NAVIGATION SYSTEMS AND ROUTE PLANNING METHODS THEREOF
First Claim
1. A route planning method for use in an electronic device, comprising:
- generating a planned route according to at least one destination by the electronic device;
performing a navigation process according to the planned route by the electronic device;
determining whether a route re-planning request has been generated;
determining a return point from the planned route when the route re-planning request has been generated, wherein the return point corresponds to a current position of the electronic device;
re-planning a partial route from the current position to the return point; and
navigating to the return point according to the partial route and proceeding with the navigation process from the return point to the destination according to the planned route.

Abstract
Route planning methods for navigating an electronic device are disclosed. The method includes the following steps. First, the electronic device generates a planned route according to at least one destination, and performs a navigation process according to the planned route. It is determined whether a route re-planning request has been generated. When the route re-planning request has been generated, a return point is determined from the planned route, wherein the return point corresponds to a current position of the electronic device. A partial route from the current position to the return point is determined. Navigating to the return point is performed according to the partial route and the navigation process proceeds from the return point to the destination according to the planned route.

17. A route planning method for use in an electronic device, comprising:
-
generating a planned route according to at least one destination by the electronic device; performing a navigation process according to the planned route by the electronic device; determining whether a route re-planning request has been generated; determining a return point that is a nearest point to a current position of the electronic device from the planned route when the route re-planning request has been generated; re-planning a partial route from the current position to the return point and reserving the planned route; and navigating to the return point according to the partial route and proceeding with the navigation process from the return point to the destination according to the planned route, wherein the partial route is a shortest route or a fastest route from the current position to the planned route.
