Description

  The present invention relates to an opening / closing member control apparatus, and includes an opening / closing member control apparatus that includes a motor that rotates to move the opening / closing member toward a closed position, and that continues to supply power to the motor after the opening / closing member reaches the closed position. About.

  An open / close member control device that controls the movement of an open / close member that moves to open and close an opening provided in a vehicle is already known, and examples thereof include a power window device, a slide door device, and a sunroof device. Etc. Some opening / closing member control devices include a motor that rotates to move the opening / closing member toward the closed position, and continues to supply power to the motor even after the opening / closing member reaches the closed position. To do. For example, in the open / close member control device described in Patent Document 1, the duty ratio is set to 100% for supplying power to the drive motor for a predetermined time after the window glass as the open / close member reaches the fully closed position and the drive motor is locked. It is supposed to be performed under the conditions. With such a configuration, even if the drive motor is locked, the driving force acts in the closing direction of the window glass with a high output, so that the window glass is surely closed and closed.

JP 2005-54564 A

  By the way, after power supply to the drive motor is continued for a predetermined time after the drive motor is locked, an operating body such as a relay provided in the power supply circuit is provided to stop the power supply. Turn off. At this time, if the operating body is actuated for a while after the window glass reaches the closed position, the operating sound becomes conspicuous (conspicuous) for the vehicle occupant. On the other hand, in order to provide a more comfortable in-vehicle environment, it is necessary to make the above-described operation sound as inconspicuous as possible.

  Therefore, the present invention has been made in view of the above problems, and its purpose is to stop power supply thereafter in a configuration in which power supply to the motor is continued after the opening / closing member reaches the closed position. It is an object of the present invention to provide an opening / closing member control device capable of making an operation sound inconspicuous when operating an operating body.

  According to the opening / closing member control device of the present invention, the object is to adjust a motor that rotates to move the opening / closing member toward a closed position that closes an opening provided in the vehicle, and power supply to the motor. A control unit that switches the on / off of the operating body, and when the opening / closing member that moves toward the closed position reaches the closed position, the control unit The signal is output from a signal output unit that outputs a signal corresponding to the traveling state of the vehicle, and the operating body is turned on so that the power supply is continued for a time corresponding to the traveling state specified by the signal. This is solved by turning the operating body off after being held in place.

  According to the opening / closing member control apparatus of the present invention configured as described above, the duration time when the power supply to the motor is continued after the opening / closing member reaches the closed position is the vehicle running state at that time. It will change accordingly. If the duration is changed according to the running state of the vehicle, the timing at which the operating body is turned off in order to stop the power supply, in other words, the timing at which the operating sound of the operating body is generated is also the vehicle running state. It will change according to. Thereby, the generation timing of the operating sound is adjusted to an appropriate timing according to the traveling state of the vehicle at that time. As a result, it is possible to relatively reduce the magnitude of the operating sound felt by the vehicle occupant, thereby preventing the operating sound from being noticeable.

In the opening / closing member control apparatus, the control unit may receive the signal corresponding to the traveling speed of the vehicle from the signal output unit.
In the above configuration, the control unit receives a signal corresponding to the traveling speed of the vehicle from the signal output unit as a signal corresponding to the traveling state of the vehicle. With such a configuration, it is possible to relatively easily acquire information related to the running state of the vehicle, which is necessary when adjusting the generation timing of the operating sound.

In the above-described opening / closing member control device, when the opening / closing member moving toward the closed position reaches the closed position, the control unit determines that the traveling speed specified by the received signal is equal to or higher than a reference value. When the operating body is held in an on state so that the power supply is continued for a first time, the operating body is turned off, and the traveling speed specified by the received signal is the reference When the value is less than the value, the operating body may be held in an on state so that the power supply is continued for a second time shorter than the first time, and then the operating body is turned off.
In the above configuration, if the traveling speed of the vehicle is equal to or higher than the reference value, the time during which the power supply to the motor is continued after the opening / closing member reaches the closed position is made longer, and the timing for turning off the operating body accordingly is set. Will be delayed. In other words, when the vehicle is traveling at a relatively high speed, the operating sound of the operating body is erased by the traveling sound of the vehicle, etc. Even if the timing is delayed), the operating noise is less noticeable. On the other hand, if the traveling speed of the vehicle is less than the reference value, the power supply duration time is shortened, and the timing for turning off the operating body is advanced. In other words, if the interior of the vehicle is relatively quiet because the vehicle is stopped or running at a low speed, the operation noise will stand out if the generation timing of the operation noise is delayed. Shortening the operation sound (prompt the generation timing of the operation sound) to suppress the operation sound from standing out.

