It has a function as a device.
[0037]
[Search and display of surrounding information]
Next, the search and display processing of the peripheral information will be described with reference to the flowchart of FIG. First, a destination and a route are set as described above (step 301). Then, the user sets parameters serving as search conditions for the peripheral information in advance (step 302). For example, the genre B and the range (distance from the route) are set as Am as facilities to be searched. At this time, for example, as shown in FIG. 4, the map is displayed on the display device 9 in a state where the traveling direction on the current route is directed upward with the current position of the vehicle calculated by the current position calculation unit 41 as the center. Is displayed, and the route in the map is displayed in a special color such as red.
[0038]
In such a state, when the user touches any place on the input device 10, this is detected by the touch detection unit 8a (Step 303). Then, based on the search conditions set in the search condition setting unit 47, the peripheral information search unit 46 uses the current position calculated by the current position calculation unit 41 from the database recorded on the CD-ROM or DVD-ROM. With this relation, information on nearby facilities that match the search conditions is searched and extracted in the order of proximity to the current position (step 304). At this time, the name, position information, and the like of each search target are recorded in the temporary storage medium control device 5 (step 305).
[0039]
Then, the button display generation unit 48 generates an image for button display based on the search result and sends it to the user interface control device 8, and accordingly, the button display control unit 8c transmits the peripheral information to the display device 9 in accordance with the image. Buttons as items are displayed (step 306). In this display mode, instead of switching to a screen different from the map screen of the display device 9, for example, as shown in FIG. 5, buttons are displayed so as to overlap the already displayed map screen. In addition, the image generated and displayed here shows the left-right positional relationship between the route and each facility and the anteroposterior relationship of each facility in the travel direction in a state where the traveling direction of the route is displayed on the map with the current position as the center. It is displayed as a caption in the form of a button while keeping it.
[0040]
Further, the position and number of items to be displayed are simply displayed according to the relative positions and numbers of the individual switches 10a in the input device 10. Although FIG. 5 shows an example in which six search results are displayed, when the number of search results is larger than that (for example, in the case of twenty, this condition can be set freely in advance). ), All are stored in the temporary storage medium control device 5 as described above.
[0041]
More specifically, the search for the peripheral information and the button display are performed according to the following guidelines. That is, for example, when the preset distance is 10 m, a range of 10 m from the road along the path in the traveling direction from the current position (for example, if the distance is 10 m, it is almost in contact with the road) ) As the search target.
[0042]
Then, a genre set in advance (for example, a genre including a search area set by the user, such as a genre item such as a store, a tourist attraction, or a group of items set in advance, from specific items such as convenience stores and gas stations). If there is an item corresponding to, the right and left sides are classified with respect to the traveling direction of the route, and the contents are displayed as buttons according to the items as shown in FIG. In this case, the right item 1 and the left item 1 indicate that the search object is closest to the traveling direction, and the right item 2 and the left item 2 are the next nearest objects to the traveling direction. Indicates that the object is a search target.
[0043]
When the switch 10a corresponding to any of these buttons is pressed (step 307), the direction of the current position is stored in the temporary storage medium control device 5 (step 308), and the map of the position where the information exists is stored. The information or information related thereto is displayed (step 309). In order to return to the original button display, selection of a return button by the input device 10 is performed (step 310). When the vehicle travels along the set route (step 311), the current position is changed, and the information assigned to each button is updated by re-searching the database in accordance with the change. (Step 312).
[0044]
Furthermore, the button display includes an up / down scroll button and a button for returning to the current position in the center. When the switch 10a corresponding to the arrow button in the traveling direction among the scroll buttons is pressed, a map is displayed when the current position of the vehicle virtually advances according to the set route. When the switch 10a corresponding to the button for returning to the current position is pressed, the map displayed on the screen is returned to a map centered on the current position.
[0045]
[Update processing associated with actual movement of vehicle]
Next, the details of the display processing when the current position moves with the movement of the vehicle will be described with reference to the flowchart of FIG. That is, the result of the search for the peripheral information as described above is stored in the temporary storage medium control device 5 (step 701). When the vehicle travels along the route and the current position moves, the comparison processing unit 49 compares the current position with the position information of the search result stored in the temporary storage medium control device 5, This is performed at intervals of a predetermined time t2 (steps 702 and 703).
[0046]
Then, of the information of the search result displayed on the current screen, for example, one of the right item 1 and the left item 1 is behind the current position on the set route (step 704), if the vehicle has not advanced beyond the range of the search result stored in the temporary storage medium control device 5 (step 705), the update processing unit 50 sends the button display generation unit 48 Then, the button display control unit 8c deletes the changed item and generates an image to which the next-ranked item stored in the temporary storage medium control device 5 is added, based on the generated image. Button display is performed again on the screen (step 707). When the vehicle advances and the search results stored in the temporary storage medium control device 5 become insufficient (step 705), the contents stored in the temporary storage medium control device 5 are deleted, and the surroundings are deleted. The information search unit 46 searches again using the current position (step 706), and the search result is displayed as a button (step 707).
[0047]
As shown in step 313 in the flowchart of FIG. 3, when it is detected that the user has released the hand from the switch 10a, the button display control unit 8c turns off the button display on the display device 9, so that the map information is deleted. You can see all. If a display end instruction has been input (step 314), the process ends.
[0048]
[Update processing accompanying scroll display]
By performing the scroll display of the map, the update processing of the button display is performed even when the position of the vehicle virtually moves. That is, as described above, the button display includes the up and down scroll buttons. When the switch 10a corresponding to the arrow button in the traveling direction among the scroll buttons is pressed, the current position of the vehicle virtually advances according to the set route, and the database is again adjusted to match the virtual current position. The prosecution is performed and the button display is updated. When the switch 10a corresponding to the arrow button opposite to the traveling direction is pressed, the current position of the vehicle virtually returns according to the set route, and the database is searched again according to the virtual current position. The button display is updated.
