The RAM 53 is a rewritable volatile memory for temporarily storing various data when each operation of the information providing server 50 is executed, and has a story information storage area 53a.

  The story information storage area 53a is an area for storing story information generated by the CPU 51. When the information providing server 50 receives a sightseeing route proposal request from the navigation device 10, the CPU 51 executes a sightseeing route proposal process, which will be described later with reference to FIG. 4, and a predetermined range from the current position of the vehicle on which the navigation device 10 is mounted. One or more stories are generated based on the chronology of historical persons most common to each tourist place included (for example, within 50 km). Then, for each story, the CPU 51 generates story information that summarizes the sightseeing route information that sets the order of the sightseeing places that are routed according to each story, and related information related to the story, and the story information is stored in the story. The information is stored in the information storage area 53a (see S52 in FIG. 4).

  In addition, when the information providing server 50 receives a story information transmission request from the navigation device 10, the information providing server 50 executes a sightseeing route transmission process, which will be described later with reference to FIG. 6, and stores the story information stored in the story information storage area 53a. The story information indicated by the story information transmission request is transmitted to the navigation device 10 from the inside. As a result, the navigation device 10 displays the sightseeing route included in the story information on the LCD 18 based on the story information transmitted from the information providing server 50 and proposes it to the vehicle occupant, and also indicates the sightseeing route. Route guidance to each tourist location in the order in which

  The HDD 54 is a rewritable magnetic disk that stores various programs executed by the CPU 51 such as an OS and application programs and various settings. A control program 54 a that executes the sightseeing route proposal process shown in the flowchart of FIG. 4 and the sightseeing route transmission process shown in the flowchart of FIG. 6 is stored in the HDD 54.

  The HDD 54 also stores a sightseeing place database 54b and a chronological database 54c. The tourist place database 54b is a database in which information on a plurality of tourist places is registered. In each tourist location, the name and location information (latitude and longitude information) of the tourist location are registered, and historical persons related to the tourist location are registered.

  The CPU 51 receives the tourist route proposal request from the navigation device 10 to execute the tourist route proposal process shown in FIG. 4, and based on the vehicle location information received together with the tourist route proposal request, the vehicle 51 Sightseeing places included in a predetermined range (for example, within 50 km) from the current location are determined and extracted from the location information of each sightseeing place registered in the sightseeing place database 54b (see S42 in FIG. 4).

  In addition, the CPU 51 confirms a related historical person from the registered contents of the tourist place database 54b for each tourist place included in the predetermined range from the current location of the vehicle extracted from the tourist place database 54b. The historical person most common to the place is extracted (see S43 in FIG. 4). As a result, the CPU 51 can extract the person most closely related to the current location of the vehicle, obtain the extracted chronological table of historical persons from the chronological database 54c described below, and determine the year. One or more stories are created based on the contents of the events described in the table.

  The chronological database 54b is a database in which a chronological table in which events (events) related to a person are described in chronological order for each person is registered. Also, in the chronological database 54b, for some events described in each chronological table, sub-event information describing in detail the event by further dividing the event is also registered. Yes.

  Here, the details of the chronological database 54c will be described with reference to FIG. FIG. 2A is a schematic diagram schematically showing an example of the contents of a chronological table (Kenshin Uesugi) registered in the chronological database 54c, and FIG. 2B is registered in the chronological database 54c. It is the schematic diagram which showed typically an example of the content of the subevent information (Nobunaga siege network).

  As shown in FIGS. 2A and 2B, the chronological table and the sub-event information are each composed of an “event” item and a “location” item. The “event” item is an item describing the contents of various events that occurred in relation to the historical figures shown in this chronological order, in the order in which the events occurred, and indicates the year (year) in which the event occurred It consists of a “year” sub-item and a “content” sub-item describing the content of the event.

  The “Location” item is an item that describes a sightseeing place related to the event described in the “Event” item. Among the events described in the “Event” item, there is a sightseeing place related to the event. If there is something to do, the name (or location information) of the sightseeing place is described in the “place” item in a form corresponding to the event.

