Abstract

An automatic driving system includes: a reference driving information database for storing reference driving information including reference driving lines, reference driving speeds, and lane change information; and a navigation apparatus for searching a driving route from a starting point to a destination by using a position value of a vehicle and generating driving route information by reflecting the reference driving information in the searched driving route. The automatic driving system further includes a vehicle controller for determining a driving line and a driving speed by using the generated driving route information and performing unmanned automatic driving along the determined driving line at the determined driving speed.

Claims

1. A navigation apparatus comprising:

a global positioning system (GPS) receiver for receiving a position value of a vehicle from a satellite; and

a control unit for searching a driving route from a starting point to a destination by using the received position value and generating driving route information for unmanned automatic driving by reflecting reference driving information including a reference driving line and a reference driving speed in the searched driving route, wherein the reference driving information is built in a database.

2. The navigation apparatus of claim 1, wherein the control unit divides the driving route into multiple sections with respect to a direction change point and generates the driving route information by reflecting the reference driving line and the reference driving speed in each of the sections.

3. The navigation apparatus of claim 2, wherein the control unit additionally records lane change information for each of the sections in the driving route information.

4. The navigation apparatus of claim 1, wherein the reference driving line is generated by using an average driving path or a line connecting center points of each lane.

5. The navigation apparatus of claim 1, wherein the reference driving speed is generated by using an average speed or design speed of each road.

6. A method for providing a driving route using a navigation apparatus, comprising:

searching a driving route from a starting point to a destination by using a position value of a vehicle; and

generating driving route information by reflecting reference driving information including a reference driving line and a reference driving speed in the searched driving route, wherein the reference driving information is built in a database.

7. The method of claim 6, wherein, in said generating driving route information, the driving route is divided into multiple sections with respect to a direction change point and the driving route information is generated by reflecting the reference driving line and the reference driving speed in each of the sections.

8. The method of claim 7, wherein, in said generating driving route information, lane change information for each of the sections is additionally recorded in the driving route information.

9. The method of claim 6, wherein the reference driving line is generated by using an average driving path or a line connecting center points of each lane.

10. The method of claim 6, wherein the reference driving speed is generated by using an average speed or design speed of each road.

11. An automatic driving system comprising:
