Description

  The present invention relates to an automobile window opening / closing device mounted on an automobile for opening / closing a window, and a control device used therefor.

  An operation switch for opening and closing the window is provided beside the driver's seat of the automobile. In addition to the switch for opening and closing the driver's seat window, the operation switch includes a switch for opening and closing the passenger seat and rear seat windows. In addition, operation switches for opening and closing the windows of the respective seats are provided beside the passenger seat and the rear seat.

  By the way, an infant or the like in the passenger seat or the rear seat may erroneously press an operation switch provided on the side of each seat. In this case, if the switch is kept pressed, the window W of the car C opens widely as shown in FIG. 38A, and there is a risk that an infant or the like falls outside the opened window. Therefore, in order to prevent the window from being opened due to an erroneous operation, a window opening / closing prohibiting switch for prohibiting opening / closing of the windows of the passenger seat and the rear seat is provided in addition to the operation switch beside the driver's seat. When this window opening / closing prohibition switch is operated, the windows of the passenger seat and the rear seat cannot be opened and closed even if the operation switch beside the passenger seat or the rear seat is operated. This prevents inadvertent opening of the window and ensures safety. Such a window opening / closing prohibition switch is described in, for example, Patent Document 1 described later.

  On the other hand, when the car window has been closed for a long time and the air in the car has stagnated or the air in the car has become dirty due to smoking, etc., the window W is slightly opened as shown in FIG. Sometimes you want to change the air in the car. In such a case, Patent Documents 2 to 5 below describe window opening / closing control devices that can slightly open a window by a predetermined operation.

When the other window opening / closing restriction switch is operated and the other window opening operation is performed, the control device does not detect that the other seat window has been opened by a predetermined amount by the sensor. The opening operation of the window is allowed, and the opening operation of the window is stopped when it is detected that the window of the other seat is opened by a predetermined amount.

  Further, the control device according to the present invention includes an output signal from the driver's seat other window operation switch for opening / closing the window of the other seats other than the driver's seat, or the other seat operation switch for opening / closing the window of the other seat. Based on the output signal from the other seat, the window of the other seat is controlled based on the output signal from the other window opening / closing restriction switch for the driver's seat for controlling the opening / closing of the window of the other seat and restricting the opening / closing of the window of the other seat. A control device that restricts opening and closing, and when the other window opening operation is performed while the other window opening and closing restriction switch is activated, the opening operation of the window is continued until a predetermined amount of the other seat window is opened. And a control unit that stops the opening operation of the window of the other seat when the window of the other seat is opened by a predetermined amount.

  In the automotive window opening / closing device and control device of the present invention, even when the other window opening / closing restriction switch is turned on, ventilation can be performed by slightly opening the window, and the window opens only in a limited amount. Therefore, there is no risk that an infant or the like falls, and safety is ensured.

  In a preferred embodiment of the present invention, the control unit of the control device is configured so that when the other window operation switch for the driver's seat is operated to open / close the window of the other seat while the other window opening / closing restriction switch is operated, Control based on the operation of the window open / close limit switch is prohibited. According to this, even if the other window opening / closing restriction switch is turned on, the other window opening / closing restriction can be released by the driver's seat other window operation switch.

  Further, in a preferred embodiment of the present invention, the controller of the control device opens the other-seat window when the other-window opening / closing restriction switch is operated and the other-seat window is closed. The window closing operation is allowed only when is within a certain range, and when the opening amount of the window of the other seat is not within the certain range, the window closing operation is prohibited. According to this, since a certain restriction is applied to the closing operation of the window of the other seat, it is possible to avoid a risk that the arm, the neck, or the like is pinched by the window glass when the window is closed.

  According to the present invention, it is possible to prevent the windows of seats other than the driver's seat from being greatly opened by operating the other window open / close restriction switch, and to open a certain amount of windows even if the switch is operated. It is possible to ventilate by slightly opening the window while ensuring safety.

Become. By operating the passenger seat switch 4a, the passenger seat window 101b can be opened and closed. By operating the rear left seat switch 4b, the rear left seat window 101c can be opened and closed. The rear right seat window 101d can be opened and closed by operating the rear right seat switch 4c.

  Of the above switches, the driver's seat operation switch 1, the driver's seat other window operation switch 2, and the other seat operation switch 4 are, as shown in FIG. It has a contact structure that can be switched to three positions: side and neutral. Further, the other window opening / closing restriction switch 3 has a normal contact configuration as shown in FIG.

