When the door opening operation input is input from the wireless remote control key or the like when the sliding door is in the fully closed state, the door opening / closing control device operates the release actuator to open the sliding door from the fully closed state. After shifting to the possible state, the door opening / closing device is operated to open the sliding door. On the other hand, when the door closing operation input is input from the wireless remote control key or the like when the sliding door is in the fully open state, the door opening / closing control device operates the release actuator to close the sliding door from the fully open state. Then, the door opening / closing device is operated to close the slide door.

  By the way, a door opening / closing device having a power shut-off means that shuts off the power transmission between the drive source and the drum and manually opens and closes the slide door has been proposed. According to this door opening / closing device, in the event of an emergency such as when the door opening / closing device breaks down, the power transmission from the driving source to the drum is interrupted to interrupt the power transmission from the driving source to the slide door, and the slide is manually performed. The door can be opened and closed (see, for example, Patent Document 1).

JP 2004-36326 A

  However, after the power transmission from the drive source to the sliding door is cut off with the sliding door of the vehicle parked on the slope fully opened or fully closed, the door operation input (door closing operation input or When the door opening operation input is input, the door opening / closing control device operates the release actuator to shift the sliding door to an openable / closable state (closeable state or openable state). There was a risk of blocking or opening and causing an unexpected accident.

  In view of the above circumstances, the present invention has an object to provide a door opening / closing control device capable of suppressing a risk associated with opening / closing of a door even when power transmission from a drive source such as a motor to the door is interrupted. And

  In order to achieve the above object, a door opening / closing control device according to claim 1 of the present invention provides a power source between a drive source and a drum that winds one of a pair of wires connected to the door and winds the other. In the door opening / closing control device for controlling the door opening / closing device provided with the blocking means to control opening / closing of the door, when the power blocking state detecting means for detecting the power blocking state of the power blocking means is provided and the power blocking state is detected The door opening / closing control is invalidated.

  According to a second aspect of the present invention, there is provided a door opening / closing control device that controls a release actuator that releases a meshing state with a striker to release the meshing state between the striker and the latch, and then one of a pair of wires connected to the door. In a door opening / closing control device that opens and closes a door by controlling a door opening / closing device provided with a power cutoff means between a drum that winds up and winds the other and a drive source, the power cutoff state of the power cutoff means is detected A power cutoff state detection means is provided, and the control of the release actuator is invalidated when the power cutoff state is detected.

In the door opening / closing control apparatus for acquiring door position information based on driving information of the driving source, a power shut-off state detecting means for detecting the power shut-off state of the power shut-off means is provided, and the door position is detected when the power shut-off state is detected. It is characterized by invalidating information.

  Since the door opening / closing control device according to the present invention invalidates the door opening / closing control when the power shut-off state is detected, the door does not operate even if a door operation input is input in the power shut-off state. Risk associated with opening and closing can be reduced.

  Specifically, since the control of the release actuator is invalidated, the door in the fully open state or the fully closed state does not close or open at an unexpected speed. As a result, the danger associated with opening and closing the door can be suppressed.

  In addition, when the power shut-off state is detected, the door position information is invalidated, so that erroneous door position information can be prevented from remaining. Therefore, the door is not controlled to open / close based on the wrong door position information even when the power cut-off state shifts to the power transmission state (when returning). As a result, the danger associated with opening and closing the door can be suppressed.

When the open side wire 22 is unwound while winding, the slide door 1 shifts from the open state shown in FIG. 4-2 to the closed state shown in FIG. 4-1.

  A sensor disk 30 is fixed to the outer end of the vehicle shaft of the wheel shaft 17 penetrating the housing 11. The sensor disk 30 is alternately magnetized with N and S poles, and the wheel shaft 17 is detected by a rotation detection sensor 32 made of a Hall element or an AMR element disposed on a sensor cover 31 covering the sensor disk 30. The rotation signal can be output as a pulse. Note that when the wheel connector disk 16 and the drum connector disk 18 are in a power transmission state, the wheel shaft 17 and the drum 13 rotate together, so that the rotation signal of the wheel shaft 17 is regarded as the rotation signal of the drum 13. It is possible.

  As shown in FIG. 3, an operation handle 34 is fixed to the end of the drum shaft 19 on the vehicle interior side via a locking piece 33, and the drum shaft 19 and the operation handle 34 can be rotated together. . When the operation handle 34 is rotated in a predetermined direction, the drum shaft 19 moves from the outside of the vehicle compartment to the inside of the vehicle compartment. Then, as shown in FIG. 3-2, the drum connector disk 18 moves to the vehicle interior side against the urging force of the compression coil spring 20, and the drum connector disk 18 is separated from the wheel connector disk 16. When the connector pin 16B fixed to the wheel connector disk 16 is detached from the through hole 18A formed in the drum connector disk 18, the drum 13 that rotates together with the drum connector disk 18 becomes rotatable (power cut-off state). ). Therefore, the slide door 1 can be manually opened and closed.

