Is transmitted in association with the position of the terminal device.

  Said server apparatus is comprised so that communication with the some terminal device utilized in a some mobile body is realized, and communication between several terminal devices is implement | achieved. The receiving unit receives a message input by the user to the terminal device, and the storage unit stores the received message in association with the position of the terminal device that has received the message. Then, when there is a position stored in association with the message on the guidance route set in the terminal device, the transmission means transmits the message to the terminal device. The guidance route may be set by the server device or by the terminal device. Further, as described above, when the transmission unit transmits a message to the terminal device, the storage unit further stores the message in association with the position of the terminal device. The message data stored in this way is also subject to transmission thereafter. That is, the transmission unit transmits not only the message received by the reception unit (message input by the user of the terminal device) but also the message stored when the message is transmitted (automatically copied message) to the terminal device. To do.

  As described above, after the message input by the user is first stored, the message is automatically copied every time the message is transmitted to the terminal device, so that the same message is associated with a plurality of positions on the map. Data will be generated. Therefore, once a message is registered, a chain of messages automatically occurs and spreads all at once. Therefore, according to said server apparatus, it becomes possible to implement | achieve the communication which can share a message substantially in real time between the users of a some terminal device. Specifically, according to the server device described above, unlike the information such as “distribution without actually going” like the distribution information on the Internet, the user can actually “obtain it by going to the place”.

  In another aspect of the above server device, the receiving means sets the number of distances from the current position of the terminal device on the guidance route that the user has set for the terminal device to receive the message. And the transmission means stores the position stored in association with the message within the range defined by the number of distances on the guidance route set in the terminal device. If the message exists, the message is transmitted to the terminal device.

  According to this aspect, on the guidance route, it is possible to appropriately transmit only messages that exist ahead of the number of distances set by the user from the current position of the terminal device to the terminal device. Note that the “number of distances” is used to set the extent to which a message existing from the current position of the terminal device is acquired on the guidance route.

  In another aspect of the server device, the storage unit stores the message, the position, and a section on the map where the position exists in association with each other, and the transmission unit includes the message, The section on the map is transmitted.

  In this aspect, the server device transmits, together with the message, a section on the map created based on, for example, an intersection or a road name to the terminal device. As a result, the user can easily grasp the position where the message exists (that is, the position on the map that is closely related to the message).

In another aspect of the server device, the storage unit stores the message, the position, and an image taken at a point where the message is input in association with each other, and the transmission unit The image can be sent with the message,
In another aspect of the server device, the server device further includes route search means for searching for the guidance route to be set for the terminal device, wherein the route search means sends the message to the terminal device. In the case of transmission, when an action to avoid the road on the guidance route set in the terminal device is performed, a new guidance route that does not include the road on which the behavior to avoid is performed is searched.

  According to this aspect, it is possible to appropriately avoid traffic jams and accidents, and to reduce traffic jams themselves.

  In another aspect of the server device, when the predetermined time has elapsed since the reception unit received the message, or the predetermined time has elapsed since the storage unit stored the message for the first time. At this time, it further comprises an erasure unit for erasing the message.

  According to this aspect, in the terminal device, unnecessary message guidance can be appropriately stopped, and only necessary messages can be guided.

  Preferably, the erasing unit sets the predetermined time according to the content of the message. For example, the erasure unit can set a predetermined time for erasing the message according to the category associated with the message. In one example, when the category is a traffic jam or an accident, the predetermined time is set to a relatively short time, and when the category is sightseeing, the predetermined time is set to a relatively long time.

  In another aspect of the present invention, an information processing method performed by a server device configured to be communicable with a plurality of terminal devices used in a plurality of mobile objects includes a message input by the user to the terminal device. A receiving step received from the device, a storage step of storing the message received in the receiving step in association with a position of the terminal device that has received the message, and a guidance route set in the terminal device A transmission step of transmitting the message to the terminal device when the location stored in association with the message exists in the storage step, wherein the storage step is the transmission step When transmitting the message to the terminal device, the message is further stored in association with the position of the terminal device.

[Information processing method]
Next, an information processing method performed by the server device 1 and the terminal device 2 in the present embodiment will be described.

