  The first display screen 8 and the second display screen 9 are displayed on the same display unit 7, but an operation icon corresponding to the passenger seat and an operation icon corresponding to the driver seat are displayed. Since the displayed area is physically separated on the display unit 7, it can be determined by the operation of the icon whether the assistant or the driver has performed the operation.

  Next, the control unit 200 determines whether or not the destination setting is possible (S3).

  Here, the situation where the driver can set the destination is only when the vehicle is stopped, and the situation where the assistant can set the destination is other than when the vehicle is traveling at high speed (less than 80 km / h). Therefore, the control unit 200 acquires vehicle speed information of the vehicle on which the display device 100 is mounted from the vehicle speed detection unit 240, and determines whether or not the destination can be set together with the subject of the operation determined in step 1. I do. For example, when the destination setting operation is performed from the driver's seat side even though the vehicle is traveling at high speed, a warning display (S20) is displayed to the effect that the destination setting cannot be performed at this time. Return to step 1.

  If it is determined in step 3 that the destination can be set, the control unit 200 changes the display screen of the display unit 7 for destination setting (S4).

In FIG. 17B, a display for confirming the reflection of the setting is displayed in the area 346 of the second display screen 9 on the driver's seat side, and a confirmation icon is shown in the area 344. If there is no problem, the “OK” icon is pressed. If there is a problem, the “reset” icon is pressed. If the “reset” icon is pressed, the process returns to step S5 and the destination is set again.

  That is, the example of FIG. 17 is configured so that the reflected setting can be confirmed only on the driver's seat side. When the setting is reflected, there is a possibility that the route on the route guidance screen may be changed. Therefore, the setting can be reflected only on the driver side.

  Next, the control unit 200 changes the destination (S10), searches for a new route (S11), displays the new route (S12), and ends a series of procedures.

  According to such a procedure, based on the subject who first operated the destination setting operation button, it is an optimal procedure for a display device that can observe different display contents according to the viewing direction on one display screen, It is now possible to check destination settings, check destination settings, and reflect destination settings.

  In the flow shown in FIG. 10, in step 2, it is determined whether the subject who has started the destination setting operation is a driver or an assistant according to an operation input from the touch panel 124 of the display unit 7. . However, the rear seat may be set so that the destination setting operation can be performed by a remote control (not shown) for the rear seat. That is, it may be set so that the destination setting operation can be performed from all seats.

  In the flow of FIG. 10, when the destination setting operation is started from the passenger seat side in Step 2, the destination setting screen is displayed only on the first display screen 8 on the passenger seat side. (See FIGS. 11 and 12). However, if the vehicle is stopped after the destination setting operation from the passenger seat side is started, the same destination setting screen (as in the passenger seat side) is also displayed on the second display screen 9 on the driver seat side. For example, it may be set to display (see FIG. 12A). With such a setting, it is possible to confirm the setting with both.

  In the flow shown in FIG. 10, in step 3, the destination setting operation from the passenger seat side is set so as to be permitted only at times other than during high-speed driving. However, the destination setting operation from other than the driver's seat side may be set so that it can always be performed. In addition, the destination setting operation from other than the driver's seat side may be set so that it can be performed only when the vehicle is stopped, like the driver's seat side. Further, the destination setting operation from the side other than the driver's seat side may be set so that it can be performed when it is determined that the congestion distance is sufficiently long (for example, 1 km or more) on the guidance route of the navigation device 206 (note that it is sufficient It is preferable that the user can set the traffic distance considered to be long). Furthermore, the destination setting operation from other than the driver's seat side may be set so that it can be performed only when the driver's side permits. Further, the destination setting operation from the side other than the driver's seat side continues on the guidance route of the navigation device 206 for a predetermined distance (for example, 5 km or more) on the road (no instructions for left turn, right turn, oblique line change, etc.). It may be set so that it can be performed in some cases (it is preferable that the user can set the predetermined distance). Further, the destination setting operation from other than the driver's seat may be set so that it can be performed when the signal is red by receiving the signal information.

  In the flow shown in FIG. 10, in step 4, during the destination setting from the passenger seat side, the destination setting operation from the driver seat side is prohibited, and during the destination setting from the driver seat side, from the passenger seat. Destination setting operation is prohibited. However, the destination setting operation may be performed at the same time. For example, the destination setting operation started on the driver's seat side may be taken over on the passenger seat side so that the destination setting can be completed.

  In the flow shown in FIG. 10, the display device 100 is configured to perform a destination setting operation by pressing an icon on the touch panel 124. However, the setting operation may be performed using a remote controller (not shown) for setting the destination, a dedicated display unit or a dedicated operation button provided separately from the main body of the display device 100. .

  In the flow shown in FIG. 10, the setting confirmation in Step 7 is performed on both the passenger seat side and the driver seat side. However, the setting confirmation may be performed so that only the side where the destination setting operation is started performs. For example, when the destination setting operation is started on the passenger seat side, the setting may be set so that the setting confirmation only needs to be performed on the passenger seat side.

  In the flow shown in FIG. 10, in step 8, the setting is confirmed to be reflected in step 9 only when the predetermined setting reflection is possible (except during high-speed traveling). However, the setting may be reflected immediately after the confirmation of the destination setting (S7). Further, after confirming the setting of the destination (S7), it may be set so that the setting is automatically reflected during straight running. Further, after confirming the destination setting (S7), the setting may be automatically reflected when waiting for a signal. Further, the setting reflection possible state may be configured to be selectable by the user.

  In the flow shown in FIG. 10, in step 8, by confirming the setting reflection, the setting reflection possible state is displayed (FIG. 16 or 17). However, it may be configured to notify that the setting can be reflected without special display by the color or blinking of the LED. Further, it may be configured to notify the user that the setting can be reflected by voice or an alarm without performing a special display.

  In the flow shown in FIG. 10, the setting reflection is confirmed only at the driver seat side in Step 9. However, it may be set so that it can be performed on either the passenger seat side or the driver seat side, or both. Also, the reflection of the setting may be confirmed from a rear seat other than the passenger seat and the driver seat using a predetermined remote controller or the like. Further, the reflection of the setting may be automatically performed when passing through the ETC-compatible toll gate based on the information from the ETC on-board unit 224.

  In the flow shown in FIG. 10, when the destination setting operation is performed on the passenger seat side, the route guidance screen is displayed on the second display screen 9 on the driver seat side as before ( (Refer FIG.12 (b)). However, in order to reduce the CPU load or the like of the control unit 200 of the display device 100, on the second display screen 9 on the driver's seat side, only the current vehicle position 304 is moved and the background map is not updated. It may be set to. Further, in order not to update the background map, the background map may be changed to a wide area map.

  In the flow of FIG. 10, the case where the destination is set using the display unit 7 (see FIG. 2) set on the dashboard has been described. However, the destination may be set using the rear display unit 223. Specifically, the display unit 7 displays the first display screen 8 and the second display screen 9 as shown in FIGS. 11A and 11B, and the rear display unit 223 displays the destination setting. A screen (for example, FIG. 12A) may be displayed, and a destination may be set using a touch panel for the rear display unit 223, a remote control, an operation button, or the like.
