1. A navigation device comprising:
- a driving state tracker for tracking a mobile driving state using a current mobile position and RGI (Route Guidance Information) data including driving information on multi-routes from the current mobile position to a destination, and outputting deviation information and the current mobile position when a mobile object deviates from a mobile driving route among the multi-routes; and
a re-routing unit for searching partial routes from a mobile deviation position to each of the multi-routes using the deviation information, the current mobile position and the driving information on the multi-routes, and re-routing a route to the destination using each of the partial routes,wherein the re-routing unit calculates new multi-routes using the partial routes, the current mobile position and the driving information on the multi-routes, and determines a shortest distance route among the new multi-routes.

Abstract
A navigation device is provided. The device includes a driving state tracker for tracking a mobile driving state using a current mobile position and RGI (Route Guidance Information) data including driving information on multi-routes from the current mobile position to a destination, and outputting deviation information and the current mobile position when a mobile object is deviated from a route; and a re-routing unit for searching partial routes from a mobile deviation position to each of the multi-routes using the deviation information, the current mobile position and the driving information on the multi-routes, and re-routing a route to the destination using each of the partial routes.

13. A navigation method for a navigation device, the method comprising the steps of:
-
comparing driving information on multi-routes from a current mobile position to a destination with a mobile position on a map to determine a mobile driving state; determining whether a mobile object deviates from a mobile driving route among the multi-routes depending on the driving information; and if the mobile object deviates from the route, searching by a re-routing unit of the navigation device partial routes from a mobile deviation position to each of the multi-routes and re-routing a route to the destination using each of the partial routes, wherein the re-routing step comprises the steps of calculating new multi-routes using the partial routes, the current mobile position and the driving information on the multi-routes, and determining a shortest-distance route among the new multi-routes. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22)