  In this embodiment, the server device 1 receives a message input by the user to the terminal device 2 and registers the received message in association with the position of the terminal device 2. In this case, the server device 1 generates and stores message data in which the message is associated with the position of the terminal device 2. And the server apparatus 1 transmits the message which the said message data has with respect to the said terminal device 2, when the position which the stored message data has on the guidance route set to the terminal apparatus 2 exists. To do. In other words, the server device 1 selects the terminal device 2 in which the position of the message data exists on the guidance route from among the plurality of terminal devices 2, and the message that the message data has for the selected terminal device 2 Send. Thereafter, the terminal device 2 that has received the message from the server device 1 guides the received message to the user.

  Furthermore, when the server apparatus 1 transmits a message as described above, the server apparatus 1 further registers the message in association with the position of the terminal apparatus 2 that transmitted the message. That is, the server device 1 automatically generates and stores new message data in which the message is associated with the position of the terminal device 2 without depending on the response in the terminal device 2 that has transmitted the message. The message data stored in this way is also a target to be transmitted thereafter. In addition, the message data is different from the message data corresponding to the message (hereinafter referred to as “original message” as appropriate) input by the user of the terminal device 2 as described above. Specifically, the message is the same, but the data associated with the message is different. In this way, after registering the original message, each time a message is transmitted to the terminal device 2, the message is automatically copied to generate data associated with a plurality of positions on the map for the same message. The Rukoto.

  Therefore, once the original message is registered, the message chain is automatically generated and spreads at once (specifically, the message chain is generated in the terminal device 2 where the position of the message data exists on the guidance route). ). Therefore, according to the present embodiment, it is possible to realize communication based on word-of-mouth information, in which messages can be shared between users of a plurality of terminal devices 2 in substantially real time. That is, according to the present embodiment, unlike the information such as “distributed information without actually going” as in the case of Internet distribution information, for example, the user can actually obtain local information such as “obtained by going to the place”. Such information can be distributed, a local community can be formed, and the use of such a community can be promoted.

  Hereinafter, the flow of information processing performed by the server device 1 and the terminal device 2 will be described more specifically.

  First, the terminal device 2 is information relating to settings for registering a message in the server device 1 and / or settings for receiving (acquiring) a message from the server device 1 (hereinafter referred to as “message registration / reception setting information”). .) Is acquired from the user, and the acquired message registration / reception setting information is transmitted to the server apparatus 1. Specifically, the terminal device 2 uses, as message registration / reception setting information, at least the category to which the message to be transmitted and / or the message to be received belongs, and the current state of the terminal device 2 on the guidance route when the message is received. Get the number of distances from the position. This category corresponds to the type of message registered / received by the user, and includes, for example, traffic information including information on traffic jams, construction, accidents, etc., and tourist information including information on sightseeing spots. The distance number is used to set how far a message that exists on the guidance route is to be acquired. For example, “1 (km)”, “3 (km)”, “5 (km)”, “10 (km)” or the like can be set. In addition, when performing message registration / reception settings as described above, the user can set or edit a character string template used for registering a message. For example, there are templates such as “I got stuck in a traffic jam!” And “I got XX in such a place!”.

  Then, when a message is input by the user, the terminal device 2 transmits the message to the server device 1. For example, the user inputs a message to the terminal device 2 by operating the operation unit 28 or inputting voice via the microphone 27. In one example, the user calls a message from the above template and creates a character string such as “I got stuck in a traffic jam!” Or “I found a convenience store in this place!”. Further, the terminal device 2 can transmit the message input in this way to the server device 1 together with an image captured by the camera 29 at the point where the message is input. For example, when a message is input, the terminal device 2 requests the user to determine whether or not to capture an image, and causes the camera 29 to capture an image when the user determines to capture an image. In the following, it is assumed that the “message” transmitted from the terminal device 2 to the server device 1 includes not only character strings and voice data but also image data from the camera 29.

