BACKGROUND OF THE INVENTION
The present invention relates to an automatic sliding door control device that operates a sliding door.
[0002]
[Prior art]
2. Description of the Related Art Conventionally, a vehicle is provided with a slide door that opens and closes a door opening, and an automatic slide door control device that electrically opens and closes the slide door is equipped.
[0003]
Further, when the slide door is fully closed, a latch provided on the slide door side is hooked on a striker provided on the vehicle body side, thereby restraining the slide door in the fully closed position. The latch is provided with a locking piece that prevents the latch from rotating and holds the state in which the latch is latched on the striker. This latching piece is connected to the latch release actuator, and when the slide door is opened, the latch release actuator pivots and retracts the latch piece to a position allowing the latch to rotate, and the latch moves in the opening direction of the slide door. By this, the latch is released so that it can be rotated so as to be removed from the striker. And by this latch release, the restrained state in the fully closed position of the slide door is released, and the slide door can be opened.
[0004]
The automatic sliding door control device outputs a latch release command to the latch release actuator when it receives an opening operation command from a switch provided in the driver's seat or a remote control switch, and slides by the latch release actuator. Release the restraint state of the door. Then, the door switch detects that the sliding door has moved from the fully closed position in the opening direction, and after detecting the door opening, the drive motor is opened and the clutch is connected to open the sliding door. Is configured to do.
[0005]
[Problems to be solved by the invention]
However, in such a control method, when the door switch cannot detect the door opening due to malfunction such as a return failure due to freezing, disconnection or astringency, and the door opening judgment cannot be made, the automatic sliding door The opening operation by the drive is not started.
[0006]
In this case, the slide door that can be moved is released from the restrained state by the latch release actuator, and may move in the opening direction due to the dead weight of the sliding door when, for example, the vehicle is stopped on a slope where the opening direction is lowered. If the slope is steep, there is a risk of rapid opening.
[0007]
The present invention has been made in view of such a conventional problem, and provides an automatic sliding door control device capable of eliminating problems that may occur when a door switch that detects door opening causes a malfunction. It is intended to do.
[0008]
[Means for Solving the Problems]
  In order to solve the above-mentioned problem, in the automatic sliding door control device according to claim 1 of the present invention, based on the opening operation command, after releasing the restraint state of the sliding door by the latch release actuator, the door is opened by the door switch. In the automatic slide door control device that opens the drive motor by opening the drive motor while opening the drive motor, and transmitting the drive force from the drive motor or disconnecting the transmission and connecting the clutch. After releasing the restraint state of the sliding door based on the operation command, when the door opening by the door switch is not detected, the clutch isA low output opening operation means for opening the slide door by driving the drive motor at a low output while being in a connected state is provided.
[0011]
That is, when an opening operation command is received by a switch operation or the like, the restraint state of the slide door is released by the latch release actuator based on the opening operation command. At this time, if the door opening by the door switch cannot be detected, the clutch for transmitting or disconnecting the driving force from the driving motor is brought into the connected state, the driving motor is driven at a low output, and the sliding door Is open at low power. As a result, the drive force from the drive motor is low even when the door stops in the downhill direction, so the door opening operation is performed at a low speed, and this low speed door opening operation is rapidly performed by the weight of the slide door. Acts as a brake on the movement of the sliding door to open.

Is configured to do. The slide door movement sensor 223 detects the speed and position of the slide door 4 from the rotation speed of the encoder 81, and outputs a signal when the slide door 4 reaches the fully open or fully closed position. An inversion detection output 226 to be performed and a GND line 227 serving as a ground for voltage matching with the microcomputer M are provided and connected to the automatic sliding door unit 201.
