  Inside such a slide door 4 is not provided an operation handle (inner handle) for door opening / closing as in the prior art, and instead, an operation panel 15 of the door control device 13 is provided. FIG. 3 is an explanatory view showing an installation state of the operation panel 15, and FIG. 4 is an explanatory view showing a configuration of the operation panel 15. As shown in FIG. The door control device 13 according to the present invention comprises a control unit (control unit) 16 disposed on the side of the vehicle body 2 and an operation panel (operation unit) 15 which is a user interface. The operation panel 15 is electrically connected to the control unit 16, and is installed on the vehicle front side of the slide door 4 as shown in FIG. The operation panel 15 is provided with a liquid crystal panel (display / operation unit) 17 as a display surface on which a user can perform a touch operation, and the liquid crystal panel 17 has functions that can be used according to the current situation of the vehicle. Is displayed. The operation panel 15 transmits the user's intention to the control unit 16 based on the user's touch operation on the liquid crystal panel 17, and the control unit 16 controls the operation of the slide door 4 based on this instruction.

  The operation panel 15 is rotatably attached to the slide door 4 with the hinge portion 18 as a center, and can be moved to the storage position P, the in-vehicle operation position Q, and the out-of-vehicle operation position R. The movement operation between the positions P to R is performed by a panel drive motor 19 disposed in the slide door 4. The panel drive motor (operation unit drive means) 19 is also driven and controlled by the control unit 16. A shock absorbing pad (impact shock absorbing portion) 21 formed of a flexible member is attached to the side of the liquid crystal panel 17 of the operation panel 15 so that collision protection of the user in the car and protection of the liquid crystal panel 17 are achieved. .

  The storage position P is used when the vehicle is kept in a garage or the like, during traveling, etc., and the operation panel 15 is housed in the door panel (liner) 22. The in-vehicle operation position Q is an arrangement that assumes an operation by a user in the vehicle, and the operation panel 15 protrudes into the vehicle compartment, and the liquid crystal panel 17 is disposed toward the user's in-vehicle seating position. The operation panel 15 is provided with a human sensor 23 for detecting the approach of a person, and when the operation panel 15 is at the storage position P, the control unit 16 senses it when the user approaches the hand, and the operation in the vehicle Move to position Q. The operation position R outside the vehicle is assumed to be an operation by the user outside the vehicle, and the operation panel 15 protrudes into the vehicle compartment as well as the operation position Q in the vehicle, but the liquid crystal panel 17 is easy to operate from the user outside the vehicle , Is disposed toward the front end side of the slide door 4.

  In the in-vehicle operation position Q and the out-of-vehicle operation position R, the user can manually open and close the slide door 4 by putting a hand on the operation panel 15. Therefore, although there is no handle for opening and closing the door in the vehicle 1, the manual operation of the slide door 4 is possible by the operation panel 15 at the in-vehicle operation position Q and the out-of-vehicle operation position R. The slide door 4 is provided with a latch release lever 24 below the operation panel 15 in order to mechanically release the latch of the slide door 4 regardless of the operation panel 15 when an abnormality occurs in the electrical system. ing. The latch release lever 24 is installed inside the door, usually covered by a cover, and in the event of an abnormality, the cover is removed and operated.

  FIG. 5 is an explanatory view showing a display appearing on the liquid crystal panel 17. A capacitive touch panel is used for the liquid crystal panel 17. Here, four functions of "OPEN", "CLOSE", "Return" and "Picture of a key (lock / unlock)" are buttons. Is displayed. Further, only text information can be displayed on the liquid crystal panel 17 as needed. When the panel display "OPEN" is touched, the slide door 4 operates in the opening direction (opening direction). In addition, when “CLOSE” is touched, the slide door 4 operates in the closing direction (closing direction). When "Return" is touched, a "Return mode" is performed in which the door is locked after the door is closed. In the operation panel 15, a plurality of operations can be integrated by one touch, so here, the “return mode” is set by aggregating operations (door closing and door lock) when leaving the vehicle when returning home. When the “picture of key” is touched, an electric door lock mechanism (not shown) for locking and unlocking the slide door 4 is activated to switch the locked state (locking and unlocking) of the slide door 4.