  On the other hand, the server device 1 receives the message registration / reception setting information as described above from the terminal device 2, and generates / stores a message or transmits a message based on the received message registration / reception setting information. First, when the server device 1 receives a message input to the terminal device 2 by the user, the server device 1 automatically gives a tag to the message. Specifically, when the server device 1 receives a message from the terminal device 2, the server device 1 includes at least the message, the position of the terminal device 2, and the message registration / reception setting information received from the terminal device 2. Message data in which the included categories are associated is generated and stored. As the position of the terminal device 2, the position coordinates obtained by the GPS unit 24 in the terminal device 2 can be used. In this case, when the server device 1 receives a message from the terminal device 2, the server device 1 also receives the position coordinates obtained by the GPS unit 24 in the terminal device 2. Furthermore, in addition to such a message, position, and category, the server device 1 receives the time when the message is received from the terminal device 2, the section on the map where the terminal device 2 that transmitted the message exists, the terminal It is possible to generate message data in which an image captured by the camera 29 of the device 2 (only when the image exists) is associated. The “section on the map” is set by the server device 1 based on the stored map data. For example, the sections on the map are set based on intersections, road names, and the like. The “time” stored as the message data is not limited to the time when the server apparatus 1 receives the message, but uses the time when the server apparatus 1 registers the message or the time when the user inputs the message to the terminal apparatus 2. Is also good (the same shall apply hereinafter).

  Thereafter, the server apparatus 1 determines the terminal apparatus 2 based on the guidance route set in the terminal apparatus 2 and the category and distance number included in the message registration / reception setting information received from the terminal apparatus 2. Send a message. In this case, the server device 1 stores the guidance route set for the terminal device 2 and determines the position coordinates of the terminal device 2 (that is, the current position of the terminal device 2) from the GPS unit 24 of the terminal device 2 for a predetermined time. The terminal device 2 to which the message is to be transmitted is determined based on such a guidance route and position coordinates. Specifically, the server device 1 matches the category set in the message data with the category set in the terminal device 2, and the distance set in the terminal device 2 and the current position of the terminal device 2 The message is transmitted to the terminal device 2 when the position of the message data exists within the range on the guidance route defined by the above. By doing so, it is possible to appropriately transmit to the terminal device 2 a message that exists ahead of the guidance route (exists the number of distances described above) and belongs to the category that the user wants to acquire. Become.

  Specifically, when the server device 1 transmits a message to the terminal device 2 as described above, the server device 1 also transmits a position associated with the message and a section on the map. Further, when the message data includes an image from the camera 29, the server device 1 also transmits the image to the terminal device 2. In the following, it is assumed that the “message” transmitted from the server apparatus 1 to the terminal apparatus 2 includes not only character strings and voice data but also image data from the camera 29.

  When the message is transmitted to the terminal device 2 in this way, the terminal device 2 guides the message to the user. Specifically, the terminal device 2 displays an image corresponding to the message on the display unit 25 or outputs sound corresponding to the message from the speaker 26. When the terminal device 2 displays a message, the character string corresponding to the message is displayed at the position corresponding to the message (corresponding to the data of the position received from the server device 1) on the map for route guidance. Display images of. In this case, the terminal device 2 displays an image of the character string corresponding to the section on the map together with the character string corresponding to the message. In addition, when the message received from the server device 1 includes an image from the camera 29, the terminal device 2 also displays the image on the display unit 25.

  On the other hand, when the server device 1 transmits a message to the terminal device 2 as described above, the server device 1 newly generates message data in which the message is associated with the position of the terminal device 2 that has transmitted the message. Remember. In this case, the server device 1 automatically generates and stores such message data without depending on the response at the terminal device 2 that transmitted the message. Specifically, the server device 1 associates the message, the position of the terminal device 2, the category, the time, the section on the map, and the image by the camera 29 (only when the image exists). Generate message data. In the message data, the original message data (that is, message data corresponding to the original message) can be used as it is for the message, the category, the section on the map, and the image by the camera 29.

  Thereafter, the server device 1 transmits the message to the terminal device 2 as described above using the message data newly stored as described above, and stores the new message data when the message is transmitted. I do. By doing this, a chain of messages can be generated automatically and spread at once. Therefore, it is possible to form a local community and promote the use of such a community.

  Hereinafter, a specific example regarding information processing performed by the server device 1 and the terminal device 2 will be described with reference to FIGS. 3 to 6.

