Abstract

A vehicular display system includes an in-vehicle navigation device and a vehicular meter device. The in-vehicle navigation device includes a display device, a character string storing device, and a character string converting device. The character string storing device stores a navigation display character string that is to be displayed in the display device. The character string converting device converts the navigation display character string into a meter display character string. The vehicular meter device includes a navigation display area. The meter display character string is displayed in a navigation display area.

Claims

1. A vehicular display system comprising:

an in-vehicle navigation device; and

a vehicular meter device, wherein;

the in-vehicle navigation device includes;

a display for displaying first map data, wherein;

the first map data includes first character string data;

a character string storing means for storing the first map data that is to be displayed on the display; and

a transmitting means for transmitting map data to the vehicular meter device;

the vehicular meter device includes;

a receiving means for receiving the map data from the in-vehicle navigation device; and

a navigation display area for displaying second map data, wherein;

the second map data includes second character string data; and

a character string converting means for converting the first map data into the second map data is included in at least one of the following devices;

the in-vehicle navigation device; and

the vehicular meter device, wherein;

the second character string data is displayed in a simpler form than the first character string data in the navigation display area.

2. The vehicular display system according to claim 1, wherein:

the character string converting means is included in the in-vehicle navigation device;

the first character string data is navigation display character string data;

the second character string data is meter display character string data; and

the map data is;

transmitted to the vehicular meter device by the transmitting means; and

received from the in-vehicle navigation device by the receiving means, wherein;

the map data is the second map data.

3. The vehicular display system according to claim 1, wherein:

the character string converting means is included in the vehicular meter device;

the first character string data is navigation display character string data;

the second character string data is meter display character string data; and

the map data is;

transmitted to the vehicular meter device by the transmitting means; and

received from the in-vehicle navigation device by the receiving means, wherein;

the map data is the first map data.

4. The vehicular display system according to claim 1, wherein:

the character string converting means is included in;

the in-vehicle navigation device, wherein;

the first character string data is navigation display character string data; and

the second character string data is predetermined character string data, which is included in predetermined map data; and

the vehicular meter device, wherein;

the first character string data is the predetermined character string data; and

the second character string data is meter display character string data; and

the map data is;

transmitted to the vehicular meter device by the transmitting means; and

received from the in-vehicle navigation device by the receiving means, wherein;

the map data is the predetermined map data.

5. The vehicular display system according to claim 1, wherein a number of characters included in the first character string data is converted by the character string converting means.

6. The vehicular display system according to claim 1, wherein display design of the first character string data is converted by the character string converting means.

7. The vehicular display system according to claim 1, wherein:

the character string converting means includes a character string conversion database; and

the first character string data is converted by the character string converting means based on the character string conversion database.

8. The vehicular display system according to claim 7, wherein:

the character string conversion database includes a character string converting rank; and

the first character string data is converted by the character string converting means based on the character string converting rank.

9. The vehicular display system according to claim 1, wherein:

the vehicular display system includes a dynamic information obtaining means for obtaining dynamic information about a vehicle; and

the character string converting means converts the first character string data, based on the dynamic information, which has been obtained by the dynamic information obtaining means.

10. The vehicular display system according to claim 2, wherein:

the character string converting means includes a character string conversion database, wherein;

the character string conversion database includes;

the navigation display character string data; and

the meter display character string data; and

the navigation display character string data is converted by the character string converting means based on the character string conversion database.

11. The vehicular display system according to claim 4, wherein:

the character string converting means, which is included in the in-vehicle navigation device, includes a character string conversion database, wherein;

the character string conversion database includes;

the navigation display character string data; and

the meter display character string data; and

the navigation display character string data is converted by the character string converting means based on the character string conversion database.

12. The vehicular display system according to claim 2, wherein:

the character string converting means includes a character string conversion database, wherein;

the character string conversion database is included in a map data storing means for storing electronic map data; and

the map data storing means is further included in the in-vehicle navigation device; and

the navigation display character string data is converted by the character string converting means based on the character string conversion database.

13. The vehicular display system according to claim 4, wherein:

the character string converting means, which is included in the in-vehicle navigation device, includes a character string conversion database, wherein;

the character string conversion database is included in a map data storing means for storing electronic map data; and

the map data storing means is further included in the in-vehicle navigation device; and

the navigation display character string data is converted by the character string converting means based on the character string conversion database.

18. The vehicular display system according to claim 1, wherein:

the second character string data displayed in the simpler form is different from the first character string data in at least one of the following characteristics;

a character color;

a character size; and

a font.

14. A vehicular meter device comprising:

a receiving means for receiving first map data from an output medium, wherein;

the first map data includes first character string data;

a character string converting means for converting the first map data into second map data, wherein;

the second map data includes second character string data; and

a navigation display area for displaying the second map data, wherein;

the second character string data is displayed in a simpler form than the first character string data in the navigation display area.

15. A method for displaying a travel guidance map in a vehicle that has a navigation system and a meter display device, the method comprising:

producing display data including map data of a travel guidance map and first character string data indicative of a specified name for an indication of the specified name in a first form on the travel guidance map, the map data and the first character string data being stored in a memory of the navigation system;