[0031]
Further, the automatic sliding door unit 201 includes a parking switch 231 that is turned on when a parking brake is operated, a slide door opening switch 232 that is operated when the sliding door 4 is opened, and a closing operation. Are connected to a slide door closing switch 233 that is operated by the sliding door switch 234 and a sliding door switch 234 that is turned off when the sliding door 4 is fully closed, and supplies power to the closure unit 21. First and second supply outputs 235 and 236 to be performed are connected to the supply terminal 24.

[0032]
The control unit 251 of the closure unit 21 that receives power supply from the supply terminal 24 drives a latch (not shown) provided on the slide door 4 that is hooked to a striker (not shown) provided on the vehicle body side. The latch release actuator 252 for releasing the latch latched state and the half lock state immediately before the latch is latched by the striker when the slide door 4 is closed from the open state and moved to a position immediately before the fully closed state. A half switch 253 that operates by detecting (half-latch) and a full-lock switch 254 that operates by detecting a full-lock state in which the latch is hooked to the striker are connected. Further, the closure unit 21 is operated when the half-lock state is detected, and the latch is rotated so that the latch is hooked on the striker, thereby pulling the slide door 4 to the full-lock state. A door closure motor 255 is connected. Further, a neutral switch 256 is provided that operates by detecting the neutral state of the closure in a state where the closure motor 255 has returned to the original position (neutral position) before the operation.
[0033]
Further, as described above, when the slide door is fully closed, the unillustrated latch provided on the slide door 4 side is hooked on the striker not shown provided on the vehicle body side, and the slide door 4 is restrained to the fully closed position. is doing.
[0034]
This latch is provided with a locking piece (not shown) that prevents the latch from rotating and holds the state in which the latch is latched on the striker. The latching piece is connected to the latch release actuator 252, and when the slide door 4 is opened, the latch release actuator 252 causes the latching piece to rotate back to a position that allows the latch to rotate, and the latch slides. By the movement of the door 4 in the opening direction, the latch is released so that it can be rotated so as to be detached from the striker. And by this latch release, the restrained state in the fully closed position of the slide door 4 is released, and the slide door 4 can be opened.
[0035]
The vehicle 1 includes a known room lamp that is turned on when the slide door 4 is opened and turned off when the slide door 4 is fully closed. The room lamp is in the state of the slide door switch 234. It is configured to be turned on / off accordingly.
[0036]
In the present embodiment having the above-described configuration, the operation in which the slide door 4 is opened from the fully closed position will be described with reference to the flowchart shown in FIG.
[0037]
That is, when the slide door 4 is restrained by the latch that is hooked on the striker at the fully closed position, the operation of the slide door opening switch 232 provided on the instrument panel in front of the driver's seat or the opening switch of the remote control is operated. It is determined whether or not (keyless operation) has been performed (S1), and if it has not been operated, the process returns to the main routine. If it has been operated, the closure unit 21 is released to release the restraint of the slide door 4. A latch release command is output to the latch release actuator 252, and the time measurement by the latch release timer that has been set for a predetermined time is started (S2), and the process waits until the time measurement by the latch release timer is completed (S2). S3). In the closure unit 21 that has received the latch release command, the latch release actuator 252 is operated to drive the latch piece of the latch provided on the slide door 4 side that is hooked to the striker provided on the vehicle body side. The latch is allowed to rotate, and the latched state is released. Thereby, the restraint state of the slide door 4 is cancelled | released.
[0038]
Here, the predetermined time set in the latch release timer is the time required from the start of the operation of the latch release actuator 252 of the closure unit 21 until the release of the latch by the latch release actuator 252 is completed. Can be mentioned. Thus, it is possible to prevent the determination in the next step S4 from being performed before the latch is released.
[0039]
In step S4, whether or not the slide door switch 234, which is a door switch, is ON, indicates that the slide door 4 restrained in the fully closed position has moved in the opening direction due to the reaction force of the weather strip or the like. It is determined whether or not is detected. When the opening of the door is detected by the sliding door switch 234, the electromagnetic clutch 64 is connected and the output to the drive motor 72 is adjusted to perform a constant speed control for opening the sliding door 4 at a constant speed. (S5). On the other hand, when the sliding door switch 234 remains off in step S4 and the door opening cannot be detected, intermittent clutch control is performed (S6).
