The management base station M is a company that owns the vehicle T or a company that maintains the vehicle T, for example. When the staff of the management base station M receives a notification that an abnormality has occurred in the vehicle T from the abnormality notification device 1, it notifies the driver of the vehicle T that an abnormality has occurred, or maintains the vehicle T. By doing so, serious accidents can be prevented.
　異常通知装置１は、検出した異常状態の内容に基づいて、車両Ｔを管理する管理基地局Ｍに異常状態を通知するか否かを判定する。異常通知装置１は、管理基地局Ｍに通知すると判定した異常状態の情報を管理基地局Ｍに送信する。また、異常通知装置１は、検出した異常状態の内容に基づいて、車両Ｔを運転する運転者に異常状態を通知するか否かを判定する。異常通知装置１は、運転者に通知すると判定した異常状態の情報を運転者に送信する。 The abnormality notification device 1 determines whether or not to notify the management base station M managing the vehicle T of the abnormal state based on the content of the detected abnormal state. The abnormality notification device 1 transmits information on an abnormal state determined to notify the management base station M to the management base station M. Further, the abnormality notification device 1 determines whether or not to notify the driver who drives the vehicle T of the abnormal state based on the content of the detected abnormal state. The abnormality notification device 1 transmits information on an abnormal state determined to be notified to the driver to the driver.
［車両Ｔが備えるセンサ系の概略］
　図２は、車両Ｔが備えるセンサ系２の概念図である。センサ系２は、複数のセンサＳ１～Ｓ５と、ＥＣＵ２０と、通信部２１と、報知器２２とを含む。複数のセンサＳ１～Ｓ５は、車両Ｔを構成する各部品に設けられている。センサ系２が備えるセンサの種類には、例えば、空気流量センサＳ１、加速度センサＳ２、温度センサＳ３、圧力センサＳ４及び酸素センサＳ５等がある。それらセンサは、例えば、車両を構成する部品の位置、状態及び挙動に関する情報を取得して無線又は有線で接続されたＥＣＵ（Electronic Control Unit）２０に通知する。 [Outline of sensor system provided in vehicle T]
FIG. 2 is a conceptual diagram of the sensor system 2 provided in the vehicle T. The sensor system 2 includes a plurality of sensors S1 to S5, an ECU 20, a communication unit 21, and a notification device 22. The plurality of sensors S1 to S5 are provided in each part constituting the vehicle T. Examples of the sensor provided in the sensor system 2 include an air flow rate sensor S1, an acceleration sensor S2, a temperature sensor S3, a pressure sensor S4, and an oxygen sensor S5. These sensors acquire, for example, information on the positions, states, and behaviors of the parts constituting the vehicle, and notify the ECU (Electronic Control Unit) 20 connected wirelessly or by wire.
　ＥＣＵ２０は、ＣＰＵ（Central Processing Unit）、ＲＯＭ（Read Only Memory）、ＲＡＭ（Random Access Memory）、入力ポート、出力ポート等を備えている。ＥＣＵ２０は、各センサが計測したデータをセンサが計測した時刻と関連付けてＲＡＭに記憶する。ＥＣＵ２０は、上記複数のセンサと通信を行うことによって車両Ｔのフィードバック制御を行う。換言すると、ＥＣＵ２０は、センサから取得したデータに基づいて、上記車両Ｔを構成する部品を制御し、各部品の目標値の運動状態を実現する。 The ECU 20 includes a CPU (Central Processing Unit), a ROM (Read Only Memory), a RAM (Random Access Memory), an input port, an output port, and the like. The ECU 20 stores the data measured by each sensor in the RAM in association with the time measured by the sensor. The ECU 20 performs feedback control of the vehicle T by communicating with the plurality of sensors. In other words, the ECU 20 controls the parts constituting the vehicle T based on the data acquired from the sensors, and realizes the motion state of the target value of each part.
