　＜＜２．技術的特徴＞＞
　無線キーシステム１は、携帯端末１００と車両２００との間での無線による接続処理が、所定条件が満たされる場合に開始（換言すると、実行）されるよう制御する。そして、無線キーシステム１は、所定条件が満たされない場合に、接続処理の開始を制限する。一例として、接続処理の開始の制限は、接続処理を開始（換言すると、実行）しないことであってもよい。これにより、接続処理の開始に制限が課された期間における省電力化が実現される。接続処理に起因する電力消費が抑制されるためである。なお、携帯端末１００と２００との間の無線による接続処理は、第１の無線通信部１１０及び第１の無線通信部２１０により、即ち近距離無線通信により行われる。接続処理の制御について、以下詳しく説明する。 << 2. Technical features >>
The wireless key system 1 controls so that the wireless connection process between the mobile terminal 100 and the vehicle 200 is started (in other words, executed) when a predetermined condition is satisfied. Then, the wireless key system 1 limits the start of the connection process when the predetermined condition is not satisfied. As an example, the restriction on the start of the connection process may be that the connection process is not started (in other words, executed). As a result, power saving is realized during the period when the start of the connection process is restricted. This is because the power consumption caused by the connection processing is suppressed. The wireless connection process between the mobile terminals 100 and 200 is performed by the first wireless communication unit 110 and the first wireless communication unit 210, that is, by short-range wireless communication. The control of connection processing will be described in detail below.
　まず、サーバ３００は、予約された条件下での車両２００の利用を可能にするための予約情報を生成し、携帯端末１００及び車両２００の各々に送信する。予約情報は、予約内容を示す情報、及び携帯端末１００と車両２００とが互いを認証するために利用する認証情報を含む。予約内容を示す情報としては、例えばユーザにより車両２００を利用する時間帯として予約された、予約時間帯を示す情報が挙げられる。認証情報としては、例えば、鍵情報（例えば、ワンタイムパスワード）、接続相手の識別情報（例えば、携帯端末１００には車両２００の識別情報が送信され、車両２００にはユーザ及び／又は携帯端末１００の識別情報が送信される）、及び予約の識別情報が挙げられる。なお、車両２００に対し複数のユーザから異なる時間帯での利用が予約された場合、予約情報がリスト化された予約リストが車両２００に送信され得る。 First, the server 300 generates reservation information for enabling the use of the vehicle 200 under the reserved conditions, and transmits the reservation information to each of the mobile terminal 100 and the vehicle 200. The reservation information includes information indicating the reservation content and authentication information used by the mobile terminal 100 and the vehicle 200 to authenticate each other. Examples of the information indicating the reservation contents include information indicating the reserved time zone reserved by the user as the time zone for using the vehicle 200. As the authentication information, for example, key information (for example, a one-time password) and identification information of a connection partner (for example, identification information of the vehicle 200 is transmitted to the mobile terminal 100, and the user and / or the mobile terminal 100 is transmitted to the vehicle 200. The identification information of the reservation is transmitted), and the identification information of the reservation is mentioned. When the use of the vehicle 200 is reserved by a plurality of users in different time zones, a reservation list listing the reservation information may be transmitted to the vehicle 200.
　次いで、携帯端末１００及び車両２００は、予約情報に基づく所定条件が満たされるか否かを判定し、満たされる場合に接続処理を開始し、満たされない場合に接続処理の開始を制限する。 Next, the mobile terminal 100 and the vehicle 200 determine whether or not the predetermined conditions based on the reservation information are satisfied, start the connection process if they are satisfied, and limit the start of the connection process if they are not satisfied.
