Abstract

PROBLEM TO BE SOLVED: To ensure safety of passengers on other seats when opening/closing windows of the other seats by a remote operation from a driver seat.SOLUTION: An opening/closing control device for a vehicle comprises: a switch S2 provided on a driver seat for opening/closing windows of seats other than the driver seat; switches S3 provided on the other seats for opening/closing the windows thereof; and a seating sensor K to detect whether or not a passenger is present on each seat. When closing the window of another seat by a remote operation of the switch S2 on the driver seat in a state that the seating sensor K detects a presence of the passenger, a relay RY is activated and an electric current flows through a motor M2 via a limit resistance R. As a result, the current flowing through the motor M2 is reduced and the motor M2 rotates at a velocity lower than usual to slowly close the window of the seat.

Description

  The present invention relates to a vehicle opening / closing body control device that controls opening / closing of a window or a door of a vehicle, and more particularly to a technique for ensuring safety during opening / closing.

  In a power window device that opens and closes a window of a vehicle by an electric motor, the motor is rotated in the normal rotation direction or the reverse rotation direction in accordance with the operation state of the operation switch to open and close the window. For example, when the operation switch is operated to the UP side (window closing side), the motor is driven in the forward rotation direction and the window is closed, and when the operation switch is operated to the DOWN side (window opening side), the motor is driven in the reverse rotation direction. Window opens. Control of forward and reverse rotation of the motor is performed by switching the direction of the current flowing through the motor in the motor drive circuit based on the signal from the operation switch.

  In general, in an automobile, an operation switch for opening and closing a window is provided in each of a driver seat and other seats (passenger seat and rear seat). The operation switch provided in the driver's seat includes a driver's seat switch for operating the opening / closing of the driver's seat window, and a switch for other seats for operating the opening / closing of the window of the other seat such as the passenger seat. The driver seat side control unit and the other seat side control unit are electrically connected. For this reason, by operating the switch for other seats in the driver's seat, the windows of the passenger seat and the rear seat can be opened and closed by remote control. Such power window devices that open and close the windows of other seats by remote control from the driver's seat are described, for example, in Patent Documents 1 and 2 below.

JP-A-4-358922 JP-A-11-268531

  When closing a window with a power window device, it is necessary to ensure safety by preventing foreign objects from being caught. In particular, when operating the switch for other seats in the driver's seat and closing the window of the other seat, if the driver operates the switch without carefully checking the state of the passenger seated in the other seat, Safety is threatened by rapidly closing windows.

  An object of the present invention is to provide a vehicle opening / closing body control device capable of ensuring the safety of an occupant in the vicinity of an opening / closing body when the opening / closing body is opened / closed by remote control at a place away from the opening / closing body such as a window. It is to provide.

  The vehicle opening / closing body control apparatus according to the present invention includes a first operation unit operated near the opening / closing body to open / close the opening / closing body provided in the vehicle, and the opening / closing body for remotely opening / closing the opening / closing body. Opening / closing body is opened by opening operation of the second operation section operated at a location away from the first operation section or the second operation section, and opening / closing body is closed by closing operation of the first operation section or the second operation section An opening / closing body control device for a vehicle having body driving means, comprising: a detecting means for detecting the presence or absence of an occupant near the opening / closing body, wherein the opening / closing body driving means detects the occupant and the second operation When the closing operation is performed at the portion, the opening / closing body is closed at a lower speed than when the closing operation is performed at the first operation portion.

  In this way, when the opening / closing body is closed by remote control of the second operation unit in the state where the passenger is near the opening / closing body, the opening / closing body is closed at a lower speed than in the normal case. Therefore, for example, even if there is an occupant in the rear seat of the vehicle and the driver performs an operation of closing the rear seat window in the second operation portion without carefully checking the rear, the rear seat window closes slowly. The safety of passengers is not threatened.

  In the present invention, the first operation unit is, for example, a switch provided in a seat other than the driver's seat to open and close the window of the other seat, and the second operation unit is provided in the driver's seat, for example. It is a switch for opening and closing the seat window.

