Description

車載装置、車両、切断検知方法、及びプログラムIn-vehicle device, vehicle, disconnection detection method, and program
　本発明は、車載装置、車両、切断検知方法、及びプログラムに関する。 The present invention relates to an in-vehicle device, a vehicle, a disconnection detection method, and a program.
　車両に搭載された車載装置により、車両の走行位置、速度、加速度等の走行に係る情報を含むプローブ情報を取得する技術が知られている。 技術 There is known a technique for acquiring probe information including information related to traveling such as a traveling position, a speed, and an acceleration of a vehicle by using an in-vehicle device mounted on the vehicle.
　車載装置が取得したプローブ情報は、センターサーバ等で収集されて様々な目的のために使用される。
　例えば、特許文献１には、センターサーバが収集したプローブ情報に基づいて、車両が課金エリア（課金対象となる領域又は道路）を走行したか否かを判断して課金を行う課金システムが記載されている。
　また、他の例として、センターサーバが収集したプローブ情報に基づいて、車両の急発進、急ブレーキ、速度超過等を検出し、車両の運転者が安全運転又はエコ運転（環境に配慮した運転）を行ったか否かを評価する運転評価システムが考えられている。更に、センターサーバがタクシーに搭載された車載装置から収集したプローブ情報に基づいて、タクシーの走行経路、走行距離、走行時間、料金等を集計して業務管理を行うシステムが考えられている。 The probe information acquired by the in-vehicle device is collected by a center server or the like and used for various purposes.

　車載装置は、車両の起動信号（例えばイグニッション（ＩＧＣＴ）スイッチのＯＮを示す信号）の入力を受け付けると起動され、プローブ情報を取得してセンターサーバへ送信する処理を継続して実行する。また、車両の停止信号（例えばＩＧＣＴスイッチのＯＦＦを示す信号）の入力を受け付けるとプローブ情報の取得及び送信処理を含む各種処理を終了し、非起動状態となる。 (4) The vehicle-mounted device is activated upon receiving an input of a vehicle activation signal (for example, a signal indicating that an ignition (IGCT) switch is turned on), and continuously executes a process of acquiring probe information and transmitting the probe information to the center server. Further, when an input of a vehicle stop signal (for example, a signal indicating that the IGCT switch is turned off) is received, various processes including a process of acquiring and transmitting probe information are terminated, and the vehicle is brought into a non-activated state.
　しかしながら、車載装置に車両の起動信号を入力するための入力線が故障により断線した場合、又は不正行為により接続されていない場合、車両が起動信号を出力しても車載装置は起動されなくなる。そうすると、例えば車両が課金エリアを走行した場合あっても、センターサーバは当該車両の車載装置からプローブ情報を収集できないので、当該車両に正しく課金できない可能性がある。また、同様に、車両が走行中に車載装置が起動していない期間があると、センターサーバは、プローブ情報に基づく運転評価、タクシーの業務管理等の様々な処理を正しく行うことができない可能性がある。 However, if the input line for inputting the activation signal of the vehicle to the in-vehicle device is disconnected due to a failure or is not connected due to fraud, the in-vehicle device will not be activated even if the vehicle outputs the activation signal. Then, for example, even if the vehicle runs through the charging area, the center server cannot collect the probe information from the in-vehicle device of the vehicle, so that the vehicle may not be correctly charged. Similarly, if there is a period in which the vehicle-mounted device is not activated while the vehicle is running, the center server may not be able to correctly perform various processes such as driving evaluation based on the probe information and taxi business management. There is.

As shown in FIG. 1, the disconnection detection system 1 includes a vehicle 10, an in-vehicle device 20 mounted on the vehicle 10, and a center server 30.
In the example of FIG. 1, one vehicle 10 and one center server 30 are shown, but the invention is not limited to this. The disconnection detection system 1 may be configured to include a plurality of vehicles 10 and a plurality of center servers 30.
　車両１０は、イグニッション（ＩＧＣＴ）スイッチ１１と、バッテリ１２とを有している。
　ＩＣＧＴスイッチ１１は、運転者によりＯＮ操作が行われるとイグニッション信号を「ＯＮ」にする。また、ＩＧＣＴスイッチ１１は、運転者によりＯＦＦ操作が行われると、イグニッション信号を「ＯＦＦ」にする。なお、イグニッション信号は、入力線Ｌ１を介して車載装置２０に入力される。
　バッテリ１２は、電源線Ｌ２を介して車載装置２０に接続され、車載装置２０が動作するための電力を供給する。 The vehicle 10 has an ignition (IGCT) switch 11 and a battery 12.
