Abstract

To provide an opening/closing member control apparatus that can reduce a collision noise of a spring.SOLUTION: A control apparatus opens and closes a window glass whose tip end portion is sandwiched between glass runs in a fully closed state via an opening wire by reversing and forwarding a motor. An end portion of the opening wire is slidably attached to a slider base via a spring member. The control apparatus determines whether an energization off condition of the motor is satisfied after the motor is started to drive to operate the window glass from the fully closed state in an open direction and in a state where the tip end portion is sandwiched between the glass runs (S10, S11). The control apparatus turns off the energization to the motor when the energization off condition is satisfied (S15). Then, the control apparatus restarts operation of the motor when a re-energization on condition of the motor is satisfied after the energization off (S16, S17).SELECTED DRAWING: Figure 6

Description

The present disclosure relates to an opening/closing member control device.

As an example of an opening/closing member control device, there is a technique for opening and closing a window glass as an opening/closing member using a wire regulator device (hereinafter referred to as a regulator) disclosed in Patent Document 1.

Japanese Patent Application Laid-Open No. 2004-190394

The regulator includes a wire and a fixing member for fixing the wire to the window glass. The ends of the wires are slidably attached to the fixed member via spring members. An opening/closing member control device using a regulator rotates a motor to wind a wire, thereby opening or closing a window glass fixed to a fixing member.

By the way, the tip of the window glass is sandwiched between the seal portions attached to the window frame in the fully closed state. Therefore, when the window glass is opened from the fully closed state, friction occurs between the window glass and the sealing portion. Also, the regulator contracts the spring member by winding the wire. Then, when the window glass comes out of the seal portion, a reaction force against the friction is generated and the window glass is rapidly accelerated in the opening direction.

This may cause the spring member to slide and the regulator to collide with the fixed member. In addition, the regulator may repeatedly collide with the spring member and the fixed member as the window glass moves in the opening direction. In this case, the regulator generates sound when the spring member collides with the fixed member.

One object of the disclosure is to provide an opening/closing member control device capable of reducing collision noise of a spring member.

The opening/closing member control device disclosed herein includes:
An opening/closing member whose tip is sandwiched by a sealing member in a fully closed state is opened and closed via a wire by rotating an electric motor forward and reverse. , slidably mounted via a spring member,
a drive start section (S10) for starting the driving of the electric motor in order to operate the opening/closing member in the opening direction from the fully closed state; a drive stop determination unit (S11) that determines whether or not a drive stop condition for the electric motor is satisfied;
a drive stop unit (S15) for stopping the driving of the electric motor when it is determined that the drive stop condition is satisfied;
a re-driving determination unit (S16) that determines whether or not a condition for re-driving the electric motor is satisfied after the driving of the electric motor is stopped;
and a re-driving unit (S17) for re-driving the electric motor when it is determined that the re-driving condition is satisfied.

In this way, the opening/closing member control device stops the driving of the electric motor when the driving stop condition of the electric motor is satisfied after the driving of the electric motor is started and the tip portion is sandwiched between the sealing members. Therefore, the opening/closing member control device can weaken the reaction force against the friction between the opening/closing member and the seal portion when the opening/closing member comes out of the seal portion.

Then, after stopping the driving of the electric motor, the opening/closing member control device re-drives the electric motor when the re-driving condition of the electric motor is satisfied. Therefore, the opening/closing member control device can prevent the spring member from sliding and colliding with the fixed member. Therefore, the opening/closing member control device can reduce the collision noise of the spring member.

<Overall composition>
In this embodiment, an example in which the opening/closing member control device is applied to the control device 100 is adopted. Control device 100 is configured to be mountable on a vehicle. Moreover, in this embodiment, the window glass 410 of a vehicle is used as an example of the opening/closing member. Therefore, the control device 100 controls opening and closing of the window glass 410 as an opening and closing member.

As shown in FIG. 1, the control device 100 includes a controller 1, a drive circuit 2, and the like. Control device 100 is electrically connected to battery 500 . The control device 100 is powered by a battery 500 to operate. In the control device 100 , power is supplied from the battery 500 to the controller 1 and the drive circuit 2 . The configuration and processing operations of the control device 100 will be described later in detail.

