　この構成において、情報通信システム１のうちの操作制限システム２は、まず、４つのスマートフォン１０のなかから、端末ホルダ２０に最も近いスマートフォン１０を特定する。端末ホルダ２０は、運転席１０１Ａに設置されている。このため、特定したスマートフォン１０は、運転者が保有するスマートフォンであると判定される。そして、操作制限システム２は、そのスマートフォン１０の使用を制限する。これにより、運転者による、運転中でのスマートフォン１０の使用を制限できる。 In this configuration, the operation restriction system 2 of the information communication system 1 first specifies the smartphone 10 closest to the terminal holder 20 among the four smartphones 10. The terminal holder 20 is installed in the driver's seat 101A. For this reason, it is determined that the specified smartphone 10 is a smartphone owned by the driver. Then, the operation restriction system 2 restricts the use of the smartphone 10. Thereby, the driver's use of the smartphone 10 while driving can be restricted.
　また、情報通信システム１のうちの運転管理システム３は、保護ケース３０を介して、スマートフォン１０を保有する運転者に関する情報を、車両１００の外部装置２００へ送信する。これにより、車両１００の外部から運転者の状況を把握することができる。さらに、運転管理システム３は、保護ケース３０の後述する保護ケース制御部３１が、上述の背面検知信号を受信した場合に、車両１００に対して車両１００とは別の物体が接近していることを示す警告動作（例えば、警告音の鳴動、警告表示、またはスマートフォン１０に警告動作を実行させるための操作信号の入力）を行う。これにより、車両１００と当該別の物体とが接触する事故を未然に防ぐことができる。 Further, the operation management system 3 of the information communication system 1 transmits information related to the driver who holds the smartphone 10 to the external device 200 of the vehicle 100 via the protective case 30. Thus, the driver's situation can be grasped from the outside of the vehicle 100. Furthermore, in the operation management system 3, when a protection case control unit 31 described later of the protection case 30 receives the above-described back surface detection signal, an object other than the vehicle 100 is approaching the vehicle 100. A warning operation (for example, generation of a warning sound, a warning display, or input of an operation signal for causing the smartphone 10 to execute the warning operation) is performed. Thereby, the accident which the vehicle 100 and the said another object contact can be prevented beforehand.

However, the specific signal transmission unit 24 may be included in the terminal holder control unit 21.
　コネクタ２３は、前記したように、車両１００から電力を得るために、車両１００のシガーソケットに接続されるコネクタである。スマートフォン１０が端末ホルダ２０に載置され、スマートフォン１０のジャックが端末ホルダ２０の接続プラグ２２に接続されると、電力変換回路２３１は、コネクタ２３から取り込んだ電力を変換（昇圧または降圧）して、接続プラグ２２を介してスマートフォン１０へ電力を供給する。ただし、端末ホルダ２０は、スマートフォン１０へ電力を供給する機能を有していなくてもよい。 The connector 23 is a connector connected to a cigar socket of the vehicle 100 in order to obtain power from the vehicle 100 as described above. When the smartphone 10 is placed on the terminal holder 20 and the jack of the smartphone 10 is connected to the connection plug 22 of the terminal holder 20, the power conversion circuit 231 converts (boosts or steps down) the power taken from the connector 23 , Supply power to the smartphone 10 via the connection plug 22. However, the terminal holder 20 may not have the function of supplying power to the smartphone 10.
　加速度検出部２５は、端末ホルダ２０にかかる加速度、すなわち車両１００の加速度を検出する。加速度検出部２５は、例えば、静電容量型加速度センサ、または半導体ピエゾ抵抗型加速度センサを含む。 The acceleration detection unit 25 detects the acceleration applied to the terminal holder 20, that is, the acceleration of the vehicle 100.

The terminal holder control unit 21 determines whether the acceleration of the vehicle 100 detected by the acceleration detection unit 25 is equal to or greater than a predetermined value.
　特定信号発信部２４は、端末ホルダ制御部２１によって車両１００の加速度が所定値以上であると判定された場合に、保護ケース３０の後述する保護ケース制御部３１へ端末特定信号を送信する発信手段である。端末特定信号は、端末ホルダ２０と、４つのスマートフォン１０それぞれとの相対距離を比較するための近距離無線信号である。端末特定信号は、赤外線であってもよいし、Ｂｌｕｅｔｏｏｔｈ（登録商標）であってもよい。 The specific signal transmission unit 24 is a transmission unit that transmits a terminal identification signal to a protection case control unit 31 described later of the protection case 30 when the terminal holder control unit 21 determines that the acceleration of the vehicle 100 is equal to or higher than a predetermined value. It is. The terminal identification signal is a short distance wireless signal for comparing the relative distance between the terminal holder 20 and each of the four smartphones 10. The terminal specific signal may be infrared or Bluetooth (registered trademark).
　＜２．２．保護ケースの詳細な構成＞
　図５は、保護ケース３０の電気的構成を示すブロック図である。 <2.2. Detailed Configuration of Protective Case>
FIG. 5 is a block diagram showing the electrical configuration of the protective case 30. As shown in FIG.
　４つの保護ケース３０は、それぞれ、保護ケース制御部３１、制限信号入力部３２、近距離無線受信部３３、長距離無線送信部３４、長距離無線受信部３５、ケース間通信部３６、および警告部３７を有している。制限信号入力部３２、近距離無線受信部３３、長距離無線送信部３４、長距離無線受信部３５、ケース間通信部３６、および警告部３７は、それぞれ保護ケース制御部３１に接続される。ただし、制限信号入力部３２、近距離無線受信部３３、長距離無線送信部３４、長距離無線受信部３５、およびケース間通信部３６は、保護ケース制御部３１に含まれていてもよい。 Each of the four protection cases 30 includes a protection case control unit 31, a restriction signal input unit 32, a short distance wireless reception unit 33, a long distance wireless transmission unit 34, a long distance wireless reception unit 35, an inter-case communication unit 36, and a warning. It has a part 37. The restriction signal input unit 32, the short distance wireless reception unit 33, the long distance wireless transmission unit 34, the long distance wireless reception unit 35, the inter-case communication unit 36, and the warning unit 37 are connected to the protective case control unit 31. However, the restriction signal input unit 32, the short distance wireless reception unit 33, the long distance wireless transmission unit 34, the long distance wireless reception unit 35, and the inter-case communication unit 36 may be included in the protection case control unit 31.