In the above-described opening / closing member control device, the control unit holds the operating body in an on state so that the power supply is continued only for the second time after the opening / closing member reaches the closed position. When the operating body is turned off, the power supply is resumed when the traveling speed specified by the signal received from the signal output unit after the second time elapses is equal to or higher than the reference value. The operating body may be turned on so as to move the opening / closing member in the same direction as when moving toward the closed position.
In the above configuration, when the duration of power supply to the motor after the opening / closing member reaches the closed position is set to a shorter time (second time), the duration is not sufficiently secured. become. In such a case, there is a possibility that the opening / closing member is not securely closed. On the other hand, according to the above configuration, after the second time has elapsed, when the traveling speed is equal to or higher than the reference value, the power supply is resumed, and the direction when the opening / closing member is moving toward the closed position is Move the opening and closing member in the same direction. As a result, even if the duration time is short, the power supply is resumed on condition that the traveling speed of the vehicle becomes equal to or higher than the reference value thereafter, so that the opening / closing member can be reliably closed. .

Further, in the above opening / closing member control device, the elastic member arranged at the edge of the opening opposes the front end of the opening / closing member while the opening / closing member moves toward the closed position, and When the member comes into contact with the tip when the member reaches the closed position, the control unit determines that the traveling speed specified by the signal received from the signal output unit after the second time has elapsed is the reference. When the opening and closing member is in the closed position, the power supply is resumed and the opening and closing member is moved in the same direction as when moving toward the closed position. Thus, the operating body may be turned on.
In the above configuration, when the duration of power supply to the motor after the opening / closing member reaches the closed position is set to a shorter time, the traveling speed thereafter becomes equal to or higher than the reference value, and at that time, the opening / closing member The power supply is resumed on the condition that is in the closed position. On the other hand, when the opening / closing member is in the closed position, the elastic member disposed at the edge of the opening is in contact with the tip of the opening / closing member. In such a configuration, when the duration time is short, the effect that the power supply is restarted according to the traveling speed of the vehicle and the closing of the opening / closing member is reliably performed becomes more significant. More specifically, when the duration time is short, the degree of adhesion between the elastic member and the opening / closing member is relatively small. In such a case, abnormal noise (wind noise) is generated by the passage of wind through the gap between the elastic member and the opening / closing member. On the other hand, in said structure, since electric power supply is restarted on a fixed condition and the opening-and-closing member is reliably closed, it can suppress said abnormal noise generating.

In the above opening / closing member control device, the operating body may be a relay.
When the operating body is composed of a relay as described above, the effect of the present invention becomes more effective. That is, in the above configuration, the relay performs an off operation when power supply to the motor is stopped. At this time, an operating noise of the relay is generated, but according to the present invention, it is possible to prevent the operating noise from being emphasized.

  According to the opening / closing member control device of the present invention, when the opening / closing member continues to supply power to the motor after reaching the closed position and then the operating body is operated to stop the power supply, the operating sound is emphasized. It is possible not to stand.

It is a figure which shows the mechanical structure of the opening / closing member control apparatus which concerns on one Embodiment of this invention. It is a figure which shows the control system of the opening / closing member control apparatus which concerns on one Embodiment of this invention. FIGS. 3A and 3B are explanatory diagrams relating to control of power supply to the motor. It is a figure which shows the electric power supply control flow after close position arrival.

  Hereinafter, one embodiment (this embodiment) of the present invention will be described with reference to FIGS. FIG. 1 is a diagram illustrating a mechanical configuration of the opening / closing member control apparatus according to the present embodiment. FIG. 2 is a diagram illustrating a control system of the opening / closing member control apparatus according to the present embodiment. FIGS. 3A and 3B are explanatory diagrams relating to control of power supply to the motor. FIG. 4 is a diagram showing a power supply control flow (denoted as a lock energization control flow in the drawing) after reaching the closed position.

  Hereinafter, the power window device S will be described as an example of the opening / closing member control device. That is, in the following, the window glass 2 attached so as to be movable up and down with respect to the door 1 of the vehicle will be taken as an example of the opening / closing member, and the opening / closing member control device for controlling the moving operation (elevating operation) of the window glass 2. Will be described.

