Abstract

A control unit (102) determines that an outer switch (21) is faulty on the basis of the relationship between the state of the outer switch (21) and vehicle speed, specifically when the vehicle speed is greater than 0 and the outer switch (21) is in the on state. In addition, the control unit (102) determines that an inner switch (22) is faulty on the basis of the relationship of the state of the inner switch (22) and the opened-closed status of an opening-closing member (101), specifically when the opening-closing member (101) is in the closed state and the inner switch (22) is in the on state.

Description

車両のゲート開閉装置、及び、車両のゲート開閉装置における故障検出方法Vehicle gate opening and closing device, and failure detection method in vehicle gate opening and closing device
　本開示は、車両のゲート開閉装置、及び、車両のゲート開閉装置における故障検出方法に関する。 The present disclosure relates to a gate opening / closing device for a vehicle and a failure detection method in the gate opening / closing device for a vehicle.
　自動車などの車両には、車体に形成されたゲートをユーザー操作に応じてドアなどによって開閉するゲート開閉装置が設けられたものがある。例えば、ミニバンやＳＵＶ（Sport Utility Vehicle）等の車両には、その車体の後端部に、ゲートとこのゲートを開閉するバックドアとを有するテールゲート開閉装置が設けられており、このテールゲート開閉装置により車体の後端部に設けられた荷室が開閉されるようになっている。 車 両 Some vehicles, such as automobiles, are provided with a gate opening / closing device that opens / closes a gate formed on a vehicle body with a door or the like in response to a user operation. For example, vehicles such as minivans and SUVs (Sport Utility Vehicles) are provided with a tailgate opening and closing device having a gate and a back door for opening and closing the gate at the rear end of the vehicle body. The device opens and closes a luggage compartment provided at the rear end of the vehicle body.
　このようなテールゲート開閉装置のバックドアは上下方向に開閉する構造となっているため、女性や高齢者等の方にとっては、その開閉操作を容易に行えない場合がある。そこで、電動モーターを駆動源としてバックドアを自動的に開閉させるようにした電動テールゲート開閉装置が開発されている（例えば特許文献１、２参照）。 た め Since the back door of such a tailgate opening and closing device is configured to open and close in the vertical direction, it may not be easy for women and elderly people to open and close it. Accordingly, an electric tailgate opening / closing device that automatically opens and closes a back door using an electric motor as a driving source has been developed (for example, see Patent Documents 1 and 2).
　電動テールゲート開閉装置は、ユーザーによる開閉スイッチの操作状態に基づいて、バックドアを開閉駆動する駆動部を駆動させるようになっている。具体的には、開閉スイッチのうち開スイッチがユーザーによってオン操作されるとバックドアが開状態へと駆動される。逆に、開閉スイッチのうち閉スイッチがユーザーによってオン操作されるとバックドアが閉状態へと駆動される。 The electric tailgate opening and closing device drives a drive unit that opens and closes the back door based on the operation state of the opening and closing switch by the user. Specifically, when the open switch of the open / close switch is turned on by the user, the back door is driven to the open state. Conversely, when the close switch among the open / close switches is turned on by the user, the back door is driven to the closed state.

　ところで、上述のユーザー操作を受け付ける開閉スイッチが故障によりオン状態のまま固着（つまりショート）してしまう場合がある。このような固着が生じると、ユーザーが開スイッチを操作していないにもかかわらず開スイッチがオン状態となるので意図せずにバックドアが開状態となったり、ユーザーが閉スイッチを操作していないにもかかわらず閉スイッチがオン状態となるので意図せずにバックドアが閉状態となる、といった状況が起こる可能性がある。 By the way, there is a case where the open / close switch for accepting the above-mentioned user operation is fixed (that is, short-circuited) in the ON state due to a failure. If such a sticking occurs, the open switch is turned on even though the user does not operate the open switch, so that the back door is unintentionally opened or the user operates the close switch. However, there is a possibility that the back door is closed unintentionally because the close switch is turned on despite the absence of the switch.