[0049]
An example of the update process accompanying such a scroll display will be described with reference to the flowchart in FIG. That is, as described above, the result of the search for the peripheral information is stored in the temporary storage medium control device 5 (step 801). In this state, scroll display is performed by pressing the switch 10a corresponding to the scroll button. The scroll display is performed such that the center point of the screen is always on the route with the center position of the screen as the reference point. When the scroll button on the upper side of the screen is operated, the scroll is performed toward the destination of the route, and when the scroll button on the lower side of the screen is operated, the scroll is performed on the route. Scrolled along the direction of returning from the direction of the destination.
[0050]
The scroll amount at this time depends on the scale of the map displayed on the screen and the time when the switch 10a is pressed. For example, if the actual distance in the vertical direction of the map displayed on the screen at that time is L (m), L / n (m) is changed within a predetermined time (t0 second) by the switch 10a. This is the amount of screen scrolling when pressed once (steps 802 and 803). The value of the constant n is a value preset in the system, and can be changed as needed. For example, the route distance between the current position X and the position Y on the route is calculated and set to be L / n. If the switch 10a is longer than the time (t0 seconds) and is operated continuously, the value of n can be set to N (N <n) to perform scrolling at a higher speed than usual (step). 802, 804).
[0051]
As described above, when the scrolling is started, the comparison processing unit 49 sets the center position on the map described on the screen at that time and the position information of the search result regarding the information around the route (the right item 1 and the left item). Item 1) is compared (step 805), and when the item is on the route behind the center position and behind the route target direction (step 806), the center position is determined by the temporary storage medium control. If the search result does not exceed the range of the search results stored in the device 5 (step 807), the update processing unit 50 causes the button display generation unit 48 to delete the item on the rear side and store it in the temporary storage medium. An image is generated by adding the item of the next order stored in the control device 5, and the button display control unit 8c performs button display again on the screen of the display device 9 based on the generated image (step). 809).
[0052]
When the scrolling is greatly performed and the prosecution result stored in the temporary storage medium control device 5 is insufficient (step 807), the search result stored in the temporary storage device at that time is discarded, and a new (Step 808), and the search result is displayed as a button (step 809).
[0053]
If the switch 10a corresponding to the button at the center of returning to the current position is selected after the scroll display is completed, the map displayed on the screen returns to the center of the current position and the temporary storage medium The search results around the route are displayed again using the data stored in the device. At this time, if the temporary storage medium control device 5 is once rewritten due to a large scroll amount, a search is performed again using the current position.
[0054]
[Effects of Embodiment]
According to the present embodiment as described above, the peripheral information of the route on the map is displayed as a button while maintaining its relative positional relationship, so that the user can always display the information on the map in the normal display state. The positional relationship between them can be easily grasped. In particular, even when the vehicle actually moves or virtually moves by a scroll operation, the button display is automatically updated in accordance therewith, so that appropriate information can always be obtained.
[0055]
In addition, when the user operates, a button is displayed just by touching the input device 10, so that only the map information is displayed in a normal use state, and the user is particularly conscious only when the operation or confirmation is required. Instead, a button appears on the map. Therefore, it is possible to present information and information necessary for an operation related to the information with a small operation load without particularly hindering the visibility of the map screen. Furthermore, since the item of the button display corresponds to the position of the switch 10a, even a driving user can easily operate by groping.

[Other embodiments]
The present invention is not limited to the above embodiments. For example, as a search condition of the surrounding information, a genre of a general landmark is set in advance without specifying the content of a specific genre (for example, a convenience store, a public facility, a store, a major company, Aggregates of genres such as buildings), and displaying search results of such genres by displaying buttons with the items as described in the above embodiment, rather than vaguely displaying symbols or the like on a map, around the route Can be clearly presented, and stable route traveling can be assisted.
[0057]
The following embodiment is also conceivable for the button display processing when the route is recalculated. This will be described with reference to the flowchart of FIG. That is, as described in the above embodiment, the result of the search for the peripheral information based on the calculated and set route is stored in the temporary storage medium control device 5 (step 901). When the vehicle is traveling on this route, display processing of the peripheral information is performed as in the above-described embodiment (steps 902 and 903).
[0058]
However, when the vehicle temporarily deviates from the preset route (step 902) and the route is recalculated, the surrounding information is searched and displayed again at the same time (step 902). Step 904). In this case, for example, the peripheral information on the previous route is distinguished as group A, and the peripheral information on the route up to the route is distinguished as group B, and stored in the temporary storage medium control device 5 (step 905).
[0059]
When the search results are displayed by buttons, those belonging to group A (step 906) are displayed in, for example, blue characters (step 907), and those belonging to group B (step 906) are displayed in, for example, red characters. It is displayed (step 908). In this way, by displaying the objects around the preset route and the objects around the newly set route separately, for example, the route may be erroneously moved temporarily. In the case where the route has temporarily deviated due to a detour, the information on the deviated route can be clearly distinguished from the information on the route to which the user should go. Makes it easy to make a decision on returning the route. Further, when the target happens to be at a place where the route turns, it is also possible to display the target in a color (for example, green) indicating that.
[0060]
In the present invention, the form and color of the button display, the number of items, the item contents, and the like can be freely changed. Not only characters but also symbols and figures such as landmarks can be displayed together. In addition, the number of switches of the switch matrix device can be changed as needed in accordance with the number of items in the button display. Further, the moving object to which the present invention is applied is not limited to a vehicle, but can be applied to any object such as an airplane and a ship.
