  By the way, when moving both the first opening/closing member and the second opening/closing member at the same time at the same time, one of the first opening/closing member and the second opening/closing member may overtake the other, or the like. The positions may be separated. If the opening/closing members are separated from each other while the opening/closing members are simultaneously moved in the same direction in this way, the opening/closing members may not be opened and closed smoothly, and the usability for the user may be impaired. ..

  Therefore, the present invention has been made in view of the above problems, and an object thereof is a user-friendly as an opening/closing member control device that simultaneously moves the first opening/closing member and the second opening/closing member that are aligned with each other in the same direction.

According to the opening/closing member control device of the present invention, the problem includes a motor that drives the first opening/closing member to open and close, and a control unit that controls the motor. When simultaneously moving both the first opening/closing member and the second opening/closing member adjacent to each other in the same direction, the control unit controls the current position of the second opening/closing member in the movement range of the second opening/closing member. Is obtained, and the motor is controlled so that the first opening/closing member moves at a moving speed corresponding to the index, and the motor drives the first opening/closing member to open/close. A first motor, the control unit is a first control unit that controls the first motor, and a second motor that drives the second opening and closing member to open and close, and a second motor that controls the second motor. And a second control unit, when simultaneously moving both the first opening and closing member and the second opening and closing member in the same direction, in conjunction with the rotation start of the first motor by the first control unit, The second control unit solves the problem by rotating the second motor .

  In the opening/closing member control device of the present invention configured as described above, when simultaneously moving the first opening/closing member and the second opening/closing member that are arranged next to each other in the same direction, an index indicating the current position of the second opening/closing member. The motor is controlled so that the first opening/closing member moves at a moving speed corresponding to Accordingly, it is possible to avoid the situation where the opening/closing members are separated from each other while simultaneously moving the opening/closing members in the same direction, and it is possible to smoothly open/close each opening/closing member. With the above configuration, an opening/closing member control device that is convenient for the user can be realized.

Further, if the configuration described above, each of the first closing member and second closing member as an opening and closing member control device for opening and closing movement by the rotational force of the motor, can be convenient for the user to realize a device Become.

Further, with respect to the opening/closing member control device, a signal output device that outputs a signal each time the second motor rotates by a unit number of revolutions is provided, and the first control unit controls the signal output from the signal output device. A count number may be acquired as the index, and the first motor may be controlled based on the count number.
With the above configuration, by controlling the first motor based on the count number of the signal output from the signal output device, the first motor can be appropriately controlled according to the current position of the second opening/closing member. It will be possible.

The opening/closing member control device further includes a first pulse signal output device that outputs a pulse signal each time the first motor rotates by a unit number of revolutions, and the signal output device includes the second motor as a unit. It is a second pulse signal output device that outputs a pulse signal every time it rotates by the number of rotations, the first control unit, the count number of the pulse signal output from the first pulse signal output device and the second pulse signal. It is further preferable to control the first motor based on a difference from the count number of the pulse signal output from the output device.
In the above configuration, the first motor is controlled based on the difference between the count number of the pulse signal output from the first pulse signal output device and the count number of the pulse signal output from the second pulse signal output device. . That is, the first motor is controlled based on the deviation between the current position of the first opening/closing member and the current position of the second opening/closing member. With such a configuration, it is possible to more effectively avoid the situation where the opening/closing members are separated from each other while both opening/closing members are simultaneously moved in the same direction.

In the above configuration, in the configuration in which the second opening/closing member is located closer to the vehicle compartment than the first opening/closing member, the current position of the first opening/closing member is the same when moving both opening/closing members in the same direction at the same time. The motor (in other words, the moving speed of the first opening/closing member) is controlled so as to maintain a state in which the second opening/closing member is away from the current position (open position). This makes it possible to prevent the second opening/closing member located on the vehicle interior side from being exposed to the outside air while being exposed.

Further, in the opening/closing member control device, the motor is driven to open/close the window glass as the first opening/closing member, and both the window glass and the awning member as the second opening/closing member.

  Note that the embodiments described below are for facilitating the understanding of the present invention and do not limit the present invention. That is, the present invention can be modified and improved without departing from the spirit thereof and, of course, the present invention includes equivalents thereof.

