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。

• Contradicting requirements improved
• Editorial changes
用語(terms)
| Term | Description |
|---|---|
| Method | a method, procedure, function, or subroutine that is called/invoked. |
| Parameters | input, output, or input/output arguments of a method or an event |
| Remote Procedure Call (RPC) | a method call from one ECU to another that is transmitted using messages |
| Request | a message of the client to the server invoking a method |
| Response | a message of the server to the client transporting results of a method invocation |
| Request/Response communication | a RPC that consists of request and response |
| Fire&Forget communication | a RPC call that consists only of a request message |
| Event | A uni-directional data transmission that is only invoked on changes or cyclically and is sent from the producer of data to the consumers. One event could even be both sent cyclically and spontaneously on change. This is completely in the responsibility of the sending application because the receiver has no means at all to distinguish between those two. |
| Field | a field does represent a status and thus has a valid value at all times on which getter, setter and notfier act upon. |
| Notification Event | an event message the notifier of a field sends. The message of such a notifier cannot be distinguished from the event message; therefore, when refering to the message of an event, this shall also be true for the messages of notifiers of fields. |
| Getter | a Request/Response call that allows read access to a field. |
| Setter | a Request/Response call that allows write access to a field. |
| Notifier | sends out event message with a new value on change of the value of the field. |
| Service | a logical combination of zero or more methods, zero or more events, and zero or more fields (empty service is allowed, e.g. for announcing non-SOME/IP services in SOME/IP-SD) |
| Eventgroup | a logical grouping of events and notification events of fields inside a service in order to allow subscription |
| Service Interface | the formal specification of the service including its methods, events, and fields |
| Service Instance | software implementation of the service interface, which can exist more than once in the vehicle and more than once on an ECU |
| Server | The ECU offering a service instance shall be called server in the context of this service instance. |
| Client | The ECU using the service instance of a server shall be called client in the context of this service instance. |
| Union or Variant | a data structure that dynamically assumes different data types. |
| Offering a service instance | that one ECU implements an instance of a service and tells other ECUs using SOME/IP-SD that they may use it. |
| Finding a service instance | to send a SOME/IP-SD message in order to find a needed service instance. |
| Requiring a service instance | to send a SOME/IP-SD message to the ECU implementing the required service instance with the meaning that this service instance is needed by the other ECU. This may be also sent if the service instance is not running; thus, was not offered yet. |
| Releasing a service instance | to sent a SOME/IP-SD message to the ECU hosting this service instances with the meaning that the service instance is no longer needed. |
| Server-Service-Instance-Entry | The configuration and required data of a service instance the local ECU offers, is called Server-Service-Instance-Entry at the ECU offering this service (Server). |
| Client-Service-Instance-Entry | The configuration and required data of a service instance another ECU offers, is called Client-Service-Instance-Entry at the ECU using this service (Client) |
| Publishing an eventgroup | to offer an eventgroup of a service instance to other ECUs using a SOME/IP-SD message |
| Subscribing an eventgroup | to require an eventgroup of a service instance using a SOME/IPSD message. |
| unicast event | Events which are transmitted to a unicast endpoint by the ECU which hosts a server service. The unicast endpoint is provided by a particular client service which has subscribed to this server service within the Endpoint Option referenced by a SubscribeEventgroup entry (see client service unicast endpoint). |
| multicast event | Events which are transmitted to a multicast endpoint by the ECU which hosts a server service. A multicast endpoint could be provided by the server service (see server service multicast endpoint) and client service (see client service multicast endpoint). |
| server service multicast endpoint | Multicast endpoint (including IP multicast address, port, and protocol) provided by the server service to announce where the server service transmits multicast-events to with respect to the configured MULTICAST_THRESHOLD. |
| client service unicast endpoint | Unicast endpoint (including IP multicast address, port, and protocol) provided by the client service to announce where the client service expects to receive events from the corresponding server service. Please note, if the MULTICAST_THRESHOLD has been exceeded on server service side, then the server service automatically switches from the client service unicast endpoint to the server service multicast endpoint to provide events. |
| client service multicast endpoint | Multicast endpoint (including IP multicast address, port, and protocol) provided by the client service to announce where the client service expects to receive events from the corresponding server service. This could be used alternatively to a client unicast endpoint. Please note, if the MULTICAST_THRESHOLD has been exceeded on server service side, then the server service automatically switches from the client service multicast endpoint to the server service multicast endpoint. |
| Security Association | Mechanism to provide secure encrypted communication between commuication partners. This for example applies to IPSec, MACsec, (d)TLS and possible other security protocols. |
| Secured Port | Network Port, on which a Security association is applied to be secured from unauthorized communication. |
