When searching for a recommended route, it is preferable that the scale is set so that roads having a predetermined width or more that are candidates are displayed. First screen (1
7) and the map displayed on the second screen (18) are not necessarily fixed right above the map to be exactly north, that is, the left and right on the displayed map and the left and right of the user driving the car. The navigation device (1
Preferably, the switching is performed in accordance with the traveling direction of the vehicle on which (0) is mounted. For example, so that the map traveling direction is within a range of + -90 ° with respect to directly above on the display map,
The direction directly above the map is automatically rotated in two directions, true north or true south, or the traveling direction is + -4 with respect to the direction directly above the displayed map.
The map is automatically rotated in 90 ° increments so that the direction directly above the map is true north, true east, true south, or true west so that it is within the range of 5 °. preferable.

As described above, in the full screen of the monitor screen (16) of the map including the current position (25), the portion of the recommended route ahead from the current position (25) is small. In 10), the monitor screen (16) is the first screen
(17) and the second screen (18) are divided in the long side direction. In the full screen, the part of the recommended route (24) which protrudes outside from the long side from the monitor screen (16) is changed to the second screen. It is displayed on the screen (18), and the user can know the recommended route (24) with a sufficiently detailed map up to the map information in a range sufficiently ahead of the current position (25).

According to the navigation device (10) of the present invention, the frame (26) is set inside the periphery of the first screen (17),
When the current position (25) within the frame (26) exceeds the outside of the frame (26), the first screen is displayed so that the current position (25) is included in the frame (26).
Automatically update the area range displayed in (17).

In the area range of the area displayed on the first screen (17), the current position (25) is set to be substantially at the center in the updated display map of the first screen (17). It is preferable, but not limited to this, that it suffices to come within the frame (26).

In this manner, the first screen (17) displays the current position (2
Automatically updated with the change in 5), so that the user can save the trouble of scroll operation.

According to the navigation device (10) of the present invention, the second screen is linked to the update of the display of the first screen (17).
Update (18).

The display update of the second screen (18) is performed on the first screen.
It is not limited to immediately after the display update in (17), but may be after a while.

Thus, the second screen (18) also displays the current position.
Automatic updating is performed according to the change in (25), so that it is possible to save the trouble of the scroll operation by the user.

According to the navigation device (10) of the present invention, the first screen (17) and the second screen (18) display the recommended route (2).
The display area range is set so that there is a predetermined overlapping part in 4).

By setting an overlapped cover portion on the recommended route (24) of the first screen (17) and the second screen (18), the first screen (17) and the second screen (18) The connection relationship of the recommended route (24) becomes clear.

According to the navigation device (10) of the present invention, a relative position display mark indicating on which side the map on the second screen (18) is adjacent to the map on the first screen (17). (36) is displayed on the second screen (18).

The relative position display mark (36) has four vertical,
Any one of the directions may be indicated, or a total of eight directions may be added in an oblique direction.

With such a relative position display mark (36), the user can determine which recommended route (24) on the second screen (18) is located with respect to the first screen (17). You can know clearly.

According to the navigation apparatus (10) of the present invention, when the monitor screen (16) is a horizontally long rectangle, the first screen (17) and the second screen (17) in the horizontal direction of the monitor screen (16). The positional relationship of the first screen (17) and the second screen (1)

If the arrangement relationship between the first screen (17) and the second screen (18) in the horizontal direction of the monitor screen (16) is fixed, it may be inconvenient. For example, although the display map of the second screen (18) is the left map of the display map of the first screen (17), the first screen (17) and the second screen (18) Are arranged to the left and right in the horizontal direction of the monitor screen (16), respectively. In such a case, the first screen 17 and the second screen 17 in the horizontal direction of the monitor screen 16
It is easier for a user who looks at it to match the positional relationship of the screen (18). Therefore, the positional relationship between the first screen (17) and the second screen (18) in the horizontal direction of the monitor screen (16) is not fixed, and the first position in the horizontal direction of the monitor screen (16) is not fixed. The first screen (17) and the second screen (18) in the horizontal direction of the monitor screen (16) are aligned with the positional relationship between the map on the screen (17) and the map on the second screen (18). By switching the positional relationship, the map display can be easily understood by the user.

