The following embodiments are for facilitating the understanding of the present invention, but do not limit the present invention. That is, the present invention can be modified and improved without departing from the spirit thereof, and it goes without saying that the present invention includes an equivalent thereof.
Further, in the following, a power window device for a vehicle (hereinafter, power window device 1) will be described as a specific example of the opening / closing member control device.

<Outline and basic configuration of power window device>
The outline and the basic configuration of the power window device 1 will be described. The power window device 1 moves (moves up and down) the window glass 2 constituting the window of the vehicle by power. The hardware configuration of the power window device 1 is the same as that of a normal power window device. Specifically, as shown in FIG. 1, the power window device 1 has a window glass 2, a drive device 3, and a glass run 4.

The window glass 2 corresponds to an opening / closing member that can be moved to open / close the opening H of the door D. More specifically, the window glass 2 receives the driving force of the driving device 3 and moves between the closed position and the open position along a rail (not shown) installed inside the door D. The closed position is a position where the window glass 2 closes the opening H of the door D in the moving range of the window glass 2, and is a position where the upper end of the window glass 2 comes into contact with the connecting portion 4b of the glass run 4 described later. The open position is a position where the window glass 2 opens the opening H of the door D in the moving range of the window glass 2, and a position where the upper end of the window glass 2 is lower than the lower end of the opening H.

In the present embodiment, the window glass 2 can be moved upward and downward like the window glass of a normal power window device. Here, among the directions when the window glass 2 moves, the downward direction (in other words, the direction in which the opening H is opened) corresponds to the first direction, and the upward direction (in other words, the direction in which the opening H is closed) is the second direction. Corresponds to the orientation.

The drive device 3 is a device that operates to move (up and down) the window glass 2, and is composed of a known elevating mechanism in the present embodiment, and more specifically, it is configured by an X-arm mechanism. As shown in FIG. 1, the drive device 3 includes a motor M as a drive source, a gear 11 directly connected to the motor M, an elevating arm 12 having a fan-shaped gear 12a that meshes with the gear 11, and an elevating arm. A driven arm 13 pivotally supported in an X-shaped crossing with respect to 12, a fixed channel 14 provided on the door D so as to engage with the lower end of the driven arm 13, an elevating arm 12 and a driven arm. It has a glass side channel 15 provided at the bottom of the window glass 2 so as to engage with the upper end of each of the 13. The motor M rotates to move the window glass 2, and in the present embodiment, the motor M includes a reduction mechanism Mx fixed to the door D. The motor M according to the present embodiment can rotate in both the forward direction and the reverse direction.

When the motor M rotates, its rotational force is transmitted to the elevating arm 12 and the driven arm 13 via the gear 11 and the fan-shaped gear 12a. As a result, both the elevating arm 12 and the driven arm 13 swing. At this time, the lower end portion of the driven arm 13 is guided by the fixed channel 14 to regulate the moving direction thereof, and similarly, the upper end portions of the elevating arm 12 and the driven arm 13 are connected to the glass side channel 15. By being guided, the direction of movement is regulated. As a result, the elevating arm 12 and the driven arm 13 function as an X-link, and move up and down with the window glass 2 attached to the elevating arm 12 and the driven arm 13 via the glass side channel 15. Become. By the above procedure, the drive device 3 moves (moves up and down) the window glass 2.

The drive device 3 is not limited to the X-arm type elevating mechanism, and can be used without limitation as long as the window glass 2 is opened and closed by using the motor M. For example, an endless wire or belt attached to the window glass 2 and a plurality of pulleys for driving the wire or belt are provided, and the rotation of the motor M is transmitted to the wire or belt by each pulley, and the wire or belt is transmitted. May be a mechanism for moving (moving up and down) the window glass 2 by operating.