[0040]
Specifically, after the electromagnetic clutch 64 is connected and disconnected, the connection is again performed and disconnected. This is repeated, and a timer outside the drawing is operated and executed for the time required for the slide door 4 to reach the fully open position. The set time of this timer is determined by experiment. And the interruption of the electromagnetic clutch 64 is terminated in the disconnected state. Thereby, when the electromagnetic clutch 64 is in the connected state, the mechanical load of the drive transmission mechanism 75 that transmits the driving force of the drive motor 72 can be applied to the slide door 4, and when the electromagnetic clutch 64 is in the disconnected state, At the time of stopping on the slope road that is lowered in the opening direction, the load is not applied to the sliding door 4, so that the sliding door 4 can be moved by its own weight in the opening direction.
[0041]
Thus, when the restraint state of the sliding door 4 is released based on the opening operation command, the door opening cannot be detected due to the failure of the sliding door switch 234, and the constant speed control in the opening direction of the sliding door 4 (S5). Even when the operation is not started, it is possible to intermittently apply a mechanical load to the slide door 4 by intermittently engaging the electromagnetic clutch 64.
[0042]
Accordingly, even when the sliding door 4 moves in the opening direction due to its own weight, such as when the door stops in a slope, the load is applied when the electromagnetic clutch 64 is connected. The movement is braked and can be moved to the fully open position at a low speed. Further, even on a steep slope, the rapid opening movement of the sliding door 4 is suppressed, and the sliding door 4 can be gradually moved to the full opening. Therefore, it is possible to eliminate a problem that may occur when the sliding door switch 234 is defective.
[0043]
When the vehicle stops on a flat road or when the vehicle stops on a hill with the door open, the slide door 4 does not move in the open direction due to the weight of the slide door 4, so the slide door 4 stops in an unlatched state. is doing.
[0044]
At this time, when the electromagnetic clutch 64 is engaged, the load is intermittently applied to the slide door 4, but when the electromagnetic clutch 64 is disconnected, the load is not applied. For this reason, while the electromagnetic clutch 64 is disengaged, it is intermittently opened and closed manually. Further, as described above, the on / off control (S6) of the electromagnetic clutch 64 is ended in the disconnected state, so that it can be manually opened and closed after the control.
[0045]
(Second Embodiment)
[0046]
Hereinafter, a second embodiment of the present invention will be described with reference to the drawings. Since the configuration is the same as that of the first embodiment, a description thereof will be omitted, and only the operation of this embodiment will be described according to the flowchart shown in FIG.
[0047]
That is, when the slide door 4 is restrained by the latch that is hooked on the striker at the fully closed position, the operation of the slide door opening switch 232 provided on the instrument panel in front of the driver's seat or the opening switch of the remote control is operated. It is determined whether or not (keyless operation) has been performed (SC1). If not operated, the process returns to the main routine. On the other hand, if operated, the closure unit 21 is released to release the restraint of the slide door 4. A latch release command is output to the latch release actuator 252, and the time measurement by the latch release timer that has been set for a predetermined time is started (SC2), and the process waits until the time measurement by the latch release timer ends ( SC3). In the closure unit 21 that has received the latch release command, the latch release actuator 252 is operated to drive the latch piece of the latch provided on the slide door 4 side that is hooked to the striker provided on the vehicle body side. Allow the latch to turn and release the latched state. Thereby, the restraint state of the slide door 4 is cancelled | released.
[0048]
Here, the predetermined time set in the latch release timer is the time required from the start of the operation of the latch release actuator 252 of the closure unit 21 until the release of the latch by the latch release actuator 252 is completed. Can be mentioned. Thus, it is possible to prevent the determination at the next step SC4 from being performed before the latch is released.
