Description

  The present invention relates to a sliding door opening and closing device for an automobile.

  2. Description of the Related Art Some automotive slide door opening / closing devices include an actuator mounted on a vehicle body that automatically opens and closes a slide door that is slidably supported with respect to the vehicle body based on power supply from a battery. In this case, an operation switch for opening and closing the door with an actuator is provided on the vehicle side such as a driver's seat.

  When the door is opened by the operation switch, power is supplied from the battery to the actuator, and the actuator is driven to open. The sliding door is continuously opened from the fully closed state to the fully open state. On the other hand, when the door is closed with the operation switch, power is supplied from the battery to the actuator, and the actuator is driven to open. Then, the sliding door is closed.

  By the way, when the sliding door reaches the intermediate position during the closing operation, the power supply from the battery to the actuator is temporarily cut off to temporarily stop the door. Then, power is supplied to the actuator again, and the door is closed again to control the door to be fully closed.

  With this configuration, the sliding door is temporarily stopped at the intermediate position of the sliding movement and then closed again, so that the operating speed when the door is fully closed is lowered. Therefore, noise such as operation noise and collision noise when fully closed can be suppressed.

  However, in the above-described configuration, as a matter of course, the operation speed and the noise such as the collision sound are not suppressed because the operation speed is not kept low when the sliding door is opened. Even during the closing operation, the sliding door closing operation speed increases again from the middle position of the sliding movement, so it cannot be reliably reduced to a low speed, and noise such as operating noise and collision noise is reliably suppressed. I can't.

  By the way, in the sliding door opening and closing device having the above configuration, the present applicant measured the pinching load acting on the door when an object or the like was pinched between the sliding door and the vehicle body that were closed, and FIG. It was found that a load of 300 N at the maximum acts on the sliding door closing speed (absolute value). Therefore, a large load is applied to the sandwiched object when sandwiched. Therefore, it is necessary to reliably reduce the sliding door closing operation speed to a low speed immediately before the fully closing position.

  Further, since an operation switch for opening and closing the slide door is provided in the driver's seat, the operator must operate at a place different from the manual opening and closing operation of the slide door. Therefore, the operator feels uncomfortable.

  The present invention has been made to solve the above problems, and its purpose is to improve the operability of the automatic opening / closing operation of the sliding door to reduce the operator's uncomfortable feeling and to open / close the sliding door. An object of the present invention is to provide a sliding door opening / closing device for an automobile that can surely reduce the speed to a low speed and reliably suppress noise such as operation noise and collision noise.

  In order to achieve the above object, a sliding door opening and closing device for an automobile according to claim 1 is slidably supported with respect to a vehicle body based on a power supply from a power source mounted on the vehicle. A sliding door opening and closing device for an automobile provided with a sliding driving means for slidingly driving and opening and closing the opening, wherein the sliding door opening and closing device is disposed in a grip portion provided to manually open and close the sliding door, and based on the opening and closing operation A switch for automatically opening and closing the sliding door via the slide driving means, and when the sliding door is automatically opened and closed based on the opening and closing operation of the switch, the door is fully opened or fully opened. A decelerating control means for controlling the slide driving means to decelerate the opening / closing operation speed of the door from a position before reaching the closed state, and the automatic opening / closing Regardless of the maximum speed of the sliding door during the operation, the sliding door is decelerated at a constant acceleration, and the sliding door starts to be decelerated according to the maximum speed so as to reach the fully open or fully closed state at the same speed. Set the position.

  Therefore, according to the first aspect of the present invention, the switch is disposed in the grip portion provided to manually open and close the slide door, and the slide door is automatically opened and closed by the slide driving means based on the opening and closing operation. . The deceleration control means is configured to open and close the door from the position before the door is fully opened or fully closed when the slide door is automatically opened and closed based on the opening and closing operation of the switch. The slide driving means is controlled so as to decelerate. Therefore, since the door can be automatically opened and closed by operating a switch disposed on the grip portion of the slide door, the operator's uncomfortable feeling related to the automatic opening and closing operation can be reduced. In addition, the sliding door has its opening / closing operation speed reduced from a position before reaching the fully open or fully closed state by the deceleration control means and is surely suppressed to a low speed. Noise such as collision noise can be reliably suppressed.

