Then, the route search unit 10 controls the CD-ROM 4, reads road data of various areas from the area including the departure place to the area including the destination to the buffer memory unit 8 and outputs the read road data. The shortest optimal route connecting the starting point to the destination is searched by using the Dijkstra method, horizontal search method, etc., and the route data (position coordinate sequence) forming the searched optimal route is used as the guided route data in the guided route storage unit. 9 (steps S70 and S71 in FIG. 8). Then, the route guidance mode ON is stored in the mode storage unit 12 (step S72). If the route guidance mode is turned on by the operation unit 5 while the route guidance mode is off, the registration unit 1
3 stores the route guidance mode on in the mode storage unit 12, and if the operation unit 5 performs the route guidance mode off operation while the route guidance mode is on, the registration unit 13 stores the route guidance mode off in the mode storage unit 12. (Steps S73, S7
4 or S75, S76).

When the route guidance mode is turned on, the drawing unit 2
0 is determined to be YES in step S25 of FIG. 4, and a portion which is stored in the guide route storage unit 9 and is included in the area of the map image is drawn by superimposing the emphasized guide route that is thickly emphasized with a predetermined specific color. Yes (step S26). Therefore, since the emphasized guide route is displayed on the map image on the screen, the user can quickly reach the destination only by traveling along the emphasized guide route (see reference numeral GD in FIG. 9 (2)). After that, when reaching the destination, when the route guidance mode off operation is performed by the operation unit 5, the registration unit 13 registers the route guidance mode off as the route guidance mode data in the mode storage unit 12 (steps S75 and S76 in FIG. 8). ), The highlighted guide route display on the map image disappears (N in step S25 of FIG. 4).
O).

(3) Addition of map color pattern (3-1) When a map color pattern is created by the operation unit 5 for creating a map color pattern in the vehicle-mounted navigation device alone, a map color pattern is created. The registration unit 13 creates a map color pattern according to the map color pattern creation operation and adds it to the map color pattern storage unit 11 (see FIG. 5).

(4) Map drawing based on map color pattern desired by the user (4-1) Manual priority mode As described above, a large number of various colors are stored in the map color pattern storage unit 11 of the vehicle-mounted navigation device 1 by various methods. When it is desired to always display the map image with one desired map color pattern in the map color pattern storage unit 11 after storing the map color pattern of No. 1, first, the name of the desired map color pattern is first displayed on the operation unit 5. While specifying, select the map color pattern to be used in the manual priority mode. For example, when the map color pattern 4 in FIG. 2 is a desired map color pattern and navi2 is selected as the map color pattern used in the manual priority mode, the registration unit 13
In the map color pattern storage unit 11, the flag MF registered in association with the map color pattern of navi2 is set to 1, and the flag MF associated with other map color pattern is set.
Is set to 0 and it is registered that the use condition of the map color pattern 4 is the manual priority mode (step S4).
2, S43).

After that, when the operation section 5 is operated to switch the use mode of the map color arrangement pattern to the manual priority mode, the registration section 13 changes the map color pattern use mode data in the mode storage section 12 to the manual priority mode and the manual operation is performed. Turn on the priority mode (step S in FIG. 7).
54, S55). Then, since the drawing unit 20 is in the manual priority mode by checking the map color pattern use mode, it is determined to be YES in step S15 of FIG.
Using the map data around the current position stored in the buffer memory unit 8, a map image of a predetermined scale with the current position as the center and the north facing upward is displayed in the map color pattern storage unit 11

Therefore, regardless of the map color pattern defined in the map data, the expressway is magenta, the national road is pink, the general road is gray, the park is yellow-green, the river is blue, the sea is blue, and so on. A map image can be drawn and displayed in a desired map color pattern that is easy to see.

(4-2) Time zone priority mode After storing various map color arrangement patterns in the map color arrangement pattern storage section 11, the time zone is divided into the day time zone and the night time zone,
When it is desired to display a map image with a desired map color pattern in the map color pattern storage unit 11, first, while designating the name of the desired map color pattern with the operation unit 5,
Select the map color pattern to be used during the daytime in the time zone priority mode. For example, when the map color pattern 3 of FIG. 2 is a desired map color pattern, nav is used as the map color pattern used in the daytime zone of the time zone priority mode.
When i1 is selected, the registration unit 13 sets the flag DF registered in the map color pattern storage unit 11 in association with the map color pattern of navi1 to 1 and sets the flag DF associated with another map color pattern to 0. As a result, it is registered that the use condition of the map color pattern 3 is the daytime zone in the time zone priority mode (steps S44 and S45).