  In the present invention, the opening / closing body driving means includes, for example, a first contact that is switched by an operation of the first operation unit, a second contact that is switched by an operation of the second operation unit, and a current that flows in a motor for opening and closing the opening / closing body. And a current limiting resistor for limiting. In this case, the opening / closing body driving means is closed by the first operating section via the second contact and the current limiting resistor when the detecting means detects an occupant and the closing operation is performed by the second operating section. A smaller current is supplied to the motor than when the operation is performed.

  In the present invention, the opening / closing body driving means may include a motor driving circuit for driving a motor for opening / closing the opening / closing body and a control unit for controlling the motor driving circuit. In this case, the control unit detects that the occupant is detected by the detection unit, and the current flowing in the motor when the closing operation is performed by the second operation unit is greater than the case where the closing operation is performed by the first operation unit. The motor drive circuit is controlled so that the current becomes smaller.

  In the present invention, the detection means is, for example, a seating sensor that detects the seating of an occupant.

  In this invention, it may replace with a detection means and may use the lock switch for locking the door of a vehicle. In this case, the opening / closing body driving means is more effective than the case where the opening / closing body is closed by the first operation portion when the lock switch is in the ON state and the closing operation is performed by the second operation portion. Also close at a low speed.

  In the present invention, the second operation unit may be a portable remote controller that can be remotely operated from the outside of the vehicle.

  According to the present invention, when the opening / closing body is closed by a remote operation of the second operation unit in a state where the passenger is near the opening / closing body, the opening / closing body is closed at a low speed, so that the safety of the passenger can be ensured.

  Hereinafter, an embodiment in which the present invention is applied to a power window device will be described with reference to the drawings. In each drawing, the same reference numerals are given to the same parts or corresponding parts.

<First Embodiment>
FIG. 1 shows a power window device 100 according to the first embodiment. The power window device 100 includes window opening / closing switches S1 to S3, window opening / closing motors M1 and M2, a relay RY, a seating sensor K, a current limiting resistor R, and a power source B.

  The switch S1 is a switch provided on the door of the driver's seat and operated to open and close the driver's seat window. The switch S2 is a switch that is provided on the door of the driver's seat and is operated to open and close windows of seats other than the driver's seat (passenger seat and rear seat). The switch S3 is a switch provided on the door of the other seat and operated to open and close the window of the other seat. Here, for simplicity of explanation, only one switch S2 and S3 for other seats is shown.

  The motor M1 is a motor for opening and closing the driver's seat window, and is connected to the switch S1. The switch S1 has two contacts S1u and S1d. The contact S1u is switched from the b side to the a side when the switch S1 is closed (a window closing operation). The contact S1d is switched from the b side to the a side when the switch S1 is opened (opening the window). Each a side of the contacts S1u and S1d is connected to the power source B. Each b side of the contacts S1u and S1d is connected to the ground.

  The motor M2 is a motor for opening and closing the windows of other seats, and is connected to the switch S3. The switch S3 has two contacts S3u and S3d. The contact S3u is switched from the b side to the a side when the switch S3 is closed. The contact S3d is switched from the b side to the a side when the switch S3 is opened. Each a side of the contacts S3u and S3d is connected to the power source B. The b side of the contact S3u is connected to the contact S2u of the switch S2. The b side of the contact S3d is connected to the contact S2d of the switch S2.

  The contact S2u of the switch S2 is switched from the b side to the a side when the switch S2 is closed. The contact S2d is switched from the b side to the a side when the switch S2 is opened. The a side of the contact S2u is connected to the contact Y of the relay RY. The a side of the contact S2d is connected to the power source B. Each b side of the contacts S2u and S2d is connected to the ground.

  The relay RY has a coil X and a contact Y. One end of the coil X is connected to the power source B via the seating sensor K. The other end of the coil X is connected to the ground. When the coil X is energized, the contact Y switches from the b side to the a side. The a side of the contact Y is connected to the power source B via the current limiting resistor R. The b side of the contact Y is directly connected to the power source B.

  The above-described contact S1u, contact S1d, contact S2u, contact S2d, relay RY and current limiting resistor R are provided in one control unit.

