車両用管理システムVehicle management system
　本発明は、車両用管理システムに関し、特に、内燃機関から排出される排気中の粒子状物質（以下、ＰＭ）を捕集するフィルタ（以下、ＤＰＦという）を備えた排気浄化装置を搭載する車両の管理システムに関する。 The present invention relates to a vehicle management system, and in particular, a vehicle equipped with an exhaust purification device including a filter (hereinafter referred to as DPF) that collects particulate matter (hereinafter referred to as PM) in exhaust discharged from an internal combustion engine. Related to the management system.
　従来、複数台の車両を所有する運送業者等の管理用端末に各車両の運行データを送信して運行状況を通知することで、運行管理の向上を図るシステムが開発されている（例えば、特許文献１参照）。 Conventionally, a system has been developed that improves operation management by transmitting operation data of each vehicle to a management terminal such as a carrier that owns a plurality of vehicles to notify the operation status (for example, patents) Reference 1).
　一般的に、運送業者が所有するトラック等の車両には、ＤＰＦを備えた排気浄化装置が搭載されている。ＤＰＦは、ＰＭ捕集量に限度があるため、堆積したＰＭを定期的に燃焼除去するいわゆる強制再生を行う必要がある（例えば、特許文献２参照）。 Generally, vehicles such as trucks owned by carriers are equipped with exhaust purification devices equipped with DPFs. Since the DPF has a limit in the amount of collected PM, it is necessary to perform so-called forced regeneration in which accumulated PM is periodically burned and removed (see, for example, Patent Document 2).

　ところで、ＤＰＦに劣化や目詰まり等による故障が生じると、車両は走行不能状態になり、運送業者の運行管理に影響を及ぼす可能性がある。このような影響を事前に回避するためには、ＤＰＦに故障が生じる前に車両を入庫させて、メンテナンス等を行う必要がある。すなわち、ＤＰＦの各種機能が低下傾向を示した時点で、管理者や運転者等に知らせることが好ましい。 By the way, if a failure occurs due to deterioration or clogging in the DPF, the vehicle becomes unable to travel, which may affect the operation management of the carrier. In order to avoid such an influence in advance, it is necessary to perform maintenance or the like by placing the vehicle in the vehicle before the failure occurs in the DPF. That is, it is preferable to notify the manager, the driver, etc. when various functions of the DPF show a tendency to decrease.
　本発明の目的は、ＤＰＦの再生情報を管理者等に適宜知らせることで、運行の向上を図ることができる車両用管理システムを提供することにある。 An object of the present invention is to provide a vehicle management system capable of improving operation by appropriately notifying a manager or the like of DPF regeneration information.

　以下、添付図面に基づいて、本発明の一実施形態に係る車両用管理システムを説明する。 Hereinafter, a vehicle management system according to an embodiment of the present invention will be described with reference to the accompanying drawings.
　図１は、本実施形態の車両用管理システムが適用される車両１の概略図である。車両１には、エンジン２の排気通路３に設けられた排気浄化装置１０が搭載されている。排気浄化装置１０は、排気上流側から順に、燃料噴射装置１１、酸化触媒（以下、ＤＯＣ）１２、排気温度センサ１３、ＤＰＦ１４及び、差圧センサ１５等を備えている。 FIG. 1 is a schematic diagram of a vehicle 1 to which the vehicle management system of the present embodiment is applied. An exhaust purification device 10 provided in the exhaust passage 3 of the engine 2 is mounted on the vehicle 1. The exhaust purification device 10 includes a fuel injection device 11, an oxidation catalyst (hereinafter referred to as DOC) 12, an exhaust temperature sensor 13, a DPF 14, a differential pressure sensor 15 and the like in order from the exhaust upstream side.
