Method and apparatus for adjusting distance for generating maneuver instruction for navigation system |
摘要 |
A distance adjustment method and apparatus for a navigation system produces a maneuver instruction for an intersection at the most appropriate timing and location during the route guidance. The method includes the steps of: searching an upcoming intersection on the calculated route that requires the user to make a turn therein; retrieving data concerning the upcoming intersection from a map database; adjusting a final distance from a reference point of the intersection by evaluating the retrieved data concerning the intersection; and generating a maneuver instruction at a timing when the user has reached the adjusted final distance from the reference point of the intersection, thereby notifying the user to make a turning maneuver at the intersection.