　したがって、センサが取得する実測値とＥＣＵ２０が実現しようとする目標値との間に乖離がある場合、車両Ｔにはなんらかの異常が発生していることが疑われる。例えば、排ガス中の酸素濃度をモニタする酸素センサＳ５が、目標値よりも大きな値をＥＣＵ２０に通知した場合、インジェクタから燃料が漏れるなどして、空燃比がリーン状態となる不具合が起きている可能性がある。ＥＣＵ２０は、通信部２１を介して、このような不具合が起きたことを示す情報を異常通知装置１に送信する。このようにして、車両Ｔの管理者は、各センサが取得するデータを収集し、解析することによって車両Ｔの異常状態を発見又は予測することができる。ＥＣＵ２０は、ＥＣＵ２０がＲＡＭに記憶した各センサの計測値を、通信部２１を介して、データ収集センターＣが備える異常通知装置１へ所定の時間間隔で送信する。 Therefore, if there is a difference between the actual measurement value acquired by the sensor and the target value to be realized by the ECU 20, it is suspected that some abnormality has occurred in the vehicle T. For example, when the oxygen sensor S5 that monitors the oxygen concentration in the exhaust gas notifies the ECU 20 of a value larger than the target value, there is a possibility that the air-fuel ratio becomes lean due to fuel leaking from the injector. There is sex. The ECU 20 transmits information indicating that such a failure has occurred to the abnormality notification device 1 via the communication unit 21. In this way, the manager of the vehicle T can discover or predict an abnormal state of the vehicle T by collecting and analyzing data acquired by each sensor. ECU20 transmits the measured value of each sensor which ECU20 memorize | stored in RAM to the abnormality notification apparatus 1 with which the data collection center C is provided via the communication part 21 at a predetermined time interval.
　異常通知装置１は、所定の時間間隔で車両Ｔから受信した車両Ｔの状態を示すデータに基づいて、車両Ｔの異常を検出する。異常通知装置１は、検出した車両Ｔの異常のうち、車両Ｔの運転者に通知すると判定した異常状態の情報を車両Ｔに送信する。異常通知装置１から異常状態の情報を通知された車両ＴのＥＣＵ２０は、ＥＣＵ２０と接続された報知器２２に警告させる。車両Ｔの運転者は、例えば、警告ブザーや警告ランプといった報知器２２が発する警告を確認することによって車両Ｔの異常状態を把握することができる。 The abnormality notification device 1 detects an abnormality of the vehicle T based on data indicating the state of the vehicle T received from the vehicle T at a predetermined time interval. The abnormality notification device 1 transmits, to the vehicle T, information on an abnormal state determined to be notified to the driver of the vehicle T among the detected abnormalities of the vehicle T. The ECU 20 of the vehicle T that is notified of the abnormal state information from the abnormality notification device 1 causes the alarm device 22 connected to the ECU 20 to warn. The driver of the vehicle T can grasp the abnormal state of the vehicle T by confirming a warning issued by the alarm 22 such as a warning buzzer or a warning lamp.
［異常通知装置１の構成］
　図３は、異常通知装置１の構成を示す図である。異常通知装置１は、記憶部１０、第１通信部１１、第２通信部１２及び制御部１３を有する。 [Configuration of Abnormality Notification Device 1]
FIG. 3 is a diagram illustrating a configuration of the abnormality notification device 1. The abnormality notification device 1 includes a storage unit 10, a first communication unit 11, a second communication unit 12, and a control unit 13.
