Since the key is displayed, the specific input operation by the driver can be more reliably excluded, and the operation by a person other than the driver can be received more reliably.

Hereinafter, a preferred embodiment of the vehicle information processing device of the present invention when applied to a navigation device will be described in detail with reference to FIGS. 1 to 5.
(1) Outline of Embodiment In the navigation device of the present embodiment, a driver's seat monitor (first display device) and a passenger's seat (rear seat) monitor (second display device) are arranged separately, and both monitors are arranged. The operation keys to be displayed are different depending on the state.

FIG. 1 shows an arrangement state of a driver seat monitor and a passenger seat monitor in the navigation device of the present invention.
As shown in FIG. 1, the driver's seat monitor 11a is disposed in the vicinity of the driver's seat, and the passenger's seat monitor 11b is disposed in front of the passenger seat away from the driver's seat or at a position on the window side from the front.
Whether or not the driver's seat monitor 11a is in the vicinity or away is determined by whether or not the driver can operate the key while performing the driving operation.

Instead of the passenger seat monitor 11b, or in addition to the passenger seat monitor 11b, a rear seat monitor operated by a passenger in the rear seat may be arranged. In the present specification, the term “passenger seat monitor 11b” includes a rear seat monitor.
The rear seat monitor is disposed, for example, on the rear surface of the rear driver seat, the rear surface of the passenger seat, between the driver seat and the passenger seat, on the ceiling (roof) portion behind the driver seat, and the like.

The driver's seat monitor 11a corresponds to the state of the vehicle (for example, whether the vehicle is running or stopped) and the currently displayed display screen (destination setting screen, current location display screen, route guidance screen, etc.). Among the operation keys that can be operated, the operation key for the prohibited travel operation that is predetermined as the specific input operation is not displayed as the operable operation key (non-display process).
The prohibited operation during traveling refers to an operation that requires a series of continuous operations or an operation that requires a next input operation by changing the screen in response to one input operation.
In addition, as a non-display process that does not display the operation key corresponding to the prohibited operation operation while driving as an operable operation key, for example, when the operation key is not recognized, the operation key is displayed but the input operation is not accepted. There are a case where a state is displayed (for example, a color indicating that input is impossible), a case where a menu for starting a specific input operation cannot be recognized, and the like.
The state where the operation key or menu cannot be recognized includes the case where the display itself is not performed and the case where the operation key or the menu is filled with a specific color (for example, blue) so that the contents of the key cannot be recognized.

  On the other hand, the driver's seat monitor 11b is not operated by the driver. Therefore, unlike the driver's seat monitor 11a, each display is performed regardless of whether the vehicle is in a traveling state or a prohibited operation during traveling. All operation keys corresponding to the screen are displayed.

(2) Details of Embodiment FIG. 2 shows a configuration of the navigation device.
As shown in FIG. 2, the navigation device includes a navigation control unit 10 that controls the entire navigation device.
The navigation control unit 10 includes a driver seat monitor (first display device) 11a, a passenger seat monitor (second display device) 11b, a speaker 12, a current position detection unit 13, a storage unit 14, and a stop state detection unit 15. Is connected.

  The navigation control unit 10 is configured by a computer system including a CPU, a ROM, a RAM, and the like (not shown). By executing various programs stored in the ROM or the storage unit 14 using the RAM as a predetermined work area, the navigation control unit 10 Various functions such as destination setting, route search, route guidance, provision of various information, and the like are realized, including operation key display processing in the embodiment.

The driver seat monitor 11a and the passenger seat monitor 11b are display devices on which various types of information are displayed. A liquid crystal display is used for the driver seat monitor 11a and the passenger seat monitor 11b. Alternatively, a CRT, a plasma display, or the like may be used.
On the driver's seat monitor 11a and the passenger's seat monitor 11b, a screen for setting a destination necessary for route guidance is displayed according to an image display process by the navigation control unit 10, and a current position during traveling is displayed together with a map. Further, the route on which the vehicle should travel is displayed in the route guidance.
The driver seat monitor 11a and the passenger seat monitor 11b also display operation keys that can be operated by the user in accordance with the contents of the display screen. For example, on a screen displaying a map around the current location, a destination setting key for selecting a destination setting, a key for changing the scale of the displayed map, a key for selecting an audio operation, etc. Various operation keys are displayed.

