Abstract

A storage part of an on-vehicle apparatus stores simplified map data of which content is simplified as compared to original map data used for route guidance. An image generator of the on-vehicle apparatus retrieves the simplified map data stored on the storage part and generates a map image based on the simplified map data. Then a transmitter of the on-vehicle apparatus transmits the map image generated by the image generator to a portable device, in response to a demand from the portable device.

Claims

1. An on-vehicle apparatus used in a vehicle, the on-vehicle apparatus comprising:

a storage part that stores first map data having a simplified content as compared to second map data used for route guidance;

an image generator that generates a map image based on the first map data; and

a transmitter that transmits the map image to a portable device in response to a demand from the portable device that is a communication partner of the on-vehicle apparatus.

2. The on-vehicle apparatus according to claim 1, wherein

the first map data is map data in which a part of element data included in the second map data is omitted.

3. The on-vehicle apparatus according to claim 1, wherein

the first map data is map data in which a font type of text data included in the second map data is changed.

4. The on-vehicle apparatus according to claim 1, wherein

the first map data is map data in which a language type of text data included in the second map data is changed.

5. The on-vehicle apparatus according to claim 1, wherein

the first map data is map data in which an icon included in the second map data is changed.

6. The on-vehicle apparatus according to claim 1, further comprising:

a receiver that receives from the portable device destination information specifying a destination of the vehicle; and

a guidance part that executes the route guidance leading to the destination specified by the destination information.

7. The on-vehicle apparatus according to claim 1, further comprising

a data generator that generates the first map data based on the second map data.

8. A transmission method for transmitting data from an on-vehicle apparatus used in a vehicle, the transmission method comprising:

(a) obtaining first map data from a storage part that stores the first map data having a simplified content as compared to second map data used for route guidance;

(b) generating a map image based on the first map data; and

(c) transmitting the map image to a portable device in response to a demand from the portable device that is a communication partner of the on-vehicle apparatus.

9. The transmission method according to claim 8, wherein

the first map data is map data in which a part of element data included in the second map data is omitted.

10. The transmission method according to claim 8, wherein

the first map data is map data in which a font type of text data included in the second map data is changed.

11. The transmission method according to claim 8, wherein

the first map data is map data in which a language type of text data included in the second map data is changed.

12. The transmission method according to claim 8, wherein

the first map data is map data in which an icon included in the second map data is changed.

13. The transmission method according to claim 8, further comprising

(d) generating the first map data based on the second map data.

14. A non-transitory computer-readable storage medium that stores a program executable by a computer included in an on-vehicle apparatus used in a vehicle, and

execution of the program by the computer causes the computer to execute the steps of:

(a) obtaining first map data from a storage part that stores the first map data having a simplified content as compared to second map data used for route guidance;

(b) generating a map image based on the first map data; and

(c) transmitting the map image to a portable device in response to a demand from the portable device that is a communication partner of the on-vehicle apparatus.

15. The storage medium according to claim 14, wherein

the first map data is map data in which a part of element data included in the second map data is omitted.

16. The storage medium according to claim 14, wherein

the first map data is map data in which a font type of text data included in the second map data is changed.

17. The storage medium according to claim 14, wherein

the first map data is map data in which a language type of text data included in the second map data is changed.

18. The storage medium according to claim 14, wherein

the first map data is map data in which an icon included in the second map data is changed.

19. The storage medium according to claim 14, wherein

the execution of the program by the computer causes the computer to further execute the step of

(d) generating the first map data based on the second map data.
