Abstract

PROBLEM TO BE SOLVED: To shortly and accurately set a non-inversion region where automatic inversion of a window caused due to catching-in of foreign matter is inhibitted, that is, an upper limit position of an inversion region where automatic inversion of the window is permitted by utilizing a jig and prevent initial setting of the inversion region while the jig is not attached. SOLUTION: A window fully closed line and a boundary line between an inversion region and a non-inversion region are indicated by L1 and L2, respectively. A jig G having a height corresponding to a height of the non-inversion region is caught in by a window 10 as a dummy of a foreign matter I. The number of pulses corresponding to the number of rotation of a drive motor 14 of the window 10 is output from the drive motor 14 thereof. While the window 10 is lifted toward a fully closed position, the number of pulses generated between a position M where operation conditions of a limit switch provided in the inversion region are changed and a position where the jig G is caught in after that is memorized as a distance between the position M and the boundary line L2. When the jig G is not caught, memorization is inhibitted.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a power window control device.

[0002]

2. Description of the Related Art In a power window in which an occupant operates a switch to open and close a window, a power window is usually used.
The driver's window opening / closing switch has an auto-up command function. That is, once the auto-up operation is performed by the occupant, the window is driven to the fully closed state even after the operation of the open / close switch is stopped.

[0003] As described above, when the window is driven to the fully closed state by the auto-up function, when the window is caught by a foreign substance, the window has an automatic inversion function of automatically inverting the window in the opening direction by a predetermined amount. This is generally the case (see, for example, JP-A-7-317430).
In general, the detection of the foreign material being caught is determined based on an increase in the driving load of the window.

[0004] The above-described automatic reversal due to the foreign substance trapping is performed only when the window is in a predetermined reversal area, and when the window is in a non-reversal area set from the fully closed state to the vicinity of the fully closed state. The reversal is prevented from being performed (prevention of an automatic reversal due to an erroneous determination that an increase in the window drive load when the window is fully closed is a foreign matter trapped therein).

The above-mentioned non-reversal area compensates for the requirement to reliably prevent automatic reversal in the fully closed state and the deviation of the correspondence between the window drive position and the fully closed position of the window caused by window assembly errors and the like. Therefore, the setting is made in a range from the fully closed window to the vicinity of the fully closed window (substantially fully closed).

[0006]

By the way, recently,
It has been strongly desired that the above-mentioned non-inversion region be made as small as possible, that is, that the inversion region be sufficiently enlarged in the closing direction. From such a viewpoint, the applicant has developed a technique of accurately setting a non-inversion area according to the height of a jig by sandwiching a jig for setting a non-inversion area having a predetermined height in a window. did. In other words, a type in which the window drive position when the jig is sandwiched is set as the boundary position between the inversion area and the non-inversion area has been developed (initial setting of the inversion area).

When the non-reversal area is set using the above-mentioned jig, that is, when the reversal area is set, a situation in which the jig is forgotten to be mounted may occur. If you forget to install the jig,
Until the fully closed state of the window is erroneously set as the reversal area, the increase in the drive load of the window in the fully closed state is erroneously determined as foreign matter trapping, and it is automatically reversed, and it is possible to completely close the window. Impossible.

The present invention has been made in view of the above circumstances, and an object of the present invention is to cause the operator to forget to attach the jig when the jig is inserted into the window to initialize the reversal area. It is an object of the present invention to provide a power window control device capable of preventing erroneous initial setting.

[0009]

In order to achieve the above-mentioned object, the present invention adopts the following solution. That is, as described in claim 1 of the claims, the window is driven in the closing direction according to the switch operation by the occupant, and is set excluding the non-reversal region from the fully closed window to the vicinity of the fully closed window. The window is automatically inverted when foreign matter is caught by the window in a predetermined inversion area.
In the window control device, initial setting of an inversion area for calculating and storing the inversion area is performed according to a window driving position when the non-inversion area setting jig is sandwiched between windows (initial setting means). Alternatively, when it is detected that the jig is not set, the initial setting of the inversion area is prohibited (prohibiting means). Preferred embodiments on the premise of the above solution are as described in claim 2 and the following claims.

