That is, the route search unit 11 acquires information necessary for the route search process from the road map information storage unit 21. Hereinafter, the map information and the road information are appropriately referred to as “road map information”.

  The road information may be different depending on the time and the traveling direction of the vehicle. Here, in the road information in this example, the length and passage time of each link are stored as route costs. In addition, the road information has a plurality of hierarchies. In this example, the road information is for neighborhood (stores all roads), for short distance (stores roads other than narrow streets), for medium distance (prefecture roads or more). Storage) and long-distance use (stores highways and national roads). In this case, for example, hierarchical information may be set for the nodes and links constituting the road information. Thereby, the road information which is the object of the route search can be properly used depending on the route search condition. That is, for example, when the distance from the current position to the destination is a long distance, the amount of road information existing between them is enormous, so the route search process is performed using the road information set for long distance. By doing so, the processing load of the route search unit 11 can be reduced.

  The POI information storage unit 22 is a storage medium that stores POI information indicating a guidance object. The POI information in this example can specify a POI-ID for uniquely identifying a guidance object such as a facility or resort, a name of the guidance object such as a facility (a POI name), and a position on a map.

  Here, the “event content” may be content indicating the content of the event, and may be document data or image data. Further, a configuration may be adopted in which a predetermined genre is selected and set according to the content of the event. In this example, a case will be described as an example where a character string that simply indicates the content of the event, such as “festival”, “fireworks display”, and “time service”, is set as the event content. In this example, the event content is set by the creator of the event information.

  The “related POI” may be any information that can identify POI information indicating a guidance object related to the event information. In this example, the POI name is registered in advance by the creator of the event information. The related POI may be automatically set from the event area in the event information and the position information in the POI information.

The action history storage unit 24 is a storage medium that stores a user's action history.
FIG. 4 is an explanatory diagram illustrating an example of a behavior history storage state in the behavior history storage unit 24. As shown in FIG. 4, the action history in this example includes trajectory information indicating a route traveled by the vehicle in the past, information search history, and use POI.

  Here, the “trajectory information” is information indicating a route traveled by the vehicle, and includes a link, a node, and an address that is input as a destination at the time of movement, when the address is input. The trajectory information may be stored when the vehicle travels continuously for a predetermined time.

  The “search history” is used when a search function of the navigation device (for example, a function for executing a general keyword search performed by accessing the Internet through the communication unit 60) according to a user operation is used. This is information indicating the search keyword used.

  The “used POI” is information indicating the POI used or registered as a “destination” or “favorite” by the user.

  The information stored as the action history is not limited to this, and any information may be used as long as the information can be used to specify the user's preference and the action range. The action history may be deleted from the action history storage unit 24 according to the passage of a predetermined period or the user's operation.

  The calendar information storage unit 25 is a storage medium that stores the calendar information created by the calendar information creation unit 16.

  FIG. 5 is an explanatory diagram showing an example of the storage state of calendar information in the calendar information storage unit 25. As shown in FIG. 5, the calendar information in this example includes the date, the event ID indicating the registered event information, and the event information (in this example, the event ID) registered in the calendar information storage unit 25. Event registration date indicating the date and event registrant.

  Here, the “event registrant” is information indicating that event information is registered in the calendar information storage unit 25. In this example, it is assumed that “navigation” is set in the event information registered by the control unit 10 and “user name” is set in the event information directly input by the user in calendar-related processing described later.

  The schedule information management table 26 is a storage medium that stores schedule information indicating a schedule input by the user via the input unit 70. In addition, the schedule information in this example includes information that can specify a place where the vehicle is scheduled to move in addition to the contents described in a general schedule book such as a document showing the contents of the schedule and the date and time (for example, guidance target Including the name of the object). Since both the schedule information and the calendar information are displayed on the display screen of the output unit 40 simultaneously or separately as a calendar, the schedule information and the calendar information may be stored in the same storage unit. Hereinafter, a case where a calendar (event calendar) indicating event information searched based on the action history stored in the action history storage unit 24 is displayed separately from the calendar indicating the user's schedule will be described. In this case, it is preferable that the user can select any event information from the event calendar and register it in his / her schedule.

  Next, the operation of the navigation device 100 of this example will be described with reference to the drawings. Note that detailed descriptions of processes not particularly related to the present invention may be omitted.

  FIG. 6 is a flowchart illustrating an example of calendar-related processing executed by the navigation device 100. In the calendar related processing, processing related to the display of the event calendar (for example, processing after updating the calendar information or displaying the event calendar display screen including the event calendar, etc.) is performed.

  The calendar related process in this example is started when, for example, the control unit 10 receives a display request for an event calendar display screen by the user A of the navigation device 100. As a method for receiving a display request for an event calendar display screen, for example, a method for receiving a display request for a time selection screen from a general menu screen (for example, a screen that displays a list of functions that can be executed by the navigation device 100). Etc. are considered.