  Reference numeral 5 denotes a sensor (hereinafter referred to as “window position detection sensor”) that detects the amount of opening of the window based on the raising / lowering position of the window glass, and a rotary encoder attached to each of the window motors 10 and 12 to 14 described later. The signal processing circuit counts and processes the pulse signals output from the rotary encoder. As the window position detection sensor 5, instead of the rotary encoder and the signal processing circuit, microswitches or photosensors provided at a plurality of positions in each window can be used.

  Reference numeral 10 denotes a driver's seat window motor for opening and closing the driver's seat window 101a, and 11 is a passenger's seat window motor for opening and closing windows of seats other than the driver's seat. The driver seat window motor 10 is driven by the operation of the driver seat operation switch 1. The other seat window motor 11 opens and closes a passenger seat window motor 12 that opens and closes a passenger seat window 101b, a rear left seat window motor 13 that opens and closes a rear left seat window 101c, and a rear right seat window 101d. And a rear right seat window motor 14. The passenger seat window motor 12 is driven by the operation of the passenger seat switch 4a. The rear left seat window motor 13 is driven by the operation of the rear left seat switch 4b. The rear right seat window motor 14 is driven by operating the rear right seat switch 4c.

  A control unit 15 controls the overall operation of the automobile window opening / closing device A, and includes a microprocessor (CPU), an input / output interface, a motor control circuit, and the like. Reference numeral 16 denotes a memory, which includes a RAM, a ROM, and the like. The control unit 15 and the memory 16 constitute a control device of the present invention.

  FIG. 4 is a diagram illustrating an example of a window opening / closing mechanism provided for each of the windows 101a to 101d. Reference numeral 100 denotes an automobile window, 101 denotes a window glass for opening and closing the window 100, and 102 denotes a window opening / closing mechanism. Since the opening / closing mechanism of each window is the same, the symbol of the window is represented by 100 in FIG. The window glass 101 moves up and down by the operation of the window opening / closing mechanism 102, the window 100 is closed when the window glass 101 is raised, and the window 100 is opened when the window glass 101 is lowered.

  In the window opening / closing mechanism 102, 103 is a support member attached to the lower end of the window glass 101. 104 is a first arm whose one end is engaged with the support member 103, and the other end is rotatably supported by the bracket 106. 105 is one end engaged with the support member 103, and the other end is engaged with the guide member 107. Second arm. Reference numeral 108 denotes a window motor which comprises the driver seat window motor 10 or the other seat window motor 11 shown in FIG. Reference numeral 109 denotes a pinion that is rotationally driven by the window motor 108, and 110 denotes a fan-shaped gear that meshes with the pinion 109 and rotates. The gear 110 is fixed to the first arm 104. Reference numeral 111 denotes a rotary encoder that constitutes the window position detection sensor 5 described above, and is connected to the rotation shaft of the window motor 108. The rotary encoder 111 outputs a number of pulse signals proportional to the amount of rotation of the window motor 108. The opening amount of the window 100 is calculated by counting the pulse signal by a signal processing circuit (not shown), and the signal processing circuit outputs a detection signal when the opening amount reaches a certain value.

  The window motor 108 can rotate in the forward and reverse directions, and the pinion 109 and the gear 110 are rotated by the rotation in the forward and reverse directions to rotate the first arm 104 in the forward and reverse directions. Following this, the other end of the second arm 105 slides laterally along the groove of the guide member 107, and the support member 103 moves up and down to raise and lower the window glass 101, thereby opening and closing the window 100. . The window opening / closing mechanism 102 as described above is known and disclosed in, for example, the above-mentioned Patent Document 5.

  FIG. 5 shows a control circuit for performing opening / closing control of the window 100. This control circuit includes a logic circuit as hardware, but it goes without saying that the logic circuit portion can be realized by software in the control unit 15 (FIG. 1). The same applies to the subsequent logic circuits. 2 is a driver's seat other window operation switch, 3 is an other window opening / closing restriction switch, 4 is an other seat operation switch, 5 is a window position detection sensor, and 11 is an other seat window motor, which are shown in FIG. It is the same as that. 21 and 22 are AND gates, and 23 and 24 are OR gates. One input of the AND gate 22 is an inverting input. As described above, the window position detection sensor 5 includes the rotary encoder 111 (FIG. 4) and a signal processing circuit (not shown). In FIG. 5, for convenience of explanation, the window position detection sensor 5 is illustrated as a switch. is there. The window position detection sensor 5 is turned on and outputs a detection signal when the opening amount of the window exceeds a predetermined amount.