  Each display of the liquid crystal panel 17 is displayed only when the function can be used (when active). That is, “OPEN” appears (lights up) only when a door open condition is satisfied, such as “door fully closed, vehicle speed 0 or door open or closed”, for example. In other words, when the slide door 4 is fully open or the vehicle 1 is traveling, the display of "OPEN" does not appear, and the operation panel 15 can not be operated to open the door. Similarly, "CLOSE" appears only when the door closing condition is satisfied, such as "during full door opening or door opening / closing operation", and "return" is when the interlocking operation condition is satisfied, such as "full door opening / vehicle speed 0". Appears only. As described above, since the display is switched depending on the situation and an unnecessary display does not appear, an erroneous operation can be prevented, and the operation method can be easily understood even when another person's vehicle is taken.

  In addition, these displays on the liquid crystal panel 17 are appropriately adjusted to a brightness that is easy for the user to see by the illuminance sensor 25 provided on the operation panel 15, and are brightly displayed at night or while traveling in a tunnel. Then the display will be slightly reduced in illuminance. Therefore, the operating position can be recognized at a glance even in the dark, and since there is no brighter light than necessary, the convenience is high, and the design of the vehicle interior can be improved. In addition, when the indication of "return" is unclear to foreigners etc., it may be displayed as "CLOSE & LOCK".

  FIG. 6 is a block diagram showing a system configuration of the door control device 13. As described above, the door control device 13 is composed of the control unit 16 and the operation panel 15. As shown in FIG. 6, on the control unit 16 side, a CPU 31 for controlling the entire operation of the slide door 4, a RAM 32 for temporarily storing detection information (data), etc., control programs and various control data are stored. A communication processing unit 34 that exchanges information and instructions with the ROM 33 and the operation panel 15 is provided. In the door control device 13, the control program and the like stored in the ROM 33 can be updated later by connecting to a personal computer and the like.

  In order to manage and control the display of the liquid crystal panel 17 and the operation of the slide door 4 to the CPU 31, the panel operation management unit (operation unit operation management unit) 35, display instruction unit 36, customization management unit 37, door operation control Each functional unit of the unit (opening / closing body operation control unit) 38 is provided. In the CPU 31, the panel operation management unit 35 controls the operation of the panel drive motor 19 and controls the positions (P, Q, R) of the operation panel 15. The display instructing unit 36 displays information necessary for determining the display to be displayed on the liquid crystal panel 17 with respect to the operation panel 15, for example, the current operation state (full closing, full opening, in operation) of the slide door 4 and the vehicle speed To provide information. In addition, the display instruction unit 36 manages the state (activation, standby, sleep, illuminance, etc.) of the liquid crystal panel 17 according to the current state of the vehicle (during traveling, return mode, brightness of vehicle interior, etc.) . The customization management unit 37 manages customization operations from an external device such as a smartphone, such as the opening / closing speed and opening amount of a door, and ON / OFF of a child lock. The door operation control unit 38 controls the drive unit 8 in accordance with the operation content of the user on the operation panel 15 and operates the slide door 4.

  On the other hand, on the operation panel 15 side, the display management unit 41, the user operation detection unit 42, and the operation content determination unit 43 are used to display the liquid crystal panel 17 or transmit the user's operation content to the control unit 16 side. The sensor signal detection unit 44, the external device communication unit 45, and the communication processing unit 46 are provided. The display management unit 41 of the operation panel 15 controls the display of the liquid crystal panel 17 based on the current operation state of the slide door 4 and the like sent from the display instruction unit 36 of the control unit 16. FIG. 7 is a table showing the relationship between the current operating state of the slide door 4 and the traveling state of the vehicle and the display of the liquid crystal panel 17. When the slide door 4 is in the operating state as in the left column, the liquid crystal panel 17 is shown. The display in the right column appears on.

  As shown in FIG. 7, in the operation panel 15, when the slide door 4 is fully closed and the vehicle speed is 0, the display management unit 41 having received the information “OPEN” and “picture of the key” on the liquid crystal panel 17 (lock Or unlock) is displayed. Further, when the slide door 4 is in the opening and closing operation, all "OPEN", "CLOSE", "return", and "picture of key" are displayed. Similarly, when the slide door 4 is fully open and the vehicle speed is 0, “CLOSE”, “Return home”, and “Picture of key” are displayed. Furthermore, from the display instruction unit 36, when the vehicle is traveling or after the return mode is performed, an instruction of “turn off” not to be displayed is sent. At this time, the liquid crystal panel 17 is not displayed, and the operation is invalidated even if the user touches the liquid crystal panel 17. In addition, when customization operation is being performed from an external device, etc., character display (for example, "during external device communication", "customization complete") is displayed based on an instruction from display instruction unit 36 Be done.