  In the calendar-related processing, first, the control unit 10 performs processing for displaying the event calendar display screen on the display screen of the output unit 40 by the calendar display unit 17. (Step S101).

  FIG. 7 is an explanatory diagram showing an example of an event calendar display screen. As shown in FIG. 7, the event calendar display screen includes an event calendar display area 101, a return button 102 for receiving a display request before displaying the event calendar, and a display switching for receiving a request for switching the event calendar display mode. A button 103 and an update button 104 for receiving a request for updating calendar information (that is, updating an event calendar).

  Here, as shown in FIG. 7, in the event calendar display area 101, a calendar corresponding to the date on which the calendar-related processing is executed (that is, a calendar indicating the current date) and event icons 101a and 101b can be selected. Is displayed. Here, the “event icon” is an icon indicating the time when the event indicated by the event information registered in the calendar information storage unit 25 is performed. In this example, the event icon is displayed at a position indicating the date on which the event is performed in the calendar displayed in the event icon display area 101.

  In this example, the type of event icon is determined according to the area where the event is performed. That is, in this example, the event icon 101a indicates that the “event area” in the event information is “national”, and the event icon 101b indicates that the “event area” is “a predetermined location registered in advance by the user (for example, The coordinates on the map indicating the home registered by the user (hereinafter referred to as “home”) are within a predetermined distance (periphery) ”.

  The input unit 70 displays various buttons in response to the display position of various buttons (for example, the search button 105) displayed on the display screen of the output unit 40 being pressed by, for example, the finger of the user A. The control unit 10 is notified of the execution request for the process assigned in advance.

  When the event calendar display screen is displayed, the control unit 10 accepts an event calendar update request (step S102). If the event calendar update request by pressing the update button 104 is not accepted (N in step S102), the control unit 10 proceeds to processing in step S106 and later described.

  On the other hand, upon receiving an event calendar update request (Y in 102), the control unit 10 causes the event information search unit 15 to determine a search condition for event information based on the user's behavior history and calendar information (step S10). S103). Here, it is determined as a search condition that it is within the range of the trajectory information indicated by the user's action history and includes a keyword extracted from the search history. The search condition determination method using the action history and the calendar information is not limited to this. For example, information (trajectory information, search history, and calendar information and event information items) used by the user for the search condition is used. It is good also as a structure which can be selected. In addition, the search condition may be that the event content is the same as the event content of the event information indicated by the event ID in the registered calendar information, or event information having a predetermined relevance.

  When the search condition is determined, the control unit 10 causes the event information search unit 15 to search for event information that satisfies the search condition (step S104).

  When the event information is searched, the control unit 10 causes the calendar information creation unit 16 to register the search result in the calendar information storage unit 25 and updates the calendar information (step S105). Specifically, the calendar information creation unit 16 includes an event ID indicating event information included in the search result, an event date (date), an event registration unit (calendar information update date), and an event registration. A person (in this case, “navi”) is associated and stored as calendar information. When there are a plurality of event dates and times (for example, for an event held for several days), the control unit 10 displays a screen for accepting date selection by the user on the display screen of the output unit 40. Alternatively, it may be configured to register all dates and times.

  When the calendar information is updated, the control unit 10 causes the calendar display unit 17 to shift to the process of step S101 and displays the event calendar display screen according to the updated calendar information.

  By using the user's action history and registered calendar information for updating the event calendar, it is possible to prevent the event information provided to the user by the event calendar from becoming excessive. In addition, event information according to the user's preference can be provided.

  On the other hand, in the process of step S102 in the calendar related process, when the event calendar update request by pressing the update button 104 is not accepted (N in step S102), the control unit 10 accepts the display request for the event content display screen. (Step S106). In this example, the control unit 10 issues a display request for an event content display screen that displays the event content corresponding to the pressed event icon in response to the display position of the event icons 101a and 101b being pressed. It is determined that it has been accepted.

  If the display request for the event content display screen is not accepted (N in step S106), the control unit 10 proceeds to the process in step S101. On the other hand, when the display request for the event content display screen is received (Y in step S106), the control unit 10 displays the event content display screen (step S107).

  FIG. 8 is an explanatory diagram illustrating an example of an event content display screen. As shown in FIG. 8, the event content display screen includes an event content display area 201 for displaying the event content, a return button 202 for receiving a display request for the event calendar display screen, and a route search button for receiving a search request for a recommended travel route. 203.

  Here, in the event content display area 201, event contents 201a to 201d corresponding to the calendar and the event icon displayed on the event calendar display screen are displayed. In this example, it is assumed that the event content is displayed for each date in the event content display area 201. Each event content displayed in the event content display area 201 is selected when the display position on the display screen is pressed once by the finger of the user A, for example, and is not selected when pressed in the same manner in the selected state. It becomes a state. In this example, when any one of the event contents 201a to 201d is selected, the control unit 10 sets other event contents to a non-selected state.