  Next, window opening / closing control by the control circuit of FIG. 5 will be described. First, the operation when the other window opening / closing restriction switch 3 is not operated will be described.

  FIG. 6 shows a case where the other-seat operation switch 4 is operated to the “open” side (when the window is opened) in a state where the other window opening / closing restriction switch 3 is not operating (off state). In this case, the output of the other window opening / closing restriction switch 3 is L (Low), the “open” side output of the other seat operation switch 4 is H (High), and the “close” side output of the other seat operation switch 4 is L. It becomes. Since the window position detection sensor 5 is not yet operated, its output is L. Further, since the driver's seat other window operation switch 2 is not operated, the “open” side output and the “closed” side output are both L. Therefore, the states of H and L at the input / output of each gate 21 to 24 are as shown in FIG.

  In FIG. 6, the inputs of the AND gate 21 are both L, and the output of the AND gate 21 is L. The L signal is applied to the inverting input terminal of the AND gate 22, and the H signal is applied to the other input terminal of the AND gate 22 from the other-seat operation switch 4. As a result, the output of the AND gate 22 becomes H, and the output of the OR gate 24 becomes H, and the other-seat window motor 11 is driven to open the window by this H signal. When the motor 11 is driven, the window opening / closing mechanism 102 shown in FIG. 4 is operated, the window glass 101 is lowered, and the window 100 is opened. Then, when a certain time has elapsed, the window position detection sensor 5 detects that the window opening amount X has reached the predetermined amount Y, and an H signal is output from the window position detection sensor 5 as shown in FIG. . For this reason, one input of the AND gate 21 becomes H, but the other input remains L. Therefore, the output of the AND gate 21 does not change with L, and the other-seat operation switch 4 is on the “open” side. While being pushed, the driving of the window motor 11 for other seats is continued and the window 100 continues to open. When the pressing of the other-seat operation switch 4 is released, the switch 4 returns to the neutral position, the output of the AND gate 22 becomes L, the output of the OR gate 24 becomes L, and the other-seat window motor 11 stops.

  FIG. 8 shows a case where the other-seat operation switch 4 is operated to the “closed” side (when the window is closed) in a state where the other window opening / closing restriction switch 3 is not operating (off state). In this case, the output of the other window opening / closing restriction switch 3 is L, the “open” side output of the other seat operation switch 4 is L, and the “close” side output of the other seat operation switch 4 is H. If the window is opened by a predetermined amount Y or more, the output of the window position detection sensor 5 is H. Further, since the driver's seat other window operation switch 2 is not operated, the “open” side output and the “closed” side output are both L. Therefore, the states of H and L at the input / output of each gate 21 to 24 are as shown in FIG.

  In FIG. 8, since the input of the AND gate 21 is L and H, the output of the AND gate 21 is L. This L signal is given to the inverting input terminal of the AND gate 22, and the L signal is given to the other input terminal of the AND gate 22 from the other-seat operation switch 4. As a result, the output of the AND gate 22 is L, and the output of the OR gate 24 is L. On the other hand, as a result of the H signal being given to the OR gate 23 from the other-seat operation switch 4, the output of the OR gate 23 becomes H, and the other-seat window motor 11 is driven in the direction of closing the window by this H signal. When the motor 11 is driven, the window opening / closing mechanism 102 shown in FIG. 4 is activated, the window glass 101 is raised, and the window 100 is closed. Then, when a certain period of time has elapsed, the window opening amount X becomes smaller than the predetermined amount Y, so that an L signal is output from the window position detection sensor 5 as shown in FIG. Therefore, both inputs of the AND gate 21 become L, but the output of the AND gate 21 does not change at L, and the other seat window is maintained while the other seat operation switch 4 is pushed to the “closed” side. The drive of the motor 11 is continued and the window 100 is kept closed. When the pressing of the other-seat operation switch 4 is released, the switch 4 returns to the neutral position, the output of the OR gate 23 becomes L, and the other-seat window motor 11 stops.

