Further, as shown in FIG. 1, the door lock device 60 has a half-latch switch 68 and a full-latch switch 69 for detecting the position of the latch 61. As shown in FIG.

As shown in FIG. 2, the latch 61 includes a first engaging portion 611, a second engaging portion 612, a third engaging portion 613, and a fourth engaging portion 614 which are arranged side by side in the rotation direction of the latch 61. have The first engaging portion 611 , the second engaging portion 612 and the third engaging portion 613 extend in a direction intersecting the axis of the latch support shaft 63 . An engaging recess 615 is formed between the first engaging portion 611 and the second engaging portion 612 in the latch 61 . The latch 61 is biased clockwise in FIG. 2 by a latch biasing spring 65 . At this time, the latch 61 is arranged at the "unlatch position" shown in FIG. 2 by the fourth engaging portion 614 coming into contact with a latch stopper (not shown).

The pole 62 extends in a direction intersecting the axis of the pole support shaft 64 . The pole 62 is connected with a lift lever 67 via a pole support shaft 64 . Also, the pole 62 is biased counterclockwise in FIG. 2 by a pole biasing spring 66 . As shown in FIG. 2, the pole 62 contacts the second engaging portion 612 of the latch 61 when the latch 61 is in the unlatched position.

Next, operation of the door lock device 60 will be described.
When the back door 30 is at the open position, the latch 61 is at the unlatched position and the pole 62 contacts the second engaging portion 612 of the latch 61, as shown in FIG. Further, the opening of the engagement recess 615 of the latch 61 faces the striker 22 with respect to the rotation locus of the back door 30 .

Subsequently, when the back door 30 is closed to near the closed position, the striker 22 enters the engaging recess 615 of the latch 61 . Then, the striker 22 pushes the inner surface of the engagement recess 615, and the latch 61 rotates in the first rotation direction R11 while elastically deforming the latch biasing spring 65. As shown in FIG. Then, the pole 62 is engaged with the second engaging portion 612 of the latch 61, and the turning of the latch 61 in the second turning direction R12 is restricted. In the following description, the position of the latch 61 when the pawl 62 engages the second engaging portion 612 of the latch 61 is set to the "half-latch position" so that the latch 61 cannot rotate in the second rotation direction R12. ”. When the latch 61 is positioned at the half-latched position, the back door 30 is a so-called half-door.

When the back door 30 is closed to the closed position, the striker 22 further enters the engagement recess 615 of the latch 61 as shown in FIG. Then, the striker 22 pushes the inner surface of the engagement recess 615, and the latch 61 is further rotated in the first rotation direction R11 while causing the latch biasing spring 65 to elastically deform. Then, the pole 62 is engaged with the first engaging portion 611 of the latch 61, and the pivoting of the latch 61 in the second pivoting direction R12 is restricted. In the following description, the position of the latch 61 when the pole 62 engages the first engaging portion 611 of the latch 61 is defined as the "full latch position" so that the latch 61 cannot rotate in the second rotation direction R12. It says.

On the other hand, as shown in FIG. 4, when the pole 62 rotates away from the first engaging portion 611 when the latch 61 is in the fully latched position, the latch 61 restores the latch biasing spring 65. It is set to the second rotation direction R12 by force. That is, when the latch 61 rotates from the fully latched position toward the unlatched position, the striker 22 is no longer restrained by the engaging recess 615 of the latch 61 .

Similarly, when the pawl 62 rotates away from the second engaging portion 612 when the latch 61 is at the half-latched position, the latch 61 rotates in the second rotation direction due to the restoring force of the latch biasing spring 65 . Rotate to R12. That is, when the latch 61 rotates from the half-latched position toward the unlatched position, the striker 22 is no longer restrained by the engaging recess 615 of the latch 61 .

In the following description, the rotation of the latch 61 from the fully latched position or the half latched position toward the unlatched position is also referred to as "unlatch operation".
A half-latch switch 68 detects whether the latch 61 is in the half-latch position. A full latch switch 69 detects whether or not the latch 61 is in the full latch position.

