Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a power window control device.
[0002]
[Prior art]
In a power window that opens and closes a window by a switch operation by an occupant, a window opening / closing switch for a driver's seat usually has an auto up command function. In other words, once the auto-up operation is performed by the occupant, the window is driven to the fully closed state even if the operation of the open / close switch is stopped thereafter. As described above, when the window is driven to the fully closed state by the auto-up function, when the foreign object is caught in the window, it is common to have an automatic inversion function that automatically inverts the window in a predetermined amount in the opening direction. (See, for example, JP-A-7-317430). Detection of foreign object pinching is generally determined by an increase in the window driving load.
[0003]
As the window opening / closing switch, a manual up switch is generally provided for driving the window in the closing direction only while an operation by the passenger is being performed. In Japanese Patent Laid-Open No. 6-81540, assuming that the ignition switch is on, the window is automatically reversed in the opening direction even when foreign object pinching is detected due to the operation of the manual up switch. What to do has been proposed.
[0004]
Furthermore, in recent automobiles, the window can often be driven to open and close within a predetermined time after the ignition switch is turned off. Japanese Patent Application Laid-Open No. 8-254074 discloses a predetermined time after the ignition switch is turned off. It has been proposed to automatically invert a window when a foreign object is detected in time.
[0005]
[Problems to be solved by the invention]
Although it is preferable in terms of safety to automatically reverse the window in the opening direction when the foreign object is sandwiched, it is easy to cause a situation where the window is erroneously automatically reversed even though the foreign object is not sandwiched. For this reason, it is not preferable to allow automatic reversal unnecessarily, and there is a problem of how to satisfy safety ensuring and prevention of malfunction of automatic reversal at a high level.
[0006]
The present invention has been made in consideration of the above circumstances, and its purpose is to automatically reverse the window in the opening direction when foreign object pinching is detected. It is an object of the present invention to provide a power window control device which can be satisfied at a high level.
[0007]

Even when the ignition switch is in the OFF state, the window is driven to close in response to the operation of the manual up switch under a predetermined condition (predetermined condition setting means),
The manual up switch is operated when the ignition switch is on. Has been Even when foreign object pinching is detected, the automatic reversal is prohibited (prohibiting means)
When foreign object pinching is detected when the ignition switch is OFF and the window is driven in the closing direction by operating the manual up switch, the automatic inversion is allowed (allowing means).
It is like that. A preferred mode based on the above solution is as set forth in claim 3.
[0008]
According to the first solution described above, driving the window in the closing direction by operating the manual up switch is originally a safe operation with a low risk of foreign object pinching, and the fact that the ignition switch is ON means that the driver Therefore, even if automatic reversal is prohibited, there is no safety problem, and it is unnecessary to perform automatic reversal. On the other hand, when the ignition switch is turned off, there is a high possibility that the driver is not present nearby. At this time, even when the manual up switch is operated, automatic reversal is allowed, which is extremely preferable for safety. It will be a thing.
[0009]
In order to achieve the above object, the present invention provides the following as a second solution. That is, as described in claim 2 in the scope of claims,
In the power window control device that automatically reverses the window in the opening direction when the foreign object is caught by the window,

Even when the ignition switch is in the OFF state, it is set so that the window is driven in the closing direction in accordance with the operation of the manual up switch and the auto up switch under a predetermined condition (predetermined condition setting means),
When the ignition switch is in an ON state, when a foreign object pinching is detected by driving in the window closing direction due to the operation of the auto up switch, the automatic reversal is allowed (first permitting means), while the manual up switch is turned on. When the foreign object pinching is detected by the window closing direction drive resulting from the operation, the automatic reversal is prohibited (prohibiting means),
When the ignition switch is in the OFF state, the automatic inversion is performed when foreign object pinching is detected both when the window is driven in the closing direction by the operation of the auto up switch and when the window is driven in the closing direction by the operation of the manual up switch. Allowed (second allowing means),
It is like that. A preferred mode based on the above solution is as set forth in claim 3.
[0010]
【The invention's effect】
According to the first aspect, both of ensuring safety and preventing malfunction of automatic reversal can be satisfied at a high level.

According to the third aspect of the present invention, the window can be opened / closed only within a predetermined time after the ignition switch is turned OFF, which is a set time of a so-called OFF timer.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
In FIG. 1, the automobile 1 has a pair of front and rear side doors 2 to 5 on left and right sides. The door 2 is for the driver's seat, the door 3 is for the passenger seat, the door 4 is for the right rear seat, and 5 is for the left rear seat. Each of the doors 2 to 5 is equipped with manually operated opening / closing switches 2a to 5a for instructing opening / closing of the window (window glass). Of these open / close switches 2a-5a, only the open / close switch 2a for the driver's seat door 2 also has open / close switches for the other doors 3-5.
