Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power window device, and more particularly to a power window device, comprising a manual switch and an auto switch for opening and closing the window, and moving the window in one direction by operating the auto switch. The present invention relates to a power window device capable of stopping movement of a window or moving the window in the other direction by operating a manual switch to be moved.

[0002]

2. Description of the Related Art Recently, in many automobiles, a power window device that can open and close an electric window by operating a window opening / closing switch when opening / closing a door window is used.

[0003] This power window device usually has a switch section having a manual switch for closing and opening directions and an automatic switch for closing and opening directions, and a manual switch for closing and opening directions or an automatic switch for closing and opening directions. A control unit that outputs a drive signal corresponding to the operation, a motor drive unit that outputs a motor rotation switching signal in response to the drive signal output by the control unit, and a window that is driven by the motor rotation switching signal. It has a relay control unit for switching the polarity of the power supplied to the opening and closing motor, and a window opening and closing motor for opening and closing the window by rotating.

[0004] In the power window device having the above configuration, when a passenger (driver or the like) of an automobile operates one of the manual switches of the switch unit, for example, the opening direction manual switch, the operation state is transmitted to the control unit. A drive signal corresponding to the operation of the opening direction manual switch is output from the control unit, and the drive signal is supplied to the motor drive unit. The motor driving unit outputs a motor rotation switching signal in response to the driving signal, and the motor rotation switching signal is supplied to the relay control unit. The relay control unit switches the polarity of power supplied to the window opening / closing motor in response to the motor rotation switching signal, and rotates the window opening / closing motor in one direction so as to move the window in the opening direction. In this case, when the operation of the opening direction manual switch is stopped, the stop of the operation is transmitted to the control unit, whereby the control unit controls the motor drive unit and the relay control unit so as to stop the rotation of the window opening / closing motor. By controlling, the movement of the window in the opening direction is stopped.

Similarly, when the closing direction manual switch of the switch section is operated, the window opening / closing motor rotates in the other direction to move the window in the closing direction by the same operation. Then, when the operation of the closing direction manual switch is stopped, the movement of the window in the closing direction is stopped in the same manner.

When an automatic operation of simultaneously operating any one of the switch units, for example, an opening direction automatic switch and any of the manual switches for performing the same operation, for example, an opening direction manual switch, is performed. The operation states are transmitted to the control unit, and a drive signal corresponding to the operation of the opening direction auto switch and the opening direction manual switch is output from the control unit, and the drive signal is supplied to the motor drive unit. The motor driving unit outputs a motor rotation switching signal in response to the driving signal, and the motor rotation switching signal is supplied to the relay control unit. The relay control unit switches the polarity of power supplied to the window opening / closing motor in response to the motor rotation switching signal, and rotates the window opening / closing motor in one direction so as to move the window in the opening direction. In this case, even if the operation of the opening direction auto switch and the opening direction manual switch is stopped, the control unit continues the movement of the window in the opening direction without stopping the rotation of the window opening / closing motor. When the is moved to the fully open position, the rotation of the window opening / closing motor is stopped, and the movement of the window is stopped.

Similarly, in the case of the automatic operation in which the closing direction auto switch and the closing direction manual switch of the switch section are simultaneously operated, the window opening / closing motor rotates in the other direction to close the window in a similar manner. Move in the direction. In this case as well, even if the operation of the closing direction auto switch and the closing direction manual switch is stopped, the control unit continues the movement of the window in the closing direction without stopping the rotation of the window opening / closing motor. When the window is moved to the fully closed position, the rotation of the window opening / closing motor is stopped, and the movement of the window is stopped.

By the way, as one of the normal operation modes of the power window device, an automatic operation is performed, and when the window is moving in the opening direction or the closing direction, the automatic operation is released and the window is opened. There is a case where it is desired to stop the movement in the opening direction or the closing direction halfway, or a case in which the movement in the closing direction or the opening direction is desired to be stopped.

In the known power window device,
When executing such an operation mode, the following operation is performed.

For example, when the closing direction automatic switch and the closing direction manual switch are simultaneously operated to perform the automatic operation of moving the window in the closing direction, the movement of the window in the closing direction is stopped or the window is opened in the opening direction. In order to move the opening direction manual switch, the closing direction auto switch and the closing direction manual switch are stopped, and then the opening direction manual switch is operated. Then, when the opening direction manual switch is operated, the window that has been moving in the closing direction is immediately stopped, and after a short time, for example, 0.2 to 0.3 seconds, the window is now turned on. It moves in the opening direction. In this case, the operation time of the opening direction manual switch indicates that the window is stopped.
The window can be stopped at that position by operating the opening direction manual switch so that the operation is completed within a minute time of about 2 to 0.3 seconds. By operating the opening direction manual switch so as to exceed the minute time of about 0.2 to 0.3 seconds when the window is stopped, the window can be moved in the opening direction.