  FIG. 3 shows a specific example of the message data 40 generated and stored by the server device 1. As shown in FIG. 3, the message data 40 includes message category data 41, time data 42 when the server apparatus 1 receives a message from the terminal apparatus 2, and position data 43 of the terminal apparatus 2 that transmitted the message. And the data 44 of the section on the map where the terminal device 2 that transmitted the message exists, the character string data 45 corresponding to the message, and the image (captured image) captured by the camera 29 of the terminal device 2 that transmitted the message. ) Data 46. The category data 41 is, for example, data indicating traffic jams, construction works, accidents, sightseeing, and the like. The position data 43 is, for example, position coordinate data obtained by the GPS unit 24 in the terminal device 2. As the data 44 of the section on the map, for example, data “beyond X street Y intersection” and “between X street Y intersection and Z intersection” can be cited. Examples of the character string data 45 include data such as “I got stuck in a traffic jam!” And “I have a convenience store in such a place!”.

  FIG. 4 shows an example of a map image displayed on the display unit 25 of the terminal device 2. As indicated by reference numeral 51 in FIG. 4, the positions of a plurality of terminal devices 2 that communicate with the server device 1 (for example, terminal devices 2 that have subscribed to a predetermined service) are displayed on the map by icons. For example, the category of information registered at the position is represented by the type of icon. As an example, by displaying the icon in red, emergency information such as traffic jams and accidents is expressed.

  FIG. 5 shows another example of the map image displayed on the display unit 25 of the terminal device 2. Similar to FIG. 4, as indicated by reference numeral 61, the positions of a plurality of terminal devices 2 that communicate with the server device 1 (for example, the terminal devices 2 that have subscribed to a predetermined service) are displayed on the map. Further, as indicated by reference numeral 62, the guide route set in the terminal device 2 is displayed.

  FIG. 6 shows an image example in which a message is displayed on the map image as shown in FIG. First, as indicated by reference numeral 71, it is assumed that the user of the terminal device 2 existing at one location on the map inputs a message (original message) such as “There is a shop that is popular”. In this case, the server device 1 generates and stores message data that associates such an original message with the position of the terminal device 2 that transmitted the original message to the server device 1. FIG. 6 shows a diagram after a certain amount of time has elapsed since the original message was input.

  Next, as indicated by reference numeral 72, the server device 1 transmits a message such as “There are some popular stores” to the terminal devices 2 existing at a plurality of locations on the map. To do. Specifically, the server device 1 sets a category that matches the category of message data (not limited to message data directly generated from an original message, but also includes message data obtained by automatically copying the message data). The message is transmitted to the terminal device 2 for which the number of distances on the guidance route including the position of the message data is set. In this case, the server device 1 adds a section on the map such as “between X and Y intersections and Z intersections” included in the message data to the message and transmits the message to the terminal device 2. The section on the map is set by the server device 1 by referring to the map data based on the position of the terminal device 2 to which the original message is input. Further, when the server device 1 transmits a message as described above, the server device 1 generates and stores message data in which the message and the position of the terminal device 2 that transmitted the message are associated with each other. In FIG. 6, such processing is expressed as “hear and copy”.

  Thereafter, as indicated by reference numeral 73, the user of the terminal device 2 existing at one location on the map responds to a message “There is a popular store” as “XX shop! ”(Hereinafter referred to as“ additional message ”as appropriate). In this case, the server device 1 generates and stores message data in which a message in which an additional message is added to the original message described above and the position of the terminal device 2 that transmitted the additional message to the server device 1 are associated with each other. To do. When a plurality of additional messages are input to the original message, the server device 1 stores the history of the input messages.

  Next, as indicated by reference numeral 74, the server device 1 sends an “X street and Y intersection” including an original message, a section on the map, and an additional message to the terminal devices 2 existing at a plurality of locations on the map. A message such as “There are some popular shops” or “XX shop!” Is transmitted between the Z intersections. Specifically, the server device 1 matches a category included in message data (not limited to message data directly generated from an original message and an additional message, but also includes message data obtained by automatically copying these message data). A message is transmitted to the terminal device 2 in which the category to be set is set and the number of distances on the guide route including the position of the message data is set. Further, when the server device 1 transmits a message as described above, the server device 1 generates and stores message data in which the message and the position of the terminal device 2 that transmitted the message are associated with each other. In FIG. 6, such processing is expressed as “hear and copy”.

