The display control unit 604 controls whether to display various image data (screen data) generated by the control unit 60 on the first display DP1 or the second display DP2, and displays a screen (for example, the first display DP1). 1 list screen) is output to the first display output unit 21 and a screen (for example, the second list screen) to be displayed on the second display DP2 is output to the second display output unit 22. In a preferred embodiment, when the second list screen is generated by the list screen generation unit 603, the display control unit 604 switches the screen displayed on the second display output unit 603 to the second list screen or displays an interrupt. Let
For example, the display control unit 604 outputs the first list screen generated by the list screen generation unit 603 to the first display output unit 21, and the first display output unit 21 displays the first list screen on the first display DP1. . Also, the display control unit 604 outputs the second list screen generated by the list screen generation unit 603 to the second display output unit 22, and the second display output unit 22 displays the second list screen on the second display DP2. .

  At this time, when the display control unit 604 outputs the second list screen to the second display output unit 22, the display control unit 604 restricts the display of a part of the operation command keys that have been displayed so far. It may be controlled to display a message indicating that all operations can be replaced with another switch (for example, the steering remote controller SW2) on at least one of the first display DP1 and the second display DP2. Further, it is also possible to guide that the alternative operation can be performed using the voice by the control unit 60. For example, a message indicating that the above-described alternative operation is possible can be displayed in the music name display field displayed on the second list screen.

Next, the list display control operation of the in-vehicle system according to the first embodiment configured as described above will be described with reference to FIG.
When a user performs a predetermined list display operation (for example, an operation such as destination search or content search) to display a list using the operation unit 20 (step S101), the NV function unit 30 or the AV function unit 31 operates. Information corresponding to the instruction is extracted from the data memory 40. Then, the item acquisition unit 601 acquires a plurality of information extracted by the NV function unit 30 or the AV function unit 31 as a list display item (step S103).
Subsequently, the determination unit 602 determines whether all the display items of the list acquired by the item acquisition unit 601 can be displayed in a predetermined area of one screen of the first display DP1 (step S105).

If the determination unit 602 determines that display is possible, the list screen generation unit 603 generates a first list screen to be displayed on the first display DP1 using the display items of the list acquired by the item acquisition unit 601. (Step S107).
Then, the display control unit 604 outputs the first list screen generated by the list screen generation unit 603 to the first display output unit 21, and the first display output unit 21 displays the first list screen on the first display DP1. (Step S109). At this time, on the second display DP2, the conventional normal audio screen (FIG. 2C) is still displayed.

  On the other hand, if the determination unit 602 determines that display is impossible, the list screen generation unit 603 uses the display items of the list acquired by the item acquisition unit 601 to display on the first display DP1. Is generated (step S111). Thereafter, the list screen generation unit 603 generates a second list screen to be displayed on the second display DP2 by using the display items of the list that could not be displayed on the first list screen (step S113).

  The display control unit 604 outputs the first list screen generated by the list screen generation unit 603 to the first display output unit 21 and outputs the second list screen to the second display output unit 22. Then, the first display output unit 21 displays the first list screen on the first display DP1, and the second display output unit 22 displays the normal audio screen that has been displayed on the second display DP2 (FIG. 2C). )) To display the second list screen on the second display DP2 (step S115).

A specific display example of the list screen will be described with reference to FIG.
During normal driving, the in-vehicle system displays a map image (FIG. 9A) around the vehicle position generated by the NV function unit 30 on the first display DP1, while the second display DP2 A normal audio screen (FIG. 9 (b)) on which information (music name), track up and track down operation command keys generated by the AV function unit 31 and the sound volume are arranged is displayed. Yes.

  In such a situation, for example, when the user sets a desired point as a destination, for example, by speaking a certain city name and performing a destination search (city name search) by voice input, the NV function unit 30 Extracts a city name that matches or is similar to the city name converted into character string data by the voice recognition function of the operation unit 20 from the map DB of the data memory 40. Then, the item acquisition unit 601 acquires 12 city names shown in FIG. 6A extracted by the NV function unit 30 as display items of the list. Subsequently, the determination unit 602 determines whether all acquired city names can be displayed on the first display DP1 or not. The determination unit 602 cannot display all acquired items on one screen because the number of items that can be displayed on the first display DP1 is six and the number of items acquired by the item acquisition unit 601 is twelve. And the result is provided to the list screen generation unit 603.

Since the provided judgment result cannot be displayed, the list screen generation unit 603 uses the top six (from “TORRANCE” to “LAWRENCE”) among the 12 city names shown in FIG. Then, the first list screen shown in FIG. 9C is generated. The list screen generation unit 603 further generates the second list screen shown in FIG. 9D using the next six items (from “TOLLHOUSE” to “DE LUZ”) that could not be displayed on the first list screen. .
When generating the second list screen, the list screen generating unit 603 does not use all or part of various command keys and music information shown in FIG. 9B for the list display of the second list screen. The region is arranged in a predetermined region AR4 such as a peripheral portion of the list display. The list screen generation unit 603 provides the generated first list screen and second list screen to the display control unit 604, and the display control unit 604 outputs the first list screen to the first display output unit 21, The list screen is output to the second display output unit 22.