A switch device 200 , a body ECU 210 , a motor 300 and a rotation sensor 310 are electrically connected to the control device 100 . Control device 100 rotates motor 300 forward and backward to raise and lower (open and close) window glass 410 via wires 425 and 426 . The configuration of the door 400 provided with the window glass 410 will be described later in detail. Motor 300 corresponds to an electric motor.

The switch device 200 is provided inside the vehicle. The switch device 200 includes an up switch 201, a down switch 202, an auto switch 203, etc. that can be operated by the user of the vehicle.

The lift switch 201 is a switch for closing the window glass 410 . When lift switch 201 is operated and turned on, it outputs to controller 1 a normally closed command signal for normally closing window glass 410 . The normal closing operation means that the closing operation is performed only while the lift switch 201 is being operated. Note that the rise switch 201 can also be said to be a close switch. Also, the normal closing operation can be said to be a manual closing operation.

The lowering switch 202 is a switch for opening the window glass 410 . When lowered switch 202 is operated and turned on, it outputs to controller 1 a normally open command signal for normally opening window glass 410 . The normal open operation means that the open operation is performed only while the lowering switch 202 is being operated. It should be noted that the descending switch 202 can also be said to be an open switch. Further, the normal opening operation can also be said to be a manual opening operation.

The auto switch 203 is a switch that automatically operates the window glass 410 . When the auto switch 203 is turned on by being operated together with the lift switch 201 , it outputs an auto close signal to the controller 1 for automatically closing the window glass 410 . When the auto switch 203 is turned on by being operated together with the down switch 202 , it outputs an auto open signal to the controller 1 for automatically opening the window glass 410 . The automatic closing operation and the automatic opening operation mean that the window glass 410 operates even if the operation of the up switch 201 or the down switch 202 is stopped.

The body ECU 210 includes an arithmetic device such as a CPU, a storage device including RAM and ROM, a wireless communication device, an interface, and the like. Body ECU 210 is provided in the vehicle. The body ECU 210 outputs various signals to the controller 1, including remote control signals and interlocking actuation signals. The remote control signal is a signal received by the wireless communication device, which is transmitted according to the operation of the switches 221 and 222 of the wireless switch device 220 . The remote control signal will be explained later in detail.

The interlocking actuation signal is a signal generated in response to the operation of a vehicle key or doorknob. The body ECU 210, for example, interlocks with the key operation by the user to generate an interlocking operation signal indicating a close command signal for key-linked closing operation of the window glass 410 or an interlocking operation signal indicating an open command signal for key-linked opening operation. Output a signal.

The wireless switch device 220 includes an up switch 221, a down switch 222, and the like. The wireless switch device 220 performs remote operation of the window glass 410 from outside the vehicle, and is integrated with a portable device using radio waves, infrared rays, or the like. Wireless switch device 220 is configured to be able to wirelessly communicate with body ECU 210 . When lift switch 201 is operated and turned on, it transmits a remote control signal indicating a close command signal for remotely closing window glass 410 . When lowered switch 222 is operated and turned on, it transmits a remote control signal indicating an open command signal for remotely opening window glass 410 .

Motor 300 is rotationally driven by control device 100 . The rotation sensor 310 is configured to detect a magnetic change of a magnet that rotates together with the output shaft of the motor 300 using a plurality of Hall elements. Note that the rotation of the motor 300 indicates that the rotor provided in the motor 300 rotates. Therefore, the number of rotations of the motor 300 is the number of rotations of the rotor.

<Door configuration>
Here, the configuration of the door 400 will be described with reference to FIGS. 2, 3, and 4. FIG. As shown in FIG. 2, the door 400 includes a glass run 401 provided on the window frame, a window glass 410 for opening and closing the window frame, a regulator 420 for driving the window glass 410, and the like.

A glass run 401 is a sealing member attached to a window frame of a vehicle. The glass run 401 is mainly composed of resin, for example. The glass run 401 is provided to close the gap between the window glass 410 and the window frame to prevent noise, rain, wind, etc. from entering the passenger compartment.