  The power window apparatus S according to the present embodiment moves the window glass 2 between a closed position where the opening 1a provided in the door 1 of the vehicle is fully closed and an open position where the opening 1a is fully opened. . More specifically, the window glass 2 is configured to be movable between a closed position and an open position along a rail (not shown). When the window glass 2 moves toward the closed position and reaches the closed position, the window glass 2 comes into contact with the weather strip 1b at its upper end (tip). The weather strip 1b corresponds to the elastic member of the present invention, and is provided on a window frame that is an edge of the opening 1a. Further, the portion of the weather strip 1b arranged on the upper end side of the window frame is opposed to the upper end portion of the window glass 2 while the window glass 2 moves toward the closed position, and the window glass 2 is closed. When it reaches the position, it comes into contact with the upper end of the window glass 2. That is, the closed position corresponds to a locked position where the upward movement of the window glass 2 is locked (regulated) by the weather strip 1b.

  In the present embodiment, the upward movement of the window glass 2 is continued for a predetermined time after the window glass 2 reaches the closed position. This is because the upper end portion of the window glass 2 is bitten into the weather strip 1b and the window glass 2 is surely closed and closed.

  Next, the configuration of the power window device S according to the present embodiment will be described. As shown in FIGS. 1 and 2, the power window device S includes a motor 3 that rotates to move the window glass 2 up and down, a lifting mechanism 4 that lifts and lowers the window glass 2 using the rotational force of the motor 3, and a motor. The main component is a control mechanism 5 for controlling the rotation of the vehicle 3 and an operation switch 6 operated when a vehicle occupant changes the position of the window glass 2.

  The motor 3 rotates when electric power is supplied from a battery B mounted on the vehicle. More specifically, the motor 3 rotates normally when the window glass 2 is moved upward, and reverses when the window glass 2 is moved downward. In addition, a rotation detection device 7 is attached to the motor 3. The rotation detection device 7 includes, for example, a plurality of Hall elements, and outputs a pulse signal synchronized with the rotation of the motor 3. More specifically, each Hall element constituting the rotation detection device 7 outputs a pulse signal every time the motor 3 rotates by a predetermined angle. That is, the rotation detection device 7 outputs a pulse signal according to the rotation speed of the motor 3.

  As shown in FIG. 1, the elevating mechanism 4 includes a main driving pulley 4a connected to the output shaft of the motor 3, two driven pulleys 4b and 4c, and an endless bridge spanning the three pulleys 4a, 4b and 4c. 4d. Further, a portion of the wire 4 d located between the driven pulleys 4 b and 4 c is hooked to a hooking portion 2 a provided on the window glass 2. In the elevating mechanism 4 configured as described above, when the main pulley 4a is rotated by the rotation of the motor 3, the wire 4d rotates endlessly along with the driven pulleys 4b and 4c. Then, the window glass 2 moves up and down in conjunction with the endless rotation of the wire 4d. In addition, the raising / lowering mechanism 4 is not restricted to what was comprised as mentioned above, As long as the window glass 2 is moved up and down using the rotational force of the motor 3, other mechanisms (for example, X arm type | formula) Regulator).

  The control mechanism 5 corresponds to a control unit of the present invention, and includes a controller 10 and a drive circuit 11 as shown in FIG. The controller 10 is constituted by a microcomputer with a built-in CPU, and is activated when power is supplied from the battery B. The devices constituting the controller 10 are not limited to microcomputers, and may be logic ICs, DSPs, gate arrays, transistors, and the like. The drive circuit 11 is an electric circuit for switching the presence / absence of power supply from the battery B to the motor 3 and the polarity (motor rotation direction) at the time of power supply. The configuration of the drive circuit 11 will be outlined. As shown in FIG. 2, two relays 12 and a field effect transistor 13 are incorporated in the drive circuit 11. The relay 12 is an operating body of the present invention, and is turned on / off to adjust the power supply to the motor 3. Note that one relay 12 is provided for each of the forward rotation and the reverse rotation of the motor 3 (two in total).

  The operation switch 6 outputs an operation signal related to the opening and closing of the window glass 2, and in this embodiment, the operation switch 6 is configured by a swing type switch or the like that can be operated in two steps, and has an open switch, a close switch, and an auto switch. ing. More specifically, when one end of the operation switch 6 is operated in one step, the closing switch is turned on, and a signal for normally closing the window glass 2 (to move upward only during the switch operation). Is output to the controller 10 as an operation signal. When one end of the operation switch 6 is operated in two stages, the close switch and the auto switch are turned on, and a signal for automatically moving the window glass 2 (a signal for continuing the upward movement to the closed position) is an operation signal. Is output to the controller 10. On the other hand, when the other end side of the operation switch 6 is operated in one step, the open switch is turned on, and a signal for moving the window glass 2 normally open (a signal for moving downward only while the switch operation is performed). The operation signal is output to the controller 10. When the other end side of the operation switch 6 is operated in two steps, the opening switch and the auto switch are turned on, and a signal for automatically moving the window glass 2 (a signal for continuing the downward movement to the open position) is operated. It is output to the controller 10 as a signal.