　燃料噴射装置１１は、ＥＣＵから入力される指示信号に応じて、排気通路３内に未燃燃料（主にＨＣ）を噴射する。なお、エンジン２の多段噴射によるポスト噴射を用いる場合は、この燃料噴射装置１１を省略してもよい。ＤＯＣ１２は、燃料噴射装置１１又はポスト噴射によってＨＣが供給されると、これを酸化して排気温度を上昇させる。ＤＰＦ１４は、排気中のＰＭを隔壁表面に捕集すると共に、ＰＭ堆積量が所定量に達すると、これを燃焼除去するいわゆる強制再生が実行される。強制再生は、燃料噴射装置１１又はポスト噴射によってＤＯＣ１２に未燃燃料を供給し、ＤＰＦ１４に流入する排気温度をＰＭ燃焼温度まで昇温することで行われる。 The fuel injection device 11 injects unburned fuel (mainly HC) into the exhaust passage 3 in response to an instruction signal input from the ECU. In addition, when using the post injection by the multistage injection of the engine 2, this fuel injection device 11 may be omitted. When HC is supplied by the fuel injection device 11 or post injection, the DOC 12 oxidizes this and raises the exhaust gas temperature. The DPF 14 collects PM in the exhaust gas on the surface of the partition wall, and when the amount of accumulated PM reaches a predetermined amount, so-called forced regeneration is performed to remove the PM. The forced regeneration is performed by supplying unburned fuel to the DOC 12 by the fuel injection device 11 or post injection, and raising the exhaust temperature flowing into the DPF 14 to the PM combustion temperature.
　本実施形態の排気浄化装置１０は、強制再生として、「自動再生」及び、「手動再生」を実行可能に構成されている。自動再生とは、車両１の走行距離が所定距離に達した場合、差圧センサ１５によって検出されるＤＰＦ前後差圧が所定閾値に達した場合又は、各種センサ等がＤＰＦ１４の再生時期を検出した場合に自動的に開始される再生をいう。手動再生とは、車両１を停車させて運転者が操作ボタン（不図示）をＯＮ操作することにより開始される再生をいう。この手動再生には、運転室の表示パネルに手動再生マークＭを点滅させて運転者に手動再生を促すことで実行される受動的な手動再生及び、手動再生マークＭが点滅していない状態で実行される任意の手動再生が含まれる。 The exhaust purification device 10 of the present embodiment is configured to be able to execute “automatic regeneration” and “manual regeneration” as forced regeneration. Automatic regeneration refers to when the travel distance of the vehicle 1 reaches a predetermined distance, when the differential pressure across the DPF detected by the differential pressure sensor 15 reaches a predetermined threshold, or when various sensors detect the regeneration timing of the DPF 14. A playback that starts automatically in some cases. Manual regeneration refers to regeneration started when the vehicle 1 is stopped and the driver turns on an operation button (not shown). In this manual regeneration, the manual regeneration mark M blinks on the display panel of the cab and the driver is prompted to perform manual regeneration, and the manual regeneration mark M is not blinking.

The vehicle-side terminal device 20 and the management-side terminal device 40 are connected so as to be capable of wireless communication via a network N such as a mobile phone line. A base station (not shown) that functions as a server may be provided between the vehicle-side terminal device 20 and the management-side terminal device 40. In this case, the base station and the management-side terminal device 40 may be connected via the Internet or the like, and data may be transmitted from the base station in response to a request from the management-side terminal device 40.
　車両側端末装置２０は、再生情報取得蓄積部２１と、データ送信部２２とを備えている。なお、図示例では、一台の車両１のみを示しているが、複数台を管理する場合は各車両毎に車両側端末装置２０を搭載すればよい。 The vehicle-side terminal device 20 includes a reproduction information acquisition / storage unit 21 and a data transmission unit 22. In the illustrated example, only one vehicle 1 is shown. However, when managing a plurality of vehicles, the vehicle-side terminal device 20 may be mounted for each vehicle.
　再生情報取得蓄積部２１は、以下（１）～（６）に示す再生情報を取得してデータとして蓄積する。（１）自動・手動再生が開始された車両１の走行距離、（２）自動再生・手動再生に要した再生時間、（３）自動再生・手動再生の再生完了、（４）自動再生・手動再生の再生未完了、（５）自動再生・手動再生の再生中断、（６）ＰＭ除去エラー。 The reproduction information acquisition / storage unit 21 acquires the reproduction information shown in the following (1) to (6) and stores it as data.