Window glass 410 is configured to be movable between a fully closed position and a fully open position. That is, as shown in FIG. 2, window glass 410 is configured to be movable in closing direction UD and opening direction DD.

As shown in FIG. 3, the tip of the window glass 410 is sandwiched between the glass runs 401 in a fully closed state. Further, the tip portion of the window glass 410 is sandwiched between the glass runs 401 not only in the fully closed state but also in a state in which the window glass 410 is moved from the fully closed state to the opening direction by a predetermined distance. That is, the tip of the window glass 410 moves outside the glass run 401 by moving beyond the predetermined distance from the fully closed position. Note that the tip of the window glass 410 can also be said to be the edge of the window glass 410 .

Hereinafter, the state in which part of the window glass 410 is sandwiched between the glass runs 401 may be simply described as a state of being sandwiched between the glass runs 401 . The state in which part of the window glass 410 is sandwiched between the glass runs 401 can also be referred to as a state in which the window glass 410 is arranged within the glass run 401 .

The glass run 401 is provided for the purpose as described above. Therefore, it can be said that the window glass 410 is in close contact with the glass run 401 while being sandwiched between the glass runs 401 .

As shown in FIG. 2, the regulator 420 includes a slider base 421, a driving pulley 422, driven pulleys 423 and 424, an opening wire 425, a closing wire 426, a spring member 427, and the like. The opening wire 425 corresponds to a wire.

Regulator 420 is a device that drives window glass 410 together with motor 300 attached to the door. Therefore, the motor 300 and the regulator 420 can also be said to be a drive mechanism for the window glass 410 .

Slider base 421 is a member that fixes wires 425 and 436 and window glass 410 . The slider base 421 is fixed to the window glass 410 with screws or the like. The slider base 421 is fixed to the lower end side of the window glass 410, for example. The slider base 421 corresponds to a fixed member.

Also, as shown in FIG. 4, the end of an opening wire 425 is slidably attached to the slider base 421 via a spring member 427 . Specifically, the slider base 421 has a spring accommodating portion 421a in which the spring member 427 is accommodated. A spring member 427 is attached to the end of the opening wire 425 . The spring member 427 is slidably housed in the spring housing portion 421a. Further, the spring member 427 is accommodated in the spring accommodating portion 421a in a state capable of compressive deformation and elastic deformation.

The slider base 421 is similarly attached to the closing wire 426 so as to be slidable via a spring member. FIG. 4a shows a state in which force is applied to the spring member 427 and the spring member 427 is bent (compressed state). FIG. 4b shows the state in which the spring member 427 is not flexed.

The drive pulley 422 is connected to the output shaft of the motor 20 . The opening wire 425 is stretched over the driving pulley 422 and the driven pulley 424 . A closing wire 426 is stretched over the driving pulley 422 and the driven pulley 423 .

In regulator 420 , drive pulley 422 rotates as motor 20 rotates. Then, the regulator 420 moves the window glass 410 in the opening direction DD by winding the opening wire 425 by the rotation of the driving pulley 422 . Further, the regulator 420 moves the window glass 410 in the closing direction UD by winding the closing wire 426 due to the rotation of the drive pulley 422 . That is, the window glass 410 moves in the opening direction DD when the slider base 421 is pulled from the opening wire 425 via the spring member 427 . On the other hand, the window glass 410 moves in the closing direction UD as the slider base 421 is pulled from the closing movement wire 426 via the spring member.

Note that the rotation of the motor 20 is opposite between the opening direction DD and the closing direction UD. In the following, processing operation and configuration when moving window glass 410 in opening direction DD will be mainly described.

The spring member 427 employs, for example, a compression coil spring. Spring member 427 is energized by opening wire 425 . The spring member 427 is deformed (compressed) when the rotation speed of the motor 300 is faster than the movement speed of the window glass 410 when the opening wire 425 is wound as the motor 300 rotates. Further, as shown in FIG. 4a, the spring member 427 may deform to or near its compression limit if the rotational speed of the motor 300 is sufficiently faster than the moving speed of the window glass 410. FIG. 4B, the spring member 427 is elastically deformed when the moving speed of the window glass 410 is sufficiently faster than the rotating speed of the motor 300. As shown in FIG.