[0012]
In FIG. 2, the driver's seat door 2 is shown as a representative of the doors 2 to 5, and a window that is opened and closed is indicated by reference numeral 10. A pair of front and rear window guides 11 and 12 are provided in the panel 6 of the door 2. The lower end of the window 10 is fixed to a slider 13 slidably attached to one guide 11, and the slider 13 is driven up and down by a motor 14 via a rotating drum 15 and an interlocking cable 16. As a result, the slider 13, that is, the window 10 is driven to open and close (up and down driving).
[0013]
3 to 6 show a regulator R formed of an assembly such as the guide 13 and the motor 14 for opening and closing the window 10. The interlocking cable 16 is an internal / external double type, and the inner cable is linked to the slider 13 and the rotary drum 15. In the regulator R, a limit switch 20 is held at a predetermined position of the upper end of the guide 11. The limit switch 20 is turned on and off by the slider 13, and when the slider 13 is at a position below the limit switch 20 as shown in FIGS. 3 and 4, the limit switch 20 is turned on. . While the slider 13, that is, the window 10 is moving up, the slider 13 presses the operating piece 20 a of the limit switch 20, and the limit switch 20 is turned off (FIGS. 5 and 6). The OFF state is maintained until the fully closed state.
[0014]
FIG. 7 shows a driver seat opening / closing switch 2a as a representative of the opening / closing switches 2a to 5a. The opening / closing switch 2a includes a total of four opening / closing switches 22-25 corresponding to the number of doors 2-5. Each of the open / close switches 22 to 24 is a vertical swing type, and the open / close switch 22 for the driver's seat is a 5-position type up and down, and is self-returned to an intermediate neutral position. . That is, when the light is swung upward (one step upward operation) from the neutral position, it is the manual up command position for raising (driving in the closing direction) the window 10 during the operation (time). When the swinging operation is performed strongly upward (two-step upward operation) from the neutral position, the window 10 becomes the auto up command position where the window 10 is automatically driven up to the fully closed position even if the operating force is released thereafter.
[0015]
When the open / close switch 22 is swung downward (one step downward) from the neutral position, it becomes a manual down command position for lowering (driving in the opening direction) the window 10 during the operation (time). When the swinging operation is performed strongly downward (two-step downward operation) from the neutral position, even if the operation force is released thereafter, the window 10 becomes the auto-down command position that is automatically lowered to the fully open position.
[0016]
Of the other opening / closing switches 23 to 25, 23 is for the passenger seat, 24 is for the right rear seat, and 25 is for the left rear seat. Each of the open / close switches 23 to 25 is a three-position type in the vertical direction, and is self-returned to an intermediate neutral position. Each of the open / close switches 23 to 25 is a manual for raising the window 10 (driving in the closing direction) only during the operation (time) when the light is swung upward (one step upward operation) from the neutral position. Up command position. In addition, each of the open / close switches 22 to 25 is manually down to move the window 10 downward (drive in the open direction) only during the operation (time) when the light is swung downward (one step downward operation) from the neutral position. It becomes the command position. The open / close switches 3a to 5a provided on the doors 3 to 5 are similar to the open / close switches 23, 24, or 25, respectively, and command manual up or manual down (auto up command). There is no auto down command).
[0017]
FIG. 8 shows a control system for the motor 14 focusing on the driver seat door 2. In FIG. 8, U is a control unit (controller) configured using a microcomputer, and includes a CPU, a ROM, a RAM, and the like. The control unit U receives a command signal from the open / close switch 22, a position signal from the limit switch 20 (ON or OFF signal), and a pulse signal corresponding to the rotational speed from the motor 14. . 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. The control unit U outputs a drive signal for normal 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 and OFF signals from the ignition switch 35 for control described later, and the control unit U controls an alarm device 36 such as a buzzer and a lamp.
[0018]
Next, with reference to FIG. 2, the non-inversion area, the inversion area, and the mounting position of the limit switch 20 of the window 10 will be described. First, when a foreign object is pinched while the window 10 is being lifted (driving direction drive), the window 10 is automatically reversed in the opening direction by a predetermined amount to eliminate the pinching. A region where this automatic reversal is permitted is a reversal region, and a region where automatic reversal is prohibited from the fully closed state to the fully closed region of the window 10 is a non-reversed region.
