The illumination controller 80 controls lighting of the lamps E1 to E8 based on input signals from the door drive mechanism controller 85 and the detectors 81 to 84.

  An example of the control of the lighting system configured as described above will be described with reference to the flowchart of FIG. This control example is an example of control performed by the illumination control unit 80 when the occupant opens the slide door manually and gets on.

  As shown in FIG. 12, when the door unlocking operation from the outside of the vehicle is detected by the door operation detector 83 in step # 1, the control in step # 2 and subsequent steps is performed. The unlocking operation from outside the vehicle here includes an unlocking operation by the keyless terminal 71 and an unlocking operation performed by inserting a key into a key hole of a door (for example, a door of a driver's seat).

  In Step # 2, illumination of the courtesy lamp E1 and the outer handle lamp E2 is started, and illumination of the console downlight lamp E6 and the room lamp E7 is prohibited. When this processing is performed, the visibility of the feet of the occupant who gets on the vehicle is improved by the illumination of the courtesy lamp E1, and the visibility of the outer handle is improved by the illumination of the outer handle lamp E2. Further, since the illumination of the console downlight lamp E6 and the room lamp E7 is prohibited, the upper body of the occupant can be reliably prevented from being illuminated, and the occupant's privacy can be effectively protected.

  Next, in step # 3, it is determined whether the operation of the outer handle 23 of the slide door 20 is detected by the door operation detection unit 83 within a predetermined time. This process is performed to determine whether or not an occupant gets on the second seat 12 or the rear seat 13 after unlocking the door. When the operation of the outer handle 23 is detected in step # 3, it is determined that an occupant gets on the second seat 12 or the rear seat 13, and the process proceeds to step # 4. On the other hand, if the operation of the outer handle 23 is not detected within the predetermined time in step # 3, it is determined that no occupant is on the second seat 12 or the rear seat 13, and the process proceeds to step # 13. In Step # 13, the courtesy lamp E1 and the outer handle lamp E2 are turned off, and the illumination prohibition of the console downlight lamp E6 and the room lamp E7 is released, and the control returns to the normal control.

  In step # 4, illumination of the foot lamp E3 is started. In step # 4, the visibility of the foot region S3 of the second seat 12 is improved by the illumination of the foot lamp E3.

  In the subsequent step # 5, illumination of the intermediate pillar lamp E4, the seat downlight lamp E5, and the inner handle lamp E8 is started. In step # 5, the visibility of the intermediate pillar 6 constituting a part of the outline of the entrance / exit Hs is improved by the illumination of the intermediate pillar lamp E4, and the seating surface area of the second seat 12 is illuminated by the illumination of the seat downlight lamp E5. The visibility of S5 is improved, and the visibility of the inner handle 25 is improved by the illumination of the inner handle lamp E8.

  As described above, in Step # 2 to Step # 5, the lights of the courtesy lamp E1, the outer handle lamp E2, the foot lamp E3, the intermediate pillar lamp E4, the seat downlight lamp E5, and the inner handle lamp E8 are adjusted in accordance with the riding operation. Since it starts in turn, you can effectively produce a feeling of welcome. Moreover, since the visibility of each part improves by illumination of these lamps E1-E5, E8, the convenience at the time of boarding is improved. Further, in steps # 2 to # 5, the console downlight lamp E6 and the room lamp E7 are prohibited from being illuminated, so that the upper body of the occupant is not illuminated when riding and the occupant's privacy is effectively protected. Can do.

  Next, in step # 6, it is determined whether or not the completion of the operation for the occupant to close the slide door 20 is detected by the door open / close state detection unit 82 within a predetermined time. This process is performed to determine whether or not the occupant's boarding operation has been completed. In step # 6, when the completion of the closing operation of the slide door 20 is detected, it is determined that the passenger's boarding operation is completed, and the process proceeds to step # 7. On the other hand, if the completion of the closing operation of the slide door 20 is not detected within a predetermined time in step # 6, it is determined that the occupant's boarding operation is not completed, and in step # 14, the courtesy lamp E1, The outer handle lamp E2, the foot lamp E3, the intermediate pillar lamp E4, the seat downlight lamp E5 and the inner handle lamp E8 are controlled to blink, and the control returns to the normal control. The blinking of these lamps E1 to E5 and E8 has an effect of notifying the passenger or a surrounding third party that the boarding operation is not completed. That is, by flashing the lamps E1 to E5 and E8, the passenger is informed that the door is a half-door (the slide door 20 is not completely closed) or that the riding operation cannot be completed due to an emergency situation. Can be notified to any third party. The blinking of these lamps E1 to E5 and E8 is eliminated when the slide door 20 is completely closed.

  In the subsequent step # 7 to step # 11, the lamps E1 to E5 and E8 lit in step # 2 to step # 5 are turned off in the same order as the lighting order. Specifically, the lamp is turned off in the courtesy lamp E1 (step # 7), the outer handle lamp E2 (step # 8), the foot lamp E3 (step # 9), the intermediate pillar lamp E4 (step # 10), and the seat downlight. The lamp E5 and the inner handle lamp E8 (step # 11) are performed in this order. In this way, by turning off the lamps E1 to E5 and E8 in the same order as the lighting, it is possible to enhance the production effect that creates a feeling of welcome. The lamps E1 to E5 and E8 are preferably turned off afterglow, thereby further enhancing the feeling of welcome.

  Finally, in step # 12, the console downlight lamp E6 is turned on, the illumination prohibition of the room lamp E7 is released, and the normal control is resumed. In this way, by turning on the console downlight lamp E6 in step # 12 when the boarding is completed, the hand of the passenger seated on the second seat 12 can be illuminated in a relatively safe state. Further, since the illumination prohibition of the room lamp E7 is released, the interior of the vehicle interior can be illuminated over a wide range by lighting the room lamp E7 as necessary in normal control.