<Configuration of control device>
The configuration of the control device 100 will be described with reference to FIG. The controller 1 includes an arithmetic device 11 such as a CPU, and a storage device 12 including RAM, ROM, and the like. Furthermore, the controller 1 may have an interface and the like. The controller 1 receives signals as described above from the switch device 200 and the body ECU 210 .

The arithmetic device 11 performs arithmetic processing using data and the like by executing a program. The storage device 12 stores programs that can be executed by the arithmetic device 11, data that the arithmetic device 11 uses for arithmetic processing, and the like.

The arithmetic device 11 drives and controls the drive circuit 2 based on signals from the switch device 200 and the like. The arithmetic unit 11 drives and controls the drive circuit 2 to control the power supply to the motor 300 and rotate the motor 300 . In this manner, control device 100 opens and closes window glass 410 . Note that supplying power to the motor 300 to move the window glass 410 in the opening direction DD is also referred to as down operation.

Further, the arithmetic device 11 performs various functions by performing arithmetic processing. Therefore, it can be said that the arithmetic unit 11 has various functional blocks. The computing device 11 has, for example, a window position detector 11a and a rotation speed detector 11b as functional blocks. The storage device 12 stores, as data, such signals as those described above, the detection results of the window position detection section 11a and the rotation speed detection section 11b, and the like.

Rotational speed detection unit 11 b detects the rotational speed of motor 300 based on the electrical signal output from rotation sensor 310 for detecting the rotational speed of motor 300 . That is, the rotational speed detection unit 11 b detects the rotational speed of the motor 300 based on the edge (pulse edge) of the pulse signal, which is the electrical signal output from the rotation sensor 310 . Note that the rotation speed detection unit 11b detects the rotation speed based on the rising edge or the falling edge of the pulse signal. Further, the rotation speed detection unit 11b may detect the rotation direction of the motor 300 based on the phase difference of each pulse signal.

Window position detector 11a detects the position of window glass 410 based on the pulse signal. That is, the window position detector 11a counts pulse edges. This pulse count value is added or subtracted as the window glass 410 is opened or closed. Window position detector 11a can specify the open/closed position of window glass 410 based on the magnitude of the pulse count value.

The window position detection unit 11a can drive the window glass 410, for example, using the fully closed position of the window glass 410 as a reference position. When the fully closed position is set as the reference position, the pulse count value is set to 0 at the fully closed position. Then, the window position detection unit 11a increments the pulse count value by 1 each time it receives a pulse signal when the window glass 410 is moving toward one end of the operation area (operation section), for example, in the opening direction DD. Further, the window position detector 11a decrements the pulse count value by 1 each time it receives a pulse signal when the window glass 410 is moving toward the other end side of the operating region, ie, the closing direction UD.

Note that the window position detection unit 11a may drive the window glass 410 with the fully open position as the reference position. In this case, the pulse count value is set to "0" at the fully open position. Then, window position detector 11a increments the pulse count value while window glass 410 is moving in closing direction UD. On the other hand, the window position detector 11a decrements the pulse count value when the window glass 410 is moving toward the fully open position.

In addition, the controller 1 has, for example, a self-seat manual mode, a self-seat auto mode, a remote manual mode, and a key interlocking mode as operation modes for operating the window glass 410 . Controller 1 selects an operation mode according to an operation signal for operating window glass 410 . The controller 1 then operates the window glass 410 according to the selected operating mode. Operation modes include a self-seat manual mode, a self-seat auto mode, a remote manual mode, and a key interlocking mode.

The self-seat manual mode is a mode in which a manual closing operation and a manual opening operation are performed. The controller 1 selects the self-seat manual mode when the normally close command signal or the normally open command signal is input.

The self-seat auto mode is a mode in which auto-close operation and auto-open operation are performed. The controller 1 selects the self-seat auto mode when the auto close signal or the auto open signal is input.

