[First embodiment]
First, a sliding door device 10 according to a first embodiment of the present invention will be described with reference to FIGS. 1 to 5.

  The slide door device 10 according to the first embodiment of the present invention is suitably used for, for example, a slide type door provided on a side surface of a vehicle such as a passenger car. Hereinafter, as an example, an example in which the slide door device 10 is applied to the rear slide door 14 provided on the side surface of the vehicle 12 will be described.

  In the sliding door device 10 of the present embodiment, one end of a pair of link arms 18 is fixed to the rocker portion on the side of the vehicle body so as to be rotatable, and the other end of the link arm 18 is connected to the sliding door 14 by a hinge bracket 20. Each is fixed so as to be freely rotatable. Further, a door motor 22 is provided at a portion where the link arm 18 is fixed to the vehicle body, and the link arm 18 is electrically swinged by the door motor 22.

  The slide door 14 is configured to slide between a position where the door opening 24 is closed by the swing of the pair of link arms 18 and a position where the door opening 24 on the vehicle rear side is opened relative to the door opening 24. .

  The vehicle body (for example, the rocker portion) is provided with a projector 26 as mark display means capable of projecting light such as laser light. The floodlight 26 irradiates a plurality of laser beams at regular intervals on the road surface along a slide locus L through which the outermost part 14A of the slide door 14 (for example, the entire outer panel portion of the slide door 14) passes when viewed from above the vehicle. It is supposed to be.

  A plurality of dot-shaped marks 28 indicating the slide locus L of the outermost 14A of the sliding door 14 assumed when the sliding door 14 slides are displayed on the road surface by the laser light before the sliding operation of the sliding door 14. It is supposed to be.

  In this embodiment, the slide locus L is such that the outermost part 14A passes from the position where the slide door 14 closes the door opening 24 to the position where the door opening 24 on the rear side of the vehicle slides. Specifically, the passage locus L1 through which the front end of the outermost part 14A passes from the position where the sliding door 14 closes the door opening 24 to the outermost side of the vehicle 12 passes, and the sliding door 14 slides to the outermost side of the vehicle 12. And when the sliding door 14 slides to the outermost side of the vehicle 12 and the passing locus L2 along the outermost portion 14A when the link arm 18 is perpendicular to the vehicle longitudinal direction. A passage locus L3 through which the rear end of the outermost part 14A passes through until it slides to a position where the door opening 24 on the vehicle rear side from the door opening 24 opens. It is Ranaru thing.

  In addition to the mark 28, the projector 26 has an end position in the sliding locus of the entire sliding door 14 assumed when the sliding door 14 slides in the door opening direction (that is, the sliding door 14 in the vehicle top view when the door is fully opened). A plurality of dot-like marks 30 indicating the rear end position) are displayed on the road surface. The projector 26 is attached to an appropriate position of the vehicle body so that the marks 26 and 30 can be reliably displayed on the road surface even if the vehicle height changes depending on the vehicle type.

  In the present embodiment, the marks 28 and 30 indicate the outermost part of the movable area of the slide door 14.

  And the sliding door apparatus 10 of this embodiment is provided with the control unit 32 as FIG. 2 shows. An automatic door open / close switch 34 is electrically connected to the input side of the control unit 32, and the projector 26 and the door motor 22 are electrically connected to the output side of the control unit 32. Note that the automatic door opening / closing switch 34 is provided on, for example, the outer side surface of the slide door 14, the side surface of the passenger compartment of the slide door 14, and a remote control switch.

  Next, with reference to the flowcharts shown in FIGS. 3 and 4 as appropriate, the operation and effect of the sliding door device 10 having the above-described configuration will be described together with the operation.

  If the automatic door opening / closing switch 34 is operated to open the door while the slide door 14 is in a position to close the door opening 24, a door opening command signal is output from the automatic door opening / closing switch 34 to the control unit 32. When the control unit 32 determines that the automatic door opening / closing switch 34 has been opened by inputting the door opening command signal from the automatic door opening / closing switch 34 (step S1: YES), the control unit 32 operates the projector 26 to irradiate the laser beam. (Step S2).

