Description

【0001】
【発明の属する技術分野】
本発明は、車両が水没したことを検出し、ウインドロックがされていても、助手席側窓ガラスを確実に開けることができる車両の水没対策装置に関する。
【0002】
【従来の技術】
近年、自動車等の車両においては、モータ等により窓ガラスを開閉するパワーウインド機構が一般的に搭載されている。このようなパワーウインド機構を搭載した車両の場合、不慮の事故などにより海や湖等に水没したときにそなえて、水没時には窓ガラスを自動的に開放したり、手動操作で確実に開放可能なようにすることにより、搭乗者が車外へ容易に脱出できるようにする水没対応手段を設けることが種々検討されている。
【0003】
このような水没対応手段としては、水没状態を検出する水没検出手段、動作制御を行う制御回路、窓ガラスを開閉駆動するモータ等に駆動電力を供給する駆動回路を有し、水没したことを検出して窓ガラスを強制的に開放したり、緊急時のバックアップ回路を動作させて窓ガラスを確実に開放可能にするような構成が用いられる。
【0004】
【発明が解決しようとする課題】
しかしながら、一般のパワーウインド機構には、ウインドロック機構が付いており、従来のウインドロック機構は、メカセル方式と云う機械的な制御方式を用いており、ウインドロックがオンになっていると、これを解除しない限り、助手席側の窓の開閉ができない、という問題点がある。
【0005】
本発明は、上記問題点を解消するためになされたもので、車両が水没したときに、運転席側でパワーウインド機構がロックされている場合でも、助手席側のスイッチ操作のみで、窓ガラスを開けることができる水没対策装置を提供することを目的としている。
【0006】
【課題を解決するための手段】
本発明による車両の水没対策装置は、例えば、パワーウインド機構に電気的に制御するローカレント方式を用い、車両における電子回路を搭載した基板に、水没バックアップ回路を有する車両の水没対策装置であって、
該水没バックアップ回路は、水没状態を検出するための水没検出手段と、前記水没検出手段の出力に基づいて水没時に運転席以外の窓のロックを解除するウインドロック解除手段とを有し、該水没バックアップ回路は水没時に窓の開き方向動作のみ可能に窓の駆動制御を行うように構成された車両の水没対策装置おいて、
前記水没バックアップ回路は、操作スイッチを開ける側に操作した場合に、窓を開けるように駆動し、操作スイッチを閉める側に操作した場合に、窓の駆動を行わないように駆動制御を行うように構成されたこと、を特徴とする(請求項1)。
【0007】
また、本発明による車両の水没対策装置は、例えば、パワーウインド機構に電気的に制御するローカレント方式を用い、車両における電子回路を搭載した基板に、水没バックアップ回路を有する車両の水没対策装置であって、
該水没バックアップ回路は、水没状態を検出するための水没検出手段と、前記水没検出手段の出力に基づいて水没時に運転席以外の窓のロックを解除するウインドロック解除手段とを有し、該水没バックアップ回路は水没時に窓の開き方向動作のみ可能に窓の駆動制御を行うように構成された車両の水没対策装置おいて、
少なくとも前記水没バックアップ回路の構成部材が耐水コーティングされたこと、を特徴とする(請求項2)。
尚、水没バックアップ回路が、助手席側に設置されることが好ましい(請求項3)。
上記構成により、車両が水没したときに、ウインドロック機構が解除されるとともに、パワーウインドがロック機構は操作スイッチの手動操作により下降方向のみに作動可能で上昇方向には作動しないようになるため、運転席側でパワーウインドがロックされている場合でも、助手席側のスイッチ操作のみで、確実に窓ガラスを開けることが可能となる。
【0008】
【発明の実施の形態】
以下、図面を参照して本発明の実施の形態を説明する。
図1は本発明の一実施形態に係る水没対策装置の構成を示す回路図である。
図2は本発明の一実施形態に係る水没対策装置の水没検知部の構成の一例を示す回路図である。
本実施の形態における水没対策装置1は、助手席側回路ブロック2、運転席側回路ブロック3より構成されている。
通常時は、助手席搭乗者が助手席側の操作スイッチASSW1を操作することによって、助手席の窓のウインドガラス17を開閉する。
【0009】