  The seating sensor K is composed of, for example, a pressure sensor and is provided in the seat of the other seat. When the occupant sits on the seat, the pressure sensor detects the pressure based on the weight of the occupant and outputs a detection signal. In FIG. 1, for convenience, the seating sensor K is represented by a contact. It is assumed that the detection signal is not output from the pressure sensor when the contact is open (off state), and the detection signal is output from the pressure sensor when the contact is closed (on state).

  FIG. 2 is a top view illustrating an example of the switches S1 to S3. A switch box 10 as shown in FIG. 2A is provided on the door of the driver's seat. The switch box 10 is provided with a switch S1 for the driver's seat window and a switch S2 for the other seat window, as well as lock switches S4 (for the left door) and S5 (for the right door) for locking the rear seat door. For doors). When the lock switches S4 and S5 are operated, the door knob operation from the inside of the rear seat becomes invalid. That is, the lock switches S4 and S5 prevent the child from opening the door from the inside of the vehicle. The lock switches S4 and S5 are called child lock switches. Moreover, the switch box 20 as shown in FIG.2 (b) is provided in the door of the passenger seat and the rear seat, respectively. The switch box 20 is provided with only the switch S3 for the other seat window. The detailed structure of the switches S1 to S5 is described in, for example, Japanese Patent No. 4312739.

  In the above configuration, the switch S3 is a switch operated near the window of the other seat and corresponds to the “first operation unit” in the present invention. The switch S2 is a switch that is remotely operated in the driver's seat away from the windows of other seats, and corresponds to the “second operation unit” in the present invention. The contact S2u, the contact S2d, the contact S3u, the contact S3d, the relay RY, and the current limiting resistor R correspond to the “opening / closing body driving means” in the present invention. The contact S3u and the contact S3d correspond to the “first contact” in the present invention, and the contact S2u and the contact S2d correspond to the “second contact” in the present invention. The seating sensor K corresponds to “detecting means” in the present invention. The switches S1 to S3, the relay RY, the seating sensor K, and the current limiting resistor R constitute a vehicle opening / closing body control device.

  Next, the operation of the power window device 100 described above will be described. When none of the switches S1 to S3 is operated and the seating sensor K is not outputting a detection signal (in an off state), the circuit is in the state shown in FIG. In this state, since the energization path from the power source B to the motors M1 and M2 is not formed, the motors M1 and M2 do not rotate. Therefore, the window is not opened or closed.

  The operation when the window is opened and closed will be described with reference to FIGS. Hereinafter, an operation for closing a window (closing operation) is referred to as an “UP operation”, and an operation for opening a window (opening operation) is referred to as a “DOWN operation”.

(1) In case of UP operation to close the driver's seat window in the driver's seat (Fig. 3)
When the switch S1 is UP-operated, the contact S1u is switched from the b side to the a side. For this reason, as indicated by a thick line arrow in FIG. 3, a current flows through a path of power source B → contact S1u → motor M1 → contact S1d → ground. The direction of the current flowing through the motor M1 at this time is defined as a “positive direction”. When a forward current flows through the motor M1, the motor M1 rotates forward and the driver's seat window closes.

(2) When DOWN operation is performed to open the driver's seat window in the driver's seat (Fig. 4)
When the switch S1 is DOWN operated, the contact S1d is switched from the b side to the a side. For this reason, as indicated by a thick arrow in FIG. 4, a current flows through a path of power source B → contact S1d → motor M1 → contact S1u → ground. The direction of the current flowing through the motor M1 at this time is defined as “reverse direction”. When a current in the reverse direction flows through the motor M1, the motor M1 reverses and the driver's seat window opens.

(3) When the UP operation is performed to close the other seat window at another seat (Fig. 5)
When the switch S3 is UP-operated, the contact S3u is switched from the b side to the a side. For this reason, as indicated by the thick line arrow in FIG. 5, a current flows through a path of power source B → contact S3u → motor M2 → contact S3d → contact S2d → ground. The direction of the current flowing through the motor M2 at this time is defined as a “positive direction”. When a forward current flows through the motor M2, the motor M2 rotates forward and the other seat window closes.