　上記所定条件は、現在時刻がユーザによる車両２００の予約時間帯に該当することを含み得る。ここで、該当するとは、予測時間帯に現在時刻が含まれることを少なくとも意味し、さらには予測時間帯の前後の所定のバッファ時間（例えば、数分）以内に現在時刻が含まれることを意味し得る。予約時間帯以外の時間においては、そもそもユーザによる車両２００の利用が想定されにくい。従って、かかる条件下で接続処理を開始することにより、ユーザの利便性を低下させずに省電力化することが可能である。 The above predetermined condition may include that the current time corresponds to the reserved time zone of the vehicle 200 by the user. Here, "corresponding" means that the predicted time zone includes at least the current time, and further means that the current time is included within a predetermined buffer time (for example, several minutes) before and after the predicted time zone. Can be done. In the time other than the reserved time zone, it is unlikely that the user will use the vehicle 200 in the first place. Therefore, by starting the connection process under such conditions, it is possible to save power without deteriorating the convenience of the user.
　上記所定条件は、携帯端末１００と車両２００とが所定の位置関係にあることを含み得る。所定の位置関係とは、例えば、携帯端末１００と車両２００との距離（直線距離又は道路距離）が所定距離以内であることである。上記所定距離は、第１の無線通信部１１０及び第１の無線通信部２１０が準拠する近距離無線通信規格において定義された通信可能距離以下に設定される。換言すると、上記所定距離は、携帯端末１００と車両２００とが近距離無線通信可能な距離に設定される。所定の位置関係であるか否かは、携帯端末１００の位置情報及び車両２００の位置情報に基づいて判定され得る。なお、これらの位置情報は、ＧＮＳＳ（Global　Navigation　Satellite　System）等の任意の位置検出手段により取得され得る。車両２００が駐車されている駐車場が既知である場合には、駐車場の位置情報が車両２００の位置情報として用いられてもよい。各々の位置情報は、例えば、サーバ３００を介して共有される。携帯端末１００と車両２００とが所定の位置関係にない場合には、ユーザが車両２００の近くにいないので、ユーザによる車両２００の利用が想定されにくい。従って、かかる条件下で接続処理を開始することにより、ユーザの利便性を低下させずに省電力化することが可能である。 The above-mentioned predetermined condition may include that the mobile terminal 100 and the vehicle 200 have a predetermined positional relationship. The predetermined positional relationship is, for example, that the distance (straight line distance or road distance) between the mobile terminal 100 and the vehicle 200 is within a predetermined distance. The predetermined distance is set to be equal to or less than the communicable distance defined in the short-range wireless communication standard to which the first wireless communication unit 110 and the first wireless communication unit 210 conform. In other words, the predetermined distance is set to a distance at which the mobile terminal 100 and the vehicle 200 can perform short-range wireless communication. Whether or not the relationship is predetermined can be determined based on the position information of the mobile terminal 100 and the position information of the vehicle 200. In addition, these position information can be acquired by arbitrary position detection means such as GNSS (Global Navigation Satellite System). When the parking lot in which the vehicle 200 is parked is known, the position information of the parking lot may be used as the position information of the vehicle 200. Each location information is shared via, for example, the server 300. When the mobile terminal 100 and the vehicle 200 are not in a predetermined positional relationship, it is difficult to assume that the user will use the vehicle 200 because the user is not near the vehicle 200. Therefore, by starting the connection process under such conditions, it is possible to save power without deteriorating the convenience of the user.
