Method for searching return path of moving object for use in navigation system

摘要

A navigation system of the present invention provides a user of a moving object with a return path on an original driving path when the moving object deviates from the original driving path. A method for searching the return path of the moving object for use in the navigation system comprises the steps of: searching and storing an original driving path of the moving object, and guiding the moving object along the searched driving path; deciding whether the moving object is deviated from the driving path; when the moving object is deviated from the driving path, deciding a start point and return points for returning the moving object on the original driving path; after searching respective paths from the start point to the return points, deciding a shortest path as an optimum return path; and guiding the moving object to the original driving path along the decided return path.