  According to the sliding door opening and closing device for an automobile of the present invention, the operability of the automatic opening and closing operation of the sliding door is improved to reduce the uncomfortable feeling of the operator, and the opening and closing operation speed of the sliding door is surely reduced to a low speed. Therefore, it is possible to reliably suppress noise such as operation noise and collision noise.

Hereinafter, an embodiment of the present invention will be described with reference to FIGS.
FIG. 1 shows a vehicle 1 having a sliding door. The sliding door 2 is supported so as to be slidable in the front-rear direction with respect to the vehicle body 1a, and opens and closes the entrance 1b as an opening of the vehicle by sliding.

  The sliding door 2 detects the operating force exerted on the gripping portion 3a when the passenger opens and closes the sliding door 2 to the gripping portion 3a for performing manual operation provided inside and outside the vehicle. A handle switch 3 is provided as a switch for outputting a detection signal.

  Further, a pressure sensitive switch 4 is attached to the slide door 2 as pressure sensing means for detecting the external force when an external force of a predetermined value or more is applied to the front side 2a. This pressure-sensitive switch 4 is a well-known switch in which an electrode having a predetermined gap is arranged in an elastically deformable rubber tube. When an external force acts on the tube, the electrodes come into contact with each other to detect the external force. It is configured to output a signal. Then, by detecting an external force with the pressure sensitive switch 4, the pinching between the slide door 2 and the vehicle body 1a is detected.

  In the slide door 2, a door lock device 5 for electrically locking and unlocking the door 2 and an in-door controller 6 for controlling the door lock device 5 are disposed. Each detection signal of the handle switch 3 and the pressure sensitive switch 4 is input to the door controller 6.

  A slide drive device 7 as a slide drive means for sliding the slide door 2 is disposed below the vehicle entrance 1b. As shown in FIG. 2, the slide drive device 7 is formed such that its base plate 8 extends in the front-rear direction of the entrance / exit 1b, and is assembled to the vehicle body 1a. A pulley 9 is rotatably attached to the front end portion of the base plate 8. A rotation drive device 10 is assembled to the rear end of the base plate 8.

  As shown in FIG. 3, the rotation drive device 10 includes an electric motor 11, a speed reduction mechanism 12 having a worm and a worm wheel for reducing the rotation of the motor 11, and a rotation shaft that can intermittently rotate the speed reduced by the speed reduction mechanism 12. 13 is constituted by an electromagnetic clutch 14 for transmission to 13. The electromagnetic clutch 14 is in an excited state when automatically opened and closed, and the rotating shaft 13 and the speed reduction mechanism 12 are in a connected state.

  A sprocket 15 is fixed to the rotary shaft 13. The sprocket 15 is formed in a substantially cylindrical shape, and locking projections 15a are formed at equal angular intervals on the outer peripheral surface thereof as shown in FIG.

  An annular drive tape 16 is hung between the sprocket 15 and the pulley 9. The drive tape 16 has locking holes 16a that are engaged with the locking protrusions 15a of the sprocket 15 at regular intervals.

  Specifically, the drive tape 16 is formed in an annular shape by connecting both ends of a tape made of a strip-shaped synthetic resin material with a tension device 17. The tension device 17 applies a predetermined tension to the drive tape 16 so that the drive tape 16 rotates smoothly between the sprocket 15 and the pulley 9.

  A lower roller 17 a is integrally connected and fixed to the tension device 17. In the longitudinal direction of the base plate 8, a guide rail 8a for guiding the movement of the lower roller 17a is formed. The lower roller 17a is connected to a door stay 2b provided at the lower part of the slide door 2.