　記憶部１０は、例えば、作業用記憶媒体として機能するＲＡＭ（Random Access Memory）、制御部１３が実行するプログラムが記録されたＲＯＭ（Read Only Memory）及び車両Ｔから受信したデータを記録するＨＤＤ（Hard Disk Drive）を含む。記憶部１０は、各車両Ｔに用いられた部品の製品番号、車両Ｔの車種、運転者、所有者名等を記憶している。記憶部１０は、異常通知装置１が検出した車両Ｔの異常状態の内容、異常通知装置１が異常状態を検出した日時、異常通知装置１が車両Ｔの運転者及び管理基地局Ｍへ通知した履歴を記憶してもよい。また、記憶部１０は、異常通知装置１が車両の異常状態を検出するための各種データも記憶している。 The storage unit 10 includes, for example, a RAM (Random Access Memory) functioning as a working storage medium, a ROM (Read Only Memory) in which a program executed by the control unit 13 is recorded, and an HDD (Recording Data received from the vehicle T). Hard Disk Drive). The storage unit 10 stores the product number of the parts used for each vehicle T, the vehicle type of the vehicle T, the driver, the owner name, and the like. The storage unit 10 reports the contents of the abnormal state of the vehicle T detected by the abnormality notification device 1, the date and time when the abnormality notification device 1 detects the abnormal state, and the abnormality notification device 1 notifies the driver of the vehicle T and the management base station M. A history may be stored. The storage unit 10 also stores various data for the abnormality notification device 1 to detect an abnormal state of the vehicle.
　第１通信部１１は、複数の車両Ｔと無線通信回線を介してデータを送受信する。第１通信部１１は、複数の車両Ｔのそれぞれから送られてくる各種センサが取得したデータを受信する。第１通信部１１は、受信したデータを制御部１３に通知する。また、第１通信部１１は、異常通知装置１が検出した車両Ｔの異常状態のうち、車両Ｔの運転者へ通知する必要がある異常状態の情報を車両Ｔへ送信する。 The first communication unit 11 transmits / receives data to / from a plurality of vehicles T via wireless communication lines. The first communication unit 11 receives data acquired by various sensors sent from each of the plurality of vehicles T. The first communication unit 11 notifies the control unit 13 of the received data. Moreover, the 1st communication part 11 transmits the information of the abnormal condition which needs to be notified to the driver | operator of the vehicle T among the abnormal conditions of the vehicle T which the abnormality notification apparatus 1 detected to the vehicle T.
　第２通信部１２は、例えば、管理基地局Ｍへインターネット回線を介してデータを送信する。第２通信部１２は、異常通知装置１が検出した車両Ｔの異常状態のうち、車両Ｔの所有者へ通知する必要がある異常状態の情報を管理基地局Ｍへ通知する。 The second communication unit 12 transmits data to the management base station M via the Internet line, for example. The second communication unit 12 notifies the management base station M of information on the abnormal state that needs to be notified to the owner of the vehicle T among the abnormal states of the vehicle T detected by the abnormality notification device 1.
　制御部１３は、例えば、ＣＰＵ（Central Processing Unit）であり、記憶部１０に記録されたプログラムを実行することにより、第１通信部１１及び第２通信部１２を含む各種ハードウェアを制御する。また、制御部１３は、情報取得部１００、異常検出部１１０、判定部１２０及び異常通知部１３０としても機能する。 The control unit 13 is a CPU (Central Processing Unit), for example, and controls various hardware including the first communication unit 11 and the second communication unit 12 by executing a program recorded in the storage unit 10. The control unit 13 also functions as the information acquisition unit 100, the abnormality detection unit 110, the determination unit 120, and the abnormality notification unit 130.
　情報取得部１００は、第１通信部が複数の車両Ｔから受信した車両の状態を示す状態情報を取得する。情報取得部１００は、上記状態情報の取得を所定の時間間隔（例えば、１２分毎に４０秒間）で行う。情報取得部１００が取得する状態情報は、上述した車両Ｔに備えられた各種センサが取得するデータを含む。また、情報取得部１００は、車両Ｔの位置を示すＧＰＳ座標を取得してもよい。情報取得部１００は、第１通信部から取得した各種データを車両Ｔの個体番号と関連付けて記憶部１０に記録し、車両Ｔの状態情報を更新したことを異常検出部１１０に通知する。 The information acquisition unit 100 acquires state information indicating the state of the vehicle received by the first communication unit from the plurality of vehicles T. The information acquisition unit 100 acquires the state information at a predetermined time interval (for example, every 12 minutes for 40 seconds). The state information acquired by the information acquisition unit 100 includes data acquired by various sensors included in the vehicle T described above. Further, the information acquisition unit 100 may acquire GPS coordinates indicating the position of the vehicle T. The information acquisition unit 100 records various data acquired from the first communication unit in the storage unit 10 in association with the individual number of the vehicle T, and notifies the abnormality detection unit 110 that the state information of the vehicle T has been updated.