　制限信号入力部３２は、保護ケース３０が取り付けられているスマートフォン１０へ、後述する制限信号を入力する。制限信号は、制限信号入力部３２から、例えばスマートフォン１０のＵＳＢポートを介して、スマートフォン１０へ入力される。また、近距離無線受信部３３は、端末ホルダ２０から、近距離無線信号である上述の端末特定信号を受信する。 The restriction signal input unit 32 inputs a restriction signal to be described later to the smartphone 10 to which the protective case 30 is attached. The restriction signal is input from the restriction signal input unit 32 to the smartphone 10 via, for example, the USB port of the smartphone 10. In addition, the short distance wireless reception unit 33 receives the above-mentioned terminal identification signal, which is a short distance wireless signal, from the terminal holder 20.
　長距離無線送信部３４は、上述の外部装置２００に対して、長距離無線信号を送信する。また、長距離無線受信部３５は、上述の背面検出部４０から、長距離無線信号を受信する。なお、長距離無線信号を用いる長距離無線通信には、例えば、Ｗｉ‐ＳＵＮ（Ｗｉｒｅｌｅｓｓ　Ｓｍａｒｔ　Ｕｔｉｌｉｔｙ　Ｎｅｔｗｏｒｋ）規格が用いられる。長距離無線送信部３４および長距離無線受信部３５の動作については、詳細な説明を後述する。 The long distance wireless transmission unit 34 transmits a long distance wireless signal to the external device 200 described above. Further, the long distance wireless reception unit 35 receives a long distance wireless signal from the above-described back surface detection unit 40. For long distance wireless communication using long distance wireless signals, for example, the Wi-SUN (Wireless Smart Utility Network) standard is used. The operations of the long distance wireless transmission unit 34 and the long distance wireless reception unit 35 will be described in detail later.
　ケース間通信部３６は、他の保護ケース３０と、近距離無線通信を行う。当該他の保護ケース３０との近距離無線通信に用いられる近距離無線信号は、赤外線であってもよいし、Ｂｌｕｅｔｏｏｔｈ（登録商標）であってもよい。 The inter-case communication unit 36 performs near field communication with another protective case 30. A near-field wireless signal used for near-field wireless communication with the other protective case 30 may be infrared or Bluetooth (registered trademark).
　警告部３７は、保護ケース３０の表面に固定されたＬＥＤランプ（図３参照）を有する。ただし、警告部３７は、警告音を発するホーンが内蔵された電子音報知器を有してもよい。また、警告部３７は、文字を表示可能なモニターを有してもよい。 The warning unit 37 has an LED lamp (see FIG. 3) fixed to the surface of the protective case 30. However, the warning unit 37 may have an electronic sound alarm in which a horn that emits a warning sound is incorporated. The warning unit 37 may also have a monitor capable of displaying characters.
　保護ケース制御部３１は、スマートフォン１０と電気的に接続され、マイコンを含み、予めメモリなどに書き込まれたプログラムを実行し、接続される各部を駆動制御する。保護ケース制御部３１は、操作制限システム２の中で、端末ホルダ２０に最も近いスマートフォン１０を特定する「端末特定部」として機能する。また、保護ケース制御部３１は、操作制限システム２の中で、スマートフォン１０のＯＳ１１と合わせて、特定されたスマートフォン１０の操作を制限する「操作制限部」として機能する。さらに、保護ケース制御部３１は、運転管理システム３の中で、車両１００の周囲の各部との通信等を行う「運転管理部」として機能する。 The protective case control unit 31 is electrically connected to the smartphone 10, includes a microcomputer, executes a program written in advance in a memory or the like, and drives and controls each connected unit. The protection case control unit 31 functions as a “terminal identification unit” that identifies the smartphone 10 closest to the terminal holder 20 in the operation restriction system 2. Further, the protection case control unit 31 functions as an “operation restriction unit” that restricts the operation of the specified smartphone 10 in the operation restriction system 2 together with the OS 11 of the smartphone 10. Furthermore, in the drive management system 3, the protective case control unit 31 functions as a "drive management unit" that communicates with each part around the vehicle 100.
　まず、「端末特定部」としての機能について説明する。保護ケース制御部３１は、近距離無線受信部３３が受信する端末特定信号の信号強度を検出する。他の保護ケース３０においても、端末特定信号を受信し、受信した端末特定信号の信号強度を検出する。各保護ケース制御部３１は、他の保護ケース３０と、ケース間通信部３６を介して、互いに他の保護ケース３０で検出した信号強度に係る情報をやりとりする。保護ケース制御部３１は、自身が検出した信号強度と、他の保護ケース３０が検出した信号強度とを比較した結果に基づいて、最も強い信号強度を検出した保護ケース３０を割り出す。そして、保護ケース制御部３１は、割り出した保護ケース３０が取り付けられているスマートフォン１０を、端末ホルダ２０に最も近いスマートフォン１０として特定する。すなわち、割り出した保護ケース３０が取り付けられているスマートフォン１０は、運転者が保有するスマートフォンであると判定する。 First, the function as the "terminal identification unit" will be described. The protective case control unit 31 detects the signal strength of the terminal identification signal received by the short distance wireless reception unit 33. Also in the other protective case 30, the terminal identification signal is received, and the signal strength of the received terminal identification signal is detected. Each protection case control unit 31 exchanges information related to the signal strength detected by the other protection case 30 with each other via the other protection case 30 and the inter-case communication unit 36. The protective case control unit 31 determines the protective case 30 that has detected the strongest signal strength based on the result of comparing the signal strength detected by itself with the signal strength detected by the other protective cases 30. Then, the protective case control unit 31 specifies the smartphone 10 to which the indexed protective case 30 is attached as the smartphone 10 closest to the terminal holder 20. That is, it is determined that the smartphone 10 to which the indexed protective case 30 is attached is a smartphone owned by the driver.