  Then, when the electromagnetic clutch 14 is in an excited state and the rotary shaft 13 and the speed reduction mechanism 12 are in a connected state, when the electric motor 11 rotates to open the slide door 2, the counterclockwise direction in FIG. The sprocket 15 rotates at the same time, and the drive tape 16 rotates in the same direction as the rotation. Then, as the drive tape 16 rotates, the lower roller 17a moves rearward along the guide rail 8a to open the slide door 2.

  On the contrary, when the electric motor 11 rotates to close the sliding door 2, the sprocket 15 rotates in the clockwise direction in FIG. 2, and the drive tape 16 rotates in the same direction along with the rotation. Then, as the drive tape 16 rotates, the lower roller 17a moves forward along the guide rail 8a to close the slide door 2.

  When the electromagnetic clutch 14 is in a non-excited state and the rotating shaft 13 and the speed reduction mechanism 12 are in a non-connected state, the lower roller 17a is moved along the guide rail 8a when the sliding door 2 is manually opened. Then, the drive tape 16 and the sprocket 15 are rotated counterclockwise in FIG.

  On the contrary, when the slide door 2 is manually closed, the lower roller 17a moves forward along the guide rail 8a, and the drive tape 16 and the sprocket 15 rotate in the clockwise direction in FIG.

  As shown in FIGS. 3 and 4, the sprocket 15 is provided with a winding portion 18 having the same diameter as the sprocket 15. The winding unit 18 winds a flexible flat cable (hereinafter referred to as a flat cable) 19 along with the rotation of the sprocket 15. The flat cable 19 is provided with a power supply line and a signal line.

  More specifically, as shown in FIG. 5, the take-up portion 18 is provided with a cylindrical take-up drum 18a that rotates with the rotation of the sprocket 15, and is disposed in the take-up drum 18a to the vehicle body 1a. And a fixed cylindrical drum 18b.

  A connector 19a provided at one end of the flat cable 19 is inserted and fixed to a fixed drum 18b. One end of the flat cable 19 is connected to a battery (12 volts) 20 as a power source provided in the vehicle shown in FIG. 1 via a connector 19a and a deceleration control means, a speed increase control means, and a closing operation for controlling the rotary drive device 10. It is connected to a slide door controller 21 as control means.

  In a space 18c between the fixed drum 18b and the take-up drum 18a, a take-up adjusting cable portion 19c in which the flat cable 19 is spirally wound around the fixed drum 18b is provided. Is fixed to the winding fixing portion 18d. The flat cable 19 is led out from the winding fixing portion 18d to the outer periphery of the winding drum 18a. A connector 19 b provided at the other end of the flat cable 19 is inserted and fixed to the tension device 17. The connector 19b inserted into the tension device 17 is wired in the slide door 2 along the tension device 17 and the door stay 2b, and is connected to the door controller 6. That is, the other end of the flat cable 19 is connected to the in-door controller 6 via the connector 19b.

  In this way, the door controller 6 on the slide door 2 side, the battery 20 on the vehicle body 1a side, and the slide door controller 21 are electrically connected to each other so that power supply and signal exchange are possible. ing. In the present embodiment, the door lock device 5 and the pressure-sensitive switch are supplied with power through the door controller 6 in the present embodiment.

  When the slide door 2 is in the fully closed state, the winding unit 18 configured as described above is in a state in which the flat cable 19 is extended as shown in FIG. 5, and the winding adjustment cable unit inside the winding drum 18a. 19c is tightly wound around the fixed drum 18b.

  When the sliding door 2 is opened, the sprocket 15 rotates counterclockwise in FIG. 5 as described above, and the winding drum 18a integrally formed with the same diameter as the sprocket 15 also rotates in the same direction. . Then, as shown in FIG. 6, the flat cable 19 is wound around the outer periphery of the winding drum 18a. At this time, since the sprocket 15 and the winding drum 18a have the same diameter, the lower roller 17a and the connector 19b of the flat cable 19 to be inserted and fixed to the tension device 17 connected to the lower roller 17a are: The moving speeds associated with the opening operation of the sliding door 2 are substantially the same.