  As can be seen from FIG. 6, once a message is registered, a chain of messages (chain reaction) automatically occurs and spreads all at once. Thereby, the communication which can share a message substantially in real time between the users of a plurality of terminal devices 2 is realizable. Therefore, a local community can be formed and the use of such a community can be promoted. Therefore, for example, it is possible to appropriately avoid traffic jams and accidents, and to reduce traffic jams themselves.

  The server device 1 can perform the following processing in addition to the processing described above.

  When the server device 1 transmits a message to the terminal device 2, specifically, when a message indicating a traffic jam, an accident or a construction is transmitted, the server device 1 avoids a road on the guide route set in the terminal device 2. When an action to be performed is performed, a new guide route that does not include a road on which an action to be avoided is included can be searched. In other words, the server device 1 can search for a guidance route that does not include roads such as avoided traffic jams, accidents, and construction, in other words, can perform a reroute. In this case, the server device 1 is based on the category of the message transmitted to the terminal device 2, the position associated with the message, the guidance route set in the terminal device 2, the current position of the terminal device 2, and the like. Then, it is determined whether or not an avoidance action has been performed by the terminal device 2, and when the avoidance action is performed, the road on which the avoidance action has been performed is specified. Then, the server device 1 searches for a new guidance route that does not include the identified road. As a result, it is possible to appropriately avoid traffic jams and accidents, and to reduce traffic jams themselves.

  When a new guidance route is set as described above, the message that has been guided up to that point is deleted. Specifically, image display and audio output corresponding to the message are stopped. Further, when the avoidance action is performed in the terminal device 2, the server device 1 can automatically copy the message transmitted to the terminal device 2.

  Furthermore, the server device 1 can delete the above-described message when a predetermined time has elapsed. Specifically, the server device 1 receives the message transmitted from the terminal device 2 when the predetermined time has elapsed, or when the predetermined time has elapsed since the message was stored. It is possible to transmit an instruction to stop the guidance of the message at. That is, it is possible to transmit an instruction to stop image display or audio output corresponding to the message on the terminal device 2. In one example, the server device 1 can set a predetermined time for deleting the message according to the content of the message, specifically according to the category associated with the message. In this example, the server device 1 sets the predetermined time to a relatively short time when the category is a traffic jam or an accident, and sets the predetermined time to a relatively long time when the category is sightseeing or the like. Set. In another example, a user who inputs an original message can set a predetermined time for deleting the message. By deleting the message in this manner, unnecessary message guidance can be appropriately stopped and only necessary messages can be guided.

  In addition, you may comprise so that deletion of the above messages can be performed by the terminal device 2 side. For example, message guidance may be stopped in response to a user operation on the operation unit 28 or voice input to the microphone 27.

[Processing flow]
Next, specific processing performed by the server device 1 and the terminal device 2 in the present embodiment will be described.

  FIG. 7 is a flowchart illustrating processing performed by the server device 1 and the terminal device 2 in the present embodiment. In this process, basically, the control unit 11 in the server device 1 and the control unit 21 in the terminal device 2 execute programs stored in advance in the server device 1 and the terminal device 2, respectively. It is realized with.

  First, the terminal device 2 acquires the current position obtained by the GPS unit 24 and also acquires the destination input by the user (step S11). Then, the terminal device 2 makes a route guidance request to the server device 1 by designating the current position and the destination (step S12).

  The server device 1 executes a route search by referring to the map data stored in the map database 13 based on the current position and the destination received from the terminal device 2 (step S13), and obtained by the search. The guidance route is transmitted to the terminal device 2 (step S14). The terminal device 2 receives the guidance route from the server device 1 and displays it on the display unit 25 (step S15).

  Next, the terminal device 2 acquires message registration / reception setting information input by the user (step S16), and transmits the acquired message registration / reception setting information to the server device 1 (step S17).