　そして、保護ケース制御部３１は、特定したスマートフォン１０に対して、制限信号入力部３２を介して、そのスマートフォン１０が受け付けるユーザの操作を制限または無効にする制限信号を入力する。これにより、運転者による、スマートフォン１０の使用を制限できる。 Then, the protective case control unit 31 inputs a restriction signal for restricting or invalidating the user's operation received by the smartphone 10 to the specified smartphone 10 via the restriction signal input unit 32. Thereby, the driver's use of the smartphone 10 can be restricted.
　なお、保護ケース制御部３１における端末特定信号の信号強度を比較する処理は、４つの保護ケース３０のうち、予め決められた一の保護ケース３０で行われてもよいし、４つの保護ケース３０それぞれで行われてもよい。一の保護ケース３０で信号強度を比較する場合、４つの保護ケース３０それぞれは、決められた一の保護ケース３０に対して、信号強度に係る情報を送信する。そして、その一の保護ケース３０において、信号強度が比較され、最も強い信号強度を検出した保護ケース３０が割り出され、運転者のスマートフォン１０が特定される。 The process of comparing the signal strengths of the terminal identification signals in the protective case control unit 31 may be performed in one of the four protective cases 30 which is determined in advance, or four protective cases 30. Each may be performed. When signal strengths are compared in one protection case 30, each of the four protection cases 30 transmits information related to the signal strength to the determined one protection case 30. Then, in the one protective case 30, the signal strengths are compared, the protective case 30 that detects the strongest signal strength is identified, and the driver's smartphone 10 is identified.
　また、４つの保護ケース３０それぞれで信号強度を比較する場合、４つの保護ケース３０は、他の保護ケース３０それぞれに対し、検出した信号強度に係る情報を送信する。この場合において、保護ケース制御部３１が特定したスマートフォン１０が、自身の保護ケース３０が取り付けられたスマートフォン１０である場合、保護ケース制御部３１は、自身の保護ケース３０が取り付けられたスマートフォン１０が受け付けるユーザの操作を制限または無効にすればよく、他の保護ケース３０が取り付けられたスマートフォン１０に対して、制限信号を入力する必要がない。 When signal strengths are compared in each of the four protective cases 30, the four protective cases 30 transmit information related to the detected signal strength to each of the other protective cases 30. In this case, when the smartphone 10 specified by the protection case control unit 31 is the smartphone 10 to which the protection case 30 of its own is attached, the smartphone 10 to which the protection case 30 of its own is attached is the protection case control unit 31. The user's operation to be received may be restricted or invalidated, and there is no need to input a restriction signal to the smartphone 10 to which the other protective case 30 is attached.
　「操作制限部」としての機能および「運転管理部」としての機能については、詳細な説明を後述する。 A detailed description of the function as the "operation restriction unit" and the function as the "operation management unit" will be described later.
　＜２．３．スマートフォンの詳細な構成＞
　図６は、スマートフォン１０の電気的構成を示すブロック図である。 <2.3. Detailed Configuration of Smartphone>
FIG. 6 is a block diagram showing the electrical configuration of the smartphone 10.
　スマートフォン１０は、ＯＳ１１、データ通信部１２、ＯＳ制限信号受信部１３、ディスプレイ１４、およびジャック１５を有している。データ通信部１２、ＯＳ１１、ディスプレイ１４、およびジャック１５は、それぞれＯＳ１１に接続される。ただし、データ通信部１２およびＯＳ制限信号受信部１３は、ＯＳ１１に含まれていてもよい。 The smartphone 10 has an OS 11, a data communication unit 12, an OS restriction signal reception unit 13, a display 14, and a jack 15. The data communication unit 12, the OS 11, the display 14, and the jack 15 are connected to the OS 11, respectively. However, the data communication unit 12 and the OS restriction signal reception unit 13 may be included in the OS 11.
　データ通信部１２は、他のスマートフォン１０またはパソコンとのメールのやり取り、およびウェブサイトへの接続等の機能を実行するための、通信手段である。 The data communication unit 12 is a communication means for executing functions such as exchange of mail with another smartphone 10 or a personal computer and connection to a website.
　ＯＳ制限信号受信部１３は、保護ケース３０から制限信号入力部３２を介して入力される制限信号を受信する、受信手段である。 The OS restriction signal reception unit 13 is a reception unit that receives a restriction signal input from the protection case 30 via the restriction signal input unit 32.
　ディスプレイ１４は、スマートフォン１０の表面に設けられる、ホーム画面等を表示する一般的な画面である。 The display 14 is a general screen provided on the surface of the smartphone 10 to display a home screen and the like.
　ジャック１５は、端末ホルダ２０の接続プラグ２２に接続される部位である。これにより、スマートフォン１０は、端末ホルダ２０と電気的に接続される。スマートフォン１０は、接続プラグ２２およびジャック１５を介して、端末ホルダ２０から電力が供給される。 The jack 15 is a portion connected to the connection plug 22 of the terminal holder 20. Thus, the smartphone 10 is electrically connected to the terminal holder 20. The smartphone 10 is supplied with power from the terminal holder 20 via the connection plug 22 and the jack 15.
　ＯＳ１１は、マイコンを含み、予めメモリなどに書き込まれたプログラムを実行し、スマートフォン１０の各種機能を実行する。また、上述のとおり、ＯＳ１１は、保護ケース３０と合わせて、特定されたスマートフォン１０の操作を制限する「操作制限部」として機能する。「操作制限部」として機能は、ＯＳ１１のメモリにインストールされたアプリケーションソフトウエアにより、実現される。 The OS 11 includes a microcomputer, executes a program written in advance in a memory or the like, and executes various functions of the smartphone 10. In addition, as described above, the OS 11 functions as an “operation restriction unit” that restricts the operation of the specified smartphone 10 in combination with the protective case 30. The function as the "operation restriction unit" is realized by application software installed in the memory of the OS 11.
　続いて、当該「操作制限部」としての機能について説明する。ＯＳ制限信号受信部１３が、上述の制限信号を受信した場合、当該スマートフォン１０は、自身のスマートフォン１０が受け付けるユーザの操作を制限または無効にする制御を行う。ユーザの操作の制限または無効は、例えば、スマートフォン１０のディスプレイ１４の表示を、ホーム画面に強制的に切り替えることで実現される。 Then, the function as the said "operation restriction | limiting part" is demonstrated. When the OS restriction signal receiving unit 13 receives the above-described restriction signal, the smartphone 10 performs control to restrict or invalidate the user's operation received by the smartphone 10 of the own. The restriction or invalidation of the user's operation is realized, for example, by forcibly switching the display of the display 14 of the smartphone 10 to the home screen.