Next, the door lock driving section 70 will be described.
As shown in FIG. 3, the door lock drive unit 70 includes a bracket 71 fixed to the back door 30, a pinion 72 rotatably supported by the bracket 71, a motor 73 for driving the pinion 72, and the pinion 72. and an active lever 74 driven to. The door lock drive unit 70 also has a passive lever 75 driven by the active lever 74 , a bell crank 76 driven by the active lever 74 , and an open lever 77 driven by the bell crank 76 .

The bracket 71 can rotate a first support shaft 781 that rotatably supports the active lever 74 and the passive lever 75, a second support shaft 782 that rotatably supports the bell crank 76, and the open lever 77. and a third support shaft 783 that supports the . The first support shaft 781 , the second support shaft 782 and the third support shaft 783 extend in a direction that intersects the rotation axis of the latch 61 .

The active lever 74 has a gear 741 meshing with the pinion 72 and an active lever pin 742 extending along the axis of the first support shaft 781 . The active lever 74 is placed in the "initial position" shown in FIG. 3 when the door lock device 60 does not need to be driven.

The passive lever 75 is rotatably supported by the first support shaft 781 independently of the active lever 74 . The passive lever 75 has a distal end 751 extending toward the latch 61 and a proximal end 752 positioned within the range of motion of the active lever pin 742 . Passive lever 75 is biased counterclockwise in FIG. That is, the passive lever 75 is urged so that the tip portion 751 moves away from the latch 61 .

The bellcrank 76 has a first end 761 extending toward the open lever 77 and a second end 762 positioned within the range of motion of the active lever pin 742 . The bellcrank 76 is biased clockwise in FIG. That is, the bellcrank 76 is biased such that the first end 761 moves away from the active lever 74 .

The open lever 77 has a first end 771 extending toward the lift lever 67, a second end 772 located within the range of motion of the first end 761 of the bellcrank 76, and a third end 773 extending between the first end 771 and the second end 771. It extends in a different direction than end 772 . The open lever 77 is biased counterclockwise in FIG. That is, the open lever 77 is biased so that the first end 771 moves away from the lift lever 67 .

Next, the action of the door lock driving section 70 will be described.
The passive lever 75 rotates the latch 61 to the full latch position by transmitting the power of the active lever 74 rotating in the first operating direction R21 to the latch 61 when the latch 61 is positioned at the half latch position.

Specifically, as shown in FIG. 3 , when the active lever 74 rotates in the first actuation direction R<b>21 , the base end 752 of the passive lever 75 is pushed by the active lever pin 742 of the active lever 74 . Subsequently, the passive lever 75 rotates so that the distal end portion 751 of the passive lever 75 approaches the third engaging portion 613 of the latch 61, as indicated by the dashed line arrow in FIG. Then, the distal end portion 751 of the passive lever 75 pushes the third engaging portion 613 of the latch 61 positioned at the half latch position, and the latch 61 rotates toward the full latch position. The active lever 74 moves back toward the initial position after the passive lever 75 has been rotated the amount necessary to rotate the latch 61 to the fully latched position. At this time, the passive lever 75 returns to the position shown in FIG. 3 because the power is no longer transmitted from the active lever 74 .

On the other hand, the bell crank 76 and the open lever 77 transmit the power of the active lever 74 rotating in the second operating direction R22 to the pole 62 when the latch 61 is in the fully latched position or the half latched position. 61 is rotated to the unlatched position.

Specifically, as shown in FIG. 5, when the active lever 74 rotates in the second actuation direction R22, the second end 762 of the bellcrank 76 is pushed against the active lever pin 742 of the active lever 74. As shown in FIG. Subsequently, the bellcrank 76 rotates as indicated by the dashed-dotted arrow in FIG. Further, the open lever 77 rotates as indicated by the dashed line in FIG. 5 , and the first end 771 of the open lever 77 pushes the lift lever 67 . As a result, the pole 62 rotates together with the lift lever 67 .