  In the sub-event information, as shown in FIG. 2B, one event of the chronological table (in this example, “Nobunaga siege network”) is further divided and the contents of the event are described. Thus, the CPU 51 refers to only the chronology in which the contents of the event are roughly described, and generates a story based on the contents of the event described in the chronology, while the sub-event information is stored in the chronology database 54c. If there is an event prepared for, a story centered on the event described in detail in the sub-event information can be created.

  That is, the CPU 51 extracts the historical person most common to the sightseeing places included in the predetermined range from the current location of the vehicle, that is, extracted most recently in the vicinity of the current location of the vehicle, extracted by executing the sightseeing route proposal process shown in FIG. When a chronology of a person with connection is acquired from the chronology database 54c, based on the acquired chronology, first, a story that covers the events described in the entire chronology in the order of occurrence of the event is generated ( (See S45 in FIG. 3). As a result, it is possible to generate story information in which a sightseeing route for traveling around a tourist place related to a historical person in association with the life of the person is set.

  Further, if there is a highly related event in the acquired chronology, the CPU 51 collects the highly related events in the order of occurrence and generates a story (see S46 and S47 in FIG. 3). For example, in the example of FIG. 2, among the events related to Kenshin Uesugi, the battle of the first Kawanakajima to the battle of the fifth Kawanakajima is recognized as a particularly relevant event. A story that summarizes the battle of the fifth river Nakajima is generated. In this way, by gathering events that are particularly relevant and generating a story, a sightseeing route that circulates around tourist spots related to events that are highly relevant among historical places related to historical figures It is possible to generate story information set with.

  Furthermore, when there is an event for which sub-event information is prepared in the chronological database 54c in the acquired chronology, the CPU 51 refers to the sub-event information and is described in the sub-event information. A story is created by collecting each event in the order of occurrence centering on the event (see S48 and S49 in FIG. 3). For example, in the example of FIG. 2, since the sub-event information is prepared in the chronological database 54c for the “Nobunaga siege network”, the events described in the sub-event information for the “Nobunaga siege network” are summarized. A story is generated.

  In this way, by generating a story based on an event that is a more detailed one event, the tour circulates around a tourist spot related to one event among tourist spots related to historical figures. Story information that sets a sightseeing route can be generated.

  The CPU 51 also creates other stories when other stories can be created based on the chronological table.

  Then, after creating a story, the CPU 51 creates story information corresponding to each story for each story. The generation of this story information is performed by first setting the order of passing tourist spots for each story according to each story.

  Specifically, all the sightseeing places corresponding to each event gathered in the story corresponding to the story information to be generated are specified from the “place” item of the chronological database 54c, and the predetermined location is determined from the current location of the vehicle among the sightseeing places. It is determined as a place that should be routed through a sightseeing place included in the range. Then, the tourist places determined to be routed are arranged according to the order of events organized in the story (that is, the order of occurrence of the events), and each tourist place is routed according to the order. The order is set as a sightseeing route (see S51 in FIG. 3).

  Then, the CPU 51 adds related information, which is the content of the event included in the story, information related to the event, or related information that is information about the person who created the story to the tourist route information of the set tourism route. To generate story information. Such related information is generated from the chronological database 54c.

  That is, as the related information that is the content of the event included in the story, the contents described in the “content” sub-item of the “event” item of the chronology and sub-event information that is the basis of the story are used as they are. As information related to an event, the content described in the “content” sub-item of the “event” item of the sub-event information provided for the event is used.

  On the other hand, the information described in the “Content” sub-item of the event that is not included in the story among the events described in the chronology of the person is used as the information related to the person who created the story. In addition, if the name of another person is described in the event described in the chronology of the person, the “content” sub-item of the “event” item described in the chronology of the other person The content is used.

  At this time, the CPU 51 determines whether each piece of related information to be added to the story information is related information related to a tourist place that is routed as a tourist route, and as a result, relates to a tourist place that is routed as a tourist route. If it is related information, the related information is added to the story information in association with the related sightseeing place. On the other hand, in the case of other related information, the location associated with the event that is the basis of the relevant information is read from the “place” item of the chronological database 54c, and the location information (latitude and longitude) of the location is read. Information) is associated with the related information and added to the story information.