　異常検出部１１０は、情報取得部１００が取得した状態情報に基づいて車両Ｔの異常状態を検出する。異常検出部１１０は、情報取得部１００から車両Ｔの状態情報を取得したことを通知されると、記憶部１０に記録されている更新されたデータを参照し、車両Ｔの異常を検出する。異常検出部１１０は、例えば、センサの計測値の経時的変化に基づいて、車両Ｔの異常状態を検出する。また、異常検出部１１０は、予め記憶部１０に記録された車両Ｔが異常状態である場合のデータと照合することによって、車両Ｔの異常状態を検出してもよい。異常検出部１１０は、車両Ｔの異常を検出した場合、異常の内容及びセンサが異常値を取得した時刻を記憶部１０に記録する。異常検出部１１０は、検出した車両Ｔの異常状態の内容を判定部１２０へ通知する。 The abnormality detection unit 110 detects the abnormal state of the vehicle T based on the state information acquired by the information acquisition unit 100. When notified from the information acquisition unit 100 that the state information of the vehicle T has been acquired, the abnormality detection unit 110 refers to the updated data recorded in the storage unit 10 and detects an abnormality in the vehicle T. The abnormality detection unit 110 detects an abnormal state of the vehicle T based on, for example, a change with time in the measurement value of the sensor. Further, the abnormality detection unit 110 may detect the abnormal state of the vehicle T by collating with data when the vehicle T recorded in the storage unit 10 in advance is in an abnormal state. When the abnormality detection unit 110 detects an abnormality in the vehicle T, the abnormality detection unit 110 records the content of the abnormality and the time when the sensor acquires the abnormal value in the storage unit 10. The abnormality detection unit 110 notifies the determination unit 120 of the content of the detected abnormal state of the vehicle T.
　判定部１２０は、異常検出部１１０が検出した異常状態の内容に基づいて、車両Ｔを管理する管理基地局Ｍに異常状態を通知するか否かを判定する。判定部１２０は、例えば、記憶部１０に記録された、管理基地局Ｍに通知すべき異常状態と車両Ｔの運転者に通知すべき異常状態とを示すデータベースを参照して、上記判定をする。具体的には、判定部１２０は、以下の各種の条件のいずれかに基づいて、異常状態を管理基地局Ｍに通知するか否かを判定する。 The determination unit 120 determines whether to notify the management base station M that manages the vehicle T of the abnormal state based on the content of the abnormal state detected by the abnormality detection unit 110. The determination unit 120 makes the above determination with reference to, for example, a database recorded in the storage unit 10 and indicating an abnormal state to be notified to the management base station M and an abnormal state to be notified to the driver of the vehicle T. . Specifically, the determination unit 120 determines whether to notify the management base station M of the abnormal state based on any of the following various conditions.
　また、判定部１２０は、記憶部１０に記録されている車両Ｔの異常状態の履歴に基づいて、上記判定をしてもよい。判定部１２０は、例えば、異常検出部１１０が過去に所定の回数以上、同じ内容の異常状態を検出したことが記憶部１０に記録されている場合、車両Ｔの異常を管理基地局Ｍへ通知する。また、判定部１２０は、重大な異常が発生した他の車両Ｔの異常状態の履歴と類似する異常状態が発生した場合、管理基地局Ｍに通知する。 Further, the determination unit 120 may make the above determination based on the history of the abnormal state of the vehicle T recorded in the storage unit 10. The determination unit 120 notifies the management base station M of an abnormality in the vehicle T, for example, when the abnormality detection unit 110 records in the storage unit 10 that an abnormality state having the same content has been detected a predetermined number of times in the past. To do. Further, the determination unit 120 notifies the management base station M when an abnormal state similar to the abnormal state history of another vehicle T in which a serious abnormality has occurred.
