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.

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. - View Dependent Claims (19, 20)