  An opening/closing member control device of the present embodiment (hereinafter referred to as the present device 1) is mounted on a vehicle, opens and closes a window glass provided on a vehicle door, and opens and closes a sunshade arranged in proximity to the window glass. To move. The window glass corresponds to the first opening/closing member in this embodiment. The sunshade corresponds to the second opening/closing member in the present embodiment. The window glass and the sunshade are both provided to open and close an opening provided in the vehicle door, and move between a position where the opening is opened (fully open position) and a position where the opening is closed (fully closed position).

  Explaining the sunshade in detail, the sunshade is a sheet-shaped sunshade member, is arranged next to the window glass, and is arranged closer to the passenger compartment than the window glass. The sunshade is stored in the door trim of the vehicle door when in the fully open position and closes the opening of the vehicle door when in the fully closed position. The sunshade is large enough to close the opening of the vehicle door. Therefore, when both the window glass and the sunshade are in the fully closed position, the sunshade covers substantially the entire window glass from the passenger compartment side.

  Explaining the configuration of the present device 1, the present device 1 is configured by a power window unit 10, a sunshade drive unit 30, and a main body ECU (Electric Control Unit) 50 that mediates these, as shown in FIG. There is.

  The power window unit 10 is a part of the device 1 that controls opening/closing movement of the window glass. The power window unit 10 includes a motor as a drive source (hereinafter, a power window motor 11) and an elevating mechanism (not shown) for elevating the window glass. The power window motor 11 corresponds to the first motor in this embodiment, and is rotationally driven to open and close the window glass. The elevating mechanism moves up and down (opens and closes) the window glass by operating using the rotational force of the power window motor 11. Note that, although a description of the specific configuration of the lifting mechanism is omitted, a known mechanism (for example, an X-arm type lifting mechanism or the like) can be used as the lifting mechanism.

  Further, as shown in FIG. 1, the power window unit 10 includes a power window ECU 12, an operation switch 13, and a power window rotation detection sensor 14. The operation switch 13 corresponds to an operation unit in the present embodiment, and is operated by an occupant (user) of the vehicle to open and close the window glass. The power window ECU 12 corresponds to a control unit in the present embodiment, and strictly corresponds to a first control unit that controls the power window motor 11. As shown in FIG. 1, the power window ECU 12 includes a microcomputer 15, a motor drive circuit 16, an input circuit 17, an output circuit 18, and a communication interface 19 (denoted as communication I/F in the drawing).

  The microcomputer 15 forms the center of the power window ECU 12, and is activated by application of the power supply voltage stepped down by the 5V power supply circuit 20. In addition, the microcomputer 15 is communicatively connected to the main body ECU 50 via a communication interface 19 by a LIN (Local Internet Network) method.

  Further, the microcomputer 15 receives a signal (command signal) output from the operation switch 13 through the input circuit 17. Further, when the microcomputer 15 receives the command signal, it outputs a signal (command signal) in conjunction with this. The command signal is transmitted to the operation switch 13 through the output circuit 18 and received by the operation switch 13. When the operation switch 13 receives the command signal, the LED 13d incorporated in the switch emits light.

  Further, the microcomputer 15 switches the energization state of the motor drive circuit 16 according to the command signal received from the operation switch 13. As a result, the power window motor 11 is controlled. Specifically, the motor drive circuit 16 is arranged between the power source and the power window motor 11. A relay switch (not shown) is built in the motor drive circuit 16, and the energization state of the motor drive circuit 16 is switched by turning on/off the relay switch.

  When the microcomputer 15 receives the drive signal output from the operation switch 13, the microcomputer 15 turns on the relay switch and switches the motor drive circuit 16 to the energization on state. As a result, the power window motor 11 is driven to rotate.

  More specifically, the operation switch 13 according to the present embodiment is configured by a swing type switch that can be operated in two steps, and includes a close switch 13a, an open switch 13b, and an auto switch 13c. For example, when one end of the operation switch 13 is operated by one step, the closing switch 13a is turned on. As a result, a normally closed signal as a command signal is output from the operation switch 13. Upon receiving the normally closed signal, the microcomputer 15 rotates the power window motor 11 only during the time when the normally closed signal is received. As a result, the window glass is normally closed (moved up while the switch is being operated).