　接続処理は、携帯端末１００及び車両２００のうち、一方が接続要求信号を送信し、他方が接続要求信号の受信待ち状態になることを含む。受信側は、受信待ち状態になることで接続要求信号を受信することが可能となる。接続要求信号は、接続処理の開始を要求する信号であり、所定周期で定期的に送信される。接続要求信号の受信に成功した受信側は、送信側にレスポンスを送信する等して後続する接続処理を開始することができる。例えば、携帯端末１００及び車両２００は認証情報を送受信することで、互いを認証する。認証に成功すると、携帯端末１００と車両２００との無線接続が確立し、接続処理が完了する。ここで、携帯端末１００と車両２００との無線通信のための規格がＢＬＥである場合、送信側は接続要求信号に相当するアドバタイズパケットを数秒間隔等の所定周期で定期的に送信し、受信側はスキャン状態となり到来したアドバタイズパケットを受信する。接続要求信号を送信するにも、接続要求信号の受信待ち状態になるにも、電力が消費される。この点、所定条件が満たされる場合に接続処理を開始することにより、換言すると、所定条件が満たされない場合には接続処理の開始を制限することにより、携帯端末１００及び車両２００の省電力化が可能となる。 The connection process includes one of the mobile terminal 100 and the vehicle 200 transmitting the connection request signal and the other waiting for the connection request signal to be received. The receiving side can receive the connection request signal by entering the reception waiting state. The connection request signal is a signal requesting the start of the connection process, and is periodically transmitted at a predetermined cycle. The receiving side that succeeds in receiving the connection request signal can start the subsequent connection processing by transmitting a response to the transmitting side or the like. For example, the mobile terminal 100 and the vehicle 200 authenticate each other by transmitting and receiving authentication information. If the authentication is successful, the wireless connection between the mobile terminal 100 and the vehicle 200 is established, and the connection process is completed. Here, when the standard for wireless communication between the mobile terminal 100 and the vehicle 200 is BLE, the transmitting side periodically transmits an advertisement packet corresponding to the connection request signal at a predetermined cycle such as a few seconds interval, and the receiving side. Receives the incoming advertisement packet in the scanned state. Power is consumed both for transmitting the connection request signal and for waiting for the connection request signal to be received. In this regard, by starting the connection process when the predetermined condition is satisfied, in other words, by limiting the start of the connection process when the predetermined condition is not satisfied, the power saving of the mobile terminal 100 and the vehicle 200 can be achieved. It will be possible.
　一例として、車両２００が接続要求信号を送信し、携帯端末１００が接続要求信号の受信待ち状態になってもよい。この場合、車両２００は例えば予約時間帯にのみ接続要求信号を送信し、携帯端末１００は例えば予約時間帯にのみ受信待ち状態になる。これにより、携帯端末１００及び車両２００の予約時間帯以外の時間における省電力化が実現される。さらに、カーシェアされる車両２００が近隣に複数台存在する場合、接続要求信号の混信を抑制することが可能となる。もちろん、携帯端末１００が接続要求信号を送信し、車両２００が接続要求信号の受信待ち状態になってもよい。 As an example, the vehicle 200 may transmit a connection request signal, and the mobile terminal 100 may be in a state of waiting for reception of the connection request signal. In this case, the vehicle 200 transmits the connection request signal only during the reserved time zone, and the mobile terminal 100 is in the reception waiting state only during the reserved time zone, for example. As a result, power saving can be realized in the time other than the reserved time zone of the mobile terminal 100 and the vehicle 200. Further, when a plurality of vehicle 200s to be car-shared exist in the vicinity, it is possible to suppress interference of the connection request signal. Of course, the mobile terminal 100 may transmit the connection request signal, and the vehicle 200 may be in a state of waiting for reception of the connection request signal.
　携帯端末１００及び車両２００は、無線接続が確立し、接続処理が完了した後も継続的に信号を送受信することで、無線接続を維持してもよい。そして、ユーザが車両２００を離れる等して無線接続が解除された場合に、携帯端末１００及び車両２００は、上記の所定条件が満たされるか否かの判定及び接続処理を再度開始してもよい。他の一例として、携帯端末１００及び車両２００は、無線接続が確立して車両２００が利用可能な状態になった後は、接続要求信号及び無線接続の維持のための信号を送信しなくてもよく、受信待ち状態にならなくてもよい。 The mobile terminal 100 and the vehicle 200 may maintain the wireless connection by continuously transmitting and receiving signals even after the wireless connection is established and the connection process is completed. Then, when the wireless connection is canceled due to the user leaving the vehicle 200 or the like, the mobile terminal 100 and the vehicle 200 may restart the determination of whether or not the above predetermined conditions are satisfied and the connection process. .. As another example, the mobile terminal 100 and the vehicle 200 do not need to transmit a connection request signal and a signal for maintaining the wireless connection after the wireless connection is established and the vehicle 200 becomes available. Well, it does not have to be in the reception waiting state.
