Application to be executed on the driver's seat side image.

  And in this modification 3, when the icons 35-40 as shown in FIG. 5 are displayed in the passenger seat side image in said step S2, the control part 9 drive | operates in step S3. The items being executed on the seat side are displayed in an identifiable manner. FIG. 5 shows a state where the FM icon 35 corresponding to the FM is displayed in an identifiable manner when the item acquired in step S1 is FM. Similarly, when icons 35 to 40 as shown in FIG. 5 are displayed in the driver side image in step S5, the control unit 9 is executed on the passenger seat side in step S6. The displayed item is identifiable. According to the navigation device 1 according to the third modification, the same effect as that of the first embodiment can be obtained.

<Modification 4 of Embodiment 1>
The target for displaying in steps S3 and S6 is not limited to a dedicated image (selected image) for selecting an application, as shown in FIGS. For example, as shown in FIG. 6, an image during application execution (here, an icon 31, 32 a, 33 a, 34 a to which each application can be executed in the same manner as the icons 31, 32, 33, 34). It may be an image during execution of a radio broadcast application. That is, the image of the application item may correspond to the tabs 31a to 34a.

  In FIG. 6, as an example of the image displayed in steps S3 and S6, the internal pattern of the tab of the item being executed on the driver's seat side (here, the audio tab 33a) and the tabs of the other items ( Here, the map tab 31a, the destination search tab 32a, and the setting tab 34a) are displayed so as to be different. In steps S3 and S6, it is only necessary to display the items of the application executed in the driver's seat side image and the other items so as to be distinguishable. It is not limited to what you do. For example, the information may be displayed so as to be identifiable using a difference in color (highlight) inside the tab, a difference in tab size, a difference in font of characters in the tab, or emphasis.

<Other Modifications of Embodiment 1>
When the number of icons (images of application items) is large, the control unit 9 slides the icons in accordance with operations such as flicks received by the operation unit 8, so that the driver side image and the passenger side You may make it switch and display an icon in an image. And in this structure, when the icon which the other party is performing is displayed in the driver's seat side image and the passenger's seat side image, the control part 9 does not switch immediately by a slide, but changes the said slide. You may make it stop once.

<Embodiment 2>
Hereinafter, the navigation apparatus 1 according to the second embodiment of the present invention will be described focusing on differences from the components described in the first embodiment. FIG. 7 is a flowchart showing the operation of the navigation device 1 according to the second embodiment. Hereinafter, the operation of the navigation device 1 according to the second embodiment will be described with reference to FIG. In addition, the block diagram which shows the structure of the navigation apparatus 1 which concerns on this Embodiment 2 is the same as that of FIG.

  First, in step S11, the control unit 9 determines whether or not the host vehicle is traveling based on the vehicle state information from the host vehicle. If it is determined that the vehicle is traveling, the process proceeds to step S12. If it is determined that the vehicle is not traveling, the process returns to step S11.

  Here, the following description will be made on the assumption that the destination search application has been executed on the driver's seat side before step S12. Specifically, when the operation unit 8 receives an operation for selecting the destination search icon 32 (FIG. 2) from the driver side, the control unit 9 displays the icons 41 to 46 shown in FIG. It is assumed that an address icon 41, a telephone number icon 42, a building name icon 43, a map icon 44, a zip code icon 45, and a home icon 46) for searching are displayed in the driver side image.

  In step S12, the control unit 9 performs an operation restriction that restricts (invalidates) an operation on a predetermined item in the driver seat side image from the driver seat side. In other words, the control unit 9 performs operation restriction on the driver's seat side according to the traveling of the host vehicle. Hereinafter, a predetermined item subject to operation restriction is referred to as “operation restriction item”.

  In step S12, the control unit 9 displays the operation restriction items and the other items in the driver side image so as to be distinguishable. 9 and 10 show an example of the driver's seat side image in step S12. Specifically, among the icons 41 to 46 shown in FIG. 8, icons other than the home icon 46 are operation restriction items. Examples that fall under are shown. In FIG. 9, icons corresponding to the operation restriction items are blurred and displayed, and in FIG. 10, a telop 51 indicating that the operation is prohibited during travel is superimposed on the icons corresponding to the operation restriction items. Yes. At this time, when the operation unit 8 receives an operation for the operation restriction item from the driver's seat side, the control unit 9 may cause the audio output unit 5 to output a warning sound.

  According to the configuration as described above, the driver can easily recognize that the home icon 46 can be operated but the other icons cannot be operated.