  Therefore, when the other window opening / closing restriction switch 3 is not operating, the window is opened regardless of the detection operation of the window position detection sensor 5 while the other-seat operation switch 4 is pushed to the “open” side. As long as the other-seat operation switch 4 is pushed to the “closed” side, the window is closed regardless of the detection operation of the window position detection sensor 5. As a result, the window 100 can be freely moved between the state where the window 100 as shown in FIG. 10 is completely closed and the state where the window 100 as shown in FIG. Can be opened and closed.

  Next, the operation when the other window opening / closing restriction switch 3 is operated will be described.

  FIG. 12 shows a case where the other-seat operation switch 4 is operated to the “open” side (when the window is opened) in a state where the other window opening / closing restriction switch 3 is operated (on state). In this case, the output of the other window opening / closing restriction switch 3 is H, the “open” side output of the other seat operation switch 4 is H, and the “close” side output of the other seat operation switch 4 is L. Further, since the window position detection sensor 5 does not operate at first, its output becomes L. Further, since the driver's seat other window operation switch 2 is not operated, the “open” side output and the “closed” side output are both L. Therefore, the states of H and L at the input / output of each gate 21 to 24 are as shown in FIG.

  In FIG. 12, since the input of the AND gate 21 is L and H, the output of the AND gate 21 is L. The L signal is applied to the inverting input terminal of the AND gate 22, and the H signal is applied to the other input terminal of the AND gate 22 from the other-seat operation switch 4. As a result, the output of the AND gate 22 becomes H, and the output of the OR gate 24 becomes H, and the other-seat window motor 11 is driven to open the window by this H signal. When the motor 11 is driven, the window opening / closing mechanism 102 shown in FIG. 4 is operated, the window glass 101 is lowered, and the window 100 is opened. Then, when a certain time has elapsed, the window position detection sensor 5 detects that the window opening amount X has reached a predetermined amount Y, and an H signal is output from the window position detection sensor 5 as shown in FIG. . For this reason, both inputs of the AND gate 21 become H, and the output of the AND gate 21 changes from L to H. As a result, the output of the AND gate 22 changes from H to L, and the output of the OR gate 24 also changes from H to L. Accordingly, since the H signal is not output from the OR gate 24, the passenger seat window motor 11 stops. For this reason, even if the other-seat operation switch 4 is continuously pushed to the “open” side, the window 100 remains open by a predetermined amount Y (= X) as shown in FIG. will not open. The value of Y is set to about 5 to 10 cm, for example.

  FIG. 14 shows a case where the other-seat operation switch 4 is operated to the “closed” side (when the window is closed) in a state where the other window opening / closing restriction switch 3 is operated (ON state). In this case, the output of the other window opening / closing restriction switch 3 is H, the “open” side output of the other seat operation switch 4 is L, and the “closed” side output of the other seat operation switch 4 is H. If the window is opened by a predetermined amount Y or more, the output of the window position detection sensor 5 is H. Further, since the driver's seat other window operation switch 2 is not operated, the “open” side output and the “closed” side output are both L. Therefore, the states of H and L at the input / output of each gate 21 to 24 are as shown in FIG.

  In FIG. 14, the inputs of the AND gate 21 are both H, and the output of the AND gate 21 is H. The H signal is applied to the inverting input terminal of the AND gate 22, and the L signal is applied to the other input terminal of the AND gate 22 from the other-seat operation switch 4. As a result, the output of the AND gate 22 is L, and the output of the OR gate 24 is L. On the other hand, as a result of the H signal being given to the OR gate 23 from the other-seat operation switch 4, the output of the OR gate 23 becomes H, and the other-seat window motor 11 is driven in the direction of closing the window by this H signal. When the motor 11 is driven, the window opening / closing mechanism 102 shown in FIG. 4 is activated, the window glass 101 is raised, and the window 100 is closed. Then, when a certain time has elapsed, the window opening amount X becomes smaller than the predetermined amount Y, so that the L signal is output from the window position detection sensor 5 as shown in FIG. Therefore, one input of the AND gate 21 becomes L, and the output of the AND gate 21 becomes L. However, since the output of the AND gate 22 does not change with L, the other-seat operation switch 4 is pushed to the “closed” side. While this is being done, the driving of the window motor 11 for the other seats continues and the window 100 continues to close. When the pressing of the other-seat operation switch 4 is released, the switch 4 returns to the neutral position, the output of the OR gate 23 becomes L, and the other-seat window motor 11 stops.