　接続処理は、車両２００をユーザによる利用が可能な状態にするための処理に関する。詳しくは、接続処理が完了すると、車両２００は、例えば、ドアをアンロックし、エンジンを始動させることで、車両２００を利用可能な状態にする。一例として、車両２００は、接続処理が完了すると自動的にこれらの処理を実行してもよい。他の一例として、車両２００は、携帯端末１００に入力されたユーザ指示を、上記接続処理により確立した無線接続を介して受信してもよく、ユーザ指示に応じてドアのロック及びアンロック、並びにエンジンの始動及び停止を実行してもよい。 The connection process relates to a process for making the vehicle 200 available to the user. Specifically, when the connection process is complete, the vehicle 200 makes the vehicle 200 available, for example by unlocking the door and starting the engine. As an example, the vehicle 200 may automatically execute these processes when the connection process is completed. As another example, the vehicle 200 may receive the user instruction input to the mobile terminal 100 via the wireless connection established by the connection process, and locks and unlocks the door according to the user instruction. The engine may be started and stopped.
　以上説明したように、接続処理の制御は、携帯端末１００、車両２００、及びサーバ３００（例えば、制御部１４０、制御部２５０及び制御部３２０）による協働により実現され得る。他に、携帯端末１００、車両２００、又はサーバ３００が単独で、接続処理の制御を行ってもよい。例えば、サーバ３００により接続処理の開始判断が行われ、携帯端末１００及び車両２００は接続処理の開始判断を行わず、サーバ３００による制御（例えば、接続処理の開始又は停止を指示する制御信号）に従って動作してもよい。 As described above, the control of the connection process can be realized by the cooperation of the mobile terminal 100, the vehicle 200, and the server 300 (for example, the control unit 140, the control unit 250, and the control unit 320). Alternatively, the mobile terminal 100, the vehicle 200, or the server 300 may independently control the connection process. For example, the server 300 determines the start of the connection process, and the mobile terminal 100 and the vehicle 200 do not determine the start of the connection process, but follow the control by the server 300 (for example, a control signal instructing the start or stop of the connection process). It may work.
　以下、図２を参照しながら、上記説明した無線接続処理の流れの一例を説明する。図２は、本実施形態に係る無線キーシステム１において実行される無線接続処理の流れの一例を示すシーケンス図である。本シーケンスには、携帯端末１００、車両２００及びサーバ３００が関与する。 Hereinafter, an example of the flow of the wireless connection processing described above will be described with reference to FIG. FIG. 2 is a sequence diagram showing an example of the flow of wireless connection processing executed in the wireless key system 1 according to the present embodiment. The mobile terminal 100, the vehicle 200, and the server 300 are involved in this sequence.
　図２に示すように、まず、携帯端末１００は、ユーザ操作に応じてサーバ３００にアクセスし、車両２００の予約を行う（ステップＳ１０２）。本予約では、ユーザが利用する車両２００、及び利用する時間帯が予約される。次いで、サーバ３００は、予約情報を携帯端末１００及び車両２００に送信する（ステップＳ１０４及びＳ１０６）。例えば、サーバ３００は、予約時間帯を示す情報、並びに、鍵情報及び車両２００の識別情報を含む認証情報を、携帯端末１００に送信する。他方、サーバ３００は、予約時間帯を示す情報、並びにユーザの識別情報を含む認証情報を、車両２００に送信する。 As shown in FIG. 2, first, the mobile terminal 100 accesses the server 300 in response to a user operation and makes a reservation for the vehicle 200 (step S102). In this reservation, the vehicle 200 used by the user and the time zone used are reserved. Next, the server 300 transmits the reservation information to the mobile terminal 100 and the vehicle 200 (steps S104 and S106). For example, the server 300 transmits the information indicating the reservation time zone and the authentication information including the key information and the identification information of the vehicle 200 to the mobile terminal 100. On the other hand, the server 300 transmits the information indicating the reserved time zone and the authentication information including the user's identification information to the vehicle 200.