Then, the first display output unit 21 displays the first list screen on the first display DP1, and the second display output unit 22 displays the normal audio screen displayed in FIG. 9B from FIG. 9D. The screen is switched to the second list screen and displayed on the second display DP2.
The user can look for the desired city name by looking at the first list screen displayed on the first display DP1 and the second list screen displayed on the second display DP2, and using the operation unit 20, Select the city name. When the destination is set, the NV function unit 30 searches for a route to that point, and displays a route map image on which the route shown in FIG. 9E is drawn on the first display DP1. At the same time, the AV function unit 30 displays the same normal audio screen (FIG. 9F) as in FIG. 9B on the second display.

  In this way, according to the in-vehicle system of the first embodiment, when displaying a plurality of information items as a list, it is determined whether or not all list items can be displayed on one display, and cannot be displayed. In this case, since the subsequent list items that could not be displayed on the first display are displayed on the other display, the multiple displays provided in the in-vehicle system are effectively used, and the user has to do the operation. Can be omitted.

  In the first embodiment described above, the display of the search result list of the city name search by voice recognition has been described as an example of the list display. However, the present invention is not limited to this, but the switch of the operation unit 20 is not an operation by voice recognition. (SW1 and SW2 in FIG. 2A), the touch panel on the surface of the first display DP1 or the second display DP2, and the like can be used. It can be applied not only to the search result list of city name search but also to the display of search result list of various destination searches such as facility name search, telephone number search, genre search, etc., and content search in audio function It can also be applied to the display of the search result list.

Further, the above-described list display control is performed only when a part of the operations is invalidated by the operation invalidating unit provided in the in-vehicle system according to the first embodiment. It is also possible to make it. The in-vehicle system according to Example 2 at this time will be described.
Since the vehicle-mounted system according to the second embodiment of the present invention has the same configuration as the vehicle-mounted system according to the first embodiment shown in FIG. 3, the same reference numerals are given and description thereof is omitted.
FIG. 10 shows a functional configuration block diagram related to the list display control method of the in-vehicle system of the second embodiment. As shown in the figure, a movement detection unit 621, an operation invalidation unit 622, an item acquisition unit 623, a determination unit 624, a list screen generation unit 625, and a display control unit 626 are configured. In the preferred mode, the function related to the list display control method as shown in FIG. 10 is implemented by the control unit 60 executing a program or an application.

  The movement detection unit 621 detects whether or not the vehicle position is moving based on the GPS signal from the GPS receiver 10 and the detection signal from the autonomous navigation sensor 11. Specifically, the movement detection unit 621 monitors these GPS signals and detection signals at predetermined intervals, and detects that the vehicle is moving when the signal (value) changes.

  When the movement invalidation unit 622 detects that the movement detection unit 621 is moving, the operation invalidation unit 622 invalidates a part of various operation instructions input from the operation unit 20 (performs operation restriction). Specifically, when the user performs an operation using the operation unit 20, the operation invalidation unit 622 determines whether or not the operation instruction corresponds to a predetermined limiting operation, and corresponds to the predetermined limiting operation. At that time, the operation instruction is not executed. At this time, a message indicating that the operation is invalid may be displayed on at least one of the first display DP1 and the second display DP2.

  For example, the operation invalidation unit 622 invalidates operations that require complicated operations such as destination setting operations, destination search operations, and content search operations, and does not invalidate simple operations such as track up operations and track down operations. . However, the operation invalidation unit 622 does not invalidate all of the various operations by voice input. In other words, the operation invalidation unit 622 does not invalidate (validate) the operation even when the user is moving when a destination search operation or a content search operation is input by voice input.

  In response to the user's list display operation, the item acquisition unit 623 causes the NV function unit 30 or the AV function unit 31 to extract information according to the list display operation, and the NV function unit 30 or the AV function unit 31 extracts the information. Information obtained as a list display item. However, when the list display operation is disabled by the operation invalidation unit 622 (that is, when the item acquisition unit 623 is moving and the list display operation is performed by a switch or touch panel operation), The process of acquiring the list display items is not executed. The list display item acquisition process performed by the item acquisition unit 623 is the same as that of the item information acquisition unit 602 of the first embodiment, and a description thereof will be omitted.

When the item acquisition unit 623 acquires the display items of the list when the operation invalidation unit 622 disables some operations, the determination unit 624 first displays all the display items of the acquired list. It is determined whether or not display is possible within a predetermined area of one screen of the display DP1. The determination of whether display is possible or not performed by the determination unit 624 is the same as that of the determination unit 602 in the first embodiment, and a description thereof will be omitted.
On the other hand, the determination unit 624 does not determine whether display is possible or not when the operation invalidation unit 622 does not invalidate some operations.

When the operation invalidation unit 622 invalidates a part of the operations, the list screen generation unit 625 receives the determination result as to whether display is possible or not from the determination unit 624. A list screen and / or a second list screen is generated. Since the process of generating the first list screen and / or the second list screen performed by the list screen generating unit 625 is the same as the list screen generating unit 603 in the first embodiment, the description thereof is omitted.
On the other hand, when the operation invalidation unit 622 does not invalidate some of the operations, the list screen generation unit 625 does not provide a determination result as to whether display is possible or not from the determination unit 624. Only the first list screen is generated using the provided list display items.