  As a result, the mark 28 indicating the slide locus L of the outermost portion 14A of the slide door 14 assumed when the slide door 14 slides in the door opening direction is displayed (projected) on the road surface, and the slide door 14 is opened. A mark 30 is displayed (projected) on the road surface, which indicates the terminal position of the sliding locus of the entire sliding door 14 assumed when sliding in the direction.

  Thus, in the slide door device 10 according to the present embodiment, the light projector 26 uses the marks 28 and 30 indicating the slide trajectory of the entire slide door 14 assumed when the slide door 14 slides in the door opening direction on the road surface. indicate. Therefore, the occupant can grasp in advance the slide locus (movable region) of the entire slide door 14 before the door opening operation of the slide door 14 by the marks 28 and 30 displayed on the road surface by the projector 26. Accordingly, it is possible to directly confirm the presence or absence of an obstacle on the slide locus of the entire slide door 14 based on the marks 28 and 30 displayed on the road surface.

  Further, like the slide door device 10 according to the present embodiment, the slide door 14 is slid by swinging the pair of link arms 18, so that the slide is different from the hinge type swing door or the roller type slide door. Even when a trajectory is drawn, the presence or absence of an obstacle on the slide trajectory of the entire sliding door 14 can be directly visually confirmed based on the marks 28 and 30 displayed on the road surface.

  Further, in the slide door device 10 according to the present embodiment, the mark 28 displayed on the road surface by the projector 26 is the slide locus L of the outermost 14A of the slide door 14 assumed when the slide door 14 slides in the door opening direction. Located on the top. Therefore, it can be determined whether or not the outermost part 14A of the sliding door 14 collides with the obstacle (that is, if there is an obstacle on the line of the slide locus L or within the frame, the obstacle collides with the sliding door 14). Can be judged). Thereby, the movable area of the whole slide door 14 becomes clear, and it becomes easier to confirm the presence or absence of an obstacle on the slide locus of the whole slide door 14.

  Further, in the slide door device 10 according to the present embodiment, the projector 26 indicates the end position in the slide trajectory of the entire slide door 14 assumed when the slide door 14 slides in the door opening direction in addition to the mark 28. The mark 30 is displayed on the road surface. Therefore, it is possible to determine whether or not there is an obstacle at the end position in the sliding locus of the entire sliding door 14 by the mark 30 displayed on the road surface. Accordingly, it is possible to check whether there is an obstacle that may collide until the door opening operation of the slide door 14 is completed.

  Then, the control unit 32 operates the automatic door motor 22 to rotate the pair of link arms 18 (step S3). Thereby, the slide door 14 starts to slide from the position where the door opening 24 is closed to the vehicle rear side from the door opening 24.

  On the other hand, when the automatic door opening / closing switch 34 is closed when the sliding door 14 is at a position where the door opening 24 is opened (that is, a position where the sliding door 14 is slid rearward), a door closing command signal is sent from the automatic door opening / closing switch 34 to the control unit 32. Is output. When the control unit 32 determines that the automatic door open / close switch 34 has been closed by inputting a door open command signal from the automatic door open / close switch 34 (step S11: YES), the light projector 26 is activated to emit laser light. (Step S12).

  Thereby, the mark 28 indicating the slide locus L of the outermost part 14A of the slide door 14 assumed when the slide door 14 slides in the door closing direction is displayed (projected) on the road surface. Even when the slide door 14 slides in the door closing direction, the mark 30 is displayed (projected) on the road surface.

  As described above, in the sliding door device 10 according to the present embodiment, even when the sliding door 14 slides in the door closing direction, the projector 26 is assumed when the sliding door 14 slides in the door closing direction. A mark 28 indicating the entire 14 slide track is displayed on the road surface. Accordingly, as in the case of the door opening operation, the presence or absence of an obstacle on the slide trajectory of the entire slide door 14 can be directly visually confirmed based on the mark 28 displayed on the road surface.