  When the event content display screen is displayed, the control unit 10 receives a search request for a recommended movement route (step S108). In this example, the control unit 10 relates to the event content that has been selected from the home when the route search button 203 is pressed when at least one of the event content 201a to 201d is in the selected state. It is determined that a request for searching for a recommended movement route to the guidance target indicated by the POI information (that is, the POI information indicated by the related POI corresponding to the event content) is received. For example, when the event date is the current date, the control unit 10 searches for a recommended travel route from the current position of the vehicle to the guidance object indicated by the POI information related to the event content in the selected state. It may be configured to determine that the request has been received.

  Here, when the search request for the recommended movement route is not accepted (N in Step S108), the control unit 10 proceeds to the process of Step S101.

  On the other hand, when a search request for a recommended movement route is received (Y in step S108), the control unit 10 derives a recommended movement route for moving from the home to the POI related to the event content by the route search unit 11 (step S108). S109). At this time, the control unit 10 refers to the event information storage unit 23, and when there are a plurality of POIs related to the event information, the control unit 10 displays a screen for accepting selection of the POI as a destination by the user on the output unit 40.

<Second Embodiment>
Although the navigation apparatus has been described in the above-described embodiment, the embodiment of the present invention is not limited to this. That is, the present invention can also be implemented in the form of a center system (or navigation system) comprising a center server and a plurality of navigation devices. That is, it differs from the first embodiment described above in that various information regarding the calendars of a plurality of navigation devices are collectively managed by the center server. In the description relating to the second embodiment described below, the description will focus on parts different from the example of the first embodiment described above. Therefore, the same components as those in the first embodiment are denoted by the same reference numerals, and the description thereof is omitted. Unless otherwise specified, the same components are assumed to be the same.

  FIG. 10 is a block diagram showing an example of the configuration of the center system 200 according to the second embodiment of the present invention.

  As shown in FIG. 10, the center system 200 includes a center server 110 and a plurality of navigation devices 101 to 10N (N is an arbitrary positive integer) having the same function as the navigation device 100. The center server 110 and each of the plurality of navigation devices 101 to 10N transmit and receive various types of information via a communication network 120 such as the Internet. Note that the center system 200 has the functions of the navigation device 100 in the example of the first embodiment described above (that is, creation, search, storage, etc. of various information) in each of the center server 110 and the navigation devices 101 to 10N. What is necessary is just to be set as the structure which implement | achieves.

  The center server 110 is configured by an information processing apparatus such as a WWW server. The center server 110 in this example is managed by an administrator of the center system 200, and includes an event information DB (database; the same applies hereinafter) 111, an action history DB 112, a calendar information DB 113, and a schedule information DB 114.

  The action history DB 112, the calendar information DB 113, and the schedule information DB 114 are storage media that store an action history (see FIG. 4), calendar information (see FIG. 5), and schedule information for each user of the navigation devices 101 to 10N, respectively. .

  The event information DB 111 is a storage medium that stores event information (see FIG. 3). The event information stored in the event information DB 111 corresponds to the ranking of event information provided to the plurality of navigation devices 101 to 10N (ie, ranking based on the number of times registered in the calendar information DB 113, for example). It may be configured to be attached.

  Next, the operation of the center system 200 will be described with reference to the drawings.

  FIG. 11 is a flowchart illustrating an example of event calendar processing executed by the center system 200 when an event calendar (see FIG. 7) is displayed on the navigation device 101.

  The event calendar display process is started in response to the start of communication between the navigation device 101 and the center server 110, for example.

  In the event calendar process, the navigation apparatus 101 determines whether a new action history has been acquired (step S201). If it is determined that a new action history has not been acquired (N in step S201), the navigation apparatus 101 proceeds to a process in step S203 described later.

  On the other hand, if it is determined that a new action history (for example, trajectory information or search history) has been acquired (Y in step S201), the navigation apparatus 101 transmits the acquired action history to the center server 110 (step S202).

  The center server 110 receives the action history transmitted from the navigation device 101 (step S301). When the behavior history is received, the center server 110 identifies the user corresponding to the received behavior history (that is, the user of the navigation device 101), and registers the received behavior history in the behavior history DB 112 (step S302). Note that, as a user identification method, for example, a general user management method using a user ID is used, and thus detailed description thereof is omitted here.

  On the other hand, when the action history is transmitted, the navigation apparatus 101 determines whether or not an input of schedule information by the user has been received (step S203). Here, for example, if it is determined that the schedule information input is not received by not receiving the schedule information input within a predetermined time (N in step S203), the navigation apparatus 101 proceeds to the process in step S205 described later. To do.