　次に、携帯端末１００は、予約情報に対応する所定条件が満たされるか否かを判定する（ステップＳ１０８）。例えば、携帯端末１００は、現在時刻がユーザによる車両２００の予約時間帯に該当するか否かを判定する。所定条件が満たされない（例えば、現在時刻が予約時間帯に該当しない）と判定された場合、処理は再度ステップＳ１０８に戻る。一方で、所定条件が満たされる（例えば、現在時刻が予約時間帯に該当する）と判定された場合、携帯端末１００は、スキャンを開始する（ステップＳ１１０）。 Next, the mobile terminal 100 determines whether or not the predetermined condition corresponding to the reservation information is satisfied (step S108). For example, the mobile terminal 100 determines whether or not the current time corresponds to the reserved time zone of the vehicle 200 by the user. If it is determined that the predetermined condition is not satisfied (for example, the current time does not correspond to the reserved time zone), the process returns to step S108 again. On the other hand, when it is determined that the predetermined condition is satisfied (for example, the current time corresponds to the reserved time zone), the mobile terminal 100 starts scanning (step S110).
　同様に、車両２００は、予約情報に対応する所定条件が満たされるか否かを判定する（ステップＳ１１２）。例えば、車両２００は、現在時刻がユーザによる車両２００の予約時間帯に該当するか否かを判定する。所定条件が満たされない（例えば、現在時刻が予約時間帯に該当しない）と判定された場合、処理は再度ステップＳ１１２に戻る。一方で、所定条件が満たされる（例えば、現在時刻が予約時間帯に該当する）と判定された場合、車両２００は、接続要求信号の送信を開始する（ステップＳ１１４）。 Similarly, the vehicle 200 determines whether or not the predetermined condition corresponding to the reservation information is satisfied (step S112). For example, the vehicle 200 determines whether or not the current time corresponds to the reserved time zone of the vehicle 200 by the user. If it is determined that the predetermined condition is not satisfied (for example, the current time does not correspond to the reserved time zone), the process returns to step S112 again. On the other hand, when it is determined that the predetermined condition is satisfied (for example, the current time corresponds to the reserved time zone), the vehicle 200 starts transmitting the connection request signal (step S114).
　携帯端末１００と車両２００とが近距離無線通信可能な距離に位置し、且つ携帯端末１００がスキャン状態にあるタイミングで車両２００が接続要求信号を送信すると、携帯端末１００は、接続要求信号の受信に成功する（ステップＳ１１６）。これをトリガとして、携帯端末１００及び車両２００は、認証情報を送受信して認証を行う（ステップＳ１１８）。例えば、携帯端末１００は、鍵情報及びユーザの識別情報を車両２００に送信し、車両２００は、受信した鍵情報を検証し、受信したユーザの識別情報が予約情報に含まれるものと一致するか検証する。また、車両２００は、車両２００の識別情報を携帯端末１００に送信し、携帯端末１００は、受信した車両２００の識別情報が予約情報に含まれるものと一致するか検証する。認証に成功すると、携帯端末１００及び車両２００は、無線接続を確立する（ステップＳ１２０）。以降の処理は省略するが、例えば、車両２００は、車両２００のドア錠をアンロックしたりエンジンを始動させたりして、車両２００を利用可能な状態にする。 When the mobile terminal 100 and the vehicle 200 are located at a distance capable of short-range wireless communication and the vehicle 200 transmits a connection request signal at the timing when the mobile terminal 100 is in the scanning state, the mobile terminal 100 receives the connection request signal. Succeeds (step S116). With this as a trigger, the mobile terminal 100 and the vehicle 200 transmit and receive authentication information to perform authentication (step S118). For example, the mobile terminal 100 transmits the key information and the user's identification information to the vehicle 200, the vehicle 200 verifies the received key information, and does the received user's identification information match what is included in the reservation information? Verify. Further, the vehicle 200 transmits the identification information of the vehicle 200 to the mobile terminal 100, and the mobile terminal 100 verifies whether the received identification information of the vehicle 200 matches the reservation information. If the authentication is successful, the mobile terminal 100 and the vehicle 200 establish a wireless connection (step S120). Although the subsequent processing is omitted, for example, the vehicle 200 unlocks the door lock of the vehicle 200 and starts the engine to make the vehicle 200 available.