The ICGT switch 11 turns the ignition signal “ON” when the driver performs an ON operation. In addition, when the driver performs an OFF operation, the IGCT switch 11 turns the ignition signal “OFF”. Note that the ignition signal is input to the in-vehicle device 20 via the input line L1.
The battery 12 is connected to the in-vehicle device 20 via the power line L2, and supplies power for the in-vehicle device 20 to operate.
　車載装置２０は、ＩＣＧＴスイッチ１１から入力線Ｌ１を介して入力されたイグニッション信号に基づいて、起動又は停止（スリープ）を行う。
　本実施形態では、車載装置２０は、イグニッション信号が「ＯＮ」のとき、起動信号が入力されたと判断して起動する。一方、車載装置２０は、イグニッション信号が「ＯＦＦ」のとき、起動信号が入力されていないと判断して停止（スリープ）する。

（処理フロー）
　図３は、本発明の第１の実施形態に係る切断検知システムの処理の一例を示す第１のフローチャートである。
　図４は、本発明の第１の実施形態に係る切断検知システムの処理の一例を示す第２のフローチャートである。
　以下、図３～図４を参照して、車載装置２０の切断検知部２１が入力線Ｌ１の切断の有無を検知する処理の一例について説明する。
　まず、判断部２１２は、入力線Ｌ１の切断の有無を監視する前に、入力線Ｌ１の切断検知フラグを初期化（ＦＬＡＧ＝０）する（ステップＳ１０）。例えば、判断部２１２は、車載装置２０の電源ＯＦＦ時に切断検知フラグを初期化する。 (Processing flow)
FIG. 3 is a first flowchart illustrating an example of processing of the disconnection detection system according to the first embodiment of the present invention.
FIG. 4 is a second flowchart illustrating an example of processing of the disconnection detection system according to the first embodiment of the present invention.
Hereinafter, an example of a process in which the disconnection detection unit 21 of the in-vehicle device 20 detects whether or not the input line L1 has been disconnected will be described with reference to FIGS.
First, before monitoring whether the input line L1 is disconnected, the determination unit 212 initializes a disconnection detection flag of the input line L1 (FLAG = 0) (step S10). For example, the determination unit 212 initializes a disconnection detection flag when the power of the vehicle-mounted device 20 is turned off.
　次に、判断部２１２は、入力線Ｌ１の切断の有無を監視する監視ループを開始する（ステップＳ１１）。この監視ループにおいて、起動判定部２１０は、ＩＧＣＴスイッチ１１からの起動信号の入力の有無を常時監視する。そして、判断部２１２は、起動判定部２１０により起動信号が入力されていないと判断され、且つ、切断検知フラグが初期状態（ＦＬＡＧ＝０）である間、以下のステップＳ１２～Ｓ１４を繰り返し実行する。 Next, the determination unit 212 starts a monitoring loop for monitoring whether or not the input line L1 has been disconnected (step S11). In this monitoring loop, the activation determination unit 210 constantly monitors the presence or absence of the input of the activation signal from the IGCT switch 11. Then, the determination unit 212 repeatedly executes the following steps S12 to S14 while the activation determination unit 210 determines that the activation signal has not been input and the disconnection detection flag is in the initial state (FLAG = 0). .
　動作判定部２１１は、検知センサから所定の間隔（例えば１０分）おきに検知信号を取得する（ステップＳ１２）。
　本実施形態では、動作判定部２１１は、衛星信号受信部２３から車両１０の位置情報を検知信号として取得する。 The operation determining unit 211 acquires a detection signal from the detection sensor at predetermined intervals (for example, every 10 minutes) (Step S12).
In the present embodiment, the operation determining unit 211 acquires the position information of the vehicle 10 from the satellite signal receiving unit 23 as a detection signal.
　次に、動作判定部２１１は、時系列に連続する位置情報に基づいて、車両１０が動いているか否かを判定する（ステップＳ１３）。
　具体的には、動作判定部２１１は、ステップＳ１２において取得した最新の位置情報と、前回取得した位置情報とを比較する。そして、動作判定部２１１は、車両１０の位置が所定距離（例えば１０ｍ）以上変化した場合、車両１０が動いていると判定する（ステップＳ１３：ＹＥＳ）。一方、動作判定部２１１は、車両１０の位置が所定距離以上変化していない場合、車両１０が動いていないと判定する（ステップＳ１３：ＮＯ）。 Next, the operation determining unit 211 determines whether or not the vehicle 10 is moving, based on the time-series continuous position information (Step S13).