  When one end of the operation switch 13 is operated in two steps, the auto switch 13c is turned on together with the closing switch 13a. As a result, an automatic closing signal as a command signal is output from the operation switch 13. Upon receipt of the auto-close signal, the microcomputer 15 continuously rotates the power window motor 11 until the window glass reaches the fully closed position. As a result, the window glass comes to perform an automatic closing operation (an operation of continuously rising even after the switch operation is stopped).

  When the other end of the operation switch 13 is operated by one step, the open switch 13b is turned on. As a result, a normally open signal as a command signal is output from the operation switch 13. Upon receiving the normally open signal, the microcomputer 15 rotates the power window motor 11 only during the time when the normally open signal is received. As a result, the window glass is normally opened (moved only while the switch is being operated).

  Further, when the other end of the operation switch 13 is stepped in two stages, the open switch 13b and the auto switch 13c are turned on. As a result, the automatic opening signal as a command signal is output from the operation switch 13. Upon receiving the automatic open signal, the microcomputer 15 continuously rotates the power window motor 11 until the window glass reaches the fully open position. As a result, the window glass will perform an automatic opening operation (an operation that continues to descend even after the switch operation is stopped).

  Incidentally, the microcomputer 15 has a function of controlling the rotation speed of the power window motor 11 (in other words, the movement speed of the window glass) according to the situation during the period when the power window motor 11 is rotating. More specifically, the microcomputer 15 turns on/off the relay switch in the motor drive circuit 16 according to the set duty ratio to apply the voltage (output voltage) applied to the power window motor 11 by the pulse width modulation method. Control. As a result, the rotation speed of the power window motor 11 is controlled to a speed according to the duty ratio.

  By the way, the power window ECU 12 (strictly speaking, the microcomputer 15) controls the power window motor 11 based on the command signal received from the operation switch 13, and also controls the rotation state of the power window motor 11 and the current state of the window glass. It has a function to specify the position. More specifically, the microcomputer 15 periodically receives a pulse signal from the power window rotation detection sensor 14 while the power window motor 11 is rotating. The power window rotation detection sensor 14 corresponds to the first pulse signal output device in the present embodiment, and is configured by, for example, a Hall element. Then, the power window rotation detection sensor 14 outputs a pulse signal every time the power window motor 11 rotates by a unit rotational speed (specifically, one rotation). In other words, the pulse signal is output each time the window glass moves a distance corresponding to one rotation of the power window motor 11.

  The microcomputer 15 receives the pulse signal output from the power window rotation detection sensor 14, and calculates the rotation state of the power window motor 11, more specifically, the rotation speed, from the reception interval. Explaining the procedure for calculating the rotation speed, the microcomputer 15 identifies the waveform of the received pulse signal and detects the rising portion or falling portion of the waveform, that is, the pulse edge. Then, the microcomputer 15 calculates the rotation speed of the power window motor 11 from the pulse edge interval. Further, at this time, the microcomputer 15 determines the rotation direction of the power window motor 11 from the phase difference between the pulse signals.

  Further, the microcomputer 15 identifies the direction in which the window glass is moving, based on the determined rotation direction of the power window motor 11. Furthermore, the microcomputer 15 identifies the current position of the window glass in the moving range of the window glass by counting the pulse edges of the received pulse signal. Explaining the procedure for specifying the current position of the window glass, first, the pulse edge count number at the reference position (for example, the fully closed position) in the moving range of the window glass is set to 0 (zero). On the other hand, the microcomputer 15 stores in the internal memory 15a data indicating the correspondence between the pulse edge count and the distance from the reference position.

  Then, when the count number of the pulse edge increases or decreases in conjunction with the rotation of the power window motor 11, the microcomputer 15 determines the position corresponding to the current count number based on the above correspondence, that is, the current position of the window glass. (Distance from the reference position) is specified. Incidentally, the pulse edge count number corresponds to the pulse signal count number output from the power window rotation detection sensor 14.

  Next, the configuration of the sunshade drive unit 30 will be described. The sunshade drive unit 30 is a part of the device 1 that controls opening/closing movement of the sunshade. The sunshade drive unit 30 includes a motor (hereinafter, sunshade drive motor 31) as a drive source and an elevating mechanism (not shown) for elevating the sunshade. The sun shade driving motor 31 corresponds to the second motor in the present embodiment, and is rotationally driven to open and close the sun shade. The elevating mechanism moves up and down (opens and closes) the sun shade by operating using the rotational force of the sun shade drive motor 31. Note that, although a description of the specific configuration of the lifting mechanism is omitted, a known mechanism (for example, an X-arm type lifting mechanism or the like) can be used as the lifting mechanism.