　このような状況を未然に防ぐ一つの方法として、タイマーによって開閉スイッチのオン状態の時間的長さを監視し、開閉スイッチのオン状態が所定時間（つまりタイマー時間）以上継続した場合には、開閉スイッチの固着による故障が生じていると判断する方法がある。そして、故障と判断した場合には、開閉スイッチの操作を無効とするとともに、故障を示すアラーム表示を行う。 One way to prevent such a situation is to use a timer to monitor the length of time the on-state of the on-off switch is turned on. There is a method of determining that a failure due to the sticking of the switch has occurred. When it is determined that a failure has occurred, the operation of the open / close switch is invalidated, and an alarm indicating the failure is displayed.
　しかしながら、タイマーを用いて開閉スイッチの故障を検知する方法では、故障か否かの判断が完了するまでに少なくともタイマー時間に相当する時間がかかり、その結果、開閉スイッチによるバックドアの電動駆動を行うことができるまでにタイマー時間に相当する待ち時間が発生するといった不都合が生じる。例えばイグニッションスイッチがオン時に開閉スイッチの故障検知を開始することを想定すると、タイマー時間が５秒である場合には、イグニッションスイッチがオンされてから５秒以降でなければ開閉スイッチによるバックドアの電動駆動を行うことができない。 However, in the method of detecting the failure of the open / close switch using the timer, it takes at least a time corresponding to the timer time until the determination of the failure is completed, and as a result, the back door is electrically driven by the open / close switch. There is a disadvantage that a waiting time corresponding to the timer time occurs before the operation can be performed. For example, assuming that the detection of a failure of the open / close switch is started when the ignition switch is turned on, if the timer time is 5 seconds, the electric power of the back door by the open / close switch is not less than 5 seconds after the ignition switch is turned on. Driving cannot be performed.
　本開示は、以上の点を考慮してなされたものであり、タイマーを使わずに迅速に開閉スイッチの故障判断を行うことができる車両のゲート開閉装置、及び、車両のゲート開閉装置における故障検出方法を提供する。 The present disclosure has been made in consideration of the above points, and has a gate opening / closing device for a vehicle that can quickly determine a failure of an on / off switch without using a timer, and a failure detection in the gate opening / closing device for a vehicle.

　以下、本開示の実施の形態を、図面を参照して説明する。 Hereinafter, embodiments of the present disclosure will be described with reference to the drawings.
　本発明の発明者らは、（ｉ）アウター／インナースイッチの状態と車速との関係、又は、（ｉｉ）アウター/インナースイッチとゲートの開閉状態との関係、を用いれば、タイマーを用いずに車両のゲート開閉装置のアウター/インナースイッチが固着（つまりショート）しているか否かを検知できると考えた。 The inventors of the present invention use (i) the relationship between the state of the outer / inner switch and the vehicle speed, or (ii) the relationship between the outer / inner switch and the open / closed state of the gate, without using a timer. We thought that it was possible to detect whether the outer / inner switch of the gate opening / closing device of the vehicle was fixed (that is, short-circuited).
　以下、この考え方について説明する。図１は、車両のバックドア１０とアウタースイッチ２１及びインナースイッチ２２とを示した図である。図１Ａに示したように、アウタースイッチ２１はバックドア１０の外側に設けられている。アウタースイッチ２１は、ユーザーによって指で押し操作されるとオン状態となる。図１Ｂに示したように、インナースイッチ２２はバックドア１０の下部に設けられている。インナースイッチ２２はユーザーによって指で押し操作されるとオン状態となる。 This concept is described below. FIG. 1 is a diagram showing a back door 10, an outer switch 21, and an inner switch 22 of the vehicle. As shown in FIG. 1A, the outer switch 21 is provided outside the back door 10. The outer switch 21 is turned on when the user presses the outer switch 21 with a finger. As shown in FIG. 1B, the inner switch 22 is provided below the back door 10. When the user presses the inner switch 22 with a finger, the inner switch 22 is turned on.
　アウタースイッチ２１がオン操作されると、駆動部がバックドア１０を開状態に駆動する。逆に、インナースイッチ２２がオン操作されると、駆動部がバックドア１０を閉状態に駆動する。 と When the outer switch 21 is turned on, the driving unit drives the back door 10 to the open state. Conversely, when the inner switch 22 is turned on, the driving unit drives the back door 10 to the closed state.
