  Here, an example of the display part movement process which the control part 6 performs is demonstrated based on the flowchart of FIG. In addition, it can be set as a display control program by comprising this flowchart as a computer program which the control part 6 performs.

  The control part 6 starts a display part movement process when a vehicle starts operation | movement, and determines whether a vehicle is a manual driving state (step S1). When the vehicle is in the manual operation state (Y in Step S1), the control unit 6 controls the moving unit 105 to move the center multimedia display 102 to the first position (Step S2). Following step S2, the control unit 6 determines whether or not the vehicle is in an automatic driving state (step S3). If the vehicle is not in the manual operation state (N in step S1), the control unit 6 proceeds to step S3.

  When the vehicle is in an automatic driving state (Y in Step S3), the control unit 6 determines whether or not content information has been selected (Step S4). When the content information is selected (Y in step S4), the control unit 6 controls the moving unit 105 to move the center multimedia display 102 to the second position (step S5), and returns to step S1. When content information is not selected (N in step S4), the control unit 6 returns to step S3. If the vehicle is not in the automatic driving state (N in step S3), the control unit 6 returns to step S1.

  With the above configuration, the position of the center multimedia display 102 is moved according to the driving state of the vehicle to move it to the second position where the driver can easily see in the automatic driving state, and in the manual driving state, the driver. Can be moved to the first position where it is difficult to obstruct when visually recognizing the outside of the vehicle. That is, the content information can be displayed at an appropriate position. At this time, it is not necessary to provide the display unit for the automatic operation state and the display unit for the manual operation state independently, and the number of display units can be reduced.

  When the vehicle is in an automatic driving state, it is possible to improve performance by moving the position of the center multimedia display 102 after content information is selected. When content information is not displayed in the automatic driving state, the center multimedia display 102 does not move to the second position, and the driver can easily see the outside of the vehicle. For example, the manual multimedia operation can be quickly performed according to the situation around the vehicle. Can be switched.

  When the center multimedia display 102 is adjacent to the driver display 101 in the horizontal direction at the second position, the driver can easily view the operation information while viewing the content information in the automatic driving state. Therefore, for example, it becomes easier for the driver to make a determination to switch to manual driving according to the operation information.

  When the center multimedia display 102 is adjacent to the windshield light 103b on the driver's line of sight in the second position, the driver can easily view the windshield light 103b while viewing the content information in the automatic driving state. . This makes it easier for the driver to notice a warning or the like by the windshield light 103b.

  In addition, this invention is not limited to the said Example, The other deformation | transformation etc. which can achieve the objective of this invention are included in this invention.

  For example, in the above-described embodiment, when the vehicle is in an automatic driving state, the center multimedia display 102 is adjacent to the driver display 101 in the horizontal direction and on the lower side of the windshield light 103b on the line of sight of the driver D. Although it moved to the 2nd position adjacent, it may be moved to other positions. That is, as shown in FIG. 6 as a modified example, the center multimedia display 102 may be moved to a position corresponding to the reclining angle of the driver's seat SH in the automatic driving state.

  In the example illustrated in FIG. 6, the driver seat SH is provided with an angle acquisition unit 106 that acquires a reclining angle of the seat (an inclination angle of the backrest). The angle acquisition unit 106 acquires the reclining angle by actually measuring the inclination angle of the backrest. Note that a drive unit may be provided in the driver seat SH so that the reclining angle is automatically changed according to the driving state of the vehicle. In this case, the angle acquisition unit is transmitted from the control unit 6 to the drive unit. The reclining angle may be acquired on the basis of the signal, or may not be provided in the driver seat SH.

  In the automatic driving state, since the backrest of the driver's seat SH falls down and the reclining angle can be made almost horizontal, the center multimedia display 102 is moved to a position corresponding to the reclining angle of the driver's seat SH. Thereby, it is possible to make the center multimedia display 102 visible to the passenger. At this time, depending on the reclining angle, the center multimedia display 102 may be adjacent to the driver display 101 in the horizontal direction as in the second position, or may be adjacent to the windshield light on the line of sight. The multimedia display 102 may be separated from the driver display 101 and the windshield light. Further, as in the example shown in the figure, the center multimedia display 102 may be moved to a position overlapping with the windshield W. Further, the reclining angle of the driver's seat SH may be adjusted by a driving unit (not shown) so that the driver D can easily see the center multimedia display 102 according to the position of the center multimedia display 102.

  In the above embodiment, the position of the center multimedia display 102 is moved after the content information is selected when the vehicle is in an automatic driving state. However, the center multimedia display 102 is moved at an appropriate timing. The center multimedia display 102 may be moved immediately after the automatic operation state is detected.

  In the above embodiment, the moving unit 105 moves the center multimedia display 102 as the content display unit along the vertical direction. However, the moving unit 105 may move it in the horizontal direction. For example, in the manual driving state, the content display unit is moved to the front of the passenger seat, and in the automatic driving state, the content display unit is moved to the front of the driver seat or in front of the intermediate position between the driver seat and the passenger seat. Good. When moving in this way, even if the content information is displayed on the content display unit in the manual driving state, it is difficult for the driver to enter the field of view and to prevent the driving.

  In addition, the best configuration, method and the like for carrying out the present invention have been disclosed in the above description, but the present invention is not limited to this. That is, the present invention has been illustrated and described primarily with respect to particular embodiments, but is not limited to the embodiments described above without departing from the scope and spirit of the present invention.