  Here, the message registration / reception setting information acquisition process will be specifically described with reference to FIG. FIG. 8 is a flowchart showing message registration / reception setting information acquisition processing executed by the terminal device 2.

  First, the terminal device 2 acquires the number of distances from the current position of the terminal device 2 on the guidance route when receiving a message from the user (step S31). This distance number is used to set how far a message that exists from the current position of the terminal device 2 is acquired on the guidance route. For example, the user operates the operation unit 28 or inputs voice through the microphone 27, so that the distance number is “1 (km)”, “3 (km)”, or “5 (km)”. Or “10 (km)” is set.

  And the terminal device 2 acquires the category to which the message to transmit and / or the message to receive belongs from a user (step S32). This category corresponds to the type of message registered / acquired by the user. For example, categories include traffic jams, construction work, accidents, and tourism. Further, for example, the user sets the category by operating the operation unit 28 or inputting sound through the microphone 27.

  Then, the terminal device 2 receives information on setting and editing of a character string template used when registering a message from the user (step S33). For example, there are templates such as “I got stuck in a traffic jam!” And “I got XX in such a place!”. Then, after step S33, the process ends. Note that the information regarding template setting and editing may not be included in the message registration / reception setting information transmitted from the terminal device 2 to the server device 1.

  Next, returning to FIG. 7, the processing after step S18 will be described. The terminal device 2 determines whether a message is input from the user (step S18). For example, the terminal device 2 acquires a message input by the user via the operation unit 28 or the microphone 27. In one example, the user calls a message from the template described above, and creates and inputs a character string such as “I got stuck in a traffic jam!” Or “I have a convenience store in this place!”.

  When a message is input (step S18; Yes), the terminal device 2 transmits the message to the server device 1 (step S19). In this case, the terminal device 2 transmits the current position obtained by the GPS unit 24 together with the message. In addition, when an image is captured by the camera 29 (for example, when the user captures an image using the camera 29 when inputting a message), the terminal device 2 also transmits the captured image together.

  Next, the server device 1 generates and stores message data based on the message received from the terminal device 2 (step S20). That is, the server device 1 automatically assigns a tag for the received message. Specifically, the server apparatus 1 receives the message received from the terminal apparatus 2, the position received from the terminal apparatus 2 (the current position obtained by the GPS unit 24), and the image received from the terminal apparatus 2 ( Only when the image exists), the category included in the message registration / reception setting information received from the terminal device 2, the time when the message was received from the terminal device 2, and the terminal device 2 that transmitted the message The message data in which the section on the map to be associated is associated is generated, and the message data is stored in the message database 14. In this case, the server device 1 sets a section on the map by referring to the map data based on the position of the terminal device 2 that has transmitted the message. For example, the server device 1 sets sections on the map based on intersections, road names, and the like.

  Next, the server apparatus 1 determines whether there is a message to be transmitted to the terminal apparatus 2 (step S21). Specifically, the server device 1 receives the guidance route set in the terminal device 2, the current position of the terminal device 2 (current position obtained by the GPS unit 24), and the message registration / reception received from the terminal device 2. The determination is performed based on the category and the number of distances included in the reception setting information. In this case, the server device 1 has a category set in the terminal device 2 that matches the category of the message data, and is defined by the number of distances set in the terminal device 2 and the current position of the terminal device 2. When the position of the message data exists within the range on the guidance route to be determined, it is determined that the message of the message data should be transmitted to the terminal device 2.

  When there is a message to be transmitted to the terminal device 2 (step S21; Yes), the server device 1 transmits the message to the terminal device 2 (step S22). In this case, the server device 1 also transmits a position associated with the message and a section on the map to the terminal device 2 together with the message. Further, when the message data includes an image from the camera 29, the server device 1 also transmits the image to the terminal device 2. If there is no message to be transmitted to the terminal device 2 (step S21; No), the process proceeds to step S25.

  Next, when the terminal device 2 receives a message from the server device 1, the terminal device 2 guides the message to the user (step S23). Specifically, the terminal device 2 displays an image corresponding to the message on the display unit 25 or outputs sound corresponding to the message from the speaker 26. When the terminal device 2 displays a message, the character string corresponding to the message is displayed at the position corresponding to the message (corresponding to the data of the position received from the server device 1) on the map for route guidance. Display images of. In this case, the terminal device 2 displays an image of the character string corresponding to the section on the map together with the character string corresponding to the message. In addition, when the message received from the server device 1 includes an image from the camera 29, the terminal device 2 also displays the image on the display unit 25.