Note that these operation keys may be arranged as dedicated keys that are permanently installed on the outer frame of the driver's seat monitor 11a and the passenger's seat monitor 11b.
However, the operation keys corresponding to the specific input operation are not arranged on the driver's seat monitor 11a, but may be arranged on the passenger's seat monitor 11b.

The driver's seat monitor 11a and the passenger's seat monitor 11b have a touch panel disposed on the surface of the liquid crystal display, and the display portions corresponding to various operation keys displayed on the liquid crystal display are pressed (touched) to the corresponding portions. The corresponding operation key is selected.
Further, for example, in a predetermined operation for setting a destination, a point on the map corresponding to the pressed point is selected by pressing a point on the displayed map.

The speaker 12 is connected to a sound processor (not shown) and outputs various sounds under the control of the navigation control unit 10.
From the speaker 12, for example, voice for route guidance such as "This road is 300m ahead", operation guidance voice for various screen operation methods displayed on the driver seat monitor 11a and the passenger seat monitor 11b, etc. Is output.
Note that the speaker 12 may also be used as an audio speaker disposed in the vehicle.

The current position detection unit 13 detects the current position (for example, an absolute position based on latitude and longitude) of the vehicle on which the navigation device is mounted. The detected current position is used, for example, for matching with road data in route guidance, and is displayed as the current position of the vehicle on the map displayed on the driver seat monitor 11a and the passenger seat monitor 11b.
The current position detection unit 13 includes one or a plurality of GPS (Global Positioning System) that measures the position of the vehicle using an artificial satellite, a vehicle speed sensor, a gyro sensor, a direction sensor, a steering angle sensor, a distance sensor, and the like. ing.

The storage unit 14 includes a program storage unit 14a and a data storage unit 14b.
In addition to the operation key display program in this embodiment, the program storage unit 14a stores a destination setting program, a route search program, a route guidance program, and other various programs as various programs for performing route guidance.
The data storage unit 14b stores various data such as map data, road data, and a travel prohibition operation table used in the operation key display program as various data necessary for the navigation process of the storage unit 14.

The travel prohibition operation table stores an operation (identification data corresponding to the operation) that prohibits an input operation from the driver's seat monitor 11a during travel in the operation key display program of this embodiment.
Examples of operations for which reception during driving from the driver's seat monitor 11a is prohibited include destination setting (such as input of a telephone number when selecting items in order of a plurality of hierarchies such as address input), navigation guidance display method, and the like. There are setting changes.
On the other hand, operations that are not prohibited while driving and are not specified in the travel-prohibited operation table include, for example, switching scales, one-touch destination setting (such as returning to a registered home), etc. is there.

The stop state detection unit 15 detects a state for the navigation control unit 10 to determine whether or not the vehicle is in a stop state.
The stop state detection unit 15 in this embodiment includes a vehicle speed sensor, and the vehicle speed is supplied to the navigation control unit 10. The navigation control unit 10 determines that the navigation is stopped when the vehicle speed V = 0.
The navigation control unit 10 may determine that the vehicle is stopped when vehicle speed V> predetermined vehicle speed v1 (for example, 5 km / h).
Further, the stop state detection unit 15 may detect the shift lever position, or may detect whether the side brake is on or off and supply it to the navigation control unit 10. In this case, the navigation control unit 10 determines that the shift lever is in the stopped state when the shift lever position is the parking P position and the side brake is on.
Note that the vehicle speed sensor of the stop state detection unit 15 may also be used as the vehicle speed sensor of the current position detection unit 13.