　図７は、ユーザの操作を制限または無効にする方法を説明するための図である。図７では、スマートフォン１０のディスプレイ１４に表示される画面の遷移を示している。 FIG. 7 is a diagram for describing a method of restricting or disabling the user's operation. FIG. 7 shows the transition of the screen displayed on the display 14 of the smartphone 10.
　スマートフォン１０のディスプレイ１４には、操作受付待ち状態では、ホーム画面が表示される（図７（Ａ））。ホーム画面には、アプリケーションに関連付けられた複数のアイコン画像が表示される。そして、ホーム画面に対するユーザの操作を受け付けると、ホーム画面はアプリケーション画面に切り替えられる。例えば、このホーム画面において、ユーザが、例えば、「Ｍａｉｌ」のアイコン画像をタッチすると、スマートフォン１０は、メール用のアプリケーション画面に切り替えられる（図７（Ｂ））。しかし、スマートフォン１０は、操作を制限または無効にする制御が実行されていると、ディスプレイ１４の表示を、アプリケーション画面からホーム画面に強制的に切り替える（図７（Ｃ））。つまり、ユーザがホーム画面から操作して、アプリケーション画面が表示されても、すぐにホーム画面に戻るため、ユーザは、スマートフォン１０を操作することができない。 The home screen is displayed on the display 14 of the smartphone 10 while waiting for an operation reception (FIG. 7A). The home screen displays a plurality of icon images associated with the application. Then, when the user's operation on the home screen is accepted, the home screen is switched to the application screen. For example, when the user touches, for example, the icon image of “Mail” on this home screen, the smartphone 10 is switched to the application screen for mail (FIG. 7 (B)). However, the smartphone 10 forcibly switches the display of the display 14 from the application screen to the home screen when control to restrict or invalidate the operation is executed (FIG. 7 (C)). That is, even if the user operates from the home screen and the application screen is displayed, the user can not operate the smartphone 10 because the user immediately returns to the home screen.
　＜２．４．背面検出部の詳細な構成＞
　図８は、背面検出部４０の電気的構成を示すブロック図である。 <2.4. Detailed Configuration of Rear Detection Unit>
FIG. 8 is a block diagram showing an electrical configuration of the back surface detection unit 40. As shown in FIG.
　背面検出部４０は、背面検出制御部４１、背面検出センサ４２、および背面検出送信部４３を有している。背面検出センサ４２および背面検出送信部４３は、それぞれ背面検出制御部４１に接続される。ただし、背面検出送信部４３は、背面検出制御部４１に含まれていてもよい。 The back surface detection unit 40 includes a back surface detection control unit 41, a back surface detection sensor 42, and a back surface detection transmission unit 43. The back surface detection sensor 42 and the back surface detection transmission unit 43 are connected to the back surface detection control unit 41, respectively. However, the back surface detection transmission unit 43 may be included in the back surface detection control unit 41.
　背面検出センサ４２には、例えば、超音波を利用した測距センサが用いられる。背面検出センサ４２は、車両１００の背面に固定される。そして、背面検出センサ４２は、例えば、車両１００の背面と後続の車両との車間距離、または、車両１００の後退時の車庫の壁との接近距離等を計測する。つまり、背面検出センサ４２は、車両１００とは別の車両（例えば、後続の車両）、通行人、ガードレール、または車庫の壁等を含む「車両１００とは別の物体」と車両１００との離隔を計測する。そして、背面検出制御部４１は、背面検出センサ４２の計測結果に基づき、当該「車両１００とは別の物体」と車両１００との接近を検知する。 For example, a distance measuring sensor using an ultrasonic wave is used as the back surface detection sensor 42. The back surface detection sensor 42 is fixed to the back surface of the vehicle 100. Then, the back surface detection sensor 42 measures, for example, an inter-vehicle distance between the back surface of the vehicle 100 and the following vehicle, an approach distance with a wall of a garage when the vehicle 100 moves backward, and the like. That is, the back surface detection sensor 42 separates the vehicle 100 from an “object different from the vehicle 100” including a vehicle different from the vehicle 100 (for example, a subsequent vehicle), a passerby, a guardrail, or a wall of a garage. Measure Then, based on the measurement result of the back surface detection sensor 42, the back surface detection control unit 41 detects the approach between the “object different from the vehicle 100” and the vehicle 100.
　背面検出部４０は、当該「車両１００とは別の物体」と車両１００との接近を検知した場合に、背面検出送信部４３を介して、保護ケース３０の後述する保護ケース制御部３１へ、長距離無線信号である背面検知信号を送信する。背面検出部４０から送信された背面検知信号は、長距離無線通信によって、保護ケース３０の長距離無線受信部３５を介して受信される。重複するが、長距離無線通信には、例えば、Ｗｉ‐ＳＵＮ（Ｗｉｒｅｌｅｓｓ　Ｓｍａｒｔ　Ｕｔｉｌｉｔｙ　Ｎｅｔｗｏｒｋ）規格が用いられる。これにより、背面検出部４０と保護ケース３０とが数メートル以上離れている場合でも、通信時のノイズが低減され、より正確に伝達される。さらに、保護ケース３０は、背面検知信号を受信した場合に、さらに警告部３７において警告動作を行う。 When the back surface detection unit 40 detects an approach between the “object different from the vehicle 100” and the vehicle 100, the back surface detection unit 40 sends the protection case control unit 31 described later of the protection case 30 via the back surface detection transmission unit 43. Transmit a back side detection signal which is a long distance radio signal. The back surface detection signal transmitted from the back surface detection unit 40 is received via the long distance wireless reception unit 35 of the protective case 30 by long distance wireless communication. Although overlapping, for example, Wi-SUN (Wireless Smart Utility Network) standard is used for long distance wireless communication. Thereby, even when the back surface detection unit 40 and the protective case 30 are separated by several meters or more, noise during communication is reduced and transmitted more accurately. Furthermore, when the protection case 30 receives the back surface detection signal, the warning unit 37 further performs a warning operation.
