Description

本発明は、開閉部材制御装置に関するものである。 The present invention relates to an opening / closing member control device.

従来、開閉部材制御装置の１つであるパワーウィンドウ制御装置としては、ウィンドウガラスの閉動作時にモータの回転速度を常時監視し、回転速度の変化に基づいて挟み込みを検出し、挟み込みを検出すると挟み込まれた状態の異物を開放すべくモータを反転させるものがある（例えば、特許文献１参照）。このようなパワーウィンドウ制御装置では、ウィンドウガラスの閉動作時に挟み込まれた状態の異物を自動的に開放することができる。 Conventionally, as a power window control device, which is one of the opening / closing member control devices, the rotation speed of the motor is constantly monitored when the window glass is closed, pinching is detected based on the change in the rotation speed, and pinching is detected when the pinching is detected. There is a motor that reverses the motor in order to release the foreign matter in the state of being squeezed (see, for example, Patent Document 1). In such a power window control device, foreign matter in a pinched state can be automatically released when the window glass is closed.

特開２００９－２２８２８０号公報Japanese Unexamined Patent Publication No. 2009-228280

しかしながら、上記のようなパワーウィンドウ制御装置では、挟み込みを検出すると単にモータを反転させるだけであるため、挟み込みが検出されてから挟み込み荷重が無くなるまでの時間、すなわち開放されるまでの時間が、一般的に挟み込み荷重が掛かり始めてから挟み込みが検出されるまでの時間とほぼ同じ時間となり、遅いという問題がある。 However, in the power window control device as described above, when the pinch is detected, the motor is simply inverted. Therefore, the time from the detection of the pinch to the elimination of the pinch load, that is, the time until the pinch is released is generally used. There is a problem that the time is almost the same as the time from the start of the pinching load to the detection of the pinching, which is slow.

本発明は上記問題点を解消するためになされたものであって、その目的は、挟み込まれた状態の異物を早く開放することができる開閉部材制御装置を提供することにある。 The present invention has been made to solve the above problems, and an object of the present invention is to provide an opening / closing member control device capable of quickly releasing a foreign matter in a pinched state.

上記課題を解決する開閉部材制御装置は、開閉部材（１）を開閉させるためのモータ（Ｍ）と、前記開閉部材の閉動作時に異物の挟み込みを検出すると前記モータを反転させる制御部（４）とを備えた開閉部材制御装置であって、前記制御部は、前記開閉部材の閉動作時に異物の挟み込みを検出すると閉動作時の回転速度よりも速い回転速度で前記モータを反転させる高速反転制御を行うものであって、前記制御部は、前記高速反転制御の後、該高速反転制御よりも遅い回転速度で前記モータを反転させる低速反転制御を行う。 The opening / closing member control device that solves the above problems includes a motor (M) for opening / closing the opening / closing member (1), and a control unit (4) that reverses the motor when it detects that a foreign object is caught during the closing operation of the opening / closing member. An opening / closing member control device comprising the above, wherein the control unit reverses the motor at a rotation speed faster than the rotation speed at the closing operation when a foreign object is detected during the closing operation of the opening / closing member. After the high-speed reversal control, the control unit performs a low-speed reversal control for reversing the motor at a rotation speed slower than the high-speed reversal control .

同構成によれば、制御部は、開閉部材の閉動作時に異物の挟み込みを検出すると閉動作時の回転速度よりも速い回転速度で前記モータを反転させる高速反転制御を行うため、挟み込まれた状態の異物を早く開放することができる。 According to the same configuration, when the control unit detects that a foreign substance is caught during the closing operation of the opening / closing member, the control unit performs high-speed reversal control to reverse the motor at a rotation speed faster than the rotation speed at the closing operation. Foreign matter can be released quickly.

(B) is a time-rotational speed characteristic diagram in one embodiment.

以下、パワーウィンドウ制御装置の一実施形態を図１及び図２に従って説明する。
図１に示すように、車両ドアに設けられる開閉部材としてのウィンドウガラス１には図示しないレギュレータ等を介してパワーウィンドウ制御装置２のモータＭが駆動連結されている。モータＭは、直流モータであって、正転することでウィンドウガラス１を閉動作させ、反転することでウィンドウガラス１を開動作させる。 Hereinafter, an embodiment of the power window control device will be described with reference to FIGS. 1 and 2.
As shown in FIG. 1, a motor M of a power window control device 2 is driven and connected to a window glass 1 as an opening / closing member provided on a vehicle door via a regulator or the like (not shown). The motor M is a DC motor, and the window glass 1 is closed by rotating forward and the window glass 1 is opened by reversing.

パワーウィンドウ制御装置２は、モータＭの回転を検出するホールＩＣ等の回転検出センサ３を備える。また、パワーウィンドウ制御装置２は、図示しない操作スイッチからの信号や前記回転検出センサ３からの信号等に基づいてモータＭを制御する制御部４を備えている。 The power window control device 2 includes a rotation detection sensor 3 such as a Hall IC that detects the rotation of the motor M. Further, the power window control device 2 includes a control unit 4 that controls the motor M based on a signal from an operation switch (not shown), a signal from the rotation detection sensor 3, and the like.