　再生完了とは、例えば、自動再生又は手動再生の実行期間中にＰＭの燃焼除去に必要な所定期間、ＤＰＦ入口温度をＰＭ燃焼温度以上で維持できた場合をいう。再生未完了とは、例えば、自動再生又は手動再生の実行期間中にＰＭの燃焼除去に必要な所定期間、ＤＰＦ入口温度をＰＭ燃焼温度以上で維持できなかった場合をいう。再生中断とは、自動再生又は手動再生実行中にイグニッションキーＯＦＦ操作やアイドリングストップ等によって、再生が一時的に中断した場合をいう。ＰＭ除去エラーとは、自動再生終了時又は手動再生終了時のＤＰＦ前後差圧が所定の閾値以上であって、ＤＰＦ１４の再生が失敗に終わった場合をいう。 “Regeneration completion” refers to, for example, a case where the DPF inlet temperature can be maintained at or above the PM combustion temperature for a predetermined period required for PM combustion removal during the execution period of automatic regeneration or manual regeneration. Regeneration incomplete means, for example, a case where the DPF inlet temperature cannot be maintained at the PM combustion temperature or higher for a predetermined period required for PM combustion removal during the execution period of automatic regeneration or manual regeneration. The reproduction interruption is a case where reproduction is temporarily interrupted by an ignition key OFF operation, idling stop or the like during execution of automatic reproduction or manual reproduction. The PM removal error refers to a case where the differential pressure across the DPF at the end of automatic regeneration or at the end of manual regeneration is greater than or equal to a predetermined threshold value and regeneration of the DPF 14 has failed.
　データ送信部２２は、再生情報取得蓄積部２１に蓄積された各種再生情報データを無線送信する。再生情報データを送信するタイミングは任意に設定可能であり、例えば、１日に１回又は数回送信してもよく、リアルタイムで送信することも可能である。 The data transmission unit 22 wirelessly transmits various reproduction information data stored in the reproduction information acquisition / storage unit 21. The timing for transmitting the reproduction information data can be arbitrarily set. For example, the reproduction information data may be transmitted once or several times a day, or may be transmitted in real time.
　管理側端末装置４０は、データ送信部２２から送信される再生情報データを受信するデータ受信部４１と、各種診断を行う再生状態診断部４２と、各種再生情報データ及び、診断結果を表示する表示部４３とを備えている。 The management-side terminal device 40 includes a data reception unit 41 that receives reproduction information data transmitted from the data transmission unit 22, a reproduction state diagnosis unit 42 that performs various diagnoses, a display that displays various reproduction information data and diagnosis results. Part 43.
　再生状態診断部４２は、データ受信部４１によって受信された再生情報データに基づいて、ＰＭ捕集機能、ＤＰＦ再生機能、自動再生機能、ＰＭ酸化除去機能及び、ＰＭ酸化効率の各種機能診断を実行する。以下、これら各診断項目の詳細について説明する。なお、各種機能診断に用いられる「低下傾向」とは、当該機能の故障によって車両１が走行不能となるよりも前の状態を意味する。 Based on the reproduction information data received by the data receiving unit 41, the reproduction state diagnosis unit 42 performs various function diagnosis of the PM collection function, the DPF regeneration function, the automatic regeneration function, the PM oxidation removal function, and the PM oxidation efficiency. To do. Details of each of these diagnostic items will be described below. The “decreasing tendency” used for various function diagnosis means a state before the vehicle 1 becomes unable to travel due to a failure of the function.
　［ＰＭ捕集機能診断］
　ＰＭ捕集機能は、自動再生終了から次の自動再生開始までの走行距離（以下、再生インターバルという）に基づいて診断される。例えば、図３（Ａ）に示すように、直近１０回分の再生インターバル平均値が正常時のインターバル以上の場合、ＰＭ捕集機能は「良好」と診断される。 [PM collection function diagnosis]
The PM collection function is diagnosed based on a travel distance from the end of automatic regeneration to the start of the next automatic regeneration (hereinafter referred to as a regeneration interval). For example, as shown in FIG. 3A, when the average value of the reproduction intervals for the latest 10 times is equal to or greater than the normal interval, the PM collection function is diagnosed as “good”.
　一方、図３（Ｂ）に示すように、直近１０回分の再生インターバル平均値が継続して正常時のインターバルよりも短い場合、ＰＭ捕集機能は「低下傾向」と診断される。このような状態は、アッシュの堆積によってＤＰＦ１４のＰＭ捕集機能が著しく低下していると考えられるためである。なお、直近１０回の自動再生の間に任意の手動再生が実行された場合は、ＰＭ捕集機能の回復が期待されるため、当該診断から除外してもよい。 On the other hand, as shown in FIG. 3B, when the average value of the reproduction intervals for the latest 10 times is continuously shorter than the normal interval, the PM trapping function is diagnosed as “decreasing tendency”. This is because it is considered that the PM trapping function of the DPF 14 is significantly lowered due to the accumulation of ash. Note that if any manual regeneration is executed during the last 10 automatic regenerations, recovery of the PM collection function is expected, so it may be excluded from the diagnosis.