  The basic operation of the power window device S configured as described above will be described. When the operation switch 6 is operated, an operation signal corresponding to the operation content is output from the operation switch 6. Here, assuming that a signal for normally closing and moving the window glass 2 (hereinafter referred to as a normal closing signal) is output as the operation signal, the controller 10 receives the normal closing signal output from the operation switch 6. Then, the drive circuit 11 is controlled based on the normal close signal. Specifically, the controller 10 turns on the forward relay 12 of the two relays 12 and outputs a voltage signal as a control signal toward the gate terminal of the field effect transistor 13. As a result, a voltage is applied between the gate terminal and the source terminal of the field effect transistor 13, the field effect transistor 13 is turned on, and a current circuit for forward rotation of the motor is formed. As a result, while the operation switch 6 is being operated, the drive current flows through the current circuit (that is, the forward rotation power is supplied), and the motor 3 is rotated forward. Then, when the elevating mechanism 4 is operated in conjunction with the normal rotation of the motor 3, the window glass 2 moves upward by a distance corresponding to the operation time of the operation switch 6 toward the closed position.

  On the other hand, when a signal for automatically closing and moving the window glass 2 (hereinafter referred to as an auto close signal) is output as an operation signal, the control output from the controller 10 to the drive circuit 11 is latched. As a result, the window glass 2 continues to move upward toward the closed position.

  By the way, the control mechanism 5 (specifically, the controller 10) described above receives the pulse signal output from the rotation detection device 7, and detects the current position of the window glass 2 based on the pulse signal. Further, the control mechanism 5 (specifically, the controller 10) switches on / off of the relay 12 in the drive circuit 11 in accordance with the detected current position of the window glass 2. Thereby, the magnitude | size of the electric power supplied to the motor 3 comes to be adjusted. More specifically, the controller 10 controls the magnitude of the supplied power using a PWM (Pulse Width Modulation) method. That is, in the present embodiment, the duty ratio is adjusted in order to adjust the power supplied to the motor 3.

  The adjustment of the power supplied to the motor 3 will be described in detail with reference to FIGS. In the figure, a change in supply power (strictly speaking, supply voltage) in a case where the window glass 2 positioned at the open position is automatically closed toward the closed position is illustrated. Hereinafter, the case illustrated in FIGS. 3A and 3B will be described as an example.

  While the window glass 2 is automatically closed, the controller 10 periodically detects the current position of the window glass 2. More specifically, the controller 10 detects the current position of the window glass 2 based on the pulse count value counted up from the time when the window glass 2 was positioned at the origin position with the open position as the reference position (origin position). To do. The pulse count value is a value when the controller 10 counts the rising portion or the falling portion (pulse edge) of the pulse signal received from the rotation detection device 7.

  And the controller 10 detects the present position of the window glass 2 with the magnitude | size of a pulse count value. Specifically, the pulse count value is set to 0 at the open position, and the pulse count value is set to 1 each time the controller 10 receives a pulse signal while the window glass 2 is moving toward the closed position. Increment. On the other hand, a pulse count value corresponding to the position of the window glass 2 is stored in a memory (not shown) provided in the controller 10 as a storage device. Here, the pulse count value corresponding to the open position is set to Na (= 0), and the pulse count value corresponding to the closed position is set to Nb. Then, the controller 10 reads the correspondence between the pulse count value and the position of the window glass 2 from the memory, and detects the current position of the window glass 2 with reference to the correspondence.

  On the other hand, the controller 10 adjusts the power supplied to the motor 3 according to the detection result while detecting the current position of the window glass 2 by the above procedure. More specifically, as shown in FIGS. 3A and 3B, the window glass 2 is moved upward from the fully open position until reaching a predetermined position (hereinafter referred to as an acceleration end position). In other words, when the pulse count value is larger than Na and smaller than Ns (pulse count value corresponding to the acceleration end position), the controller 10 supplies power to the motor 3 so that the duty ratio increases in proportion to time. Control the supply. During this time, the window glass 2 moves upward toward the closed position while accelerating.