The glass run 4 corresponds to an elastic contact member, and is provided at the upper end portion (strictly speaking, the upper end edge portion) of the opening H of the door D as shown in FIG. The glass run 4 is made of a rubber member having a substantially inverted U-shaped cross section, and has a pair of lip portions 4a and a connecting portion 4b as shown in FIG. The pair of lip portions 4a are arranged so as to be adjacent to each other with the window glass 2 interposed therebetween. That is, one of the pair of lip portions 4a is located inside the window glass 2 (inside the vehicle), and the other is located outside the window glass 2 (outside the vehicle). Each lip portion 4a extends downward, and its tip portion (hereinafter, lip tip portion 4c) is folded back in a J shape. The connecting portion 4b connects the upper end portions of the pair of lip portions 4a to each other, and is integrally molded with each of the pair of connecting portions 4b in the present embodiment.

The glass run 4 configured as described above is in contact with the window glass 2 on the position side where the window glass 2 closes the opening H of the door D (that is, the upper end edge side of the opening H) in the moving range of the window glass 2. More specifically, when the window glass 2 is located below the glass run 4, the glass run 4 is in a state where the lip tips 4c of the pair of connecting portions 4b are in contact with each other (in FIG. 2, each lip tip). The part 4c is in the position of the broken line). When the window glass 2 rises from such a state and approaches the glass run 4, the upper end portion of the window glass 2 eventually enters the gap between the lip portions 4a while pushing away the lip tip portion 4c of each lip portion 4a. As a result, the glass run 4 comes into contact with the window glass 2 at each lip portion 4a with the upper end portion of the window glass 2 sandwiched between the lip portions 4a.

After that, when the window glass 2 is further raised, the glass run 4 is deformed so that the lip tip portions 4c of the pair of lip portions 4a are gradually separated from each other as shown in FIG. That is, each lip portion 4a is displaced by moving the window glass 2 while the glass run 4 is in contact with the window glass 2. As a result, the contact points of the lip portions 4a with the window glass 2 are changed (shifted).
Then, as shown in FIG. 2, when the glass run 4 reaches a position where the upper end of the window glass 2 comes into contact with the lower surface of the connecting portion 4b, the opening H of the door D is closed by the window glass 2 at that time. become.

Next, the control mechanism of the power window device 1 and related devices will be described with reference to FIG. In the power window device 1 according to the present embodiment, when the occupant of the vehicle operates the operation switch 5 provided on the door D, the motor M rotates according to the operation content, and the window glass 2 is desired accordingly. Move to position. As a configuration for realizing such control, the power window device 1 includes a control device 20 as shown in FIG. The control device 20 controls the drive device 3, and more specifically, controls the motor M of the drive device 3.

The control device 20 includes a controller unit 21 and a motor drive circuit 22. The controller unit 21 is composed of, for example, an in-vehicle ECU (Electronic Control Unit), and is activated by the electric power supplied from the battery B. Further, the controller unit 21 has a built-in timer 23. The motor drive circuit 22 constitutes a power supply circuit from the battery B to the motor M, and is a relay for switching the energization state between the battery B and the motor M and a relay for switching the direction of the current flowing through the motor M. It is equipped with. Then, the controller unit 21 switches the start / stop of the motor M and the rotation direction of the motor M by controlling the relay in the motor drive circuit 22 on and off.

The operation switch 5 is a swing type switch that can be operated in two stages, and has an open switch, a closed switch, and an auto switch. When the operation switch 5 is operated, a command signal is output to the controller unit 21. Specifically, when one end side of the operation switch 5 is operated one step, the close switch is turned on, and a command signal for moving the window glass 2 upward (closed movement) only during the period when the operation switch 5 is operated is sent. It is output. Upon receiving the command signal, the controller unit 21 controls the motor M to continuously rotate in the forward direction during the reception period of the command signal. As a result, the window glass 2 moves upward while the operation switch 5 is operated.
Further, when the other end side of the operation switch 5 is operated one step, the open switch is turned on, and a command signal for moving the window glass 2 downward (open movement) is output only during the period when the operation switch 5 is operated. .. Upon receiving the command signal, the controller unit 21 controls the motor M to continuously rotate in the reverse direction during the reception period of the command signal. As a result, the window glass 2 moves downward while the operation switch 5 is being operated.