Next, operation key display processing in such a navigation device will be described.
FIG. 3 is a flowchart showing the operation of the operation key display process.
The navigation control unit 10 monitors whether or not a predetermined situation change has occurred (step 10).
Here, the case where the predetermined situation being monitored is changed means that any of the input operations is performed, and the display screens of the driver seat monitor 11a and the passenger seat monitor 11b are changed according to the input operation. And when there is a state change between when the vehicle is stopped and when the vehicle is running. The determination of whether or not the vehicle is running is the same as the determination in step 14 described later.
It is determined that the situation has also changed when the switch of the navigation device is turned on.

The navigation controller 10 checks the display screen currently displayed on the driver seat monitor 11a and the passenger seat monitor 11b (step 11).
Here, the display screen to be confirmed is a display screen excluding operation keys.
In the present embodiment, the driver seat monitor 11a and the passenger seat monitor 11b are configured to display a screen having the same contents except for the operation keys.

The navigation control unit 10 determines the operation keys to be displayed corresponding to the confirmed display screen (step 12), and displays all the determined operation keys on the passenger seat monitor 11b (step 13).
In this embodiment, the determination of the operation key is defined in the processing program being executed, but an operation key display table is created in advance corresponding to each display screen and processing state, and stored in the data storage unit 14b. You may make it leave.

Next, the navigation control unit 10 determines whether or not the vehicle is traveling from the vehicle speed detected by the stop state detection unit 15 or not (step 14).
In this embodiment, the navigation control unit 10 determines whether the vehicle is traveling when the vehicle speed V> 0, and determines that the vehicle is stopped when the vehicle speed V = 0. .

In this embodiment, it is determined in step 14 whether or not the vehicle is stopped. However, it may be determined whether or not the vehicle speed V is greater than a predetermined value V1 (for example, 5 km / h).
That is, the process may be shifted to step 15 when the vehicle speed is V> V1, and may be shifted to step 16 when the vehicle speed is V ≦ V1.

  Further, the navigation control unit 10 determines whether or not the operation key corresponding to the display screen determined in step 12 includes an operation key for which an operation during driving by the driver is prohibited. It is determined whether it is stored in the running prohibition operation table 14b (step 15).

  In the operation key display processing flowchart shown in FIG. 3, it is determined whether or not there is a prohibited operation while traveling (step 15) after determining whether or not the vehicle is traveling (step 14). Or vice versa.

  When the vehicle is stopped (step 14; N) or / and when there is no prohibition operation during travel (step 15; N), the navigation control unit 10 uses all the operation keys determined in step 12 for the driver's seat. The data is displayed on the monitor 11a (step 16), and the process returns to the main routine.

  On the other hand, when the vehicle is traveling (step 14; Y) and there is a prohibited operation during traveling (step 15; Y), the navigation control unit 10 responds to the operation key of the corresponding prohibited operation during traveling. The non-display process is performed, other operation keys are displayed on the driver's seat monitor 11a (step 17), and the process returns to the main routine.

Next, an operation key non-display process for the prohibition operation during traveling will be described.
The operation key non-display process is a process for preventing the operation key for the prohibited operation while traveling from being displayed on the driver's seat monitor 11a as an operable operation key.
In the navigation control unit 10 of the present embodiment, as the non-display process, the operation keys for the prohibited operation during traveling are not displayed at all.
That is, out of all the operation keys displayed on the passenger seat monitor 11b, the operation key portion for the prohibition operation while traveling is not displayed, and the other operation keys are displayed in the same manner as the passenger seat monitor 11b.

The operation keys are displayed on the display screen (display screen confirmed in step 11) displayed on the driver seat monitor 11a and the passenger seat monitor 11b.
Therefore, the display screen confirmed in step 11 is displayed in the area of the operation key subjected to the non-display process on the driver's seat monitor 11a.

FIG. 4 illustrates a display screen of the passenger seat monitor 11b on which all the operation keys are displayed and the driver seat monitor 11a on which the operation keys for the prohibition operation during traveling are not displayed depending on the situation.
In the example of FIG. 4, a display screen in the middle of route guidance to the destination is illustrated, and the same display screen (other than operation keys) is displayed on both the driver seat monitor 11a and the passenger seat monitor 11b. A map 80 around the current position of the vehicle is displayed, and a searched traveling route 81 and a current position mark 82 representing the current position of the vehicle are displayed.