Here, when the latch 61 is positioned at the full-latch position, the pole 62 rotates so as not to engage with the first engaging portion 611 of the latch 61, and when the latch 61 is positioned at the half-latch position, , the pole 62 rotates so as not to engage with the second engaging portion 612 of the latch 61 . As a result, the latch 61 becomes rotatable in the second rotation direction R<b>12 , and the latch 61 rotates toward the unlatched position by the restoring force of the latch biasing spring 65 . That is, the latch 61 is unlatched.

The active lever 74 moves back toward the initial position when the lift lever 67 is pivoted the amount necessary to disengage the pole 62 from the latch 61 . At this time, the bellcrank 76 and the open lever 77 return to the positions shown in FIG. 4 because the power is no longer transmitted from the active lever 74 .

As shown in FIG. 1, the door control device 90 receives a signal input from the operation switch 31, a signal input from the portable device 100 such as an electronic key, a signal input from the close switch 32, and an input from the half-latch switch 68. The door driving section 50 and the door lock driving section 70 are controlled based on the signal input from the full latch switch 69 and the signal input from the full latch switch 69 .

Specifically, the door control device 90 determines whether or not there is a request for opening and closing the back door 30 from the user based on a signal input from the operation switch 31 and a signal input from the portable device 100 . Further, the door control device 90 determines whether or not the back door 30 is positioned at the closed position based on the signal input from the close switch 32 . Furthermore, the door control device 90 determines the position of the latch 61 based on the signal input from the half-latch switch 68 and the signal input from the full-latch switch 69 .

When the door control device 90 receives an opening operation request for opening the back door 30 from the operation switch 31 and the portable device 100 while the back door 30 is in the closed position, the door lock drive is performed. Portion 70 rotates latch 61 to the unlatched position. Subsequently, after the latch 61 rotates to the unlatched position, the door control device 90 causes the door drive section 50 to open the back door 30 toward the open position. Here, the open position may be a position determined based on the specifications of the back door 30, or may be a memory position arbitrarily set by the user.

On the other hand, when the door control device 90 receives a closing operation request for closing the back door 30 from the operation switch 31 and the portable device 100 while the back door 30 is in the open position, the door driving unit 50 actuates the back door 30 to the closed position. Subsequently, after the latch 61 is rotated to the half-latched position as the back door 30 is closed, the door control device 90 causes the door lock driving section 70 to rotate the latch 61 from the half-latched position to the fully latched position.

By the way, when the back door 30 is positioned at the open position, the door lock mechanism of the back door 30 is placed within reach of the user. Therefore, if the user performs a special operation such as hooking a foreign object such as a rope on the latch 61, the latch 61 is moved to the half-latched position or the full-latched position even though the back door 30 is not in the closed position. It may rotate. In this case, when the back door 30 is closed, the latch 61 positioned at the half-latched position or the full-latched position, that is, the latch 61 whose engaging recess 615 does not face the striker 22 may come into contact with the striker 22 . Alternatively, there is a risk that a foreign object caught on the latch 61 may be caught between the striker 22 and the striker 22 .

Therefore, the door control device 90 of the present embodiment, when a request for closing the back door 30 is input in a situation where the back door 30 is in the open position and the latch 61 is in the unlatched position, the back door 30 is closed. 30 is allowed to close.

On the other hand, the door control device 90 closes the back door 30 when a request for closing the back door 30 is input in a situation where the back door 30 is in the open position and the latch 61 is not in the unlatched position. limit. The state in which the latch 61 is not in the unlatched position includes both the state in which the latch 61 is in the fully latched position and the state in which the latch 61 is in the half latched position.

Further, when the back door 30 is in the open position and the latch 61 is not in the unlatched position, the door control device 90 instructs the user to close the back door 30 . The notification unit 80 is caused to issue a warning to the effect that a foreign object is attached to the object 61.例文帳に追加Note that the notification unit 80 may notify the warning by sound, light, vibration, or the like. Furthermore, under the same circumstances, when a request for closing the back door 30 is input, the door control device 90 unlatches the latch 61 .

