First Claim
Patent Images
1. A navigation apparatus comprising:
- a start point input part for inputting a start point;
a destination point input part for inputting a destination point;
a route setting part for setting a route from the start point to the destination point based on input data and various other data including map data; and
a display part for displaying the route, wherein the navigation apparatus provides a route guidance from the start point to the destination point, the navigation apparatus has a rerouting function for performing a search again during the route guidance, wherein the navigation apparatus further comprises a deviation point recording part for recording a deviation point as a search point for activating the rerouting function, and wherein the rerouting function is activated when a current location is within a predetermined distance from the deviation point.

Abstract
An navigation apparatus records a deviation point as a new search point for activating a rerouting function during a route guidance process. When the deviation point exists along or near a set route, it is predicted that a vehicle will travel away from the set route at the deviation point. When a current location is within a predetermined distance from the deviation point, the rerouting function is activated to automatically search for a new route starting from the deviation point.