  Therefore, in the state in which the other window opening / closing restriction switch 3 is operated, when the other seat operation switch 4 is pushed to the “open” side, the window 100 is opened until the window opening amount X reaches a predetermined amount Y as shown in FIG. When the window position detection sensor 5 detects that the opening amount X of the window 100 has reached the predetermined amount Y, the opening operation of the window 100 will continue even if the operation switch 4 for the other seats is kept pressed. Stops. Further, when the other seat operation switch 4 is pushed to the “closed” side, the window 100 is closed regardless of the detection operation of the window position detection sensor 5. Therefore, as shown in FIG. 17, the window 100 can be freely opened and closed in a range smaller than Y, but in other ranges, only the window 100 can be closed as shown in FIG. Permissible. In order to enable the opening / closing of the window 100 over the entire range regardless of Y, the other window opening / closing restriction switch 3 may be turned off to cancel the opening / closing restriction operation. Alternatively, as described later, the window 100 can be freely opened and closed by operating the driver's seat other window operation switch 2.

  As described above, in the above-described embodiment, when the other window opening operation is performed while the other window opening / closing restriction switch 3 is operated, the other seat window is opened by a predetermined amount Y. The window opening operation is allowed until the window is detected, and the window opening operation is stopped when it is detected that the window of the other seat is opened by a predetermined amount Y. For this reason, even if the other window opening / closing restriction switch 3 is turned on, ventilation can be performed by slightly opening the window 100 by opening the other-seat operation switch 4. Further, since the window 100 opens only a limited amount Y, there is no possibility that an infant or the like falls from the opened window, and safety can be ensured.

  In the above-described embodiment, the case where the other-seat window is opened and closed by the other-seat operation switch 4 has been described. However, in the case where the other-seat window is opened and closed by the driver-seat other-window operation switch 2, FIG. By the "open" operation of the driver's seat other window operation switch 2, the output of the OR gate 24 is always H, and the other seat window motor 11 is driven in the direction to open the window. Further, by the “close” operation of the driver's seat other window operation switch 2, the output of the OR gate 23 always becomes H, and the other seat window motor 11 is driven in the direction of closing the window. Therefore, by operating the driver's seat other window operation switch 2, the window can be freely opened and closed without limitation regardless of whether the other window opening / closing restriction switch 3 is on or off. Even when the driver's seat other window operation switch 2 is operated, the opening operation of the window is restricted by turning on the other window opening / closing restriction switch 3 in the same manner as when the other seat operation switch 4 is operated. A logic circuit may be configured as described above.

  Further, in the above embodiment, if the other-seat operation switch 4 is continuously pushed to the “closed” side while the other window opening / closing restriction switch 3 is operated, the window 100 reaches the end regardless of the operation of the window position detection sensor 5. Although the window 100 is completely closed, when the opening amount X of the window 100 reaches the predetermined amount Y, the closing operation of the window 100 (the rising of the window glass 101) is performed based on the detection signal of the window position detection sensor 5. The logic circuit may be configured to stop. Thereby, it is possible to prevent an accident such as a finger being caught in the gap of the window.

  FIG. 19 is another embodiment of the present invention, in which when opening / closing the window of the other seat, the operation of the driver's seat other window operation switch 2 is given priority over the operation of the other seat operation switch 4; A control circuit is shown that controls to stop the window motor when the window is fully open and when the window is fully closed.

  Reference numeral 2 is a driver's seat other window operation switch, 3 is an other window opening / closing restriction switch, 4 is an other seat operation switch, and 11 is an other seat window motor, which are the same as those shown in FIG. . The window position detection sensor includes a window position detection sensor 5a that operates when the window is opened by a predetermined amount Y, a window position detection sensor 5b that operates when the window is fully opened, and a window that is completely closed. It consists of the window position detection sensor 5c which operate | moves. 31 to 36 are AND gates, and 37 and 38 are OR gates. One input of the AND gates 32 to 36 is an inverting input.

  Next, window opening / closing control by the control circuit of FIG. 19 will be described. FIG. 20 shows that when the other window opening / closing restriction switch 3 is not operating (OFF state), the other-seat operation switch 4 is operated to the “closed” side, and the other-window operation switch 2 for the driver's seat is set to the “open” side. The case where it operated is shown. In this case, the “open” side output of the driver's seat other window operation switch 2 is H and the “close” side output is L, and the “open” side output of the other seat operation switch 4 is L, “closed”. ”Side output becomes H. The output of the other window opening / closing restriction switch 3 is L. It is assumed that the outputs of the window position detection sensors 5a to 5c are all L. Accordingly, the states of H and L at the input / output of each gate 31 to 38 are as shown in FIG.

