to one NM-Cluster |
| Network requested | NM network is requested if FrNm_NetworkRequest has been called and neither the network has been released nor Bus Sleep Mode has been entered afterwards |
| Network released | NM network is released if FrNm_NetworkRelease has been called and network has not been requested afterwards |
| Repeat Message Request active | A Repeat Message Request is active if FrNm_RepeatMessageRequest has been called or a NM PDU with Repeat Message Request bit set has been received in Network Mode. It is not active anymore if Repeat Message State is left or Bus Sleep Mode is entered. |
| NM Data Cycle | Number of FlexRay cycles necessary for all nodes to be able to send NM Data at least once. |
| NM Message | Packet of information exchanged for purposes of the NM algorithm. |
| NM Repetition Cycle | Number of FlexRay cycles where no change of voting behavior is possible. Value has to be a multiple of the NM Voting Cycle. Used to |
| improve the reliability of the voting. | |
| NM Slot | Slot reserved for purposes of network management. |
| NM Timeout | Timeout in the NM algorithm that initiates transition into Bus-Sleep Mode. |
| NM User Data | Supplementary application specific data that is sent independent of the NM Vote on the bus. |
| NM Voting Cycle | Number of FlexRay cycles necessary for all nodes to vote at least once. NM-Vote Information transmitted using the FlexRay Bus indicating the vote of a ECU to keep the bus awake |
| NM-Vector | FlexRay NM Vector is the aggregated data available when the FlexRay CC optional NM Hardware Vector Service is used. |
| NM-Data | Data related to NM transmitted using the FlexRay Bus. |
| NM-Cluster | Obsolete, equivalent to NM-Network |
| CBV | Control bit vector |
| ClusterAwakeVote | At least one Node other than itself votes for keeping the cluster awake. |
| Positive NMVote in static segment | NM-Vote PDU reception or transmission with Voting Bit set to '1' |
| Positive NMVote in dynamic segment | NM-Vote PDU received or transmitted |
| Negative NMVote in static segment | NM-Vote PDU reception or transmission with Voting Bit set '0' |
| Negative NMVote | In dynamic segment: NM-Vote PDU is neither received nor transmitted |
| Top-level PNC coordinator | The top-level PNC coordinator is an ECU that acts as PNC gateway in the network and that handles at least one PNC as actively coordinated on all assigned channels. If synchronized PNC shutdown is enabled, the toplevel PNC coordinator triggers for these PNCs the shutdown, if no other ECU in the network request them. |
| Intermediate PNC coordinator | An intermediate PNC coordinator is an ECU that acts as PNC gateway in the network and that handles at least one PNC as passively coordinated on at least one assigned channel. If synchronized PNC shutdown is enabled, it forwards received shutdown requests for these PNCs to the corresponding actively coordinated channels and starts their shutdown accordingly. |
| PNC leaf node | A PNC leaf node is an ECU that acts not as a PNC coordinator at all in the network. It processes PN shutdown message as usual NM messages. |
| PN shutdown message | A top-level PNC coordinator transmit PN shutdown messages to indicate asynchronized PNC shutdown across the PN topology. A PN shutdown message is as NM message which has PNSR bit in the control bit vector and all PNCs which are indicated for a synchronized shutdown set to '1'. |
