(Operation) According to the first and seventh aspects of the present invention, in the operating area of the slide door, there is provided a low speed operating area for operating the door at a low speed and a high speed operating area for operating the door at a high speed. The rotation speed of the drive motor is controlled according to each area to open and close the door (opening / closing control means). Then, during the closing operation of the slide door, it is detected whether or not there is a possibility that a foreign object has been caught between the door and the vehicle body (entrapment detection means). When the entrapment is detected, the slide door is opened. The drive motor is controlled to reverse the door in the opening direction at high speed regardless of the area where the door is located (reversal control means). That is, even when the trapping by the sliding door is detected while the sliding door is operating in the low speed operation area, the door is reversed at high speed. Therefore, it becomes possible to always release the trapped foreign matter in a shorter time.

The speed is controlled and the door is opened / closed (opening / closing control means). Then, during the closing operation of the slide door, it is detected whether or not there is a possibility that a foreign object has been caught between the door and the vehicle body (entrapment detection means). When the entrapment is detected, the slide door is opened. The drive motor is controlled to reverse the door in the opening direction at high speed regardless of the area where the door is located (reversal control means). In other words, even when the sliding door is operated in a low speed operation area, for example, in the closing side predetermined area, even if the trapping by the door is detected, the door is reversed at high speed. Therefore, it becomes possible to always release the trapped foreign matter in a shorter time.

Therefore, it is detected that the foreign matter is caught when the foreign matter hits the door (pressure sensor) before the foreign matter is sufficiently sandwiched between the slide door and the vehicle body.
Therefore, the trapping can be detected earlier, and the trapped foreign matter can be released in a shorter time.

According to the invention described in claim 5, the drive motor has a common brush, a low speed brush and a high speed brush, and the opening / closing control means and the reversing control means are used when the slide door is operated at a low speed. Supplies the drive power to the drive motor via the common brush and the low speed brush, and supplies the drive power to the drive motor via the common brush and the high speed brush when operating the slide door at a high speed. Therefore, the rotational speed of the drive motor can be changed (the operating speed of the slide door can be changed) simply by switching the brush that supplies the drive power without requiring complicated speed control.
Can be done easily. Further, when the drive motor is driven at a low speed, the rotation speed of the motor becomes not only a low speed but also a high torque. Here, when the low speed operation region is set near the fully closed position, a reaction force is received from the weather strip, the door latch mechanism and the like in this region, so that the sliding door requires a relatively large closing force. Therefore, since the drive motor has high torque in this region, a large closing force can be applied to the slide door. Also, when the low-speed operation area is set near the fully open position, a relatively large force in the fully open direction is required for the door because a reaction force from the holding mechanism for holding the slide door at the fully open position is received in this area. Becomes Therefore, since the drive motor has high torque in this region, a large force in the fully opening direction can be applied to the slide door.

According to the sixth aspect of the present invention, the sliding door is reversed by a predetermined amount during the reverse operation due to the sandwiching. In other words, if the sliding door is reversed by a predetermined amount, the foreign matter that has been sandwiched can be sufficiently released, so that the time required for the reverse operation can be shortened.

And an endless belt 12 that transmits the driving force of the drive motor 11 to the center arm 9.

The drive motor 11 is constructed by integrally assembling a motor body 13 and a speed reducer 14 that reduces the rotation of the motor body 13 and transmits the rotation to a drive pulley 15 fixed to the output shaft of the drive motor 11. ing. Drive motor 1
1 is arranged in the vehicle main body 1 such that the axial direction of the drive pulley 15 faces the vertical direction of the vehicle main body 1. The endless belt 12 is wound around the drive pulley 15 and a plurality of driven pulleys 16 which are separated from the drive pulley 15 and are arranged at predetermined intervals. When the drive motor 11 is driven and the drive pulley 15 rotates, the endless belt 12

Further, as shown in FIGS. 4 and 5, at the front end portion of the slide door 3, a pressure sensor 17 constituting a pinch detecting means extending from the upper portion to the lower portion of the door is provided.
Is attached. Incidentally, although not shown, the pressure-sensitive sensor 17 has an outer skin made of an elastic material having an insulating property such as rubber or a soft synthetic resin material, and a plurality of electrode wires are housed therein at predetermined intervals. ing. Then, when a predetermined pressing force acts on the outer skin of the pressure sensor 17 from the outside and elastically deforms (collapses), the inner electrode wires come into contact with each other and become conductive, and by detecting the conductive state,
It is configured to detect that a pressing force is applied from the outside and output a pressure detection signal. Therefore, the sliding door 3
When a foreign object is caught between the door 3 and the vehicle body 1 while the vehicle is being closed by the drive motor 11, the pressure sensor 17 is elastically deformed (crushed) by the foreign object. Is detected.