  Then, the control unit 32 operates the automatic door motor 22 to rotate the pair of link arms 18 (step S13). Thereby, the slide door 14 starts to slide from the position where the door opening 24 is opened to the side where the door opening 24 is closed.

  Next, a modification of the first embodiment of the present invention will be described.

  In the above embodiment, the projector 26 displays the mark 28 on the road surface along the slide path L through which the outermost part 14A of the slide door 14 (for example, the entire outer panel portion of the slide door 14) passes in the vehicle top view. However, it may be as follows.

  That is, the mark 28 may be displayed on the road surface along the outer side of the slide locus L through which the outermost part 14A of the slide door 14 (for example, the entire outer panel portion of the slide door 14) passes when viewed from the top of the vehicle. good. Similarly, the mark 30 may be displayed on the road surface at a position on the rear side of the vehicle with respect to the end position in the sliding locus of the entire sliding door 14 assumed when the sliding door 14 slides in the door opening direction.

  That is, the sliding locus of the sliding door 14 assumed when the sliding door 14 slides has a margin with respect to the actual sliding locus, and the marks 28 and 30 are displayed on the road surface along the sliding locus. Anyway.

  Moreover, in the said embodiment, although the light projector 26 irradiated the laser beam and demonstrated the marks 28 and 30 displayed on a road surface, as shown in FIG. 5, the light projector 26 is each mark. A linear mark 44 may be displayed on the road surface by irradiating laser light so that 28 and 30 are continuous. In this case, only the mark 44 may be displayed, or the dotted marks 28 and 30 and the mark 44 may be displayed at the same time (in this case, for example, the marks 28 and 30 are better than the mark 44). Also has high brightness).

  In the above embodiment, the slide door 14 is configured to be electrically slid by the door motor 22. However, the slide door 14 is configured to be manually slidable, and the mark is also displayed when the slide door 14 is slid manually. Of course, 28 and 30 may be displayed on the road surface.

  In the above embodiment, when the automatic door opening / closing switch 34 is operated, the projector 26 displays the marks 28 and 30 on the road surface. However, a switch for displaying the marks 28 and 30 on the road surface separately. When the switch is operated, the projector 26 may display the marks 28 and 30 on the road surface (for example, the marks 28 and 30 are displayed on the road surface in response to the reverse of the gear). You may do it).

  In this case, for example, if the marks 28 and 30 are displayed on the road surface during warehousing, the determination of the positional relationship between the parking space and the sliding trajectory of the sliding door 14 (determination of whether there is room in the door opening space). It becomes possible to do. It is also possible to notify the person outside the vehicle of the slide locus of the slide door 14.

  In the above embodiment, the projector 26 displays a plurality of marks 28 and 30 on the road surface at the same time. However, for example, the light projector 26 may blink sequentially in accordance with the operation direction of the slide door 14. Further, the plurality of marks 26 and 30 may be blinked at the same time to alert the driver or a person outside the vehicle. Further, the entire movable region of the slide door 14 (that is, the entire area within the frame of the slide locus L) may be displayed on the road surface.

[Second Embodiment]
Next, a sliding door device 60 according to a second embodiment of the present invention will be described with reference to FIGS.

  The slide door device 60 according to the second embodiment of the present invention is obtained by adding a camera 36 and a screen display 38 to the slide door device 10 according to the first embodiment. Hereinafter, about 2nd embodiment of this invention, a different structure from the sliding door apparatus 10 which concerns on said 1st embodiment is demonstrated, and the same code | symbol is used about the same structure as the sliding door apparatus 10 which concerns on said 1st embodiment. The explanation is omitted.

  In the sliding door device 60 according to the second embodiment of the present invention, the door mirror 48 of the vehicle 12 is provided with a camera 36 as image receiving means. The camera 36 receives the marks 28 and 30 displayed on the road surface by the projector 26 and the peripheral area of the slide door 14 where the marks 28 and 30 are located, as indicated by a two-dot difference line L4 in FIG. It has become.