　＜３．各システムの処理工程＞
　＜３．１．操作制限システムでの処理＞
　図９は、操作制限システム２で実行される処理のフローチャートである。図９では、端末ホルダ２０と、保護ケース３０と、スマートフォン１０とのそれぞれで実行される処理を、併記している。 <3. Processing process of each system>
<3.1. Processing in the operation restriction system>
FIG. 9 is a flowchart of processing executed by the operation restriction system 2. In FIG. 9, the process performed by each of the terminal holder 20, the protective case 30, and the smartphone 10 is described.
　端末ホルダ２０の端末ホルダ制御部２１は、例えば、端末ホルダ２０が車両１００から電力が供給されたタイミングで起動される。端末ホルダ制御部２１は、加速度検出部２５が検出した加速度を取得する（ステップＳ１）。端末ホルダ制御部２１は、取得した加速度が所定値以上であるか否かを判定する（ステップＳ２）。端末ホルダ制御部２１は、加速度が所定値以上であるか否かにより、停車中の車両１００が発進したか否かを判定する。 The terminal holder control unit 21 of the terminal holder 20 is activated, for example, at a timing when the terminal holder 20 is supplied with power from the vehicle 100. The terminal holder control unit 21 acquires the acceleration detected by the acceleration detection unit 25 (step S1). The terminal holder control unit 21 determines whether the acquired acceleration is equal to or more than a predetermined value (step S2). The terminal holder control unit 21 determines whether the stopped vehicle 100 has started by whether the acceleration is equal to or more than a predetermined value.
　所定値以上でない場合（ステップＳ２：ＮＯ）、端末ホルダ制御部２１は、車両１００は停車していると判定し、ステップＳ１の処理に戻る。つまり、車両１００の停車中は、スマートフォン１０の使用が制限されない。 When it is not more than predetermined value (Step S2: NO), terminal holder control part 21 judges with vehicles 100 having stopped, and returns to processing of Step S1. That is, use of the smartphone 10 is not restricted while the vehicle 100 is stopped.
　所定値以上である場合（ステップＳ２：ＹＥＳ）、端末ホルダ制御部２１は、車両１００が発進したと判定し、特定信号発信部２４を介して、端末特定信号を出力する（ステップＳ３）。上述のとおり、この端末特定信号は、端末ホルダ２０と、４つのスマートフォン１０それぞれとの相対距離を比較するための近距離無線信号である。この場合、停車中にはスマートフォン１０が使用できても、車両１００が発進するときには、運転者のスマートフォン１０の使用を制限できる。なお、端末ホルダ制御部２１は、ステップＳ３以降、端末特定信号を出力し続けてもよいし、一定時間経過後、端末特定信号の出力を停止してもよい。 If it is equal to or greater than the predetermined value (step S2: YES), the terminal holder control unit 21 determines that the vehicle 100 has started, and outputs a terminal identification signal via the identification signal transmitting unit 24 (step S3). As described above, this terminal identification signal is a short distance wireless signal for comparing the relative distance between the terminal holder 20 and each of the four smartphones 10. In this case, even if the smartphone 10 can be used while the vehicle is stopped, the use of the smartphone 10 by the driver can be restricted when the vehicle 100 starts moving. The terminal holder control unit 21 may continue to output the terminal identification signal after step S3 or may stop the output of the terminal identification signal after a predetermined time has elapsed.
　各保護ケース３０の保護ケース制御部３１は、端末ホルダ２０から発せされた端末特定信号を受信したか否かを判定する（ステップＳ４）。受信しない場合（ステップＳ４：ＮＯ）、保護ケース制御部３１は、ステップＳ４の処理を繰り返す。端末特定信号を受信した場合（ステップＳ４：ＹＥＳ）、保護ケース制御部３１は、受信した端末特定信号の信号強度を検出する（ステップＳ５）。 The protection case control unit 31 of each protection case 30 determines whether or not the terminal identification signal issued from the terminal holder 20 has been received (step S4). If not received (step S4: NO), the protective case control unit 31 repeats the process of step S4. When the terminal identification signal is received (step S4: YES), the protection case control unit 31 detects the signal strength of the received terminal identification signal (step S5).
　保護ケース制御部３１は、検出した信号強度を、ケース間通信部３６を介して、他の保護ケース３０で検出した信号強度と比較する（ステップＳ６）。このとき、保護ケース制御部３１は、上述のとおり、他の保護ケース３０に対し、ケース間通信部３６を介して、検出した信号強度に係る情報を出力し、他のスマートフォン１０で信号強度の比較処理が行われてもよい。 The protective case control unit 31 compares the detected signal strength with the signal strength detected in another protective case 30 via the inter-case communication unit 36 (step S6). At this time, as described above, the protective case control unit 31 outputs the information related to the detected signal strength to the other protective cases 30 via the inter-case communication unit 36, and A comparison process may be performed.
　保護ケース制御部３１は、信号強度を比較した結果、最も強い信号強度を検出した保護ケース３０に取り付けられているスマートフォン１０を、運転者が保有するスマートフォンとして特定する（ステップＳ７）。そして、保護ケース制御部３１は、そのスマートフォン１０に対し、制限信号入力部３２を介して、そのスマートフォン１０が受け付けるユーザの操作を制限または無効にするための制限信号を入力する（ステップＳ８）。 As a result of comparing the signal strengths, the protective case control unit 31 specifies the smartphone 10 attached to the protective case 30 that has detected the strongest signal strength as a smartphone owned by the driver (step S7). Then, the protective case control unit 31 inputs a restriction signal for restricting or invalidating the operation of the user received by the smartphone 10 to the smartphone 10 via the restriction signal input unit 32 (step S8).
　スマートフォン１０のＯＳ１１は、ＯＳ制限信号受信部１３を介して、保護ケース３０から発せされた制限信号を受信したか否かを判定する（ステップＳ９）。受信しない場合（ステップＳ９：ＮＯ）、ステップＳ９の処理を繰り返す。制限信号を受信した場合（ステップＳ９：ＹＥＳ）、ＯＳ１１は、自身のスマートフォン１０が受け付けるユーザの操作を制限または無効にする制御を行う（ステップＳ１０）。 The OS 11 of the smartphone 10 determines whether or not the restriction signal issued from the protective case 30 has been received via the OS restriction signal receiving unit 13 (step S9). If not received (step S9: NO), the process of step S9 is repeated. When the restriction signal is received (step S9: YES), the OS 11 performs control to restrict or invalidate the operation of the user received by the own smartphone 10 (step S10).