  On the other hand, if it is determined that the input of schedule information has been received (Y in step S203), the navigation apparatus 101 transmits the received schedule information to the center server 110 (step S204).

  The center server 110 receives the schedule information transmitted from the navigation device 101 (step S303). Upon receiving the schedule information, the center server 110 identifies a user corresponding to the received schedule information, and registers the received schedule information in the schedule information DB 114 (step S304).

  On the other hand, when the schedule information is transmitted, the navigation apparatus 101 determines whether or not an event calendar display request has been received (step S205). If it is determined that the event calendar display request is not accepted (N in step S205), the navigation apparatus 101 proceeds to the process in step S201.

  On the other hand, if it is determined that an event calendar display request has been received, the navigation apparatus 101 transmits an event calendar display request to the center server 110 (step S206).

  The center server 110 receives the event calendar display request transmitted from the navigation device 101 (step S305). When receiving the event calendar display request, the center server 110 searches the event information based on the behavior history and schedule information of the user of the navigation device 101 and updates the calendar information (step S306). In this example, the center server 110 has a POI within the action range indicated by the action history and related to the schedule information (for example, a POI belonging to the same area as the point indicated by the schedule information or a user preference that can be specified from the schedule information) Calendar information is updated by searching event information (see FIG. 3) including the related POI in the related POI and registering the event ID indicating the event information included in the search result in the calendar information DB 113. (See FIG. 5).

  When the calendar information is updated, the center server 110 creates an event calendar display screen based on the updated calendar information (step S307). Here, the center server 110 may create an event calendar display screen indicating the user's schedule indicated by the schedule information.

  When the event calendar display screen is created, the center server 110 transmits the created event calendar display screen to the navigation device 101 (step S308).

  The navigation apparatus 101 receives the event calendar display screen transmitted by the center server 110 (step S207). When receiving the event calendar display screen, the navigation apparatus 101 displays the event calendar display screen (step S208) (see FIG. 7).

  When the event calendar display screen is displayed, the navigation apparatus 101 receives a display request for the event content display screen (step S209).

  Here, when the display request for the event content display screen is received (Y in step S209), the navigation device 101 displays the event content display screen (step S210) (see FIG. 8).

  When the event content display screen is displayed, the navigation apparatus 101 uses the recommended travel route using the route search button 203 (for example, POI information corresponding to the event content selected by the user on the event content display screen from the home (that is, A search request for a recommended travel route to the guidance object indicated by the POI information indicated by the related POI is received (step S211).

  If a search request for a recommended movement route is received (Y in step S211), the navigation apparatus 101 searches for a recommended movement route (step S212).

  When searching for the recommended travel route, the navigation apparatus 101 transmits schedule information including the recommended travel route and the selected event information to the center server 110 (step S213), and proceeds to the processing of step S201.

  In the above description regarding the processing from step S209 to step S213, the description of the same part as the processing from step S106 to S119 of the calendar-related processing in the example of the first embodiment is partially omitted (FIG. 6).

  On the other hand, the center server 110 receives the schedule information transmitted from the navigation device 101 (step S309). Upon receiving the schedule information, the center server 110 identifies the user, registers the received schedule information in the schedule information DB 114 (step S310), and proceeds to the process of step S301.

  The event calendar display process by the center system 200 is terminated when the communication between the navigation device 101 and the center server 110 is terminated, for example.

  As described above, in the second embodiment, the current position of the moving body (for example, a vehicle) is displayed on the map on the display screen of the display device (for example, the output unit 40) to display the moving body as the destination. In the center system 200 that includes a plurality of navigation devices 101 to 10N that guide to the center and a center server 110 that communicates with the navigation devices 101 to 10N via the communication network 120, the center server 110 includes a time when various events are performed. An event information DB 111 that stores event information in which event names and POI information indicating guidance objects related to the event are associated with each other, and an action history DB 112 that stores the action history of the users of the navigation devices 101 to 10N are provided. Based on the action history stored in the action history DB 112, Event information is searched from the information DB 111, calendar information is created based on the time when the event indicated by the searched event information is performed (or the calendar information is updated), and the created calendar information is stored in the navigation devices 101 to 10N ( For example, the navigation devices 101 to 10N store the behavior history of the users of the navigation devices 101 to 10N, transmit the stored behavior history to the center server 110, and are transmitted from the center server 110. Since the calendar (for example, event calendar, see FIG. 7) is displayed on the display screen of the display device (for example, the output unit included in the navigation device 101) according to the calendar information, a highly useful calendar is provided to the user. become able to.

  Further, since the center server 120 collectively manages information handled by the plurality of navigation devices 101 to 10N, for example, popular event information can be preferentially provided and the usefulness of the calendar can be enhanced. It becomes like this.