When the direction of movement of the window is reversed, the window is stopped for a short time of about 0.2 to 0.3 seconds because the rotation of the motor for opening and closing the window is reversed. This is to prevent the relay control unit from being damaged when an excessive current is supplied to the relay control unit because an excessive current is generated from the window opening / closing motor.

[0012]

The above-mentioned known power window device has a manual switch (hereinafter referred to as a manual switch for moving the manual switch in a reverse direction) when the automatic operation is being performed. By operating a manual switch)
When the movement of the window is stopped, the time during which the movement of the window is stopped after the reverse manual switch is operated is a very short time of about 0.2 to 0.3 seconds. It is extremely difficult to complete the operation of the manual switch. When the operation of the reverse manual switch is completed, the window has often moved in the opposite direction.

As described above, in the known power window device, it is difficult to stop the window moving by the automatic operation immediately by operating the reverse manual switch, and it cannot be said that the window device is excellent in operability.

On the other hand, in the known power window device, a small time of about 0.2 to 0.3 seconds during which the movement of the window is stopped is not provided. A type in which the window is moved in the opposite direction immediately after the operation is also known.

However, in the power window device of this type, it is more difficult to immediately stop the window moving by the automatic operation by operating the reverse manual switch. It cannot be said that it is excellent.

The present invention has been made in view of such a technical background, and an object of the present invention is to provide an excellent operation method capable of immediately stopping a window moving by an automatic operation by operating a manual switch. It is an object of the present invention to provide a power window device having a characteristic.

Or a control unit that outputs a drive signal corresponding to the operation of each auto switch, a motor drive unit that outputs a rotation switching signal in response to the drive signal, a window opening / closing motor whose rotation direction is switched by the rotation switching signal, A time measurement unit that measures time by driving the control unit, wherein the control unit operates one of the switch units, and when the window is moving in one direction, the one that moves the window in the other direction. When the manual switch is operated, the movement of the window is stopped via the motor drive unit,
Start the time measurement by driving the time measurement unit, if the end of the operation of one manual switch is detected before the time measurement reaches a predetermined measurement value, the window is stopped,
When the operation of one of the manual switches is detected to continue after the time measurement reaches a predetermined measurement value, the stopped window is moved in the other direction.

With such a configuration, when the window is moved in one direction by the automatic operation, when one manual switch for moving the window in the other direction is operated, the movement of the window is stopped, and at the same time, the time measuring unit is operated. Is used to measure the time, and after the operator of the manual switch starts the operation of the manual switch by the time measurement, one manual switch is reached before reaching a predetermined measurement value that can determine whether or not to end the operation. By ending the operation, the window can be stopped at that position.On the other hand, if the operation of one manual switch is continued until the time measurement reaches a predetermined measurement value, the window is stopped. A power window device which can be moved in the other direction later and has excellent operability can be obtained.

Further, in the power window device according to the present invention, it is preferable that the predetermined measured value is configured to be between 0.3 and 1.0 second.

With such a configuration, if the predetermined measurement value is between 0.3 and 1.0 second, after the operator of the manual switch starts operating the manual switch, it is determined whether or not to end the operation. Is within the range in which the operator can immediately judge, and the period during which the window is stopped does not matter to the operator.

The time t0 earlier period, an initial state, the manual-up switch 1 _1, manual down switch 1 _2, the auto-up switch 1 _3, located in the automatic down switch 1 ₄ is a non-operation state (off), Wind When the opening / closing motor 5 is in a rotation stop state (stop),
The window does not move in either direction.

[0034] When the time becomes t0, the operating manual down switch 1 ₂ is the state of the manual down switch 1 ₂ is switched from off to on. In this case, the time t
Period from 0 to time t1, the manual down switch 1 ₂ Operation conditions determined period after the operation, even by operating the manual down switch 1 _2, immediately the operation is not enabled.

[0035] When the time becomes t1, the operation state determined period following a manual down switch 1 ₂ operation elapsed, operation of the manual down switch 1 ₂ is enabled. At this time, the opening / closing motor 5 starts rotating in the window-down (window-opening) direction, and enters a manual-down operation state.

[0036] When the time becomes t2, the automatic down switch 1 ₄ is operated, the state of the automatic down switch 1 ₄ is switched from off to on. In this case, the period from time t2 to time t3 is an automatic down switch 1 ₄ operation state determined period after the operation, even by operating the automatic down switch 1 _4, immediately the operation is not enabled.

[0037] At time t3, the operation state determined period of automatic down switch 1 ₄ after the operation has elapsed, the operation of the automatic down switch 1 ₄ is enabled. At this time, the opening / closing motor 5 continues to rotate in the window down (window open) direction, and switches from the manual down operation state to the auto down operation state.

[0038] Between time t3 of time t4, the operation of the manual down switch 1 ₂ is completed, the operation of the automatic down switch 1 ₄ also ends.

At time t4, the window moves to the fully open position and stops at that position, and the auto-down operation state is canceled (released).