According to the navigation device (10) of the present invention, the recommended route (24) to the destination is displayed on the rectangular monitor screen (1).
In displaying the image on (6), the monitor screen (16) is divided into first and second screens in the wide direction, and both the first and second screens display the area range including the current position (25) on the same scale. A recommended route (24) is superimposed on the first screen, and information different from the recommended route (24) is superimposed on the second screen.

Another information superimposed on the second screen is, for example, VICS information.

The recommended route (24) and other information are not displayed in a superimposed manner on the same screen, but are displayed on different screens, so that the appearance of each screen is clear and each information can be easily understood. .

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a schematic configuration diagram of the on-vehicle navigation device 10. Car navigation system
Reference numeral 10 is mounted on an automobile, and includes a device main body 11 and a monitor 12 which receives display data and the like from the device main body 11 and performs a predetermined display on a monitor screen 16. Control unit 13 of device body 11
Reads map data from the map database CD-ROM 14 set in the CD drive. In the map database of the map database CD-ROM 14, map data of a predetermined area range is recorded at a plurality of levels corresponding to the scale of the map. An example of a map level is "
There are two levels: a “detailed map” and a “wide area map.” The “detailed map” is a predetermined width or more that is selected as a recommended route search candidate when a recommended route is calculated by an in-vehicle navigation device (for example, a width of 5). .5m or more) is a map that displays all roads, and the "wide area map" is a map that includes a larger area than the detailed map in the same display area with a reduction rate higher than that of the detailed map. Expressway is included, but width 5.
It does not include narrow roads of about 5m. The current position detection device 15 of the device main body 11 detects the current position of the vehicle by using GPS or gyro. The device body 11 is a map database C
Based on the map data read from the D-ROM 14, a recommended route from the current position to the destination specified by the user is searched. The recommended route is limited to a road having a predetermined width or more. The monitor screen 16 of the monitor 12 is horizontally long and substantially rectangular, and various scale maps such as a detailed map and a wide area map are displayed on the monitor screen 16. The monitor screen 16 is
In addition to the full display of the individual maps, the current map screen 17 and the route forward map screen 18, which are divided into two equal parts in the horizontal direction as appropriate by the user operation, can be displayed. .

The current map is a detailed map of the area including the current position 25, and the route ahead map is a recommended route 24 following the recommended route 24 of the current map toward the destination. It shall refer to a detailed map of the area range that includes and does not include the current position 25.

FIG. 2 shows the current map screen 17. Recommended route 24 from current position 25 to destination according to user's instruction
Is determined, and the recommended route 24 is distinguished from the other 23 by a color or the like. From the current position 25, an arrow indicating the traveling direction of the vehicle extends. The calculation frame 26 is displayed on the current map screen 17
Is set only for calculation as consisting of each side of the rectangle extending along the line inside by an overlap margin 28 from each side of the above, and is not displayed. The intersection 27 is computationally defined as the intersection of the recommended route 24 and the calculation enclosure 26.

In this vehicle-mounted navigation device 10, the traveling direction of the vehicle on which it is mounted is displayed on the current map screen 17.
In order to prevent the display map (especially detailed map) on the route ahead map screen 18 from being turned downward, the display map on the current map screen 17 and the route ahead map screen 18 changes the rotation position at intervals of 90 ° according to the traveling direction of the vehicle. It can be switched. That is, when the traveling direction of the vehicle is within + -45 ° with respect to true north, true east, true south, and true west, respectively, the right above the current map screen 17 and the route forward map screen 18 are respectively true. Switched to North, True East, True South, and True West.