Further, when one end side of the operation switch 5 is operated in two steps, both the close switch and the auto switch are turned on, and a command signal for moving the window glass 2 until it reaches the closed position is output. Upon receiving the command signal, the controller unit 21 controls the motor M so that the window glass 2 continues to rotate in the forward direction until it reaches the closed position. As a result, the window glass 2 continues the automatic closing movement (that is, the operation of continuing to move upward even if the operation of the operation switch 5 is stopped) until the closed position, and stops when the closed position is reached.
Further, when the other end side of the operation switch 5 is operated in two steps, both the open switch and the auto switch are turned on, and a command signal for moving the window glass 2 until it reaches the open position is output. Upon receiving the command signal, the controller unit 21 controls the motor M so that the window glass 2 continues to rotate in the reverse direction until it reaches the open position. As a result, the window glass 2 continues the automatic open movement (that is, the operation of continuing to move downward even if the operation of the operation switch 5 is stopped) until the open position, and stops when the open position is reached.

In the present embodiment, when the window glass 2 automatically closes and moves, the position where the upper end of the window glass 2 starts to come into contact with the connecting portion 4b of the glass run 4 is set as the closed position, and the window glass 2 stops at such a position. The motor M is to be controlled in this way.

The controller unit 21 monitors the rotational state of the motor M during the control period of the motor M. Specifically, the Hall element 24 is attached to the motor M. The Hall element 24 corresponds to a rotation detector and outputs a pulse signal as a signal corresponding to the rotation state of the motor M. The pulse signal is output in synchronization with the rotation of the motor M, and is output for each predetermined movement amount of the window glass 2 or for each predetermined rotation angle of the motor M. The controller unit 21 receives the pulse signal output from the Hall element 24, and specifies the rotational state of the motor M based on the received pulse signal. Specifically, the controller unit 21 specifies the rotation speed of the motor M from the pulse signal reception interval (strictly speaking, the pulse edge interval), and the rotation of the motor M from the number of pulse signal receptions (counts). Specify the amount. Further, the controller unit 21 calculates the current position (position after movement) of the window glass 2 based on the count number of the pulse signal. Further, the controller unit 21 determines whether the motor M is rotating normally based on the presence or absence of reception of the pulse signal during the control period of the motor M.

Further, the controller unit 21 has a function of specifying the situation inside and outside the vehicle by receiving signals from various in-vehicle sensors. Specifically, as the equipment constituting the power window device 1, the temperature sensor 25 and the seat sensor 26 shown in FIG. 3 are provided in the vehicle. The temperature sensor 25 is a sensor that outputs a signal according to the temperature outside the vehicle (outside air temperature), and the controller unit 21 specifies the outside air temperature at that time by receiving the signal from the temperature sensor 25. It is configured to do.

The seat sensor 26 is a sensor for detecting that the occupant is seated on the seat (not shown), and continues to output a signal while the occupant is seated on the seat. The controller unit 21 recognizes that there is an occupant in the vehicle while receiving the signal from the seat sensor 26. The seat sensor 26 is composed of, for example, a weight sensor attached to the seat.

The control device 20 (strictly speaking, the controller unit 21) configured as described above is activated by the power supplied from the battery B and operates in the normal mode while the ignition switch (not shown) is on. .. When the operation switch 5 is operated in the normal mode, the controller unit 21 controls the motor M as described above to move the window glass 2.

On the other hand, while the ignition switch is off, the control device 20 enters the sleep mode in which devices other than the timer 23 are inactive. Further, during the sleep mode, the elapsed time from the reference time is monitored by the timer 23, and in the present embodiment, when the elapsed time reaches a predetermined time (for example, 1 hour), the controller shifts to the wake-up mode. The unit 21 is supposed to be activated temporarily. The reference time is the time when the previous wake-up mode ended.

