The request is transmitted to the navigation server 200 (step SA-9).

  In Step SA-9, the movement method change request may further include a designated time in which either the departure time or the arrival time is fixed in a part of the guide route.

  Here, an example in which the movement method change request further includes a designated time in which either the departure time or the arrival time is fixed in a part of the guide route will be described with reference to FIG.

  FIG. 5 is a diagram illustrating screen transition when the travel method (transportation means) is changed from walking to automobile in the section closest to the departure place side. FIG. 5A shows a search result screen displaying route guidance information including at least a guidance route. The search result screen provides an interface (FIGS. 5 (i) and (ii)) that allows the user to arbitrarily select a movement method in each section. The interface may be in an icon format or a rollover format suitable for touch panel operation. FIG. 5B shows the case where the arrival time is the end point, and FIG. 5C shows the case where the departure time is the starting point.

  For example, when an output screen as shown in FIG. 5A is displayed as a search result of the guide route, the user selects the button (i) in FIG. 5A (ie, the arrival time (eg, “16 When the “moving means change request button” which fixes “time 13 minutes”) as the designated time is selected, the moving method change request transmission unit 102e is part of the guide route from “A building” to “B station”. 5 is designated to be changed to “car” indicated by (iv) in FIG. 5B, and the arrival time “16:00” indicated by (v) in FIG. A moving means change request including a designated time with “13 minutes” fixed is transmitted to the navigation server 200. On the other hand, when the user selects the button (ii) in FIG. 5A (that is, the “movement means change request button” that fixes the departure time (for example, “16:07”) as the designated time). The moving method change request transmitting unit 102e indicates the moving means “walking” used for a part of the guide route from “A building” to “B station” by “Vehicle” indicated by (vii) in FIG. , And a moving means change request including a designated time in which the departure time “16:07” indicated by (vi) in FIG. 5C is fixed is transmitted to the navigation server 200. Here, (viii) in FIG. 5 (c) is the departure / arrival time at station B (“16:09” changed with the departure time “16:07” indicated by (vi) in FIG. 5 (c). Arrival, departure at 16:10 "). In the present embodiment, either the departure time or the arrival time is not fixed as the designated time, but another time (for example, the current time) may be fixed as the designated time.

  In the present embodiment, when a route search is requested (that is, when the route search condition is transmitted in step SA-2), the departure time is specified in advance in the route search condition or the arrival time is specified. Depending on whether or not the “moving means change request button” (the button (i) or (ii) in FIG. 5A) is pressed, the moving means displayed may be limited. For example, when a search request is made in the state where the departure time has already been specified in the route search condition in step SA-2, a “movement means change request button” (ie, a button for fixing the arrival time as the specified time (FIG. 5). When a button on the left side of (a) (i) or the like) is pressed, a moving means (for example, a car) whose departure time is delayed may be disabled. As an example, when a plurality of routes are acquired in advance, it is not necessary to display other routes that do not need to change the departure time, and when the travel method change request transmission unit 102e requests a search for a route after the change. The search request may be made after fixing the departure time.

  Furthermore, in the present embodiment, depending on whether the route to be corrected is a route closer to the starting point or a route closer to the destination in the entire route, (ii) in FIG. Only the “movement means change request button” on the departure time side (right side) (that is, a button for fixing the departure time as a designated time) can be selected, or the arrival time such as (i) in FIG. Control may be performed so that only the “moving means change request button” on the side (left side) (that is, a button for fixing the arrival time as a designated time) can be selected. For example, when changing the moving means of the route closer to the departure place (for example, the route from building A to station B in FIG. 5A) of the entire route, the “moving means change request button” on the arrival time side. (Ie, a button for fixing the arrival time as a designated time) can be selected, and when changing the route of the route closer to the destination (for example, from station L to home in FIG. 5A), the departure time side Only the “movement means change request button” (that is, a button for fixing the departure time as a designated time) may be selectable.

  In Step SA-9, the movement method change request may specify a plurality of movement methods obtained by dividing one movement method used in a part of the guide route.

  Here, with reference to FIG. 6, an example in which the movement method change request designates a plurality of movement methods obtained by dividing one movement method used in a part of the guide route will be described.