また、運転席搭乗者が助手席遠隔操作スイッチASSW2を運転席にて操作し、制御信号UPSIG、DOWNSIGを送ることにより、助手席のウインドガラス17を開閉させることもでき、さらに、ウインドロックスイッチWLSWを操作して、ロック用スイッチ回路21からウインドロック信号WLSIGを送ることにより、助手席搭乗者が助手席側の操作スイッチASSW1を操作しても助手席のウインドガラス17が開閉できないようにロックすることもできる。
【0010】
車両が水没した時に上記のように、助手席のウインドガラス17が開閉できないようにロックされている場合、助手席搭乗者が助手席側の操作スイッチASSW1を操作して、助手席のウインドガラス17を開けられるように、助手席側回路ブロック2が構成されており、以下、助手席側回路ブロック2について詳細に説明する。
【0011】
助手席側回路ブロック2は、水没時に動作する水没バックアップ回路10を有するものであり、他には、UP側スイッチ回路13、DOWN側スイッチ回路14、切り替えリレーRLY1、助手席側の操作スイッチASSW1、その他の回路素子を有して構成されている。
【0012】
水没バックアップ回路10は水没状態を検知するための水没検出手段に該当する水没検知部11、制御回路IC1、コンデンサC1、抵抗R6,R7,R8,R9,R14、ダイオードD3、コンデンサC1、ウインドロック解除手段に該当するロック解除用スイッチ回路15を有して構成されている。
【0013】
水没検知部11は、水没状態を検知するための水没検知手段WS1と、水没状態が検知されたときに水没検出信号を出力する検出信号出力回路T1と、が設けられている。水没検知手段WS1は、例えば、図2に示すような構成を用いることができる。
【0014】
これは、車両の水没時に2つの半田パッド間の長穴22を介して導通状態となる構成であり、第1の半田パッド21がグランドに第2の半田パッド23が検出信号出力回路T1にそれぞれ接続されている。検出信号出力回路T1は、トランジスタと抵抗を有して構成されており、トランジスタのベースが水没検知手段WS1の第2の半田パッド23と接続され、エミッタには制御系電源電圧VLが供給され、コレクタは抵抗R14を介してロック解除用スイッチ回路15の制御入力端に、また、ダイオードD3を介して抵抗R6,R7に接続され、さらに、抵抗R6からはUP側スイッチ回路13の制御入力端に、抵抗R7からはDOWN側スイッチ回路14の制御入力端にそれぞれ接続されている。ロック解除スイッチ回路15は、UP側スイッチ回路13及びDOWN側スイッチ回路14の一端とグランドとの接続状態を切り替え、グランドと接続することによってウインドロックを解除する構成になっている。
【0015】
また、助手席側の操作スイッチASSW1は、上昇回転の際にはUPへ、下降回転の際にはDOWNに接続されるように構成されている。そして、トランジスタTR5のベースが抵抗R11を介してUPと接続され、エミッタには抵抗R3を介してバッテリ電源電圧VBが供給され、コレクタはダイオードD1及び抵抗R4を介してUP側スイッチ回路13の制御入力端に接続されている。一方、トランジスタTR6のベースが抵抗R13を介してDOWNと接続され、エミッタには抵抗R3を介してバッテリ電源電圧VBが供給され、コレクタはダイオードD2及び抵抗R5を介してDOWN側スイッチ回路14の制御入力端に接続されている。
【0016】
さらに、これらUP側スイッチ回路13,DOWN側スイッチ回路14の他端は、切り替えリレーRLY1のコイルL1,L2と接続され、この切り替えリレーRLY1のリレースイッチはパワーウインドの駆動用モータ16に接続されている。そして、切り替えリレーRLY1を介して、駆動用モータ16にバッテリ電源電圧VBを供給し、駆動用モータ16を回転させることにより、ウインドガラス17が上昇又は下降して開閉するように構成されている。
【0017】
制御回路IC1は、その入力端子の一方が助手席側の操作スイッチASSW1のDOWNに接続されており、他方は、制御系電源電圧VLを抵抗R8,R9の間で分圧した所定電圧が供給され、コンデンサC1が両方の入力端子間に挿入されている。そして、制御回路IC1は、その出力端子が、UP側スイッチ回路13の制御入力端に接続されており、操作スイッチASSW1のDOWN操作を検出してUP側スイッチ回路13を制御するようになっている。
【0018】
次に、上記のように構成された水没対策装置の動作について説明する。