The remote manual mode is a mode in which remote close operation and remote open operation are performed. The controller 1 selects the remote manual mode when a remote control signal indicating a close command signal or a remote control signal indicating an open command signal is input.

The key-linked mode is a mode in which a key-linked closing operation and a key-linked opening operation are performed. The controller 1 selects the key interlock mode when the interlock actuation signal indicating the close command signal or the interlock actuation signal indicating the open command signal is input.

In this embodiment, as an example of the actuation signal, a normal close command signal, a normal open command signal, an auto-close signal, an auto-open signal, an interlock actuation signal, and a remote control signal are employed. However, the present disclosure is not so limited. For example, a configuration that uses only the normally closed command signal and the normally open command signal as the actuation signals can be employed.

The drive circuit 2 rotates with the motor 300 according to an instruction value (input signal) from the controller 1 . More specifically, the drive circuit 2 has switching elements and the like. The drive circuit 2 switches the polarity of power supply to the motor 300 based on the input signal from the controller 1 . That is, when the drive circuit 2 receives a forward rotation command value as an input signal from the controller 1, it supplies power to the motor 20 so as to rotate the motor 300 in the forward rotation direction. On the other hand, when the drive circuit 2 receives a reverse rotation command value as an input signal from the controller 1, it supplies power to the motor 20 so as to rotate the motor 20 in the reverse rotation direction.

<Processing operation>
Here, processing operations of the control device 100 will be described with reference to FIGS. 5 to 10. FIG.

Generally, as indicated by the dotted line in FIG. 5, a control device for controlling the opening and closing (lifting) of the window glass takes two states, ie, during stop and during down operation. On the other hand, as indicated by the dotted line and the solid line in FIG. 5, the control device 100 is in a state of waiting for reactivation of the down motion in addition to being stopped and in the down motion. This is because the power supply to the motor 300 is temporarily stopped (energization is turned off) and the power supply to the motor 300 is restarted while the control device 100 is in the down operation. This point will be described in detail with reference to the flow chart of FIG. Note that "waiting for reactivation of down" is also described as "waiting for reactivation". FIG. 5 is a state transition diagram during operation in the self-seat manual mode.

The control device 100 starts the process shown in the flowchart of FIG. 6 at predetermined time intervals when the actuation signal is input. Note that the flow chart of FIG. 6 is mainly performed by the controller 1 provided in the control device 100 .

In step S10, start-up processing is performed. The controller 1 determines the operating mode based on the operating signal. Then, the controller 1 energizes the motor 300 according to the determined operation mode (energization ON). The controller 1 starts energizing the motor 300 when the window glass 410 is fully closed (stopped) and an actuation signal such as a normal open command signal for operating the window glass 410 in the opening direction DD is input. . That is, the controller 1 starts driving the motor 300 to operate the window glass 410 from the fully closed state in the opening direction DD (driving start section). In the following description, energization of motor 300 is also simply referred to as energization.

In this case, the controller 1 starts energization when the window glass 410 is in the fully closed position, as shown in FIG. Also, as shown in FIG. 8, energization is started at x1. As a result, the voltage applied to the motor 300 gradually increases. In FIG. 8, the solid line indicates the command value, and the dashed-dotted line indicates the actual energized voltage.

Furthermore, as shown in FIG. 9b, when the energization is started at t0, the rotational speed of the motor 300 increases and the position of the window glass 410 moves. As a result, the control device 100 makes a state transition from being stopped to being down.

In the example of FIG. 7, the fully closed position is the position where the number of pulse edges is ten. The glass run position in FIG. 7 indicates the position of the end of the glass run 401 . Therefore, the tip of the window glass 410 is sandwiched between the glass runs 401 when the number of pulse edges is between 10 and 30. FIG.

On the other hand, when the number of pulse edges exceeds 30, the tip of the window glass 410 is arranged outside the glass run 401 . Therefore, the window glass 410 is not sandwiched between the glass runs 401 .