In the same way, the map color pattern to be used in the night time zone of the time zone priority mode is selected while designating the desired map color pattern name on the operation unit 5. For example, when the map color pattern 5 in FIG. 2 is a desired map color pattern and navi3 is selected as the map color pattern to be used in the night time zone of the time zone priority mode, the registration unit 13 causes the map color pattern storage unit 11 to register. Of the navi
Flag N registered in association with map color pattern 3
F is set to 1 and the flag NF associated with another map color arrangement pattern is set to 0, and it is registered that the use condition of the map color arrangement pattern 5 is the daytime zone of the time zone priority mode (steps S46 and S47). .

Thereafter, when the operation section 5 is operated to switch the map color pattern use mode to the time zone priority mode, the registration section 13 changes the map color pattern use mode data in the mode storage section 12 to the time zone priority mode. To turn on the time zone priority mode (steps S56 and S5 in FIG. 7).
7). Then, the drawing unit 20 is in the time zone priority mode by checking the map color pattern use mode, and thus determines YES in step S17 of FIG. At this time, the output of the time zone determination unit 17 is checked to determine whether the current time zone is day or night. If it is day (night), the buffer memory unit 8
Using the map data around the current position stored in, the map image of a predetermined scale with the current position as the center and the north facing upward is stored in the flag DF of the map color pattern storage unit 11.
Drawing is performed in the image memory section 19 according to the map color pattern of the map color pattern 3 (5) in which (NF) is 1 (steps S18, S19 (S20)). Therefore, regardless of the map color pattern defined by the map data, during the daytime (night), expressways are red, national roads are orange, general roads are white, parks are green, rivers are blue, seas are blue-purple, ...
・ (Highways are pink, national roads are orange, general roads are white, parks are green, rivers are blue purple, seas are blue, and so on.), So that the map is the easiest for the user to see during the day (night) hours. A map image can be drawn and displayed with a color arrangement pattern.

(4-3) Route guidance priority mode After storing various map color arrangement patterns in the map color arrangement pattern storage unit 11, the map color arrangement pattern storage unit is divided into the route guidance mode ON and OFF. When displaying a map image with a desired map color pattern in 11, the map color used when the route guidance mode of the route guidance priority mode is turned on while designating the name of the desired map color pattern on the operation unit 5. Select a pattern. For example, when the map color pattern 2 of FIG. 2 is a desired map color pattern, and when the sakura2 is selected as the map color pattern to be used when the route guidance mode of the route guidance priority mode is turned on, the registration unit 13 causes the map color pattern storage unit 11 to Of, s
The flag GOF registered in association with the map color pattern of akura2 is 1 and the flag GOF associated with another map color pattern is 0, and the use condition of the map color pattern 2 is the route guidance mode of the route guidance priority mode. Register that it is on (steps S50 and S in FIG. 7).
51).

In the same manner, while designating the name of a desired map color arrangement pattern on the operation unit 5, the map color arrangement pattern used when the route guidance mode of the route guidance priority mode is turned off is selected. For example, when the map color arrangement pattern 1 of FIG. 2 is a desired map color arrangement pattern, sa is used as the map color arrangement pattern used when the route guidance mode of the route guidance priority mode is off.
When kura1 is selected, the registration unit 13 sets the flag GNF registered in the map color arrangement pattern storage unit 11 in association with the map color arrangement pattern of sakura1 to 1, and sets the flag GNF associated with another map color arrangement pattern to 0. As a result, it is registered that the use condition of the map color pattern 1 is that the route guidance mode of the route guidance priority mode is off (steps S52 and S53).

After that, when the operation unit 5 is operated to switch the use mode of the map color arrangement pattern to the route guidance priority mode, the registration unit 13 changes the map color pattern use mode data in the mode storage unit 12 to the route guidance priority mode. To turn on the route guidance priority mode (step S58 in FIG. 7,
S59). Then, the drawing unit 20 is in the route guidance priority mode by checking the map color pattern use mode, and thus determines YES in step S21 of FIG. At this time, it is checked whether the route guidance mode data in the mode storage unit 12 is on or off, and if it is on (off), the map around the current position stored in the buffer memory unit 8 is checked. Using the data, a map image of a predetermined scale with the current position as the center and the north facing upward is displayed in the map color pattern storage unit 11 as a flag GOF.
Map color pattern 2 (1) where (GNF) is 1.
The image is drawn in the image memory unit 19 according to the map color arrangement pattern (steps S22, S23 (S24)). Therefore, regardless of the map color pattern defined by the map data, when the route guidance mode is on, the highway is pink, the national road is orange, the general road is gray, the park is yellow-green, the river is blue, the sea is blue,・ (Highway is orange, national road is pink, general road is gray, park is green, river is blue purple, sea is blue,
・ ・), The user can draw and display the map image with the map color pattern that is the easiest to see when the route guidance mode is on (off) and the highlighted guidance route exists (does not exist) on the screen. it can.