[0010]

According to the first aspect of the present invention, the non-reversal area is minimized by using the jig, that is, the reversal area is sufficiently and accurately enlarged in the window closing direction, and the reversal caused by forgetting to mount the jig is achieved. Erroneous initialization of the area can be prevented.

According to the second aspect, since it is notified that the initial setting is not performed, it is possible to reliably prevent a situation where the initial setting of the inversion area is not performed. According to the third aspect, since the initial setting of the inversion area is not executed unless the predetermined operation is performed, it is preferable to prevent a situation where the initial setting of the inversion area is carelessly performed.

According to the fourth aspect, a command for executing the initial setting of the inversion area can be issued by effectively using the window opening / closing switch. According to the fifth aspect, the fact that the window is driven in the closing direction by a predetermined amount or more from the operating state change position of the limit switch can be easily and accurately detected when the jig is left unattended. Further, after the initial setting of the inversion area is completed, it is possible to check, that is, confirm the operating position change position of the limit switch as the predetermined drive position of the window.

According to the sixth aspect, the positional relationship between the window position when the jig is sandwiched and the mounting position of the limit switch is clarified, and after the initial setting, the operating state change position of the limit switch is used as a reference. , The inverted region can be accurately known. Of course, after the initial setting of the inversion area is completed, the operating state change position of the limit switch can be checked or confirmed as the predetermined drive position of the window.

The slider 13 presses the operating piece 20a of the limit switch 20, and the limit switch 20 is turned off (FIGS. 5 and 6). Thereafter, the window 10 is kept off until the window 10 is fully closed.

FIG. 7 shows a driver's seat open / close switch 2a as a representative of the open / close switches 2a to 5a. The open / close switch 2a includes a total of four open / close switches 22 to 25 corresponding to the numbers of the doors 2 to 5, respectively. Each open / close switch 22 ~
Numeral 24 denotes a vertical swing type, and an open / close switch 22 for the driver's seat is of a five-position type, and is self-returned to an intermediate neutral position. That is, when the swing operation is performed slightly upward from the neutral position (one-step upward operation), the manual up instruction position is set to raise (close direction drive) the window 10 during the operation (time). When the swing operation is performed strongly upward (two-step upward operation) from the neutral position, the window 10 is set to the auto-up command position in which the window 10 is automatically driven to the fully closed position even if the operating force is released thereafter.

When the open / close switch 22 is slightly swayed downward from the neutral position (one-step down operation), a manual down command position for lowering (driving in the opening direction) the window 10 during the operation (time). Becomes When the swing operation is performed strongly downward from the neutral position (two-step downward operation), the window 10 is set to the auto-down command position in which the window 10 is automatically driven to the fully open position even if the operating force is released.

FIG. 8 shows a control system for the motor 14, paying attention to the driver's seat door 2. In FIG. 8, U is a control unit (controller) configured using a microcomputer, and includes a CPU, a RO,
M, RAM and the like. Control unit U
Is supplied with a command signal from the open / close switch 22 and a position signal (ON or OF) from the limit switch 20.
F), and a pulse signal corresponding to the number of rotations from the motor 14 is input. That is, the motor 14 is a pulse type having a built-in pulse generator, and outputs a number of pulses corresponding to the number of rotations. Further, the control unit U outputs a drive signal for forward rotation or reverse rotation (up or down of the window 10) to the motor 14 via the relay 27. The control unit U receives ON / OFF signals from an ignition switch 35 for control described later, and also controls an alarm device 36 such as a buzzer or a lamp.

Next, referring to FIG.
Non-inversion area, inversion area, and limit switch 20
Will be described. First, when a foreign object is caught while the window 10 is rising (driving in the closing direction),
The window 10 is automatically inverted in the opening direction by a predetermined amount,
Entrapment is eliminated. The area in which the automatic inversion is permitted is the inversion area, and the area in which the automatic inversion is prohibited from the fully closed state of the window 10 to the vicinity of the fully closed area is the non-inverted area.

