1. A navigation system used for a vehicle, the system comprising:
- map data acquisition means for acquiring map data to calculate a guiding route and perform route guidance;
acceptance means for accepting information from a user;
notification means for notifying the user; and
control means includingfirst routing means for calculating using the map data a first guiding route from a start point to a target region, which is obtained based on first information the first information being accepted by the acceptance means from the user,second routing means for(i) causing, while approaching the target region via the first guiding route, the notification means to prompt the user to input second information for specifying a destination,(ii) specifying a destination, based on the second information from the user, accepted by the acceptance means, and(iii) re-calculating after calculating the first guiding route, using the map data, a second guiding route to the specified destination, andguidance means for providing route guidance by causing the notification means to notify the user of the first guiding route and the second guiding route,the first routing means being further configured tocause the acceptance means to accept a visit purpose,cause the notification means to notify the user of target regions, the target regions being notified in descending order of distribution densities of facilities corresponding to the accepted visit purpose when there are plural target regions,cause the acceptance means to accept, from the user, third information for specifying one of the target regions which were notified, andcalculate the first guiding route to the target region specified based on the third information.

Abstract
There is a need for providing a navigation system that enhances the freedom of settling time points to determine a destination. The system prompts a user to input only information needed for determining a target region (e.g., a region including several tourist spots or a region including several ski resorts) at a departure time. The system prompts a user to input information needed for determining a specific destination (e.g., a specific tourist spot, or a specific ski resort) halfway through the target region. Accordingly, the user need not determine a specific destination at the departure time.

7. A method for performing route guidance in a navigation system, the method comprising:
-
accepting from a user, first information and a visit purpose; calculating, using map data, a first guiding route from a start point to a target region, which is obtained based on the first information from the user; notifying the user of the first guiding route and of target regions, the target regions being notified in descending order of distribution densities of facilities corresponding to the accepted visit purpose when there are plural target regions; accepting, from the user, third information for specifying one of the target regions which were notified; calculating the first guiding route to the target region specified based on the third information; prompting the user, while approaching the target region via the first guiding route, to input second information for specifying a destination; accepting the second information from the user; specifying a destination, based on the second information from the user; re-calculating after calculating the first guiding route, using the map data, a second guiding route to the specified destination; and notifying the user of the second guiding route. - View Dependent Claims (18)

8. A navigation system used for a vehicle, the system comprising:
-
a map data acquisition unit configured to acquire map data to calculate a guiding route and perform route guidance; an acceptance unit configured to accept information from a user; a notification unit configured to notify the user; and a control unit including a first routing unit configured to calculate, using the map data, a first guiding route from a start point to a target region, which is obtained based on first information from the user, the first information being accepted by the acceptance unit, a second routing unit configured to (i) cause, while approaching the target region via the first guiding route, the notification unit to prompt the user to input second information for specifying a destination, (ii) specify a destination, based on the second information from the user, accepted by the acceptance unit, and (iii) re-calculate, after calculating the first guiding route, using the map data a second guiding route to the specified destination, and a guidance unit configured to provide route guidance by causing the notification unit to notify the user of the first guiding route and the second guiding route, the first routing unit being further configured to cause the acceptance unit to accept a visit purpose, cause the notification unit to notify the user of target regions, the target regions being notified in descending order of distribution densities of facilities corresponding to the accepted visit purpose when there are plural target regions, cause the acceptance unit to accept, from the user, third information for specifying one of the target regions which were notified, and calculate the first guiding route to the target region specified based on the third information. - View Dependent Claims (19)