Next, FIG. 1 shows a slide door opening / closing device 10.
The electrical configuration of is shown. The slide door opening / closing device 10 is controlled by a controller 21 that constitutes an opening / closing control unit, a pinch detection unit, and a reversal control unit. The controller 21 is provided, for example, near the drive motor 11 or integrally with the drive motor 11. The controller 21
Drive power is supplied from a battery 22 provided in the vehicle body 1.

An opening / closing operation signal for opening / closing the slide door 3 is input to the controller 21 from the opening / closing switch 23. The open / close switch 23 is provided on a predetermined portion (not shown) of the vehicle body 1 or the slide door 3, a portable item (not shown) carried together with the ignition key, or the like. When the opening operation signal is input from the opening / closing switch 23, the controller 21 opens the slide door 3 to the fully open position P4, and the closing operation signal is input from the opening / closing switch 23, as shown in FIG. , Sliding door 3
The drive motor 11 is controlled via the drive circuit 24 in order to close the valve to the fully closed position P0. The controller 2
1 also controls a latch drive motor (not shown) that latches and unlatches the slide door 3.

In this embodiment, the drive motor 11 (motor body 13) includes three brushes, a common brush 25a, a low speed brush 25b and a high speed brush 25c. Common brush 25a and low speed brush 2
Although not shown, 5b are arranged at positions facing each other with a rotary shaft (commutator) interposed therebetween, and the high speed brush 25c is arranged at a position rotated by a predetermined angle with respect to the low speed brush 25b. The motor main body 13 is supplied with drive power through the common brush 25a and the low speed brush 25b, or is supplied with drive power through the common brush 25a and the high speed brush 25c. In this case, when drive power is supplied to the motor main body 13 using the low speed brush 25b, the torque-rotation speed characteristic of the motor main body 13 changes on the straight line X1 in FIG. That is, the motor body 1
3 rotates at low speed and high torque. On the other hand, high speed brush 2
When drive power is supplied to the motor main body 13 using 5c, the torque-rotational speed characteristic of the motor main body 13 changes on the straight line X2 in FIG. That is, the motor body 13 rotates at high speed and low torque.

Further, in the drive motor 11, the motor 11
A rotation sensor 26 for detecting the number of rotations is provided.
The rotation sensor 26 outputs an output signal corresponding to the rotation of the drive motor 11 to the controller 21. Controller 2
1 detects the number of rotations of the drive motor 11 based on the output signal from the rotation sensor 26, and detects the opening / closing position of the slide door 3.

As shown in FIGS. 3 and 4, the controller 21 sets the fully closed position P0 to the position P1 immediately before full closing as the latch operation area A0, and the position immediately before fully closed P1 to the fully open position P4 as the slide operation area ( Areas A to C) are set. Further, in this slide operation area, the controller 21 sets the close side predetermined area A near the fully closed position P0 of the slide door 3 and the open side predetermined area C near the fully open position P4 as low speed operation areas, and between the areas A and C. The intermediate area B of is set as the high speed operation area. In the latch operation area A0 from the fully closed position P0 to the position P1 immediately before fully closed,
The controller 21 drives the latch drive motor, and latches and releases the latch of the slide door 3 by the motor.