  The CPU 51 stores each piece of story information generated in this way in the story information storage area 53a. Then, by receiving a story information transmission request from the navigation device 10, the CPU 51 executes a sightseeing route transmission process (see FIG. 6), reads the story information specified in the transmission request from the story information storage area 53a, It transmits to the navigation apparatus 10. As a result, the navigation device 10 can propose a sightseeing route and guide the route to each sightseeing location based on the story information, and can display related information on the LCD 18 as appropriate.

  In addition, in the addition of related information to story information, all event contents related to a sightseeing place that is routed as a sightseeing route are added as related information, while related information of other events is appropriately selected and added. You may make it do. Thereby, in the navigation device 10, related information that is not related to a sightseeing place that is routed as a sightseeing route is displayed on the large number of LCDs 18, and it is possible to prevent the passenger from being provided with information more than necessary.

  Returning to FIG. 1, the description will be continued. The communication control device 55 is a circuit that transmits and receives various data to and from the wireless communication network 70 provided by the mobile phone operator. The information providing server 50 is accessed by the communication control device 55 from the navigation device 10 connected to the wireless communication network 70, receives a request for a sightseeing route proposal and a transmission request for story information from the navigation device 10, and receives these requests. In response, the story list and story information are transmitted to the navigation device 10.

  Next, with reference to FIGS. 3 to 6, each process executed by the CPU 11 in the navigation device 10 and the CPU 51 in the information providing server 50 will be described. First, FIG. 3 is a flowchart showing sightseeing route guidance processing executed by the CPU 11 in the navigation device 10. In this sightseeing route guidance process, a sightseeing route proposal request is transmitted to the information providing server 50, and the sightseeing route included in the story information is displayed on the LCD 18 according to the story information generated by the information providing server 50 in response to the request. When the sightseeing route display key 20a is operated in the process of displaying the above and suggesting it to the vehicle occupant and guiding the route to each sightseeing place in the order indicated by the sightseeing route, the CPU 11 executes the processing. .

  In this sightseeing route guidance process, first, position information of the current location of the vehicle is acquired from the current location detection device 15 (S11), and then it is determined whether or not the current location of the vehicle is the usual activity area (S12). . As described above, the navigation device 10 records the vehicle travel history (vehicle position information for each hour) and stores it in the HDD 14. In the process of S12, the vehicle travel history and S11 are used. The determination is made by comparing the acquired position information of the current location of the vehicle.

  If it is determined that the area is the normal activity area as a result of the process of S12 (S12: Yes), it is not necessary to provide a tourist route or guide the route to the passenger, so the tourist route guidance process is performed as it is. finish. In this case, the sightseeing route guidance process may be terminated after displaying a message on the LCD 18 notifying that the area is a normal activity area.

  On the other hand, if it is determined as a result of the processing of S12 that the area is not the usual activity area (S12: No), it is then determined whether or not the current location of the vehicle is a tourist spot (S13). In the road map database 14a of the HDD 14, information indicating whether or not each place is a sightseeing spot is added to the map information. In the process of S13, the position of the current location of the vehicle acquired by the process of S11. The determination is made by confirming from the map information in the road map database 14a whether or not the place indicated by the information is a sightseeing spot.

  If it is determined as a result of the processing of S13 that it is not a tourist spot (S13: No), it is not necessary to suggest a tourist route or guide the route to the occupant, so the tourist route guidance processing is terminated as it is. In this case, the sightseeing route guidance process may be terminated after displaying a message on the LCD 18 notifying that it is not a sightseeing spot.

  On the other hand, if it is determined as a sightseeing spot as a result of the processing of S13 (S13: Yes), then the tourist route proposal request is provided together with the location information of the current location of the vehicle acquired by the processing of S11. The communication control circuit 16 is controlled to transmit to the server 50 (S14), and the process proceeds to S15. Thereby, the sightseeing route proposal request is transmitted to the information providing server 50 through the base station 60 and the wireless communication network 70 together with the position information of the current location of the vehicle.

  Then, in the information providing server 50, the tourist route proposal process shown in FIG. 4 is executed by the CPU 51 by receiving this tourist route proposal request, and the story generated based on the person most closely related to the current location of the vehicle. Each time, the route information that passes through the sightseeing place according to the story and the story information that summarizes the related information about the story are generated, and the story list that shows the outline of the story is generated. Sent to.