In FIG. 2, the height position of the upper end of the window 10 when the window 10 is fully closed is shown as a fully closed line L1, and the boundary line between the inversion area and the non-inversion area is shown by a symbol L2. The upper end line (closing direction line) of the inversion area is the boundary line L2. The limit switch 20 is set to a position near the boundary line L2 and surely below the boundary line L2 (for example, a position 20 to 60 mm below the boundary line L2 and in a reversal area). .

Next, with reference to FIG. 9, a description will be given of foreign object entrapment detection and automatic reversal, and then an initial setting of an inversion area (non-inversion area). Is detected, for example, when the driving load of the motor 14 is increased in the inversion area, and more specifically, when the pulse signal from the motor 14 does not change for a predetermined time or more, the detection is performed. Can be. When a foreign object is detected in the inversion area, a drive inversion signal (opening direction drive signal) is output from the control unit U to the motor 14, and the window 10 is moved in the opening direction by a predetermined amount (for example, 20 degrees).
0 mm).

In FIG. 9, when the window 10 is raised from its fully open position, the operating state of the limit switch 20 is changed from ON to OFF at time t1. Thereafter, when the pinch of a foreign substance indicated by reference numeral I in FIG. 2 is detected in the inversion area, the pulse signal from the motor 14 has been present (changed), and no pulse signal is present. It changes to the (unchanged) state. That is, the pulse signal does not exist because the rotation of the motor 14 is forcibly stopped by the foreign substance being caught. When this pulse signal is not present at the time point t3 when the predetermined time has elapsed, the opening direction drive signal is output to the motor 14, the window 10 is automatically inverted, and the pulse signal is output from the motor 14 with the trowel. Will be generated again. When the driving of the window 10 in the opening direction proceeds, the limit switch 20 is turned off.
F is changed to ON, and then a predetermined amount of window 1
The motor 14 is stopped at the position where 0 is driven in the opening direction.

Here, the drive position of the motor 14 can be known by counting (monitoring) the number of pulses generated from the motor 14. The deviation of the correspondence relationship between the number of count pulses and the opening / closing position of the window 10 due to the step-out of the motor 14 is determined by changing the operation state change position (indicated by the symbol M in FIG. 2) of the limit switch 20 to the predetermined absolute value of the window 10. Corrected by adjusting as position.

By accurately associating the mounting position of the limit switch 20 with the fully closed position of the window 10 (fully closed line L1 or boundary line L2), the operating state change position of the limit switch 20 and the fully closed position of the window 10 are determined. The absolute positional relationship based on the position is accurately correlated. In consideration of the assembly error of the window 10 and the mounting position error of the limit switch 20, the line L
1, the initial setting of L2, that is, the initial setting of the non-inversion area and the inversion area is performed as follows.

First, for the initial setting, FIGS.
A jig G as a substitute for the foreign substance I as shown in FIG. The jig G has a fitting groove 31 fitted to the upper end of the window 10, and the fitting groove 31 is fitted to the upper end edge of the window 10 without looseness.
Is raised, the jig G is sandwiched by the window 10 (see FIGS. 2 and 12). FIG.
In FIG. 2, reference numeral 32 denotes a window sash, and 33 denotes a weather strip. Also, the jig G is formed of a synthetic resin or the like so that the jig G is not easily deformed by the force of the pinching of the window 10, and the jig G is provided on the upper surface opposed thereto so as not to damage the weather strip 33. No sharp edges are present.

When the jig G is sandwiched between the windows 10, the height of the jig G is set so that the deviation between the lines L1 and L2 becomes the length of the non-inversion area to be set. (4 mm in the embodiment). At this time, in FIG. 9, the length corresponding to the number of output pulses from the motor 14 between t1 and t2 or between t3 and t4 is determined by the operation state change position M of the limit switch 20 and the boundary line L
This corresponds to a deviation (length) from 2. Therefore, the length from the time when the change in the operating state of the limit switch 20 is detected to the boundary line L2 or the fully closed line L1 can be accurately known by counting the number of output pulses of the motor 14. The initial setting of the inversion region is performed between t1 and t2 or between t3 and t, as described above.
This is done by calculating and storing the number of output pulses from the motor 14 between four.

