本発明の実施形態に係る車両通信システムを図１に示す。車両通信システムは、車両１に搭載され、外部と通信を行う通信機２と、ユーザに携帯され、通信機２と無線通信を行う携帯端末３とによって構成される。 A vehicle communication system according to an embodiment of the present invention is shown in FIG. The vehicle communication system includes a communication device 2 that is mounted on the vehicle 1 and communicates with the outside, and a mobile terminal 3 that is carried by a user and that performs wireless communication with the communication device 2.

通信機２は、ＤＣＭなどの通信モジュールとされ、携帯端末３は、スマートフォン、タブレット端末、ノートパソコンなどのディスプレイを備えた通信機器である。通信機２は、車載ネットワークを介して種々のＥＣＵに通信可能に接続されるとともに、携帯電話網を利用した移動体通信を行い、インターネットに接続可能とされる。また、通信機２は、無線ＬＡＮ、ブルートゥース（登録商標）、ＺｉｇＢｅｅ（登録商標）などによる近距離無線通信を行い、車内の携帯端末３および車両近傍の携帯端末３と無線通信可能とされる。 The communication device 2 is a communication module such as a DCM, and the mobile terminal 3 is a communication device including a display such as a smartphone, a tablet terminal, and a laptop computer. The communicator 2 is communicatively connected to various ECUs via an in-vehicle network, performs mobile communication using a mobile phone network, and is connectable to the Internet. In addition, the communication device 2 performs short-range wireless communication using a wireless LAN, Bluetooth (registered trademark), ZigBee (registered trademark), or the like, and is capable of wireless communication with the mobile terminal 3 inside the vehicle and the mobile terminal 3 near the vehicle.

通信機２は、移動体通信を行う外部無線通信部１０、近距離無線通信を行う近距離無線通信部１１、通信機２の動作を制御するマイクロコンピュータからなる制御部１２、メモリ１３を備えている。携帯端末３は、移動体通信を行う外部無線通信部１４、近距離無線通信を行う近距離無線通信部１５、タッチパネル付きのディスプレイ１６、携帯端末３の動作を制御するマイクロコンピュータからなる制御部１７、メモリ１８を備えている。通信機２にバッテリから直接電源が供給され、イグニッションスイッチやアクセサリースイッチ（これらを総称して電源スイッチ２０とする）のオン信号により、通信機２は電源オンされ作動する。電源スイッチ２０のオフ信号により、通信機２は、電源オフされ、作動が停止する。通信機２の作動中、携帯端末３は通信機２と近距離無線通信を行える。 The communication device 2 includes an external wireless communication unit 10 that performs mobile communication, a short-range wireless communication unit 11 that performs short-range wireless communication, a control unit 12 including a microcomputer that controls the operation of the communication device 2, and a memory 13. There is. The mobile terminal 3 includes an external wireless communication unit 14 that performs mobile communication, a short-range wireless communication unit 15 that performs short-range wireless communication, a display 16 with a touch panel, and a control unit 17 including a microcomputer that controls the operation of the mobile terminal 3. , A memory 18. Power is directly supplied to the communication device 2 from the battery, and the communication device 2 is powered on and operated by an ON signal of an ignition switch and an accessory switch (collectively referred to as a power switch 20). The off signal of the power switch 20 turns off the power of the communication device 2 and stops its operation. While the communication device 2 is operating, the mobile terminal 3 can perform short-range wireless communication with the communication device 2.

そして、通信機２は、外部無線通信部１０を通じて外部に設置されたセンタ装置２１との間で情報の送受信を行う。また、通信機２は、車載ネットワークに接続された表示装置２２と通信を行う。表示装置２２は、ナビゲーション装置、ディスプレイオーディオ、メーターディスプレイなどのディスプレイを備えた車載機器である。表示装置２２には、通信機２が取得した情報や各種の操作画面、設定画面などが表示される。なお、表示装置２２は、通信機２と一体化されてもよい。 Then, the communication device 2 transmits/receives information to/from the center device 21 installed outside through the external wireless communication unit 10. The communication device 2 also communicates with the display device 22 connected to the in-vehicle network. The display device 22 is an in-vehicle device having a display such as a navigation device, a display audio, and a meter display. The display device 22 displays information acquired by the communication device 2, various operation screens, setting screens, and the like. The display device 22 may be integrated with the communication device 2.