During the wake-up mode, the controller unit 21 executes a predetermined control process according to the situation inside and outside the vehicle. Specifically, when the outside air temperature is equal to or lower than a predetermined temperature (for example, 0 ° C.) during a period when there are no occupants in the vehicle, the controller unit 21 triggers the window glass 2 when a predetermined condition is satisfied. A control process (hereinafter referred to as anti-freezing process) for preventing freezing of the glass is carried out. Here, the freezing of the window glass 2 means that the window glass 2 freezes in a state of being in contact with the glass run 4, which makes it difficult to move. The antifreezing treatment will be described in detail in the next section.

<About anti-freezing treatment>
The freeze prevention process by the controller unit 21 will be described with reference to FIGS. 4 to 6.
As described above, the anti-freezing process is performed when the window glass 2 is stopped at a position where the window glass 2 is in contact with the glass run 4 and a predetermined condition is satisfied during the period when the controller unit 21 is in the wake-up mode. Implemented as a trigger. More specifically, in the wake-up mode, the outside air temperature is a predetermined temperature (0 ° C. in this embodiment) or less for a predetermined time (this) while the window glass 2 is stopped at a position in contact with the glass run 4. In the embodiment, if the temperature is maintained for 3 hours or more, the antifreeze treatment is carried out.

The threshold value of the outside air temperature set as the implementation condition of the antifreezing treatment and the time during which the outside air temperature is maintained at the threshold value are not particularly limited and can be arbitrarily determined.

In the antifreezing process, the controller unit 21 controls the motor M so that the window glass 2 moves while being in contact with the glass run 4 and the contact portion of the glass run 4 with the window glass 2 changes. More precisely, in the antifreeze treatment, the window glass 2 in the closed position remains in contact with each of the connecting portion 4b of the glass run 4 and the pair of lip portions 4a (specifically, the lip tip portion 4c). The motor M is controlled so as to move and change the contact portion of each lip portion 4a with the window glass 2.

By moving the window glass 2 so that the contact portion changes (shifts) as described above, it is possible to prevent the window glass 2 from freezing at the contact portion. As a result, when the occupant subsequently gets into the vehicle and tries to open the window glass 2, the window glass 2 opens smoothly.

Hereinafter, the flow of the antifreeze treatment will be described, and each step of the antifreeze treatment will be described in detail. In carrying out the freeze prevention process, the mode of the controller unit 21 shifts from the sleep mode to the wakeup mode. In the wake-up mode, the controller unit 21 receives output signals from each of the temperature sensor 25 and the seat sensor 26, and specifies the outside air temperature at that time and the presence or absence of an occupant in the vehicle. Further, the controller unit 21 specifies the position of the window glass 2 at that time. Specifically, the controller unit 21 stores the position of the window glass 2 specified when the motor M is rotated immediately before (strictly speaking, at the end of rotation) in the memory, and reads the position from the memory. Therefore, it is specified as the position of the window glass 2 at that time.

After the above pre-operation, the controller unit 21 starts the antifreezing process, and carries out each step of the antifreezing process according to the flow shown in FIG. 4. In the anti-freezing process, first, it is determined whether or not there is an occupant in the vehicle (S001). When it is determined in step S001 that there is no occupant in the vehicle, the controller unit 21 next determines whether or not the window glass 2 is in the closed position (S002). If it is determined in step S002 that the window glass 2 is in the closed position, the controller unit 21 proceeds to step S003 and subsequent steps.
On the other hand, if it is determined in step S001 that there is an occupant in the vehicle, or if it is determined in step S002 that the window glass 2 is in a position other than the closed position, the antifreezing process ends at that point.

