ABSTRACT:
A route setting method for use in a navigation system for navigating a movable body is provided with a process area setting process of setting a process area, which corresponds to a present position of the 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 the movable body does not exist on a set route from an original departure point to a final destination point. The set route includes the route points and is set in advance. The route setting method is also provided with: a route point searching process of searching a closest route point, which is the closest to the final destination point among the route points on a boundary of or within the set process area; and the recovery route searching process of searching a recovery route from the present position of the movable body to the searched closest route point.