ここで、通信機２と無線通信可能な携帯端末３は、乗車するユーザにより携帯され、通信機２との無線通信が許可された携帯端末３とされる。通信機２を外付けモデムとしてテザリングにより、許可された携帯端末３が通信機２と無線通信可能とされる。まず、通信機２のテザリング機能をオンにする。ここでは、無線ＬＡＮによるテザリングを行う。次に、携帯端末３において、無線ＬＡＮの接続先一覧から通信機２のＩＤを選択し、通信機２のパスワードが入力され、メモリ１８に記憶される。これにより、テザリングが可能となり、携帯端末３は、通信機２との無線通信を許可され、通信機２を通じてインターネットに接続できる。 Here, the mobile terminal 3 that can wirelessly communicate with the communication device 2 is a mobile terminal 3 that is carried by a user who is on board and is permitted to wirelessly communicate with the communication device 2. By using the communication device 2 as an external modem and tethering, the permitted mobile terminal 3 can wirelessly communicate with the communication device 2. First, the tethering function of the communication device 2 is turned on. Here, tethering by wireless LAN is performed. Next, in the mobile terminal 3, the ID of the communication device 2 is selected from the wireless LAN connection destination list, and the password of the communication device 2 is input and stored in the memory 18. As a result, tethering is enabled, the mobile terminal 3 is permitted to perform wireless communication with the communication device 2, and can connect to the Internet through the communication device 2.

通常、テザリングにより携帯端末３はインターネットに常時接続できる。本車両通信システムでは、車両１に複数のユーザが乗っている場合、複数の携帯端末３を１グループとして、期間限定で通信機２と無線通信を行えるようにすることができる。すなわち、グループ設定により、複数の携帯端末３が決められた期間だけ通信機２との無線通信を行うことが許可される。 Usually, the tethering allows the mobile terminal 3 to be constantly connected to the Internet. In the present vehicle communication system, when a plurality of users are on the vehicle 1, the plurality of mobile terminals 3 can be grouped into one group to perform wireless communication with the communication device 2 for a limited time. That is, the group setting permits the plurality of mobile terminals 3 to perform wireless communication with the communication device 2 for a predetermined period.

センタ装置２１は、様々なサービスを提供するために各サービスに応じたアプリケーションを実行する。メインの携帯端末３、例えば車両の使用者の携帯端末３には、サービスを受けるためのアプリケーションが実装されている。まず、この携帯端末３において、アプリケーションを起動して、ログインする。このとき、携帯端末３は、通信機２を介してセンタ装置２１にアクセスする、あるいは携帯電話網を通じてセンタ装置２１に直接アクセスする。 The center device 21 executes an application corresponding to each service in order to provide various services. An application for receiving a service is installed in the main mobile terminal 3, for example, the mobile terminal 3 of a vehicle user. First, in this mobile terminal 3, the application is started and the user logs in. At this time, the mobile terminal 3 accesses the center device 21 via the communication device 2 or directly accesses the center device 21 via the mobile phone network.

携帯端末３のディスプレイ１６に、設定画面の１つとして、図２に示すグループ設定画面が表示される。ここでは、３つのグループを設定することができる。詳細設定として、図３に示すように、表示名（グループ名）、停止条件、接続端末などを設定できる。 The group setting screen shown in FIG. 2 is displayed on the display 16 of the mobile terminal 3 as one of the setting screens. Here, three groups can be set. As a detailed setting, as shown in FIG. 3, a display name (group name), a stop condition, a connection terminal, etc. can be set.

停止条件の設定において、テザリングを行える期間が決められる。なお、停止条件は、設定１〜３に対してデフォルト設定されている。例えば、設定１では、１トリップタイプ、設定２では、目的地連動タイプ、設定３では、１０トリップタイプである。１トリップとは、イグニッションスイッチオンからイグニッションスイッチオフまでの期間とされ、イグニッションスイッチがオフされると、テザリングが停止される。１０トリップでは、１０回のイグニッションスイッチオン／オフがされるまでの期間とされ、１０回目のイグニッションスイッチのオフによりテザリングが停止される。目的地連動では、イグニッションスイッチオンから目的地に到着するまでの期間とされ、目的地に到着して、イグニッションスイッチがオフされると、テザリングが停止される。停止条件の設定によって、デフォルト設定を任意に変更できる。 In setting the stop condition, the period during which tethering can be performed is determined. The stop condition is set as a default for the settings 1 to 3. For example, setting 1 is a 1-trip type, setting 2 is a destination-interlocking type, and setting 3 is a 10-trip type. One trip is a period from turning on the ignition switch to turning off the ignition switch. When the ignition switch is turned off, tethering is stopped. In 10 trips, it is a period until the ignition switch is turned on/off 10 times, and the tethering is stopped by turning off the ignition switch 10 times. In the destination interlocking, it is a period from when the ignition switch is turned on to when the vehicle arrives at the destination. When the vehicle arrives at the destination and the ignition switch is turned off, the tethering is stopped. The default setting can be changed arbitrarily by setting the stop condition.