　判定部１２０は、例えば、車両が走行できない状態になると推定した場合、異常状態を管理基地局Ｍに通知すると判定する。例えば、判定部１２０は、異常状態が発生した時点から車両Ｔが走行できなくなるまでに経過した時間の統計情報に基づいて、車両Ｔが走行できない状態になると推定する。具体的には、判定部１２０は、過去に同じ異常状態が発生してから所定の時間内に走行できなくなった車両Ｔの割合が閾値よりも大きい場合、異常状態を管理基地局Ｍに通知すると判定する。判定部１２０は、情報取得部１００が取得する車両Ｔの状態を示すデータが経時的に悪化しており、且つ、車両Ｔの状態を示すデータの変化度合いから所定の期間内に車両Ｔが走行できなくなると考えられる場合、車両Ｔが走行できない状態になると推定してもよい。具体的には、判定部１２０は、車両Ｔに備えられたセンサが取得する実測値とＥＣＵが実現しようとする目標値との乖離が経時的に大きくなっていることがわかる場合、車両Ｔの異常状態は悪化する可能性が高いため、車両が走行できない状態になると推定する。 The determination unit 120 determines to notify the management base station M of an abnormal state, for example, when it is estimated that the vehicle is not allowed to travel. For example, the determination unit 120 estimates that the vehicle T is in a state in which it cannot travel based on statistical information of the time that has elapsed since the abnormal state has occurred until the vehicle T cannot travel. Specifically, the determination unit 120 notifies the management base station M of the abnormal state when the ratio of the vehicle T that has become unable to travel within a predetermined time since the same abnormal state has occurred in the past is greater than a threshold value. judge. In the determination unit 120, the data indicating the state of the vehicle T acquired by the information acquisition unit 100 has deteriorated over time, and the vehicle T travels within a predetermined period from the degree of change in the data indicating the state of the vehicle T. When it is considered that the vehicle cannot be used, it may be estimated that the vehicle T is in a state where it cannot travel. Specifically, when the determination unit 120 finds that the difference between the actual measurement value acquired by the sensor provided in the vehicle T and the target value to be realized by the ECU increases over time, the determination unit 120 Since the abnormal state is likely to deteriorate, it is estimated that the vehicle cannot travel.
　判定部１２０は、異常検出部１１０が検出した異常状態が所定の時間以内に解消した場合、異常状態を管理基地局Ｍに通知しないと判定してもよい。例えば、判定部１２０は、異常検出部１１０から異常を検出したことを通知されてから、直ちに管理基地局Ｍ又は車両Ｔの運転者に車両Ｔの異常状態を通知せずに、所定の時刻（例えば、車両Ｔの運転を終了する時刻）又は所定の時間経過後（例えば、３０分後）に、管理基地局Ｍ又は車両Ｔの運転者に車両Ｔの異常状態を通知する。この場合、判定部１２０は、異常検出部１１０が車両Ｔから取得した新たなデータから異常を検出しなかった場合、管理基地局Ｍ又は車両Ｔの運転者に車両Ｔの異常状態を通知することをとりやめることで、重大でない一時的な異常状態を管理基地局Ｍ又は車両Ｔの運転者に通知してしまうことを回避できる。 The determination unit 120 may determine not to notify the management base station M of the abnormal state when the abnormal state detected by the abnormality detection unit 110 is resolved within a predetermined time. For example, the determination unit 120 is notified of the abnormality detected by the abnormality detection unit 110 and immediately after notifying the driver of the management base station M or the vehicle T of the abnormal state of the vehicle T at a predetermined time ( For example, the management base station M or the driver of the vehicle T is notified of the abnormal state of the vehicle T after a lapse of a predetermined time (for example, after 30 minutes). In this case, the determination unit 120 notifies the management base station M or the driver of the vehicle T of the abnormal state of the vehicle T when the abnormality detection unit 110 does not detect the abnormality from the new data acquired from the vehicle T. By canceling, it is possible to avoid notifying the driver of the management base station M or the vehicle T of a non-critical temporary abnormal state.
