Abstract

Disclosed is a method for sensing a traveling state based on a speed. The method for sensing the traveling state based on the speed includes outputting a mean speed C for each link with respect to a number of total traversing times of a predetermined path, and updating a reference speed B with the outputted mean speed C, and measuring a speed A while traversing the predetermined path, and comparing the measured speed A with the updated reference speed B, thereby displaying the traveling state.

Claims

1-17. -17. (canceled)

18. A system for guiding a path, the system comprising:

a storage unit configured to;

store road map data and path guide data related to the road map data;

a controller configured to;

ascertain a current position of a vehicle using Global Positioning System (GPS) signals received via a GPS receiver, and the path searching unit configured to search for a path from the current position to a destination using the road map data in the storage unit;

provide a path guide based on the path;

request for speed information of each link to another device, the link indicating a unit section on a road map related to the path, and

receive the speed information from the another device;

measure a current speed for each link, compare the current speed with the speed information and determine a current traveling state of the vehicle; and

a display unit configured to;

display the determined traveling state of the vehicle.

19. The system of claim 18, wherein the controller further configured to collect a link speed from a user terminal.

20. The system of claim 18, wherein the controller further configured to send the current speed to the another device.

21. A method for guiding a path, the method comprising:

storing road map data and path guide data related to the road map data;

ascertaining a current position of a vehicle using Global Positioning System (GPS) signals received via a GPS receiver, and the path searching unit configured to search for a path from the current position to a destination using the road map data in the storage unit;

providing a path guide based on the path;

requesting for speed information of each link to another device, the link indicating a unit section on a road map related to the path, and

receiving the speed information from the another device;

measuring a current speed for each link, compare the current speed with the speed information and determine a current traveling state of the vehicle; and

displaying the determined traveling state of the vehicle.

22. The method of claim 21, wherein the receiving step further includes collecting a link speed from a user terminal.

23. The method of claim 21, wherein the method further includes sending the current speed to the another device.