(4) When a DOWN operation is performed to open the other seat window at another seat (FIG. 6)
When the switch S3 is DOWN-operated, the contact S3d is switched from the b side to the a side. For this reason, as indicated by the thick line arrow in FIG. 6, a current flows through a path of power source B → contact S3d → motor M2 → contact S3u → contact S2u → ground. The direction of the current flowing through the motor M2 at this time is referred to as “reverse direction”. When a current in the reverse direction flows through the motor M2, the motor M2 reverses and the other seat window opens.

(5) When UP operation is performed to close the other seat window in the driver's seat (Fig. 7)
When the switch S2 is UP-operated, the contact S2u is switched from the b side to the a side. Therefore, as indicated by the thick arrow in FIG. 7, a current flows through the path of the power source B → the contact Y of the relay RY → the contact S2u → the contact S3u → the motor M2 → the contact S3d → the contact S2d → the ground. The direction of the current flowing through the motor M2 at this time is the positive direction. Therefore, the motor M2 rotates forward and the other seat window closes. Thus, the windows of other seats can be closed by remote control from the driver's seat.

(6) When DOWN operation is performed to open the other seat window in the driver's seat (Fig. 8)
When the switch S2 is DOWN operated, the contact S2d is switched from the b side to the a side. For this reason, as shown by a thick arrow in FIG. 8, a current flows through a path of power source B → contact S2d → contact S3d → motor M2 → contact S3u → contact S2u → ground. The direction of the current flowing through the motor M2 at this time is the reverse direction. Therefore, the motor M2 reverses and the other seat window opens. Thus, the windows of other seats can be opened by remote control from the driver's seat.

(7) When the seating sensor detects seating (FIG. 9)
When an occupant sits on another seat and the seating sensor K detects the seating, the seating sensor K is turned on. For this reason, as indicated by the thick line arrow in FIG. Then, when the coil X of the relay RY is energized, the contact Y of the relay RY is switched from the b side to the a side. However, when the switches S1 to S3 are not operated, the contact points S1u, S1d, S2u, S2d, S3u, and S3d are not switched, so that the energization path from the power source B to the motors M1 and M2 is not formed. Therefore, the motors M1 and M2 do not rotate and the windows are not opened and closed.

(8) When the seating sensor detects the seating and performs an UP operation to close the other seat window at the driver's seat (FIG. 10)
The operation in this case is a feature of the present invention. When the seating sensor K detects the seating, as described above, a current flows through the path of the power source B → the seating sensor K → the relay X of the relay RY → the ground, and the contact Y of the relay RY is switched from the b side to the a side. On the other hand, the contact S2u is switched from the b side to the a side by the UP operation of the switch S2. For this reason, a current flows through a path of power source B → current limiting resistor R → contact RY of relay RY → contact S2u → contact S3u → motor M2 → contact S3d → contact S2d → ground. Since the direction of the current flowing through the motor M2 at this time is the positive direction, the motor M2 rotates forward and the window of the other seat is closed. However, since the current flowing through the motor M2 flows through the current limiting resistor R, the current is smaller than the current flowing through the motor M2 in FIG. 5 (when the UP operation is performed by the switch S3 in the other seat). As a result, the motor M2 rotates at a lower speed than in the case of FIG. 5, so that the window of the other seat closes slowly.

(9) When the DOWN operation is performed to open the other seat window in the driver's seat while the seating sensor detects the seating (FIG. 11).
When the seating sensor K detects the seating, as described above, a current flows through the path of the power source B → the seating sensor K → the relay X of the relay RY → the ground, and the contact Y of the relay RY is switched from the b side to the a side. On the other hand, the contact S2d is switched from the b side to the a side by the DOWN operation of the switch S2. For this reason, a current flows through a path of power source B → contact S2d → contact S3d → motor M2 → contact S3u → contact S2u → ground. Since the direction of the current flowing through the motor M2 at this time is the reverse direction, the motor M2 reverses and the other seat window opens. In this case, since the current flowing through the motor M2 does not flow through the current limiting resistor R, the other seat window is closed at a normal speed.