  For example, when an output screen as shown in FIG. 6A is displayed as a search result of the guide route, the user selects the button (i) in FIG. 6A (that is, a part of the guide route (for example, , “Guide route from“ I station ”to“ L station ”” is divided into a plurality of movement methods (for example, “train” and “walk”). When the “change station button to get off” is selected, an output screen including a list of stations as shown in FIG. 6B is displayed. Then, for example, when the user selects to change “L station” shown in (ii) of FIG. 6B to “K station” (that is, the station where the “L station” gets down to “K station”) The movement method change request transmitting unit 102e receives one movement method (for example, a guide route from “I station” to “L station”) (for example, a guide route from “I station” to “L station”). A plurality of movement methods (for example, “I station” to “K station”) are divided into “trains”, and the movement method from “K station” to “L station” is “walk”. , Etc.) is transmitted to the navigation server 200. In the present embodiment, the division means that a part of the guide route that moves by a single moving method is changed to move by a plurality of moving methods. For example, it means a change such as dividing “train” into “train + walk”.

  Thereby, in this embodiment, for example, when a user (user) gets off in the middle of a set train ride section and wants to walk from there, the set section is divided into two parts. It is possible to change the moving method of the next section to the part by walking. Further, when the user determines that it is better to walk (or use a taxi or bus) because the inside of the train is crowded, it is possible to save the trouble of searching again after getting off the train. At this time, the walking route (or taxi route or bus route) from the divided point to the destination has not been searched yet, so the search process is actually executed, but the return to the top screen and set the destination Since the process performed by the user, such as performing, can be omitted, the user can experience that labor has been reduced. That is, by making it possible to change the movement method of each section starting from the top search result screen, the level of screen transitions by user operations is reduced, so that the user's feeling of use can be improved.

  In Step SA-9, the movement method change request may specify one movement method obtained by combining a plurality of movement methods used in a part of the guide route.

  Here, with reference to FIG. 7, an example in which the movement method change request designates one movement method obtained by combining a plurality of movement methods used in a part of the guide route will be described.

  For example, when the output screen as shown in FIG. 7A is displayed as the search result of the guide route, the user selects the button (i) in FIG. 7A (that is, a part of the guide route (for example, , Combining a plurality of movement methods (for example, “walk” and “train”) used in “A building” to “I station” to one movement method (for example, “taxi”). When the “join button” is selected, a movement method selection screen as shown in FIG. 7B is displayed. For example, when one movement method “taxi” is selected by the user from the plurality of movement methods “other routes, buses, taxis, private cars” shown in FIG. The unit 102e combines a plurality of movement methods (for example, “walk” and “train”) used in a part of the guide route (for example, the guide route from “A building” to “I station”). A moving means change request for designating a moving method (for example, “Taxis” is set as the moving method from “A building” to “I station”) is transmitted to the navigation server 200. In the present embodiment, the term “combination” refers to changing a part of the guide route that moves by a plurality of movement methods so that the route moves by a single movement method. For example, it means a change such as combining “bus + walk” with “taxi”.

  Thereby, in this embodiment, for example, it is possible to respond to a user's request that a route that is a bus → walk is changed to a car at a time and the user wants to move by taxi. In addition, in order to deal with the difference in usage scenes due to the difference between taxis and private cars, for example, there was an input to change the travel method from the current position to the station to a car and to use a private car In some cases (for example, when using a private car to move from home to the station, or when using a private car to travel to public transport, etc.), unless the station has a parking lot, the current location → the nearest station It is possible to present the route with the car at the parking lot and the parking lot → the station on foot. In this case, since the number of sections increases as compared with the case of walking alone or the car alone, the section after the station is shifted downward as a display.

  Returning to FIG. 4, the movement method change request receiving unit 202d of the navigation server 200 transmits a part of the guide route (for example, the figure) transmitted from the terminal device 100 by the processing of the movement method change request transmitting unit 102e in step SA-9. Change of travel method for “A building” to “B station” shown in 3B (for example, change from “walk” travel method shown in FIG. 3B to “car” travel method shown in FIG. 3C) ) Is received (step SA-10). Further, in the present embodiment, the movement method change request receiving unit 202d may receive the information on the changed portion related to the guide route output by the terminal device 100 together with the movement method change request.

  When the movement method change request is received by the movement method change request receiving unit 202d in step SA-10, the control unit 202 of the navigation server 200 receives the movement method specified by the movement method change request (for example, FIG. It is determined whether or not the different route data corresponding to the “moving method of“ car ”shown in the figure is in the search result database 206b (step SA-11).