[0019]
In FIG. 2, the height position of the upper end of the window 10 when the window 10 is fully closed is indicated as a fully closed line L1, and the boundary line between the inversion region and the non-inversion region is indicated by a symbol L2. The upper end line (closed direction line) of the inversion area becomes the boundary line L2, and the lower end line (open direction end line) of the inversion area is indicated by reference numeral L3. The limit switch 20 is set to a position that is located 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 a position in the inversion region). .
[0020]
Next, the foreign object pinching detection and automatic reversal will be described with reference to FIG. 9, and then the initial setting of the reversal area (non-reversal area) will be described. In the foreign object nipping, the window 10 is driven in the closing direction. Sometimes, it can be detected by, for example, an increase in the driving load of the motor 14 in the inversion region, and more specifically, it can be detected by a pulse signal from the motor 14 not changing for a predetermined time or more. When a foreign object is caught in the reversal region, a drive reversal signal (opening direction driving signal) is output from the control unit U to the motor 14, and the window 10 is automatically reversed by a predetermined amount (for example, 200 mm) in the opening direction. Will be.
[0021]
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, in the inversion region, when the foreign object pinching indicated by the symbol I in FIG. 2 is detected, there is no pulse signal from the state in which the pulse signal from the motor 14 has existed (changed) until then. It changes to a (no change) state. That is, the pulse signal does not exist because the rotation of the motor 14 is forcibly stopped by the foreign object being caught. At time t3 when the absence of the pulse signal continues for a predetermined time, an opening direction drive signal is output to the motor 14 and the window 10 is automatically reversed. Will be generated again. When the driving of the window 10 in the opening direction proceeds, the limit switch 20 is changed from OFF to ON, and then the motor 14 is stopped at the position where the predetermined amount of the window 10 is driven in the opening direction.
[0022]
Here, the drive position of the motor 14 can be known by counting (monitoring) the number of pulses generated from the motor 14. Due to the step-out of the motor 14, the deviation in the correspondence between the number of count pulses and the opening / closing position of the window 10 indicates that the operating state change position of the limit switch 20 (indicated by the symbol M in FIG. It is corrected by adjusting the position.
[0023]
By accurately matching the mounting position of the limit switch 20 with the fully closed position (full closed line L1 or boundary line L2) of the window 10, the operating state change position of the limit switch 20 and the fully closed position of the window 10 are used as a reference. Thus, the absolute positional relationship is correctly associated. In consideration of the assembly error of the window 10 and the mounting position error of the limit switch 20, the initial setting of the lines L1 and L2, that is, the initial setting of the non-inversion area and the inversion area is performed as follows.
[0024]
First, a jig G as a substitute for the foreign object I as shown in FIGS. 10 to 12 is used for initial setting. This jig G has a fitting groove 31 fitted to the upper end of the window 10, and the window 10 is raised in a state where the fitting groove 31 is fitted to the upper end edge of the window 10 without rattling. If it does, it will be in the state where the jig | tool G was pinched | interposed by the window 10 (refer FIG. 2, FIG. 12). In FIG. 12, reference numeral 32 denotes a window sash, and 33 denotes a weather strip. Further, the jig G is formed of a synthetic resin or the like so that it is not easily deformed by a force of the degree to which the window 10 is sandwiched, and on the upper surface facing the weather strip 33 so as not to be damaged. There are no sharp edges.
[0025]
In a state where 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 region to be set (the embodiment). (4mm). 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 the distance between the operating state change position M of the limit switch 20 and the boundary line L2. This corresponds to the deviation (length). Accordingly, it is possible to accurately know the length from the point in time when the change of the operating state of the limit switch 20 is detected to the boundary line L2 or the fully closed line L1 by counting the number of output pulses of the motor 14. As described above, the inversion area is initially set by calculating and storing the number of output pulses from the motor 14 between t1 and t2, or between t3 and t4.
[0026]
Next, the contents of control by the control unit U will be described with reference to FIG. 13 and the following. In the following description, Q is a step, the symbol Y in the figure means YES, and N means NO. . The control contents described below roughly include initial setting of the inversion area, window opening / closing control, and failure determination control of the limit switch 20. The opening / closing drive of the window 10 can be performed within a predetermined time (for example, 40 seconds) after the ignition switch is turned off, that is, within the OFF timer setting time, other than when the ignition switch 35 is turned on.
[0027]
Description of FIG.
FIG. 13 shows control for identifying whether to perform initialization control of the inversion area or to perform opening / closing control of the window 10. That is, when it is determined that the ignition switch 35 is ON in Q1, the flag is reset to 0 to indicate that the ignition switch 35 is ON in Q2, and then the inversion area is initialized in Q3. It is determined whether or not a predetermined operation meaning the above command has been performed. In the embodiment, the predetermined operation is set to perform an opening operation (auto-up operation) and a closing operation (auto-down operation) of the open / close switch 22 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 performed three times continuously. When the predetermined operation is performed, that is, when the determination of Q3 is YES, inversion control of the inversion area is controlled in Q4 as described later.
