- the timeout time is an index for the time until the data input to the queuing buffer section 13A is output via the buffer section 13A. Therefore, as shown in FIG. 15, in step S94 instead of step S91, the compute service function unit 12 checks the database unit 16 to confirm the timeout period of each car 31 included in the vehicle configuration information, A queue of the queuing buffer unit 13A that stores the information is specified.
- the time-out time here does not need to be a specific numerical value, and queue A is for a "short” vehicle, queue B is for a "normal” vehicle, and queue C is for a "long” vehicle. do. Subsequent processing is the same as that of the second embodiment. Also, the timeout time may be a predetermined numerical value such as 100 ms, 1 second, or 3 seconds.
- the priority of the distribution order is set based on the importance and urgency of campaigns, the presence or absence of billing applications, etc. in the vehicle configuration information of each vehicle. For example, “high”, “normal”, and “low” are set. Therefore, as shown in FIG. 16, in step S95 instead of step S94, the compute service function unit 12 checks the database unit 16 to determine the priority of the delivery order of each car 31 included in the vehicle configuration information. Then, the queue of the queuing buffer unit 13A that stores the information is specified. If the vehicle is "expensive", it is cue A, if it is "normal”, it is cue B, and if it is "low”, it is cue C. After that, the processing is the same as that of the third embodiment.
- the priority of the distribution order is set, for example, "high”, “normal”, “low” based on the attributes of the campaign.
- Campaign attributes are, for example, at least one or more of conditions such as the importance and urgency of the campaign, and whether or not the content is chargeable content.
- the price table of the car 31 included in the vehicle configuration information is confirmed to identify the queue in which the information is stored.

- the response speed from the OTA center 1 is not much of a problem assuming that background processing is performed as in the embodiment described later.
- communication processing of vehicle configuration information transmitted from the smartphone 32 or the PC 33 is foreground processing, and a slow response speed poses a problem in terms of UX (User experience).
- step S96 instead of step S95 in the fourth embodiment, the compute service function unit 12 checks the database unit 16 and checks the vehicle configuration information. Specifies whether the transmission is from the car 31 , the smart phone 32 or the PC 33 . At the same time, the price table of the car 31 is confirmed and specified.
- the queuing buffer unit 13B there are a queue group V for the car 31, a queue group S for the smart phone 32, and a queue group P for the PC 33, and each queue group has queues A to C. Distribution to each queue A to C by the price table is the same as in the second embodiment.
- step S97 which replaces step S93, the process of accumulating the vehicle configuration information passed to the queuing buffer unit 13B for a certain period of time is the same.
- the queue groups V, S, and P have different waiting time settings. For example, set as follows. ⁇ Cue group V> A: 100ms B: 1s C: 3s ⁇ Queue group S> A: 50ms B: 70ms C: 90ms ⁇ Queue group P> A: 100ms B: 200ms C: 300ms
- the fifth embodiment by changing the waiting time setting of each queue in the queuing buffer unit 13B according to the transmission source of the vehicle configuration information and the price table of the car 31, the value of the user is reduced. It is possible to provide a high-quality OTA service with enhanced experience, so-called UX.

For example, a ping command is transmitted as a command to check whether or not (see FIG. 20, S98(1)). As a result, each compute service function unit and compute service processing unit can be maintained in a warm standby state.
- the compute server section 28 is an example of a reserve state setting section.