Then, on the passenger seat monitor 11b, all the operable keys are displayed on the outer periphery.
On the other hand, on the driver's seat monitor 11a, the area of the destination setting key corresponding to the prohibition operation during traveling is hidden, and a map is displayed in that area. Even if the driver presses (touches) the touch panel in the non-display area, the destination setting operation is not input.

Specifically, in the example of FIGS. 4A and 4B, since the vehicle is not running, all operation keys corresponding to the current display screen are displayed at the bottom of the screens of the monitors 11a and 11b. "Display change", "Point registration", and "Wide area" are displayed.
The "Detail" and "Wide Area" keys are used to change the scale of the displayed map. Touching "Detail" reduces the map scale and displays a detailed map. Touching "Wide Area" displays the map. The scale is increased and a wide area map is displayed.
The input operation using the “details” and “wide area” keys does not correspond to the prohibition operation during traveling.

The “display change” key is an operation key for changing the display method of the map, and the “point registration” key is an operation key for designating a point on the map and registering the point.
The operation keys “display change” and “point registration” correspond to the prohibition operation during traveling.

When the vehicle starts running in the state of the display screens of FIGS. 4A and 4B, the navigation control unit 10 determines that the situation has changed (step 10).
Then, as shown in FIG. 4C, the operation keys of the passenger seat monitor 11b are displayed as they are (all the operation keys corresponding to the current screen are displayed).
On the other hand, as shown in FIG. 4 (d), the driver's seat monitor 11a hides the operation keys “display change” and “location registration” corresponding to the operation prohibited operation among the displayed operation keys. To do.
In this way, since the operation keys “change display” and “spot registration” are not displayed at all on the driver's seat monitor 11a during driving, the driver does not recognize that these operations are possible. It is possible to effectively prevent the prohibition operation during traveling by the rider.

As shown in FIG. 4 (c), on the screen of the passenger seat monitor 11b, all operation keys are displayed regardless of whether or not the vehicle is traveling and whether or not the operation is prohibited during traveling. All operations are possible.
Therefore, for example, when the passenger in the passenger seat selects, for example, the operation key “change display”, various screens for changing the display of the map or the like are displayed on the passenger seat monitor 11b, and FIG. The screen on the way is displayed.

In FIG. 4 (e), when the “display change” key is touched from the passenger seat monitor 11b, a display change screen is displayed in another window, and the “2D / 3D / twin” key is selected on this display change screen ( 2), the 2D / 3D / twin selection screen is displayed in a separate window.
The currently active screen is the last selected 2D / 3D / twin selection screen, where the current map display method 2D display (shown in FIG. 4A) is darkly displayed. Yes.
On the other hand, the operation keys “detail”, “display change” and the like on the original map display screen, and the operation keys “2D / 3D / twin”, “VICS”, “? It is thinly displayed.

FIG. 4F shows a display screen of the driver seat monitor 11a corresponding to the display on the passenger seat monitor 11b (FIG. 4E).
As shown in FIG. 4 (f), the operation key “display change” selected from the passenger seat monitor 11b corresponds to a prohibited operation during traveling. Therefore, a series of display screens (displays) associated with the prohibited operation during traveling are displayed. The change screen, 2D / 3D / twin selection screen) itself is not displayed.
In this way, not only the operation keys but also a series of display screens associated with the prohibition operation during traveling are targets for the non-display process.
In addition, the operation keys “details” and “wide area” of the driver's seat monitor 11a are also lightly displayed as the inoperable keys in conjunction with the display on the passenger seat monitor 11b.

In the 2D / 3D / twin selection screen in FIG. 4E, when the passenger in the passenger seat selects, for example, the operation key “2D”, the screen is displayed as shown in FIGS. 4G and 4H except for the operation key. Is divided into left and right, and the display screen is changed to a map of two-dimensional display in different directions.
There are two types of map orientations displayed: north-up display in which north is always on the upper side of the screen, and heading-up display in which the traveling direction of the vehicle is always on the upper side of the screen.
The left screen is displayed in a map display (North Up Display) before the display is changed, and the right screen is displayed in the other map display (Head Up Display).