接続端末の設定において、グループに属する携帯端末３が決められる。通信機２との無線通信可能な携帯端末３のリストが表示され、各携帯端末３に対して、許可／不可が選択される。これにより、複数の携帯端末３の許可をまとめて行える。 The mobile terminals 3 belonging to the group are determined in the setting of the connection terminal. A list of mobile terminals 3 capable of wireless communication with the communication device 2 is displayed, and permission/prohibition is selected for each mobile terminal 3. As a result, it is possible to collectively permit the plurality of mobile terminals 3.

そして、許可が選択された携帯端末３において、ワンタイムパスワードが入力されると、センタ装置２１は、この携帯端末３を認証し、携帯端末３はテザリングによる通信機２との無線通信を許可される。ここで、設定画面の「ワンタイムパスワードを表示する」項目をチェックすると、許可が選択された携帯端末３にワンタイムパスワードが自動的に送信されるか、もしくは手動でも送信できる。各携帯端末３において、ワンタイムパスワードを入力すると、複数の携帯端末３が通信機２との無線通信をまとめて許可される。 Then, when the one-time password is input to the mobile terminal 3 for which permission is selected, the center device 21 authenticates the mobile terminal 3, and the mobile terminal 3 is permitted to perform wireless communication with the communication device 2 by tethering. It Here, when the "Display one-time password" item on the setting screen is checked, the one-time password can be automatically transmitted to the portable terminal 3 for which permission is selected, or can be manually transmitted. When the one-time password is input to each mobile terminal 3, the plurality of mobile terminals 3 are collectively permitted to perform wireless communication with the communication device 2.

このようにして許可された携帯端末３は、決められた期間だけ通信機２を通じてインターネットに接続できる。ところが、本車両通信システムでは、イグニッションスイッチなどの電源スイッチ２０がオフされた後もしばらくの間、通信機２は作動を続ける。この間、携帯端末３は、通信機２との無線通信が可能とされる。 The mobile terminal 3 authorized in this way can connect to the Internet through the communication device 2 for a predetermined period. However, in this vehicle communication system, the communication device 2 continues to operate for a while even after the power switch 20 such as the ignition switch is turned off. During this time, the mobile terminal 3 is capable of wireless communication with the communication device 2.

すなわち、通信機２は、電源スイッチ２０がオフされた後も所定時間だけ携帯端末３と通信可能とされ、所定の操作が行われたときに電源オフする。電源スイッチ２０がオフされても、通信機２にバッテリからの電源が供給され、通信機２は作動し続ける。携帯端末３は、通信機２を通じてインターネットに接続できる。したがって、携帯端末３が通信機２と無線通信をしているとき、電源スイッチ２０がオフされても、携帯端末３は通信機２と無線通信を続けることができ、携帯端末３での作業が中断されるといったことを防いで利便性を高めることができる。 That is, the communication device 2 is allowed to communicate with the mobile terminal 3 for a predetermined time even after the power switch 20 is turned off, and is turned off when a predetermined operation is performed. Even if the power switch 20 is turned off, power is supplied from the battery to the communication device 2 and the communication device 2 continues to operate. The mobile terminal 3 can connect to the Internet through the communication device 2. Therefore, when the mobile terminal 3 is wirelessly communicating with the communication device 2, even if the power switch 20 is turned off, the mobile terminal 3 can continue the wireless communication with the communication device 2, and the work on the mobile terminal 3 can be performed. It is possible to prevent interruption and improve convenience.

図４に示すように、電源スイッチ２０のオフ後、所定時間だけ通信機２は作動し続け、携帯端末３と通信可能とされる。電源スイッチ２０のオフから所定時間経過すると、通信機２は電源オフして、作動を停止する。所定時間が経過する前に、全てのユーザが車両から降りて、所定の操作、すなわち車両キーロックが行われたときに通信機２は電源オフする。このように、電源スイッチ２０のオフ後の通信機２が作動できる期間を制限することにより、バッテリの消費を低減でき、バッテリ上がりを防げる。 As shown in FIG. 4, after the power switch 20 is turned off, the communication device 2 continues to operate for a predetermined time, and communication with the mobile terminal 3 is enabled. When a predetermined time has passed since the power switch 20 was turned off, the communication device 2 is turned off and its operation is stopped. The power of the communication device 2 is turned off when all the users get off the vehicle and perform a predetermined operation, that is, the vehicle key lock before the predetermined time has elapsed. In this way, by limiting the period during which the communication device 2 can operate after the power switch 20 is turned off, battery consumption can be reduced and battery exhaustion can be prevented.