Specifically, the operation determining unit 211 compares the latest position information acquired in step S12 with the previously acquired position information. Then, when the position of the vehicle 10 has changed by a predetermined distance (for example, 10 m) or more, the operation determination unit 211 determines that the vehicle 10 is moving (Step S13: YES). On the other hand, when the position of the vehicle 10 has not changed by the predetermined distance or more, the operation determination unit 211 determines that the vehicle 10 is not moving (step S13: NO).
　次に、判断部２１２は、動作判定部２１１により車両１０が動いていると判定された場合（ステップＳ１３：ＹＥＳ）、入力線Ｌ１が切断されていると判断して、切断検知フラグをＯＮ（ＦＬＡＧ＝１）にする（ステップＳ１４）。 Next, when the operation determination unit 211 determines that the vehicle 10 is moving (step S13: YES), the determination unit 212 determines that the input line L1 has been disconnected, and turns on the disconnection detection flag (step S13). FLAG = 1) (step S14).
　また、判断部２１２は、動作判定部２１１により車両１０が動いていないと判定された場合（ステップＳ１３：ＮＯ）、処理を行わずに待機する。 判断 Further, when the operation determining unit 211 determines that the vehicle 10 is not moving (step S13: NO), the determining unit 212 waits without performing any processing.
　次に、判断部２１２は監視ループの終了条件チェックを行う（ステップＳ１５）。判断部２１２は、起動信号が入力された場合、又は、切断検知フラグがＯＮ（ＦＬＡＧ＝１）になった場合、監視ループを抜け、図４の処理に進む。一方、判断部２１２は、起動信号が入力されておらず、且つ、切断検知フラグがＯＦＦ（ＦＬＡＧ＝０）のままである場合、ステップＳ１２に戻り、上述の各ステップを繰り返し実行する。 Next, the judgment unit 212 checks the termination condition of the monitoring loop (step S15). When the activation signal is input or the disconnection detection flag is turned ON (FLAG = 1), the determination section 212 exits the monitoring loop and proceeds to the processing in FIG. On the other hand, when the activation signal has not been input and the disconnection detection flag remains OFF (FLAG = 0), the determination unit 212 returns to step S12 and repeatedly executes the above steps.
　次に、判断部２１２は、監視ループを抜けた後、入力線Ｌ１の切断が検知された（ＦＬＡＧ＝１）場合（ステップＳ１６：ＹＥＳ）、当該入力線Ｌ１の切断を示す切断ログを記憶部２５に記憶する（ステップＳ１７）。 Next, when the disconnection of the input line L1 is detected (FLAG = 1) after exiting the monitoring loop (step S16: YES), the determination unit 212 stores a disconnection log indicating the disconnection of the input line L1. 25 (step S17).
　また、通知処理部２１３は、入力線Ｌ１の切断が検知された（ＦＬＡＧ＝１）場合（ステップＳ１６：ＹＥＳ）、当該入力線Ｌ１の切断を示す情報（切断ログ）と、車両１０を特定可能な識別情報とを関連付けた「切断検知情報Ｄ１（図５）」をセンターサーバ３０に通知する（ステップＳ１８）。
　図５は、本発明の第１の実施形態に係る切断検知情報の一例を示す図である。
　図５に示すように、切断検知情報Ｄ１は、「識別情報」と、入力線Ｌ１の切断を検知した「検知日時」と、「検知内容」とを含む。識別情報は、車両１０を特定可能であればどのような情報でもよく、例えば、車両１０のナンバープレート情報（分類番号、車両番号等）、車両１０に搭載された車載装置２０の車載装置ＩＤ等である。また、「検知内容」は、「入力線Ｌ１の切断」を示す情報であり、テキスト情報であってもよいし、予めセンターサーバ３０との間で規定されたエラーコードであってもよい。 When disconnection of the input line L1 is detected (FLAG = 1) (step S16: YES), the notification processing unit 213 can specify information indicating the disconnection of the input line L1 (disconnection log) and the vehicle 10. The disconnection detection information D1 (FIG. 5) associated with the relevant identification information is notified to the center server 30 (step S18).
FIG. 5 is a diagram illustrating an example of the disconnection detection information according to the first embodiment of the present invention.