  In the slide door device 60 according to the second embodiment of the present invention, for example, a screen display 38 (superimposed screen display means) of a navigation system is provided in the vehicle 12. The screen display 38 displays the video from the main body of the navigation system on the screen and switches the video input so that the marks 28 and 30 received by the camera 36 and the slide on which the marks 28 and 30 are located. The peripheral area of the door 14 can be displayed superimposed on the screen.

  In the sliding door device 60 of the present embodiment, as shown in FIG. 7, the automatic door opening / closing switch 34 and the camera 36 are electrically connected to the input side of the control unit 32, and the output of the control unit 32. On the side, the projector 26, the screen display 38, and the door motor 22 are electrically connected.

  Next, with reference to the flowcharts shown in FIGS. 8 and 9 as appropriate, the operation and effect will be described together with the operation of the sliding door device 60 configured as described above.

  If the automatic door opening / closing switch 34 is operated to open the door while the slide door 14 is in a position to close the door opening 24, a door opening command signal is output from the automatic door opening / closing switch 34 to the control unit 32. When the control unit 32 determines that the automatic door open / close switch 34 has been opened by inputting the door open command signal from the automatic door open / close switch 34 (step S21: YES), the projector 26 is activated to irradiate the laser beam. (Step S22).

  As a result, the mark 28 indicating the slide locus L of the outermost portion 14A of the slide door 14 assumed when the slide door 14 slides in the door opening direction is displayed (projected) on the road surface, and the slide door 14 is opened. A mark 30 is displayed (projected) on the road surface, which indicates the terminal position of the sliding locus of the entire sliding door 14 assumed when sliding in the direction.

  Subsequently, the control unit 32 operates the camera 36 to move the marks 28 and 30 displayed on the road surface by the projector 26 and the slide on which the marks 28 and 30 are positioned, as indicated by the two-dot chain line L4 in FIG. The peripheral area of the door 14 is received. Further, the control unit 32 outputs a display signal to the screen display 38 based on the video signal from the camera 36 (step S23).

  Then, the control unit 32 operates the automatic door motor 22 to rotate the pair of link arms 18 (step S34). Thereby, the slide door 14 starts to slide from the position where the door opening 24 is opened to the side where the door opening 24 is closed.

  Next, a modification of the second embodiment of the present invention will be described.

  In the embodiment described above, the marks 28 and 30 indicating the slide locus of the slide door 14 are dotted, and the mark 28 and 30 and the peripheral area of the slide door 14 where the mark 28 and 30 are located are superimposed on the screen display 38. As shown in FIG. 11, a linear mark 44 indicating the sliding locus of the sliding door 14 is displayed on the road surface, and the linear mark 44 and the mark 44 are located. The peripheral area of the slide door 14 may be displayed on the screen superimposed on the screen display 38. In this case, only the mark 44 may be displayed, or the dotted marks 28 and 30 and the mark 44 may be displayed simultaneously (in this case, for example, the marks 28 and 30 are more than the mark 44). Also has high brightness).

  Note that in the second embodiment of the present invention, other modifications are the same as those in the first embodiment, so the description thereof is omitted with reference to the description of the first embodiment.

[Third embodiment]
Next, a sliding door device 70 according to a third embodiment of the present invention will be described with reference to FIGS. 6 and 12 to 16.

  The sliding door device 70 according to the third embodiment of the present invention is obtained by further adding a warning indicator 40 and a warning sound generator 42 as warning means to the sliding door device 60 according to the second embodiment. Hereinafter, about 3rd embodiment of this invention, a different structure from the sliding door apparatus 60 which concerns on said 2nd embodiment is demonstrated, and the same code | symbol is used about the same structure as the sliding door apparatus 60 which concerns on said 2nd embodiment. The explanation is omitted.

  In the sliding door device 70 according to the third embodiment of the present invention, a warning indicator 40 and a warning sound generator 42 are provided at predetermined positions of the vehicle body (for example, the pillar, the outer surface of the sliding door 14, etc.). . The warning indicator 40 lights up or blinks to display a warning when it is determined that the obstacle 50 is present on the slide trajectory of the entire slide door 14, and the warning sound generator 42 displays the warning information of the entire slide door 14. A warning sound is generated when it is determined that the obstacle 50 exists on the slide track.