　なお、ユーザの操作が制限または無効にされたスマートフォン１０が、当該制限または無効を解除するタイミングは、特に限定されない。例えば、端末ホルダ２０において、検出する加速度から車両１００の停車を検知すると、解除信号を送信し、保護ケース３０が、端末ホルダ２０からその解除信号を受信したときに、スマートフォン１０に対し、当該制限または無効を解除する解除信号を入力する構成としてもよい。 The timing at which the smartphone 10 whose operation is restricted or invalidated releases the restriction or invalidation is not particularly limited. For example, when the stop of the vehicle 100 is detected from the detected acceleration in the terminal holder 20, a release signal is transmitted, and when the protective case 30 receives the release signal from the terminal holder 20, the restriction is applied to the smartphone 10 Alternatively, it may be configured to input a release signal for releasing the invalidation.
　以上のように、運転席１０１Ａに設置した端末ホルダ２０に最も近いスマートフォン１０を、運転者が保有するスマートフォンとして特定し、そのスマートフォン１０の使用を制限することで、運転者による、スマートフォン１０の使用を制限できる。その結果、運転中の、スマートフォン１０の使用による事故を未然に防ぐことができる。また、車両１００の他の搭乗者のスマートフォン１０は、使用が制限されないため、他の搭乗者は、快適にスマートフォン１０を使用できる。 As described above, the smartphone 10 closest to the terminal holder 20 installed in the driver's seat 101A is specified as the smartphone owned by the driver, and the use of the smartphone 10 is restricted to allow the driver to use the smartphone 10 Can be limited. As a result, it is possible to prevent an accident due to the use of the smartphone 10 while driving. In addition, since the smartphones 10 of other passengers of the vehicle 100 are not restricted in use, the other passengers can use the smartphones 10 comfortably.
　また、加速度から車両１００が停車していると判断されるときには、端末ホルダ２０から無線信号が発せられることはないため、停車中であれば、運転者も、スマートフォン１０を使用することができる。 Further, when it is determined from the acceleration that the vehicle 100 is stopped, the wireless signal is not emitted from the terminal holder 20, so that the driver can also use the smartphone 10 while the vehicle is stopped.
　＜３．２．運転管理システムでの処理＞
　図１０Ａおよび図１０Ｂは、それぞれ、運転管理システム３で実行される処理の一部のフローチャートである。図１０Ａでは、背面検出部４０と、保護ケース３０とのそれぞれで実行される処理を、併記している。図１０Ｂでは、端末ホルダ２０と、保護ケース３０とのそれぞれで実行される処理を、併記している。図１０Ａおよび図１０Ｂに示すとおり、保護ケース３０における上述の「運転管理部」としての機能が実現される。 <3.2. Processing in Operation Management System>
FIGS. 10A and 10B are each a flowchart of a part of the process executed by the operation management system 3. In FIG. 10A, the process performed by each of the back surface detection unit 40 and the protective case 30 is described. In FIG. 10B, the process performed by each of the terminal holder 20 and the protective case 30 is described together. As shown in FIGS. 10A and 10B, the above-described function as the “operation management unit” in the protective case 30 is realized.
　まず、図１０Ａの処理について、説明する。背面検出部４０は、例えば、車両のバッテリーから給電されたタイミングで起動される。背面検出センサ４２は、車両１００とは別の物体と車両１００との離隔を計測する（ステップＳ１１）。背面検出制御部４１は、背面検出センサ４２の計測結果に基づき、車両１００とは別の物体と車両１００との接近を検知する（ステップＳ１２）。車両１００とは別の物体と車両１００との離隔が所定値よりも大きい場合（ステップＳ１２：ＮＯ）、背面検出制御部４１は、車両１００とは別の物体が車両１００に接近していないと判定し、ステップＳ１１の処理に戻る。 First, the process of FIG. 10A will be described. The back surface detection unit 40 is activated, for example, at a timing when power is supplied from the battery of the vehicle. The back surface detection sensor 42 measures the distance between the vehicle 100 and an object different from the vehicle 100 (step S11). The back surface detection control unit 41 detects an approach between the vehicle 100 and an object other than the vehicle 100 based on the measurement result of the back surface detection sensor 42 (step S12). When the separation between an object different from the vehicle 100 and the vehicle 100 is larger than a predetermined value (step S12: NO), the back surface detection control unit 41 determines that an object different from the vehicle 100 is not approaching the vehicle 100. It determines and returns to the process of step S11.
　車両１００とは別の物体と車両１００との離隔が所定値以下である場合（ステップＳ１２：ＹＥＳ）、背面検出制御部４１は、車両１００とは別の物体が車両１００に接近していると判定し、背面検出送信部４３を介して、保護ケース３０へ、長距離無線信号である背面検知信号を出力する（ステップＳ１３）。なお、背面検出制御部４１は、背面検出センサ４２によるその後の計測結果に基づき、車両１００とは別の物体と車両１００との離隔が所定値よりも大きくなったと判定するまで、継続して背面検知信号を出力する。 When the separation between the object different from the vehicle 100 and the vehicle 100 is equal to or less than the predetermined value (step S12: YES), the back surface detection control unit 41 determines that the object different from the vehicle 100 is approaching the vehicle 100. It judges and outputs the back detection signal which is a long distance radio signal to protection case 30 via back detection transmission section 43 (Step S13). The back surface detection control unit 41 continues the back surface until it is determined that the distance between the vehicle 100 and an object different from the vehicle 100 is larger than a predetermined value, based on the subsequent measurement result by the back surface detection sensor 42. Output a detection signal.