Abstract
Description
本発明は上記事情に鑑みてなされたものであり、その目的は、複数台の車両と無線通信を行なうセンタ装置を、より低コストで構成することにある。
以下、第1実施形態について説明する。図1に示すように、本実施形態のセンタ装置であるOTAセンタ1は、配信システム2及び共通システム3を備えている。共通システム3においては、車両であるクルマ31に配信するECUの更新プログラムやデータを含む配信パッケージが生成されて管理され、生成された配信パッケージは配信システム2を介して、無線通信により、すなわちOTAによってクルマ31に配信される。
尚、図示した構成では、説明の便宜上、指令やデータの送受信を線で示している。しかし、線で表示されていなくても、処理部や関数部、管理部の呼出しや、データベース部やストレージ部へのアクセスは可能である。
・オンデマンドでプログラムコードを実行するため、サーバを使用することなく、コンピューティングサービスを使用する。
・目的が1つだけの、ストレートな関数とする。
・プッシュベースのイベント駆動型パイプラインを構成する。
・より厚く強力なフロントエンドを構成する。
といったものになる。

・Amazon Kinesis :キューイングバッファ部13に相当する。
・AWS Fargate :コンピュートサービス関数部14及び
コンピュートサービス処理部15に相当する。
・Amazon S3 :ファイルストレージ部17、18及び26に相当する。
・Amazon Aurora :データベース部19、25及び27に相当する。
尚、CDN77はCDN配信部21に相当するが、これはCDN77(株)が提供しているサービスである。これをAWSが提供しているAmazon CloudFrontサービスに置き換えてもよい。
以下、上記の各処理の詳細について説明する。
図4に示すように、APIゲートウェイ部11が、クルマ31から車両構成情報のHTTPS(Hypertext Transfer Protocol Secure)リクエストを受信する(S1)。そのリクエスト内容は、例えばVIN(Vehicle Identification Number)と、各ECUのハードウェアIDと、各ECUのソフトウェアIDなどである。次に、APIゲートウェイ部11はコンピュートサービス関数部12を起動すると、受信した車両構成情報を当該関数部12に渡す(S2)。
尚、コンピュートサービス処理部15のコンテナアプリとしては、キャンペーン情報の生成に関わるコンテナアプリ、配信パッケージの登録に関わるコンテナアプリ、パッケージの生成に関わるコンテナアプリ、が含まれている。コンピュートサービス関数部14は、渡された情報を解釈して対応するコンテナアプリを起動する。
尚、ステップS9において、キャンペーン情報があり、クルマ31に配信する上で必要な情報が揃っている場合は、ステップS10に移行する。
図5に示すように、OTA運用者34は、キャンペーン情報登録のHTTPSリクエストを送信する(S21)。APIゲートウェイ部11はコンピュートサービス関数部12を起動すると、受信したキャンペーン情報を渡す(S22)。
尚、オリジンサーバとは、オリジナルのデータが存在するサーバである。本実施形態では、ファイルストレージ部18には、更新対象のソフトウェアパッケージとダウンロード用のURL情報の全てが保存される。
図6に示すように、クルマ31、より具体的にはクルマ31に搭載されているDCM(Data Communication Module)及びセントラルECUからなるOTAマスタが、キャンペーン情報に含まれているダウンロードURL情報を元に、CDN配信部21にアクセスする(S41)。CDN配信部21は、クルマ31から要求されたソフトウェアパッケージを、自身のキャッシュメモリに保持しているか否かを判断する(S42)。キャッシュメモリに保持していれば、CDN配信部21は、クルマ31にソフトウェアパッケージを送信する(S43)。
図7に示すように、APIゲートウェイ部22は、OEMバックオフィス4の第1サーバ6から、ソフトウェア更新データ及びその関連情報の登録要求を、HTTPSリクエストとして受信する(S51)。APIゲートウェイ部22は、コンピュートサービス関数部24を起動して、ソフトウェア更新データ及び関連情報を渡す(S52)。コンピュートサービス関数部24は、ソフトウェア更新データ及び関連情報をファイルストレージ部26に格納する(S53)。
図8に示すように、OTA運用者34が、案件情報の登録を行うため、APIゲートウェイ部11に対して案件情報のHTTPSリクエストを送信する(S61)。案件情報は、ある配信パッケージを適用可能なECUのハードウェア情報やソフトウェア情報を纏めたものである。APIゲートウェイ部11は、コンピュートサービス関数部12を起動すると、受信した案件情報を当該関数部12に渡す(S62)。
また、キューイングバッファ部13は、車両構成情報、キャンペーン情報、案件情報を1つのキューイングバッファに格納しても良いし、情報の種類ごとに異なるキューイングバッファ部13に格納しても良い。