  Further, as shown in FIGS. 3A and 3B, the window glass 2 reaches a position slightly higher than the position after reaching the acceleration end position (hereinafter referred to as a primary constant speed end position). In other words, when the pulse count value is smaller than Ns to Nt (pulse count value corresponding to the primary constant speed end position), the controller 10 keeps the duty ratio at 100 so that the duty ratio is maintained at 100. Control the power supply to. During this time, the window glass 2 moves upward while maintaining a predetermined speed Vm.

  Further, as shown in FIGS. 3A and 3B, the window glass 2 reaches a position slightly higher than the same position after reaching the primary constant speed end position (hereinafter referred to as a deceleration end position). In other words, when the pulse count value is smaller than Nt to Nu (pulse count value corresponding to the deceleration end position), the controller 10 sends the motor 3 to the motor 3 so that the duty ratio decreases in proportion to time. To control the power supply. During this time, the window glass 2 moves upward while decelerating.

  In addition, as shown in FIGS. 3A and 3B, the pulse count value is smaller than Nt to Nb from the time when the window glass 2 reaches the deceleration end position to the time when it reaches the closed position. At this time, the controller 10 controls the power supply to the motor 3 so that the duty ratio is maintained at 50. During this time, the window glass 2 moves upward while maintaining a speed Vn somewhat smaller than the speed Vm.

  Further, as shown in FIGS. 3A and 3B, when the window glass 2 reaches the closed position, the controller 10 continues to supply power to the motor 3 at a duty ratio 100 for a certain time thereafter. . The reason why the power supply to the motor 3 is continued after the window glass 2 reaches the closed position in this way is to reliably close the window glass 2 as described above. That is, immediately after the window glass 2 reaches the closed position, the window glass 2 and the weather strip 1b may not be sufficiently adhered. On the other hand, when the window glass 2 is closed, the upper end portion of the window glass 2 is bitten into the weather strip 1b. At this time, a relatively large force is required due to resistance from the weather strip 1b. For this reason, in the present embodiment, power is supplied to the motor 3 at a duty ratio 100 for a predetermined time after the window glass 2 reaches the closed position and the motor 3 is locked. Thereby, even if the motor 3 is locked, a driving force for moving the window glass 2 further upward with high output is applied. As a result, the window glass 2 is reliably closed.

  By the way, when the power supply to the motor 3 (hereinafter referred to as lock energization) is continued for a predetermined time after the motor is locked, the controller 10 turns off the relay 12 that is in the ON state during the predetermined time. To do. On the other hand, while the energization of the lock is being performed, while the upper end portion of the window glass 2 bites into the weather strip 1b, both of the rubbing sounds are generated, but the biting of the window glass 2 has converged. Later, the rubbing noise disappears. For this reason, when the relay 12 is turned off after the energization of the lock, the operation sound of the relay 12 becomes noticeable for the vehicle occupant.

  Therefore, in the present embodiment, the lock energization execution time (hereinafter referred to as lock energization time) is variable in order to suppress the operation noise of the relay 12 from being noticeable. Specifically, when the window glass 2 reaches the closed position, the controller 10 according to the present embodiment controls the lock energization time according to the traveling speed of the vehicle at that time. This configuration will be described in detail below.

  In the present embodiment, the controller 10 is connected so as to be communicable with the vehicle speed sensor 8 via an in-vehicle LAN (not shown). The vehicle speed sensor 8 corresponds to a signal output unit of the present invention, detects the traveling speed of the vehicle, and outputs a speed detection signal that is a signal corresponding to the detection result (traveling speed). Then, when the window glass 2 that is automatically closed moves to the closed position, the controller 10 receives a speed detection signal from the vehicle speed sensor 8. In addition, the controller 10 holds the relay 12 in an on state so that the power supply to the motor 3 is continued for a time corresponding to the traveling speed specified by the speed detection signal, and then turns off the relay 12. .

  The above content will be described in detail with reference to FIG. 4. When the controller 10 detects that the window glass 2 that has been automatically closed has reached the closed position (S <b> 001), the speed indicating the traveling speed at that time. A detection signal is received from the vehicle speed sensor 8 (S002). Thereafter, the controller 10 determines whether or not the traveling speed specified by the received speed detection signal is equal to or higher than a reference value (S003). Here, the reference value is a value set in advance as a value for determining the lock energization time. For example, the occupant recognizes the traveling sound when the vehicle travels at a traveling speed corresponding to the reference value. This is a value that can be obtained (in this embodiment, 6 km / h).