  So far, the driver side image and the driver side operation have been described. On the other hand, on the passenger seat side, the same display as the normal display is performed regardless of whether or not the operation restriction on the driver seat side is implemented, and the operation from the passenger seat side to the operation unit 8 is also effective. It has become. However, the normal display here includes the display described in the first embodiment (displaying the icon executed on the driver's seat side in an identifiable manner on the passenger side image). To do. Therefore, under the above assumption that the destination search application is executed on the driver side before step S12, the destination search icon is displayed when the image of FIG. 2 is displayed in the passenger side image. 32 is displayed in an identifiable manner.

  Next, in step S13, the control unit 9 accepts an operation for the icon (here, the destination search icon 32) displayed in an identifiable manner in the passenger seat side image from the passenger seat side by the operation unit 8. It is determined whether or not. If it is determined that the operation has not been received, the process proceeds to step S14. If it is determined that the operation has been received, the process proceeds to step S16.

  In step S14, the control unit 9 determines whether or not the host vehicle is traveling based on the vehicle state information from the host vehicle. If it is determined that the vehicle is traveling, the process returns to step S13. If it is determined that the vehicle is not traveling, the process proceeds to step S15.

  In step S15, the control unit 9 cancels the operation restriction performed from step S12, and the driver's seat side image is changed from the image shown in FIG. 9 or 10 to the image shown in FIG. Return to (Image). Thereafter, the operation shown in FIG.

  When the process proceeds from step S13 to step S16, as shown in FIG. 11, the control unit 9 displays a telop 52 for confirming whether or not to take over the operation on the driver's seat side in the passenger seat side image. In Step S16, when it is determined that the control unit 9 has accepted the operation for taking over from the passenger seat side at the operation unit 8 (the operation for selecting “Yes” in FIG. 11 has been accepted). The process proceeds to step S17. On the other hand, when it is determined in step S16 that the control unit 9 has not accepted the operation for taking over from the passenger seat side in the operation unit 8 (the operation for selecting “No” in FIG. 11 has been accepted). Advances to step S14 described above.

  In step S <b> 17, the control unit 9 displays the same image (here, the image of FIG. 8) as the driver seat side image as the passenger seat side image, and takes over the operation from the driver seat side to the passenger seat side. It should be noted that the transfer of the operation from the driver's seat side to the passenger's seat side means that the items selected by the operation from the driver's seat side and the set contents up to step S12 can be transferred to the passenger seat side. .

  In step S17, the control unit 9 displays the operation restriction items and the other items in the passenger side image so as to be distinguishable. FIG. 12 shows an example of the passenger side image in step S17. Specifically, the internal patterns (hatching of fine dots) of the icons 41 to 45 corresponding to the operation restriction items are indicated by the operation. It is displayed differently from the pattern (plain color) inside the home icon 46 not corresponding to the restriction item.

  According to such a configuration, the passenger can easily recognize that the icons 41 to 45 are operation restriction items. Thereby, for example, when a passenger performs an operation in response to an instruction from the driver, the contents of the instruction can be easily understood.

  In step S17, the operation restriction item and the other items may be displayed so as to be distinguishable, and the display is not limited to those that can be identified using the difference in the pattern inside the icon. For example, it may be displayed so as to be identifiable by using a difference in color inside the icon, a difference in font of characters in the icon, or emphasis.

  After step S17, in step S18, the control unit 9 determines whether or not the host vehicle is traveling based on the vehicle state information from the host vehicle. If it is determined that the vehicle is traveling, the process returns to step S18. If it is determined that the vehicle is not traveling, the process proceeds to step S19.

  In step S19, the control unit 9 displays the same image as the passenger seat side image as the driver seat side image, and takes over the operation from the passenger seat side to the driver seat side. Note that the operation from the passenger seat side to the driver seat side means that the items selected by the operation from the passenger seat side during step S17 to step S19 and the set contents are transferred to the driver side. It means that you can take over. Thereafter, for example, in the passenger seat side image, the image displayed as the passenger seat side image at the time of step S17 is displayed, and the items and settings selected by the operation from the passenger seat side until step S17 are set. The contents are restored to the passenger side. In step S19, the control unit 9 releases the operation restriction implemented from step S12. Thereafter, the operation shown in FIG.

  According to the navigation device 1 according to the second embodiment as described above, when the operation restriction on the driver's seat side is performed, the same image as the driver's seat side image is displayed as the passenger seat side image, and the driver's seat The operation can be taken over from the passenger side to the passenger seat side. Further, when canceling the operation restriction, it is possible to display the same image as the passenger seat side image as the driver seat side image and to take over the operation from the passenger seat side to the driver seat side. Therefore, even if the operation is restricted, the driver and the passenger can continue the operation by cooperating.

<Modification 1 of Embodiment 2>
There are cases where a plurality of driver-seat-side images are switched and displayed in accordance with an operation from the driver-seat side before the above-described operation restriction is performed (step S12). In such a case, when the control unit 9 takes over the operation from the driver seat side to the passenger seat side (step S17), all of the same images as the switched driver seat side images are switched in the order of switching. It may be displayed as a passenger seat side image.