As shown in FIG. 5, the disconnection detection information D1 includes “identification information”, “detection date and time” at which the disconnection of the input line L1 is detected, and “detection content”. The identification information may be any information as long as the vehicle 10 can be identified. For example, the license plate information (classification number, vehicle number, etc.) of the vehicle 10, the vehicle-mounted device ID of the vehicle-mounted device 20 mounted on the vehicle 10, and the like. It is. The “detection content” is information indicating “cutting of the input line L1”, and may be text information or an error code defined in advance with the center server 30.
　また、図４の説明に戻って、入力線Ｌ１の切断が検知されていない（ＦＬＡＧ＝０）場合（ステップＳ１６：ＮＯ）、ＩＧＣＴスイッチ１１から起動信号が入力されているため、電源制御部２２により車載装置２０の電源がＯＮされる（ステップＳ１９）。 Returning to the description of FIG. 4, when disconnection of the input line L1 is not detected (FLAG = 0) (step S16: NO), since the start signal is input from the IGCT switch 11, the power supply control unit 22 The power of the in-vehicle device 20 is turned on (step S19).
　車載装置２０は、電源ＯＦＦされる度に図３～図４に示される処理を繰り返し実行、入力線Ｌ１の切断の有無を監視する。
　なお、図４の例では、通知処理部２１３は、入力線Ｌ１の切断を検知する度にセンターサーバ３０に切断検知情報Ｄ１を通知するが、これに限られることはない。他の実施形態では、通知処理部２１３は、所定の時間（例えば１日）が経過したタイミング、又は、車載装置２０が電源ＯＮされたタイミングで、記憶部２５に切断ログが記憶されている場合、センターサーバ３０に切断検知情報Ｄ１を通知するようにしてもよい。このとき、記憶部２５に複数の切断ログが記憶されている場合、通知処理部２１３は、複数の切断ログを含む切断検知情報Ｄ１を作成してセンターサーバ３０に通知してもよい。 The in-vehicle device 20 repeatedly executes the processing shown in FIGS. 3 and 4 every time the power is turned off, and monitors whether or not the input line L1 is disconnected.
In the example of FIG. 4, the notification processing unit 213 notifies the center server 30 of the disconnection detection information D1 each time the disconnection of the input line L1 is detected, but is not limited thereto. In another embodiment, the notification processing unit 213 stores the disconnection log in the storage unit 25 at a timing when a predetermined time (for example, one day) has elapsed or when the power of the in-vehicle device 20 is turned on. Alternatively, the disconnection detection information D1 may be notified to the center server 30. At this time, when a plurality of disconnection logs are stored in the storage unit 25, the notification processing unit 213 may create disconnection detection information D1 including the plurality of disconnection logs and notify the center server 30.
　センターサーバ３０には、車両１０それぞれから通知された切断検知情報Ｄ１が記憶される。
　例えば課金システムの管理者は、センターサーバ３０に記憶された切断検知情報Ｄ１を参照することにより、故障又は不正行為により入力線Ｌ１が切断されている車両１０を特定し、当該車両１０のユーザに警告、ペナルティを与えるようにしてもよい。
　また、センターサーバ３０が定期的（例えば１ヶ月毎）に切断検知情報Ｄ１を確認し、入力線Ｌ１が切断されている車両１０に対して警告、ペナルティを与える処理を自動的に実行するようにしてもよい。このようにすることで、センターサーバ３０は、ユーザの不正行為等を取り締まることができる。 The center server 30 stores disconnection detection information D1 notified from each of the vehicles 10.
For example, the administrator of the billing system refers to the disconnection detection information D1 stored in the center server 30 to identify the vehicle 10 whose input line L1 has been disconnected due to a malfunction or an improper action, and A warning and a penalty may be given.
Further, the center server 30 periodically (for example, every month) checks the disconnection detection information D1 and automatically executes a process of giving a warning and a penalty to the vehicle 10 whose input line L1 has been disconnected. You may. By doing in this way, the center server 30 can control user's misconduct and the like.
（作用効果）
　以上のように、本実施形態に係る車載装置２０は、車両１０の起動信号が入力線Ｌ１を介して入力されているか否かを判定する起動判定部２１０と、車両１０の動きを検知可能な衛星信号受信部２３（検知センサ）から受け付ける位置情報（検知信号）に基づいて、車両１０が動いているか否かを判定する動作判定部２１１と、起動信号が入力されていないと判定され、且つ、車両１０が動いていると判定された場合、入力線Ｌ１が切断されていると判断する判断部２１２と、を備える。
　このようにすることで、車載装置２０は、入力線Ｌ１に断線、接触不良等の故障が生じていること、又は、不正行為により入力線Ｌ１が車載装置２０に接続されていないことを検知することができる。 (Effects)
As described above, the in-vehicle device 20 according to the present embodiment can detect the movement of the vehicle 10 and the activation determination unit 210 that determines whether the activation signal of the vehicle 10 is input via the input line L1. Based on the position information (detection signal) received from the satellite signal reception unit 23 (detection sensor), an operation determination unit 211 that determines whether the vehicle 10 is moving, a determination is made that an activation signal has not been input, and A determination unit 212 that determines that the input line L1 has been disconnected when it is determined that the vehicle 10 is moving.
