[0030] According to a first embodiment of the invention, the route finding device finds a route from a start point to an end point by employing options for the entire route, and then receives from the user a portion of the entire route and partial route options applied to this portion, Thus creating the entire path.

[0031] Figures 3A to 3C is a conceptual diagram of the path finding method according to the first embodiment of the present invention. If a start / end point is entered and "option 1" is entered, the pathfinding device does this by applying "option 1" to Figure 3A The entire path shown to find the entire path from the start point to the end point.

[0032] In addition, the route finding device receives a predetermined portion selected by the user from the entire route, which portion uses another option. Figure 3A A case where the parts selected by the user are A to B parts is shown. The user can select an unsatisfactory part or use another option from the wh...

Abstract

Disclosed is a method for finding a path in a navigation system. The method includes selecting a sectional path option for a specific section selected by a user from an entire section between a start point and an end point, and finding a path in the specific section according to the sectional path option and creating an entire path for an entire section by employing the path in the specific section. Accordingly, a sectional path option different from an entire path operation for an entire path is applied to a specific section desired by a user on an entire path to an end point from a start point, so that it is possible to efficiently apply an option desired by the user to path finding.

Description

technical field [0001] The present invention relates to a navigation system, more specifically, to a method for finding a route from a starting point to a destination (destination) in the navigation system. Background technique [0002] Generally, a navigation system has a function of setting user options so that the navigation system can find a route to a destination desired by the user when performing route finding. [0003] User options may include various route finding preferences, such as "highway preference", "shortest route", and "toll-free route preference", and the user may select a desired option from predetermined user options to find the route to the destination. Ideal path (ie, shortest or most efficient path). [0004] figure 1 is a conceptual diagram of traditional path-finding methods. refer to figure 1 , traditionally, a user enters a desired destination into a navigation system and selects an option (eg, "Option 1") for the enti...
