Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
In FIG. 1, reference numeral 1 denotes a minivan or wagon-type automobile body, 2 a slide door supported on the side of the vehicle body 1 so as to be openable and closable in the front-rear direction, and 3 a rear end portion in the slide door 2. The door latch 4 is an electric closer mechanism connected to the door latch 3, the electric release actuator 5 is connected to the door latch 3, and the door electric motor 6 is used to open and close the slide door 2 by the power of the motor. Opening and closing mechanism.

  The closer motor 41 of the closer mechanism 4, the release motor 51 of the release actuator 5, and the door opening / closing motor 61 of the door electric opening / closing mechanism 6 are controlled by a controller 7 provided at an appropriate position of the vehicle body 1 as described later.

  The present invention is not limited to this embodiment, and can be applied to, for example, a swing-type side door or a back door that can be opened and closed in the vertical direction instead of the slide door 2.

  The vehicle body 1 and the slide door 2 are always electrically connected to each other with an extendable electric wire, and the electric power of the in-vehicle battery 8 provided on the vehicle body 1 side is supplied to the slide door 2 side regardless of the position of the slide door 2. In addition, the detection signal of each switch provided on the slide door 2 side can be transmitted to the controller 7.

  As shown in FIG. 2, the door latch 3 is engaged with a striker (not shown) fixed to the vehicle body 1 side to hold the slide door 2 in the fully closed position, and the latch mechanism 31 and the striker. A release mechanism 32 that releases the engagement and enables the sliding door 2 to open is provided. The release mechanism 32 receives the operations of the door handle 21 and the release actuator 5 that are provided on the slide door 2 and are operated when the slide door 2 is opened.

  The latch mechanism 31 has an open state in which it is detached from the striker, a half latch state (corresponding to a half door position of the slide door 2) that is barely engaged with the striker when the slide door 2 is closed, and a full latch that is completely engaged with the striker. It can be operated in a state (corresponding to a fully closed position of the slide door 2). The door latch 3 is provided with a half latch detection switch 9 capable of detecting the half latch state of the latch mechanism 31 and a full latch detection switch 10 capable of detecting the full latch state.

  The closer mechanism 4 has a closer motor 41 and an output lever (not shown) that decelerates and outputs the rotation of the closer motor 41, and the output lever is connected to the latch mechanism 31 via a power cutting mechanism 33 described later of the door latch 3. Thus, when the half-latch detection switch 9 detects the half-latch state of the latch mechanism 31 during the closing movement of the slide door 2, the closer motor 41 is driven in the closing direction to drive the output lever and the power cutting mechanism 33. To the latch mechanism 31, and the latch mechanism 31 is operated from the half latch state to the full latch state to move the slide door 2 from the half door position to the fully closed position. When the full latch detection switch 10 detects the full latch state of the latch mechanism 31, the closer motor 41 and the output lever are reversed, and the closer mechanism 4 returns to the initial state before the operation.

  The release actuator 5 has a release motor 51 and an output lever (not shown) that decelerates and outputs the rotation of the release motor 51. The output lever is connected to the release mechanism 32 of the door latch 3, and is connected to a wireless operation switch or in the vehicle. When the predetermined operation switch 11 provided is opened, the release motor 51 is driven and the drive is transmitted to the release mechanism 32 via the output lever, thereby releasing the release mechanism 32 and the latch mechanism 31. The engagement with the striker is released, and the sliding door 2 can be opened.

  The power cutting mechanism 33 normally transmits power between the output lever of the closer mechanism 4 and the latch mechanism 31 so that the operation of the output lever due to rotation of the closer motor 41 in the closing direction in the closer mechanism 4 can be transmitted to the latch mechanism 31. Although the path is connected, when the release mechanism 32 is released by the opening operation of the door handle 21 or the release actuator 5, the power transmission path between the output lever of the closer mechanism 4 and the latch mechanism 31 is cut off. The operation of the output lever of the closer mechanism 4 is made impossible to transmit to the latch mechanism 31. Thereby, even when the latch mechanism 31 is operating from the half latch state to the full latch state in accordance with the closing operation of the closer mechanism 4, the latch mechanism 31 is brought into the disconnected state by setting the power disconnection mechanism 33 to the disconnected state. The return operation to the open state becomes free.

  The door electric opening / closing mechanism 6 is disposed on the side of the vehicle body 1, and is a door opening / closing motor 61 that can rotate forward and backward, and a rotating drum that can be rotated via a speed reducer (not shown) by the rotation of the door opening / closing motor 61. 62, an electromagnetic clutch 63 capable of intermittently connecting a power transmission path between the door opening / closing motor 61 and the rotary drum 62, and wound around the rotary drum 62 so as to be able to be wound and fed out, and connected to the rear end portion of the slide door 2. The power transmission cable 64 is provided.