  On the other hand, within the winding drum 18a, the winding adjusting cable portion 19c tightly wound around the fixed drum 18b gradually loosens as the winding drum 18a rotates counterclockwise. Eventually, when the slide door 2 is fully opened, the winding adjustment cable portion 19c is completely loosened with respect to the fixed drum 18b as shown in FIG.

  On the contrary, when the sliding door 2 is closed, the sprocket 15 rotates in the clockwise direction in FIG. 7 as described above, and the winding drum 18a also rotates in the same direction. Then, as shown in FIG. 6, the flat cable 19 is rewound on the outer periphery of the winding drum 18a. At this time, since the sprocket 15 and the winding drum 18a have the same diameter, the lower roller 17a and the connector 19b of the flat cable 19 to be inserted and fixed to the tension device 17 connected to the lower roller 17a are: The moving speeds accompanying the closing operation of the slide door 2 are substantially the same.

  On the other hand, in the winding drum 18a, the winding adjusting cable portion 19c that is loose with respect to the fixed drum 18b gradually becomes denser as the winding drum 18a rotates in the clockwise direction. Eventually, when the slide door 2 is fully closed, the winding adjustment cable portion 19c is completely and tightly wound around the fixed drum 18b as shown in FIG.

  That is, the winding unit 18 winds and unwinds the flat cable 19 at the same speed as the opening / closing operation speed in the opening / closing operation of the slide door 2, and thus prevents the cable 19 from being bent excessively. It has become.

  As shown in FIG. 3, a rotation sensor 22 that detects the number of rotations of the rotation shaft 13 is disposed on the rotation shaft 13. The rotation sensor 22 outputs a pulse signal synchronized with the rotation of the rotating shaft 13 to the sliding door controller 21.

  Further, in addition to the handle switch 3, a switch for operating the rotary drive device 10 is a driver seat side opening / closing switch 23 in the vicinity of the driver seat as shown in FIG. An open / close switch 24 is provided. Both switches 23 and 24 respectively output an opening / closing command signal to the sliding door controller 21.

Next, control of the slide door controller 21 will be described with reference to FIG.
The sliding door controller 21 detects the position of the sliding door 2 by counting the pulse signal of the rotation sensor 22. That is, even if it is either “automatic” or “manual”, the rotary shaft 13 rotates with the opening and closing of the slide door 2, and therefore the slide door controller 21 detects the rotation of the rotary shaft 13 from the rotation sensor 22. Counting is performed based on the synchronized pulse signal, and the position of the sliding door 2 is always detected.

  When a lock command signal is input to the slide door controller 21 to lock the slide door 2 from a door lock switch (not shown), the slide door controller 21 locks the door lock device 5 via the in-door controller 6 connected to each other by the flat cable 19. Operate.

  When the sliding door 2 is automatically closed by the rotary drive device 10, the sliding door controller 21 applies an external force of a predetermined value or more to the pressure sensitive switch 4, and an external force detection signal based on the external force is output from the door internal controller. 6, it is determined that something has been sandwiched between the door 2 and the vehicle body 1a. Then, the slide door controller 21 drives the electric motor 11 of the rotation drive device 10 to rotate in the reverse direction for a predetermined time, and opens the slide door 2 by a predetermined amount.

  When an operation force detection signal for detecting the operation force is input from the handle switch 3 provided in the grip portion 3a via the door controller 6, the slide door controller 21 moves the slide door 2 by the rotary drive device 10. Open and close. That is, when the passenger gets in the opening operation of the fully closed slide door 2 by the grip portion 3 a, the slide door controller 21 uses the rotary drive device 10 to move the slide door based on the operation force detection signal from the handle switch 3. 2 is opened. On the other hand, when the passenger gets to close the slide door 2 that is fully opened by the grip portion 3 a, the slide door controller 21 uses the rotary drive device 10 to move the slide door 2 based on the operation force detection signal from the handle switch 3. Is closed.