By doing so, the in-vehicle device 20 detects that a failure such as disconnection or poor contact has occurred in the input line L1 or that the input line L1 is not connected to the in-vehicle device 20 due to fraud. be able to.
　また、判断部２１２は、入力線Ｌ１が切断されていると判断した場合、当該入力線Ｌ１の切断を示す情報である切断ログを記憶部２５に記憶する。
　このように、入力線Ｌ１が切断されたことが記憶されることにより、ユーザ（車両の運転者等）が故意に入力線Ｌ１を切断する等の不正行為を行うことを抑制することができる。 When determining that the input line L1 is disconnected, the determination unit 212 stores a disconnection log, which is information indicating the disconnection of the input line L1, in the storage unit 25.
By storing the fact that the input line L1 has been disconnected in this way, it is possible to prevent a user (a driver of a vehicle or the like) from intentionally performing an illegal act such as disconnecting the input line L1.
　また、車載装置２０は、入力線Ｌ１が切断されていると判断された場合、当該入力線Ｌ１の切断を示す情報である切断ログと、前記車両１０を特定可能な識別情報とを関連付けた切断検知情報Ｄ１を通知する通知処理部２１３を更に備える。

　また、車載装置２０の通知処理部２１３は、記憶部２５に記憶された切断ログを参照し、所定のタイミングで切断検知情報Ｄ１を通知するようにしてもよい。これにより、課金システムの管理者等は、過去に当該車載装置２０において入力線Ｌ１が切断されたか否かを認識することができる。 When it is determined that the input line L1 is disconnected, the in-vehicle device 20 disconnects the disconnection log, which is information indicating the disconnection of the input line L1, and the identification information that can identify the vehicle 10. It further includes a notification processing unit 213 that notifies the detection information D1.
By doing so, the in-vehicle device 20 can notify the user or the like of the disconnection of the input line L1 due to the failure by notifying that the input line L1 has been disconnected, and also allows the user to intentionally input the input line L1. It is possible to suppress performing an illegal act such as disconnecting L1.
Further, the notification processing unit 213 of the in-vehicle device 20 may refer to the disconnection log stored in the storage unit 25 and notify the disconnection detection information D1 at a predetermined timing. Thereby, the administrator of the charging system or the like can recognize whether or not the input line L1 has been disconnected in the in-vehicle device 20 in the past.
　また、車載装置２０は、検知センサとして、衛星から受信した信号に基づいて車両１０の位置を特定し、位置情報（検知信号）として出力する衛星信号受信部２３を更に備え、動作判定部２１１は、時系列に連続する位置情報を比較して、当該車両１０が動いているか否かを判定する。
　このようにすることで、動作判定部２１１は、衛星から受信した信号に基づいて、車両１０が動いているか否かを判定することができる。
　また、動作判定部２１１は、車両１０の位置が所定距離以上変化した場合、当該車両１０が動いていると判定してもよい。これにより、動作判定部２１１は、センサ誤差により車両１０が動いていると誤判定してしまうことを抑制できる。 The in-vehicle device 20 further includes, as a detection sensor, a satellite signal receiving unit 23 that specifies the position of the vehicle 10 based on a signal received from a satellite and outputs the position as position information (detection signal). Then, it is determined whether or not the vehicle 10 is moving by comparing the time-series continuous position information.
In this way, the operation determining unit 211 can determine whether the vehicle 10 is moving based on the signal received from the satellite.
When the position of the vehicle 10 has changed by a predetermined distance or more, the operation determination unit 211 may determine that the vehicle 10 is moving. Thereby, the operation determination unit 211 can suppress erroneous determination that the vehicle 10 is moving due to a sensor error.
＜第２の実施形態＞
　次に、本発明の第２の実施形態に係る切断検知システム１について図６を参照しながら説明する。

Next, a cutting detection system 1 according to a second embodiment of the present invention will be described with reference to FIG.
The same components as those in the first embodiment are denoted by the same reference numerals, and the detailed description is omitted.