以下、第1実施形態と同一部分には同一符号を付して説明を省略し、異なる部分について説明する。図13に示すように、一般に、クルマ31の価格帯によって台数のシェアは異なり、ハイエンドモデルのシェアは低く、ミドル、ローエンドモデルのシェアは高い。そこで、キューイングバッファ部13Aにおいて、クルマ31の価格帯によりキューを分けて、ハイエンドモデルのOTA処理を優先的に実行させる。
図14に示すように、ステップS1及びS2を実行すると、コンピュートサービス関数部12は、データベース部16をチェックして、車両構成情報に含まれているクルマ31のVINを確認し、そのVINに基づいて価格テーブルを確認し、当該車両構成情報を格納するキューイングバッファ部13Aのキューを特定する。例えばハイクラスの車両であればキューA,ミドルクラスの車両であればキューB、ロークラスの車両であればキューCとする(S91)。コンピュートサービス関数部12は、アクセスバッファ制御部及びキューイングバッファ制御部の一例である。或は、車両構成情報に価格帯を示す情報が含まれていても良い。
第3実施形態では、第2実施形態における車両の価格帯に替えて、各車両の車両構成情報に、キューイングバッファ部13Aにおけるタイムアウト時間が設定されている。タイムアウト時間は、キューイングバッファ部13Aに入力されたデータが、当該バッファ部13Aを経て出力されるまでの時間に対する指標である。そこで、図15に示すように、ステップS91に替わるステップS94では、コンピュートサービス関数部12は、データベース部16をチェックして、車両構成情報に含まれている各クルマ31のタイムアウト時間を確認し、当該情報を格納するキューイングバッファ部13Aのキューを特定する。ここでのタイムアウト時間は、具体的な数値である必要はなく、「短い」の車両であればキューA、「普通」の車両であればキューB、「長い」の車両であればキューCとする。以降は第2実施形態の処理と同様である。また、タイムアウト時間は、100ms、1秒、3秒など、所定の数値でも良い。
第4実施形態では、第3実施形態におけるタイムアウト時間の設定に替えて、各車両の車両構成情報に、キャンペーンの重要度や緊急度、課金アプリの有無等に基づいて、配信順序の優先度が例えば「高い」、「普通」、「低い」といったように設定されている。そこで、図16に示すように、ステップS94に替わるステップS95では、コンピュートサービス関数部12は、データベース部16をチェックして、車両構成情報に含まれている各クルマ31の配信順序の優先度を確認し、当該情報を格納するキューイングバッファ部13Aのキューを特定する。「高い」の車両であればキューA、「普通」の車両であればキューB、「低い」の車両であればキューCとする。以降は第3実施形態の処理と同様である。
第5実施形態では、第2実施形態と同様に車両構成情報に含まれているクルマ31の価格テーブルを確認して当該情報を格納するキューを特定する。それに加えて、車両構成情報の送信が、クルマ31以外にスマートフォン32や、パーソナルコンピュータ(PC)33のような情報通信端末からも可能である場合に、コンピュートサービス関数部12において送信元を判別し、送信元にも応じてキューイングバッファ部13Bのキューを特定する。コンピュートサービス関数部12は、送信元判別部の一例である。
<キューグループV>
A:100ms
B:1s
C:3s
<キューグループS>
A:50ms
B:70ms
C:90ms
<キューグループP>
A:100ms
B:200ms
C:300ms
サーバレスアーキテクチャでは、イベントが発生した時点でリソースが割り当てられるため、起動するのに比較的時間を要する。そこで、第6実施形態では、サーバレスアーキテクチャを採用するコンピュートサービス関数部12,14,20及び24、並びにコンピュートサービス処理部15及び23をウォームスタンバイ状態にすることで、起動時間の短縮を図る。
図21に示す第7実施形態のOTAセンタ1Bでは、配信システム2Bにおいて、コンピュートサーバ部29が追加されている。コンピュートサーバ部29は、サーバアーキテクチャを採用しており、APIゲートウェイ部11、ファイルストレージ部17及びデータベース部19との間でデータを入出力する。コンピュートサーバ部29は、情報処理サーバの一例である。
図23に示す第8実施形態は、第1実施形態の図2に示した、AWSを用いて構成したOTAセンタのバリエーションを示す。図2との主な相違点は、「AWS Fargate」の機能の一部を「Elastic Load Balancing」に担わせて、「Elastic Load Balancing」がコンピュートサービス関数部14に相当し、「AWS Fargate」がコンピュートサービス処理部15に相当するように構成した点である。
サーバレスアーキテクチャを採用するアプリケーションプログラムは、AWSを利用するものに限らず、その他のクラウドコンピューティングサービスを利用しても良い。
コンピュートサーバ部28が周期的に送信するコマンドはpingコマンドに限らず、通信可能か否かを調べるコマンドであれば良い。
情報携帯端末は、スマートフォンやパーソナルコンピュータに限らない。
このようにサーバレスアーキテクチャを設計するには、サーバアーキテクチャの設計では考慮しない事項を満たす必要がある。そのため、サーバアーキテクチャを前提とするソフトウェアシステム構成、設計、仕様などに基づいて、サーバレスアーキテクチャを採用するシステムは構築できない。