　［ＤＰＦ再生機能診断］
　ＤＰＦ再生機能は、直近数回分の自動再生（手動再生を含む）において、再生完了に対する再生未完了の発生頻度が増加したか否かに基づいて診断される。例えば、図４（Ａ）に示すように、直近１０回の自動再生又は手動再生において、再生未完了の発生がｎ回（但し、ｎ＜１０）以下の場合に、ＤＰＦ再生機能は「良好」と診断される。 [DPF regeneration function diagnosis]
The DPF regeneration function is diagnosed based on whether or not the frequency of uncompleted regeneration with respect to regeneration completion has increased in the most recent automatic regeneration (including manual regeneration). For example, as shown in FIG. 4A, the DPF regeneration function is “good” when regeneration incomplete has occurred n times (where n <10) or less in the last 10 automatic regenerations or manual regenerations. Is diagnosed.
　一方、図４（Ｂ）に示すように、直近１０回の自動再生又は手動再生において、再生未完了が非連続にｎ回以上（但し、ｎ＜１０）発生した場合に、ＤＰＦ再生機能は「低下傾向」と診断される。このような状態は、ＤＯＣ１２の劣化により排気温度がＰＭ燃焼温度まで昇温されていないか、あるいは、燃料噴射装置１１の不調等により排気管内噴射が行えていない可能性が考えられるためである。なお、直近５回の自動再生又は手動再生において、再生未完了が発生していない場合は、ＤＰＦ再生機能の回復が期待されるため、当該診断から除外してもよい。 On the other hand, as shown in FIG. 4B, in the last 10 automatic regenerations or manual regenerations, when incomplete regeneration has occurred n times or more (however, n <10), the DPF regeneration function is “ Diagnosed as “declining trend”. This is because there is a possibility that the exhaust temperature has not been raised to the PM combustion temperature due to the deterioration of the DOC 12 or that the in-pipe injection cannot be performed due to the malfunction of the fuel injection device 11 or the like. It should be noted that in the most recent five automatic regenerations or manual regenerations, if regeneration incomplete has not occurred, recovery of the DPF regeneration function is expected, so it may be excluded from the diagnosis.
　［自動再生機能診断］
　自動再生機能は、直近数回分の再生において、手動再生マークＭの点滅時に実行された手動再生の頻度に基づいて診断される。例えば、図５に示すように、直近１０回の再生のうち、手動再生マークＭ点滅時に実行された手動再生がｎ回以上（但し、ｎ＜１０）発生した場合に、自動再生機能は「低下傾向」と診断される。このような状態は、自動再生によってもＰＭの燃焼除去が進まず、手動再生マークＭの点滅により手動再生が頻繁に促されたと考えられるためである。一方、条件不成立の場合は、自動再生機能は「良好」と診断される。 [Automatic playback function diagnosis]
The automatic reproduction function is diagnosed based on the frequency of manual reproduction executed when the manual reproduction mark M blinks in the most recent reproductions. For example, as shown in FIG. 5, when the manual regeneration performed during the manual regeneration mark M blinking occurs more than n times (however, n <10) among the 10 most recent regenerations, the automatic regeneration function is “decreased”. Diagnosed as “trend”. This is because it is considered that PM regeneration is not promoted even by automatic regeneration, and manual regeneration is frequently prompted by blinking of the manual regeneration mark M. On the other hand, when the condition is not satisfied, the automatic reproduction function is diagnosed as “good”.
　［ＰＭ酸化除去機能診断］
　ＰＭ酸化除去機能は、ＰＭ除去エラーの発生頻度及び、手動再生マークＭの点滅時に実行された手動再生の頻度に基づいて診断される。例えば、図６に示すように、直近１０回の再生中において、ＰＭ除去エラーがｎ回（但し、ｎ＜１０）発生し、且つ手動再生がｎ回（但し、ｎ＜１０）行われた場合、ＰＭ酸化機能は「低下傾向」と診断される。このような状態は、自動再生や手動再生を行っても、スート成分の酸化除去が殆ど進んでいないと考えられるためである。一方、条件不成立の場合は、ＰＭ酸化除去機能は「良好」と診断される。 [PM oxidation removal function diagnosis]
The PM oxidation removal function is diagnosed based on the frequency of occurrence of PM removal errors and the frequency of manual regeneration executed when the manual regeneration mark M blinks. For example, as shown in FIG. 6, when the PM removal error has occurred n times (however, n <10) and manual regeneration has been performed n times (where n <10) during the last 10 times of playback. The PM oxidation function is diagnosed as “decreasing tendency”. This is because it is considered that oxidation removal of the soot component has hardly progressed even if automatic regeneration or manual regeneration is performed. On the other hand, when the condition is not satisfied, the PM oxidation removal function is diagnosed as “good”.