  In the sliding door device 70 of the present embodiment, as shown in FIG. 12, the automatic door opening / closing switch 34 and the camera 36 are electrically connected to the input side of the control unit 32, and the output of the control unit 32. On the side, the projector 26, the screen display 38, the warning display 40, the warning sound generator 42, and the door motor 22 are electrically connected.

  Next, with reference to the flowcharts shown in FIGS. 13 and 14 as appropriate, the operation and effect of the slide door device 70 having the above configuration will be described together with the operation.

  If the automatic door opening / closing switch 34 is operated to open the door while the slide door 14 is in a position to close the door opening 24, a door opening command signal is output from the automatic door opening / closing switch 34 to the control unit 32. When the control unit 32 determines that the automatic door opening / closing switch 34 has been operated to open the door by inputting a door opening command signal from the automatic door opening / closing switch 34 (step S41: YES), the projector 26 is activated to emit laser light. (Step S42).

  As a result, the mark 28 indicating the slide locus L of the outermost portion 14A of the slide door 14 assumed when the slide door 14 slides in the door opening direction is displayed (projected) on the road surface, and the slide door 14 is opened. A mark 30 is displayed (projected) on the road surface, which indicates the terminal position of the sliding locus of the entire sliding door 14 assumed when sliding in the direction.

  Subsequently, the control unit 32 operates the camera 36 to move the marks 28 and 30 displayed on the road surface by the projector 26 and the slide on which the marks 28 and 30 are positioned, as indicated by the two-dot chain line L4 in FIG. The peripheral area of the door 14 is received. Further, the control unit 32 outputs a display signal to the screen display 38 based on the video signal from the camera 36 (step S43). When the display signal from the control unit 32 is input to the screen display 38, for example, as shown in FIG. 10, the marks 28 and 30 received by the camera 36 and the slide door 14 where the marks 28 and 30 are located are displayed. The surrounding area is displayed superimposed on the screen.

  Then, the control unit 32 inputs and analyzes the display images of the marks 28 and 30 received by the camera 36. Subsequently, the control unit 32 displays the display images (display state) of the marks 28 and 30 received by the camera 36 and the display images of the reference marks assumed in advance when the slide door 14 slides (the obstacle 50 is displayed). Differences from the display images of the marks 28 and 30 when there is no mark and corresponding to the reference trajectory are respectively compared (step S44). Whether there is a difference between the display image of each mark 28, 30 and the display image of each reference mark (the display image of each mark 28, 30 received by the camera 36 with respect to the display image of each reference mark). By determining whether or not the marks 28 and 30 are missing, it is determined whether or not the obstacle 50 exists on the slide trajectory of the entire sliding door 14 (step S45).

  That is, if there is an obstacle 50 on the line of the slide trajectory L or in the frame, the obstacle 50 causes a loss of the marks 28 and 30, thereby determining that the obstacle 50 exists on the line of the slide trajectory L or in the frame. can do.

  Thus, in the slide door device 70 according to the present embodiment, the display image of each mark 28, 30 received by the camera 36 and the display image of each reference mark assumed in advance when the slide door 14 slides. The presence of the obstacle 50 on the slide trajectory of the entire slide door 14 is determined by comparing the differences. Therefore, even if it is difficult for the occupant to confirm the presence of the obstacle 50 by direct visual observation, it is possible to determine the presence or absence of the obstacle 50 on the slide trajectory of the entire slide door 14.

  Further, like the slide door device 70 according to the present embodiment, the slide door 14 is slid by the swing of the pair of link arms 18, so that a specific slide different from the hinge type swing door or the roller type slide door is obtained. Even when a trajectory is drawn, it is possible to determine the presence or absence of the obstacle 50 on the slide trajectory of the entire slide door 14.