FIG. 9b shows the relationship between the number of revolutions and the number of pulse edges when energization is controlled by the control device 100. FIG. FIG. 9a shows the relationship between the number of rotations and the number of pulse edges in a configuration (comparative example apparatus) in which the power supply is not temporarily turned off during the down operation. Timings t0 to t2 in ab of FIG. 9 show the relationship between the number of revolutions and the number of pulse edges in the state sandwiched between the glass runs 401. FIG. Timings t2 to t3 in ab of FIG. 9 show the relationship between the number of rotations and the number of pulse edges immediately after the window glass 410 is pulled out of the glass run 401 . Timings t3 to t4 in ab of FIG. 9 show the relationship between the number of rotations and the number of pulse edges after the window glass 410 is removed from the glass run 401 and the number of rotations increases.

In step S11, it is determined whether or not the power supply OFF condition is satisfied (driving stop determination unit). After the motor 300 has started to be driven and the tip of the window glass 410 is sandwiched between the sealing members, the controller 1 determines whether or not the condition for de-energizing the motor 300 is satisfied.

The controller 1 acquires the number of rotations of the motor 300 at predetermined time intervals (the number of rotations detector 11b). For example, the controller 1 starts obtaining the number of rotations when energization is started. Then, the controller 1 acquires the number of revolutions at predetermined time intervals.

The controller 1 stores the rotation speed when the rotation speed is reduced in RAM or the like as a reference value. That is, the controller 1 subtracts the number of revolutions acquired last time from the number of revolutions acquired this time. Then, if the result of the subtraction is less than 0, the controller 1 stores the number of revolutions acquired this time as a reference value. In the example of FIG. 9b, the number of rotations at timing t1 is saved. Furthermore, the controller 1 determines that the energization OFF condition is established when the rotational speed deviation from the reference value in the rotational speed acquired at predetermined time intervals is equal to or greater than the stop threshold. The energization off condition corresponds to the driving stop condition.

Note that the control device 100 may have a full power opening operation mode in which the window glass 410 is opened with full power when the temperature is low. In such a configuration, the control device 100 may determine that the energization OFF condition is not satisfied when the full power open operation mode is selected.

The energization off condition is not limited to the above. A distance from the fully closed position of the window glass 410 can also be used as the de-energization condition. The controller 1 may determine that the de-energization condition is met when the window glass 410 moves a predetermined stop distance or more from the fully closed position of the window glass 410 (driving stop determination unit).

In this case, the controller 1 uses the position of the windowpane 410 detected by the window position detector 11a to determine whether the windowpane 410 has moved more than the stopping distance. Further, the controller 1 may determine whether or not the window glass 410 has moved more than the stopping distance based on the elapsed time from the start of energization.

In step S12, the operation mode before power-off is saved. The controller 1 saves the operation mode determined in step S10 in RAM or the like. This is to operate the window glass 410 in the same operation mode as before the energization is turned off when the energization is restarted after the energization is temporarily turned off. However, the controller 1 can omit step S12 when operating the window glass 410 in only one operating mode.

In step S13, the state is set to a down restart waiting state. The controller 1 saves in the RAM or the like standby information indicating a state transition to a down restart waiting state.

In step S14, it is determined whether or not the state is to be changed to waiting for the down operation again. The controller 1 determines based on whether or not standby information is stored. When the standby information is stored, the controller 1 determines that the state transitions to waiting for down motion reactivation, and proceeds to step S15. If the standby information is not stored, the controller 1 determines that the state is not changed to waiting for reactivation of the down state, and terminates the flowchart.

In step S15, the power supply is turned off (driving stop section). The controller 1 stops energization when it is determined that the energization off condition is satisfied. In other words, the controller 1 temporarily stops energization during the down operation. As a result, the control device 100 makes a state transition from during the down operation to waiting for the down operation again.

The controller 1 stops energization at x2, as shown in FIG. That is, the controller 1 outputs an instruction value to stop energization. As a result, the energized voltage gradually decreases. In other words, the controller 1 stops driving the motor 300 .

In the example of FIG. 7, the controller 1 turns off the power supply at the pulse edge number of 26 positions. When the number of pulse edges is 26, the tip of the window glass 410 is sandwiched between the glass runs 401 . In other words, the controller 1 stops energization while the tip of the window glass 410 is sandwiched between the glass runs 401 . It can also be said that the controller 1 stops energization while a part of the window glass 410 remains inside the glass run 401 .