　［ＰＭ酸化効率診断］
　ＰＭ酸化効率は、自動再生又は手動再生の実行中における再生中断の発生頻度に基づいて診断される。例えば、図７に示すように、１回の自動再生（又は、手動再生）につき、再生中断が３回以上発生した場合、当該再生時のＰＭ酸化効率は「低下傾向」と診断される。このような状態は、中断の頻発によりＤＰＦ１４の温度昇温が進まず、ＰＭ酸化効率の低下を招いていると考えられるためである。一方、条件不成立の場合は、ＰＭ酸化効率は「良好」と診断される。 [PM oxidation efficiency diagnosis]
The PM oxidation efficiency is diagnosed based on the occurrence frequency of regeneration interruption during execution of automatic regeneration or manual regeneration. For example, as shown in FIG. 7, if regeneration interruption occurs three or more times for one automatic regeneration (or manual regeneration), the PM oxidation efficiency during the regeneration is diagnosed as “decreasing tendency”. This is because the temperature rise of the DPF 14 does not proceed due to frequent interruptions, and it is considered that the PM oxidation efficiency is reduced. On the other hand, when the condition is not satisfied, the PM oxidation efficiency is diagnosed as “good”.
　表示部４３は、例えばモニタであって、データ受信部４１によって受信された各種再生情報データ及び、再生状態診断部４２によって実行された各診断結果を画面表示する。以下、図８，９に基づいて、これら再生情報データ及び、診断結果の画面表示について説明する。なお、図示例では、車両一台分の画面表示を示しているが、複数台の場合は各車両毎に表示される。 The display unit 43 is, for example, a monitor, and displays various reproduction information data received by the data reception unit 41 and each diagnosis result executed by the reproduction state diagnosis unit 42 on the screen. Hereinafter, based on FIGS. 8 and 9, the reproduction information data and the screen display of the diagnosis result will be described. In addition, in the example of illustration, although the screen display for one vehicle is shown, in the case of multiple units, it is displayed for each vehicle.
　図８は、表示部４３に画面表示される各種再生情報データの一例を示している。管理者によって任意に指定された所定期間の（１）再生完了の回数、（２）再生未完了の回数、（３）ＰＭ除去エラーの回数、（４）一回の再生に対する再生中断の回数、（５）各自動再生・手動再生の開始走行距離（実行情報）及び、（６）各再生に要した再生時間が目視で容易に確認できるように表示される。 FIG. 8 shows an example of various reproduction information data displayed on the screen of the display unit 43. (1) number of completions of reproduction, (2) number of incomplete reproductions, (3) number of PM removal errors, (4) number of reproduction interruptions for one reproduction, arbitrarily specified by the administrator for a predetermined period (5) The starting travel distance (execution information) of each automatic regeneration / manual regeneration, and (6) the regeneration time required for each regeneration are displayed so that they can be easily confirmed visually.
　図９は、表示部４３に画面表示される各診断結果の一例を示している。例えば、「良好」と診断された項目についてはその旨が表示され、「低下傾向」と診断された項目についてはその旨が表示される。また、「低下傾向」と診断された項目については、メッセージも表示される。より詳しくは、ＰＭ捕集機能、ＤＰＦ再生機能、自動再生機能、ＰＭ酸化除去機能の何れか一項目でも「低下傾向」と診断された場合は、点検入庫を推奨する旨のメッセージを表示する。また、ＰＭ酸化効率が低下傾向と診断された場合は、車両１を停車させて行う任意の手動再生を推奨する旨のメッセージを表示する。なお、これら再生情報や診断結果の表示は画面表示に限定されず、印刷機による用紙出力であってもよい。 FIG. 9 shows an example of each diagnosis result displayed on the display unit 43 on the screen. For example, an item diagnosed as “good” is displayed as such, and an item diagnosed as “declining trend” is displayed as such. A message is also displayed for items diagnosed as “declining trend”. More specifically, when any one of the PM collection function, DPF regeneration function, automatic regeneration function, and PM oxidation removal function is diagnosed as “decreasing tendency”, a message that recommends inspection warehousing is displayed. Further, when it is diagnosed that the PM oxidation efficiency tends to decrease, a message indicating that any manual regeneration performed by stopping the vehicle 1 is recommended is displayed. The display of the reproduction information and the diagnosis result is not limited to the screen display, and may be paper output by a printing machine.