  When the control unit 32 determines that there is no difference between the display images of the marks 28 and 30 and the display images of the reference marks (step S45: NO), the control unit 32 operates the automatic door motor 22 to set a pair of images. The link arm 18 is rotated (step S46). Thereby, the slide door 14 starts to slide from the position where the door opening 24 is closed to the vehicle rear side from the door opening 24.

  In the slide door device 70 according to the present embodiment, as described above, the screen display 38 superimposes the marks 28 and 30 received by the camera 36 and the peripheral area of the slide door 14 where the marks 28 and 30 are located. And display it on the screen. Accordingly, the occupant can check the presence or absence of the obstacle 50 on the slide locus of the entire slide door 14 based on the marks 28 and 30 displayed on the road surface while watching the superimposed image on the screen display 38 in the passenger compartment. Is possible.

  Further, in the slide door device 70 according to the present embodiment, the light projector 26 has marks 28 and 30 indicating the slide trajectory of the entire slide door 14 assumed when the slide door 14 slides in the door opening direction as described above. Display on the road surface. Therefore, the occupant can also visually confirm the presence or absence of the obstacle 50 on the slide trajectory of the entire slide door 14 based on the marks 28 and 30 displayed on the road surface.

  On the other hand, when the control unit 32 determines that there is a difference between the display image of each mark 28, 30 and the display image of each reference mark in the process of step S45 (step S45: YES), A warning is activated (step S47). That is, the warning indicator 40 is turned on or blinked to display a warning, and a warning sound is generated from the warning sound generator 42 (other generators such as odor and vibration may be used in combination). Thereby, it is possible to make the occupant recognize that there is an obstacle 50 on the slide trajectory of the entire slide door 14. Accordingly, when the occupant operates the automatic door opening / closing switch 34 to stop the door, the automatic door motor 22 is stopped, whereby the collision between the slide door 14 and the obstacle 50 can be prevented.

  In the process of step S47, the warning indicator 40 is turned on or blinked to display a warning, and a warning sound is generated from the warning sound generator 42. At the same time, the automatic door motor 22 performs the automatic door opening operation of the slide door 14. The door opening operation of the sliding door 14 motor by the door motor 22 may be prohibited. Alternatively, the automatic door motor 22 may be decelerated to slow the door opening operation of the slide door 14, or the automatic door motor 22 may be reversed to slide the slide door 14 in the door closing direction. In this way, the collision between the slide door 14 and the obstacle 50 can be prevented.

  On the other hand, when the automatic door opening / closing switch 34 is closed when the sliding door 14 is at a position where the door opening 24 is opened (that is, a position where the sliding door 14 is slid rearward), a door closing command signal is sent from the automatic door opening / closing switch 34 to the control unit 32. Is output. When the control unit 32 determines that the automatic door opening / closing switch 34 has been closed by inputting a door opening command signal from the automatic door opening / closing switch 34 (step S51: YES), the projector 26 is activated to emit laser light. (Step S52).

  Thereby, the mark 28 indicating the slide locus L of the outermost part 14A of the slide door 14 assumed when the slide door 14 slides in the door closing direction is displayed (projected) on the road surface. Even when the slide door 14 slides in the door closing direction, the mark 30 is displayed (projected) on the road surface.

  Subsequently, the control unit 32 operates the camera 36 to receive images of the marks 28 and 30 displayed on the road surface by the projector 26 and the peripheral area of the slide door 14 where the marks 28 and 30 are located. Further, the control unit 32 outputs a display signal to the screen display 38 based on the video signal from the camera 36 (step S53). When the display signal from the control unit 32 is input, the screen display 38 displays the marks 28 and 30 received by the camera 36 and the peripheral area of the slide door 14 where the marks 28 and 30 are located on the screen. To do.