  In step SA-11, when it is determined by the processing of the control unit 202 of the navigation server 200 that there is no other route data corresponding to the designated movement method (step SA-11: No), the navigation server 200 The different route searching unit 202e determines the movement method (for example, FIG. 3C) specified by the movement method change request for a part of the guidance route (for example, the guidance route from “A building” to “B station” illustrated in FIG. 3B). The other route guidance information including at least another route data of the searched different route is searched using the network data stored in the network database 206a. Generate (step SA-12). In this manner, the different route search unit 202e specifies the affected section when the change request target moving means does not correspond to the moving means previously stored in the search result database 206b, and determines another route for a part of the guide route. Search again. Here, in step SA-12, the different route search unit 202e may store the generated different route guidance information in the search result database 206b. Thereafter, the process proceeds to Step SA-14.

  Here, in step SA-12, the different route search unit 202e determines the designated time (for example, departure time “16:00” shown in (vi) of FIG. 5C) included in the movement method change request for a part of the guide route. 07 ”or the arrival time“ 16:13 ”shown in (v) of FIG. 5B) (for example, (iv) and FIG. 5C of FIG. 5B). ) (Vii) (an automobile moving method) shown in (vii)) may be searched for. For example, as shown in FIG. 5B, when the different route search unit 202e fixes the arrival time “16:13” as the designated time, the time to arrive at “B station” is “16:13”. To search for another route. As a result, only the departure time “16:11” indicated by (iii) in FIG. 5B is changed, and the boarding time from “B station” to “home” is not changed. Further, as illustrated in FIG. 5C, when the departure time “16:07” is fixed as the designated time, the alternative route search unit 202e sets the departure time of “A building” to “16:07”. To search for another route. As a result, only the departure time “16:07” indicated by (vi) in FIG. 5C is fixed, and the subsequent transit times and arrivals indicated by (vii) and (ix) in FIG. The time is changed.

  In step SA-12, the separate route search unit 202e makes a request for changing the movement method for a part of the guide route (for example, the guide route from “I station” to “L station” shown in FIG. 6A). When using a plurality of designated movement methods (for example, "Train" movement method from "I station" to "K station", "Walk" movement method from "K station" to "L station") Another route may be searched. In this way, the different route search unit 202e sets the train section to the station (for example, “K station”) before the station (for example, “L station”) designated as the station where the current train is exited, and the remaining section (for example, “K station”) , The section from “K station” to “L station”) may be searched for another route when a plurality of movement methods (for example, “train” and “walk”) are used. That is, when the station (for example, “K station”) where the user gets off is designated by the user, the different route search unit 202e performs the route search again assuming that the station is off.

  In step SA-12, the separate route search unit 202e makes a request for changing the movement method for a part of the guide route (for example, the guide route from “A building” to “I station” shown in FIG. 7A). Another route may be searched when using one designated movement method (for example, “taxi”). In this way, the different route search unit 202e re-searches the route with the movement method (for example, taxi) selected on the movement method selection screen as shown in FIG. 7B.

  On the other hand, when it is determined in step SA-11 that there is another route data corresponding to the designated movement method by the processing of the control unit 202 of the navigation server 200 (step SA-11: Yes), that is, the navigation server. When there is another route data corresponding to the moving method specified by the moving method change request (for example, the moving method of “car” shown in FIG. 3C) in the search result database 206 b of 200, another route searching unit 202 e of the navigation server 200. Acquires the corresponding different route data from the search result database 206b, and generates different route guidance information including at least the different route data (step SA-13). As described above, the different route search unit 202e acquires the route result held in the search result database 206b when the change request target moving device corresponds to the moving device previously held in the search result database 206b. . Thereafter, the process proceeds to Step SA-14.

  Then, the different route guidance information transmission unit 202f of the navigation server 200 transmits the different route guidance information generated by the processing of the different route search unit 202e in Step SA-12 and Step SA-13 to the terminal device 100 (Step SA). -14). That is, the different route guidance information transmission unit 202f transmits the result of the re-search to the terminal device 100. Thereafter, the processing of the navigation server 200 ends.

  Then, the different route guidance information receiving unit 102f of the terminal device 100 receives the different route guidance information transmitted from the navigation server 200 by the processing of the different route guidance information transmitting unit 202f in step SA-14 (step SA-15). ). Here, in step SA-15, the different route guidance information receiving unit 102f may further store the received different route guidance information in the search result file 106a. In addition, when the existing another route guidance information is stored in the search result file 106a, the different route guidance information receiving unit 102f overwrites the existing different route guidance information with the existing different route guidance information. It may be stored.