　保護ケース３０の保護ケース制御部３１は、長距離無線受信部３５を介して、背面検知信号を受信したか否かを判定する（ステップＳ１４）。受信しない場合（ステップＳ１４：ＮＯ）、保護ケース制御部３１は、ステップＳ１４の処理を繰り返す。背面検知信号を受信した場合（ステップＳ１４：ＹＥＳ）、保護ケース制御部３１は、警告部３７を介して警告動作を行う（ステップＳ１５）。これにより、運転者は、車両１００とは別の物体が車両１００に接近していることに気づき、車両１００を停車させるなどの対策を行うことができる。この結果、これらが接触する事故を未然に防ぐことができる。 The protection case control unit 31 of the protection case 30 determines whether or not the back surface detection signal has been received via the long distance wireless reception unit 35 (step S14). If not received (step S14: NO), the protective case control unit 31 repeats the process of step S14. When the back surface detection signal is received (step S14: YES), the protective case control unit 31 performs a warning operation via the warning unit 37 (step S15). As a result, the driver notices that an object different from the vehicle 100 is approaching the vehicle 100, and can take measures such as stopping the vehicle 100. As a result, the accident which these contact can be prevented beforehand.
　次に、図１０Ｂの処理について、説明する。図１０ＢにおけるステップＳ２１～ステップＳ２４については、図９におけるステップＳ１～ステップＳ４と同等の工程を有するため、重複説明を省略する。ステップＳ２４において、端末特定信号を受信したと判定した場合（ステップＳ２４：ＹＥＳ）、保護ケース制御部３１は、「保護ケース制御部３１が端末特定信号を受信した事実」および「保護ケース制御部３１が端末特定信号を受信した時間」にかかる信号を、長距離無線送信部３４を介して、車両１００の外部装置２００へ送信する（ステップＳ２５）。これにより、車両１００の外部から車両１００の駆動状態を把握することができる。この結果、車両１００の運行状況、さらには運転者の勤務状況の把握につなげることができる。なお、重複するが、長距離無線通信には、例えば、Ｗｉ‐ＳＵＮ（Ｗｉｒｅｌｅｓｓ　Ｓｍａｒｔ　Ｕｔｉｌｉｔｙ　Ｎｅｔｗｏｒｋ）規格が用いられる。これにより、保護ケース３０と外部装置２００とが数メートル以上離れている場合でも、通信時のノイズが低減され、より正確に伝達される。 Next, the process of FIG. 10B will be described. Steps S21 to S24 in FIG. 10B have the same processes as steps S1 to S4 in FIG. If it is determined in step S24 that the terminal identification signal has been received (step S24: YES), the protective case control unit 31 determines that “the protection case control unit 31 has received the terminal identification signal” and “the protection case control unit 31 A signal relating to the time when the terminal identification signal is received is transmitted to the external device 200 of the vehicle 100 via the long distance wireless transmission unit 34 (step S25). Thus, the driving state of the vehicle 100 can be grasped from the outside of the vehicle 100. As a result, it is possible to grasp the operation status of the vehicle 100 and further the driver's work status. Although redundant, for example, Wi-SUN (Wireless Smart Utility Network) standard is used for long distance wireless communication. As a result, even when the protective case 30 and the external device 200 are separated by several meters or more, noise during communication is reduced and transmitted more accurately.
　＜４．変形例＞
　以上、本発明の主たる実施形態について説明したが、本発明は、上述の実施形態に限定されるものではない。 <4. Modified example>
As mentioned above, although the main embodiment of the present invention was described, the present invention is not limited to the above-mentioned embodiment.
　上述の実施形態では、端末ホルダ２０は、運転席１０１Ａ近傍に配置されるが、運転席１０１Ａと、助手席１０１Ｂの間に配置されることもある。この場合、端末ホルダ２０は、２つの特定信号発信部を有することが好ましい。図１１は、２つの特定信号発信部２４Ａ，２４Ｂが設けられた端末ホルダ２０を示す図である。特定信号発信部２４Ａは、端末ホルダ２０の運転席１０１Ａ側端部に設けられ、特定信号発信部２４Ｂは、端末ホルダ２０の助手席１０１Ｂ側端部に設けられる。この場合、保護ケース３０は、特定信号発信部２４Ａ，２４Ｂのいずれから受信した無線信号の信号強度が強いかを判定する。特定信号発信部２４Ａから受信した無線信号の信号強度が強い場合、その保護ケース３０が取り付けられたスマートフォン１０は、運転者が保有するスマートフォンであると判定する。一方、特定信号発信部２４Ｂから受信した無線信号の信号強度が強い場合、その保護ケース３０が取り付けられたスマートフォン１０は、助手席者が保有するスマートフォンであると判定する。 In the above-mentioned embodiment, although terminal holder 20 is arranged near driver's seat 101A, it may be arranged between driver's seat 101A and assistant passenger's seat 101B. In this case, the terminal holder 20 preferably has two specific signal transmitters. FIG. 11 is a view showing the terminal holder 20 provided with two specific signal transmitting units 24A and 24B. The specific signal transmitting unit 24A is provided at the driver seat 101A side end of the terminal holder 20, and the specific signal transmitting unit 24B is provided at the passenger seat 101B side end of the terminal holder 20. In this case, the protective case 30 determines which one of the specific signal transmitting units 24A and 24B the signal strength of the radio signal received from is strong. When the signal strength of the wireless signal received from the specific signal transmission unit 24A is strong, it is determined that the smartphone 10 to which the protective case 30 is attached is a smartphone owned by the driver. On the other hand, when the signal strength of the wireless signal received from the specific signal transmitting unit 24B is strong, it is determined that the smartphone 10 to which the protective case 30 is attached is a smartphone owned by the passenger.
　さらに、端末ホルダ２０は、スマートフォン１０が装着されている場合には、端末特定信号を発せず、装着されたスマートフォン１０に対して、ユーザの操作の制限または無効にする制御を行うようにしてもよい。 Furthermore, even when the smartphone 10 is attached, the terminal holder 20 does not emit a terminal identification signal, and performs control to restrict or invalidate the user's operation to the attached smartphone 10. Good.
　上述の実施形態では、４つのスマートフォン１０と、当該４つのスマートフォン１０にそれぞれ取り付けられた４つの保護ケース３０が用いられていた。しかし、これらの数は、４つに限定されない。スマートフォン１０および保護ケース３０の数は、１つであってもよく、２以上の複数のいかなる値であってもよい。 In the above-described embodiment, four smartphones 10 and four protective cases 30 attached to the four smartphones 10 are used. However, these numbers are not limited to four. The number of smartphones 10 and protective cases 30 may be one, or any number of two or more.