  Further, the slide door controller 21 opens and closes the slide door 2 via the rotation drive device 10 based on the opening / closing command signals from the driver seat side opening / closing switch 23 and the entrance / exit side opening / closing switch 24.

  Further, the slide door controller 21 is provided with a timer 21a, which measures the time based on the start of the automatic opening / closing operation of the slide door 2, that is, based on the input of the operation force detection signal from the handle switch 3. .

  The sliding door controller 21 detects the voltage of the battery 20 from time to time, and controls the speed of the electric motor 11 based on the voltage value. The slide door controller 21 performs speed control of the electric motor 11 of the rotary drive device 10 by pulse width modulation (PWM). The sliding door controller 21 stores in advance an opening / closing operation speed map of the door 2 with respect to the position of the sliding door 2 as shown in FIGS. 9A and 9B, and the controller 21 follows the speed map. The rotational speed of the electric motor 11 is controlled so as to open and close. In this embodiment, the maximum speed is set in the speed map corresponding to the voltage value of the battery 20. This is because the battery 20 (12 volts) fluctuates in the range of about 8 to 16 volts depending on the state of the situation, so the maximum speeds v1 to v3 are preset for 8 to 16 volts.

  That is, in this embodiment, when the voltage value of the battery 20 is in a normal state (for example, 10 volts or more and less than 14 volts), the maximum speed in the opening / closing operation of the slide door 2 is set to “v2” in advance. Yes. Further, when the voltage value of the battery 20 is lower than the normal state (for example, not less than 8 volts and less than 10 volts), the maximum speed v1 that is slower than the maximum speed v2 is set in advance. Further, when the voltage value of the battery 20 is higher than the normal state (for example, 14 volts or more and less than 16 volts), the maximum speed v3 that is faster than the maximum speed v2 is set in advance.

  Further, as shown in FIG. 9A, at the start of the opening operation of the sliding door 2, the sliding door controller 21 makes the inclination of the operating speed of the sliding door 2 constant “a1” regardless of the voltage value of the battery 20. Slow start speed control to increase speed is performed. Then, the controller 21 performs the slow start speed control until the operating speed of the slide door 2 reaches the maximum speeds v1 to v3 corresponding to the voltage value of the battery 20, that is, for the time t1 to t3.

Next, after performing the slow start speed control, the slide door controller 21 opens the slide door 2 at the maximum speeds v1 to v3 corresponding to the voltage value of the battery 20.
Eventually, when the sliding door 2 in the opening operation reaches positions P1 to P3 corresponding to the voltage values of the battery 20 (maximum speeds v1 to v3 of the sliding door 2), the sliding door controller 21 tilts the operating speed of the sliding door 2. Regardless of the voltage value of the battery 20 (the maximum speeds v1 to v3 at that time), slow stop speed control is performed to decelerate at a constant "a2". The positions P1 to P3 are set in advance corresponding to the voltage value of the battery 20, and are included in the speed map. Then, the slide door 2 reaches a fully open state.

  On the other hand, as shown in FIG. 9B, at the start of the closing operation of the sliding door 2, the sliding door controller 21 determines that the inclination of the operating speed of the sliding door 2 is the voltage value of the battery 20 as in the above opening operation. Regardless of this, slow start speed control is performed to increase the speed at a constant “a1”. Then, the controller 21 performs the slow start speed control until the operating speed of the slide door 2 reaches the maximum speeds v1 to v3 corresponding to the voltage value of the battery 20, that is, for the time t1 to t3.