FIG. 3 shows the monitor screen 16 in a display state before the correction processing of the route ahead map screen 18. In the state of FIG. 3, the maps on the current map screen 17 and the route ahead map screen 18 are:
A single map is displayed like the full screen display of the monitor screen 16 while the current position 25 is placed in the range of the current map screen 17. The recommended route 24 is displayed on the current map screen 17 and the route ahead map screen 18. Are continuous without any discontinuity or interruption at the screen boundary 34 of. That is, the map display of the current map screen 17 and the map display of the route ahead map screen 18 are connected at the screen boundary 34 without overlapping or interruption. FIG.
In the above, the vertical deviation amount line 31 and the vertical reference line 32 are not actually displayed, but are only set for calculation, and are both set in the monitor screen 16 in parallel with the horizontal side of the monitor screen 16. , The vertical deviation amount line 31 passes through the intersection 27, and the vertical reference line 32 currently passes through the center of the map screen 17. The vertical allowable range 33 is defined as a range between two parallel lines separated by a predetermined equal distance up and down with respect to the vertical reference line 32,
It can be appropriately adjusted by user setting together with a lateral allowable range described later. When the vertical deviation amount line 31 is within the vertical allowable range 33, the route forward map screen 18 is not corrected in the vertical direction. On the other hand, when the vertical deviation amount line 31 is out of the vertical allowable range 33, the distance a between the vertical deviation amount line 31 and the vertical reference line 32 is set as shown in FIG. The correction is made as the correction. Note that a is positive and negative when the vertical deviation amount line 31 is above and below the vertical deviation amount line 31, respectively.

FIG. 4 shows the monitor screen 16 in a display state of the route ahead map screen 18 after the correction processing. The route ahead map screen 18 of FIG. 4 is different from the route ahead map screen 18 of FIG.
(If a is negative, it will move upward by the absolute value of a), and it has been moved to the right by the overlap 28. That is, in FIG. 4, the point of the intersection 27 on the current map screen 17 appears at the intersection 27b on the route ahead map screen 18.

FIG. 5 illustrates the principle of correcting the route forward map screen 18 in FIG. 4 in the horizontal direction. That is, the current map screen 17 and the route ahead map screen 18 overlap in the horizontal direction.
Only the overlap display is performed, and the recommended route 24 of the route forward map screen 18 is displayed from the intersection 27c as the same point as the intersection 27, not from a position protruding from the screen boundary 34 on the current map screen 17.

FIGS. 3 to 5 illustrate the case where the recommended route 24 exits the right side of the current map screen 17 on the current map screen 17. However, the recommended route 24 may exit the left side and the upper side of the current map screen 17. The same shall apply. In other words, if the recommended route 24 exits the left side of the current map screen 17 on the current map screen 17, the intersection 27 becomes the recommended route 24 and the calculation frame line.
26, the route ahead map screen 18 is moved in the horizontal direction so that the intersection 27b as the same point as the intersection 27 comes on the right side of the route front map screen 18, and in the vertical direction. Similarly to FIG. 3, only when the vertical deviation amount line 31 does not fall within the vertical allowable range 33, it is moved downward by a. In FIGS. 3 to 5, the current map screen 17 and the route ahead map screen 18 are to be displayed in a fixed positional relationship of the left half and the right half of the monitor screen 16, respectively. When the route 24 exits the left side of the current map screen 17, the current map screen 17 and the route front map screen 18 are reversed in the left-right relationship, and are respectively displayed on the monitor screen.
It may be displayed in the right half and the left half of 16.
In the current map, the current position 25 is displayed. Therefore, even if the display locations of the current map screen 17 and the route ahead map screen 18 are opposite to each other, the user can determine whether the left or right side of the monitor screen 16 is the current map screen 17 or It is possible to correctly recognize whether or not the screen is the route ahead map screen 18. Further, which of the left and right is the current map screen 17 and the route ahead map screen 18 may be clearly displayed by characters or the like. If the recommended route 24 exits the upper side of the current map screen 17 on the current map screen 17, the intersection 27 is
And the upper side of the calculation enclosure frame line 26, and in the route ahead map screen 18, the intersection 27b is on the lower side of the route ahead map screen 18 in the vertical direction with respect to the route ahead map screen 18 before correction. Thus, in the horizontal direction, only when the intersection 27 exceeds the horizontal allowable range, the lateral deviation amount b (assuming the xy coordinates with the origin at the center of the current map screen 17 and the intersection
The x-coordinate position of 27 is defined as a lateral deviation amount b. 3), only when the lateral deviation amount line does not fall within the lateral allowable range, as in FIG. 3, is moved to the left by b.

