AUTOSARは、自動車用OSの業界団体規格です。
2002年から20年経ち、ようやく実用化してきました。
MATLABでモデルさえ記述すれば、あとは自動生成だけでソフトが完成するところまで、あと一歩です。
Ethernet, UNIXが生まれて20年で大衆化したのと同じように考えると分かりやすいでしょう。
AUTOSARの上で動く、クラウド対応のミドルウェアが出て、開発も運用もクラウドになれば、一気にAUTOSARは大衆化するでしょう。

用語(terms)
| Term | Description |
|---|---|
| CanIf | CAN Interface module |
| CanNm | CAN Network Management module |
| CC | Communication controller |
| ComM | Communication Manager module |
| EcuM | ECU State Manager module |
| DEM | Diagnostic Event Manager module |
| Nm | Generic Network Management Interface module, this ist the abreviation used for this module throughout this specification |
| NM | Network Management |
| OEM | Original Equipment Manufacturer |
| CBV | Control Bit Vector in NM-message |
| PNC | Partial network cluster |
| Bus-Sleep | Mode Network mode where all interconnected communication controllers are in the sleep mode. |
| NM-Channel | Logical channel associated with the NM-cluster |
| NM-Cluster | Set of NM nodes coordinated with the use of the NM algorithm. |
| NM-Coordinator | A functionality of the Nm which allows coordination of network sleep for multiple NM Channels. |
| NM-Message | Packet of information exchanged for purposes of the NM algorithm. |
| NM-Timeout | Timeout in the NM algorithm that initiates transition into BusSleep Mode. |
| NM User Data | Supplementary application specific piece of data that is attached to every NM message sent on the bus. |
| Node Identifier | Node address information exchanged for purposes of the NM algorithm. |
| Node Identifier List | List of Node Identifiers recognized by the NM algorithm. |
| Bus | Physical communication medium to which a NM node/ecu is connected to. |
| network | Entity of all NM nodes/ecus which are connected to the same bus. |
| channel | Logical bus to which the NM node/ecu is connected to. |
| Coordinated shutdown S | hutdown of two or more busses in a way that their shutdown is finished coinciding. |
| Coordination algorithm | Initiation of coordinated shutdown in case all conditions are met. |
| PN info | Represent the Partial Network information in a NM frame |
| PN info range | Represent the length of a Partial Network information in bytes |
| PNC bit | One bit which represent a particular Partial Network in the Partial Network Info Range |
| PN filter mask | Vector of filter mask bytes defined by configuration container(s) NmPnFilterMaskByte per channel to filter relevant PNC requests for the PNC timer handling |
| 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 top-level PNC coordinator triggers for these PNCs the shutdown, if no other ECU in the network request them. Note that for different PNCs it is possible to have different toplevel PNC coordinators. For the same PNC only one top-level coordinator is supported. |
| 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 act neither as top-level PNC coordinator nor as an intermediate PNC coordinator. It act as an ECU without a PNC gateway in the network and process PN shutdown message as usual NM messages. |
| PN shutdown request message | A top-level PNC coordinator transmits PN shutdown messages to indicate a synchronized PNC shutdown across the PN topology. A PN shutdown message is a NM message which has PNSR bit in the control bit vector and all PNCs which are indicated for a synchronized shutdown set to ’1’. An intermediate PNC coordinator which receive a PN shutdown message and forward the PN information as PN shutdown message on the affected channels. Note: An intermediate PNC coordinators has to forward the PN information of received PN shutdown message as fast as possible to ensure a nearly synchronized shutdown of the affected PNCs across the PN topology. |
