  Next, a waiting information providing program executed in the information management server 2 and the mobile information terminal constituting the information providing system 1 having the above configuration will be described with reference to FIGS. 5 and 6 are flowcharts of the waiting information providing program according to the present embodiment. Here, the waiting information provision program is a program that is executed when a predetermined operation is performed in the mobile information terminal 5 of the user 4 who wants to wait, and provides information necessary for waiting to each user 4 that waits. is there. Note that the programs shown in the flowcharts of FIGS. 5 and 6 below are stored in the RAM, ROM, or the like included in the information management server 2 or the mobile information terminal 5 and executed by the CPU 21 or CPU 31. In the following description, a user carrying the mobile information terminal 5 on which the waiting information providing program is executed is referred to as a self user, and a user who waits other than the self user is referred to as another user.

  First, a waiting information providing program executed in the mobile information terminal 5 will be described. In step (hereinafter abbreviated as “S”) 1, the CPU 31 of the mobile information terminal 5 activates a predetermined application program in the mobile information terminal 5, and displays information related to the waiting request (hereinafter referred to as waiting request information) on the application program. Input based on the user's operation. Note that the waiting request information includes information for specifying the “password” and the “waiting place”, respectively. Here, the “password” is identification information for specifying the user who is to wait for on the information management server 2 side as will be described later. The “meeting place” may be specified by inputting a facility name, or may be performed by designating a point to be a meeting place on the map. In addition, “waiting time” may also be input as waiting request information.

  Next, in S <b> 2, the CPU 31 transmits the waiting request information input in S <b> 1 to the information management server 2 including information (such as a user ID) that identifies the user who is the sender. The above S1 and S2 are performed only in the mobile information terminal 5 of any one of the plurality of users 4 who are waiting, and only the processes after S3 are performed in the mobile information terminal 5 of the other user 4. Is done.

  Subsequently, in S3, the CPU 31 activates a predetermined application program in the mobile information terminal 5, and inputs a “secret word” on the application program. Note that the “secret word” to be input in S3 is the “secret word” input as waiting request information in S1. That is, the user who has correctly input the “password” input as the waiting request information in S1 is specified as the user who is waiting.

  Next, in S <b> 4, the CPU 31 transmits the “secret word” input in S <b> 3 to the information management center 3 including information (user ID and the like) specifying the user who is the sender.

  Thereafter, in S5, the CPU 31 receives information (facility ID, facility name, position coordinates, etc.) specifying the meeting place transmitted from the information management server 2. Note that the meeting place transmitted from the information management center 3 in S5 is basically the “waiting place” input as the waiting request information in S1, but information that the input meeting place is inappropriate. If the management server 2 determines, a new meeting place may be set in the information management server 2. Further, the information management server 2 may be configured to set an appropriate meeting place from the current position of the user performing the waiting without causing the user to input the meeting place. Note that the processing after S5 is performed only in the mobile information terminal 5 that has correctly input and transmitted the "password" input as the waiting request information in S1.

  In S6, the CPU 31 guides the currently set meeting place based on the information specifying the meeting place received in S5. For example, it is performed by displaying an icon or the like for specifying the meeting place on the map, or displaying the name of the facility that becomes the meeting place.

  Subsequently, in S <b> 7, the CPU 31 receives the position information request transmitted from the information management server 2. The position information request is a signal for requesting the current position of the user who is waiting.

  Next, in S8, the CPU 31 determines whether or not the mobile information terminal 5 is connected to the in-vehicle information terminal 7 and can communicate. The S8 is determined to be “YES” only immediately after the mobile information terminal 5 is switched from a state in which the mobile information terminal 5 is not connected to the in-vehicle information terminal 7 to a communicable state. While being connected to the information terminal 7, “NO” is determined. The communication between the mobile information terminal 5 and the in-vehicle information terminal 7 is performed by wireless communication using Bluetooth or the like. Therefore, the user carrying the mobile information terminal 5 gets on the vehicle 6 on which the in-vehicle information terminal 7 is mounted (that is, the mobile information terminal 5 and the in-vehicle information terminal 7 are within a communicable range), and the in-vehicle information terminal 7 Mobile information terminal 5 and in-vehicle information terminal 7 can communicate with each other. The communication between the mobile information terminal 5 and the in-vehicle information terminal 7 may be configured to be performed by wired communication. In that case, it is a condition that the mobile information terminal 5 and the in-vehicle information terminal 7 are connected by a cable.

  And when it determines with the mobile information terminal 5 being connected with the vehicle-mounted information terminal 7 and communicable (S8: YES), it transfers to S9. On the other hand, when it is determined that the mobile information terminal 5 is not communicable with the in-vehicle information terminal 7 or is continuously communicable (S8: NO), the process proceeds to S10.