In the slide operation area (areas A to C), the slide door 3 is moved from the position P1 immediately before fully closed to the fully open position P.
When the opening operation is performed up to 4, the controller 21 determines the closing side predetermined area A from the position P1 immediately before the fully closing to the closing side predetermined position P2.
Is operated at a low speed, is operated at a high speed in the intermediate region B from the closed side predetermined position P2 to the open side predetermined position P3, and is operated at a low speed again in the open side predetermined region C from the open side predetermined position P3 to the fully open position P4. Drive motor 11 (motor body 1
3) is controlled. Also, when the slide door 3 is opened from the fully open position P4 to the position P1 immediately before fully closed,
The controller 21 controls the drive motor 11 (motor body 13) to operate at a low speed in the open side predetermined region C, at a high speed in the intermediate region B, and again at a low speed in the close side predetermined region A. The controller 21 adjusts the opening / closing speed of the slide door 3 in this manner so as to improve the appearance of the opening / closing operation of the door 3.

In this case, when operating the slide door 3 at a low speed, the controller 21 supplies drive power to the drive motor 11 (motor body 13) via the common brush 25a and the low speed brush 25b. Therefore, as described above, the drive motor 11 (motor main body 13) is driven at low speed and high torque, and the slide door 3 operates at low speed. On the other hand, when the slide door 3 is operated at high speed, the controller 21 supplies drive power to the drive motor 11 (motor body 13) via the common brush 25a and the high speed brush 25c. Therefore, as described above, the drive motor 11 (motor main body 13) is driven at high speed and low torque, and the slide door 3 operates at high speed.

Further, when the sliding door 3 is in the closing operation, in the closing side predetermined area A, as shown in FIG. 4, the sliding door 3 is inserted into the vehicle from the front-rear movement of the vehicle body 1. In addition, since a reaction force is received from the weather strip and the door latch mechanism (both not shown), the door 3 requires a relatively large closing force. Therefore,
In this area A, the drive motor 11 (motor body 1
3) is driven at a low speed and high torque to close the sliding door 3, so that a large closing force can be applied to the door 3 and the door 3 can be smoothly moved to the position P1 immediately before the full closing. You can As described above, when the door 3 is located at the position P1 immediately before the fully closed position, the latch drive motor is driven, the door 3 is pulled to the fully closed position P0, and the door 3 is in the latched state.

Further, when the slide door 3 is in the opening operation, in the open side predetermined region C, a reaction force is received from a holding mechanism (not shown) for holding the slide door 3 at the fully open position P4, and therefore, A relatively large opening force is required for the door 3. Therefore, in this region C, the drive motor 11 (motor main body 13) is driven at low speed and high torque to open the slide door 3, so that a large force in the fully opening direction can be applied to the door 3. The door 3 is securely held by the holding mechanism.

A pressure detection signal is input to the controller 21 from the pressure sensor 17 attached to the slide door 3. The controller 21 controls the sensor 1 while the slide door 3 is being closed by the drive motor 11.
When the pressure detection signal from 7 is input, the slide door 3
Since a foreign object is sandwiched between the vehicle and the vehicle body 1,
It is determined that the pressure sensor 17 is externally pressed. When such a trapping determination is made, the controller 21 reversely operates the drive motor 11 to open the slide door 3 in the opening direction by a predetermined operation amount (reverse operation) to remove the pinched foreign matter. Control to open.

At this time, as shown in FIG. 3, when the slide door 3 is closing in the intermediate region B, the door 3 is closing at high speed, so the controller 21
As it is, the drive motor 11 is reversely driven, and the slide door 3
Open at high speed in the opening direction (reverse operation). On the other hand, when the sliding door 3 is closing in the closing side predetermined area A, the door 3 is closing at a low speed, so the controller 21 reversely drives the drive motor 11, and
The low-speed brush 25b is switched to the high-speed brush 25c to supply drive power to the drive motor 11 (motor body 13). That is, the controller 21 drives the drive motor 11 at high speed to open the slide door 3 in the opening direction at high speed (reverse operation). Although not shown, the controller 21 also drives the drive motor 11 at high speed to cause the slide door 3 to move at high speed in the opening direction even when it is determined to be caught in the opening-side predetermined region C where the possibility of jamming is extremely low. It is designed to be opened (reversed). That is, when such trapping occurs, the slide door 3 is always opened (reversed) at a high speed by the control of the controller 21, and the foreign matter trapped by the door 3 is always opened in a shorter time. It is supposed to do.