車両が水没したときには、車内に淡水や塩水などの水が浸入していって水没検知手段WS1が浸水する。そして、浸入した水によって水没検知手段WS1の長穴22が塞がれ、半田パッド21,22の間にリーク電流が流れて導通状態となる。これにより、検出信号出力回路T1のトランジスタのベース電位が接地レベルに近いローレベルとなり、トランジスタがオンする。これにより、検出信号出力回路T1のトランジスタのオン電流が水没検出信号としてUP側スイッチ回路13,DOWN側スイッチ回路14,ロック解除用スイッチ回路15に送出される。
【0019】
これにより、UP側スイッチ回路13,DOWN側スイッチ回路14,ロック解除用スイッチ回路15がオン状態になるため、運転席側回路ブロック3のロック用スイッチ手段21がオンされている場合でも、ウインドロック信号WLSIGがロー状態になり、ウインドロックが解除される。このように、WLSIGがロー状態になることにより、切り替えリレーRLY1のUP側のコイルL1及びDOWN側のコイルL2に電流が流れ、両方のリレースイッチがバッテリ電源電圧VB側に接続される(オン状態)。この状態のとき、搭乗者により、助手席側の操作スイッチASSW1がDOWN側に接続されると、BDがローレベルとなる。制御回路IC1は、入力がローレベルになると、UP側スイッチ回路13をオフさせる。
【0020】
これにより、切り替えリレーRLY1のUP側のコイルL1に電流が流れなくなり、UP側が接地され(オフ状態)、DOWN側のリレースイッチのみがオン状態となることにより、駆動用モータ16に駆動電流が流れて下降回転(DOWN)し、ウインドガラス17が下降するので、助手席側の窓が開く。
【0021】
また、助手席側の操作スイッチASSW1がUP側に接続されるか、あるいは、UP,DOWNのどちらにも接続されない状態では、BDがハイレベルとなる。水没バックアップ回路10内の制御回路IC1は、入力がハイレベルになると、UP側スイッチ回路13をオンさせる。これにより、切り替えリレーRLY1のUP側のコイルL1に電流が流れ、UP側のリレースイッチがオン状態になり、駆動用モータ16には駆動電流が流れずに回転停止状態となる。このため、搭乗者がUP動作を行ってもパワーウインド機構は作動せず、窓が閉まることはない。
【0022】
なお、上記水没対策装置において、特定の部材、例えば水没時に作動する必要のある水没バックアップ回路10、UP側スイッチ回路13、DOWN側スイッチ回路14、切り替えリレーRLY1などの回路構成部材には、耐水コーティングを施してもよい。
【0023】
また、運転席側に水没検知部を助手席側と同様に設けて、運転席側で水没状態を検出してウインドロックを解除するように構成することも可能である。
【0024】
【発明の効果】
本発明による車両の水没対策装置によれば、車両における電子回路を搭載した基板に、水没バックアップ回路を有する車両の水没対策装置であって、該水没バックアップ回路は、水没状態を検出するための水没検出手段と、前記水没検出手段の出力に基づいて水没時に運転席以外の窓のロックを解除するウインドロック解除手段とを有し、該水没バックアップ回路は水没時に窓の開き方向動作のみ可能に窓の駆動制御を行うように構成された車両の水没対策装置おいて、前記水没バックアップ回路は、操作スイッチを開ける側に操作した場合に、窓を開けるように駆動し、操作スイッチを閉める側に操作した場合に、窓の駆動を行わないように駆動制御を行うように構成され、また、車両における電子回路を搭載した基板に、水没バックアップ回路を有する車両の水没対策装置であって、該水没バックアップ回路は、水没状態を検出するための水没検出手段と、前記水没検出手段の出力に基づいて水没時に運転席以外の窓のロックを解除するウインドロック解除手段とを有し、該水没バックアップ回路は水没時に窓の開き方向動作のみ可能に窓の駆動制御を行うように構成された車両の水没対策装置おいて、少なくとも前記水没バックアップ回路の構成部材が耐水コーティングされたことにより、水没時により確実に水没バックアップ回路を作動させ、窓ガラスの駆動制御を行うことができる。さらに、バックアップ回路が、助手席側に設置されたことにより、車両が水没したときに、運転席側でパワーウインドがロックされている場合でも、助手席側のスイッチ操作のみで、確実に窓ガラスを開けることができ、搭乗者が車外へ容易に脱出できるようにする車両の水没対策装置を提供できるものである。

It has a lock release switch circuit 15 corresponding to the means.