On the passenger seat monitor 11b, as shown in FIG. 4G, all of the operation keys “details”, “display change”, “point registration”, and “wide area” corresponding to the screen after the change are displayed. .
On the other hand, since the vehicle is running on the driver's seat monitor 11a, as shown in FIG. 4 (h), the operation keys “display change” and “point registration” corresponding to the running prohibited operation among all the operation keys are displayed. The non-display processing is performed, and the other operation keys “details” and “wide area” are displayed.

Thus, since the prohibition operation during traveling is not displayed on the driver's seat monitor 11a during driving of the vehicle, the prohibition operation during traveling from the driver's seat monitor 11a by the driver can be completely eliminated.
On the other hand, since all the operation keys corresponding to the display screen are displayed on the passenger seat monitor 11b regardless of the running state of the vehicle, the passenger in the passenger seat can surely perform all the operations.

As mentioned above, although the embodiment at the time of applying the information processing device for vehicles of the present invention to a navigation device was described, the present invention is not limited to the described embodiment, and various kinds are included in the range described in each claim. Deformation can be performed.
For example, in the embodiment described above, the vehicle information processing apparatus is applied to a navigation apparatus, but may be applied to a vehicle internet apparatus, an electronic mail apparatus, a videophone, a facsimile apparatus, and the like.
For example, when applied to an audio apparatus such as a radio reception apparatus, for example, a registration operation (frequency selection and registration processing, etc.) of a broadcasting station can be set as a prohibition operation during traveling.
Further, a specific operation such as a text input operation while connected to the vehicle internet can be set as a prohibited operation during traveling.

Further, in the embodiment described above, the case where the operation key for the prohibition operation while traveling on the driver's seat monitor 11a is hidden is described, but the corresponding operation key is not displayed at all. It is good.
As described above, the operation key non-display process is a process of preventing the operation key for the prohibited operation while traveling from being displayed on the driver seat monitor 11a as an operable operation key.
Therefore, a non-display process may be performed by displaying the operation key in a state where it can be recognized that the operation is not possible.
That is, the display of the operation key for the prohibition operation during traveling may be displayed separately from the display of the other operation keys that can be operated.
For example, the operation keys “detail” and “wide area” in FIG. 4F are displayed in a light color or in other colors. The operation keys in this case are naturally inoperable, and the input operation is not recognized even if the corresponding part is touched.

In the case of this non-display process, not only the operation keys but also a series of display screens accompanying the travel prohibition operation are displayed (for example, lightly displayed) in a state where it is possible to recognize the inoperability.
That is, in the screen of FIG. 4F, the display change screen and the 2D / 3D / twin selection screen (see FIG. 4E) are also displayed lightly.

In this way, since the prohibition operation key during traveling is displayed so that it can be recognized that it cannot be operated, the driver cannot perform the operation, but can recognize the operation key prohibited during traveling corresponding to the display screen.
For this reason, the driver can instruct the passenger in the passenger seat to perform the key operation necessary while checking the light-prohibited operation prohibition operation key that is displayed lightly instead of the operation by himself / herself.

Further, as another embodiment, similar to the case where the operation key is not displayed at all (the display itself is not performed), as another non-display process for making the operation key unrecognizable, for example, a specific color (for example, blue) In some cases, the key contents cannot be recognized by painting the operation keys.
In this case, the driver can recognize that there is an operation key that can be operated while the vehicle is stopped or the passenger on the passenger seat, but cannot specifically know the operation content of the operation key.

In the present embodiment described, the operation keys corresponding to the display screens in various states are determined (step 12). In the example of FIG. 4 showing one example, the operation keys are displayed on the display screen during route guidance. explained.
In this way, not only operation keys corresponding to various display screens during the execution of various functions of the navigation device, but also prohibition operations during traveling can be a target of non-display processing for screens in various initial states.