[0028]
If the determination in Q1 is NO, it is determined in Q5 whether or not it is within a predetermined time after the ignition switch 35 is turned off, that is, whether or not it is within an OFF timer setting time that can open and close the window 10. Is done. 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. When the determination in Q3 is NO, the process proceeds to Q7. If NO in Q5, the process ends as it is.
[0029]
Description of FIG.
FIG. 14 shows details of Q7 in FIG. In the control of FIG. 14, basically, when the ignition switch 35 is ON, automatic reversal by foreign object pinching is performed during auto-up, and automatic reversal by foreign object pinching is not performed during manual up. In addition, within an OFF timer setting time which is within a predetermined time after the ignition switch 35 is turned off, automatic reversal by foreign object pinching is performed both in the auto-up and the manual up.
[0030]
Based on the above, it is determined whether or not a failure affecting the opening / closing control of the window 20 (in the embodiment, a failure of the limit switch 20) is detected in Q11. In Q12, it is determined whether or not an auto-up command has been issued. If YES in Q12, it is determined in Q13 whether or not a failure has been detected again. If NO in Q13, it is determined in Q14 whether the region is an inversion region. If YES in Q14, it is determined in Q15 whether or not foreign object pinching has been detected. If YES in Q15, the window 10 is automatically reversed in the opening direction by a predetermined amount (for example, 200 mm) in Q16.
[0031]
If the determination in Q12 is NO, it is determined whether there is a manual up command in Q17). If YES in Q17, it is determined in Q18 whether the flag is 1. If YES in Q18, this means that the ignition switch 35 has been turned off within a predetermined time. At this time, the process proceeds to Q14 (control with automatic reversal due to foreign object pinching during manual up command). When NO is determined in Q17, NO is determined in Q18, or NO is determined in Q14, the process proceeds to Q19, and the window 10 is opened / closed based on the operation of the opening / closing switch. No inversion is assumed.
[0032]
If YES in Q11, the alarm device 36 is actuated in Q20 and the process returns to Q11. If YES in Q13, the alarm device 36 is activated in Q22 after the window 10 is automatically reversed by a predetermined amount in Q21.
[0033]
Description of FIG.
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 inversion area is initially set based on the pulse count number between t1 and t2 in FIG.
[0034]
First, when it is determined at Q31 that an auto-up command has been issued, the window 10 is automatically raised at Q32, and then at Q33, it is determined whether or not the limit switch 20 has been changed to the OFF state. When the determination in Q33 is YES (time t1 in FIG. 9), the number of pulses from the motor 14 is counted in Q34. In Q35, it is determined whether or not the pulse count is larger than a predetermined value (for example, equivalent to a length larger than the size of the non-inverted region in the 10 cm closing direction driving of the window 10). If the determination in Q35 is NO, it is determined in Q36 whether foreign object pinching has been detected. Initially, NO is determined in Q36, and the process returns to Q34. However, as the window 10 is raised, the jig G as a dummy foreign object is eventually detected, so YES is determined in Q36.
[0035]
If YES in Q36 (time t3 in FIG. 9), the number of pulses counted between t1 and t2 is stored in Q37 (from the operation change position M of the limit switch 20 to the boundary line L2). Memory of the number of pulses). 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 for notifying that the initial setting of the inversion area has been performed by automatically inverting the window 10 in the opening direction, that is, the storage in Q37 has been performed. It is also used for removing the jig G.
[0036]
If the determination in Q33 is NO, it is determined in Q40 whether or not foreign object pinching has been detected. If the determination in Q40 is NO, the process returns to Q33. Further, when the determination in Q40 is YES, since the initial setting of the inversion area is not normally performed, the process proceeds to Q41 and the driving of the window 10 is stopped. If the determination in Q35 is YES, a failure of the limit switch 20 is considered. In this case, after the number of pulses counted in Q42 is cleared to 0, the process proceeds to Q41.
[0037]
Description of FIG.
FIG. 16 shows details of Q4 in FIG. 13, which is an embodiment different from FIG. In FIG. 16, the inversion area is initially set using the jig G, but the inversion area is initially set based on the pulse count number between t3 and t4 in FIG.