  Further, the sunshade drive unit 30 includes a sunshade drive ECU 32 and a sunshade drive rotation detection sensor 33, as shown in FIG. 1. The sun shade driving ECU 32 corresponds to the second control unit in the present embodiment. As shown in FIG. 1, the sun shade driving ECU 32 includes a microcomputer 34, a motor driving circuit 35, and a communication interface 36 (denoted as communication I/F in the drawing).

  The microcomputer 34 forms the center of the sunshade driving ECU 32 and is activated by application of the power supply voltage stepped down by the 5V power supply circuit 37. Further, the microcomputer 34 is communicatively connected to the main body ECU 50 via a communication interface 36 in a CAN (Controller Area Network) system. Therefore, the microcomputer 34 of the sunshade driving ECU 32 can transmit/receive data to/from the power window ECU 12 via the main body ECU 50.

  More specifically, when the microcomputer 15 of the power window ECU 12 receives the command signal from the operation switch 13, the microcomputer 15 outputs a similar command signal to the sunshade driving ECU 32 in a linked manner. When the output signal is transmitted from the power window ECU 12 through the communication interface 19, the output signal is transmitted to the main body ECU 50 by the LIN method. After that, the main body ECU 50 transmits the received signal to the sunshade driving ECU 32. The signal transmitted from the main body ECU 50 is transmitted to the sunshade driving ECU 32 by the CAN method, and finally received by the microcomputer 34 of the sunshade driving ECU 32.

  Further, the microcomputer 34 switches the energization state of the motor drive circuit 35 according to a signal (command signal) received from the power window ECU 12 through the vehicle-mounted network. As a result, the sun shade drive motor 31 is controlled. Note that the configuration and operation example of the motor drive circuit 35 are the same as those of the motor drive circuit 16 provided in the power window ECU 12, and thus description thereof will be omitted.

  The control of the sunshade drive motor 31 will be described in detail. When the microcomputer 34 rotates the sunshade drive motor 31 in response to a command signal received from the power window ECU 12, the sunshade moves in the same direction as the window glass. The sun shade driving motor 31 is rotated.

  Specifically, when the microcomputer 15 of the power window ECU 12 receives the automatic close signal from the operation switch 13, the microcomputer 34 of the sunshade driving ECU 32 also receives the automatic close signal. As a result, the sun shade drive motor 31 rotates until the sun shade reaches the fully closed position, and the sun shade performs the automatic closing operation. Similarly, when the microcomputer 15 of the power window ECU 12 receives the automatic open signal from the operation switch 13, the microcomputer 34 of the sunshade driving ECU 32 also receives the automatic open signal. As a result, the sun shade drive motor 31 rotates until the sun shade reaches the fully open position, and the sun shade performs the automatic opening operation.

  As described above, in the present embodiment, when the occupant of the vehicle operates the operation switch 13 to open and close the window glass, the sunshade interlocks and moves in the same direction as the window glass. That is, in this embodiment, when the operation switch 13 is operated, both the window glass and the sunshade simultaneously move in the same direction. More specifically, when the microcomputer 15 of the power window ECU 12 receives a command signal from the operation switch 13 and starts rotating the power window motor 11, the microcomputer 34 of the sunshade driving ECU 32 operates in conjunction with this. The sun shade driving motor 31 is rotated.

  By the way, the sun shade drive ECU 32 (strictly speaking, the microcomputer 34) has a function of specifying the rotation state of the sun shade drive motor 31 and the current position of the sun shade while the sun shade drive motor 31 is rotating. More specifically, the microcomputer 34 periodically receives a pulse signal from the sunshade drive rotation detection sensor 33 while the sunshade drive motor 31 is rotating. The sunshade drive rotation detection sensor 33 corresponds to a signal output device in the present embodiment, and strictly corresponds to a second pulse signal output device. The sunshade drive rotation detection sensor 33 is composed of, for example, a Hall element, and outputs a pulse signal every time the sunshade drive motor 31 rotates by a unit rotational speed (specifically, one rotation). In other words, the pulse signal is output every time the sunshade moves a distance corresponding to one rotation of the sunshade driving motor 31.