  Then, when the identified traveling speed is equal to or higher than the reference value, the controller 10 sets the lock energization time to the first time (the time indicated by the symbol t1 in FIG. 3A) (S004). Thereafter, the controller 10 energizes the lock for the first time t1 (in other words, holds the forward relay 12 in the ON state), and turns off the relay 12 after the first time t1 has elapsed (S005). , S006).

  On the other hand, when the identified travel speed is less than the reference value, the controller 10 sets the lock energization time to the second time (the time indicated by the symbol t2 in FIG. 3B) (S007). The second time t2 is shorter than the first time t1, and in the present embodiment, the first time t1 is 200 ms, whereas the second time t2 is 50 ms. However, each of the first time t1 and the second time t2 can be determined at any time on condition that the magnitude relationship between the two does not change.

  When the lock energization time is set to the second time t2, the controller 10 executes the lock energization for the second time t2 (in other words, holds the forward relay 12 in the ON state), and the second time After t2 has elapsed, the relay 12 is turned off (S008, S009).

  As described above, in the present embodiment, when the traveling speed of the vehicle at the time when the window glass 2 that has been automatically closed reaches the closed position, the lock energization time is increased, and accordingly, The timing to turn off the relay 12 is delayed. That is, when the vehicle is traveling at a relatively fast speed, the operation sound of the relay 12 is canceled out by the traveling sound of the vehicle. For this reason, even if the lock energization time is ensured for a long time (in other words, even when the timing of generation of the relay operation sound is delayed), the operation sound is difficult to stand out.

  On the other hand, when the traveling speed of the vehicle is less than the reference value, the lock energization time is shortened, and the timing for turning off the relay 12 is advanced accordingly. That is, when the interior of the vehicle is relatively quiet because the vehicle is stopped or traveling at a low speed, the operation noise becomes noticeable when the generation timing of the relay operation noise is delayed. For this reason, the above-mentioned lock energization time is shortened (in other words, the generation timing of the relay operation sound is advanced), and the operation noise is suppressed from conspicuous.

  In the present embodiment, when the lock energization time is set to the second time t2, the lock energization is performed again when the vehicle speed subsequently exceeds the reference value. This will be described in detail. After the lock energization time set at the second time t2 has elapsed and the relay 12 is turned off, the controller 10 communicates with the vehicle speed sensor 8 and indicates the traveling speed at that time. A detection signal is received from the vehicle speed sensor 8 (S010).

Then, the controller 10 performs lock energization again when both of the following conditions (1) and (2) are satisfied (S011, S12).
(1) The current position of the window glass 2 is in the closed position. (2) The current value of the running speed of the vehicle after the second time t2 has elapsed is greater than or equal to a reference value. The reference value used for the determination is the same value as the reference value used at the stage of setting the lock energization time (that is, the reference value used in step S003). However, the present invention is not limited to this, and the two reference values may be different from each other.

  Then, after the re-lock energization is completed, the controller 10 turns off the relay 12 again (S013). Note that the execution time (continuation time) of the re-lock energization is not particularly limited and can be arbitrarily set. Preferably, the time is equal to or greater than the difference between the first time t1 and the second time t2. It is good to set to.

  As described above, in this embodiment, when the lock energization time is set to the second time t2, lock energization is performed again when the above two conditions are satisfied after the lock energization time has elapsed. That is, the controller 10 according to the present embodiment has the traveling speed specified by the speed detection signal received from the vehicle speed sensor 8 after the second time t2 elapses equal to or higher than the reference value, and the window glass 2 at that time. Is in the closed position, the forward rotation relay 12 is turned on in order to resume the power supply to the motor 3. As a result, the window glass 2 moves in the same direction as that when moving toward the closed position, that is, upward. As a result, the upper end portion of the window glass 2 sufficiently bites into the weather strip 1b. That is, even if the lock energization time immediately after the window glass 2 reaches the closed position is short, the window glass 2 can be reliably closed by executing the re-energization.

  In addition, if the lock energization time immediately after the window glass 2 reaches the closed position is short, the degree of adhesion between the weather strip 1b and the window glass 2 becomes relatively small, so that the wind passes through the gap between the two and the noise is abnormal. (Wind noise) may occur. On the other hand, the generation of the wind noise described above can be suppressed by re-execution of the lock energization to reliably close the window glass 2.

  In the embodiment described above, the power window device S which is an example of the opening / closing member control device of the present invention has been mainly described. However, the above embodiment is merely an example for facilitating understanding of the present invention, and does not limit the present invention.