The period from the time t4 to time t5 is returned to the initial state, the manual-up switch 1 _1, manual down switch 1 _2, the auto-up switch 1 _3,
Located automatic down switch 1 ₄ non-operated state (off), the window opening and closing motor 5 is in the rotation stop state (stop), the window does not move in either direction.

[0041] When it is time t5, is operated manual-up switch 1 _1, manual-up switch 1 ₁ of the state is switched from the off state to the on state. In this case, the time t
Period of from 5 to time t6 is a manual-up switch 1 ₁ operation state determined period of time after the operation, even by operating the manual-up switch 1 _1, immediately the operation is not enabled.

[0042] When it is time t6, elapsed operation state determined period of time after the manual-up switch 1 ₁ operation, manual-up switch 1 ₁ of the operation is enabled. At this time, the opening / closing motor 5 starts rotating in the window-up (window-closed) direction, and enters a manual-up operation state.

[0043] At time t7, the auto-up switch 1 ₃ is operated, the state of the auto-up switch 1 ₃ is switched from off to on. In this case, the period from time t7 to time t8 is the auto-up switch 1 ₃ operating state determined period after the operation, even by operating the auto-up switch 1 _3, immediately the operation is not enabled.

[0044] When it is time t8, operation state vesting period of the auto-up switch 1 ₃ after the operation has elapsed, the operation of the auto-up switch 1 ₃ is enabled. At this time, the opening / closing motor 5 continues to rotate in the window-up (window-closed) direction, and switches from the manual-up operation state to the auto-up operation state.

[0045] Between time t8 of time t9, manual-up switch 1 ₁ of the operation is completed, the operation of the auto-up switch 1 ₃ is also terminated.

At time t9, the manual up switch ₁₁ is operated. At this time, the state has been switched to the auto-up operation state, and the operation of the switch for moving the window in the same direction is not accepted. Therefore, there is no change in the rotation direction of the opening / closing motor 5 and the moving direction of the window.

[0047] When it is time t10, manual-up switch 1 ₁ of the operation is completed. However, since not received operation of the manual up switch 1 _1, still there is no change in the moving direction of the rotation direction and the window opening and closing motor 5.

[0048] When it is time t11, manual down switch 1 ₂ is operated, manual down switch 1 ₂
Is switched from off to on. Again, the period from time t11 to time t12, the manual down switch 1 ₂ Operation conditions determined period after the operation, even by operating the manual down switch 1 _2, immediately the operation is not enabled.

[0049] When it is time t12, elapsed operation state determined period of time after the manual down switch 1 ₂ operation, operation of the manual down switch 1 ₂ is enabled. By operating the manual down switch 1 _2, the rotation of the opening and closing motor 5 is stopped, the window is stopped at that position.
At this time, from the auto-up operation state, a reversal standby period of the window opening / closing motor 5 is started, and the reversal standby period of the window opening / closing motor 5 is continued from time t12 to time t13.

At time t13, the reversal standby period of the window opening / closing motor 5 elapses. At this time, since the manual down switch 1 ₂ is operated continuously, the opening and closing motor 5 is rotated window down (window-opening) direction to move the window within the opening direction, the manual-down operation.

[0051] When the operation of the manual down switch 1 ₂ is completed before the lapse of the inverted standby period of the window opening and closing motor 5, after which the rotation of the wind-down (window-opening) direction of the opening and closing motor 5 is performed The window is not moved in the opening direction. And it does not enter the manual down operation state.

During the reversal standby period of the window opening / closing motor 5, any one of the manual switches 1 ₁ , 1
₂ is operated, the time is measured by the time measuring unit 6, and the period until the time measurement reaches a predetermined measurement value,
Since it is necessary for the operator to be able to determine whether the operation of any one of the manual switches 1 ₁ and 1 ₂ is to be completed within the reversal standby period or to continue the operation beyond the reversal standby period, the predetermined measurement is performed. By adjusting the value, the reversal waiting period is about 1 second, preferably 0.3 second.
To within 1.0 second.

By setting such a reversal standby period, when the window is moving by the automatic operation,
By operating the operator manual switch 1 ₁ is moved in a direction opposite to the moving direction of the window, 1 _2, it is possible or to immediately move or window or to stop the movement of the window in the opposite direction, A power window device having excellent operability can be obtained.

[0054]

As described above, according to the present invention, when the window is moved in one direction by the automatic operation,
When one manual switch that moves the window in the other direction is operated, the movement of the window stops, and at the same time,
The time measurement unit measures the time, and the time measurement starts after the operator of the manual switch starts operating the manual switch, and before the predetermined measurement value that can determine whether to end the operation is reached. When the operation of one manual switch is completed, the window can be stopped at that position.On the other hand, when the operation of one manual switch is continued until the time measurement reaches a predetermined measurement value, the window is opened. After being stopped, it can be moved in the other direction, and there is an effect that a power window device excellent in operability can be obtained.