  The microcomputer 34 receives the pulse signal output from the sun shade drive rotation detection sensor 33, and calculates the rotation state of the sun shade drive motor 31, more specifically, the rotation speed, from the reception interval. The procedure of calculating the rotation speed is the same as the procedure described above, and thus the description thereof will be omitted. Further, when calculating the rotation speed of the sun shade drive motor 31, the microcomputer 34 determines the rotation direction thereof. Further, the microcomputer 34 identifies the direction in which the sunshade is moving, based on the rotation direction of the sunshade drive motor 31.

  Furthermore, the microcomputer 34 identifies the current position of the sun shade in the movement range of the sun shade by counting the pulse edges of the pulse signal received from the sun shade driving rotation detection sensor 33. The procedure for specifying the current position of the sunshade is similar to the procedure for specifying the current position of the window glass. That is, the microcomputer 34 stores in the internal memory 34a data indicating the correspondence relationship between the pulse edge count and the distance from the reference position. Then, when the count number of the pulse edge increases or decreases in conjunction with the rotation of the sun shade drive motor 31, the microcomputer 34, based on the above correspondence, the position corresponding to the current count number, that is, the current position of the sun shade ( Distance from the reference position).

  Here, the number of pulse edges (the number of counts) counted by the microcomputer 34 of the sunshade drive ECU 32 corresponds to the number of pulse signals output from the sunshade drive rotation detection sensor 33. The pulse edge count number is used to identify the current position of the sunshade as described above, and thus can be said to be an index indicating the current position of the sunshade.

  Further, in the present embodiment, the microcomputer 34 of the sunshade driving ECU 32 generates data indicating the pulse edge count number and transmits the data to the power window ECU 12 via the main body ECU 50. Upon receiving the above data, the microcomputer 15 of the power window ECU 12 controls the power window motor 11 based on the pulse edge count number indicated by the data. More specifically, the microcomputer 15 of the power window ECU 12 acquires the pulse edge count number counted on the sunshade drive ECU 32 side so that the window glass moves at a moving speed corresponding to the count number. Then, the power window motor 11 is controlled.

  Here, the count number of pulse edges counted on the sunshade driving ECU 32 side is an index indicating the current position of the sunshade, as described above. That is, in this embodiment, the window glass driving motor (that is, the power window motor 11) is controlled according to the current position of the sunshade. Thereby, when both the window glass and the sunshade are simultaneously moved in the same direction, the both can be appropriately moved. Such a configuration is a feature of this embodiment, and the characteristic configuration will be described below with reference to FIGS. 2 and 3.

  The following description will be made assuming a case where an automatic opening signal is output from the operation switch 13, that is, a case where both the window glass and the sunshade continue to move until they reach the fully opened position. More specifically, the case where the window glass and the sunshade move from the fully closed position to the fully open position will be described below as an example.

  Upon receiving the auto open signal from the operation switch 13, the microcomputer 15 of the power window ECU 12 turns on a relay switch in the motor drive circuit 16 to rotate the power window motor 11. As a result, the window glass is lowered, and the position of the window glass is gradually displaced toward the fully open position as shown in FIG. The curve C1 in FIG. 3 shows the change over time of the position of the window glass (change over time from the time when the operation switch 13 is operated).

  Incidentally, when rotating the power window motor 11, a power supply voltage is applied to the power window motor 11, but a relatively high starting voltage is applied immediately after the start of rotation. Thereafter, as a result of being controlled by the power window ECU 12, the voltage applied to the power window motor 11 changes according to the behavior indicated by the curve C3 in FIG. The control pattern of the voltage applied to the power window motor 11 will be described in detail later.

  When a predetermined time has elapsed from the start of rotation of the power window motor 11, the microcomputer 15 of the power window ECU 12 outputs an auto open signal to the sunshade drive ECU 32 via the main body ECU 50. When the microcomputer 34 of the sun shade driving ECU 32 receives the auto open signal via the main body ECU 50, it turns on the relay switch of the motor driving circuit 35 to rotate the sun shade driving motor 31. As a result, the sunshade descends, and the position of the sunshade is gradually displaced toward the fully open position as shown in FIG. The curve C2 in FIG. 3 indicates the change over time of the position of the sunshade (change over time from the time when the operation switch 13 is operated).