  In FIG. 20, even if the other-seat operation switch 4 is operated to the “closed” side, the output of the AND gate 32 is H, because the driver-seat other window operation switch 2 is operated to the “open” side. The output of the AND gate 33 becomes L, whereby the output of the AND gate 35 becomes L and the output of the AND gate 36 becomes H. Therefore, the other seat window motor 11 is driven in the direction to open the window by the H signal from the AND gate 36. That is, the “open” operation of the driver's seat other window operation switch 2 has priority over the “close” operation of the other seat operation switch 4. For this reason, even when the “open” operation of the switch 2 and the “close” operation of the switch 4 are performed at the same time, the operation is not hindered. Then, as shown in FIG. 21, the output of the window position detection sensor 5a becomes H during the process of opening the window (at this time, the output of the AND gate 31 remains L and does not change). Since the output of the position detection sensor 5b becomes H and the output of the AND gate 36 changes to L, the other seat window motor 11 stops. Thereby, the motor 11 can be reliably stopped when the window is completely opened.

  On the other hand, when the other window opening / closing restriction switch 3 is operated (on state), as shown in FIG. 22, the output of the other window opening / closing restriction switch 3 becomes H and when the window is opened by a predetermined amount Y. Since the output of the window position detection sensor 5a is also H, the output of the AND gate 31 is H. As a result, since the output of the AND gate 34 becomes L, the output of the AND gate 36 becomes L, and the other seat window motor 11 stops. At this time, the window is kept open by a predetermined amount Y as shown in FIG. In this way, even when the “open” operation of the driver's seat other window operation switch 2 has priority over the “close” operation of the other seat operation switch 4 and the window is opened, the other window opening / closing restriction switch 3 is turned on. When open, the amount of window opening is limited.

  FIG. 23 shows that when the other window opening / closing restriction switch 3 is not operating (OFF state), the other-seat operation switch 4 is operated to the “open” side, and the other-window operation switch 2 for the driver seat is the “closed” side. The case where it operated is shown. In this case, the “open” side output of the driver's seat other window operation switch 2 is L and the “close” side output is H, and the “open” side output of the other seat operation switch 4 is H, “closed”. ”Side output becomes L. The output of the other window opening / closing restriction switch 3 is L. It is assumed that the outputs of the window position detection sensors 5a to 5c are all L. Therefore, the states of H and L at the input / output of each gate 31 to 38 are as shown in FIG.

  In FIG. 23, even if the other-seat operation switch 4 is operated to the “open” side, the output of the AND gate 32 is L, because the driver-seat other window operation switch 2 is operated to the “closed” side. The output of the AND gate 33 becomes H, whereby the output of the AND gate 35 becomes H and the output of the AND gate 36 becomes L. Therefore, the other seat window motor 11 is driven in the direction of closing the window by the H signal from the AND gate 35. That is, the “close” operation of the driver's seat other window operation switch 2 has priority over the “open” operation of the other seat operation switch 4. For this reason, even when the “close” operation of the switch 2 and the “open” operation of the switch 4 are performed at the same time, the operation is not hindered. When the window is completely closed, as shown in FIG. 24, the output of the window position detection sensor 5c becomes H, and the output of the AND gate 35 changes to L, so that the passenger seat window motor 11 stops. Thereby, the motor 11 can be reliably stopped when the window is completely closed.

  On the other hand, when the other window opening / closing restriction switch 3 is operated (ON state), as shown in FIG. 25, the output of the other window opening / closing restriction switch 3 becomes H, and the window is opened by a predetermined amount Y or more. Then, since the output of the window position detection sensor 5a also becomes H, the output of the AND gate 31 becomes H. However, since one input of the AND gate 34 remains L, the outputs of the AND gates 34 and 36 are the case of FIG. As well as L. Since the outputs of the AND gates 32, 33, and 35 are not affected by the state of the other window opening / closing restriction switch 3, they become L, H, and H, respectively, as in the case of FIG. Therefore, the other seat window motor 11 is driven in the direction of closing the window by the H signal from the AND gate 35. At this time, the window closes regardless of the output of the window position detection sensor 5a. When the window is completely closed, the output of the window position detection sensor 5c becomes H and the output of the AND gate 35 becomes L as described above. Then, the other seat window motor 11 stops. In this way, when the “close” operation of the driver's seat other window operation switch 2 is prioritized over the “open” operation of the other seat operation switch 4 and the window is closed, the other window opening / closing restriction switch 3 is turned on. But the window closes to the end.

