AUTOSARは自動車用OSの業界団体規格です。
業務で利用する場合には、会員になることを条件にしています。
2002年から20年経ち、当初の狙いの段階に近づいてきました。
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¥ |
|---|---|
| I- | Relative to upper AUTOSAR Layer (e.g. COM, DCM etc.) |
| L- | Relative to the FlexRay Interface module. |
| N- | Relative to the FlexRay Transport Protocol Layer. |
| Fr L-SDU | This is the SDU of the FlexRay Interface module. It is similar to Fr N-PDU but from the FlexRay Interface module point of view. |
| Fr L-SduId | This is the unique identifier of a Fr-L-SDU within the FlexRay Interface. It is used for referencing L-SDU’s routing properties. |
| Fr N-PDU | This is the PDU of the FlexRay Transport Layer. It contains address information, protocol control information and data (the whole Fr N-SDU or a part of it). |
| Fr N-SDU | This is the SDU of the FlexRay Transport Layer. In the AUTOSAR architecture, it is a set of data coming from the PDU Router. |
| Fr N-SduId | Unique N-SDU identifier within the FlexRay Transport Layer. It is used to reference NSDU’s routing properties. |
| I-PDU | This is the PDU of the upper AUTOSAR Layers modules (e.g. COM, DCM etc.). If data transfer via FlexRay Transport Protocol is configured, I-PDU is similar to an FrTp N-SDU. |
| PDU | In layered systems, it refers to a data unit that is specified in the protocol of a given layer. This contains user data of that layer (SDU) plus possible protocol control information. Furthermore, the PDU of layer X is the SDU of its lower layer X-1 (i.e. (X)-PDU = (X1)-SDU). |
| PduInfoType | This type refers to a structure used to store basic information to process the transmission\reception of a PDU (or a SDU), namely a pointer to its payload in RAM and the corresponding length (in bytes). |
| Channel | A channel is a resource of the FrTp module to handle communication links to other communication nodes from FrTp’s point of view (transferring Fr N-PDUs). |
| Connection | A connection specifies a communication link between different communication nodes from FrTp’s point of view. A connection defines the sender / receiver relation of communication nodes |
| PCI | Protocol Control Information |
| e.g. | lat. ‘exempli gratia’ – engl. for example |
| i.e. | lat. 'id est' – engl. that is |
| CanTp | CAN Transport Protocol |
| LinTp | LIN Transport Protocol |
| CF | Consecutive Frame Fr N-PDU |
| COM | AUTOSAR Communications module |
| DCM | Diagnostic Communication Manager module |
| DET | Default Error Tracer |
| FC | Flow Control Fr N-PDU |
| Fr | FlexRay Driver module |
| FrIf | FlexRay Interface module |
| FrTp | FlexRay Transport Protocol Layer |
| PduR | PDU Router |
| SF | Start Frame Fr N-PDU |
| LF | Last Frame Fr N-PDU |
| TP | Transport Protocol Layer |
| SDU | In layered systems, this refers to a set of data that is sent by a user of the services of a given layer, and is transmitted to a peer service user, whilst remaining semantically unchanged. |
| AUTOSAR | Automotive Open System Architecture |
| SWS | Software Specification |
| MISRA | Motor Industry Software Reliability Association |
| ISO | International Standard Organisation |
| ID | Identifier |
| OS | Operating System |
| MCAL | Microcontroller Abstraction Layer |
| CPU | Central Processing Unit |
| ROM | Read Only Memory |
| RAM | Random Access Memory |

| AF | Acknowledge Frame (please refer to ISO 10681-2) |
| SN | Sequence Number (please refer to ISO 10681-2) |
| FrTp_As | Timer Parameter for a sender. Time for transmission of the FlexRay frame (any N_PDU) on the sender side. (please refer to ISO 10681-2) |
| FrTp_Ar | Timer Parameter for a receiver. Time for transmission of the FlexRay frame (any N_PDU) on the receiver side (please refer to ISO 10681-2) |
| FrTp_BS | Timer Parameter for a sender. Time until reception of the next FlowControl N_PDU. (please refer to ISO 10681-2) |
| FrTp_Br | Timer Parameter for a receiver. Time until transmission of the next FlowControl N_PDU. (please refer to ISO 10681-2) |
| FrTp_Cs | Timer Parameter for a sender. Time until transmission of the next ConsecutiveFrame N_PDU/LastFrame N_PDU. (please refer to ISO 10681-2) |
| FrTp_Cr | Timer Parameter for a receiver. Time until reception of the next ConsecutiveFrame N_PDU (please refer to ISO 10681-2) |