[0013]
The submergence detecting unit 11 is provided with submergence detecting means WS1 for detecting a submerged state, and a detection signal output circuit T1 for outputting a submerged detection signal when the submerged state is detected. The water immersion detecting means WS1 can use, for example, a configuration as shown in FIG.
[0014]
In this configuration, when the vehicle is submerged, the conductive state is established via the elongated hole 22 between the two solder pads. The first solder pad 21 is connected to the ground and the second solder pad 23 is connected to the detection signal output circuit T1. It is connected. The detection signal output circuit T1 includes a transistor and a resistor. The base of the transistor is connected to the second solder pad 23 of the submergence detecting means WS1, and the control system power supply voltage VL is supplied to the emitter. The collector is connected to the control input terminal of the unlocking switch circuit 15 via the resistor R14, to the resistors R6 and R7 via the diode D3, and from the resistor R6 to the control input terminal of the UP-side switch circuit 13. , And the resistor R7 are connected to control input terminals of the DOWN-side switch circuit 14, respectively.

In addition, the operation switch ASSW1 on the passenger seat side is configured to be connected to UP during upward rotation and to DOWN during downward rotation. The base of the transistor TR5 is connected to the UP via the resistor R11, the emitter is supplied with the battery power supply voltage VB via the resistor R3, and the collector is the control of the UP-side switch circuit 13 via the diode D1 and the resistor R4.

One of the input terminals of the control circuit IC1 is connected to the DOWN of the operation switch ASSW1 on the passenger seat side, and the other is supplied with a predetermined voltage obtained by dividing the control system power supply voltage VL between the resistors R8 and R9. , A capacitor C1 is inserted between both input terminals. The output terminal of the control circuit IC1 is connected to the control input terminal of the UP switch circuit 13, and detects the DOWN operation of the operation switch ASSW1 to control the UP switch circuit 13. .
[0018]
Next, the operation of the submergence countermeasure device configured as described above will be described.

Then, the elongated hole 22 of the submergence detecting means WS1 is closed by the intruded water, and a leak current flows between the solder pads 21 and 22 to be in a conductive state. As a result, the base potential of the transistor of the detection signal output circuit T1 becomes a low level close to the ground level, and the transistor is turned on. As a result, the ON current of the transistor of the detection signal output circuit T1 is sent to the UP switch circuit 13, the DOWN switch circuit 14, and the unlock switch circuit 15 as a submergence detection signal.
[0019]
As a result, the UP-side switch circuit 13, the DOWN-side switch circuit 14, and the unlocking switch circuit 15 are turned on. Therefore, even when the locking switch means 21 of the driver-side circuit block 3 is turned on, the window lock is provided. The signal WLSIG becomes low, and the window lock is released. As described above, when WLSIG is set to the low state, a current flows through the coil L1 on the UP side and the coil L2 on the DOWN side of the switching relay RLY1, and both relay switches are connected to the battery power supply voltage VB side (on state). ). In this state, when the passenger switches the operation switch ASSW1 on the passenger seat side to the DOWN side, the BD goes low. When the input goes low, the control circuit IC1 turns off the UP-side switch circuit 13.
[0020]
As a result, no current flows to the coil L1 on the UP side of the switching relay RLY1, the UP side is grounded (OFF state), and only the DOWN side relay switch is turned ON, so that the drive current flows to the drive motor 16. As the window glass 17 descends, the window on the passenger seat side opens.
[0021]
Further, when the operation switch ASSW1 on the passenger seat side is connected to the UP side or is not connected to either the UP or the DOWN, the BD is at the high level. The control circuit IC1 in the submerged backup circuit 10 turns on the UP-side switch circuit 13 when the input goes high. As a result, a current flows through the UP-side coil L1 of the switching relay RLY1, the UP-side relay switch is turned on, and the drive motor 16 is in a rotation stopped state without a drive current flowing. For this reason, even if the passenger performs the UP operation, the power window mechanism does not operate, and the window does not close.
[0022]
In the above-described submergence countermeasure device, specific components, for example, submerged backup circuit 10, UP side switch circuit 13, DOWN side switch circuit 14, which are required to operate when submerged, and circuit components such as switching relay RLY1 are coated with water resistant coating. May be applied.
[0023]
It is also possible to provide a submergence detection unit on the driver's seat side in the same way as the passenger's seat side so that the driver's seat side detects the submergence state and releases the wind lock.