　以上、車両２００が接続要求信号の送信側であり、携帯端末１００が接続要求信号の受信側である場合のシーケンスを説明した。これらの役割が逆転する場合、ステップＳ１０８以降の処理の実行主体が、携帯端末１００と車両２００とで逆転する。 The sequence in the case where the vehicle 200 is the transmitting side of the connection request signal and the mobile terminal 100 is the receiving side of the connection request signal has been described above. When these roles are reversed, the execution subject of the process after step S108 is reversed between the mobile terminal 100 and the vehicle 200.
　＜＜３．補足＞＞
　以上、添付図面を参照しながら本発明の好適な実施形態について詳細に説明したが、本発明はかかる例に限定されない。本発明の属する技術の分野における通常の知識を有する者であれば、請求の範囲に記載された技術的思想の範疇内において、各種の変更例または修正例に想到し得ることは明らかであり、これらについても、当然に本発明の技術的範囲に属するものと了解される。 << 3. Supplement >>
Although the preferred embodiments of the present invention have been described in detail with reference to the accompanying drawings, the present invention is not limited to such examples. It is clear that a person having ordinary knowledge in the field of technology to which the present invention belongs can come up with various modifications or modifications within the scope of the technical ideas described in the claims. It is naturally understood that these also belong to the technical scope of the present invention.
　例えば、上記実施形態では、接続処理の開始の制限の一例として、接続処理を開始しないことを例示したが、本発明はかかる例に限定されない。例えば、接続処理の開始の制限は、制限が課されない場合と比較して低消費電力での接続処理（例えば、制限が課されない場合と比較して低頻度で及び／又は低送信電力で接続要求信号を送信する接続処理）を開始することであってもよい。これによっても、接続処理の開始に制限が課された期間における省電力化が実現される。また、かかる制限は、車両２００が通信エリア外に位置する等して予約情報の受信に失敗する状況に好適である。接続処理の開始の制限として接続処理を開始しないことが採用された場合、車両２００は、かかる状況においては予約情報の受信に失敗し、予約時間帯においても接続処理を開始しないので、ユーザは車両２００を利用することが困難になる。他方、接続処理の開始の制限として低消費電力での接続処理を開始することが採用された場合、車両２００は、かかる状況において受信に失敗した予約情報が示す予約時間帯においても低消費電力での接続処理を開始することとなる。これにより、車両２００は、予約情報の受信に成功した場合と同様に、予約時間帯において携帯端末１００との無線接続を確立することが可能となる。 For example, in the above embodiment, as an example of limiting the start of the connection process, it is exemplified that the connection process is not started, but the present invention is not limited to such an example. For example, the restriction on the start of connection processing may be a connection request with lower power consumption than when no restriction is imposed (eg, less frequently and / or with lower transmission power than when no restriction is imposed). It may be to start the connection process of transmitting a signal). This also realizes power saving during the period when the start of the connection process is restricted. Further, such a restriction is suitable for a situation where the vehicle 200 is located outside the communication area and the reception of the reservation information fails. If it is adopted not to start the connection process as a limitation of starting the connection process, the vehicle 200 fails to receive the reservation information in such a situation and does not start the connection process even in the reservation time zone, so that the user can use the vehicle. It becomes difficult to use 200. On the other hand, when it is adopted to start the connection process with low power consumption as a limitation of starting the connection process, the vehicle 200 consumes low power even in the reservation time zone indicated by the reservation information that failed to receive in such a situation. Connection processing will be started. As a result, the vehicle 200 can establish a wireless connection with the mobile terminal 100 during the reserved time zone, as in the case where the reservation information is successfully received.
　例えば、無線キーシステム１は、ユーザのプロファイルに応じて接続処理の開始を制御してもよい。具体的には、ユーザが予約時間帯に遅刻する傾向にある場合、無線キーシステム１は、予約時間帯開始直後の時間帯は低頻度で及び／又は低送信電力で接続要求信号を送信するよう制限を課し、当該時間帯が経過した後に制限を解除してもよい。これにより、ユーザの利便性を低下させずにさらに省電力化することが可能である。 For example, the wireless key system 1 may control the start of the connection process according to the profile of the user. Specifically, when the user tends to be late for the reserved time zone, the wireless key system 1 transmits the connection request signal infrequently and / or with low transmission power in the time zone immediately after the start of the reserved time zone. A limit may be imposed and the limit may be lifted after the time period has elapsed. As a result, it is possible to further save power without deteriorating the convenience of the user.