  FIG. 26 shows another embodiment of the present invention, in which the window for other seats is opened / closed by the driver's seat other window operation switch 2 in a state where the other window opening / closing restriction switch 3 is operated (ON state). In this case, a control circuit that performs control so as to prohibit control based on the operation of the other window opening / closing restriction switch 3 is shown.

  Reference numeral 2 is a driver's seat other window operation switch, 3 is an other window opening / closing restriction switch, 4 is an other seat operation switch, and 11 is an other seat window motor, which are the same as those shown in FIG. . The window position detection sensor includes a window position detection sensor 5a that operates when the window is opened by a predetermined amount Y, a window position detection sensor 5b that operates when the window is fully opened, and a window that is completely closed. It consists of the window position detection sensor 5c which operate | moves. 41 to 46 are AND gates, and 47 and 48 are OR gates. One input of the AND gates 41, 42, 44 to 46 is an inverting input.

  Next, the opening / closing control of the window by the control circuit of FIG. 26 will be described. FIG. 27 shows a case where the driver's seat other window operation switch 2 is operated to the “open” side in a state where the other window opening / closing restriction switch 3 is not operating (off state). In this case, the output on the “close” side of the driver's seat other window operation switch 2 is L, the output of the other window opening / closing restriction switch 3 is also L, and the output on the “open” side of the other seat operation switch 4 is The output on the “closed” side is also L. Accordingly, the outputs of the AND gates 41 and 42 are both L, and the output of the AND gate 43 is also L. For this reason, the output of the AND gate 44 is also L. Since the output of the OR gate 47 is L and the output of the window position detection sensor 5c is L, the output of the AND gate 45 is L. On the other hand, since the output on the “open” side of the driver's seat other window operation switch 2 is H, the output of the OR gate 48 is H. Further, the output of the window position detection sensor 5b is L until the window is completely opened. For this reason, the output of the AND gate 46 becomes H. Therefore, the other seat window motor 11 is driven in the direction to open the window by the H signal from the AND gate 46. When the window is opened by a predetermined amount Y, the output of the window position detection sensor 5a becomes H. However, since the output of the other window open / close limiting switch 3 remains L, the output of the AND gate 43 maintains L, and the window Opens to the end. When the window is completely opened, the output of the window position detection sensor 5b becomes H and the output of the AND gate 46 changes to L, so that the passenger seat window motor 11 stops.

  FIG. 28 shows a case where the driver's seat other window operation switch 2 is operated to the “open” side in a state where the other window opening / closing restriction switch 3 is operated (ON state). In this case, the states of the AND gates 41, 42, 45 and the OR gate 47 are the same as in FIG. Further, since the output of the other window opening / closing restriction switch 3 becomes H, one input of the AND gate 43 becomes H, but the output of the AND gate 43 remains L until the window position detection sensor 5a operates. Therefore, the output of the AND gate 44 does not change with L. Therefore, the state of the OR gate 48 is not different from that in FIG. 27, and the output of the OR gate 48 is H. Further, the output of the window position detection sensor 5b is L until the window is completely opened. For this reason, the output of the AND gate 46 becomes H. Therefore, the other seat window motor 11 is driven in the direction to open the window by the H signal from the AND gate 46. When the window is opened by a predetermined amount Y, the output of the window position detection sensor 5a becomes H and the output of the AND gate 43 becomes H, but the outputs of the OR gates 47 and 48 do not change. For this reason, the window opens to the end. When the window is completely opened, the output of the window position detection sensor 5b becomes H and the output of the AND gate 46 changes to L, so that the passenger seat window motor 11 stops.

  In this way, even when the other window opening / closing restriction switch 3 is turned on, the control operation by the other window opening / closing restriction switch 3 can be prevented by operating the driver's seat other window operation switch 2. it can. In the circuit of FIG. 26, when the window is closed, the restriction by the other window opening / closing restriction switch 3 does not work. However, when the logic circuit is configured so that this restriction works, the driver's seat etc. By restricting the window operation switch 2 to the “closed” side, restriction of the window closing operation may be prohibited.

  FIG. 29 is another embodiment of the present invention, and the range in which the window can be opened when the other-seat operation switch 4 is “opened” while the other window opening / closing restriction switch 3 is operated. And a control circuit that performs control so as to limit the range in which the window can be closed even when the other-seat operation switch 4 is “closed”.

