Abstract

The apparatus includes an information collection unit configured to collect map information, information about the position of a vehicle, and base station information, a speed limit calculation unit configured to calculate a legal speed limit of a road on which the vehicle is driving, based on the map information, the information about the position, and the base station information, a speedometer display mode storage unit configured to store a number of differently set speedometer display modes for respective legal speed limits of the road, a speedometer display mode extraction unit configured to extract a speedometer display mode corresponding to the legal speed limit of the road among the number of differently set speedometer display modes depending upon the legal speed limit of the road, and a display unit configured to automatically change a previously displayed speedometer display modes to the extracted speedometer display mode.

Claims

1. An apparatus for controlling a speedometer for a vehicle, comprising:

an information collection unit configured to collect map information, information about the position of a vehicle, and base station information;

a speed limit calculation unit configured to calculate a legal speed limit of a road on which the vehicle is driving, based on the map information, the information about the position, and the base station information;

a speedometer display mode storage unit configured to store a number of differently set speedometer display modes for respective legal speed limits of the road;

a speedometer display mode extraction unit configured to extract a speedometer display mode corresponding to the calculated legal speed limit of the road among the number of differently set speedometer display modes; and

a display unit configured to automatically change a previously displayed speedometer display mode to the extracted speedometer display mode.

2. The apparatus for controlling the speedometer of claim 1, wherein the differently set speedometer display modes for respective legal speed limits of the road include different intermediate values.

3. The apparatus for controlling the speedometer of claim 1, wherein the differently set speedometer display modes for respective legal speed limits of the road include different intervals of graduation marks.

4. The apparatus for controlling the speedometer of claim 1, wherein the differently set speedometer display modes for respective legal speed limits of the road include different background colors.

5. The apparatus for controlling the speedometer of claim 1, wherein the map information is information about a map including a road on which the driving vehicle is positioned, and the base station information is information about a base station which wirelessly communicates with the vehicle.

6. A method for controlling a speedometer for a vehicle, comprising:

collecting map information, information about the position of a vehicle, and a base station information;

calculating a legal speed limit of a road on which the vehicle is driving, based on the map information, the information about the position, and the base station information;

extracting a speedometer display mode corresponding to the calculated legal speed limit of the road among the number of differently set speedometer display modes; and

automatically changing a previously displayed speedometer display mode to the extracted speedometer display mode.

7. The method for controlling the speedometer of claim 6, wherein the differently set speedometer display modes for respective legal speed limits of the road include different intermediate values.

8. The method for controlling the speedometer of claim 6, wherein the differently set speedometer display modes for respective legal speed limits of the road include different intervals of graduation marks.

9. The method for controlling the speedometer of claim 6, wherein the differently set speedometer display modes for respective legal speed limits of the road include different background colors.

10. The method for controlling the speedometer of claim 6, wherein the map information is information about a map including a road on which the driving vehicle is positioned, and the base station information is information about a base station which wirelessly communicates with the vehicle.