　上記（ｉ）は、車両が走行中は、人が車外にあるアウタースイッチ２１を操作することができないのでアウタースイッチ２１がオン状態となるはずはない、といった着想に基づく。よって、本実施の形態では、走行中にアウタースイッチ２１がオン状態であることが検出されれば、アウタースイッチ２１は固着（つまりショート）していると判断する。 (I) The above (i) is based on the idea that the outer switch 21 cannot be turned on because a person cannot operate the outer switch 21 outside the vehicle while the vehicle is running. Therefore, in the present embodiment, if it is detected that the outer switch 21 is in the on state during traveling, it is determined that the outer switch 21 is fixed (that is, short-circuited).
　上記（ｉｉ）は、バックドア１０が閉まっている時には、インナースイッチ２２の配置からユーザーが操作することはできないので（具体的にはインナースイッチ２２は隠れてしまうので）インナースイッチ２２がオン状態となるはずはない、といった着想に基づく。よって、本実施の形態では、バックドア１０が閉まっている時にインナースイッチ２２がオン状態であることが検出されれば、インナースイッチ２２は固着（つまりショート）していると判断する。 In the above (ii), when the back door 10 is closed, the user cannot operate from the arrangement of the inner switch 22 (specifically, since the inner switch 22 is hidden), the inner switch 22 is turned on. It is based on the idea that it cannot be. Therefore, in the present embodiment, if it is detected that the inner switch 22 is on when the back door 10 is closed, it is determined that the inner switch 22 is fixed (that is, short-circuited).
　図２は、本実施の形態のゲート開閉装置の要部構成を示すブロック図である。ゲート開閉装置１００は、車両の運転者など（以下、「ユーザー」と称する）によってアウタースイッチ２１、インナースイッチ２２の操作が行われた場合に、電動モーターを駆動源としてバックドア１０（図１）などの開閉部材１０１を自動的に開閉する。本実施の形態では、ゲート開閉装置１００は、ミニバンやＳＵＶ（Sport Utility Vehicle）等の車両に搭載される。 FIG. 2 is a block diagram showing a main configuration of the gate opening / closing device of the present embodiment. The gate opening / closing device 100 uses the electric motor as a drive source when the outer switch 21 and the inner switch 22 are operated by a vehicle driver or the like (hereinafter, referred to as a “user”) (FIG. 1). The opening and closing member 101 is automatically opened and closed. In the present embodiment, the gate opening / closing device 100 is mounted on a vehicle such as a minivan or an SUV (Sport Utility Vehicle).
　ゲート開閉装置１００は、アウタースイッチ２１、インナースイッチ２２、開閉部材１０１、制御部１０２、駆動部１０３、警告部１０４、車速センサー１０５及び開閉センサー１０６を有する。なお、制御部１０２は、故障検知部、駆動制御部及び警告制御部としての機能を有する。 The gate opening / closing device 100 includes an outer switch 21, an inner switch 22, an opening / closing member 101, a control unit 102, a driving unit 103, a warning unit 104, a vehicle speed sensor 105, and an opening / closing sensor 106. Note that the control unit 102 has functions as a failure detection unit, a drive control unit, and a warning control unit.
　図１で説明したように、アウタースイッチ２１はユーザーによって操作される部分が車両の外面に設けられている。また、インナースイッチ２２はユーザーによって操作される部分が、開閉部材１０１（バックドア１０）が閉じられた状態において、ユーザーから隠れる位置、換言すればユーザーが操作できない位置に設けられている。 As described with reference to FIG. 1, the outer switch 21 has a portion operated by the user provided on the outer surface of the vehicle. Further, the portion of the inner switch 22 operated by the user is provided at a position where the inner switch 22 is hidden from the user when the opening / closing member 101 (back door 10) is closed, in other words, at a position where the user cannot operate.
　開閉部材１０１は、バックドア１０、スライドドアなどの車両に設けられた開口部を開閉可能な部材である。 The opening / closing member 101 is a member that can open and close an opening provided in the vehicle, such as the back door 10 and the sliding door.
　制御部１０２は、図示しないが、例えば、ＣＰＵ（Central Processing Unit）、制御プログラムを格納したＲＯＭ（Read Only Memory）などの記憶媒体、及びＲＡＭ（Random Access Memory）などの作業用メモリを有し、ＣＰＵが制御プログラムを実行することにより、故障検知、駆動制御及び警告制御の各機能を実現する。 Although not shown, the control unit 102 includes, for example, a CPU (Central Processing Unit), a storage medium such as a ROM (Read Only Memory) storing a control program, and a working memory such as a RAM (Random Access Memory). The CPU executes the control program to realize the functions of failure detection, drive control, and warning control.