  Then, the control unit 32 inputs and analyzes the display images of the marks 28 and 30 received by the camera 36. Subsequently, the control unit 32 displays the display images of the marks 28 and 30 received by the camera 36 and the display images of the reference marks assumed in advance when the slide door 14 slides (each of the cases when there is no obstacle 50). The differences from the display images of the marks 28 and 30 are compared (step S54). Whether there is a difference between the display image of each mark 28, 30 and the display image of each reference mark (the display image of each mark 28, 30 received by the camera 36 with respect to the display image of each reference mark). By determining whether or not the marks 28 and 30 are missing, it is determined whether or not the obstacle 50 exists on the slide locus of the entire slide door 14 (step S55).

  That is, if there is an obstacle 50 on the line of the slide trajectory L or in the frame, the obstacle 50 causes a loss of the marks 28 and 30, thereby determining that the obstacle 50 exists on the line of the slide trajectory L or in the frame. can do. In addition, the analysis means is comprised by the process of step S45 and step S55 which the control unit 32 performs.

  As described above, in the slide door device 70 according to the present embodiment, when the slide door 14 is closed, the display images of the marks 28 and 30 received by the camera 36 and the slide door 14 slide in advance. The presence of the obstacle 50 on the slide trajectory of the entire slide door 14 is determined by comparing the difference between the assumed display images of the reference marks. Therefore, even if it is difficult for the occupant to confirm the presence of the obstacle 50 by direct visual observation, it is possible to determine the presence or absence of the obstacle 50 on the slide trajectory of the entire slide door 14.

  When the control unit 32 determines that there is no difference between the display images of the marks 28 and 30 and the display image of the reference marks (step S55: NO), the control unit 32 operates the automatic door motor 22 to set a pair of images. The link arm 18 is rotated (step S56). Thereby, the slide door 14 starts to slide from the position where the door opening 24 is opened to the side where the door opening 24 is closed.

  In the slide door device 70 according to the present embodiment, as described above, the screen display 38 superimposes the marks 28 and 30 received by the camera 36 and the peripheral area of the slide door 14 where the marks 28 and 30 are located. And display it on the screen. Accordingly, the occupant can check the presence or absence of the obstacle 50 on the slide locus of the entire slide door 14 based on the marks 28 and 30 displayed on the road surface while watching the superimposed image on the screen display 38 in the passenger compartment. Is possible.

  Further, in the slide door device 70 according to the present embodiment, the light projector 26 has the mark 28 indicating the slide trajectory of the entire slide door 14 assumed when the slide door 14 slides in the door closing direction on the road surface as described above. indicate. Therefore, the occupant can also visually confirm the presence or absence of the obstacle 50 on the slide trajectory of the entire slide door 14 based on the mark 28 displayed on the road surface.

  On the other hand, when the control unit 32 determines that there is a difference between the display image of each mark 28, 30 and the display image of each reference mark in the process of step S55 (step S55: YES), A warning is activated (step S57). That is, the warning indicator 40 is turned on or blinked to display a warning, and a warning sound is generated from the warning sound generator 42. Thereby, it is possible to make the occupant recognize that there is an obstacle 50 on the slide trajectory of the entire slide door 14. Accordingly, the automatic door motor 22 is stopped when the passenger operates the automatic door open / close switch 34 to stop the door, thereby preventing the sliding door 14 and the obstacle 50 from colliding even when the sliding door 14 is closed. it can.

  At this time, in the process of step S57, the warning indicator 40 is turned on or blinked to display a warning, and a warning sound is generated from the warning sound generator 42, and at the same time, the automatic door closing operation of the slide door 14 by the automatic door motor 22 is performed. May be prohibited, or the door closing operation of the sliding door 14 motor by the door motor 22 may be stopped. Alternatively, the automatic door motor 22 may be decelerated to slow down the door closing operation of the slide door 14, or the automatic door motor 22 may be reversed to slide the slide door 14 in the door opening direction. In this way, the collision between the slide door 14 and the obstacle 50 can be prevented.

  Note that the collision prevention means is configured by the processing of step S47 and step S57 performed by the control unit 32.

  Next, a modification of the third embodiment of the present invention will be described.