  Incidentally, when the sun shade driving motor 31 is rotated, a power supply voltage is applied to the sun shade driving motor 31, but the magnitude of the applied voltage changes in a rectangular wave shape as shown in FIG. That is, the voltage applied to the sunshade drive motor 31 is maintained at a constant magnitude from the time when the motor starts to rotate to the time when the motor ends. The curve C4 in FIG. 3 shows the change over time in the voltage applied to the sunshade drive motor 31 (change over time from the time when the operation switch 13 is operated).

  By the way, the microcomputer 15 of the power window ECU 12 receives a pulse signal from the power window rotation detection sensor 14 each time the power window motor 11 makes one revolution while the power window motor 11 is rotating. Each time the microcomputer 15 receives a pulse signal from the power window rotation detection sensor 14, the microcomputer 15 counts the pulse edge thereof (S001 in FIG. 2). At this time, the microcomputer 15 identifies the current position of the window glass based on the pulse edge count number.

  On the other hand, the microcomputer 34 of the sun shade drive ECU 32 receives a pulse signal from the sun shade drive rotation detection sensor 33 each time the sun shade drive motor 31 makes one revolution while the sun shade drive motor 31 is rotating. Each time the microcomputer 34 receives a pulse signal from the sun shade drive rotation detection sensor 33, the microcomputer 34 counts the pulse edge thereof. The microcomputer 34 also generates data indicating the pulse edge count number and outputs the data to the power window ECU 12 via the main body ECU 50. The microcomputer 15 of the power window ECU 12 receives the above-mentioned data via the main body ECU 50 to obtain the number of pulse edges counted on the sunshade drive ECU 32 side (S002 in FIG. 2).

  Further, the microcomputer 15 of the power window ECU 12 periodically executes the difference calculation process while the power window motor 11 is rotating (S003 in FIG. 2). The difference calculation process is the difference between the pulse edge count number (hereinafter, P1) counted on the power window ECU 12 side and the pulse edge count number (hereinafter, P2) counted on the sunshade drive ECU 32 side, that is, , P1-P2.

  When the above difference (P1-P2) is captured, the fact that the difference is positive means that the current position of the window glass is closer to the fully open position than the current position of the sunshade. On the contrary, the negative difference means that the current position of the window glass is farther from the fully opened position than the current position of the sunshade.

  Then, the microcomputer 15 of the power window ECU 12 changes the magnitude of the voltage applied to the power window motor 11, specifically, the duty ratio, according to the above difference, thereby changing the rotation speed of the power window motor 11. It is controlled (S004 in FIG. 2). As a result, the window glass moves at the moving speed according to the difference.

  Here, the setting rule of the duty ratio will be described with reference to FIG. 2. When the difference is positive, the duty ratio is set to 50% (S005 in FIG. 2). If the difference is negative and the absolute value thereof exceeds the threshold value, the duty ratio is set to 100% (S006 in FIG. 2). Further, when the difference is negative and the absolute value is equal to or less than the threshold value, the duty ratio is set to a variable value, and specifically, the duty ratio is appropriately changed according to the difference (S007 in FIG. 2).

  A situation in which the power window motor 11 is actually controlled by applying the above setting rules will be described with reference to FIG. 3. A period immediately after the power window motor 11 starts rotating (indicated by a symbol X1 in the figure). During the period shown), the power supply voltage is applied to the power window motor 11 at a duty ratio of 100% regardless of the position of the sunshade.

  After the lapse of the period X1, only the window glass moves (descends) toward the fully open position for a while, and then the sunshade driving motor 31 starts to rotate and the window glass and the sunshade simultaneously descend. The above difference is positive for some time (the period indicated by the symbol X2 in FIG. 3) after the sunshade starts to move after the period X1 has elapsed. Therefore, during the period X2, the microcomputer 15 of the power window ECU 12 changes the duty ratio to 50% and applies the power supply voltage to the power window motor 11. As a result, the moving speed of the window glass during the period X2 becomes lower than the moving speed during the period X1, and strictly speaking, it becomes slightly lower than the moving speed of the sunshade.

  As a result, some time after the sunshade starts moving, the current position of the sunshade comes closer to the fully open position than the current position of the window glass. After this time, until the window glass reaches the fully open position, the microcomputer 15 of the power window ECU 12 monitors the difference in the pulse edge count numbers from time to time and controls the power window motor 11 according to the difference ( S008 in FIG. 2).