Next, the contents of control by the control unit U will be described with reference to FIG. 13 and subsequent figures. In the following description, Q is a step, Y in the figure means YES, and N is NO. Means The control contents to be described below are roughly classified into the initial setting of the inversion area, the control of opening and closing the window, and the control of determining the failure of the limit switch 20. The opening and closing drive of the window 10 is performed as follows.
Other than when the ignition switch 35 is turned on, it is enabled within a predetermined time (for example, 40 seconds) after the ignition switch is turned off, that is, within an OFF timer set time.

Description of FIG. 13 FIG. 13 is a control for discriminating whether to control the initial setting of the inversion area or to control the opening and closing of the window 10. That is, in Q1, the ignition switch 35
When the flag is determined to be N, the flag is set to 0 to indicate that the ignition switch 35 is ON in Q2.
After the resetting, in Q3, it is determined whether or not a predetermined operation meaning an instruction to perform the initial setting of the inversion area has been performed. In the embodiment, the predetermined operation is set such that the opening operation (auto-up operation) and the closing operation (auto-down operation) of the open / close switch 22 are performed in a predetermined procedure. More specifically, the predetermined operation is performed when the auto-down operation is performed once, then the auto-up operation is performed twice, and then the auto-down operation is continuously performed three times. When the predetermined operation is performed, that is, when the determination in Q3 is YES, in Q4, the control of the initial setting of the inversion area is performed as described later.

If the determination in Q1 is NO, in Q5, it is determined whether or not a predetermined time has elapsed since the ignition switch 35 was turned off, that is, whether or not the OFF timer set time for opening and closing the window 10 can be determined. Is determined. If the determination in Q5 is YES, the flag is set to 1 in Q6, and then the opening / closing control of the window 10 described later in Q7 is performed. N in the determination of Q3
Also in the case of O, the process shifts to Q7. If the determination in Q5 is NO, the process ends.

Description of FIG. 14 FIG. 14 shows details of Q7 in FIG. In the control shown in FIG. 14, basically, when the ignition switch 35 is ON, automatic reversal due to foreign matter trapping is performed during auto-up, and automatic reversal due to foreign substance trapping is not performed during manual up. Also, within the OFF timer set time which is within a predetermined time after the ignition switch 35 is turned off,
In both the auto-up and the manual-up, automatic reversal is performed by pinching foreign matter.

On the premise of the above, it is determined in Q11 whether a failure affecting the opening / closing control of the window 20 (a failure of the limit switch 20 in the embodiment) has been detected. When
In Q12, it is determined whether an auto-up command has been issued. If YES in Q12, it is determined in Q13 whether a failure has been detected again, and if NO in Q13, it is determined in Q14 whether or not the vehicle is in an inversion area. If the determination in Q14 is YES, in Q15, it is determined whether or not a foreign object entrapment is detected. If the determination in Q15 is YES, Q
At 16, the window 10 has a predetermined amount (eg, 200
mm) Automatically reversed in the opening direction.

If NO in Q12, Q17
It is determined whether there is a manual up command. If the determination in Q17 is YES, it is determined in Q18 whether the flag is 1. This Q18
If the determination is YES, the ignition switch 35
Is within a predetermined period of time after the switch is turned off, and in this case, the process proceeds to Q14 (control with automatic reversal due to pinching of foreign matter during manual up command). When the determination in Q17 is NO, when the determination in Q18 is NO, or when Q1
If NO in the determination of 4, the process proceeds to Q19, respectively.
The opening / closing drive of the window 10 is performed based on the operation of the open / close switch, but the automatic inversion is not performed.

If the determination in Q11 is YES, Q2
At 0, the alarm 36 is activated and the process returns to Q11.
When the determination in Q13 is YES, the window 10 is automatically inverted by a predetermined amount in Q21,
In, the alarm 36 is activated.

Description of FIG. 15 FIG. 15 shows details of Q4 in FIG. In FIG. 15, the initial setting of the inversion area using the jig G is performed, but the initial setting of the inversion area based on the pulse count number between t1 and t2 in FIG. 9 is performed.