　駆動部１０３は、電動モーターなどにより具現化されており、開閉部材１０１（本実施の形態の場合、バックドア１０）を開閉駆動する。 The driving unit 103 is embodied by an electric motor or the like, and drives the opening / closing member 101 (the back door 10 in the present embodiment) to open and close.
　警告部１０４は、アウタースイッチ２１及びインナースイッチ２２の故障が検知されたときに、ゲート開閉装置１００が使用できないことを示す警告を出力する。警告部１０４は、例えばメーター表示部などにより具現化されており、アウタースイッチ２１及びインナースイッチ２２の故障が検知されたときにメーター表示部にゲート開閉装置１００が使用できないことを示すシステムエラーを表示する。 The warning unit 104 outputs a warning indicating that the gate opening / closing device 100 cannot be used when the failure of the outer switch 21 and the inner switch 22 is detected.

I do.
　開閉センサー１０６は、開閉部材１０１が開状態か閉状態かを検知するセンサーである。開閉センサー１０６は、本実施の形態の場合には例えばバックドア１０の係合爪（図示せず）が係合する車体本体側のロック機構に設けられており、バックドア１０の係合爪が車体本体側のロック機構に係合したときに開閉部材１０１（バックドア１０）が閉状態であり、それ以外のときは開状態であることを検知する。 The open / close sensor 106 is a sensor that detects whether the open / close member 101 is open or closed. In the case of the present embodiment, the opening / closing sensor 106 is provided, for example, in a lock mechanism on the vehicle body main body with which an engaging claw (not shown) of the back door 10 is engaged. It detects that the opening / closing member 101 (back door 10) is in the closed state when engaged with the locking mechanism on the vehicle body side, and that it is in the open state otherwise.
　次に、図３及び図４を用いて、本実施の形態のゲート開閉装置１００の動作について説明する。図３はアウタースイッチ２１がオン操作されたときのゲート開閉装置１００の動作を示すフローチャートであり、図４はインナースイッチ２２がオン操作されたときのゲート開閉装置１００の動作を示すフローチャートである。 Next, the operation of the gate opening / closing device 100 according to the present embodiment will be described with reference to FIGS. FIG. 3 is a flowchart showing the operation of the gate opening / closing device 100 when the outer switch 21 is turned on, and FIG. 4 is a flowchart showing the operation of the gate opening / closing device 100 when the inner switch 22 is turned on.
　図３に示したように、ゲート開閉装置１００の制御部１０２は、ステップＳ１０においてアウタースイッチ２１がオンされるとステップＳ１１に移る。ステップＳ１１において、制御部１０２は、車速センサー１０５からの入力に基づいて、車速が０ｋｍ／ｈより大きいか否かを判断する。制御部１０２は、車速が０ｋｍ／ｈより大きいと判断すると、ステップＳ１２に移って、アウタースイッチ２１が故障している（つまり固着している）と判断するとともに故障していることを記憶し、続くステップＳ１３において警告部１０４に故障表示を行わせる。つまり、制御部１０２は、車速が０ｋｍ／ｈでないにもかかわらずアウタースイッチ２１がオン状態である場合に、アウタースイッチ２１が故障している（つまり固着している）と判断する。一方、制御部１０２は、ステップＳ１１において否定結果を得た場合（つまり車速が０ｋｍ／ｈである結果を得た場合）、ステップＳ１４に移る。制御部１０２は、ステップＳ１４においてアウタースイッチ２１の故障が記憶されていないと判断した場合には、ステップＳ１５に移って駆動部１０３を制御することにより開閉部材１０１（バックドア１０）を開駆動する。 制 御 As shown in FIG. 3, when the outer switch 21 is turned on in step S10, the control unit 102 of the gate opening / closing device 100 proceeds to step S11. In step S11, the control unit 102 determines whether the vehicle speed is higher than 0 km / h based on the input from the vehicle speed sensor 105. When the control unit 102 determines that the vehicle speed is greater than 0 km / h, the control unit 102 proceeds to step S12, determines that the outer switch 21 is faulty (that is, is stuck), and stores that the outer switch 21 is faulty. In the following step S13, the warning unit 104 is caused to display a failure. That is, the control unit 102 determines that the outer switch 21 has failed (that is, is stuck) when the outer switch 21 is in the ON state despite the vehicle speed not being 0 km / h. On the other hand, if a negative result is obtained in step S11 (that is, a result in which the vehicle speed is 0 km / h), the control unit 102 proceeds to step S14. If the control unit 102 determines in step S14 that the failure of the outer switch 21 is not stored, the process proceeds to step S15 to control the driving unit 103 to open the opening / closing member 101 (the back door 10). .
