Two configurations are shown.

In this figure, the CD-ROM decoder 12 is
An expressway navigation section 24 that performs navigation when driving on an expressway; a management section 26 that takes in an interchange (IC) name code output from the expressway navigation section 24 and outputs the IC position; and an output from the management section 26. A map access unit 30 according to the feature of the present invention that accesses the CD-ROM 28 reads the IC position output from the management unit 26, reads map data from the CD-ROM 28, and displays the map data on the display device 10. A display/drawing section 32 that supplies image data, and a display/drawing section 32 that supplies image data to a CD-ROM2.
The map navigation section 34 and -1 perform navigation based on map data read from 8 and 8.

That is, when driving on an expressway, based on the switching operation of the map switch 20, the expressway navigation section 24 captures the current position of the vehicle and a distance pulse emitted by a wheel sensor, for example, and informs the 10 people who have arrived. Related I
A C name code is issued. In the management section 26,
Based on this IC name code, the I
The C name code/latitude/longitude correspondence table section 28a is accessed. This IC name code/latitude/longitude correspondence table section 2
8a is a part that is stored in the CD-ROM 28+ and stores the 10 people included in the tail expressway map and the location (latitude, longitude) of the IC in correspondence.

The map access section 30 accesses the map data storage section 28b on the CD-ROM 28 based on the IC position read by the management section 26, and as a result, the map data stored in the map data storage section 28b is It is read into the display drawing section 32. In addition, this display drawing section 32
Since the IC position is also supplied from the management unit 26, the display/drawing unit 32 generates image data related to a map including the IC.

This generated image data is transferred to the display device 10, and a display is performed on the display panel 14 based on this image data.

Further, the map navigation section 34 performs navigation using a map displayed on the display panel 14.

On the other hand, when driving on general roads, the map navigation section 34
Navigation is performed based on map information that the display/drawing section 32 imports from the CD-ROM 2g.

Next, the operation of this embodiment will be explained using FIGS. 4 to 16.

FIG. 4 shows the initial setting operation in this embodiment.

First, after the operation is started (100) by turning on the power, etc., the map switch 16 is turned on by the operator (
102), a menu screen as shown in FIG. 9, for example, is displayed (104).

Here, it is assumed that the CD-ROM reproduced by the CD-ROM decoder 12 has, for example, a schematic expressway diagram as shown in FIG. 7 and a general road map as shown in FIG. . On the menu screen displayed on the display panel 14, there are touch switches 36, 38, 4.
0.42°44 is set. In step 106, these touch switches 36, 38, 40°4
By pressing any of 2.44, the mode of navigation operation is selected.

The touch switch 36.3g, 40, 42° 44 is
These switches correspond to the output of the national map, previous map, expressway map, previous expressway map, and store telephone guide, respectively. That is, in step 106, for example, when the touch switch 36 is pressed, the initial settings based on the national map (
108) is carried out, and normal map navigation (
110) is performed.

Similarly, when the touch switch 38 is pressed, the initial settings 112 and navigation 124 related to the navigation based on the map in the previous operation are performed, and the touch switch 42
When is pressed, initial settings 116 and navigation 1 related to navigation based on the expressway map from the previous operation are performed.
18 is performed and the touch switch 44 is pressed in the same way, thereby providing service information related to store telephone guidance (1
20) is performed.

When the touch switch 40 of the touch switches shown in FIG. 9 is pressed, the screen displayed on the display panel 14 shifts to, for example, an expressway selection screen as shown in FIG. 10 (122).

On this expressway selection screen, there is a touch switch 46.4.
8.50.52 is set. That is, when the operator presses the touch switch 46, the Kubbu Expressway is selected, and similarly, when the touch switches 48 and 50 are pressed, the Tomei Expressway and Meishin Expressway are selected, respectively. Further, the touch switch 52 is a so-called cursor key, and is a switch for scrolling the screen display on the display panel 14 in the vertical direction.

Here, when any of the touch switches 46, 48, 50 is pressed, steps 126, 128, 130, respectively.
to move to.

Here, a case where the touch switch 48 is pressed and therefore the Tomei Expressway is selected will be described as an example.

At this time, the display on the display panel 14 shifts from the expressway selection screen as shown in FIG. 10 to the section screen as shown in FIG. 11 (132). This section screen is a screen for selecting one section from a plurality of sections suitably divided into all sections of the Tomei Expressway, and on this screen,
A touch switch 54 for selecting the section Tokyo IC-Ashigara SA, a touch switch 56 for specifying the section Ashigara SA-Shizuoka IC, a touch switch 58 for specifying the section Shizuoka IC-Mikatahara PA, A touch switch 60 similar to the touch switch 52 in FIG. 10 is set.