  Here, with reference to FIG. 4, the sightseeing route proposal process performed by CPU51 in the information provision server 50 is demonstrated. FIG. 4 is a flowchart showing the sightseeing route proposal process.

  In this sightseeing route proposal process, first, positional information of the current location of the vehicle transmitted from the navigation device 10 together with the sightseeing route proposal request is received (S41), and a predetermined range from the current location of the vehicle indicated by the received positional information. A sightseeing place included in (for example, within 50 km) is determined and extracted from position information of each sightseeing place registered in the sightseeing place database 54b (S42).

  Next, for each sightseeing place extracted by the processing of S42, the related historical person is confirmed from the registered contents of the sightseeing place database 54b, and the historical person most common to each sightseeing place is extracted. (S43). Thereby, the person most closely related to the current location of the vehicle is identified.

  Then, a chronological table of historical persons extracted by the process of S43 is acquired from the chronological database 54c (S44), and a story is generated from the acquired chronology by the processes of S45 to S50. That is, the process for S45 to S50 generates a story for the person most closely related to the current location of the vehicle.

  First, in the process of S45, a story that covers events described in the entire chronology in the order of occurrence of the events is generated from the acquired chronology (S45). As a result, a story that summarizes the life of the person most related to the current location of the vehicle is generated.

  Next, it is determined whether or not there is a highly related event in the chronological table acquired by the processing of S44 (S46), and if there is a highly related event in the chronological table (S46: Yes), A highly relevant event is collected in the order of occurrence and a story is generated (S47). As a result, a story is generated that is centered around events that are particularly relevant to the person most closely related to the current location of the vehicle. In this case, there is a high possibility that characteristic events are collected for the person, and a story approaching the core of the person can be generated.

  Furthermore, after the process of S47, or when it is determined that there is no strongly related event in the chronological table by the process of S46 (S46: No), the year is included in the chronological table acquired by the process of S44. It is determined whether or not there is an event for which sub-event information is prepared in the table database 54c (S48). If there is an event for which sub-event information is prepared (S48: Yes), the chronological database 54c is used. With reference to the sub-event information, a story is created in which each event is collected in the order of occurrence centering on the event described in the sub-event information (S49). As a result, a story that is particular to one event among the events of the person most closely related to the current location of the vehicle is generated.

  In addition, after the process of S49 or when it is determined that there is no event for which sub-event information is prepared by the process of S48 (S48: No), whether or not another story can be created based on the chronological table. If it can be created, another story is created (S50).

  In this way, by creating various stories, various sightseeing routes can be proposed to the passengers of the vehicle on which the navigation device 10 is mounted.

  After a story is generated by the processes of S45 to S50, story information corresponding to each story is generated for each generated story by the processes of S50 and S51.

  First, for each generated story, a sightseeing route indicating the route order of the sightseeing places to be routed according to the contents of each story is set (S51). That is, the sightseeing place corresponding to each event included in the story is specified from the “place” item of the chronological database 54c, and the place to be routed through the sightseeing place included in the predetermined range from the current location of the vehicle is determined. Then, the tourist places are arranged in accordance with the order of occurrence of the events summarized in the story, and the route order of each tourist place is set as a tourist route so as to pass through each tourist place in accordance with the order. At this time, the approximate time required for the sightseeing route is also calculated.

  Then, for each story, with respect to the sightseeing route information of the sightseeing route set by the processing of S51, the contents of the event included in the story, information related to the event, or information about the person who is the basis of the creation of the story Certain related information is added to generate story information, and the story information is stored in the story information storage area 53a (S52).

  At this time, as described above, if each piece of related information to be added to the story information is related information related to a sightseeing place that is routed as a sightseeing route, the related information is added to the story information in association with the relevant sightseeing place. To do. On the other hand, in the case of other related information, the position information (latitude and longitude information) of the place associated with the event that is the basis of the related information is specified from the chronological database 54c, and the position information is Add to the story information in association with the related information.

  Note that the story information stored in the story information storage area 53a by the processing of S52 is, as described above, transmission of a sightseeing route which will be described later with reference to FIG. 6 when a request for acquiring story information is received from the navigation device 10. Through the processing, story information indicated by the acquisition request is read out and transmitted to the navigation device 10.