制御部４は、マイコンや駆動回路等からなる。制御部４は、駆動回路のデューティ比を変更することでモータＭの駆動電圧を変更するＰＷＭ制御によってモータＭの回転速度を調節可能とされている。制御部４は、モータＭの正転時であってウィンドウガラス１の閉動作時に異物の挟み込みを検出可能とされている。本実施形態の制御部４は、ウィンドウガラス１の閉動作時に回転検出センサ３からの信号によってモータＭの回転速度を監視し、その回転速度が挟み込み閾値Ｈまで低下すると異物が挟み込まれたと判定する。なお、挟み込み閾値Ｈは、ウィンドウガラス１の位置毎に応じて予め学習されて記憶されたデータである。そして、制御部４は、異物の挟み込みを検出するとモータＭを反転させてウィンドウガラス１を開動作させる。 The control unit 4 includes a microcomputer, a drive circuit, and the like. The control unit 4 is capable of adjusting the rotation speed of the motor M by PWM control that changes the drive voltage of the motor M by changing the duty ratio of the drive circuit. The control unit 4 is capable of detecting the pinching of foreign matter during the normal rotation of the motor M and the closing operation of the window glass 1. The control unit 4 of the present embodiment monitors the rotation speed of the motor M by a signal from the rotation detection sensor 3 when the window glass 1 is closed, and determines that foreign matter is pinched when the rotation speed drops to the pinching threshold H. .. The sandwiching threshold value H is data that has been learned and stored in advance according to each position of the window glass 1. Then, when the control unit 4 detects that the foreign matter is caught, the control unit 4 inverts the motor M to open the window glass 1.

ここで、本実施形態の制御部４は、ウィンドウガラス１の閉動作時に異物の挟み込みを検出すると閉動作時の回転速度よりも速い回転速度でモータＭを反転させる高速反転制御を行う。また、制御部４は、前記高速反転制御の後、該高速反転制御よりも遅い回転速度でモータＭを反転させる低速反転制御を行う。前記低速反転制御でのモータＭの回転速度は、挟み込みを検出する直前の閉動作時のモータＭの回転速度と同じに設定されている。また、制御部４は、前記低速反転制御を、挟み込み荷重が無くなるタイミングで開始する。そして、制御部４は、異物の挟み込みを検出すると予め設定された量だけモータＭを反転させてからモータＭを停止させる。 Here, the control unit 4 of the present embodiment performs high-speed reversal control in which the motor M is reversed at a rotation speed higher than the rotation speed at the time of the closing operation when the pinching of foreign matter is detected during the closing operation of the window glass 1. Further, the control unit 4 performs low-speed reversal control for reversing the motor M at a rotation speed slower than the high-speed reversal control after the high-speed reversal control. The rotation speed of the motor M in the low-speed reversal control is set to be the same as the rotation speed of the motor M at the time of closing operation immediately before detecting pinching. Further, the control unit 4 starts the low-speed reversal control at the timing when the sandwiching load disappears. Then, when the control unit 4 detects that the foreign matter is caught, the control unit 4 inverts the motor M by a preset amount and then stops the motor M.

次に、上記のように構成されたパワーウィンドウ制御装置２の動作及び作用について詳述する。
例えば、図２（ａ）及び図２（ｂ）に示すように、ウィンドウガラス１の閉動作時のタイミングＴ１で異物の挟み込みが開始されると、挟み込み荷重Ｘが徐々に増加するとともにモータＭの回転速度Ｓが低下する。そして、タイミングＴ２で回転速度Ｓが挟み込み閾値Ｈまで低下すると制御部４にて異物が挟み込まれたと判定される。すると、制御部４によって閉動作時のモータＭの回転速度Ｓ１よりも速い回転速度Ｓ２でモータＭを反転させる高速反転制御が行われる。すなわち、高速反転制御では、制御部４によって閉動作時よりも駆動回路のデューティ比が上げられて駆動電圧が大きくされつつモータＭが反転されて開動作が行われる。これにより、挟み込み荷重Ｘが急激に低減される。そして、挟み込み荷重Ｘが無くなる、すなわち挟み込まれた状態の異物が開放されるタイミングＴ３で制御部４によって前記高速反転制御よりも遅い回転速度でモータＭを反転させる低速反転制御が行われる。なお、挟み込み荷重Ｘが無くなるタイミングＴ３は、例えば回転速度Ｓが低下を開始して挟み込みが始まったタイミングＴ１から挟み込み荷重Ｘが挟み込み閾値Ｈまで低下したタイミングＴ２までの回転数分だけモータＭが反転したことで判定される。そして、低速反転制御では、モータＭの回転速度は、挟み込みを検出する直前の閉動作時のモータＭの回転速度Ｓ１と同じとされるべく低下される。そして、予め設定された量だけモータＭが反転されると制御部４によってモータＭは停止される。 Next, the operation and operation of the power window control device 2 configured as described above will be described in detail.
For example, as shown in FIGS. 2A and 2B, when the pinching of foreign matter is started at the timing T1 when the window glass 1 is closed, the pinching load X gradually increases and the motor M The rotation speed S decreases. Then, when the rotation speed S drops to the pinching threshold value H at the timing T2, the control unit 4 determines that the foreign matter is pinched. Then, the control unit 4 performs high-speed reversal control for reversing the motor M at a rotation speed S2 faster than the rotation speed S1 of the motor M during the closed operation. That is, in the high-speed inversion control, the duty ratio of the drive circuit is raised by the control unit 4 as compared with the closed operation, the drive voltage is increased, and the motor M is inverted to perform the open operation. As a result, the sandwiching load X is sharply reduced. Then, at the timing T3 when the pinching load X disappears, that is, the foreign matter in the pinched state is released, the control unit 4 performs low-speed reversal control for reversing the motor M at a rotation speed slower than the high-speed reversal control. At the timing T3 when the pinching load X disappears, for example, the motor M reverses by the number of rotations from the timing T1 when the rotation speed S starts to decrease to the timing T2 when the pinching load X drops to the pinching threshold value H. It is judged by doing. Then, in the low-speed reversal control, the rotation speed of the motor M is lowered so as to be the same as the rotation speed S1 of the motor M at the time of the closing operation immediately before detecting the pinching. Then, when the motor M is inverted by a preset amount, the motor M is stopped by the control unit 4.