  More specifically, from the time when the current position of the sunshade exceeds the current position of the window glass for a while (the period indicated by symbol X3 in FIG. 3), the above difference becomes negative and its absolute value is It is less than or equal to the threshold. Therefore, in the period X3, the microcomputer 15 of the power window ECU 12 applies the power supply voltage to the power window motor 11 while changing the duty ratio to a variable value and appropriately changing the duty ratio according to the difference. As a result, in the same period X3, the window glass moves (falls) at a moving speed slightly lower than the moving speed of the sunshade. Therefore, during the period X3, the window glass moves (descends) while maintaining the current position thereof farther from the fully open position than the current position of the sunshade.

  Further, in the period from the lapse of the period X3 until the sunshade reaches the fully opened position (the period indicated by the symbol X4 in FIG. 3), the above difference becomes negative and its absolute value exceeds the threshold value. Therefore, during the period X4, the microcomputer 15 of the power window ECU 12 sets the duty ratio to 100% and applies the power supply voltage to the power window motor 11. As a result, in the same period X4, the window glass moves (falls) at the movement speed of the sunshade and substantially the movement speed. For this reason, during the period X4, the window glass continues to move (descends) while continuing the period X3 while keeping the current position thereof farther from the fully open position than the current position of the sunshade.

  Then, in the period after the period X4 (the period indicated by the symbol X5 in FIG. 3), the duty ratio is gradually reduced until the window glass reaches the fully opened position. Then, the microcomputer 15 of the power window ECU 12 stops the power window motor 11 when the window glass reaches the fully opened position (S009, S010 in FIG. 2), and performs one automatic opening operation at that time. The motor control flow ends.

  By the control described above, in the present embodiment, during the period in which both the window glass and the sunshade are simultaneously lowered toward the fully open position (strictly, between the periods X3, X4, and X5), the window glass The current position moves (descends) at a moving speed that allows the current position of the sunshade to be kept away from the fully open position. This makes it possible to prevent the sunshade located on the passenger compartment side from being exposed to the outside air while being exposed.

  More specifically, in a configuration in which the window glass reaches the fully opened position first and the sunshade reaches the fully opened position after a while, the sunshade is exposed to the outside air, and in particular, it may be agitated by the wind during strong wind. is there. On the other hand, in the present embodiment, by controlling the moving speed of the window glass according to the current position of the sunshade, the sunshade reaches the fully open position first, and as a result, the sunshade is exposed to the outside air. It is possible to avoid the situation that happens.

  As described above, in the present embodiment, when both the window glass and the sunshade are simultaneously moved in the same direction, a situation in which the window glass and the sunshade are largely separated from each other is avoided, and the windows are smoothly opened and closed. As a result, the device 1 becomes convenient for the user.

  Although the opening/closing control member of the present invention has been described above with reference to an example, the above embodiment is merely an example, and other examples are possible. For example, in the above embodiment, the device for opening and closing the window glass and the sunshade provided on the vehicle door has been described, but the present invention is also applicable to devices for opening and closing the opening and closing members other than the above. For example, a device for controlling opening/closing movement of a window glass and a sunshade provided on a vehicle other than a vehicle, a device for controlling opening/closing movement of an inner slide door and an outer slide door provided on a vehicle side, and a device arranged on a ceiling of a vehicle. The present invention also relates to a device for controlling the opening/closing movement of a sunroof and a sunshade, or a device for controlling the opening/closing movement of two opening/closing members that are arranged close to each other in an object other than a vehicle (for example, a building or equipment). Is applicable.

  Further, in the above embodiment, only the motor that is rotationally driven to open and close the window glass (that is, the power window motor 11) is controlled, but the invention is not limited to this. A motor that is rotationally driven to open and close the sunshade (that is, the sunshade driving motor 31) may also be controlled.

  In the above embodiment, the count number of pulse signals (strictly speaking, the pulse edge count number) output from the sunshade drive rotation detection sensor 33 is used as an index indicating the current position of the sunshade. However, the present invention is not limited to this, as long as it indicates the current position of the sunshade, for example, when the rotation time of the sunshade drive motor 31 or the current position of the sunshade (distance from the reference position) is measured. You may use the measurement result of.