When there are no occupants in the vehicle and the window glass 2 is in the closed position, the controller unit 21 further determines whether the specified outside air temperature is 0 ° C. or lower based on the output signal from the temperature sensor 25 ((). S003). When it is determined that the outside air temperature is 0 ° C. or lower, the controller unit 21 determines whether the outside air temperature is maintained at 0 ° C. or lower for 3 hours or more (S004). More specifically, the controller unit 21 stores the time of the timer 23 at that time when the determination in step S003 is performed. Then, the controller unit 21 confirms whether the determination result at each time is the result that "the outside air temperature is 0 ° C. or less" continuously for 3 hours or more. When it is determined that the outside air temperature is maintained at 0 ° C. or lower for 3 hours or more, the controller unit 21 proceeds to step 005 or later.
On the other hand, if it is determined in step S003 that the outside air temperature is not 0 ° C. or lower, or if it is determined in step S004 that the time for maintaining the outside air temperature at 0 ° C. or lower is less than 3 hours, the controller unit 21 Repeats steps S003 and S004.

When the outside air temperature is maintained at 0 ° C. or lower for 3 hours or more, the controller unit 21 moves while the window glass 2 is in contact with each lip portion 4a of the glass run 4, and the window of each lip portion 4a is moved. The motor M is controlled so that the contact point with the glass 2 changes. Specifically, the motor M is rotated in the forward direction so that the window glass 2 moves further upward (that is, in the second direction) from the closed position.

More specifically, the controller unit 21 controls the motor M so that the first rotation operation of rotating the motor M so that the window glass 2 moves upward from the closed position is performed intermittently a plurality of times (S005). In this embodiment, the first rotation operation is to be performed twice. When the first first rotation operation is performed, the window glass 2 rises slightly, and specifically, as shown in FIG. 5, the upper end portion of the window glass 2 rises to a position where it bites into the connecting portion 4b of the glass run 4. do. Along with this, the contact points of the lip portions 4a with the window glass 2 change (shift).

Immediately after the first first rotation operation is performed, the second first rotation operation is performed, and the window glass 2 has a glass run 4 at the upper end of the window glass 2 as shown in FIG. It rises to a position where it further bites into the connecting portion 4b of. Along with this, the contact points of the lip portions 4a with the window glass 2 are further changed (shifted).

As described above, in the present embodiment, the contact portion between the window glass 2 and the glass run 4 is intermittently changed by performing the first rotation operation intermittently a plurality of times. This makes it possible to effectively prevent a situation in which the window glass 2 is stuck in contact with the glass run 4 due to freezing or the like.
The number of times the first rotation operation is performed is not particularly limited, and can be set to any number of times.

After that, the controller unit 21 controls the motor M so that the second rotation operation of rotating the motor M so that the window glass 2 at the position shown in FIG. 6 moves downward (that is, in the first direction) is performed. (S006). The above-mentioned second rotation operation is an operation performed to confirm that the window glass 2 is not frozen, and by performing the second rotation operation, the window glass 2 is positioned before the first rotation operation is performed, that is, It returns to the closed position (the position shown in FIG. 2). In this way, the second rotation operation is performed with the window glass 2 in contact with the connecting portion 4b of the glass run 4. This makes it possible to confirm that the window glass 2 is not frozen while the opening H of the door D is closed by the window glass 2.

Here, while the motor M is performing the first rotation operation or the second rotation operation described above, the controller unit 21 receives the pulse signal from the Hall element 24, and the rotation state of the motor M (specifically, the rotation state of the motor M). The amount of rotation, rotation speed, etc.) is monitored. Then, the controller unit 21 determines whether or not the motor M has normally rotated in each rotation operation (S007). When it is determined that the motor M is not rotating normally, the controller unit 21 repeats steps S005 and S006 so that the window glass 2 moves while being in contact with the glass run 4 so that the contact portion changes. The motor M is controlled again. As a result, the contact portion between the window glass 2 and the glass run 4 can be reliably changed, and freezing of the window glass 2 can be accurately prevented.

If it is determined in step S007 that the motor M is rotating normally, the controller unit 21 returns to step S001 and repeats the above series of steps.