  When the electromagnetic clutch 63 is in a state where the power transmission path is disconnected, the slide door 2 can be manually opened and closed with little force without receiving resistance to reverse the door opening / closing motor 61.

  The rotary drum 62 that rotates in synchronization with the opening and closing movement of the slide door 2 is provided with a movement sensor 65 that detects the rotation angle of the rotary drum 62. The movement sensor 65 is constituted by a rotary encoder capable of generating a pulse signal corresponding to the rotation angle of the rotary drum 62 (corresponding to the movement amount of the slide door 2) and the rotation direction (corresponding to the movement direction of the slide door 2).

  As shown in FIG. 3, the controller 7 includes a control processing unit 71 mainly composed of a microcomputer, a switching relay circuit 72, a closer relay circuit 73, an electromagnetic clutch relay circuit 74 and a door controlled by the control processing unit 71. An open / close motor relay circuit 75 is provided. The input port of the controller 7 includes a half latch detection switch 9, a full latch detection switch 10, an operation switch 11, a door switch 12 that detects the opening / closing of the slide door 2, a release detection switch 13 that detects the release operation of the release mechanism 32, and a slide. Each signal output from the pinching detection sensor 14 configured by a pressure-sensitive sensor that detects that an object has been pinched between the door 2 and the vehicle body 1 is input, and the closer motor 41 and the release motor are also input to the output port. 51, the door opening / closing motor 61 and the electromagnetic clutch 63 are electrically connected.

Next, control performed by the controller 7 will be described.
(When the operation switch 11 is opened when the slide door 2 is in the fully closed position)
When an opening operation signal for the operation switch 11 is input to the controller 7, the control processing unit 71 sends an open control command to the switching relay circuit 72. As a result, the movable contact 721 of the switching relay circuit 72 changes from the state in which the power of the in-vehicle battery 8 can be supplied to the energization path on the closer relay circuit 73 side (the state indicated by the solid line in FIG. 3) to the energization path on the release motor 51 side. The state is switched to a supplyable state (a state indicated by a two-dot chain line in FIG. 3), and the electric power of the in-vehicle battery 8 can be supplied to the release motor 51 via the switching relay circuit 72.

  The release actuator 5 releases the release mechanism 32 via the output lever with the release drive of the release motor 51 to release the engagement between the latch mechanism 31 of the door latch 3 and the striker. The controller 7 drives and controls the electromagnetic clutch relay circuit 74 and the door opening / closing motor relay circuit 75 when at least the door switch 12 detects the opening of the slide door 2. As a result, the electromagnetic clutch 63 is in the connected state, and the door opening / closing motor 61 is driven in the opening direction, and the sliding door 2 can be moved in the opening direction by the driving.

(When the operation switch 11 is closed when the slide door 2 is in the fully open position)
When a closing operation signal for the operation switch 11 is input to the controller 7, the control processing unit 71 drives and controls the electromagnetic clutch relay circuit 74 and the door opening / closing motor relay circuit 75. Thereby, the electromagnetic clutch 63 will be in a connection state and the door opening / closing motor 61 will rotate in a closing direction. As a result, the rotation of the door opening / closing motor 61 in the closing direction is transmitted to the sliding door 2 via the electromagnetic clutch 63, the rotating drum 62, and the cable 64, and the sliding door 2 moves in the closing direction.

  When the slide door 2 reaches the half door position and the half latch detection switch 9 detects the half latch state of the latch mechanism 31, the half latch signal is input to the controller 7. The control processing unit 71 controls both the door opening / closing motor relay circuit 75 and the electromagnetic clutch relay circuit 74 to be turned off, and closes the closer relay circuit 73 so that the closer motor 41 is driven in the closing direction.

  By the above control, the door electric opening / closing mechanism 6 is stopped and the closer mechanism 4 is closed. This closing operation is transmitted to the latch mechanism 31 via the power cutting mechanism 33. The latch mechanism 31 operates from the half latch state to the full latch state, and moves the slide door 2 from the half door position to the fully closed position. When the full latch detection switch 10 detects the full latch state of the latch mechanism 31, the control processing unit 71 reversely controls the closer motor relay circuit 73 based on the full latch signal to invert the closer motor 41. Thereby, the closer mechanism 4 returns to the initial state before the operation and stops.

(During closing operation of the closer mechanism 4, when the pinching detection sensor 14 detects pinching of an object or when the operation switch 11 is opened)
As shown in FIG. 4, when the sliding door 2 is closed, the half latch signal (ON) from the half latch detection switch 9 is input to the controller 7 at the half door position A, and the control processing unit 71 closes the closer motor 41. During the drive control in the direction, when the pinch detection sensor 14 detects the pinching of the object at the position C, or when the operation switch 11 is opened before the pinch detection sensor 14 detects the pinch of the object, A sandwiching signal or an opening operation signal is input to the controller 7.