  The user operation detection unit 42 detects whether the display on the liquid crystal panel 17 has been operated (touched) by the user. When the user operates the liquid crystal panel 17, the operation content determination unit 43 receives the detection result of the user operation detection unit 42 and determines the operation content. That is, for example, while the slide door 4 is opening and closing, four buttons are displayed, but when the user touches any display, the user operation detection unit 42 detects it and which display it is. The operation content determination unit 43 determines whether or not there is any. The determination result of the operation content determination unit 43 is sent to the control unit 16 via the communication processing unit 46 that exchanges information and instructions with the control unit 16. If the determination result at that time is, for example, "OPEN", that effect is transmitted to the door operation control unit 38, the electric motor 14 of the drive unit 8 is driven, and the slide door 4 operates in the opening direction.

Further, the operation content determination unit 43 also determines whether an adult or a child performs the panel operation. FIG. 8 is an explanatory view showing determination criteria for identifying an adult and a child. Here, the two are distinguished by focusing on the difference in size between the adult and the child's finger. As shown in FIG. 8, when the button display 51 is displayed on the liquid crystal panel 17, when an adult operates it, the finger touches an area of about the outer frame A in general. On the other hand, when the child performs an operation, the finger touches an area of about the inner frame C because the finger is small. Therefore, a threshold Z (for example, 2 cm ² ) for identifying an adult and a child is provided between frames A and C, and if an area larger than the threshold Z is detected, "adult", if less than that, "child" It is determined that As a result, apart from the so-called "child lock" in which the door can not be opened from the inside, a door opening / closing control that distinguishes between an adult and a child becomes possible. Child locks are often left as they are once set, and even if an adult is riding, it is inconvenient to be able to open the door from inside the car if the setting is made, but such identification is performed This makes it possible to eliminate such inconvenience.

  Output signals of the human sensor 23 and the illumination sensor 25 are input to the sensor signal detection unit 44. The sensor signal detection unit 44 having received the output signal from each of the sensors 23 and 25 transmits the detected signal to the control unit 16 via the communication processing unit 46. In the control unit 16 having received this, when the operation panel 15 is at the storage position P and the output signal of the human sensor 23 is received, the panel operation management unit 35 operates the panel drive motor 19 to operate it. The panel 15 is moved to the in-vehicle operation position Q. Thus, when the hand approaches the operation panel 15 in the stored state, the operation panel 15 rises from the inside of the door panel 22 and the liquid crystal panel 17 appears in the car. Further, the output signal of the illuminance sensor 25 is sent to the display instructing unit 36, and the illuminance control signal is sent from the display instructing unit 36 to the operation panel 15 side in order to adjust the illuminance of the liquid crystal panel 17 according to the brightness in the car. Be Thereby, the illuminance of the liquid crystal panel 17 is adjusted based on the brightness in the car, and the screen display easy for the user to view is maintained.

  The external device communication unit 45 receives an instruction from the external device 47 such as a smartphone and transmits the content to the control unit 16 side. Here, first, when the external device communication unit 45 recognizes an instruction (interruption) from the external device 47, that effect is transmitted to the control unit 16 side. The customization management unit 37 of the control unit 16 determines whether the instruction is access from a valid external device or not by checking the password or the like, and if the instruction is valid, the external device communication unit 45 sends the external device Allow communication with 47. The permitted external device communication unit 45 receives an instruction from the external device 47. The external device communication unit 45 having received the instruction from the external device 47 notifies the control unit 16 side of the content. At that time, the display instruction unit 36 of the control unit 16 instructs the display management unit 41 of the operation panel 15 to display "during external device communication", and that effect is displayed on the liquid crystal panel 17.

  When the instruction content of the external device 47 is transmitted from the operation panel 15 side, the customization management unit 37 receives it on the control unit 16 side, writes the contents of the RAM 32 and the ROM 33, and the customization is completed. When the customization is completed, the display instruction unit 36 instructs the display management unit 41 to display "completion of customization", and the liquid crystal panel 17 displays that effect. As customization by an external device, for example, opening / closing speed of door (MIN, NORMAL, MAX), opening amount (package, second row, third row), child lock ON / OFF, identification by adult and child finger area and so on. In this case, the opening amount "package" is a mode in which the door is opened small (for example, about 30 cm) for the purpose of carrying out loading and unloading of the package without people getting on and off. Further, the second and third rows mean that the door is opened to the position of the second and third rows of seats in the car, respectively, and the third row may be the same position as the fully open.

