If the selected attribute icon is an attribute icon indicating a facility, the navigation apparatus according to the invention of claim 4 displays a related point icon indicating a related point at the position of the related point, and the selected attribute icon is If it is an attribute icon indicating a road, the road searched as the related point is highlighted.
The road highlighting means that the corresponding road is displayed so as to be distinguishable from other roads.

  When determining a desired road from the roads displayed as related points, the navigation device according to the invention of claim 5 is determined as a passing road that passes through the road or as a bypass road that bypasses the selected road. One of the two is displayed so that it can be selected.

  According to the navigation device of claim 1, by selecting and dragging and dropping an attribute icon to a desired position on the map, a point such as a facility or road having the same attribute as the attribute icon is used as a related point from the periphery. Search and display. Therefore, even if the operator does not know the address to be set as an accurate destination, the destination is definitely set with information within the range stored in the operator without requiring the address information. be able to.

  According to the navigation device of the second aspect, when a plurality of related points having the same attribute as the selected attribute icon are searched, they are displayed in the order closer to the designated position. Therefore, the display order of the points required by the operator is accelerated, and the labor for selecting the points can be reduced.

  According to the navigation device of the third aspect, when the selected attribute icon is an attribute icon indicating a road, a road within a predetermined range from the designated position is searched and displayed as a related point. Therefore, it is possible to set the facility and the road by the same operation, and the operability is improved.

  According to the navigation device of the fourth aspect of the invention, when the selected icon is an attribute icon indicating a road, the related point icon indicating the related point is displayed at the position of the related point, and the selected attribute is displayed. If the icon is an attribute icon indicating a road, the road searched as the related point is highlighted. Therefore, since different displays are provided for the facility and the road, it is possible to set the same operation, and to reduce operation mistakes.

  According to the navigation device of the fifth aspect of the present invention, when a desired road is determined from the roads displayed as related points, the road is determined as a passing road that passes through the road, or the detour road that bypasses the selected road Is selected and displayed as selectable. Therefore, it is possible to designate the passing road and the bypass road by the same operation, and the operability is improved.

Furthermore, each point data is given an attribute. For example, the attribute is based on a feature type such as “facility” or “road”, or based on a facility type such as “store”, “office”, or “hospital”. Attributes based on store type such as “convenience store”, “supermarket”, “bookstore” are set.
And the content of map information DB84 is updated by downloading the update information delivered via the communication part 6 from the map information delivery center.

The attribute icon storage unit 91 stores attribute icons relating to the attributes of points. The attribute icon represents the point attribute as an icon. Like the point attribute, the feature type such as “facility” and “road”, and the facility type such as “store”, “office”, and “hospital” Or, it is set based on the store type such as “convenience store”, “supermarket”, “bookstore”.
For example, a bookstore attribute icon is shown with a book open design, and a hospital attribute icon is shown using a map symbol. Also, the user can change the attribute icon or create an original icon as his / her icon and associate it with a specific attribute icon.

  In the present embodiment, an attribute icon string storage unit 92 is provided. The attribute icon string storage unit 92 is a memory area in which attribute icons that are likely to be used by the user are stored by user selection, and is an area for storing dragged attribute icons. When implementing the present invention, an attribute icon may be dragged directly from the attribute icon storage unit 91, but a frequently used item is stored in the attribute icon string storage unit 92 and used as in the present embodiment. be able to. Of course, it is also possible to store in advance those that are used relatively frequently on the manufacturer side.

The point determination unit 94 is displayed on the display 3 and displays a point having the same attribute as the dragged attribute icon as a related point icon, and a point selected by the user from the displayed point is set as a destination, a transit point, a detour point, or the like. Determine.
Note that the related point icon of the searched point having the same attribute as the dragged attribute icon is usually the same icon, but in the present embodiment, the icon dragged by the user for setting the point is the attribute icon. The icon indicating the position of the peripheral spot having the same attribute as the attribute icon is distinguished as the related spot icon.

  Next, the control of the navigation device according to the present embodiment processed by the calculation / control unit 1 will be described together with the screen display of the display 3.

  In FIG. 2, a main menu screen is displayed on the display 3 by executing a main program (not shown). By selecting various settings 22 from the main menu screen, various setting screens shown in FIG. 3 are displayed. Here, when the icon sequence creation 23 is selected, a program of “attribute icon sequence creation routine” is executed. When the spot setting 24 is selected, a “point setting routine” program is executed.

FIG. 4 is a flowchart of the “attribute icon string creation routine” of the navigation device of the first embodiment, which is called during execution of the main program of the navigation device.
First, in step S11, as shown in FIG. 5, one attribute icon row 31 is displayed at the top of the display 3. The attribute icon column 31 is not limited to one column, and may be two or more columns.