First, when it is determined in Q31 that the auto-up command has been issued, the window 10 is automatically raised in Q32, and thereafter in Q33,
It is determined whether or not the limit switch 20 has changed to the OFF state. When the determination in Q33 is YES (t1 in FIG. 9)
At the time point), the number of pulses from the motor 14 is counted in Q34. In Q35, it is determined whether or not the pulse count number is larger than a predetermined value (for example, a length corresponding to the length of the window 10 driven in the closing direction of 10 cm and larger than the size of the non-inversion area). If the determination in Q35 is NO, it is determined whether or not the foreign object entrapment is detected in Q36. Initially, the determination of Q36 is NO and Q3
Returning to FIG. 4, as the window 10 rises, the jig G as a dummy foreign substance is detected soon, so that
The determination in Q36 is YES.

When the determination in Q36 is YES (t3 in FIG. 9)
At (time point), the number of pulses counted from t1 to t2 in Q37 is stored (the number of pulses from the operation change position M of the limit switch 20 to the boundary line L2). Thereafter, after the number of pulses counted in Q38 is cleared to 0, in Q39, the window 10 is driven in the opening direction by a predetermined amount (for example, 200 mm). The process of Q39 is performed to inform that the initial setting of the reversal area has been performed, that is, the storage in Q37 has been performed by automatically reversing the window 10 in the opening direction. It is also used to remove the jig G.

If NO in Q33, Q40
In, it is determined whether or not a foreign object has been trapped. If the determination in Q40 is NO, the process returns to Q33. If the determination in Q40 is YES, the initial setting of the inversion area is not performed normally, so the flow shifts to Q41 and the driving of the window 10 is stopped. If the determination in Q35 is YES, the limit switch 20 may be faulty. In this case, after the pulse number counted in Q42 is cleared to 0, the process proceeds to Q41.

Description of FIG. 16 FIG. 16 shows details of Q4 in FIG. 13, and is an embodiment different from FIG. In FIG. 16, the initial setting of the inversion area using the jig G is performed.
The initial setting of the inversion area based on the pulse count number between t3 and t4 in FIG. 9 is performed.

First, Q51, Q52, Q53, Q61
Corresponds to Q31, Q32, Q33, and Q40 in FIG. 15, and a duplicate description thereof will be omitted. When it is confirmed by the determination in Q53 that the limit switch 20 has been turned OFF, it is determined in Q54 whether or not the jig G has been caught. If the determination in Q54 is YES (time t3 in FIG. 9), the window 10 is automatically inverted in the opening direction in Q55, and then the number of pulses from the motor 14 is counted in Q56. Q5
It is determined whether or not the number of pulses counted in 7 is larger than a predetermined value (corresponding to Q35 in FIG. 15).
If the determination in Step 7 is NO, it is determined in Q58 whether or not the limit switch 20 has changed to the ON state. If the determination in Q59 is NO, the process returns to Q56.

If the determination in Q58 is YES, the number of pulses counted between t3 and t4 is stored in Q59 (corresponding to Q37 in FIG. 15), and thereafter the number of pulses counted is cleared to 0. At the same time, the alarm 36 is activated to notify that the inversion area has been initialized. If the determination in Q57 is YES, it means that the limit switch 20 has failed and the initial setting is not possible. In this case, the process proceeds to Q62, and the driving of the window 10 is stopped.

Description of FIGS. 17 and 18 FIGS. 17 and 18 are for detecting a failure of the limit switch 20, and show details of failure detection of Q11 and Q13 in FIG. However, the failure in Q11 and Q13 is not limited to the failure of the limit switch 20.

The failure detection of the limit switch 20 includes an ON failure fixed in the ON state and an OFF failure fixed in the OFF state, and both failure determinations are cleared in FIGS. 17 and 18 (failure determination). Control). The ON failure of the limit switch 20 is defined as a case where the window 10 is driven by a predetermined amount or more while the limit switch 20 is in the ON state.
The value is smaller than the total driving amount from the fully closed to the fully opened window 10 and larger than the window driving amount from the limit switch operating state change position M and the window fully opened position, which is equivalent to 50 cm in the embodiment. ).