  According to the first embodiment described above, when the passenger's seat is closed by remote control of the driver's switch S2 in a state where an occupant is seated in the other seat, the motor M2 rotates at a lower speed than usual. To do. For this reason, for example, even when there is an occupant in the rear seat of the vehicle and the driver performs an operation of closing the rear seat window with the switch S2 without carefully checking the rear, the rear seat window is slowly closed. Thereby, the foreign object can be prevented from being caught in the rear seat. In particular, it is possible to prevent a person who is unfamiliar with how to handle a car such as a child from accidentally pinching a foreign object into the window, thereby ensuring safety.

Second Embodiment
FIG. 12 shows a power window device 200 according to the second embodiment. Here, instead of the seating sensor K in FIG. 1, a lock switch S4 (see FIG. 2) is used. In order to simplify the description, only one lock switch is shown.

  The configuration of the power window device 200 is the same as that of the power window device 100 of the first embodiment except that the seating sensor K in FIG. 1 is replaced with a lock switch S4. Therefore, the operation of the circuit of FIG. 12 can also be easily understood from the operations described with reference to FIGS.

  For example, when the door is locked, that is, when the lock switch S4 is in the ON state, the operation when the UP operation for closing the other seat window is performed in the driver's seat is as follows.

  When the lock switch S4 is turned on, a current flows through a path from the power source B → the lock switch S4 → the coil X of the relay RY → the ground, and the contact Y of the relay RY is switched from the b side to the a side. On the other hand, the contact S2u is switched from the b side to the a side by the UP operation of the switch S2. For this reason, a current flows through a path of power source B → current limiting resistor R → contact RY of relay RY → contact S2u → contact S3u → motor M2 → contact S3d → contact S2d → ground. Since the direction of the current flowing through the motor M2 at this time is the positive direction, the motor M2 rotates forward and the window of the other seat is closed. However, since the current flowing through the motor M2 flows through the current limiting resistor R, the current is smaller than the current flowing through the motor M2 in FIG. 5 (when the UP operation is performed by the switch S3 in the other seat). As a result, the motor M2 rotates at a lower speed than in the case of FIG. 5, so that the window of the other seat closes slowly.

  In the case of the second embodiment, as described above, the lock switch S4 is a child lock switch for locking the door so that the child does not open the door without permission, and is operated by the driver. Therefore, when the lock switch S4 is on, it is assumed that there are children in other seats. In this case, the motor M2 is rotated at a low speed and the window is closed slowly, which is the case of the first embodiment. Similarly to this, it is possible to prevent foreign objects from being caught and to ensure the safety of passengers (particularly children).

<Third Embodiment>
FIG. 13 shows a power window device 300 according to the third embodiment. In the first and second embodiments, the motor current is limited by the current limiting resistor R in order to rotate the motor M2 at a low speed, but in the third embodiment, by controlling the motor drive circuit by the control unit, Limit motor current.

  In FIG. 13, a power window device 300 includes a CPU 1 constituting a control unit, a motor drive circuit 2 that drives a motor M1 in a driver's seat, a rotation speed detection sensor 3 that detects the rotation speed of the motor M1, and a motor M2 in another seat. A motor drive circuit 4 for driving, a rotation speed detection sensor 5 for detecting the rotation speed of the motor M2, switches S1 to S3, and a seating sensor K are provided. The switches S1 to S3 and the seating sensor K are the same as those shown in FIG.

  The CPU 1 receives signals from the switches S1 to S3 and the seating sensor K and signals from the rotation speed detection sensors 3 and 5. The rotation speed detection sensors 3 and 5 are composed of, for example, a rotary encoder. The motor drive circuits 2 and 4 are configured by a known circuit including, for example, a PWM (Pulse Width Modulation) circuit and a bridge circuit including four transistors. Such a motor drive circuit is described in, for example, Japanese Patent Application Laid-Open Nos. 2007-131017 and 2001-268777.

  The CPU 1 compares the rotational speeds of the motors M1 and M2 detected by the rotational speed detection sensors 3 and 5 with a target value, and calculates a command value for the motors M1 and M2 based on the deviation. Here, the duty ratio of the PWM signal for driving the motors M1 and M2 is the command value. The CPU 1 outputs this command value to the motor drive circuits 2 and 4. The motor drive circuits 2 and 4 generate a PWM signal having a duty ratio corresponding to the command value, and drive the motors M1 and M2 based on the PWM signal. As a result, feedback control is performed on the motors M1 and M2.