  Below the attribute icon column 31, each attribute icon stored in the attribute icon storage unit 91 is displayed together with the attribute and comment of the point indicated by each, and a scroll instruction 39 moves all the attribute icons up and down.

  An erasing area 32 is provided at the bottom of the display 3. That is, by dragging and dropping an attribute icon in the attribute icon row 31 to the erasing area 32, an unnecessary attribute icon in the attribute icon row 31 can be erased. Of course, when one or two icon rows 31 are saturated, they may be deleted sequentially. In the present embodiment, the use of the attribute icon row 31 is reduced as much as possible so as not to obstruct the display screen of the map 34 as a background. Here, formally, the attribute icon in the attribute icon row 31 is deleted from the attribute icon row 31 by dragging and dropping it to the erasing area 32, but the attribute icon exists in the attribute icon storage unit 91.

  When a specific attribute icon is dragged from the attribute icon display unit 30 in step S 12 and dropped in the attribute icon column 31 in step S 13, the attribute icon is copied to the attribute icon column 31. That is, when the frequently used attribute icons 31a, 31b, 31c, and 31d are sequentially selected in step S14, they are arranged in the attribute icon row 31. When the end area 33 is selected in step S15, the operation of adding the attribute icon to the attribute icon row 31 is completed. If the end area 33 is not selected in step S15, the routine from step S11 to step S15 is repeatedly executed.

  If it is determined in step S16 that a specific attribute icon in the attribute icon column 31 has been dragged, and if it is determined in step S17 that it has been dropped in the erase area 32, the corresponding attribute icon is extracted from the attribute icon column 31 in step S18. If the space for the corresponding attribute icon deleted from the attribute icon sequence 31 in step S19 is eliminated and the end area 33 is selected in step S20, the operation of deleting the attribute icon in the attribute icon sequence 31 is completed. If the end area 33 is not selected in step S20, the routine from step S11 is repeatedly executed.

In this way, by storing attribute icons that are frequently used in the attribute icon string storage unit 92, it is possible to use them with good operability. The attribute icon string storage unit 92 may store one or two or more attribute icons.
In the present embodiment, a case has been described in which a copy of an attribute icon in the attribute icon storage unit 91 is moved to the attribute icon string storage unit 92 or deleted. When an attribute icon is extracted from the icon storage unit 91 and moved to the attribute icon string storage unit 92, the attribute icon is erased from the attribute icon storage unit 91, and the attribute icon is extracted from the attribute icon string storage unit 92 and assigned to the attribute icon. When moving to the icon storage unit 91, the attribute icon may be controlled to appear in the attribute icon storage unit 91.

  Further, in the navigation device of the present embodiment, the attribute icons used by the “attribute icon sequence creation routine” shown in FIG. 4 are picked up from all the attribute icons stored in the attribute icon storage unit 91 and stored in the attribute icon sequence. However, in the case of carrying out the present invention, drag and drop is directly performed from the attribute icon storage unit 91 and dropped to a desired position on the map 34. May be. At this time, it is more efficient to collectively display the attribute icons.

  In such a use, when the attribute icon is dragged, if the display of the other attribute icon is removed from the display 3, it is possible to prevent the map 34 in the background from being difficult to see, and a specific attribute icon is dragged. This makes it possible to improve the drag-and-drop operability.

Next, the control of the navigation device according to the present embodiment processed by the calculation / control unit 1 will be described together with the screen display of the display 3.
6 and 7 are flowcharts of the “point setting routine” of the navigation device according to the first embodiment, and are called during execution of the main program of the navigation device.
When the spot setting 24 in FIG. 3 is selected, the “point setting routine” program shown in FIG. 6 is executed, and a map around the current position is displayed in step S31. In step S32, the attribute icon sequence 31 is superimposed. FIG. 8 corresponds to this state. In step S33, it is determined whether or not the attribute icon has been dragged, and steps S32 and S33 are repeatedly executed until the drag is present.

  That is, in the attribute icon column 31, for example, bookstore, school, park, and road attribute icons registered by the user are displayed as a bookstore icon 31a, a school icon 31b, a park icon 31c, and a road icon 31d. On the display 3, an attribute icon row 31 is superimposed on the display of the map 34 on the entire surface. The attribute icon row 31 shown in the figure includes four attribute icons. Specifically, the number registered by the user is displayed.

  If it is detected in step S33 that a specific attribute icon has been dragged, it is determined in step S34 whether or not the selected attribute icon is a road icon 31d. When it is the road icon 31d, the processing starts from step S50 described later. If the scale of the map is very small in step S35, the location to be dropped becomes ambiguous, so the scale of the map 34 is set to an appropriate scale. At this time, for example, if the bookstore icon 31a is selected, the distance from the current position to the nearest bookstore can be searched through the attribute, and the scale can be adjusted accordingly. At the same time, if there is a need for scrolling, scrolling is performed in step S36. Until the drop of the attribute icon is confirmed in step S37, the routine of steps S34 to S37 is performed.