FIG. 6 shows a relative position mark 36 displayed on the route ahead map screen 18. The relative position mark 36 indicates the relative position of the route ahead map screen 18 with respect to the current map screen 17. The relative position mark 36 in FIG. 6 indicates that the area range displayed on the route forward map screen 18 is on the right side of the area range currently displayed on the map screen 17.

FIG. 7 shows various examples of the relative position mark 36. Although FIG. 7 shows eight directions, the diagonal direction may be omitted and only four directions of up, down, left, and right may be used. Also, as described above, in the map display of the detailed map,
In order that the left-right relationship between the user driving the car and the map on the current map screen 17 and the map on the route ahead map screen 18 is not reversed, the direction directly above the map on the current map screen 17 and the map on the route ahead map screen 18 is It is automatically switched to one of four rotational positions at intervals of 90 ° according to the traveling direction.
Therefore, of the relative position marks 36 in FIG. 7, those directly below, diagonally lower left, and diagonally lower right are not used.

FIG. 8 shows the front display control button 37 on the current map screen 17. The monitor screen 16 is a touch panel type, and the user can switch on (display execution) and off (stop display) the display of the route front map screen 18 by touching the front display control button 37 with a finger. During the display of the route forward map screen 18, the display of the forward display control button 37 is set to "forward display OFF". By touching the forward display control button 37 with a finger, the route forward map screen 18 is switched from display to non-display. Can be While the route ahead map screen 18 is not displayed, the display of the front display control button 37 is “forward display ON”, and by touching the finger on the front display control button 37, the route forward map screen 18 is changed from non-display to display. Can be switched.

FIGS. 9 and 10 are flowcharts of a processing program for displaying the current map screen 17 and the route ahead map screen 18. In S50, it is determined whether the display of the front of the route is on or not. If the determination is Yes, the process proceeds to S51. If the determination is No, the processing program ends. S
At 51, it is determined whether or not the user has instructed the display of the recommended route 24. If the determination is Yes, the process proceeds to S52,
If No, the program ends. In S52,
A predetermined area range including the current position 25 is read in a detailed map.
At S53, the detailed map read at S52 is displayed on the monitor screen 16.
It is determined whether or not the current position 25 and the destination can be simultaneously displayed in the full screen assuming that the full screen is displayed. If the determination is Yes, the process proceeds to S54, and if the determination is No, the process proceeds to S55.
Proceed to. In S54, the detailed map read in S52 is displayed on the monitor screen 16 in a full screen, and the program ends. In step S55, the monitor screen displays a range corresponding to the size of the current map screen 17 in the detailed map read in step S52.
The current map screen 17 is displayed on the left half screen of 16. In the initial current map screen 17, the current position 25 is displayed almost at the center of the current map screen 17, or the current map screen 17 is displayed so that the display range of the recommended route 24 on the current map screen 17 becomes longer. So that it is displayed slightly below the center of.

The step S60 is executed after the step S55, and calculates the calculation frame 26 on the current map screen 17. S61
Then, the intersection 27 between the recommended route 24 and the calculation frame 26 on the current map screen 17 is calculated. In step S62, the current map screen is moved in the direction in which the recommended route 24 extends from the current map screen 17.