Next, after performing the slow start speed control, the slide door controller 21 closes the slide door 2 at the maximum speeds v1 to v3 corresponding to the voltage value of the battery 20.
Eventually, when the sliding door 2 during the closing operation reaches positions P4 to P6 corresponding to the voltage values of the battery 20 (maximum speeds v1 to v3 of the sliding door 2), the sliding door controller 21 tilts the operating speed of the sliding door 2. Regardless of the voltage value of the battery 20 (the maximum speeds v1 to v3 at that time), slow stop speed control is performed to decelerate at a constant "a2". The positions P4 to P6 are set in advance corresponding to the voltage value of the battery 20, and are included in the speed map. Then, when the operating speed of the slide door 2 reaches the minimum speed v0, the controller 21 makes the speed v0 constant. The minimum speed v0 is the minimum speed at which the slide door 2 reaches the fully closed state against a reaction force of a door latch device or a weather strip (not shown). Thereafter, the slide door 2 reaches a fully closed state.

  Thus, the sliding door 2 whose opening / closing speed is controlled by the sliding door controller 21 has the speed at the time of slow start and slow stop of the slide door 2 regardless of the voltage value of the battery 20 (each maximum speed v1 to v3). It is opened and closed with a constant inclination, that is, with a constant acceleration. Therefore, the uncomfortable feeling for the operator is reduced.

  Further, the slide door 2 is slow-stopped when fully opened or fully closed, and the acceleration is constant regardless of the voltage value of the battery 20, so that even if the voltage value of the battery 20 fluctuates, the slide door 2 is fully opened or fully opened. The operation speed is reduced until the closed state is reached, and the speed is surely kept low. Therefore, noise such as operation noise and collision noise when the slide door 2 is fully opened or fully closed is reliably suppressed.

  Further, since the acceleration at the time of slow stop is made constant regardless of the voltage value of the battery 20, the feeling of detecting pinching between the door 2 and the vehicle body 1a at the time of slow stop of the sliding door 2 during the closing operation. A constant pinching load (external force) is always applied to the pressure switch 4. For this reason, in the present embodiment, the sliding door controller 21 reliably determines the pinching.

As described above, the present embodiment has the following characteristics.
(1) The handle switch 3 is disposed in a grip portion 3a provided inside and outside the slide door 2 respectively. Then, the slide door 2 is automatically opened and closed by the slide drive device 7 by operating the handle switch 3 disposed in the grip portion 3a. Therefore, it is possible to reduce the operator's uncomfortable feeling related to the automatic opening / closing operation of the slide door 2. In addition, the operability of the slide door 2 can be improved.

  (2) The slide door controller 21 controls the rotation of the electric motor 11 of the rotary drive device 10 by the pulse width modulation method, and the battery 20 from positions P1 to P6 before the slide door 2 reaches the fully open or fully closed state. The opening / closing operation speed of the door 2 is decelerated, that is, a slow stop operation is performed so that the acceleration is constant regardless of the voltage value of. Therefore, since the operation speed is decelerated until the sliding door 2 reaches the fully open or fully closed state regardless of the voltage value of the battery 20 and is surely suppressed to a low speed, the door 2 is fully opened or fully closed. It is possible to reliably suppress the noise such as the operation sound and the collision sound.

  (3) Also, the slide door controller 21 has a minimum speed v0 that is just before the slide door 2 reaches the fully closed state against the reaction force of the door latch device, weatherstrip, etc. immediately before the slide door 2 is fully closed. To control. Therefore, since the slide door 2 can be more reliably suppressed to a lower speed immediately before the fully closed state, it is possible to reliably suppress noise when the door is fully closed.

  (4) The slide door controller 21 controls the rotation of the electric motor 11 of the rotary drive device 10 and starts from the start of the opening / closing operation of the slide door 2 until a predetermined time t1 to t3 (maximum with respect to the voltage value of the battery 20 at that time). The opening / closing operation speed of the door 2 is increased, that is, the slow start operation is performed so that the acceleration is constant regardless of the voltage value of the battery 20 (until the speeds v1 to v3 are reached). Accordingly, by causing the sliding door 2 to perform a slow start operation, the door 2 operates in the same manner as the manual opening / closing operation, so that the operator's uncomfortable feeling during the automatic opening / closing operation can be reduced.