  Reference numeral 2 is a driver's seat other window operation switch, 3 is an other window opening / closing restriction switch, 4 is an other seat operation switch, and 11 is an other seat window motor, which are the same as those shown in FIG. . The window position detection sensor includes a window position detection sensor 5a that operates when the window is opened by a predetermined amount Y, a window position detection sensor 5b that operates when the window is fully opened, and a window that is completely closed. The window position detection sensor 5c operates and the window position detection sensor 5d operates when the window is opened by Y + α. 51 to 59 are AND gates, and 60 and 61 are OR gates. One input of the AND gates 52 to 55 and 57 to 59 is an inverting input.

  Next, window opening / closing control by the control circuit of FIG. 29 will be described. FIG. 30 shows a case where the other-seat operation switch 4 is operated to the “open” side (when the window is opened) in a state where the other window opening / closing restriction switch 3 is operated (ON state). In this case, the output on the “open” side and the output on the “close” side of the driver's seat other window operation switch 2 are both L, the output of the other window opening / closing restriction switch 3 is H, and “ The output on the “open” side is H, and the output on the “closed” side is L. The outputs of the window position detection sensors 5a to 5d are all L. As a result, the states of H and L in the input / output of each of the gates 51 to 61 are as shown in FIG. 30, and the other seat window motor 11 is driven in the direction to open the window by the H signal from the AND gate 59. . When the window is opened by a predetermined amount Y, as shown in FIG. 31, the window position detection sensor 5a operates and the output of the AND gate 56 becomes H and the output of the AND gate 57 becomes L. The window motor 11 stops. Therefore, after that, even if the other-seat operation switch 4 is continuously pressed to the “open” side, the window is not opened.

  FIG. 32 shows a case where the other-seat operation switch 4 is operated to the “closed” side (when the window is closed) in a state where the other window opening / closing restriction switch 3 is operated (ON state). In this case, the output on the “open” side and the output on the “close” side of the driver's seat other window operation switch 2 are both L, the output of the other window opening / closing restriction switch 3 is H, and “ The output on the “open” side is L, and the output on the “closed” side is H. At this time, as shown in FIG. 35, if the opening amount X of the window 100 is Y + α or more, the outputs of the window position detection sensors 5a and 5d are H, and the outputs of the window position detection sensors 5b and 5c are L. It is. As a result, the states of H and L at the inputs and outputs of the gates 51 to 61 are as shown in FIG. 32, and the output of the AND gate 58 becomes L. Not driven. Therefore, the window cannot be closed from the state shown in FIG.

  On the other hand, as shown in FIG. 36, when the opening amount X of the window 100 is Y or more and smaller than Y + α, the window position detection sensor 5d is turned off and the output of the AND gate 51 is L, as shown in FIG. The output of the AND gate 53 becomes H. As a result, the output of the OR gate 61 is H, the output of the AND gate 55 is H, and the output of the AND gate 58 is H. Accordingly, the other seat window motor 11 closes the window by the H signal from the AND gate 58. Driven by. Therefore, the window can be closed from the state shown in FIG.

  As shown in FIG. 37, when the opening amount X of the window 100 is smaller than Y, the window position detection sensor 5a is also turned off and the output of the AND gate 56 becomes L as shown in FIG. However, the output of the AND gate 57 is L as in FIG. 33, and the input / output states of the other gates are the same as in FIG. Therefore, the other seat window motor 11 is driven in the direction of closing the window by the H signal from the AND gate 58. Therefore, the window can be closed also in the case of FIG.

  As can be seen from the above, according to the control circuit of FIG. 29, when the opening amount X of the window 100 is X ≧ Y + α as shown in FIG. 35, it is prohibited to open or close the window 100, as shown in FIG. When the opening amount X of the window 100 is Y ≦ X <Y + α, the window 100 cannot be opened and can only be closed. When the opening amount X of the window 100 is X <Y as shown in FIG. The window 100 can be opened and closed.

  In the control circuit of FIG. 29, when the driver's seat other window operation switch 2 is used to close the window of the other seat, when the switch 2 is operated to the “closed” side, the output of the OR gate 61 is always H, AND gate. Since the outputs of 55 and 58 are H, the window can be closed even in the case of FIG. 35, but the logic circuit may be configured to prohibit this in the same manner as described above.