　また、上述の実施形態では、無線信号を出力する「発信器」の一例として、発信機能および加速度検出機能を有し、かつ、スマートフォンを保持することが可能な「端末ホルダ２０」を挙げて説明したが、これに限定されない。「発信器」は、運転席１０１Ａに設置され、運転席１０１Ａの位置を特定できる機器であればよい。図１２は、発信器の別の例を示す図である。例えば、「発信器」は、図１２に示すように、キーホルダー５０であってもよい。この場合、キーホルダー５０の筐体５１に、図４で説明した、制御部、加速度検出部、特定信号発信部が設けられる。そして、キーホルダー５０のチェーンロック５２に車両用キーを取り付けることで、「発信器」は、運転時には常に運転席１０１Ａに配置されるようになる。また、「発信器」は、車両用キーに内蔵されていてもよい。 Moreover, in the above-mentioned embodiment, the "terminal holder 20" which has a transmission function and an acceleration detection function and can hold a smart phone is mentioned as an example of the "transmitter" which outputs a radio signal, and is demonstrated. However, it is not limited to this. The “transmitter” may be any device installed in the driver's seat 101A and capable of specifying the position of the driver's seat 101A. FIG. 12 is a diagram showing another example of the transmitter. For example, the “transmitter” may be a key holder 50 as shown in FIG. In this case, the control unit, the acceleration detection unit, and the specific signal transmission unit described in FIG. 4 are provided in the housing 51 of the key holder 50. Then, by attaching the vehicle key to the chain lock 52 of the key holder 50, the “transmitter” is always disposed on the driver's seat 101A at the time of driving. Also, the "transmitter" may be incorporated in the vehicle key.
　また、上述の形態では、端末ホルダ２０が無線信号を発し、スマートフォン１０が取り付けられた保護ケース３０で無線信号の信号強度を検出する構成としているが、これに限定されない。各スマートフォン１０が取り付けられた保護ケース３０から無線信号を出力し、端末ホルダ２０で、当該無線信号の信号強度を検出するようにしてもよい。この場合、端末ホルダ２０が、運転者のスマートフォン１０を特定し、特定したスマートフォン１０の保護ケース３０に対して、制限信号の出力を指示する。 Moreover, in the above-mentioned form, although the terminal holder 20 emits a wireless signal and it is set as the structure which detects the signal strength of a wireless signal with the protective case 30 to which the smart phone 10 was attached, it is not limited to this. A wireless signal may be output from the protective case 30 to which each smartphone 10 is attached, and the terminal holder 20 may detect the signal strength of the wireless signal. In this case, the terminal holder 20 identifies the smartphone 10 of the driver, and instructs the protective case 30 of the identified smartphone 10 to output a limitation signal.
　また、上述の実施形態では、端末ホルダ２０は、加速度から車両１００の発進を判定しているが、これに限定されない。例えば、端末ホルダ２０は振動センサを有し、一定時間振動を検知すると、無線信号を出力するようにしてもよい。 Moreover, in the above-mentioned embodiment, although the terminal holder 20 determines the start of the vehicle 100 from acceleration, it is not limited to this. For example, the terminal holder 20 may have a vibration sensor, and may output a wireless signal when the vibration is detected for a predetermined time.
　また、上述の実施形態では、端末ホルダ２０は、車両１００の加速度が所定値以上であると判断した場合に、保護ケース制御部３１へ無線信号を送信していたが、これに限定されない。端末ホルダ２０は、加速度に関係なく所定の条件を満たしたときに、保護ケース制御部３１へ無線信号を送信するように構成されていてもよい。 Further, in the above-described embodiment, the terminal holder 20 transmits the wireless signal to the protective case control unit 31 when it is determined that the acceleration of the vehicle 100 is equal to or higher than a predetermined value, but is not limited thereto. The terminal holder 20 may be configured to transmit a wireless signal to the protective case control unit 31 when a predetermined condition is satisfied regardless of the acceleration.
　また、上述の実施形態では、携帯情報端末におけるユーザの操作を制限または無効にする方法として、ホーム画面に強制的に切り替えているが、これ以外であってもよい。例えば、スマートフォン１０の電源を強制的にオフにしてもよい。 Moreover, in the above-mentioned embodiment, although it switches forcibly to a home screen as a method of restricting or invalidating the user's operation in a portable information terminal, it may be other than this. For example, the power supply of the smartphone 10 may be forcibly turned off.
　また、保護ケース３０は、車両１００の加速度および別の物体による車両１００への接近に関する情報に加え、さまざまな情報を収集し、外部装置２００へ伝達する手段としての役割を担ってもよい。例えば、保護ケース３０は、運転者のスマートフォン１０に接近したスマートフォンの数をカウントして、外部装置２００へ伝達してもよい。この仕組みを、例えば、バスの中に適用することで、運転者の側を通る乗降客の人数を外部から把握することができる。 In addition to the information on the acceleration of the vehicle 100 and the approach of the vehicle 100 by another object, the protective case 30 may also serve as a means for collecting various information and transmitting it to the external device 200. For example, the protective case 30 may count the number of smartphones approaching the smartphone 10 of the driver and transmit the number to the external device 200. By applying this mechanism to, for example, a bus, it is possible to grasp the number of passengers passing the driver's side from the outside.
　さらに、上述の情報通信システム１は、車両以外に適用されてもよい。そして、携帯情報端末に取り付けられる保護ケースは、当該携帯情報端末と電気的に接続される制御部を有し、当該制御部は、外部の発信器から所定の無線信号を受信すると、携帯情報端末の操作を制限または無効にする制限信号を携帯情報端末へ入力するように構成されていてもよい。 Furthermore, the above-mentioned information communication system 1 may be applied other than a vehicle. The protective case attached to the portable information terminal has a control unit electrically connected to the portable information terminal, and when the control unit receives a predetermined wireless signal from an external transmitter, the portable information terminal May be configured to input a restriction signal to the portable information terminal to restrict or invalidate the operation of the portable information terminal.
　その他、上述の実施形態および変形例に登場した各要素を、矛盾が生じない範囲で、適宜に組み合わせてもよい。 In addition, each element appearing in the above-described embodiment and modification may be combined as appropriate as long as no contradiction occurs.