  (5) A pressure-sensitive switch 4 is attached to one side 2a in front of the slide door 2, and the pressure-sensitive switch 4 detects an external force when an external force exceeding a predetermined value is applied to the door 2. A detection signal is output to the sliding door controller 21. When the slide door controller 21 detects an external force of a predetermined value or more with the pressure sensitive switch 4, the slide door controller 21 stops the further closing operation of the slide door 2 that is closed with the slide drive device 7 and opens the door 2. Open the specified amount. Accordingly, it is possible to prevent the pinching between the slide door 2 and the vehicle body 1a.

  (6) Moreover, since the pressure-sensitive switch 4 is provided on the slide door 2 side, it can easily react to an external force, so that the pinching between the slide door 2 and the vehicle body 1a can be reliably performed beforehand. Can be prevented.

  (7) The driving tape 16 has locking holes 16a formed at equal intervals so as to transmit the rotational force of the sprocket 15. Therefore, the drive tape 16 can be formed more easily than a toothed shape, and can be formed at a low cost.

  (8) In the present embodiment, by providing the flat cable 19 and the winding unit 18 of the rotary drive device 10, the vehicle body side electric power can be used regardless of whether the slide door 2 is in the open state or the closed state. Devices (slide door controller 21, rotation drive device 10, etc.) and slide door side electrical devices (door controller 6, handle switch 3, pressure sensitive switch 4, etc.) can always be connected.

(9) The flat cable 19 can be attached by the connectors 19a and 19b. Therefore, the attachment work can be facilitated.
(10) The flat cable 19 is wound up or rewound in synchronization with the opening and closing movement of the slide door 2 at the winding unit 18. Accordingly, since the flat cable 19 is not pulled excessively and is prevented from being excessively bent, the flat cable 19 does not hinder the opening / closing operation of the slide door 2.

In addition, this invention is not limited to the said form, You may make it as follows in the range which does not deviate from the meaning of this invention.
In the above embodiment, the door lock device 5, the pressure sensitive switch 4, the handle switch 3, and the in-door controller 6 are mounted as electric devices in the slide door 2, but other electric devices such as a door closer device and a power window device are used. Equipment may be installed.

  In the above embodiment, the slide door controller 21 sets the acceleration of the opening / closing operation speed of the slide door 2 during the slow stop operation regardless of the voltage value of the battery 20, but it may not be constant. Even if it does in this way, since the operation speed is decelerated by the time when the slide door 2 is fully opened or fully closed, and it is surely suppressed to a low speed, the operation sound or collision when the slide door 2 is fully opened or fully closed Noise such as sound can be suppressed.

  In the above embodiment, the maximum speed is set to three stages of v1 to v3 with respect to the voltage value of the battery 20, but may be set to two stages or multiple stages of four stages or more. Alternatively, the maximum speed may be set one to one for each voltage value.

In the above embodiment, the slide door controller 21 is set to the minimum speed v0 constant immediately before the slide door 2 is fully closed, but there is no need to provide a section where the minimum speed v0 is constant.
In the above embodiment, the slide door controller 21 sets the acceleration of the opening / closing operation speed of the slide door 2 at the time of the slow start operation regardless of the voltage value of the battery 20, but may not be constant. Further, the slow start operation may not be performed.

  In the above embodiment, the pressure sensitive switch 4 is provided and the sliding door controller 21 detects the pinching between the sliding door 2 and the vehicle body 1a, but the pressure sensitive switch 4 is omitted. You may make it impossible to detect a pinch.

  In the above embodiment, the slide door controller 21 controls the rotation of the electric motor 11 by the pulse width modulation (PWM) method, but the rotation of the electric motor 11 may be controlled by other methods.