　例えば、上記では、本発明が車両に適用される例を説明したが、本発明の適用先はこれに限定されない。本発明は、複数のユーザに共有される任意の利用対象に適用可能である。一例として、船舶及び飛行機等の任意の移動体のドア錠に本発明が適用されてもよい。他の一例として、宅配ボックス及びホテルの部屋等の非移動体の錠に本発明が適用されてもよい。他の一例として、電車の指定席を利用する際の座席とユーザとの間の無線通信を介した認証、及び配車システム利用時の配車された車とユーザとの間の無線通信を介した認証等に、本発明が適用されてもよい。また、利用対象の共有の形態は、上記実施形態で説明したようなユーザと利用対象とが１対１であることに限定されず、１対複数、複数対１、及び複数対複数であってもよい。また、本発明の適用先は共有物に限定されず、一人のユーザに利用される利用対象に適用されてもよい。例えば、ユーザが自家用車を出退勤に利用する場合、出退勤が行われる時間帯に限定して接続処理が開始されてもよい。 For example, in the above, an example in which the present invention is applied to a vehicle has been described, but the application destination of the present invention is not limited to this. The present invention is applicable to any usage object shared by a plurality of users. As an example, the present invention may be applied to door locks of arbitrary moving objects such as ships and airplanes. As another example, the present invention may be applied to locks of non-mobile objects such as delivery boxes and hotel rooms. As another example, authentication via wireless communication between the seat and the user when using the reserved seat of the train, and authentication via wireless communication between the dispatched car and the user when using the vehicle allocation system. Etc., the present invention may be applied. Further, the form of sharing the usage target is not limited to the one-to-one relationship between the user and the usage target as described in the above embodiment, and may be one-to-many, multiple-to-one, and multiple-to-many. May be good. Further, the application destination of the present invention is not limited to the common object, and may be applied to the usage target used by one user. For example, when a user uses a private car for going to and from work, the connection process may be started only during the time when the user goes to and from work.
　なお、本明細書において説明した各装置による一連の処理は、ソフトウェア、ハードウェア、及びソフトウェアとハードウェアとの組合せのいずれを用いて実現されてもよい。ソフトウェアを構成するプログラムは、例えば、各装置の内部又は外部に設けられる記録媒体（非一時的な媒体：non-transitory　media）に予め格納される。そして、各プログラムは、例えば、コンピュータによる実行時にＲＡＭに読み込まれ、ＣＰＵなどのプロセッサにより実行される。上記記録媒体は、例えば、磁気ディスク、光ディスク、光磁気ディスク、フラッシュメモリ等である。また、上記のコンピュータプログラムは、記録媒体を用いずに、例えばネットワークを介して配信されてもよい。 Note that the series of processes by each device described in the present specification may be realized by using software, hardware, or a combination of software and hardware. The programs constituting the software are stored in advance in, for example, a recording medium (non-transitory media) provided inside or outside each device. Then, each program is read into RAM at the time of execution by a computer and executed by a processor such as a CPU. The recording medium is, for example, a magnetic disk, an optical disk, a magneto-optical disk, a flash memory, or the like. Further, the above computer program may be distributed via a network, for example, without using a recording medium.
　また、本明細書においてフローチャート及びシーケンス図を用いて説明した処理は、必ずしも図示された順序で実行されなくてもよい。いくつかの処理ステップは、並列的に実行されてもよい。また、追加的な処理ステップが採用されてもよく、一部の処理ステップが省略されてもよい。 Further, the processes described in the present specification using the flowchart and the sequence diagram do not necessarily have to be executed in the order shown. Some processing steps may be performed in parallel. Further, additional processing steps may be adopted, and some processing steps may be omitted.