When the map color pattern use mode is one of the manual priority mode, the time zone priority mode and the route guidance priority mode, it is desired to turn off these modes and return to the original normal mode. When the operation mode for switching the map color pattern use mode to the normal mode is performed, the registration unit 13 changes the map color pattern use mode data in the mode storage unit 12 to the normal mode (steps S60 and S61 in FIG. 7). Therefore, the drawing unit 2
0 is determined to be YES in step S31 of FIG. 3, and map data around the current position stored in the buffer memory unit 8 is used to display a map image of a predetermined scale with the current position as the center and the north facing upward. Drawing is performed in the image memory unit 19 according to the map color arrangement pattern defined by the map data (step S14).

According to this embodiment, a desired map color pattern created by the vehicle-mounted navigation device 1 is stored in the map color pattern storage unit 11 or a map color pattern created by the external map display support device 70, 90. The pattern is directly transferred to the vehicle-mounted navigation device 1, or is stored in the map color pattern storage unit 11 with the portable external storage unit 30 interposed therebetween, or the map display support device 50 is provided with a large number of external map color pattern patterns. The map color arrangement pattern obtained from 60 via the network or directly or via the portable external storage unit 30 can be stored in the map color arrangement pattern storage unit 11. Then, for each map color pattern stored in the map color pattern storage unit 11, whether to use in the manual priority mode in advance, whether to use in the daytime zone of the time zone priority mode,
Usage conditions: whether to use in the night time zone of time zone priority mode, whether to use when route guidance mode of route guidance priority mode is on, whether to use when route guidance mode of route guidance priority mode is off If you register
When the map color pattern use mode is set to the manual priority mode, the map image is always drawn according to the desired map color pattern selected for the manual priority mode regardless of the map color pattern defined in the map data. However, the map image can be displayed, and the user can see the map image of the map color pattern that is most easily viewed according to the type of the display unit, the installation status of the device, and the like. Also, if the map color pattern use mode is set to the time zone priority mode,
Display the daytime zone with the desired map color pattern that is most visible to the user during the daytime, and display the nighttime zone with the desired map color pattern that is most visible to the user during the nighttime. You can also Furthermore, if the map color pattern use mode is set to the route guidance priority mode, both the highlighted guidance route and the map image are most easily seen by the user during route guidance to the destination by displaying the highlighted guidance route when the route guidance mode is on. It is also possible to display the map in a desired map color pattern and display it in a desired map color pattern that makes it easier for the user to see the map image without the emphasized guide route while the route guidance mode is off. If the user stores a large number of map color arrangement patterns in the map color arrangement pattern storage unit 11 in advance, an optimum map color arrangement pattern for each map color arrangement pattern use mode of manual priority mode, time zone priority mode, route guidance priority mode can be obtained. You can easily select and register.

In the above-described embodiment, the time zone priority mode is divided into the day time zone and the night time zone, but the morning time zone, the day time zone, the evening time zone, and the midnight time zone. It is divided into three or more N time zones, such as four time zones, and the user previously selects the map color pattern to be used for each time zone and registers it in the map color pattern storage unit. Incidentally, the time zone discriminating section discriminates any of the present N time zones, and the map display control section uses the map color pattern associated with the current time zone discriminated by the time zone discriminating section. A map image may be drawn.

Further, for one specific time zone such as the daytime zone, a map image may be drawn according to the map color arrangement pattern defined by the map data. In addition, when the route guidance mode is off in the route guidance priority mode, the map image is drawn according to the map color pattern selected by the user for turning off the route guidance mode in advance. When the mode is off, a map image may be drawn according to the map data. For example, the flowcharts of FIG. 3 and FIG. 4 are modified as shown in FIG. 16 and FIG. After determining “YES” in step S17, the map image around the current position is drawn according to the map color pattern defined by the map data (steps S18 and S19).
´). Further, when the route guidance mode is off under the route guidance priority mode, the drawing unit of the map display control unit determines YES in step S21 of FIG. 17, and then, according to the map color pattern defined by the map data, A map image is drawn (steps S22 and S24 ').

The time zone discriminating section discriminates the time zone from the present time. However, when the open / close signal of the headlight switch of the vehicle is input and the open / close signal indicates open, the time zone of the day, When it is closed, it may be determined that it is during the night time. In addition, the car navigation system is a CD-
Although the map data necessary for drawing the map image is read from the ROM, the CD-ROM reading unit is omitted and a map data storage unit such as a semiconductor memory in which the map data is stored in advance is provided in the vehicle-mounted navigation device.