  In the above configuration, the CPU 1 and the motor driving circuits 2 and 4 correspond to “opening / closing body driving means” in the present invention. The switches S1 to S3, the seating sensor K, the CPU 1, and the motor drive circuits 2 and 4 constitute a vehicle opening / closing body control device.

Next, the operation of the power window device 300 of the third embodiment will be described.
(1) When UP operation is performed to close the driver's seat window at the driver's seat When the switch S1 is UP-operated, a command for causing the motor M1 to normally rotate at a normal rotational speed is given from the CPU 1 to the motor drive circuit 2. The motor drive circuit 2 generates a PWM signal corresponding to this command, and drives the motor M1 by switching the transistor of the bridge circuit with the PWM signal. As a result, the motor M1 rotates forward and the driver's seat window closes at a normal speed.

(2) When DOWN operation is performed to open the driver's seat window in the driver's seat When the switch S1 is DOWN operated, a command for reversing the motor M1 at a normal rotational speed is given from the CPU 1 to the motor drive circuit 2. The motor drive circuit 2 generates a PWM signal corresponding to this command, and drives the motor M1 by switching the transistor of the bridge circuit with the PWM signal. This reverses the motor M1 and opens the driver's seat window at a normal speed.

(3) When UP operation is performed to close the other-seat window at another seat When the switch S3 is UP-operated, a command for causing the motor M2 to normally rotate at a normal rotational speed is given from the CPU 1 to the motor drive circuit 4. The motor drive circuit 4 generates a PWM signal corresponding to this command, and drives the motor M2 by switching the transistors of the bridge circuit with the PWM signal. As a result, the motor M2 rotates forward and the window of the other seat closes at a normal speed.

(4) When DOWN operation is performed to open the other-seat window at the other seat When the switch S3 is operated to DOWN, the CPU 1 gives a command for reversing the motor M2 at a normal rotational speed to the motor drive circuit 4. The motor drive circuit 4 generates a PWM signal corresponding to this command, and drives the motor M2 by switching the transistors of the bridge circuit with the PWM signal. As a result, the motor M2 reverses and the other seat window opens at a normal speed.

(5) When UP operation is performed to close the other-seat window at the driver's seat When the switch S2 is UP-operated, a command for causing the motor M2 to normally rotate at a normal rotational speed is given from the CPU 1 to the motor drive circuit 4. The motor drive circuit 4 generates a PWM signal corresponding to this command, and drives the motor M2 by switching the transistors of the bridge circuit with the PWM signal. As a result, the motor M2 rotates forward and the window of the other seat closes at a normal speed.

(6) When DOWN operation is performed to open the other-seat window at the driver's seat When the switch S2 is DOWN-operated, a command for reversing the motor M2 at a normal rotational speed is given from the CPU 1 to the motor drive circuit 4. The motor drive circuit 4 generates a PWM signal corresponding to this command, and drives the motor M2 by switching the transistors of the bridge circuit with the PWM signal. As a result, the motor M2 reverses and the other seat window opens at a normal speed.

(7) When the seating sensor detects the seating When the occupant sits in another seat and the seating sensor K detects the seating, a seating detection signal is input from the seating sensor K to the CPU 1. However, when the switches S1 to S3 are not operated, no command is output from the CPU 1 to the motor drive circuits 2 and 4. For this reason, the motors M1 and M2 do not rotate and the windows are not opened and closed.

(8) When the seating sensor detects seating and performs an UP operation to close the other seat window at the driver's seat. The operation in this case is a feature of the present invention. When the seating sensor K detects the seating, a seating detection signal is input to the CPU 1 as described above. On the other hand, the window closing signal is input to the CPU 1 from the switch S2 by the UP operation of the switch S2. For this reason, the CPU 1 gives a command for causing the motor M2 to rotate forward at a speed slower than the normal rotation speed. In this command, the duty ratio of the PWM signal is set smaller than in the normal case. The motor drive circuit 4 generates a PWM signal having a duty ratio corresponding to this command, and drives the motor M2 by switching the transistors of the bridge circuit with the PWM signal. Thereby, the motor M2 rotates forward at a low speed, and the window of the other seat closes at a speed slower than the normal speed.

