First Claim
1. A route setting method for use in a navigation system for navigating a movable body, said route setting method comprising:
- a process area setting process of setting a process area, which corresponds to a present position of said movable body, includes a plurality of route points and has a size based on a performance of a recovery route searching process, in case that the present position of said movable body does not exist on a set route from an original departure point to a final destination point, said set route including said route points and being set in advance; and
a route point searching process of searching a closest route point, which is the closest to said final destination point among said route points on a boundary of or within said set process areawherein said recovery route searching process searches a recovery route from the present position of said movable body to said searched closest route point.