  The housing 11 is provided with a power cut-off state detection switch 35. In the power cut-off state detection switch 35, the connector pin 16B fixed to the wheel connector disk 16 is detached from the through hole 18A formed in the drum connector disk 18, and the power transmission from the wheel connector disk 16 to the drum connector disk 18 is cut off. The power transmission state is detected when the operation handle 34 presses the power cut-off state detection switch 35, and the power cut-off state is detected when the operation handle 34 is separated from the power cut-off state detection switch 35. To do.

  Next, the door opening / closing control apparatus will be described with reference to FIG. FIG. 5 is a block diagram showing a door opening / closing control apparatus according to an embodiment of the present invention. As shown in FIG. 5, the door opening / closing control device 40 is connected to a driver seat switch 41 provided in the driver's seat, a handle switch linked to a door handle (outside handle OH, inside handle IH) and a wireless remote control key 42. The door opening / closing operation can be input from any of these.

  The door opening / closing control device 40 is connected to the release actuator 51 of the remote controller 50, the motor 12, the rotation detection sensor 32, and the power shut-off state detection switch 35 of the door opening / closing device 10, and the remote controller 50 and the door opening / closing device 10 are connected. It can be controlled.

  Further, the door opening / closing control device 40 can acquire door position information by adding or subtracting the rotation signal (pulse signal) output from the rotation detection sensor 32 of the door opening / closing device 10. Therefore, the door opening / closing control device 40 can control the motor 12 of the door opening / closing device 10 according to the speed information associated with the door position information.

  Accordingly, when the door opening operation is input when the sliding door 1 is in the closed state, the door opening / closing control device 40 causes the release actuator 51 to operate the remote controller 50 so that the latch device 6 and the striker 7 are engaged. To release. When the meshing state of the latch device 6 and the striker 7 is released, the slide door 1 shifts from the closed state to the openable state. Thereafter, the door opening / closing control device 40 drives the motor 12 of the door opening / closing device 10 to open the slide door 1. At this time, the door opening / closing control device 40 adds the pulse signal output from the rotation detection sensor 32 to acquire the door position, and drives and controls the motor 12 at a speed suitable for the door position. Then, when the sliding door 1 shifts to the open state, the door opening / closing control device 40 stops the motor 12 of the door opening / closing device 10. At this time, since the fully open latch device 8 and the fully open striker 9 are engaged, the slide door 1 is maintained in the open state.

  On the other hand, when the door closing operation is input when the slide door 1 is in the open state, the door opening / closing control device 40 causes the release actuator 51 to operate the remote controller 50, so that the fully open latch device 8 and the fully open striker 9 Release the meshing state. When the meshing state of the fully open latch device 8 and the fully open striker 9 is released, the slide door 1 shifts from the open state to the closeable state. Thereafter, the door opening / closing control device 40 drives the motor 12 of the door opening / closing device 10 to move the slide door 1 closed. At this time, the door opening / closing control device 40 subtracts the pulse signal output from the rotation detection sensor 32 to acquire the door position, and drives and controls the motor 12 at a speed suitable for the door position. When the sliding door 1 shifts to the closed state, the door opening / closing control device 40 stops the motor 12 of the door opening / closing device 10. At this time, since the latch device 6 and the striker 7 mesh with each other, the sliding door 1 is maintained in the closed state.

  Further, the door opening / closing control device 40 invalidates the control of the latch device 6, the fully open latch device 8, and the door opening / closing device 10 when the power cutoff state detection switch 35 of the door opening / closing device 10 detects the power cutoff state. That is, when the power cut-off state detection switch 35 of the door opening / closing device 10 detects the power cut-off state, the release actuator 51 of the remote controller 50 does not operate and the acquired door position information is invalidated. In addition, by manually operating the outside handle OH or the inside handle IH, the remote controller 50 can release the engagement state between the latch device 6 and the striker 7 and the engagement state between the fully open latch device 8 and the fully open striker 9.

  According to the door opening / closing control device 40 according to the embodiment of the present invention, the opening / closing operation of the slide door 1 is invalidated when the power shut-off state detection switch 35 detects the power shut-off state. Even if input, the slide door 1 does not operate, and the danger associated with opening and closing the slide door 1 can be suppressed.

  Specifically, since the control of the release actuator 51 of the remote controller 50 is invalidated, the slide door 1 in the fully open state or the fully closed state does not close or open at an unexpected speed due to its own weight or the like. . As a result, the danger associated with opening and closing the slide door 1 can be suppressed.

  Further, when the power cut-off state detection switch 35 detects the power cut-off state, the door position information is invalidated, so that erroneous door position information can be prevented from remaining. Therefore, the sliding door 1 is not controlled to be opened or closed based on erroneous door position information even when the power cut-off state shifts to the power transmission state (when returning). As a result, the danger associated with opening and closing the slide door 1 can be suppressed.

  As described above, the door opening and closing control device according to the present invention is useful for a door opening and closing control device that controls opening and closing of a door that closes an opening formed in a vehicle, and in particular, door opening and closing control that controls opening and closing of a sliding door. Suitable for equipment.