　図４に示したように、ゲート開閉装置１００の制御部１０２は、ステップＳ２０においてインナースイッチ２２がオンされるとステップＳ２１に移る。ステップＳ２１において、制御部１０２は、開閉センサー１０６からの入力に基づいて、開閉部材１０１（バックドア１０）が閉状態であるか否かを判断する。制御部１０２は、開閉部材１０１（バックドア１０）が閉状態であると判断すると、ステップＳ２２に移って、インナースイッチ２２が故障している（つまり固着している）と判断するとともに故障していることを記憶し、続くステップＳ２３において警告部１０４に故障表示を行わせる。つまり、制御部１０２は、開閉部材１０１（バックドア１０）が閉状態にあるにもかかわらずインナースイッチ２２がオン状態である場合に、インナースイッチ２２が故障している（つまり固着している）と判断する。一方、制御部１０２は、ステップＳ２１において否定結果を得た場合（つまり開閉部材１０１（バックドア１０）が開状態である結果を得た場合）、ステップＳ２４に移る。制御部１０２は、ステップＳ２４においてインナースイッチ２１の故障が記憶されていないと判断した場合には、ステップＳ２５に移って駆動部１０３を制御することにより開閉部材１０１（バックドア１０）を閉駆動する。 4) As shown in FIG. 4, when the inner switch 22 is turned on in step S20, the control unit 102 of the gate opening / closing device 100 proceeds to step S21. In step S21, the control unit 102 determines whether the opening / closing member 101 (the back door 10) is in a closed state based on an input from the opening / closing sensor 106. When determining that the opening / closing member 101 (back door 10) is in the closed state, the control unit 102 proceeds to step S22, determines that the inner switch 22 is malfunctioning (that is, is stuck), and malfunctions. Is stored, and in step S23, the warning unit 104 displays a failure. That is, when the inner switch 22 is in the ON state even though the opening / closing member 101 (the back door 10) is in the closed state, the control unit 102 has failed (that is, is stuck). Judge. On the other hand, when a negative result is obtained in step S21 (that is, when the result that the opening / closing member 101 (the back door 10) is in the open state) is obtained, the control unit 102 proceeds to step S24. When the control unit 102 determines that the failure of the inner switch 21 is not stored in step S24, the process proceeds to step S25 to control the driving unit 103 to close the opening / closing member 101 (the back door 10). .
　以上説明したように、本実施の形態によれば、アウタースイッチ２１の状態と車速との関係に基づき、具体的には車速が０ｋｍ／ｈより大きくかつアウタースイッチ２１がオン状態のときに、アウタースイッチ２１が故障していると判断する。また、本実施の形態によれば、インナースイッチ２２の状態と開閉部材１０１の開閉状態との関係に基づき、具体的には開閉部材１０１（バックドア１０）が閉状態でかつインナースイッチ２２がオン状態のときに、インナースイッチ２２が故障していると判断する。 As described above, according to the present embodiment, based on the relationship between the state of the outer switch 21 and the vehicle speed, specifically, when the vehicle speed is greater than 0 km / h and the outer switch 21 is on, the outer It is determined that the switch 21 has failed. Further, according to the present embodiment, based on the relationship between the state of inner switch 22 and the open / closed state of open / close member 101, specifically, open / close member 101 (back door 10) is closed and inner switch 22 is turned on. In this state, it is determined that the inner switch 22 has failed.
　このようにすることで、タイマーを使わずに迅速にアウタースイッチ２１及びインナースイッチ２２の故障判断を行うことができる車両のゲート開閉装置１００を実現できる。 By doing so, it is possible to realize the gate opening / closing device 100 for a vehicle that can quickly determine the failure of the outer switch 21 and the inner switch 22 without using a timer.