[0049]
In step SC4, whether or not the slide door switch 234, which is a door switch, is on, indicates that the slide door 4 restrained in the fully closed position has moved in the opening direction due to the reaction force of the weather strip or the like. It is determined whether or not is detected. When the opening of the door is detected by the sliding door switch 234, the electromagnetic clutch 64 is connected and the output to the drive motor 72 is adjusted to perform a constant speed control for opening the sliding door 4 at a constant speed. (SC5). On the other hand, if the sliding door switch 234 remains off in step SC4 and the door opening cannot be detected, the sliding door rotation sensor 223 can be detected by the change in the cumulative number of pulses obtained by adding / subtracting the pulses from the sliding door rotation sensor 223. It is determined whether the door 4 has moved in the opening direction (SC6). If it is not moving in the opening direction, the sliding door 4 is stopped, and parking is possible on a flat ground. Since the slide door 4 may be moving in the opening direction due to the weight of the slide door 4 at the time of stopping on the slope down in the direction, low output opening operation control is performed (SC7).
[0050]
This low power opening operation control is performed by operating and executing a timer outside the time chart required for the slide door 4 to reach the fully open position, and this timer setting time is determined by experiments. And in the fully open position, the electromagnetic clutch 64 is made into a disconnection state. In this low output opening operation control, the electromagnetic clutch 64 is brought into a connected state, a driving pulse having a low duty ratio is output to the driving motor 72, and the driving motor 72 is driven in the opening direction with a low output. Then, when the hill is stopped in the opening direction, the driving force from the driving motor 72 is low output, so the door opening operation is performed at a low speed. This low-speed door opening operation acts as a brake on the movement of the slide door 4 that is about to open rapidly due to its own weight.
[0051]
Thus, when the restraint state of the sliding door 4 is released based on the opening operation command, the door opening cannot be detected due to the failure of the sliding door switch 234, and the constant speed control in the opening direction of the sliding door 4 (SC5). Even if the operation is not started, the sliding door 4 can be opened at a low speed by driving the drive motor 72 at a low output with the electromagnetic clutch 64 connected. As a result, the low-speed driving force of the driving motor 72 can act as a brake when the vehicle stops on the slope that has been lowered in the opening direction.
[0052]
Therefore, even when the sliding door 4 moves in the opening direction due to the weight of the sliding door 4 when the door is open on the slope, the sliding door 4 moves in the opening direction at a moderate speed. Can move. Moreover, even if it is a steep slope, the rapid opening movement of the slide door 4 is suppressed, and it can move to a full opening at a moderate speed. Therefore, it is possible to eliminate a problem that may occur when the sliding door switch 234 is defective.
[0053]
Note that when the vehicle stops on a flat road or when the vehicle stops on a slope down in the door closing direction, since the movement in the door opening direction is not detected in step SC6, the slide door 4 is stopped in the unlatched state. At this time, since the electromagnetic clutch 64 is in a disconnected state, it can be manually opened and closed.
[0054]
【The invention's effect】
  As described above, the present inventionNoIn the case of the sliding door control device, when the sliding door is released from the restraint state based on the opening operation command, the door opening cannot be detected due to a defective door switch or the like, and the sliding door opening control is not started. Also,The sliding door can be opened at a low speed by driving the drive motor at a low output with the clutch engaged. As a result, the low-speed driving force of the drive motor can act as a brake when the vehicle stops on the slope that has been lowered in the opening direction.
[0055]
  Therefore, even when the sliding door is moved in the opening direction due to the weight of the sliding door, such as when stopping on a slope with the door opening direction falling,The sliding door can be moved in the opening direction at a moderate speed. Moreover, even if it is a steep slope, the rapid opening movement of a sliding door is suppressed and it can move to a full opening at a moderate speed. Therefore, it is possible to eliminate problems that may occur when the door switch is defective.