　判定部１２０は、車両Ｔが所定の位置にある場合と、所定の位置にない場合とで、異なる判定基準に基づいて異常状態を管理基地局Ｍに通知するか否かを判定してもよい。判定部１２０は、例えば、車両ＴのＧＰＳ座標が整備工場の位置を示している場合、通常より厳しい判定基準に基づいて異常状態を管理基地局Ｍに通知する。こうすると、将来、重大な異常が発生する可能性がある部位を、重大な異常が発生する前に修理することができる。したがって、車両Ｔの所有者は、走行中に車両Ｔに異常が発生するのを防ぐことができる。 The determination unit 120 may determine whether or not to notify the management base station M of an abnormal state based on different determination criteria depending on whether the vehicle T is at a predetermined position or not. . For example, when the GPS coordinates of the vehicle T indicate the position of the maintenance shop, the determination unit 120 notifies the management base station M of an abnormal state based on a criterion that is stricter than usual. In this way, a part where a serious abnormality may occur in the future can be repaired before the serious abnormality occurs. Therefore, the owner of the vehicle T can prevent an abnormality from occurring in the vehicle T during traveling.
　異常通知部１３０は、判定部１２０が管理基地局Ｍに通知すると判定した異常状態を管理基地局Ｍに送信し、判定部１２０が管理基地局Ｍに通知しないと判定した異常状態を車両Ｔに通知してもよい。具体的には、異常通知部１３０は、異常が発生した車両Ｔの識別情報と、当該車両Ｔを管理している管理基地局Ｍのコンピュータのアドレスと、異常が発生した旨と、を含む異常通知メッセージを作成して、第２通信部１２を介して送信することにより、管理基地局Ｍのコンピュータに異常が発生したことを通知する。 The abnormality notification unit 130 transmits the abnormal state determined by the determination unit 120 to notify the management base station M to the management base station M, and notifies the vehicle T of the abnormal state determined by the determination unit 120 not to notify the management base station M. You may be notified. Specifically, the abnormality notification unit 130 includes an abnormality including identification information of the vehicle T in which the abnormality has occurred, the address of the computer of the management base station M that manages the vehicle T, and the fact that the abnormality has occurred. A notification message is created and transmitted via the second communication unit 12 to notify the computer of the management base station M that an abnormality has occurred.

［本実施形態の異常通知装置１による効果］
　以上説明したように、異常通知装置１は、車両Ｔの状態を示す状態情報を取得し、状態情報に基づいて車両Ｔの異常状態を検出し、検出した異常状態の内容に基づいて、車両Ｔを管理する管理基地局Ｍに異常状態を通知するか否かを判定する。異常通知装置１は、管理基地局に通知すると判定した異常状態を管理基地局Ｍに送信し、管理基地局Ｍに通知しないと判定した異常状態を車両Ｔに通知する。このようにすると、異常通知装置１は、検出した全ての車両Ｔの異常状態を管理基地局Ｍへ通知しないため、管理基地局Ｍの負担を軽減することができる。 [Effects of the abnormality notification device 1 of the present embodiment]
As described above, the abnormality notification device 1 acquires the state information indicating the state of the vehicle T, detects the abnormal state of the vehicle T based on the state information, and based on the content of the detected abnormal state, the vehicle T It is determined whether or not to notify the management base station M that manages the abnormal state. The abnormality notification device 1 transmits the abnormal state determined to be notified to the management base station to the management base station M, and notifies the vehicle T of the abnormal state determined not to be notified to the management base station M. If it does in this way, since the abnormality notification apparatus 1 does not notify the management base station M of the abnormal state of all the detected vehicles T, it can reduce the burden of the management base station M.
