Route planning apparatus and method for navigation system
First Claim
1. A navigation system for route planning and route guidance, comprising:
- a display unit;
an information receiver adapted to receive information about current location of a vehicle;
at least one database to store and provide maps, road networks, geographical features, and point-of-interest (POI) information; and
a route planning processor for calculating and determining a route between a destination and a current vehicle position,wherein when a point is set up on a map unit after the route is generated by the route planning processor, the point is recognized as a waypoint on the route, and an optimized new route including the waypoint is generated by the route planning processor.

Abstract
A route planning system and method for a navigation system which allows the driver to intelligently plan the route when adding waypoints. The route planning navigation system includes a route planning processor which allows the driver to add and prioritize multiple POIs as waypoints. When one or more new waypoints are added, the driver is allowed to prioritize the waypoints if adding new waypoints does not significantly increase the cost of the route, and an optimized route is generated accordingly. In another aspect, if adding new waypoint significantly increases the cost of the route, a notifying message will be generated by the route planning processor so that the driver is able to make a decision whether to proceed to the new waypoint.

9. A method of route planning using a navigation system, comprising the following steps of:
-
providing an option to the driver to add more waypoints or POIs to an existing route; displaying POI categories, and detail POI information in a specific category selected by the driver; adding a new waypoint or POI; providing a notifying message to allow the driver to incorporate his or her own preference to plan a new route; and generating an optimized new route according to the driver'"'"'s preference. - View Dependent Claims (10, 11, 12, 13, 14, 15)

16. A route planning apparatus for multiple waypoints or points-of-interests (POIs), comprising:
-
a display unit, a plurality of input buttons adapted to accept user instructions; a computation unit adapted to provide routing information by calculating and comparing the distance of an existing route and the distance of a new route; and a route planning processor programmed to produce at least two routes, wherein the new route is produced according to new waypoint or POI added by the driver to the existing route. - View Dependent Claims (17, 18, 19)