  Next, a story list is generated in which the outline of each story generated by the processes of S45 to S50 is listed together with the approximate required time calculated in the process of S51 (S53). And the produced | generated story list is transmitted to the navigation apparatus 10 (S54), and this sightseeing route proposal process is complete | finished. By receiving this story list, the navigation device 10 can display the contents of the list on the LCD 18 and execute a process of receiving an instruction of a desired story from a vehicle occupant.

  Here, in the sightseeing route proposal process, a sightseeing route corresponding to each story is set by the process of S51 based on each story generated by the processes of S45 to S50.

  For example, if the story of the most relevant event is generated from the chronology of the person most closely related to the current location of the vehicle in the process of S47, the related route is selected as the sightseeing route corresponding to the story. The order of passing through each tourist spot is set along a story that is organized around strong events. The navigation device 10 proposes a sightseeing route to each sightseeing place in the set order to the occupant of the vehicle, and if the occupant follows the sightseeing route by performing route guidance, , You can visit each tourist place with interest while feeling the relevant events along the story.

  In particular, the story generated by the processing of S47 is highly likely to be a collection of characteristic events in the historical person, and is likely to be a story approaching the core of the person. Therefore, if the occupant patrols each sightseeing place according to the sightseeing route generated based on the story approaching the core of the person, the passenger will be interested in feeling the story close to the core of the historical person. You can go around each tourist place with

  In addition, when the story is generated by collecting the events for which sub-event information is prepared from the chronology of the person most closely related to the current location of the vehicle by the processing of S49, as a sightseeing route corresponding to the story Then, the order of passing through each tourist place is set along the story gathered around the event for which the sub-event information is prepared. The navigation device 10 proposes a sightseeing route to each sightseeing place in the set order to the occupant of the vehicle, and if the occupant follows the sightseeing route by performing route guidance, You can visit each sightseeing spot with interest while making one event feel deeply along the story.

  In particular, since the story generated by the processing of S49 is a story generated by sticking to one event among the historical figures, if the occupant follows the sightseeing route indicated in the sightseeing route information of the story, , It is possible to go around each tourist place with interest while making the crew feel the commitment to one event deeply.

  Returning to FIG. 3, the explanation of the sightseeing route guidance process executed by the CPU 11 in the navigation device 10 is continued from the process of S <b> 15. In the process of S15, the timer function of the timer circuit 11a is started (S15). In this processing, after transmitting the sightseeing route proposal request to the information providing server 50 by the processing of S14, it is determined whether or not a response from the information providing server 50 to the sightseeing route proposal request is within a predetermined time. This is for determination by the processing of S17.

  Then, it is determined whether there is a response from the information providing server 50 based on the state of the communication control device 16 (S16). If there is no response from the information providing server 50, the timer function of the time measuring circuit 11a by the process of S15 After the start of the operation, it is determined from the state of the time measuring circuit 11a whether or not a predetermined time has elapsed (S17).

  As a result, if the predetermined time has not elapsed (S17: No), the process returns to S16, and it is determined again whether or not there is a response from the information providing server 50. On the other hand, if the predetermined time has passed as a result of the processing of S17 (S17: Yes), the destination candidate cannot be provided from the information providing server 50 due to communication or a failure in the information providing server 50. And the process proceeds to S25. In the process of S25, a “timeout error” is displayed on the LCD 18 (S25), and this sightseeing route guidance process is terminated. By displaying the timeout error, it is possible to make the occupant recognize that there is a problem in data transmission / reception with the information providing server 50.

  On the other hand, if it is determined that there is a response from the information providing server 50 as a result of the processing of S16 (S16: Yes), the story list transmitted from the information providing server 50 in response to the sightseeing route proposal request is received. Then, the received story list is displayed on the LCD 18 (S19), and the process proceeds to S20.

  Here, with reference to FIG. 5, the display content of the story list displayed on the LCD 18 in the navigation apparatus 10 will be described. FIG. 5 is a schematic diagram schematically showing a display example of the story list.