The OFF failure of the limit switch 20 is determined when the window 10 is driven by a predetermined amount or more while the limit switch 20 is in the OFF state. Set to a value greater than the length to the fully closed position,
10 cm in the embodiment). The failure determination is cleared when the operation state of the limit switch 20 changes from ON to OFF or from OFF to ON.

Assuming the above, first, as shown in FIG.
At 71, it is determined whether or not the window 10 is being driven in the up direction in which it is driven in the closing direction. If the determination in Q71 is YES, in Q72, it is determined whether or not the limit switch 20 is currently ON. If the determination in Q72 is YES, after the number of pulses from the motor 14 is counted in Q73, it is determined in Q74 whether or not the counted number of pulses is larger than a predetermined value (corresponding to 50 cm). . If the determination in Q74 is YES, in Q75, the limit switch 2
After it is determined that 0 is an ON failure that has been stuck in the ON state, in Q76, the number of pulses counted is 0.
Is cleared.

If NO in Q72, it is determined in Q77 whether or not the limit switch 20 has just been changed from ON to OFF. If the determination in Q77 is YES, after the determination of the ON failure is cleared in Q78, the process proceeds to Q76. When the determination in Q77 is NO, the limit switch 20 is in the OFF state. In this case, after the number of pulses from the motor 14 is counted in Q79, the counted number of pulses is reduced to a predetermined value in Q80. (Equivalent to 10 cm) is determined. YES in this determination of Q80
, The limit switch 20 is set to O in Q81.
It is determined that the OFF failure is fixed in the FF state. If the determination in Q74 is NO or the determination in Q80 is NO, the process ends without performing the failure determination and the failure determination clear.

If the determination in Q81 is NO, FIG.
The processing is shifted to Q91 of FIG.
0 corresponds to FIG. 17 when it is driven in the downward direction, that is, in the opening direction. First, in Q91 of FIG. 18, it is determined whether or not the window 10 is being driven down in the opening direction. In the determination of Q91, YE
In the case of S, in Q92, the current limit switch 2
It is determined whether 0 is in the OFF state. This Q92
If the determination is YES, in Q93, the motor 14
After counting the number of pulses from
It is determined whether or not the counted number of pulses is larger than a predetermined value (corresponding to 10 cm). If the determination in Q94 is YES, in Q95, the limit switch 20 is turned off.
After it is determined that it is at the time of the OFF failure fixed in the F state,
In Q96, the counted number of pulses is cleared to zero.

If NO in Q92, it is determined in Q97 whether or not the limit switch 20 has just been changed from OFF to ON. If the determination in Q97 is YES, after the determination of the OFF failure is cleared in Q98, the process proceeds to Q96. When the determination in Q97 is NO, the limit switch 20 is in the ON state. In this case, after the number of pulses from the motor 14 is counted in Q99, in Q100,
It is determined whether or not the counted number of pulses is larger than a predetermined value (corresponding to 50 cm). In the determination of Q100, Y
In the case of ES, in Q101, the limit switch 2
It is determined that 0 is an ON failure fixed in the ON state.
If the determination in Q91 is NO, the determination in Q94 is NO, or the determination in Q100 is NO, the process ends without performing the failure determination and the failure determination clear.

Although the embodiment has been described above, the present invention is not limited to this, and includes, for example, the following case. The jig G may be configured to be detachably fixed to the window sash 32 without being fitted to the window 10. Automatic reversal when foreign object is detected
It is also possible to perform all the operations at the time of a manual up command, or to limit the automatic inversion at the time of the manual up operation only at the time of the auto up command. The automatic reversal due to the foreign substance being caught can be applied not only to the driver's seat window but also to other windows. Further, the present invention is not limited to the side door window, and may be similarly applied to an appropriate window that is opened and closed in response to an operation of a manually operated open / close switch, such as a back door window.

Each member such as each step or switch shown in the flowchart can be expressed by adding a name of the means to a higher-level expression of its function. In addition, the object of the present invention is not limited to what is explicitly specified, but also implicitly includes providing what is expressed as substantially preferable or advantageous. Further, the present invention can be expressed as a control method.