  In the following, as a premise, the operation unit 8 performs an operation for returning from the audio image (FIG. 5) to the menu image (FIG. 2) and the destination search icon 32 (FIG. 2) until step S12 is performed. ) And an operation for selecting the address icon 41 (FIG. 8) are accepted in this order. In this case, the control unit 9 uses, as the driver's seat side image, an audio image (FIG. 5), a menu image (FIG. 2), a destination search method image (FIG. 8), and the address input shown in FIG. Images (images for displaying address input character buttons 47) are switched and displayed in this order.

  FIG. 14 is a diagram in which switchable images are connected by lines. In FIG. 14, the order of items displayed as a driver's seat image based on the above-described assumption is indicated by a solid arrow A.

  When switching as shown by the arrow A is performed, in step S17, the control unit 9 according to the first modification example displays an audio image (FIG. 5), a menu image (FIG. 2), a destination The search method image (FIG. 8) and the address input image (FIG. 13) are displayed in this order (that is, in the order of switching) as the passenger seat side image. According to such a configuration, the passenger confirms what operation has been performed on the driver's seat side before the operation is taken over from the driver's seat side to the passenger seat side (until the operation is restricted). can do.

  Note that the control unit 9 may display some of the same images as the plurality of driver-seat-side images, instead of displaying all of them. For example, as indicated by the broken-line arrow B in FIG. 14, the control unit 9 may display images only in the order from the upper hierarchy to the lower hierarchy. Further, for example, the control unit 9 may display only some images (for example, five images) that have been most recently switched as the passenger seat side images in the order of switching.

  As described above, it has been described that a plurality of images are switched and displayed when the operation is handed over from the driver seat side to the passenger seat side (step S17). A display similar to this may be performed when the operation is handed over from the passenger seat side to the driver seat side (step S19).

  That is, in response to the operation from the passenger seat side between the time when the operation is transferred from the driver seat side to the passenger seat side and the time when the operation is transferred from the passenger seat side to the driver seat side (between Step S17 and Step S19). In some cases, a plurality of passenger side images are displayed by switching. In such a case, when the control unit 9 takes over the operation from the passenger seat side to the driver seat side (step S19), some or all of the same images as the plurality of passenger seat side images that have been switched, You may display as a driver's seat side image in the order switched.

  According to such a configuration, the driver can perform any operation on the passenger seat side between the time when the operation is taken over from the passenger seat side to the driver seat side and the time when the operation is taken over from the driver seat side to the passenger seat side. It is possible to confirm whether the operation has been performed.

<Modification 2 of Embodiment 2>
In the period from when the operation is taken over from the passenger seat side to the driver seat side until the operation is taken over from the driver seat side to the passenger seat side (between steps S16 to S18), the operation restriction items are handled from the passenger seat side. It is assumed that the operation is accepted. Therefore, in this case, the control unit 9 may display the contents of the operation in the driver seat side image in real time.

  The content of the operation displayed in the driver's side image may be information that does not hinder driving. For example, up to five characters that have been input most recently by an operation from the passenger seat side, at a glance Simple characters that can be seen, or characters that are set in advance such as “Destination address is being entered on the passenger seat side” may be applied. Moreover, it may replace with the driver's seat side image of the display part 2, and the control part 9 may display the content of the above-mentioned operation on the instrument panel (not shown) with which the own vehicle was equipped.

  According to such a configuration, the driver can set the operation restriction item between the time when the driver takes over the operation from the driver side to the side of the passenger seat and the time when the driver takes over the operation from the passenger side to the driver side. It is possible to confirm what kind of operation is being performed on it.

<Modification 3 of Embodiment 2>
The controller 9 may perform step S16 without performing step S13 after performing step S12. That is, the control unit 9 may display the telop 52 shown in FIG. 11 in the passenger side image immediately after performing the operation restriction on the driver side. According to such a structure, since the operation for taking over can be simplified, it is possible to reduce the effort of the passenger.

  Moreover, the control part 9 may perform step S17, without performing step S13 and step S16, after performing step S12 according to the item of the application currently performed with the passenger side image. That is, the control unit 9 may forcibly take over the operation from the driver seat side to the passenger seat side after performing the operation restriction on the driver seat side. According to such a configuration, it is not necessary to perform an operation for taking over, so that it is possible to reduce the labor of the passenger. In addition, when a DVD is reproduced with a passenger side image or when an image for setting is displayed, it is possible to prevent the image from being taken over forcibly.

  It should be noted that the present invention can be freely combined with each other within the scope of the invention, and each embodiment can be appropriately modified or omitted.