　上述の実施の形態は、本発明を実施するにあたっての具体化の一例を示したものに過ぎず、これらによって本発明の技術的範囲が限定的に解釈されてはならないものである。すなわち、本発明はその要旨、またはその主要な特徴から逸脱することの無い範囲で、様々な形で実施することができる。 The above-described embodiments are merely examples of specific embodiments for carrying out the present invention, and the technical scope of the present invention should not be interpreted in a limited manner. That is, the present invention can be implemented in various forms without departing from the gist or the main features thereof.
　上述の実施の形態で説明した、アウタースイッチ２１の故障検知機能、及び、インナースイッチ２２の故障検知機能は、その両方を車両に搭載してもよく、いずれか一方のみを車両に搭載してもよい。 The failure detection function of the outer switch 21 and the failure detection function of the inner switch 22, which have been described in the above embodiment, may be mounted on the vehicle, or both may be mounted on the vehicle. Good.
　上述の実施の形態では、主に開閉部材１０１がバックドア１０であり、アウタースイッチ２１がバックドア１０の外面に設けられ、インナースイッチ２２がバックドア１０の下側に設けられた場合について説明したが、開閉部材１０１はバックドア１０に限らず、例えばスライドドアなどでもよい。アウタースイッチ２１は車両の外面側に設けられていればよく、インナースイッチ２２は開閉部材１０１が閉状態のときに隠れる位置（つまりユーザーが操作できない位置）に設けられていればよい。 In the above-described embodiment, a case has been described in which the opening / closing member 101 is mainly the back door 10, the outer switch 21 is provided on the outer surface of the back door 10, and the inner switch 22 is provided below the back door 10. However, the opening / closing member 101 is not limited to the back door 10 and may be, for example, a sliding door. The outer switch 21 may be provided on the outer surface side of the vehicle, and the inner switch 22 may be provided at a position that is hidden when the opening / closing member 101 is in the closed state (that is, a position where the user cannot operate).
　例えば、バスの車体の外面側には乗務員が車両の外側から乗降扉を開閉するためのアウター／インナースイッチが設けられている。このアウター／インナースイッチのアウタースイッチの故障検出に関しても上述したアウタースイッチの故障検出方法を適用できる。つまり、乗務員がアウタースイッチをオン操作するのは車速が０ｋｍ／ｈのときのみであることを考慮して、車速が０ｋｍ／ｈのとき以外にアウタースイッチがオン状態となっていればアウタースイッチが故障していると判断する。 For example, an outer / inner switch is provided on the outer surface side of the body of a bus so that a crew member can open and close a door from outside the vehicle. The outer switch failure detection method described above can be applied to the outer switch failure detection of the outer / inner switch. In other words, considering that the crew only turns on the outer switch when the vehicle speed is 0 km / h, if the outer switch is on other than when the vehicle speed is 0 km / h, the outer switch is turned on. Judge that it is out of order.
　さらに、上述の実施の形態では、車速が０ｋｍ／ｈより大きくかつアウタースイッチ２１がオン状態のときに、アウタースイッチ２１が故障していると判断する場合について述べたが、車速が所定値より大きくかつアウタースイッチ２１がオン状態のときにアウタースイッチ２１が故障していると判断するようにしてもよい。例えば、作業車などでは走行中のアウタースイッチ２１の操作を受け付けて走行中であっても開閉部材１０１を開駆動する場合もある。このような場合を想定して、アウタースイッチ２１の故障判断に用いる車速のしきい値を０ｋｍ／ｈではない値に設定してもよい。具体的には、ステップＳ１１（図４）において、車速が所定値（例えば６０ｋｍ／ｈ）より大きいか否かを判断すればよい。 Further, in the above-described embodiment, a case has been described where it is determined that the outer switch 21 is out of order when the vehicle speed is greater than 0 km / h and the outer switch 21 is in the ON state. In addition, when the outer switch 21 is in the ON state, it may be determined that the outer switch 21 is out of order. For example, in a work vehicle or the like, the opening / closing member 101 may be driven to open even when the vehicle is traveling while receiving an operation of the outer switch 21 during traveling. Assuming such a case, the threshold value of the vehicle speed used for the failure determination of the outer switch 21 may be set to a value other than 0 km / h. Specifically, in step S11 (FIG. 4), it may be determined whether the vehicle speed is higher than a predetermined value (for example, 60 km / h).