  The control processing unit 71 of the controller 7 first sends a switching control command to the switching relay circuit 72 based on the pinching signal or the opening operation signal. As a result, the movable contact 721 of the switching relay circuit 72 changes from the state in which the power of the in-vehicle battery 8 can be supplied to the energization path on the closer relay circuit 73 side (the state indicated by the solid line in FIG. 3) to the energization path on the release motor 51 side. The state is switched to a supplyable state (a state indicated by a two-dot chain line in FIG. 3), and the electric power of the in-vehicle battery 8 can be supplied to the release motor 51 via the switching relay circuit 72. As a result, when the power supply to the closer motor 41 is interrupted, the power is supplied to the release motor 51 almost simultaneously, and the release actuator 5 starts the release operation to release the release mechanism 32 and the power cutting mechanism. 33 is in a disconnected state. Thereby, the power transmission path between the latch mechanism 31 and the closer mechanism 4 is cut, and the latch mechanism 31 can be operated to the open state.

  Then, based on the release operation of the release mechanism 32, after the release detection switch 13 detects (ON) the release operation of the release mechanism 32, at least when the door switch 12 detects the opening of the slide door 2 at the position B, the control process The unit 71 controls the opening of the door opening / closing motor 61 by controlling the electromagnetic clutch relay circuit 74 to be turned on and opening the door opening / closing motor relay circuit 75. As a result, the slide door 2 immediately moves in the opening direction by the operation of the door electric opening / closing mechanism 6.

  Further, almost simultaneously with the opening drive control of the door opening / closing motor 61, the movable contact 721 of the switching relay circuit 72 is in a state in which the electric power of the in-vehicle battery 8 can be supplied to the energization path on the release motor 51 side (in FIG. The state is switched from the state shown in FIG. 3 to a state in which it can be supplied to the energization path on the closer relay circuit 73 side (the state shown by the solid line in FIG. 3), and the closer relay circuit 73 is controlled in the reverse direction. As a result, power supply to the release motor 51 is interrupted, the closer motor 41 is reversed, and the closer mechanism 4 returns to the initial state before operation.

  As described above, when the pinch detection sensor 14 detects the pinching of an object during the closing operation of the closer mechanism 4 or when the operation switch 11 is opened, the closing drive of the closer motor 41 is interrupted to open the door opening / closing motor. Since 61 is reversed in the opening direction, the slide door 2 can be immediately reversed in the opening direction without waiting for the closer mechanism 4 to return to the initial state as in the prior art.

(When the door handle 21 is opened during the closing operation of the closer mechanism 4)
As shown in FIG. 5, the door handle 21 is moved at the position D while the closer motor 41 is driven in the closing direction based on the half latch signal of the half latch detection switch 9 at the half door position A of the slide door 2. When the opening mechanism is opened, the release mechanism 32 releases the power and also turns the power cutting mechanism 33 into the cutting state, thereby enabling the latch mechanism 31 to be opened. Further, when the release detection switch 13 detects the release operation of the release mechanism 31 and this detection signal is input to the controller 7, the control processing unit 71 controls the closing of the closer relay circuit 73 to supply power to the closer motor 41. Interrupt supply.

  At position B, when the open signal of the half latch detection switch 9, the open signal of the full latch detection switch 10, and the door switch 12 detect the opening of the slide door 2, the control processing unit 71 performs the electromagnetic clutch relay circuit 74 and the door opening / closing. The relay circuit 75 is controlled to control the door opening / closing motor 61 to open. As a result, the slide door 2 immediately moves in the opening direction by the operation of the door electric opening / closing mechanism 6.

  At the same time as the opening / closing control of the door opening / closing motor 61, the closer relay circuit 73 is reversely controlled to reverse the closer motor 41, thereby returning the closer mechanism 4 to the initial state before the operation.

  Note that the reverse control of the closer motor 41 is not limited to the present embodiment. For example, the reversal activation of the closer motor 41 is delayed for a predetermined time from the activation of the door opening / closing motor 61 so that the reversal driving control of the closer motor 41 does not start simultaneously with the start of the opening / closing control of the door opening / closing motor 61. As a result, a rapid current consumption can be suppressed, a starting current for the door electric opening / closing mechanism 6 can be secured, and the slide door 2 can be controlled to a target speed at an early stage.

  As described above, even when the door handle 21 is opened during the closing operation of the closer mechanism 4, the closing operation of the closing motor 41 is interrupted and the door opening / closing motor 61 is reversed in the opening direction. The slide door 2 can be immediately reversed in the opening direction without waiting for the closer mechanism 4 to return to the initial state, and the object can be prevented from being caught.