FIG. 5 shows operations that can be the target of the non-display process.
As shown in this figure, the display on the passenger's seat monitor 11b is not limited in any case and is all displayed and can be operated.
On the other hand, on the driver seat monitor 11a, as a first case, the destination setting menu and the navigation setting menu are displayed on the menu display screen, but the transition by the subsequent operation is not allowed.
In the first case, all the operation keys are displayed on the driver's seat monitor 11a in the same manner as the passenger's seat monitor 11b, but all the operation keys displayed on the driver's seat monitor 11a or the prohibited operation during traveling are displayed. Key input operations may not be accepted (reception is limited).
In the first case, when an operation key that is not subject to the input operation of the driver's seat monitor 11a is touched (pressed), it may be notified that the operation cannot be performed during traveling. As a notification method, a text to that effect is blinked on the monitor 11a, or a sound such as “cannot be operated while driving” is output from the speaker 12.

In the second case, on the menu screen, the menus such as purpose setting and navigation setting are completely hidden or displayed in a color indicating that input is impossible.
In the latter case, various menus are displayed but input is not possible. In this case, the destination setting menu and the navigation setting menu (operation keys) are displayed in a state in which input is impossible (operation is impossible), for example, a thin display.

As a third case, the screen itself may be erased (the entire screen is not displayed), or the entire screen may be filled with another color such as blue.
As a fourth case, the menu itself is not displayed or the transition to the menu screen is disabled.
In the third and fourth cases as well, the passenger seat monitor 11b can display the menu itself and make a transition to the menu screen.

Note that in the second, third, and fourth cases, the menu and operation keys are hidden, the screen itself is turned off, and the process of painting with other colors is performed by operating the driver's seat monitor 11a while driving. It may be executed when a key or an operation prohibition key during operation is operated.
Then, for a predetermined time after the operation is performed, for example, for 10 seconds, the menu and operation keys are hidden, the screen itself is turned off, or it is filled with another color, and then the original display screen (operation menu and operation You may make it return to the state where the key was displayed.

In the described embodiment, the case where the same screen is displayed on the driver's seat monitor 11a and the passenger's seat monitor 11b except for the operation keys has been described. However, the input operations of both the monitors 11a and 11b are made independent, The input operation may be reflected only on the input monitor.
Thereby, for example, a route guidance map or the like can be displayed on the driver seat monitor 11a, and an Internet screen, a television screen, or a DVD screen can be displayed on the passenger seat monitor 11b.

  Also in this case, the passenger's seat monitor 11b displays all the operation keys corresponding to each display screen, and all the key operations are valid, whereas the driver's seat monitor 11a is shown in FIG. The same processing as the operation key display processing (however, step 13 is unnecessary) is processed.

When the driver's seat monitor 11a and the passenger's seat monitor 11b are displayed on the screen independently as described above, the operation key “screen synchronization” may be displayed on the display screens of both the monitors 11a and 11b.
When this operation key “screen synchronization” is touched, the navigation control unit 10 executes screen synchronization processing so that the display screen of the touched side is the same as the display screen of the other monitor.
This makes it possible to synchronize the screens that have been displayed separately and independently with the same display screen.
In the screen synchronization processing, instead of synchronizing the entire screen, both the display screens of the driver's seat monitor 11a and the passenger's seat monitor 11b are divided into two, and both display screens are displayed on the respective divided screens. It may be.

In the embodiment described above, the operation keys displayed on the driver seat monitor 11a and the passenger seat monitor 11b are changed from the current display screen to the display screen as an example of determining the operation keys according to the processing state. The corresponding operation key was decided.
On the other hand, a predetermined display screen-operation key correspondence table corresponding to each display screen is stored, and an operation key to be displayed on the current display screen is determined by referring to this table. It may be.

As another example of determining the operation key according to the processing state, the operation key may be determined according to the stage of each process for realizing the function of the vehicle information processing apparatus.
For example, when the next process corresponding to the input of the operation key is defined in a hierarchical manner, for example, in the purpose setting process, an operation key corresponding to each process currently being executed may be determined.
In this way, all the operation keys corresponding to each process that can be performed to move to the next stage at the present time are determined.