  As shown in FIG. 5, the CPU 11 extracts the outline of each story included in the story list (in the example of FIG. 5, “Life of Kenshin Uesugi”, “Battle of Kawanakajima”, “Nobunaga Siege”). On the left side of the screen of the LCD 18, the contents of the extracted outlines are displayed in order from top to bottom. Further, as described above, the story list includes the approximate required time for the sightseeing route set for each story (see S51 in FIG. 4), and the CPU 11 calculates the approximate required travel route for each story. After extracting the time, the approximate required time is displayed on the right side where the outline of the corresponding story is displayed.

  Here, the outline of each story displayed on the LCD 18 is surrounded by a rectangular frame for each story, and a range surrounded by the rectangular frame is buttoned (hereinafter, this button is referred to as “story”). Button "). The occupant determines the story to be selected from the outline of the story displayed on the LCD 18 and the estimated required time, and indicates the story button on which the outline of the story to be selected is displayed via the touch panel 19 with an indicator. A desired story can be selected and story information corresponding to the story can be received from the information providing server 50.

  Returning to FIG. 3, the description of the sightseeing route guidance process is continued from the process of S20. In the process of S20, it is determined whether or not one story is selected from the story list displayed on the LCD 18 when a story button is instructed by the occupant via the touch panel 19 (S20). While one story is not selected (S20: No), the process of S20 is repeatedly executed, and the process is waited until the selection is performed.

  In addition, while the process of S20 is repeatedly performed, based on a passenger | crew's instruction | indication, you may complete | finish a sightseeing root guidance process. For example, when the story list is displayed on the LCD 18 by the process of S19, an “end” button is also displayed on the LCD 18 and the “end button” instruction operation by the occupant is performed in the branch of S20: No. If detected, the sightseeing route guidance process may be terminated after the display of the story list is interrupted.

  On the other hand, if it is determined that one story has been selected by the occupant as a result of the process of S20 (S20: Yes), a transmission request for story information corresponding to the selected story is transmitted to the information providing server 50. The communication control circuit 16 is controlled (S21), and the process proceeds to S22. As a result, the story information transmission request is transmitted to the information providing server 50 via the base station 60 and the wireless communication network 70.

  Upon receiving the story information transmission request from the navigation device 10, the information providing server 50 executes a sightseeing route transmission process (see FIG. 6) by the CPU 51, and stores the story information stored in the story information storage area 53a. The story information indicated by the story information transmission request is transmitted to the navigation device 10.

  Here, with reference to FIG. 6, the sightseeing route transmission process performed by CPU51 in the information provision server 50 is demonstrated. FIG. 6 is a flowchart showing the sightseeing route transmission processing.

  In this sightseeing route transmission process, first, the story information to be transmitted specified by the transmission request of the story information received from the navigation device 10 is identified (S61), and the identified story information is read from the story information storage area (S61). S62). Then, the read story information is transmitted to the navigation device 10 (S63), and this sightseeing route transmission process is terminated.

  Thereby, story information corresponding to the story selected by the occupant is transmitted to the navigation device 10. Based on the story information, the navigation device 10 proposes a sightseeing route and guides the route of each sightseeing place.

  Returning to FIG. 3, the description of the sightseeing route guidance process executed by the CPU 11 in the navigation device 10 is continued from the process of S <b> 22. In the process of S22, the operation of the timer function of the timer circuit 11a is started (S22). In this process, after transmitting a transmission request for story information to the information providing server 50 by the process of S21, it is determined whether a response from the information providing server 50 to the transmission request for story information is within a predetermined time. This is for determination by the processing of S23 and S24.

  Then, it is determined whether or not there is a response from the information providing server 50 based on the state of the communication control device 16 (S23). If there is no response from the information providing server 50, the timer function of the time measuring circuit 11a by the process of S22. After the start of the operation, it is determined from the state of the time measuring circuit 11a whether or not a predetermined time has elapsed (S24).

  As a result, if the predetermined time has not elapsed (S24: No), the process returns to the process of S23, and it is determined again whether or not there is a response from the information providing server 50. On the other hand, if the predetermined time has passed as a result of the processing in S24 (S24: Yes), the destination candidate cannot be provided from the information providing server 50 due to communication or a failure in the information providing server 50. Is determined, a “timeout error” is displayed on the LCD 18 (S25), and this sightseeing route guidance process is terminated. By displaying the timeout error, it is possible to make the occupant recognize that there is a problem in data transmission / reception with the information providing server 50.
