FIG. 1 is a flowchart illustrating the opening / closing operation of the back door of the vehicle back door opening / closing apparatus 100 according to the present embodiment.

  As shown in FIG. 1, in step S <b> 101, the vehicle back door opening / closing device 100 detects, by the operation start detection means 11, operation start information Im input to the vehicle by a driver or the like to open / close the vehicle back door. . Here, the operation start detection means 11 can detect the operation start information Im by detecting that the opener SW is pressed, for example.

  When the vehicle back door opening / closing device 100 detects the operation start information Im, the process proceeds to step S102. When the vehicle back door opening / closing device 100 does not detect the operation start information Im, the vehicle back door opening / closing device 100 can repeat the same operation until the operation start information Im is detected.

  Next, in step S <b> 102, the vehicle back door opening / closing device 100 detects the opening / closing state information Ids as the back door information Id by the opening / closing state detection means 12. Here, the vehicle back door opening / closing device 100 can acquire the door state by detecting the opening / closing state information Ids by the opening / closing state detecting means 12.

  The vehicle back door opening / closing device 100 detects the opening / closing state information Ids, and then proceeds to step S103.

  In step S103, the vehicle back door opening / closing device 100 detects the opening / closing operation information Idm as the back door information Id by the opening / closing operation detecting means 13. Here, the vehicle back door opening / closing device 100 can acquire other vehicle states by detecting the opening / closing operation information Idm by the opening / closing operation detecting means 13.

  After detecting the opening / closing operation information Idm, the vehicle back door opening / closing device 100 proceeds to step S104.

  In step S <b> 104, the vehicle back door opening / closing device 100 uses the state determination unit 21 to add back door information Id (opening / closing state information Ids and / or opening / closing operation information Idm detected by the opening / closing state detection unit 12 and the opening / closing operation detection unit 13). Based on this, it is determined whether the operation start information Im detected by the operation start detection means 11 is the back door opening information Imo or the closing information Imc. Here, the vehicle back door opening / closing device 100 estimates the scene by determining whether the state determination means 21 is the opening information Imo or the closing information Imc by a logical operation (the state where the back door is opened). And whether or not the back door is in a closed state.

  Specifically, the state determination unit 21 detects when the operation start detection unit 11 detects the operation start information Im when the open / close state information Ids is “a state where the back door is not fully closed” (for example, the opener SW is pressed). ), It can be determined that the operation start information Im is backdoor closing information Imc. Note that the above case is a case where the driver or the like closed the back door but did not close it completely (for example, because it is a half-door), so that the back door is closed again.

  Further, the state determination means 21 indicates that a half-door alarm or the like is issued when the opening / closing state information Ids is “a state where the back door is not fully closed” and the opening / closing operation information Idm is “the back door is locked (locked)”. In the case of “output state” (logical product), when the operation start detecting means 11 detects the operation start information Im, it can be determined that the operation start information Im is the back door closing information Imc. In the above case, the driver closes the back door, but when the driver notices that the driver is a half-door due to a half-door alarm or other output (sounds), it closes the back door again. Etc.

  Further, the state determination means 21 indicates that the opening / closing state information Ids is “a state where the back door is not fully closed” and the opening / closing operation information Idm is “a state where opening, closing and opening of the back door is operated at the driver's seat”. In the case (logical product), when the operation start detecting means 11 detects the operation start information Im, it can be determined that the operation start information Im is the back door closing information Imc. Further, the state determination means 21 is in a case where the opening / closing state information Ids is “a state where the back door is fully closed” and the opening / closing operation information Idm is “a state where the back door is opened and closed within a predetermined time”. Also in (logical product), when the operation start detection means 11 detects the operation start information Im, it can be determined that the operation start information Im is the back door closing information Imc. In the above case, the driver or the like closed the back door incompletely (half-door) or completely closed, but if the half-door is confirmed with an indicator on the driver's seat or the like, or the back door is closed again just in case. Such as the case.