  When such customization is performed, the open / close state of the slide door 4 can be controlled from an application installed on an external device such as a smartphone. For example, when the “second row” is specified as the opening amount from the smartphone application, even if the display of “OPEN” is operated, the slide door 4 does not open until it is fully opened, and stops at the position of the sheet in the second row. By performing such customization, it is possible to prevent the door from opening up to the third row even if the child is on the third row of sheets, and to prevent the child from jumping out of the vehicle with the door open. Also, by setting the opening / closing speed of the door to "MIN", it is possible for those with slow operation to get on and off safely. In addition, cancellation of customization can also be easily performed from the application of the smartphone.

  In such a door control device 13, for example, opening and closing of the door is performed from the inside of the vehicle in the following manner. First, when getting on the vehicle 1 and closing the slide door 4, the liquid crystal panel 17 of the operation panel 15 is 3 of “CLOSE”, “picture of key”, and “return” as the door is fully opened (and vehicle speed 0). One is displayed (see FIG. 7). Therefore, when trying to close the slide door 4, the user touches “CLOSE” displayed on the liquid crystal panel 17. At this time, in the operation panel 15, the user operation detection unit 42 detects the user's operation, and the operation content determination unit 43 determines that the operation content is “CLOSE”. The determination result is sent to the control unit 16 through the communication processing unit 46, and the door operation control unit 38 drives the electric motor 14 of the drive unit 8 based on the determination result, and the slide door 4 operates in the closing direction. Do.

  When the slide door 4 is completely closed and the vehicle 1 starts to run, the display instruction unit 36 of the control unit 16 recognizes that the vehicle is currently traveling based on information from a vehicle speed sensor (not shown). The display instruction unit 36 that has recognized that the vehicle is traveling instructs the display management unit 41 to “turn off” in order to put the liquid crystal panel 17 in the standby (standby) state. The display management unit 41 receives the instruction of “light off”, the liquid crystal panel 17 is turned off, and the display of the liquid crystal panel 17 is thereby turned off. Further, in the control unit 16, the panel operation management unit 35 similarly recognizes that the vehicle is traveling, and causes the panel drive motor 19 to store the operation panel 15 in the storage position P.

  Thereafter, when the vehicle arrives at the destination and the user opens the slide door 4, the user brings his hand close to the operation panel 15 stored in the storage position P. Then, the human sensor 23 detects it and outputs a detection signal to the sensor signal detection unit 44. The sensor signal detection unit 44 that has received the output signal transmits that effect to the panel operation management unit 35 of the control unit 16. In response to this, the panel operation management unit 35 operates the panel drive motor 19 to move the operation panel 15 to the in-vehicle operation position Q. As a result, the operation panel 15 in the stored state rises, and the liquid crystal panel 17 faces the user appearing in the car.

  Further, at this time, when the vehicle 1 is stopped, the door open condition of “door fully closed, vehicle speed 0” is satisfied. Therefore, the display management unit 41 that has obtained the information from the display instruction unit 36 of the control unit 16 displays “OPEN” and “picture of key” on the liquid crystal panel 17. At this time, the display instruction unit 36 controls the display management unit 41 based on the output signal of the illuminance sensor 25 to appropriately adjust the illuminance of the liquid crystal panel 17 according to the brightness in the car. On the other hand, when the vehicle 1 is not stopped, the door opening condition is not satisfied, and the display instruction unit 36 does not provide the information of "door opening condition satisfied", and the liquid crystal panel 17 is "opened". Does not appear. Therefore, although the vehicle is still traveling, the safety of the occupant can be ensured without opening the door. In an emergency, the door can be opened by using the above-mentioned latch release lever 24.

  When "OPEN" and "Picture of the key" are displayed on the liquid crystal panel 17 and the door lock is released (when "Picture of the key" is in the unlocked state), the user "OPEN" When the button display of is touched, the user operation detection unit 42 detects the user's operation, and the operation content determination unit 43 determines that the operation content is “OPEN”. The determination result is sent to the control unit 16 via the communication processing unit 46, and the door operation control unit 38 drives the drive unit 8 based on the determination result, and the slide door 4 operates in the opening direction.

