Embodiment approach 1

[0119] FIG. 1 is a system configuration diagram showing an example of a route information display device according to this embodiment. This route information display device can be implemented as, for example, a car navigation system, or can be configured using a car navigation system host, a vehicle display, and a GPS (Global Positioning System: Global Positioning System) receiver.

[0120] The category input unit 1001 is, for example, a means for inputting a category which is a keyword for searching a destination. This category is an example of a classification of mobile destinations. The map information storage unit 1003 is a unit for storing facility information or map information. Based on the map information stored in the map information storage unit 1003, a plurality of travel destinations corresponding to the above categories are searched in the plurality of travel destination search units 1002, It is used as an input to the multiple destination input unit 1004 .

Embodiment approach 2

[0182] In the above-mentioned embodiment, a method of calculating a branch point on a route to a plurality of input destinations and controlling the display of information related to the destination using the branch point has been described. Way. For example, it is often the case that multiple travel destinations are retrieved, and when judging which destination to go to, the information up to the branch point is what the user cares about, and the next travel is determined according to the congestion situation or predicted arrival time destination. In addition, by comparing and displaying the information after the branch point, the final destination is determined, and the display method of these provided information is controlled by the branch point, so that information can be easily grasped without complicated operations.

[0183] In addition, in the above embodiment, the calculation of the branch point is, for example, searching for routes of a plurality of input destinatio...

Embodiment approach 3

[0243] In the above-mentioned second embodiment, the branch point is calculated using the travel history, and a method of controlling the display form of information using the branch point will be described below. When a plurality of travel destinations are retrieved, branch points of the plurality of travel destinations are calculated, and information is displayed based on the branch points, so that the user can grasp the information better. Moreover, the travel history is also considered, for example, based on the route stored in the travel history, the route of other travel destinations is searched again, and the branch point is calculated, so that the user can go to the travel destination from the branch point of the route that is usually used. . In addition, the calculation method of the branch point is, for example, calculating a plurality of routes to the destination, using the branch points in each route as the branch point candidates, and selecting the branch point fr...

Abstract

A route information display device is provided which calculates a branch point in routes to a plurality of inputted destinations, and uses the branch point to control information modes. A route information display device according to the present invention includes: a departure point input unit ( 1012 ) that detects a current location of the user; a multiple destination input unit ( 1004 ) that accepts input of a plurality of destinations; a route search unit ( 1005 ) that searches for respective routes from the current location to the plurality of destinations; a branch point calculation unit ( 1007 ) that calculates a branch point of the respective searched routes; and a route information display unit ( 1011 ) that displays information regarding routes to the branch point and information regarding routes beyond the branch point in different modes, wherein the route information display device supports easy comprehension of information by the user by calculating a branch point of a plurality of inputted destinations and providing information in consideration of the branch point.

Description

technical field [0001] The present invention relates to a moving destination display device for displaying a user's moving destination, and is particularly applicable to a moving destination display device, which is suitable for a mobile terminal such as a car navigation system (hereinafter referred to as car navigation). Background technique [0002] Conventionally, there is a device for inputting a keyword such as "restaurant" into a mobile terminal such as a car navigation system, and displaying information on destinations retrieved by the keyword (Patent Document 1). And, also have such a kind of device, promptly: input a movement destination, search for a plurality of routes of this movement destination, and the branch point in the plurality of routes and route of searching are displayed with simple diagram (patent document 2).