  On the other hand, the state determination means 21 indicates that the opening / closing state information Ids is “a state where the back door is fully closed” and the opening / closing operation information Idm is “a state where the back door is not opened and closed within a predetermined time”. In the case (logical product), when the operation start detection means 11 detects the operation start information Im, it can be determined that the operation start information Im is the back door opening information Imo. Note that the above case refers to a case where the driver or the like opens the back door (so-called normal back door opening operation).

The vehicle back door opening and closing apparatus 100 can automatically move the back door in the opening direction for a certain time until the back door is completely opened. For this reason, the vehicle back door opening and closing device 100 can completely open the back door.

  Here, the fixed time can be a time corresponding to the type of vehicle, the type of door, the shape of the door, and the state of the vehicle. Further, the predetermined time can be set to a time determined in advance by experiment or numerical calculation. Furthermore, the fixed time may be 700 ms.

  Thereafter, the vehicle back door opening / closing device 100 proceeds to END in the drawing, and ends the operation of opening / closing the back door (operation of opening the back door).

  On the other hand, in step S107, the vehicle back door opening / closing device 100 moves the back door by the driving means 30 in order to close the back door again. Specifically, the drive unit 30 controls the drive of the door drive unit 31 (motor or the like) by the drive control unit 22 and uses the driving force of the door drive unit 31 to move the back door in the opening direction and the closing direction. can do. Here, the time for moving the back door in the opening direction is the time during which the operation start detecting means 11 detects the operation start information Im in step S108 described later (for example, the time when the opener SW is pressed). Can do.

  Thereafter, the vehicle back door opening / closing device 100 proceeds to step S108.

  Next, in step S108, the vehicle back door opening / closing device 100 is operated by the driving unit 30 in accordance with the time during which the operation start detecting unit 11 detects the operation start information Im (for example, the time when the opener SW is pressed). The back door can be moved. Specifically, the vehicle back door opening / closing device 100 can move the back door in the opening direction by the driving unit 30 when the operation start detecting unit 11 detects the operation start information Im (step S107). As a result, the vehicle back door opening / closing device 100 moves the back door in the closing direction by the driving means 30 when the operation start information Im cannot be detected (for example, when the press is released after the opener SW is pressed). can do.

  That is, the vehicle back door opening / closing device 100 moves the back door in the opening direction when the operation start information Im is detected in steps S107 and S108, and closes the back door when the operation start information Im is no longer detected. Can move in the direction. Thus, the vehicle back door opening / closing device 100 can automatically move the back door and reclose the back door when the driver or the like recloses the back door at an arbitrary timing. For this reason, when the back door is moved in the closing direction after moving the back door in the opening direction for a certain period of time (when reclosing), it may take time to reclose the back door. In the door opening and closing device 100, since the driver can reclose the back door at any timing (for example, the opener SW can be pressed and released at any timing), the time required to reclose the back door Can be shortened.

  Note that the vehicle back door opening / closing device 100 may move the back door in the opening direction and the closing direction at predetermined time intervals from when the operation start information Im is detected. Here, the predetermined time interval may be a time interval corresponding to the type of vehicle, the type of door and the shape of the door, and the state of the vehicle. Further, the predetermined time interval can be set to a time interval determined in advance by experiment or numerical calculation. Furthermore, the predetermined time interval may be 350 ms.

  Thereafter, the vehicle back door opening / closing device 100 fixes (locks) the position of the back door by the door latch means 32, and then proceeds to END in the drawing to end the operation of opening and closing the back door (operation of closing the back door). .

  As described above, in the vehicle back door opening / closing apparatus 100 according to the embodiment of the present invention, when the operation start information is input and the opening / closing operation of the back door is started, the operation start information is information on the opening operation or is closed. Since it is possible to determine whether the information is related to the correction operation, the back door opening / closing operation can be selected by selecting the back door opening operation and the closing operation. Further, the vehicle back door opening / closing device 100 moves the back door in the opening direction when the operation start information Im is detected, and moves the back door in the closing direction when the operation start information Im is no longer detected. Therefore, the back door can be reclosed at any timing preferred by the driver. That is, the operability of the opening / closing operation of the back door can be improved.