　図６は、本発明の第２の実施形態に係る切断検知システムの機能構成を示す図である。
　図６に示すように、本実施形態に係る車載装置２０は、ジャイロセンサ２７を更に有している。 FIG. 6 is a diagram illustrating a functional configuration of a disconnection detection system according to the second embodiment of the present invention.
As shown in FIG. 6, the in-vehicle device 20 according to the present embodiment further includes a gyro sensor 27.

In the present embodiment, the gyro sensor 27 functions as a detection sensor capable of detecting the movement of the vehicle 10 (change in inclination such as the traveling direction). Then, the gyro sensor 27 outputs the measured angular velocity to the cutting detection unit 21 as a detection signal.

＜第５の実施形態＞
　次に、本発明の第５の実施形態に係る切断検知システム１について図９を参照しながら説明する。
　上述の各実施形態と共通の構成要素には同一の符号を付して詳細説明を省略する。 <Fifth embodiment>
Next, a cutting detection system 1 according to a fifth embodiment of the present invention will be described with reference to FIG.
The same reference numerals are given to the same components as those in the above-described embodiments, and the detailed description will be omitted.
　図９は、本発明の第５の実施形態に係る切断検知システムの機能構成を示す図である。
　図９に示すように、本実施形態に係る車両１０は、検知センサとして車両センサ１３を有している。車両センサ１３は、例えば、車両１０の走行距離、イグニッション状態、速度、加速度、角速度、ステアリング角度を計測して検知信号として出力する速度センサ、加速度センサ、ジャイロセンサ、舵角センサのうち少なくとも一つである。なお、走行距離は、車両１０の製造完了後からの累積の総走行距離を意味する。イグニッション状態は、車両１０から出力される車両状態を示す信号に含まれる、エンジンＯＮ（イグニッションＯＮ）、アクセサリＯＮ、エンジンＯＦＦ等の状態を意味する。
　また、本実施形態に係る車載装置２０は、車両センサ１３から出力された検知信号を取得する検知信号取得部２９を有している。なお、検知信号取得部２９は、車両センサ１３から車両１０の走行距離、イグニッション状態、速度、加速度、角速度、及びステアリング角度のうち一つのみを取得してもよいし、複数を取得してもよい。 FIG. 9 is a diagram illustrating a functional configuration of a disconnection detection system according to the fifth embodiment of the present invention.
As shown in FIG. 9, the vehicle 10 according to the present embodiment has a vehicle sensor 13 as a detection sensor. The vehicle sensor 13 is, for example, at least one of a speed sensor, an acceleration sensor, a gyro sensor, and a steering angle sensor that measures a travel distance, an ignition state, a speed, an acceleration, an angular velocity, and a steering angle of the vehicle 10 and outputs the detection signal. It is. The mileage means the total mileage accumulated since the completion of the manufacture of the vehicle 10. The ignition state means a state such as an engine ON (ignition ON), an accessory ON, an engine OFF, and the like, which are included in a signal indicating a vehicle state output from the vehicle 10.
The in-vehicle device 20 according to the present embodiment includes a detection signal acquisition unit 29 that acquires a detection signal output from the vehicle sensor 13. Note that the detection signal acquisition unit 29 may acquire only one of the travel distance, the ignition state, the speed, the acceleration, the angular velocity, and the steering angle of the vehicle 10 from the vehicle sensor 13 or may acquire a plurality of them. Good.
　本実施形態に係る切断検知部２１の動作判定部２１１は、入力線Ｌ１の監視ループ（図３）において、検知センサである車両センサ１３から、検知信号取得部２９を介して、検知信号を取得する（図３のステップＳ１２）。
　そして、動作判定部２１１は、取得した最新の検知信号と、前回取得した検知信号とを比較して、検知信号の変化量が所定の閾値以上である場合、車両１０が動いていると判定する（ステップＳ１３：ＹＥＳ）。一方、動作判定部２１１は、検知信号の変化量が所定の閾値以上でない場合、車両１０が動いていないと判定する（ステップＳ１３：ＮＯ）。
　なお、閾値は車両センサ１３から取得する検知信号の種別に応じて予め定められる。例えば、動作判定部２１１は、車両１０の速度を検知信号として取得する場合、所定の速度（１０ｋｍ／ｈ）以上である状態が一定時間（例えば１分間）以上継続した場合、当該車両１０が動いていると判定する。即ち、閾値には、車両１０が動いていると判定するための変化量の閾値と、その継続時間の閾値との両方が含まれていてもよい。これにより、動作判定部２１１は、センサ誤差、信号ノイズ等に起因する、短期間の検知信号の変化を無視することができる。
　また、動作判定部２１１は、検知信号取得部２９が取得した検知信号のうち、何れか一つに基づいて車両１０が動いているか否か判定してもよいし、二つ以上の検知信号を組み合わせて判定してもよい。 The operation determination unit 211 of the disconnection detection unit 21 according to the present embodiment acquires a detection signal from the vehicle sensor 13 as a detection sensor via the detection signal acquisition unit 29 in the monitoring loop of the input line L1 (FIG. 3). (Step S12 in FIG. 3).