Moreover, in the example of b of FIG. 9, the energization is stopped between the timing t1 and the timing t2. The rotation speed of the motor 300 does not immediately become 0 even when the power supply is stopped, but the rotation speed gradually decreases. Therefore, the window glass 410 moves in the opening direction DD even if the window glass 410 is stopped. The movement of the window glass 410 in a state in which the energization is stopped is referred to as idling.

Here, the idling distance (the number of pulse edges) will be described with reference to FIG. FIG. 10 shows the results of measuring the moving distance of the window glass 410 when the current supply is actually stopped. When the energization of the motor 300 at 10 V was stopped, the window glass 410 moved in the opening direction DD by 5 pulse edges. Further, when the voltage of 14 V was stopped from being applied to the motor 300, the window glass 410 moved in the opening direction DD by 9 pulse edges.

In this way, the free running distance can be grasped in advance through experiments, simulations, or the like. Further, the position of the glass run within the moving range of the window glass 410 can also be grasped in advance. Therefore, the controller 1 grasps the relationship between the voltage applied to the motor 300 and the idling distance, and the position of the glass run. Glass 410 can be pulled out of glass run 401 .

In the example of FIG. 7, the controller 1 stops energization at the pulse edge number of 26. In the example of FIG. That is, the window glass 410 idles from the pulse edge number of 26. The window glass 410 idles up to a position exceeding 30 pulse edges.

Note that pulling the tip of the window glass 410 out of the glass run 401 means that the window glass 410 can be moved to a position where the tip of the window glass 410 is arranged outside the glass run 401 . In other words, the state in which the tip of the window glass 410 is removed from the glass run 401 is the state in which the entire window glass 410 is arranged outside the glass run 401 .

As shown in FIG. 9a, in the comparative example, the power supply is not temporarily turned off during the down operation, so the rotational speed rises sharply between timings t2 and t3. That is, in the device of the comparative example, the window glass 410 is rapidly accelerated immediately after the window glass 410 leaves the glass run 401 .

On the other hand, the control device 100 temporarily stops the energization and moves the window glass 410 to the outside of the glass run 401 while the energization is stopped. In other words, the control device 100 once slows down the moving speed of the window glass 410 while the window glass 410 is sandwiched between the glass runs 401 and then moves the window glass 410 to the outside of the glass run 401 . Therefore, at timings t2 to t3 in FIG. 9b, an increase in the number of revolutions can be suppressed more than in FIG. 9a. In other words, control device 100 can suppress rapid acceleration of window glass 410 immediately after window glass 410 exits glass run 401 .

In addition, it can be said that the control device 100 provides an energization stop section in which energization to the motor 300 is stopped. The de-energization section is at least a portion between the position moved in the glass run position direction from the fully closed position and the glass run position. Furthermore, it can be said that the control device 100 provides an energization stop period during which energization to the motor 300 is stopped. The de-energization period is a predetermined period after the window glass 410 starts moving from the fully closed position in the opening direction DD and at least before the window glass 410 comes out of the glass run 401 .

In step S16, it is determined whether or not the reenergization ON condition is established (re-driving determination unit). After stopping the driving of the motor 300, the controller 1 determines whether or not the reenergization ON condition of the motor 300 is satisfied. That is, the controller 1 determines whether or not the condition for resuming the energization is satisfied after the energization is turned off in step S15. The controller 1 proceeds to step S17 when determining that the reenergization ON condition is satisfied, and repeats step S16 when determining that it is not satisfied. The re-energization ON condition corresponds to the re-driving condition.

The controller 1 determines that the reenergization ON condition is satisfied when the window glass 410 moves a preset re-driving distance or more after the power is turned off in step S15 (re-driving determination section). In this case, the controller 1 uses the position of the windowpane 410 detected by the window position detector 11a to determine whether the windowpane 410 has moved more than the re-driving distance after the power supply is turned off. Further, the controller 1 may determine whether or not the window glass 410 has moved more than the re-driving distance based on the elapsed time after the power supply is turned off.