  In the above embodiment, it is determined whether or not the obstacle 50 exists on the slide trajectory of the entire slide door 14 based on the comparison between the dotted marks 28 and 30 and the dotted reference marks. Whether or not the obstacle 50 exists on the slide trajectory of the entire sliding door 14 may be determined based on a comparison between the linear mark 44 (see FIG. 11) and the linear reference mark.

  In the above-described embodiment, whether or not the obstacle 50 exists on the slide trajectory of the entire slide door 14 is determined for each mark 28, 30 received by the camera 36 with respect to the display image of each reference mark. Although the determination is made based on whether or not the marks 28 and 30 are missing in the display image, the following may be performed.

  That is, based on determining the difference between the coordinate position in the display image of each mark 28, 30 received by the camera 36 and the coordinate position in the display image of each reference mark assumed in advance when the slide door 14 slides. Thus, it may be determined whether or not the obstacle 50 exists on the slide locus of the entire slide door 14.

  Further, in the above-described embodiment, during the automatic door opening operation, the marks 28 and 30 indicating the slide locus L of the entire sliding door assumed when the sliding door 14 slides are displayed (projected) on the road surface in the process of step S42. Then, in the process of step S43, the marks 28 and 30 received by the camera 36 and the peripheral area of the slide door 14 where the marks 28 and 30 are located are superimposed on the screen and immediately displayed in step S44. In the above process, the control unit 32 inputs and analyzes the display images of the marks 28 and 30 received by the camera 36. However, the following may be performed.

  That is, as shown in the process of FIG. 15 which is a modified example of the process of FIG. 13, the marks 28 and 30 received by the camera 36 in the process of step S43-1 and the marks 28, The peripheral area of the slide door 14 where 30 is located may be displayed superimposed on the screen, and then the timer may be activated (step S43-2). In step S45-2, until the count value T of the timer reaches a predetermined count value T1, the control unit 32 displays a difference between the display image of each mark 28, 30 and the display image of each reference mark. Even if it is determined that there is (step S45-1: YES), the process may return to the process of step S44 without shifting to the process of operating the warning of step S47.

  Similarly, as shown in the process of FIG. 16 which is a modification of the process of FIG. 14, the marks 28 and 30 received by the camera 36 and the mark 28 in the process of step S53-1 during the automatic door closing operation. , 30 may be displayed in a superimposed manner on the screen, and then the timer may be activated (step S53-2). In step S55-2, until the count value T of the timer reaches a predetermined count value T1, the control unit 32 displays a difference between the display image of each mark 28, 30 and the display image of each reference mark. Even if it is determined that there is (step S55-1: YES), the process may return to the process of step S54 without shifting to the process of operating the warning of step S57.

  In this way, by operating the timer mechanism and canceling the initial determination that there is a difference between the display image of each mark 28 and 30 and the display image of each reference mark in step S45 and step S55, noise or It is possible to prevent a warning from being actuated by an obstacle 50 or the like that has passed instantaneously. Thereby, it becomes possible to grasp | ascertain the obstruction 50 reliably.

  In addition, when the slide door 14 is fully opened, the timer mechanism is operated as described above even when the automatic door open / close switch 34 (for example, disposed in the center pillar) in the vehicle interior is operated from the outside of the vehicle interior to be fully closed. Thus, it is possible to start the fully-closing operation of the slide door 14 without determining that the operator is the obstacle 50 and after a time when the operator is absent.

  Further, in the above embodiment, after operating the automatic door opening / closing switch 34, a warning is issued when there is an obstacle 50 on the sliding locus of the entire sliding door 14, but it is stopped or warehousing. As described above, when the obstacle 50 is present on the slide locus of the entire slide door 14 before the operation of the automatic door open / close switch 34, a warning may be issued. Further, the warning in this case may be performed not only outside the passenger compartment but also inside the passenger compartment (for example, a driver).

  In addition, when it is determined that there is an obstacle 50 on the slide track of the entire sliding door 14 during semi-automatic and automatic parking operation, a warning is given to the driver, and semi-automatic and automatic parking operation is stopped, decelerated, and corrected. And so on.