次に、上記実施形態の効果を以下に記載する。
（１）制御部４は、ウィンドウガラス１の閉動作時に異物の挟み込みを検出すると閉動作時の回転速度Ｓ１よりも速い回転速度Ｓ２でモータＭを反転させる高速反転制御を行うため、挟み込まれた状態の異物を早く開放することができる。すなわち、挟み込みを検出した際に閉動作時の回転速度Ｓ１と同様の回転速度でモータＭを反転させる制御では、図２（ａ）に破線で示すように、挟み込み荷重Ｘｚの低減が緩やかとなるが、本実施形態では挟み込み荷重Ｘが急激に低減され、挟み込まれた状態の異物を早く開放することができる。 Next, the effects of the above embodiment will be described below.
(1) The control unit 4 is sandwiched in order to perform high-speed reversal control for reversing the motor M at a rotation speed S2 faster than the rotation speed S1 at the time of closing operation when the pinching of foreign matter is detected during the closing operation of the window glass 1. Foreign matter in the state can be released quickly. That is, in the control of reversing the motor M at the same rotation speed as the rotation speed S1 at the time of closing operation when the pinching is detected, the pinching load Xz is gradually reduced as shown by the broken line in FIG. 2 (a). However, in the present embodiment, the pinching load X is sharply reduced, and the pinched foreign matter can be quickly released.

（２）制御部４は、前記高速反転制御の後、該高速反転制御よりも遅い回転速度でモータＭを反転させる低速反転制御を行うため、最も挟み込まれた状態から早く挟み込み荷重を低減させることができるとともに速度変化による高級感を演出することができる。 (2) Since the control unit 4 performs low-speed reversal control for reversing the motor M at a rotation speed slower than the high-speed reversal control after the high-speed reversal control, the pinching load can be reduced quickly from the most pinched state. At the same time, it is possible to produce a sense of luxury by changing the speed.

（３）前記低速反転制御でのモータＭの回転速度は、挟み込みを検出する直前の閉動作時のモータＭの回転速度Ｓ１と同じに設定されるため、ウィンドウガラス１が多数の速度で動作する場合に比べて違和感が少なくなる。 (3) Since the rotation speed of the motor M in the low-speed reversal control is set to be the same as the rotation speed S1 of the motor M at the time of closing operation immediately before detecting pinching, the window glass 1 operates at a large number of speeds. There is less discomfort than in the case.

（４）制御部４は、前記低速反転制御を、挟み込み荷重が無くなるタイミングＴ３で開始するため、挟み込まれた状態の異物を早く開放することができ、開放されたタイミングＴ３で低速反転制御により高級感を演出することができる。 (4) Since the control unit 4 starts the low-speed reversal control at the timing T3 when the pinching load disappears, the foreign matter in the pinched state can be released quickly, and the high-grade by the low-speed reversal control at the released timing T3. You can produce a feeling.

（５）制御部４は、ウィンドウガラス１の閉動作時に異物の挟み込みを検出すると予め設定された量だけモータＭを反転させてからモータＭを停止させるため、ウィンドウガラス１の開度が必要以上に大きくなってしまうことがない。 (5) When the control unit 4 detects that a foreign substance is caught during the closing operation of the window glass 1, the control unit 4 inverts the motor M by a preset amount and then stops the motor M. Therefore, the opening degree of the window glass 1 is larger than necessary. It doesn't grow big.