Here, by pressing either of these touch switches 54, 56.degree. 58, the section related to the selection is manually selected (134), and the process moves to the next step 136.

Step 136 is set for each section shown in FIG. 11, and here, a case will be described in which the touch switch 54 is pressed in step 134 and therefore the Tokyo IC-Ashigara SA section is designated. In this case, step 136 (136-1) consists of step 138 for setting the start point of the expressway map and step 140 for setting the end point.

The screen displayed on the display panel 14 in step 138 is, for example, a screen as shown in FIG. 12.

A set switch 62, which is a touch switch, is set on this screen, and furthermore, a cursor switch 64, which is a touch switch indicated by a triangle in the figure, is set.
is set.

In this step 138, the cursor switch 64
By pressing , the cursor displayed above the point name will move. The location names displayed on this screen are, for example, interchange (IC), parking area (PA), service area (SA), etc. Additionally, a cursor may be displayed above each location name. After appropriately moving the cursor using the cursor switch 64 in this manner, the user presses the set switch 62 to set the starting point of the navigation based on the schematic highway diagram.

Next, step 140 relating to end point setting is executed. In this step 140 as well, the end point of the navigation related to the expressway schematic diagram is set by the same operation as in step 138.

The cursors representing the starting point and the ending point are each cursors in a stacked style, and in FIG. 13, the cursor for setting the starting point is represented by a cursor, and the cursor for setting the ending point is represented by a mouth. For example, in FIG. 13, the starting point is set at Oi Matsuda, and the ending point is set at Tokyo.

After the start point and end point are set in this way, the screen on the display panel 14 shifts to a start screen as shown in FIG. 14, for example. A start switch 66, which is a touch switch, is set on this screen.
By pressing the start switch 66 (142), navigation based on the expressway imitator is started (144).

FIG. 5 shows the map transition operation when the end point set in step 140 is reached.

In this case, the screen displayed on the display panel 14 is, for example, a screen as shown in FIG. 15, and an arrival warning 68 indicating arrival is displayed in a specific area of the screen (1
46). Also, for example, the inter map switch 67 shown in FIG. 147 is changed to a map switch 70 (148
).

Here, when the map switch 70 is further pressed by the operator (150), the screen displayed on the display panel 14 changes to display a general road map near the end point, for example, a general road map as shown in FIG. Migrate (152). and,
After this, the vehicle's own position is displayed on a general road map as shown in FIG. 16, and navigation (154) is performed based on this map.

In this way, upon arrival at the initialized end point, the map containing the end point of : is selected and displayed without having to be initialized again. FIG. 6 shows a map transition operation related to navigation when the user attempts to get off the expressway before reaching the end point set in step 140.

In this case, when the operator presses the intermap switch 67 as necessary (156), steps 140 to 154 are executed, similar to the map transition operation shown in FIG. 5, and the navigation shifts to the road map. do.

As described above, the device for displaying the vehicle's own position on a navigation map according to the present embodiment is particularly useful for the initial setting of the vehicle's own position when transitioning from navigation based on a schematic expressway diagram to navigation based on a general road map. It is possible to perform the transition without performing initial settings such as map selection again, omitting operations by the operator, and realizing an apparatus with improved usability.

In the above explanation, we have explained the transition from navigation based on expressway schematic diagrams to navigation based on general road maps, but conversely, when transitioning from navigation based on general road maps to navigation based on expressway schematic diagrams, Similarly, there is no need to perform initial settings again.

Also, as in this embodiment, step 1 related to end point setting
In a device having an operation corresponding to step 140, it is also possible to automatically shift to general road navigation without pressing the map switch 70 when the end point set in step 140 is reached. be.

Further, in this embodiment, a schematic expressway diagram in which the expressway is shown as a straight line is used, but this may be a map showing the actual shape of the expressway.

Furthermore, after the section is input in step 134, or after step 144 is executed and expressway navigation is started, by turning on the inter map switch 67, a road map relating to the specified section is displayed. Navigation may be performed based on the road map.

Further, in this embodiment, a touch switch set on the display panel 14 is used as a switch, but other switches such as a panel escutcheon switch may also be used.

[Effects of the Invention] As explained above, according to the present invention, when moving from the - map to another map, the navigation is transferred without the operator having to set the vehicle's own position or map selection again. Therefore, a navigation display device with improved usability can be obtained.