Further, the controller 1 may determine that the reenergization ON condition is satisfied when the rotation speed of the motor 300 becomes equal to or greater than a preset rotation speed threshold after the power supply is turned off in step S15 (redrive determination unit). . The controller 1 may acquire the number of rotations of the motor 300 at predetermined time intervals after the power supply is turned off in step S15, and may determine that the reenergization ON condition is satisfied when the number of rotations increases (re-driving determination part).

In step S17, the operation before stopping is resumed (re-driving section). In other words, the controller 1 resumes energization while waiting for reactivation. As a result, the control device 100 makes a state transition from during the down operation to waiting for the down operation again. As a result, the control device 100 transitions from waiting for reactivation to down operation.

The controller 1, as shown in FIG. 8, restarts the energization during the energization stop of x2 to x3. That is, the controller 1 outputs an instruction value to start energization. As a result, the energized voltage gradually rises. In other words, controller 1 re-drives motor 300 .

In the example of FIG. 7, the controller 1 restarts energization at a position where the number of pulse edges exceeds 30. When the number of pulse edges exceeds 30, the tip of the window glass 410 is not sandwiched between the glass runs 401 . That is, the controller 1 resumes energization of the motor 300 with the window glass 410 removed from the glass run 401 . However, the present disclosure may resume energization before the window glass 410 is removed from the glass run 401 if the energization is temporarily stopped in step S15.

<effect>
As described above, control device 100 rotationally drives motor 300 to move window glass 410 in opening direction DD. At this time, the control device 100 drives the motor 300 when the motor 300 has started to be driven and the energization off condition of the motor 300 is satisfied in a state where the tip of the window glass 410 is sandwiched between the glass runs 401. Stop. Therefore, control device 100 can slow down the moving speed of window glass 410 before window glass 410 leaves glass run 401 . Therefore, control device 100 can weaken the reaction force against the friction between window glass 410 and glass run 401 when window glass 410 is removed from glass run 401 .

After the driving of the motor 300 is stopped, the control device 100 re-drives the motor 300 when the re-energization ON condition of the motor 300 is satisfied. Therefore, the control device 100 can prevent the spring member 427 from sliding and colliding with the slider base 421 (spring accommodating portion 421a). Therefore, the control device 100 can reduce the collision noise of the spring member 427 . Note that the impact sound can also be called a shudder sound.

Here, the effect of the control device 100 will be described in comparison with the comparative example device. As shown in timings t2 to t3 in FIG. 9a, in the comparative example, when the window glass comes out of the glass run, a reaction force against the friction is generated and the glass is rapidly accelerated in the opening direction DD. As a result, the spring member of the regulator slides, and the spring member collides with the slider base to generate a shudder sound. Further, the motor controlled by the comparative example device repeats an increase and a decrease in the number of revolutions, as shown at timings t3 to t4 in FIG. 9a. Therefore, in the regulator, collision between the spring member and the slider base occurs repeatedly as the window glass moves in the opening direction DD. Therefore, the regulator continuously generates shudder noise.

In response to this, the control device 100 performs step S15. Therefore, as shown in timings t2 to t3 in FIG. 9b, the control device 100 can suppress rapid acceleration in the opening direction DD when the window glass 410 comes out of the glass run 401. FIG. Thereby, the control device 100 can prevent the spring member 427 from sliding and colliding with the slider base 421 . That is, the control device 100 can suppress the generation of the shudder sound.

Furthermore, the motor 300 is prevented from repeating an increase and a decrease in the number of revolutions, as shown at timings t3 to t4 in FIG. 9b. Therefore, the regulator 420 can prevent repeated collisions between the spring member 427 and the slider base 421 as the window glass 410 moves in the opening direction DD. Therefore, the control device 100 can suppress continuous generation of the shudder sound.

In this way, the control device 100 can reduce the shudder noise by controlling the driving of the motor 300 . That is, the control device 100 can reduce the shudder noise without taking measures against the shudder noise for the window glass 410 , the regulator 420 , and the motor 300 . As a result, it is possible to reduce countermeasure costs for OEMs and regulator manufacturers.