Then, the operation determination unit 211 compares the acquired latest detection signal with the previously acquired detection signal, and determines that the vehicle 10 is moving when the amount of change in the detection signal is equal to or greater than a predetermined threshold. (Step S13: YES). On the other hand, when the amount of change in the detection signal is not greater than or equal to the predetermined threshold, the operation determination unit 211 determines that the vehicle 10 is not moving (step S13: NO).
The threshold is determined in advance according to the type of the detection signal acquired from the vehicle sensor 13. For example, when acquiring the speed of the vehicle 10 as a detection signal, the operation determination unit 211 moves the vehicle 10 when a state in which the speed is equal to or higher than a predetermined speed (10 km / h) continues for a predetermined time (for example, 1 minute). It is determined that there is. That is, the threshold value may include both the threshold value of the amount of change for determining that the vehicle 10 is moving and the threshold value of the duration thereof. Accordingly, the operation determination unit 211 can ignore a short-term change in the detection signal due to a sensor error, signal noise, or the like.
In addition, the operation determination unit 211 may determine whether the vehicle 10 is moving based on any one of the detection signals acquired by the detection signal acquisition unit 29, and may determine two or more detection signals. The determination may be made in combination.
　以上のように、本実施形態に係る車載装置２０は、車両１０に設けられた検知センサ１３から出力され、当該車両１０の速度、加速度、角速度、及びステアリング角度のうち少なくとも一つを含む検知信号を受信する検知信号取得部２９を更に備え、動作判定部２１１は、時系列に連続する検知信号を比較して、当該車両１０が動いているか否かを判定する。
　このようにすることで、動作判定部２１１は、車両１０に予め設けられている車両センサ１３から出力された検知信号に基づいて、車両１０が動いているか否かを判定することができる。
　また、動作判定部２１１は、検知信号の変化量が所定の閾値以上である場合、又は、検知信号の変化量が所定の閾値以上である状態が一定時間以上継続した場合、車両１０が動いていると判定してもよい。これにより、動作判定部２１１は、センサ誤差により車両１０が動いていると誤判定してしまうことを抑制できる。 As described above, the vehicle-mounted device 20 according to the present embodiment outputs the detection signal output from the detection sensor 13 provided in the vehicle 10 and including at least one of the speed, acceleration, angular velocity, and steering angle of the vehicle 10. Is further provided, and the operation determining unit 211 compares the detection signals that are continuous in time series to determine whether the vehicle 10 is moving.
By doing so, the operation determining unit 211 can determine whether or not the vehicle 10 is moving, based on the detection signal output from the vehicle sensor 13 provided in the vehicle 10 in advance.
In addition, when the amount of change in the detection signal is equal to or more than the predetermined threshold, or when the state in which the amount of change in the detection signal is equal to or more than the predetermined threshold continues for a certain period of time, the operation of the vehicle 10 is determined. May be determined. Thereby, the operation determination unit 211 can suppress erroneous determination that the vehicle 10 is moving due to a sensor error.

　また、更に他の実施形態では、車載装置２０は、入力線Ｌ１の切断を検知した場合、車載装置２０又は車両１０の一部機能を制限する（例えば、入力線Ｌ１の接続を確認するまでイグニッションＯＮ操作を制限する等）指令を出力するようにしてもよい。これにより、車載装置２０は、ユーザに対し、車両１０を正常に動作させるために、入力線Ｌ１が正しく接続することを促すことができる。 As described above, the embodiments of the present invention have been described in detail. However, the present invention is not limited to these, and may be slightly changed in design without departing from the technical idea of the present invention.
For example, in each of the above embodiments, when the disconnection of the input line L1 is detected, the mode in which the in-vehicle device 20 stores the disconnection log in the storage unit 25 and notifies the center server 30 of the disconnection detection information D1 has been described. It is not limited to this. In another embodiment, the power control unit 22 of the vehicle-mounted device 20 turns on the power of the vehicle-mounted device 20 when detecting that the vehicle 10 is moving despite the fact that the activation signal is not input. Is also good. By doing so, even when the input line L1 is disconnected, when the vehicle 10 is moving, the in-vehicle device 20 can be activated, and the acquisition and transmission of probe information can be performed correctly.