  In addition, when the user does not release the door lock (when the "picture of the key" is in the locked state) and the user touches the button display of "OPEN", the user operation detection unit 42 detects this operation. Based on the detection result, the door operation control unit 38 determines an error, and an error is displayed on the liquid crystal panel 17 (a warning sound may be emitted at the same time). If such an error display appears, touch the "key picture" again to release the lock. When the user touches the button display of "picture of key", the user operation detection unit 42 detects the user's operation, and the operation content determination unit 43 determines that the operation content is "unlocking" . The determination result is sent to the control unit 16 through the communication processing unit 46, and the door operation control unit 38 operates the door lock mechanism based on the determination result to bring the slide door 4 into the unlocked state. In addition, locking of the slide door 4 is implemented by the same process.

  In addition, when “identification for adults and children” is set, even if the user touches the button display of “OPEN” in the unlocked state, if it is a child operation, the operation content determination unit 43 From the contact area of the finger, it is determined that the operation is "child", and the operation is invalidated. That is, the determination result "OPEN" is not sent to the control unit 16. As a result, even if the child touches the "OPEN" display, the door operation control unit 38 does not respond, and the slide door 4 does not open. Such "adult / child identification" is similarly performed in the "CLOSE" display when the door is closed, and can prevent the child from inadvertently closing the door. Therefore, easy door operation by the child can be prevented, and the safety of the user can be improved.

  When the user opens the slide door 4 and goes out of the vehicle, it becomes necessary to close the slide door 4 this time. At that time, in the door control device 13, by moving the operation panel 15 to the operation position R outside the vehicle, the liquid crystal panel 17 can be disposed at a position where it is easy to operate from outside the vehicle. Movement from the in-vehicle operation position Q to the out-of-vehicle operation position R is basically performed manually, but it is also possible to provide an operation switch on the operation panel 15 or electrically operate by an instruction from an external device is there. When the slide door 4 is open, "CLOSE", "Picture of key", and "Return" are displayed on the liquid crystal panel 17, move the operation panel 15 to the operation position R outside the vehicle, and then "CLOSE" By the operation, as described above, the operation is detected and the slide door 4 operates in the closing direction.

  On the other hand, when the vehicle 1 arrives at a home garage etc., when there are a lot of luggage or holding a child, it is often convenient if the door is locked as it is when the slide door 4 is closed. . In such a situation, when the slide door 4 is closed, by operating the "return", the slide door 4 is closed and the door is also locked. At this time, in consideration of the situation in which the package or the child is taken down, when "Return" is touched, the door closing operation may be started with a time lag of, for example, about 10 seconds instead of closing the door immediately. . When such a "return mode" is performed, the door control device 13 then enters the sleep state (power saving state where power consumption is almost zero).

  Thus, in the door control device 13 according to the present invention, an operation panel provided with the liquid crystal panel 17 in such a manner that a door lock switch and a door handle are integrated with the door panel 22 of the slide door 4 instead of the conventional handle. The provision of 15 makes it possible to reduce the size and weight of the door opening / closing operation parts. In addition, since the parts and members in the slide door 4 are reduced, the layout in the door can be improved. Furthermore, the slide door can be opened and closed with one touch, and the operation burden on the user is also significantly reduced. In addition, the liquid crystal panel 17 is disposed to face the user as necessary, and only the display capable of operation appears there, and the illuminance is also adjusted according to the brightness in the vehicle. The visibility, operability, and design of the panel 15 can be improved.

It goes without saying that the present invention is not limited to the above-described embodiment, and various changes can be made without departing from the scope of the invention.
For example, although an example using a liquid crystal touch panel of a capacitive type panel as a user interface of the operation panel 15 is shown in the above-mentioned embodiment, an organic EL touch panel, or a display surface that can detect a user's operation. It is also possible to use other types of operation and display devices, such as resistive film type touch panels. In addition to the state in which the vehicle 1 is completely stopped, "vehicle speed 0" in the above-described door open condition may include a speed (for example, less than 5 km per hour) that can be regarded as substantially stopped.

  The opening and closing body control device according to the present invention is applicable not only to the sliding door of the automobile as in the above-described embodiment but also to other opening and closing bodies for vehicles such as a power window and an electric sunroof.