Next, a processing routine executed by the door control device 90 when the user inputs a request to close the back door 30 will be described with reference to the flowchart shown in FIG.
As shown in FIG. 6 , when the user inputs a request to close the back door 30 , the door control device 90 adjusts the back door 30 to the open position based on the signal input from the close switch 32 . It is determined whether or not there is (step S11). If the back door 30 is located at the closed position (step S11: NO), the door control device 90 once terminates this process.

On the other hand, if the back door 30 is at the open position (step S11: YES), the door control device 90 causes the latch 61 to move to the unlatched position based on the signals input from the half-latch switch 68 and the full-latch switch 69. (step S12). When the latch 61 is located at the unlatched position (step S12: YES), the door control device 90 closes the back door 30 (step S13). After that, the door control device 90 once terminates this process.

On the other hand, when the latch 61 is positioned at the half latch position or the full latch position (step S12: NO), that is, when the user is performing a special operation on the door lock device 60, the door control device 90 The notification unit 80 is caused to notify the user that a foreign object is attached to the latch 61 (step S14). After that, the door control device 90 unlatches the latch 61 to the unlatched position (step S15), and terminates this processing.

The action and effect of this embodiment will be described.
(1) The door control device 90 restricts the closing operation of the back door 30 when the closing operation request is input under the condition that the back door 30 is in the open position and the latch 61 is not in the unlatched position. . Therefore, the door control device 90 can prevent the latch 61 positioned at the full-latched position or the half-latched position from contacting the striker 22 . In addition, the door control device 90 can prevent foreign matter caught on the latch 61 from contacting the striker 22 in order to position the latch 61 at the full-latch position or the half-latch position. Further, the door control device 90 can prevent the back door 30 to be closed by the user who is trying to remove the foreign matter from the latch 61 by operating the operation switch 31 or the like from contacting the user. In this way, the door control device 90 can perform a special operation such as rotating the latch 61 to the full-latched position or the half-latched position while the back door 30 is in the open position. The closing operation of the door 30 can be appropriately controlled.

(2) A situation in which the back door 30 is in the open position and the latch 61 is not in the unlatched position is not a favorable situation for the vehicle 10 . In this regard, the door control device 90 causes the notification unit 80 to issue a warning when a closing operation request is input under the above circumstances. Therefore, the door control device 90 can warn the user that a special operation such as catching a foreign object on the latch 61 has been performed. That is, the door control device 90 can prevent a user who once performed a special operation such as hooking a foreign object on the latch 61 from performing the same special operation again.

(3) The door control device 90 receives an initial closing operation request based on the user's operation of the operation switch 31 or the like in a situation where the back door 30 is in the open position and the latch 61 is not in the unlatched position. If so, the latch 61 is unlatched. In this case, the back door 30 is in the open position and the latch 61 is in the unlatched position. Therefore, the door control device 90 closes the back door 30 when a closing request based on the user's operation of the operation switch 31 or the like is input again. In this way, the door control device 90 can prevent a situation in which the back door 30 does not close, thereby preventing a decrease in convenience for the user.

This embodiment can be implemented with the following modifications. This embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.
- As described above, when the back door 30 is in the open position, the user's special operation of displacing the latch 61 to the fully latched position is an unexpected and undesirable operation for the vehicle 10 . Therefore, when the back door 30 is at the open position and the latch 61 is at the full latch position, the door control device 90 unlatches the latch 61 when a closing operation request is input. The required time may be longer. In this case, the door control device 90 can prompt the user not to perform a special operation by making the user feel inconvenient.

When the back door 30 is in the open position and the latch 61 is in the fully latched position, the door control device 90 does not unlatch the latch 61 when a closing operation request is input, and issues a warning. may be notified only.

When the back door 30 is in the open position and the latch 61 is in the full latch position, the door control device 90 closes the latch 61 without issuing a warning when a closing operation request is input. Only unlatch operation may be performed.

- The door control device 90 may be applied to control the opening/closing operation of a sliding door and a swing door, which are examples of doors.
- The vehicle body 20 may have the door lock device 60 and the back door 30 may have the striker 22 .

- The door drive unit 50 may be an actuator configured to be extendable using a so-called feed screw mechanism.