(9) In the state where the seating sensor detects the seating, when the DOWN operation is performed to open the other seat window at the driver's seat When the seating sensor K detects the seating, the seating detection signal is input to the CPU 1 as described above. On the other hand, a window opening signal is input to the CPU 1 from the switch S2 by the DOWN operation of the switch S2. Therefore, a command for reversing the motor M2 at a normal rotation speed is given from the CPU 1 to the motor drive circuit 4. The motor drive circuit 4 generates a PWM signal corresponding to this command, and drives the motor M2 by switching the transistors of the bridge circuit with the PWM signal. As a result, the motor M2 reverses and the other seat window opens at a normal speed.

  According to the third embodiment described above, when the passenger's seat is closed by the remote operation of the driver's seat switch S2 while the passenger is seated in the other seat, the motor M2 rotates at a lower speed than usual. So close the window slowly. For this reason, as in the case of the first embodiment, it is possible to prevent foreign objects from being caught and to ensure the safety of the occupant.

<Fourth embodiment>
FIG. 14 shows a power window device 400 according to the fourth embodiment. Here, in addition to the configuration of FIG. 13, a portable remote controller 6 is provided. The remote controller 6 can be remotely operated from the outside of the vehicle, and corresponds to a “second operation unit” in the present invention. Communication between the remote controller 6 and the CPU 1 is performed wirelessly.

  The remote controller 6 is provided with a key (not shown) having the same function as the switches S1 to S3. Therefore, by operating the remote controller 6, the same operation as in the third embodiment is performed. For example, when the seating sensor K detects the seating and the remote controller 6 performs an UP operation to close the other seat window, the operation is as follows.

  When the seating sensor K detects seating, a seating detection signal is input to the CPU 1. On the other hand, a window closing signal is input to the CPU 1 from the remote controller 6 by an UP operation on the remote controller 6. For this reason, the CPU 1 gives a command for causing the motor M2 to rotate forward at a speed slower than the normal rotation speed. In this command, the duty ratio of the PWM signal is set smaller than in the normal case. The motor drive circuit 4 generates a PWM signal having a duty ratio corresponding to this command, and drives the motor M2 by switching the transistors of the bridge circuit with the PWM signal. Thereby, the motor M2 rotates forward at a low speed, and the window of the other seat closes at a speed slower than the normal speed.

  According to the fourth embodiment, when the occupant is seated in another seat and the remote controller 6 is remotely operated to close the window of the other seat, the motor M2 rotates at a lower speed than usual. Close slowly. For this reason, as in the case of the first embodiment, it is possible to prevent foreign objects from being caught and to ensure the safety of the occupant.

  In the present invention, various embodiments other than those described above can be adopted. For example, in the third embodiment (FIG. 13), the lock switch S4 of FIG. 12 may be used instead of the seating sensor K. The same applies to the fourth embodiment (FIG. 14).

  In the above embodiment, the seating sensor K formed of a pressure sensor is taken as an example of the detection means for detecting the presence or absence of an occupant. However, the present invention is not limited to this, and an optical sensor or the like may be used as the detection means.

  Further, when any of the seating sensors provided in each of the rear seats detects an occupant, the motor M2 may be driven at a low speed even when any of the windows on the rear seat is closed. Good.

  Moreover, although the case where the seating sensor K was contained in the vehicle opening / closing body control apparatus was mentioned as an example in the said embodiment, the seating sensor K may be externally attached to the vehicle opening / closing body control apparatus. In that case, the relay RY (FIG. 1) and the CPU 1 (FIGS. 13 and 14) that perform a predetermined operation based on a signal from the seating sensor K correspond to the “detecting means” in the present invention.

  Furthermore, in each embodiment described above, the vehicle window is taken as an example of the opening and closing body, but the present invention can also be applied to the case of opening and closing the vehicle door.