As described above, the slide door opening / closing device 10 of this embodiment has the following features. (1) In the present embodiment, the controller 21 detects whether or not a foreign object may have been caught between the door 3 and the vehicle body 1 during the closing operation of the slide door 3, and performs the jamming. When detected, the areas A to C where the slide door 3 is located
Regardless of this, the drive motor 11 (motor main body 13) is controlled so as to reverse the door 3 in the opening direction at high speed. That is, even when the sliding door 3 is operating in the closing-side predetermined area A that is a low speed operation area, even if the trapping by the door 3 is detected, the door 3 is reversed at high speed. Therefore, the trapped foreign matter can be always released in a shorter time.

(2) In this embodiment, the pressure sensor 17 is used to detect the trapping, so that the detection can be easily performed. (3) In the present embodiment, the pressure sensor 17 is attached to the front end of the sliding door 3 that operates. Therefore, before the foreign matter is sufficiently clamped between the slide door 3 and the vehicle body 1, the foreign matter is detected by the door 3 (pressure sensor 17).
It is detected that entrapment has occurred at the time of hitting. Therefore, trapping can be detected earlier and the trapped foreign matter can be released in a shorter time.

(4) In this embodiment, the drive motor 11
The (motor main body 13) has a common brush 25a, a low speed brush 25b, and a high speed brush 25c, and the controller 21 uses the common brush 25a and the low speed brush 25b when operating the slide door 3 at a low speed. Drive power is supplied to the drive motor 11 and the slide door 3
When operating at high speed, drive power is supplied to the drive motor 11 via the common brush 25a and the high speed brush 25c. Therefore, it is possible to easily change the rotation speed of the drive motor 11 (change the operating speed of the slide door 3) simply by switching the brushes 25b and 25c that supply the drive power without requiring complicated speed control. You can

When the drive motor 11 is driven at a low speed, the rotation speed of the motor 11 is not only low but also high torque. Therefore, in the closing side predetermined area A, since the sliding door 3 needs a relatively large closing force as described above, the driving motor 11 has a high torque in this area A, so that the sliding door 3 has a large closing force. And the door 3 can be moved smoothly. Further, in the opening side predetermined region C, since a relatively large force in the fully opening direction is required for the slide door 3 as described above, the drive motor 11 has a high torque in this region C, so that the door 3 has a large fully opening direction. A force in the direction can be applied, and the door 3 can be reliably held by the holding mechanism.

(5) In this embodiment, the sliding door 3 is reversed by a predetermined amount during the reversing operation due to the sandwiching. That is, if the sliding door 3 is reversed by a predetermined amount, the foreign matter that has been sandwiched can be sufficiently released, so that the time required for the reverse operation can be shortened.

The embodiment of the present invention may be modified as follows. In the above-described embodiment, the low speed operation area (areas A and C) is provided near the fully closed position P0 and the fully opened position P4 in both opening and closing operations, and the slide door 3 is provided in these areas A and C.
Was set to operate at a low speed. In the closing operation, the speed may be set to be low only in the low speed operation area (area A) near the fully closed position P0, and may be set to be low in only the low speed operation area near the fully open position P4 (area C) in the opening operation. Also, other than this, slide door 3
The low speed operation area and the high speed operation area in the operation area may be changed appropriately.

In the above embodiment, the brushes 25b and 25c for supplying drive power to the drive motor 11 are switched to change the rotation speed of the motor 11 (change the operating speed of the slide door 3). For example, speed control may be performed by further adding PWM control. Alternatively, the speed control may be performed only by the PWM control using a motor having a normal brush configuration that does not use the high speed brush 25c.

In the above embodiment, the pressure sensor 17 is attached to the front end of the slide door 3, but the pressure sensor 17 may be attached to a portion of the vehicle body 1 facing the front end of the door 3. Good. Further, the pressure sensor 17 may be attached to both the slide door 3 and the vehicle body 1.

In the above embodiment, the pressure sensor 17 is used to detect the trapping by the slide door 3. However, the trapping may be detected by using other detecting means.

In the above embodiment, the slide door 3 is reversed by a predetermined amount during the reversal operation due to the sandwiching, but it may be reversed up to the fully open position P4, for example.