  When the server device 1 transmits a message to the terminal device 2 as described above, the server device 1 newly generates message data in which the message is associated with the position of the terminal device 2 that transmitted the message. (Step S24). Specifically, the server device 1 corresponds to the message, the position of the terminal device 2, the category, the time, the section on the map, and the image by the camera 29 (only when the image exists). Generate attached message data. In the message data, the original message data (that is, message data corresponding to the original message) can be used as it is for the message, the category, the section on the map, and the image by the camera 29.

  Next, the server device 1 determines whether the terminal device 2 has arrived at the destination of route guidance based on the position received from the terminal device 2 (the current position obtained by the GPS unit 24). (Step S25). When arriving at the destination (step S25; Yes), the server device 1 notifies the terminal device 2 of the end of route guidance (step S26). On the other hand, when the destination has not been reached (step S25; No), the process returns to step S20. Thus, the route guidance is continued until the terminal device 2 arrives at the destination, during which the server device 1 generates and stores message data and the server device 1 transmits a message to the terminal device 2. The process is repeated.

  Here, the reroute process executed by the server apparatus 1 will be described with reference to FIG. FIG. 9 is a flowchart showing the reroute processing.

  First, the server device 1 determines whether or not an action for avoiding a road on the guidance route set in the terminal device 2 has been performed (step S41). Specifically, the server device 1 determines whether or not an avoidance action has been performed in the terminal device 2 based on the guidance route set in the terminal device 2 and the current position of the terminal device 2. In this case, the guide route set in the terminal device 2 can be the one stored when the server device 1 sets the guide route, and the current position of the terminal device 2 is obtained by the GPS unit 24. It is obtained by receiving the current position from the terminal device 2.

  When the avoidance action is performed on the terminal device 2 (step S41; Yes), the server apparatus 1 searches for a new guidance route that does not include the road on which the avoidance action is performed (step S42). Specifically, the server device 1 transmits the category (congestion, accident, construction, etc.) of the message transmitted to the terminal device 2, the position associated with the message, the guidance route set in the terminal device 2, and Based on the current position of the terminal device 2 and the like, the road on which the avoidance action has been performed is specified. Then, the server device 1 searches for a new guidance route that does not include the identified road. Next, the server device 1 transmits the new guidance route obtained by the search in step S42 to the terminal device 2 (step S43), and the process ends. On the other hand, when the avoidance action is not performed in the terminal device 2 (step S41; No), the server device 1 ends the process without searching for a new guidance route.

[Modification]
In the above, the embodiment in which substantial processing such as route search and route guidance is performed on the server device 1 side is shown, but instead, substantial processing such as route search and route guidance is performed on the terminal device side. It is also good. In this case, the terminal device can be configured by a so-called navigation device. However, the navigation device needs to be configured to be able to communicate with the server device 1. The navigation device transmits the guide route searched by itself to the server device 1. In this case, the reroute processing as described above is performed on the terminal device side. Specifically, after receiving a message from the server device 1, the terminal device includes a road on which an action to avoid is performed when an action to avoid a road on the set guidance route is performed. You can search for no new guidance routes. Specifically, the terminal device performs the avoidance action based on the category of the message received from the server device 1, the position associated with the message, the set guidance route, the current position of the terminal device, and the like. In addition, it is determined whether or not the road on which the avoidance action has been performed is determined. Then, the terminal device searches for a new guidance route that does not include the identified road.

  Furthermore, although the example which applies this invention to a vehicle was shown above, application of this invention is not limited to this. The present invention can be applied to various mobile objects such as ships, helicopters, and airplanes in addition to vehicles. In addition, the present invention can also be applied to terminal devices used by pedestrians. That is, the “moving body” includes pedestrians.

  As described above, the embodiments are not limited to the above-described embodiments, and can be appropriately changed without departing from the gist or concept of the invention that can be read from the claims and the entire specification.