なお、車両キーロック状態で走行し、停車してイグニッションスイッチがオフされたとき、所定時間経過する前に車両キーロックとなっている。この場合、イグニッションスイッチがオフされても、通信機２は電源オフされない。車両キーアンロックが行われて、ユーザが車両１から降りた後、所定時間が経過する前に車両キーロックが行われたとき、通信機２は電源オフされる。 It should be noted that when the vehicle is running in the vehicle key lock state, the vehicle is stopped and the ignition switch is turned off, the vehicle key lock is set before a predetermined time has elapsed. In this case, the communication device 2 is not powered off even if the ignition switch is turned off. When the vehicle key unlock is performed and the vehicle key lock is performed before the predetermined time elapses after the user gets off the vehicle 1, the communication device 2 is powered off.

また、車内に携帯端末３を置き忘れることを防止するために、通信機２は、置き忘れ確認機能を有している。すなわち、通信機２は、電源スイッチ２０がオフされた後も所定時間だけ携帯端末３と通信可能とされ、携帯端末３と通信を行って、車内の携帯端末３の有無を確認する。なお、置き忘れ確認機能は、オンオフ可能とされる。オンされると、この機能が実行される。 In addition, the communication device 2 has a misplacement confirmation function in order to prevent the mobile terminal 3 from being misplaced in the vehicle. That is, the communication device 2 is allowed to communicate with the mobile terminal 3 for a predetermined time even after the power switch 20 is turned off, and communicates with the mobile terminal 3 to check the presence/absence of the mobile terminal 3 in the vehicle. The misplaced confirmation function can be turned on and off. When turned on, this function is executed.

図５に示すように、イグニッションスイッチがオフされて、車両キーロックが行われたとき、通信機２は電源オフしない。車両キーロック後、確認時間だけ経過したとき、例えば３０秒経過したとき、通信機２は、車内の携帯端末からの電波を検知する。車内に携帯端末３がないとき、通信機２は電源オフする。ここでは、イグニッションスイッチのオフから確認時間が経過するまでが所定時間とされる。 As shown in FIG. 5, when the ignition switch is turned off and the vehicle key lock is performed, the power of the communication device 2 is not turned off. The communication device 2 detects the radio wave from the portable terminal in the vehicle when the confirmation time elapses, for example, 30 seconds elapses after the vehicle key lock. When there is no mobile terminal 3 in the vehicle, the communication device 2 is powered off. Here, the predetermined time is from the turning off of the ignition switch to the elapse of the confirmation time.

車内に携帯端末３があると、通信機２はこの携帯端末３からの電波を受信し、置き忘れている携帯端末３を特定できる。通信機２は、無線通信によりメインの携帯端末３に対し、携帯端末３の置き忘れを報知する。メインの携帯端末３を置き忘れている場合、ライト、ホーン、室内ランプを数回動作させることにより、メインの携帯端末３の置き忘れを報知する。なお、他の携帯端末３に対して報知してもよい。通信機２は、報知後、電源オフする。このように、電源スイッチ２０のオフ後も通信機を作動させることにより、携帯端末３の置き忘れを防止でき、より利便性を高めることができる。 When the mobile terminal 3 is in the vehicle, the communication device 2 receives the radio wave from the mobile terminal 3 and can identify the mobile terminal 3 that is left behind. The communication device 2 notifies the main mobile terminal 3 of the misplacement of the mobile terminal 3 by wireless communication. When the main mobile terminal 3 is left behind, the light, the horn, and the interior lamp are operated several times to notify the user that the main mobile terminal 3 is left behind. The other mobile terminal 3 may be notified. The communication device 2 is powered off after the notification. As described above, by operating the communication device even after the power switch 20 is turned off, the portable terminal 3 can be prevented from being left behind and the convenience can be improved.

なお、本発明は、上記実施形態に限定されるものではなく、本発明の範囲内で上記実施形態に多くの修正および変更を加え得ることは勿論である。ブルートゥース（登録商標）によるテザリングを行ってもよい。通信機２と個々の携帯端末３とがペアリングを行うことにより、通信機２と各携帯端末３とが無線通信可能となる。また、通信機２を電源オフするときの所定の操作として、携帯端末３における通信終了の操作としてもよい。この操作が行われると、携帯端末３から通信機２に終了信号が送信され、終了信号を受信した通信機２は電源オフする。 The present invention is not limited to the above embodiment, and it goes without saying that many modifications and changes can be made to the above embodiment within the scope of the present invention. You may perform tethering by Bluetooth (registered trademark). By performing pairing between the communication device 2 and each mobile terminal 3, the communication device 2 and each mobile terminal 3 can wirelessly communicate with each other. Further, the predetermined operation for turning off the power of the communication device 2 may be an operation for ending communication in the mobile terminal 3. When this operation is performed, an end signal is transmitted from the mobile terminal 3 to the communication device 2, and the communication device 2 that receives the end signal turns off the power.