  Then, the different route guidance information output unit 102g of the terminal device 100 outputs at least a part of the different route guidance information received by the processing of the different route guidance information reception unit 102f in step SA-15 via the output unit. (Step SA-16). That is, the different route guidance information output unit 102g performs route guidance based on the different route guidance information received from the navigation server 200. Here, in step SA-16, the different route guidance information output unit 102g obtains the current position information acquired by the processing of the current position information acquisition unit 102a, and the processing of the different route guidance information reception unit 102f in step SA-15. The route guidance may be executed by outputting at least part of the other route guidance information received by the output unit via the output unit. Further, the different route guidance information output unit 102g displays, for example, the different route data included in the different route guidance information and the current location information of the user of the terminal device 100 on the map data included in the different route guidance information. The superimposed display screen may be displayed on the display unit 114.

  Further, the different route guidance information output unit 102g may cause the display unit 114 to display a display screen based on the different route guidance information. For example, the different route guidance information output unit 102g includes different route data, transportation route information, transportation destination information, transportation route type, transportation route name, railway station included in the separate route guidance information. Name of boarding / exiting points such as bus stops, station exit information, transportation boarding location information, first departure, walking route, weather information, number of transportation transfers, time required for different routes, different A display screen based on display data such as toll data, route data, timetable data, map data, and / or TBT included in the guide data when using the route may be displayed on the display unit 114. Further, the different route guidance information output unit 102g may output the different route guidance information via the voice output unit 116. For example, the separate route guidance information output unit 102g may output, via the voice output unit 116, voice guidance data associated with a traveling direction or the like at a branch point on another route included in the separate route guidance information. Good. Then, the process of the terminal device 100 is complete | finished.

  Next, another example of the processing of the navigation system in the first embodiment will be described with reference to FIG.

  Here, FIG. 8 shows that another route data is held in the search result file 106a on the terminal device 100 side, and a part of the guide route is used for a part of the guide route using the different route data previously held in the search result file 106a. The process which performs a re-search is shown.

  In FIG. 8, the processing of Step SB-1 to Step SB-3 is the same as the processing of Step SA-1 to Step SA-3 of FIG.

  As shown in FIG. 8, in step SB-4, the guide route searching unit 202b of the navigation server 200 satisfies the route search condition received by the processing of the route search condition receiving unit 202a in step SB-3. A guide route that is a route to the destination (for example, a guide route from “A building” to “home” shown in FIGS. 3A to 3C) is searched using the network data stored in the network database 206 a and searched. Route guidance information including at least the guidance route data of the guidance route is generated (step SB-4). Here, in step SB-4, the guide route searching unit 202b may also search for another route when another travel method (for example, “automobile”) is used for a part of the searched guide route. Good.

  Then, the route guidance information transmission unit 202c of the navigation server 200 transmits the route guidance information generated by the processing of the guidance route search unit 202b in step SB-4 to the terminal device 100 (step SB-5). Here, in step SB-5, the route guidance information transmission unit 202c transmits the different route data of the different route searched by the processing of the guidance route search unit 202b in step SB-4 to the terminal device 100.

  And the route guidance information receiving part 102c of the terminal device 100 receives the route guidance information transmitted from the navigation server 200 by the process of the route guidance information transmission part 202c in step SB-5 (step SB-6). Here, in step SB-6, the route guidance information receiving unit 102c further stores the received route guidance information in the search result file 106a. Further, the route guidance information receiving unit 102f receives the different route data transmitted from the navigation server 200, and stores the received different route data in the search result file 106a of the terminal device 100. In addition, when the existing route guidance information and / or different route data is stored in the search result file 106a, the route guidance information receiving unit 102c uses the newly set route guidance information and / or different route data as the existing route guidance information and / or different route data. The route guidance information and / or other route data may be overwritten and stored.

  Here, in FIG. 8, the process of step SB-7 is the same as the process of step SA-7 of FIG.

  And the control part 102 of the terminal device 100 is a part of guidance route (for example, guidance route from "A building" to "B station" shown in FIG. 3B) input by the user via the input unit 118. A movement method change request for requesting a change in the movement method (for example, a change from the “walk” movement method shown in FIG. 3B to the “automobile” movement method shown in FIG. 3C) is accepted (step SB-8).

  Here, in step SB-8, the movement method change request is issued when a departure time (for example, a guide route from “A building” to “B station” shown in FIG. 5 (c) (vi) departure time “16:07”) or arrival time (for example, arrival time “16:13” shown in FIG. 5B (v)) It may further include a fixed designated time. In addition, the movement method change request is one movement method (for example, movement of “train”) used in a part of the guidance route (for example, the guidance route from “I station” to “L station” shown in FIG. 6). A plurality of movement methods (for example, “train” and “walk” movement methods) may be designated. In addition, the movement method change request includes a plurality of movement methods (for example, “train” and “trains” used in a part of the guidance route (for example, the guidance route from “A building” to “I station” shown in FIG. One movement method (for example, a “taxi” movement method) combined with a “walk” movement method) may be designated.