[0038]
First, Q51, Q52, Q53, and Q61 correspond to Q31, Q32, Q33, and Q40 in FIG. If it is confirmed by Q53 that the limit switch 20 has been turned OFF, it is determined at Q54 whether or not the jig G has been caught. When the determination in Q54 is YES (time t3 in FIG. 9), after the window 10 is automatically reversed in the opening direction in Q55, the number of pulses from the motor 14 is counted in Q56. It is determined whether or not the number of pulses counted in Q57 is larger than a predetermined value (corresponding to Q35 in FIG. 15). When the determination in Q57 is NO, the limit switch 20 is changed to the ON state in Q58. Is determined. If NO in Q59, the process returns to Q56.
[0039]
If YES in Q58, the number of pulses counted between t3 and t4 is stored in Q59 (corresponding to Q37 in FIG. 15), and then the counted number of pulses is cleared to zero. The alarm device 36 is activated to notify that the initial setting of the reversal region has been performed. When the determination in Q57 is YES, the limit switch 20 is out of order and cannot be initialized. In this case, the process proceeds to Q62 and the driving of the window 10 is stopped.
[0040]
Description of FIGS. 17 and 18
FIGS. 17 and 18 detect the failure of the limit switch 20, and show details of failure detection of Q11 and Q13 of FIG. However, the failure in Q11 and Q13 is not limited to the failure of the limit switch 20.
[0041]
The failure detection of the limit switch 20 includes an ON failure stuck in the ON state and an OFF failure stuck in the OFF state. In FIG. 17 and FIG. 18, both the failure judgments are cleared (failure judgment is withdrawn). Control to do is also included. The ON 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 ON state (the predetermined amount is larger than the total drive amount from the fully closed to fully opened window 10). It is a small value and a value larger than the window drive amount from the limit switch operating state change position M and the window fully open position, and is equivalent to 50 cm in the embodiment).
[0042]
An OFF 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 OFF state (the predetermined amount is the operating state change position M of the limit switch 20 and the window fully closed position Is set to a value larger than the length up to 10 cm in the embodiment). The failure determination is cleared when the operating state of the limit switch 20 changes from ON to OFF or from OFF to ON.
[0043]
On the premise of the above, first, in Q71 of FIG. 17, it is determined whether or not the window 10 is in the up-drive state in which it is driven in the closing direction. If YES in Q71, it is determined in Q72 whether the limit switch 20 is currently in the ON state. If YES in Q72, after the number of pulses from the motor 14 is counted in Q73, it is determined in Q74 whether the counted number of pulses is larger than a predetermined value (equivalent to 50 cm). . If the determination in Q74 is YES, it is determined in Q75 that the limit switch 20 is in the ON state when it is fixed, and then the counted number of pulses is cleared to 0 in Q76.
[0044]
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 YES in Q77, the process proceeds to Q76 after the ON failure determination is cleared in Q78. If NO in Q77, the limit switch 20 is OFF. In this case, after the number of pulses from the motor 14 is counted in Q79, the counted number of pulses is a predetermined value in Q80. It is determined whether it is larger than (equivalent to 10 cm). If the determination in Q80 is YES, it is determined in Q81 that the limit switch 20 is in the OFF state and is locked off. If NO in the determination of Q74 or NO in the determination of Q80, the process is terminated without performing failure determination and failure determination clear.
[0045]
When the determination in Q81 is NO, the process proceeds to Q91 in FIG. 18. This FIG. 18 is for when the window 10 is driven downward, that is, in the opening direction, and corresponds to FIG. Yes. First, at Q91 in FIG. 18, it is determined whether or not the window 10 is in the down drive state in which the window 10 is driven in the opening direction. If YES in Q91, it is determined in Q92 whether the limit switch 20 is currently in the OFF state. If YES in Q92, after the number of pulses from the motor 14 is counted in Q93, it is determined in Q94 whether the counted number of pulses is larger than a predetermined value (equivalent to 10 cm). . If the determination in Q94 is YES, it is determined in Q95 that the limit switch 20 is in the OFF state and is in an OFF failure state, and then the counted number of pulses is cleared to 0 in Q96.
[0046]
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 YES in Q97, the process proceeds to Q96 after clearing the OFF failure determination in Q98. If NO in Q97, 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, the counted number of pulses is a predetermined value in Q100. It is determined whether it is greater than (equivalent to 50 cm). If the determination in Q100 is YES, it is determined in Q101 that the limit switch 20 is in an ON failure that is stuck in the ON state. When the determination at Q91 is NO, the determination at Q94 is NO, or the determination at Q100 is NO, the process ends without performing failure determination and failure determination clear.
[0047]
Although the embodiment has been described above, the present invention is not limited to this, and includes, for example, the following cases. The jig G can be of a type that is detachably fixed to the window sash 32 without being fitted to the window 10. Automatic reversal by foreign object pinching is not limited to the driver's seat window, but can be applied to other windows as well.