　異常通知装置１は、車両Ｔが走行できない状態になると推定した場合、異常状態を管理基地局Ｍに通知すると判定する。こうすると、車両Ｔの所有者は、車両Ｔが走行できなくなる前に、車両Ｔの異常状態を把握することができる。車両Ｔの所有者は、車両Ｔの異常を早い段階で修復することにより、車両Ｔの走行中に異常が発生することを防ぐことができるので、車両Ｔの運転を継続させることができる。 The abnormality notification device 1 determines to notify the management base station M of the abnormal state when it is estimated that the vehicle T is in a state where it cannot travel. In this way, the owner of the vehicle T can grasp the abnormal state of the vehicle T before the vehicle T can no longer travel. The owner of the vehicle T can prevent the abnormality from occurring during the traveling of the vehicle T by repairing the abnormality of the vehicle T at an early stage, so that the operation of the vehicle T can be continued.
　異常通知装置１は、検出した異常状態が所定の時間以内に解消した場合、異常状態を管理基地局Ｍに通知しないと判定する。こうすることによって、重要でない異常状態が管理基地局Ｍに通報され、管理基地局Ｍの職員が対応に時間を取られたり、重要でない異常であるにもかかわらず車両Ｔの運転を停止させたりすることを防止できる。 The abnormality notification device 1 determines that the abnormal state is not notified to the management base station M when the detected abnormal state is resolved within a predetermined time. By doing so, an unimportant abnormal state is notified to the management base station M, and the staff of the management base station M takes time to respond, or the operation of the vehicle T is stopped even though the abnormality is not important. Can be prevented.
　異常通知装置１は、車両Ｔが所定の位置にある場合と、所定の位置にない場合とで、異なる判定基準に基づいて異常状態を管理基地局Ｍに通知するか否かを判定する。こうすると、異常通知装置１は、車両Ｔが整備工場にあるときは、通常より厳しい判定基準で異常状態を検出するため、将来、重大な異常が発生する可能性がある部位を、重大な異常が発生する前に修理することができる。したがって、車両Ｔの走行中に異常が発生し、車両Ｔが走行できなく可能性を低減できる。 The abnormality notification device 1 determines whether to notify the management base station M of an abnormal state based on different determination criteria depending on whether the vehicle T is at a predetermined position or not. In this way, when the vehicle T is in the maintenance shop, the abnormality notification device 1 detects an abnormal state based on a criterion that is stricter than usual, so that a region where a serious abnormality may occur in the future is detected. Can be repaired before it occurs. Therefore, an abnormality occurs while the vehicle T is traveling, and the possibility that the vehicle T cannot travel can be reduced.
＜第２の実施形態＞
　第１の実施形態においては、データ収集センターＣに設置された異常通知装置１において、車両Ｔの異常を検出したが、車両Ｔが、第１の実施形態の異常通知装置１と同等の異常検出手段を有し、車両Ｔにおいて車両Ｔの異常を検出してもよい。この場合、車両Ｔの異常検出手段が異常を検出した場合、車両Ｔの異常検出手段は、異常が発生したことをインスツルメントパネルに表示して運転者に通知したり、管理基地局Ｍに異常の発生を通報したりする。 <Second Embodiment>
In the first embodiment, the abnormality notification device 1 installed in the data collection center C detects an abnormality of the vehicle T. However, the vehicle T detects an abnormality equivalent to the abnormality notification device 1 of the first embodiment. An abnormality of the vehicle T in the vehicle T may be detected.