Further, in still another embodiment, when detecting the disconnection of the input line L1, the in-vehicle device 20 limits some functions of the in-vehicle device 20 or the vehicle 10 (for example, until the connection of the input line L1 is confirmed, the ignition is performed). A command may be output). Thereby, the in-vehicle device 20 can prompt the user to connect the input line L1 correctly in order to operate the vehicle 10 normally.
　また、上述の各実施形態において、通知処理部２１３は、切断検知情報Ｄ１をセンターサーバ３０に通知する態様について説明したが、これに限られることはない。通知処理部２１３は、ユーザ（車両１０の運転者等）に対し、車載装置２０の表示部及びスピーカ（不図示）を用いて切断検知情報Ｄ１を通知（テキストメッセージ、音声による通知等）してもよい。
　これにより、通知処理部２１３は、ユーザに対し入力線Ｌ１を修理する、又は、正しく接続することを促すことができる。 Further, in each of the above-described embodiments, the mode in which the notification processing unit 213 notifies the center server 30 of the disconnection detection information D1 has been described, but the present invention is not limited to this. The notification processing unit 213 notifies the user (the driver of the vehicle 10 or the like) of the disconnection detection information D1 using a display unit and a speaker (not shown) of the vehicle-mounted device 20 (a text message, a voice notification, or the like). Is also good.
Thereby, the notification processing unit 213 can prompt the user to repair the input line L1 or to connect the input line L1 correctly.
　また、上述の各実施形態において、車載装置２０が各機能部（切断検知部２１、電源制御部２２、検知センサ（衛星信号受信部２３、ジャイロセンサ２７、加速度センサ２８、広帯域通信部２４）、記憶部２５、ＣＰＵ２６）を有する態様について説明したが、これに限られることはない。他の実施形態では、車両１０がこれらの機能部を有していてもよい。 In each of the above-described embodiments, the in-vehicle device 20 includes the functional units (the disconnection detection unit 21, the power control unit 22, the detection sensors (the satellite signal reception unit 23, the gyro sensor 27, the acceleration sensor 28, the broadband communication unit 24) Although the mode having the storage unit 25 and the CPU 26) has been described, the present invention is not limited to this. In another embodiment, the vehicle 10 may have these functional units.
　また、上述の各実施形態において、センターサーバ３０がプローブ情報に基づいて課金処理を実行する態様について説明したが、これに限られることはない。他の実施形態では、センターサーバ３０は、プローブ情報に含まれる車両１０の速度、加速度、角速度等に基づいて、車両１０の急発進、急ブレーキ、急ハンドル、速度超過等を検出し、車両の運転者が安全運転又はエコ運転を行ったか否かを評価する運転評価処理を実行してもよい。
　更に、他の実施形態では、センターサーバ３０は、タクシーに搭載された車載装置２０から収集したプローブ情報に基づいて、タクシーの走行経路、走行距離、走行時間、料金等を集計して業務管理処理を実行してもよい。 Further, in each of the above-described embodiments, the mode in which the center server 30 executes the billing process based on the probe information has been described, but the present invention is not limited to this.

　また、上述の第５の実施形態において、動作判定部２１１は、車両１０の検知信号の変化量が閾値以上である状態が、一定時間（例えば１分間）以上継続した場合、当該車両１０が動いていると判定する態様について説明した。当該態様は、第１から第４の実施形態に係る動作判定部２１１に適用されてもよい。これにより、動作判定部２１１は、センサ誤差、信号ノイズ等に起因する、短期間の検知信号の変化を無視することができる。これにより、動作判定部２１１は、車両１０が動いているか否かを判定する精度が低下してしまうことを抑制することができる。 In the above-described fifth embodiment, when the state in which the amount of change in the detection signal of the vehicle 10 is equal to or greater than the threshold continues for a certain time (for example, one minute), the operation determination unit 211 moves the vehicle 10. The aspect in which the determination is made has been described. This aspect may be applied to the operation determining unit 211 according to the first to fourth embodiments. Accordingly, the operation determination unit 211 can ignore a short-term change in the detection signal due to a sensor error, signal noise, or the like. Thereby, the operation determination unit 211 can suppress a decrease in the accuracy of determining whether the vehicle 10 is moving.