  When the control unit 102 of the terminal device 100 receives the movement method change request by the processing of the control unit 102 in step SB-8, the movement method designated by the movement method change request (for example, “ It is determined whether or not the different route data corresponding to the “mobile method” is present in the search result file 106a (step SB-9).

  In Step SB-9, when it is determined by the processing of the control unit 102 of the terminal device 100 that there is another path data corresponding to the designated movement method (Step SB-9: Yes), that is, the terminal device When there is another route data corresponding to the movement method specified by the movement method change request (for example, the movement method of “car” shown in FIG. 3C) in 100 search result files 106 a, the control unit 102 of the terminal device 100 Corresponding different route data is acquired from the search result file 106a, and different route guidance information including at least the different route data is generated (step SB-10). As described above, the control unit 102 of the terminal device 100 determines the route result held in the search result file 106a when the change request target moving means corresponds to the moving means held in the search result file 106a in advance. get. Thereafter, the process proceeds to Step SB-16.

  On the other hand, when it is determined in step SB-9 that there is no other route data corresponding to the designated movement method by the processing of the control unit 102 of the terminal device 100 (step SB-9: No), that is, the terminal device When there is no other route data corresponding to the movement method specified by the movement method change request (for example, the movement method of “car” shown in FIG. 3C) in 100 search result files 106 a, a movement method change request transmission of the terminal device 100 is transmitted. The unit 102e moves about a part of the guidance route (for example, the guidance route from “A building” to “B station” shown in FIG. 3B) input by the user via the input unit 118 in step SB-8. Navigation method change request for requesting change of method (for example, change from “walk” movement method shown in FIG. 3B to “automobile” movement method shown in FIG. 3C) And it transmits to the Activation server 200 (step SB-11).

  Here, in FIG. 8, the process of step SB-12 is the same as the process of step SA-10 of FIG.

  Then, when another route search unit 202e of the navigation server 200 receives the movement method change request transmitted from the terminal device 100 by the processing of the movement method change request reception unit 202d in step SB-12, a part of the guidance route For example (for example, the guide route from “A building” to “B station” shown in FIG. 3B), the moving method specified by the moving method change request (for example, the moving method of “automobile” shown in FIG. 3C) was used. The other route in the case is searched using the network data stored in the network database 206a, and another route guidance information including at least another route data of the searched other route is generated (step SB-13).

  Here, in step SB-13, the different route search unit 202e determines the designated time (for example, departure time “16:00” shown in (vi) of FIG. 5C) included in the movement method change request for a part of the guide route. 07 ”or the arrival time“ 16:13 ”shown in (v) of FIG. 5B) (for example, (iv) and FIG. 5C of FIG. 5B). ) (Vii) (an automobile moving method) shown in (vii)) may be searched for. Further, the different route search unit 202e performs a plurality of movements specified by the movement method change request for a part of the guidance route (for example, the guidance route from “I station” to “L station” shown in FIG. 6A). Search for another route when using the method (for example, “Train Station” to “K Station”, “Walk” to “K Station” to “L Station”). May be. Further, the different route search unit 202e performs one movement designated by the movement method change request for a part of the guidance route (for example, the guidance route from “A building” to “I station” shown in FIG. 7A). Another route when using a method (for example, “taxi”) may be searched. As described above, the different route search unit 202e changes the moving method transmitted from the terminal device 100 when the moving means to be changed does not correspond to the moving means held in advance in the search result file 106a of the terminal device 100. Based on the request, the affected section is specified, and another route is re-searched for a part of the guide route.

  Then, the separate route guidance information transmission unit 202f of the navigation server 200 transmits the separate route guidance information generated by the processing of the separate route search unit 202e in step SB-13 to the terminal device 100 (step SB-14). Thereafter, the processing of the navigation server 200 ends.

  Here, in FIG. 8, the process of step SB-15 is the same as the process of step SA-15 of FIG.

  Then, the different route guidance information output unit 102g of the terminal device 100 outputs at least a part of the different route guidance information received by the processing of the different route guidance information reception unit 102f in step SB-15 via the output unit. (Step SB-16). In step SB-16, the different route guidance information output unit 102g has another route data corresponding to the movement method designated by the movement method change request in the search result file 106a of the terminal device 100 (that is, the above “ In the case of “step SB-9: Yes”), at least a part of the different route guidance information including at least the different route data acquired from the search result file 106a by the processing of the control unit 102 of the terminal device 100 in step SB-10.