  The display control unit 626 performs the same processing as the display control unit 604 in the first embodiment, outputs the first list screen generated by the list screen generation unit 625 to the first display output unit 21, and displays the second list screen as the second list screen. Output to the display output unit 22.

Next, the list display control operation of the in-vehicle system according to the second embodiment configured as described above will be described with reference to FIG.
When the user performs a predetermined list display operation (for example, an operation such as destination search or content search) for displaying a list using the operation unit 20 (step S201), the movement detection unit 621 indicates that the vehicle is moving. It is detected whether or not there is (step S203). As a result of the detection, when it is detected that the user is moving, the control unit 60 checks whether the input method of the list display operation is a voice input or other methods (switch operation, touch panel operation, etc.). (Step S205).

  When determining that the list display operation is input by voice input in step S205, the control unit 60 executes the list display control from step S103 to step S115 of the first embodiment (step S207). On the other hand, when it is determined that the list display operation is input by a method other than the voice input, the operation invalidation unit 622 invalidates the list display operation (step S209). Therefore, the display screens of the first display DP1 and the second display DP2 do not change.

Returning to step S <b> 203, when the movement detection unit 621 detects that the movement is not being performed (stopped), the NV function unit 30 or the AV function unit 31 extracts information corresponding to the operation instruction from the data memory 40. To do. Then, the item acquisition unit 623 acquires a plurality of pieces of information extracted by the NV function unit 30 or the AV function unit 313 as list display items (step S211).
The list screen generation unit 625 generates a first list screen using the list display items acquired by the item acquisition unit 623. At this time, the list screen generation unit 625 does not generate the second list screen. That is, the control unit 60 does not perform the list display control of the first embodiment. The display control unit 626 outputs the first list screen generated by the list screen generation unit 625 to the first display output unit 21, and the first display output unit 21 displays the first list screen on the first display DP1 ( Step S213).

  In this way, according to the in-vehicle system of the second embodiment, when the operation is not restricted, that is, when it is not moving, it can be operated slowly, so that the conventional list display control is performed, while the operation restriction is performed. When the camera is moving, that is, when it is moving, it is necessary to reduce the number of operation procedures as much as possible. Therefore, it is possible to save the trouble of the user who is moving, performing list display control according to the present invention.

  In the second embodiment described above, it is detected that the movement is being detected by the movement detection unit 621, the operation using the switches and the touch panel is disabled by the operation invalidation unit 622, and the list display operation by voice input is performed. In the above example, the list display control is executed when the movement detection unit 621 is executed. However, when the movement detection unit 621 is simply moving, the list display control may be executed.

The present invention can also be applied to list display in functions other than the navigation function executed by the NV function unit 30 and the audio function executed by the AV function unit 31 described in the first and second embodiments. For example, a broadcast reception function unit for receiving broadcast waves such as television and radio is connected to the communication bus 100, and a list display of channel presets (frequency presets) used for the broadcast reception function of this broadcast reception function unit (FIG. )) And list display of receivable stations list, etc. It is also possible to connect a telephone communication function unit to the communication bus 100 and display a list of a telephone directory list or a list of shortcut dials (FIG. 12B) used for the telephone communication function of the telephone communication function unit. . These channel presets, receivable station information, telephone directory information and shortcut dial information may be stored in the data memory 40 or in a memory provided in each function unit.
In addition, a voice recognition command list that can be recognized by the voice recognition function of the in-vehicle system (FIG. 12C), a list of all functions that the in-vehicle system can provide, and an audio source list of the in-vehicle system ( The present invention can be applied to all items displayed in a list, such as FIG.

  Furthermore, although Example 1 and Example 2 which were mentioned above demonstrated as an example the vehicle-mounted system provided with two displays, it is applicable also to the vehicle-mounted system provided with three or more displays. For example, in the case of three, if not all list items can be displayed on the first display for normal list display, the subsequent list items are displayed on the second display. Further, if all list items are not displayed even if they are displayed on the second display, list items that could not be displayed even if the second display is used on the third display are displayed. . By doing in this way, all the displays with which the vehicle was equipped can be used effectively. However, display control is not performed for a display that cannot be seen by the driver.

  In the first and second embodiments described above, the first display DP1 is mounted above the second display DP2. However, for example, the second display DP2 is mounted above the first display DP1. In such a case, the first list screen can be displayed on the second display DP2, and the second list screen can be displayed on the first display DP1. By doing so, the list is displayed from the top to the bottom, so that the user can easily confirm. In addition, when the first display DP1 and the second display are not attached to the top and bottom but to the left and right, the two displays are compared and a list is displayed from either the left or right direction. You can also do it. Furthermore, the first or second display may be detachable.

  The preferred embodiment of the present invention has been described in detail above, but the present invention is not limited to the specific embodiment, and various modifications can be made within the scope of the present invention described in the claims. Deformation / change is possible.
