Abstract

An apparatus for processing road information includes: a global positioning system (GPS) sensor configured to detect a location of a vehicle; a navigation device configured to output short-range road information and long-range road information according to a location of the vehicle; and a vehicle controller configured to restore forward road information by using the short-range road information and the long-range road information and control an engine or a transmission according to the forward road information.

Claims

1. An apparatus for processing road information, the apparatus comprising:

a global positioning system (GPS) sensor configured to detect a location of a vehicle;

a navigation device configured to output short-range road information and long-range road information according to a location of the vehicle; and

a vehicle controller configured to restore forward road information by using the short-range road information and the long-range road information and control an engine or a transmission according to the forward road information.

2. The apparatus of claim 1, wherein the navigation device outputs the short-range road information and the long-range road information at predetermined time intervals.

3. The apparatus of claim 2, wherein the vehicle controller restores the forward road information by accumulating the short-range road information and the long-range road information output at predetermined time intervals.

4. The apparatus of claim 3, wherein the vehicle controller restores the forward road information in further consideration of a movement distance of the vehicle within a predetermined time.

5. The apparatus of claim 1, wherein the short-range road information and the long-range road information include information regarding spots of a road spaced apart from one another at a predetermined distance therebetween, respectively.

6. The apparatus of claim 5, wherein a predetermined distance of the short-range road information is a first distance, a predetermined distance of the long-range road information is a second distance, and the second distance is greater than the first distance.

7. The apparatus of claim 5, wherein the vehicle controller restores forward road information corresponding to spots within sports of a road spaced apart from each other at a predetermined distance therebetween, by using the forward road information restored based on the short-range road information and the long-range road information.

8. A method for processing road information, the method comprising:

detecting a location of a vehicle using a global positioning system (GPS) sensor;

detecting short-range road information and long-range road information corresponding to a location of the vehicle; and

restoring forward road information with a vehicle controller by using the short-range road information and the long-range road information.

9. The method of claim 8, wherein in the detecting of the short-range road information and the long-range road information, the short-range road information and the long-range road information are detected at predetermined time intervals.

10. The method of claim 9, wherein in the restoring of the forward road information, the forward road information is restored by accumulating the short-range road information and the long-range road information detected at the predetermined time intervals.

11. The method of claim 10, wherein in the restoring of the forward road information, the forward road information is restored in further consideration of a movement distance of the vehicle within a predetermined time.

12. The method of claim 10, wherein the short-range road information and the long-range road information include information regarding spots of a road spaced apart from one another at a predetermined distance therebetween, respectively.

13. The method of claim 12, wherein a predetermined distance of the short-range road information is a first distance, a predetermined distance of the long-range road information is a second distance, and the second distance is greater than the first distance.

14. The method of claim 8, further comprising:

controlling an engine or a transmission according to the forward road information.