For example, a case where a bookstore is set as a destination using the bookstore icon 31a as an attribute icon related to a facility will be described.
In step S33, the bookstore icon 31a is dragged with the fingertip to select the bookstore icon 31a from the attribute icon row 31, and the operator drops it to the place considered as the destination in step S37 as shown in FIG. That is, in step S33 and step S37, the position is designated by selecting an attribute icon in the attribute icon row 31 and performing drag and drop to drop it at a specific location.

    If the designation of the position by the drop of the attribute icon is confirmed in step S37, a point having the same attribute as the attribute icon is searched from the periphery of the drop position as a related point in step S38, and the related point searched is the related point icon in step S39. Display as. Here, as shown in FIG. 10, the related point to be searched for and displayed with respect to the position of the dropped attribute icon may be a related point icon indicated by a broken line at the nearest point, as shown in FIG. It is good also as a related point icon shown with the oblique line and broken line of several points within a specific distance range.

  Next, in step S40, whether to set the related point indicated by the related point icon as a destination or the like or to select “next candidate” is set as shown in FIG. This is performed on the candidate selection screen display 35, and the determination input is waited. If “setting” is not selected in step S41 and “next candidate” is selected, a related point icon of another related point is displayed in step S42, and step S38 to step S41, and further, if necessary, step The routine of S42 is repeatedly executed.

  When “setting” is selected in step S41, the map is set so that the position of the related point icon is the center of the screen in step S43, as in the related point icon indicated by the broken line moved toward the white arrow in FIG. 34 is scrolled. Then, in step S44, the “Destination” setting or “Via-point” setting is performed on the destination / via-point selection screen display 36 of FIG. 12, and the input is awaited. If “route” is selected, the related point is set as a route in step S45, and if “destination” is selected, the related point is set as the destination in step S46.

  As described above, when it is determined in step S34 that the selected attribute icon is the road icon 31d, scrolling is performed as necessary in step S50, and the road icon 31d is dragged and dropped on the map. The position is confirmed in step S51, a road around the drop position is searched in step S52, and is highlighted as a related point in step S53. The road highlighted at this time is, for example, one section between the branch points of each road, and as shown in FIG. 13, from the position of the road icon 31d dropped in step S51, the nearest road L1 and road L2 are displayed. The link is searched, and the link of the road L1 that is closest to the position where the road icon 31d is dropped is highlighted in a predetermined color.

  In step S54, whether or not to “set” the location where the related icon is indicated as a destination or waypoint or to select “next candidate” is displayed on the selection screen display 35 as shown in FIG. , Wait for the judgment input.

At this time, roads are highlighted from the order close to the position of the dropped road icon 31d. However, this order can be arranged in order of road scales such as national roads, prefectural roads, and city roads. Further, a road surrounding the position of the dropped road icon 31d can be highlighted as a related point. At this time, the candidate can be moved clockwise or counterclockwise.
Here, for the position of the dropped road icon, the road searched and displayed from the vicinity of the position may be the closest road or a plurality of roads within a specific distance range.

When “setting” is selected in step S55, the map is scrolled so that the selected road becomes the center of the screen in step S57. Then, in step S58, “Destination” setting or “Via-point” setting is performed on the destination / via-point selection screen display 36, and the input is waited. When “route” is selected, the related point is set as a route at step S59, and when “destination” is selected, the related point is set as the destination at step S60.
Then, in step S61, the selection of whether the selected road is set as a passing road or a bypass road is awaited (FIG. 15). When the passing road is selected, the passing road is set in step S62, and when the bypass road is selected, the bypass road is set in the navigation device in step S63.

  Here, when a passing road is set, a route that passes through the set road is searched. Specifically, when a passing road is set in a state where a route to the destination has already been searched, the route is searched again, and the route is changed to a route passing through the passing road. In addition, when a passing road is set in a state where no route is searched, a route passing through the passing road is searched when a route search is performed thereafter.

  In addition, when a detour road is set, a route that detours the set road is searched. Specifically, when a detour road is set in a state where a route to the destination has already been searched, the route is re-searched and changed to a route detouring the detour road. In addition, when a bypass road is set in a state where no route is searched, a route that does not pass through the bypass road when a route search is performed thereafter is searched.

  For example, when traveling with a navigation function and stopping at a convenience store to obtain traffic information such as traffic jams and road obstacles, the road icon 31d is set on the route searched for by the navigation function and a detour road is selected. A route that does not pass through the road is searched.