  In S9, the CPU 31 transmits information (facility ID, facility name, position coordinates, etc.) specifying the meeting place received in S5 to the connected in-vehicle information terminal 7. As a result, the meeting place is set as the destination in the in-vehicle information terminal 7 as will be described later, and travel guidance based on the guide route to the searched destination is performed. However, as described later, when a destination is already set for the in-vehicle information terminal 7 and the destination is a destination set based on a user operation on the in-vehicle information terminal 7, the destination (That is, the meeting place transmitted from the mobile information terminal 5 is not set as the destination, and the currently set destination is maintained). The processing of the in-vehicle information terminal 7 will be described later.

  On the other hand, in S10, the CPU 31 acquires the current position of the mobile information terminal 5 based on the detection result of the GPS 40. In addition, you may use the detection result of other sensors (for example, gyro sensor etc.) with which the mobile information terminal 5 is provided other than GPS40 for acquisition of a present position.

Thereafter, in S11, the CPU 31 transmits the information on the current position of the mobile information terminal 5 acquired in S10 to the information management server 2. And the information management server 2 which acquired the information of the present position from the movement information terminal 5 updates the position management information 18 of the waiting management information DB 15 as will be described later. Specifically, the current position of the mobile information terminal 5 transmitted from each mobile information terminal 5 is specified as the current position of the user carrying the mobile information terminal 5. As a result, the information management server 2 can manage the current positions of all users who are waiting.
In this embodiment, the current position information of the mobile information terminal 5 is transmitted to the information management server 2 in response to the position information request transmitted from the information management server 2 in S7. A configuration may be adopted in which information on the current position of the mobile information terminal 5 is periodically transmitted to the information management server 2 regardless of whether there is an information request.

  Subsequently, in S <b> 12, the CPU 31 receives the current location information of all users included in the waiting group transmitted from the information management server 2. Note that the location information of the own user may not be received.

  In S <b> 13, the CPU 31 guides the position of the own user and other users other than the own user based on the position information of all users included in the waiting group received in S <b> 12. As a result, in addition to the meeting place, it is possible to grasp the own position and the position of the meeting partner. In S13, it is desirable to guide the recommended route from the user to the meeting place (destination). The recommended route may be searched by the information management server 2 and the search result may be received at S12 or may be searched by the mobile information terminal 5.

Here, FIG. 7 is a diagram showing an example of a guide screen 80 for meeting place information displayed on the display 38 in S13.
As shown in FIG. 7, the display 38 has a map image 81 around the user, a current location mark 82 indicating the current location of the user, a meeting location mark 83 that specifies a meeting place and a meeting time, and the user's own location. A recommended route 84 from the current position to the meeting place and a partner mark 85 that specifies the current position of another user who is the meeting partner are displayed. In addition, when there are a plurality of other users who are waiting parties, the partner mark 85 displays the positions of the plurality of other users. As a result, by referring to the guidance screen 80 displayed on the display 38, the user can grasp not only the meeting place but also the route to the meeting place and the current position of the meeting partner. The recommended route 84 and the waiting time may not be displayed.

  Thereafter, in S <b> 14, the CPU 31 determines whether an operation for changing the meeting place by the user has been received based on a signal transmitted from the input operation unit 39. Note that the change operation of the meeting place may be accepted only by the mobile information terminal 5 that has input the desired waiting information in S1, or the “secret word” input as the desired waiting information in S1 is correctly input in S3. In addition, all the mobile information terminals 5 that have transmitted (that is, mobile information terminals 5 carried by all users who are waiting) may be acceptable.

  And when it determines with having received the change operation of the meeting place by the user 4 (S14: YES), it transfers to S15. On the other hand, if it is determined that the user 4 has not accepted an operation for changing the meeting place (S14: NO), the process proceeds to S20.

  In S <b> 15, the CPU 31 uses information (hereinafter referred to as “waiting change information”) for identifying the waiting location after the change specified by the changing operation of the waiting location received from the user 4, as information for identifying the own user who is the sender (user ID, etc. ) To the information management server 2.

  Thereafter, in S <b> 16, the CPU 31 receives information (facility ID, facility name, position coordinates, etc.) specifying the changed meeting place transmitted from the information management server 2. In the process of S16, in addition to the in-vehicle information terminal 7 that transmitted the waiting change information in S15, the “password” input as the waiting request information in S1 is correctly input and transmitted in S3. It is performed in all the mobile information terminals 5 (that is, mobile information terminals 5 carried by all users who are waiting).

  Subsequently, in S17, the CPU 31 guides that the waiting place has been changed based on the information specifying the changed waiting place received in S16. For example, by outputting a sentence or voice indicating that the meeting has been changed, displaying an icon for specifying the changed meeting place on the map, or displaying the name of the facility that is the waiting place after the change Do.

  Further, when the recommended route to the meeting place is displayed on the display 38, the displayed recommended route is once deleted, and the recommended route to the waiting place after the change is newly displayed. For example, FIG. 8 shows an example of a guide screen 80 for meeting place information displayed on the display 38 when the meeting place is changed from “XX Station North Exit” to “XX Cafe”. As shown in FIG. 8, when the meeting place is changed, the position of the meeting place mark 83 indicating the meeting place is changed, and the recommended route 84 from the current position of the user to the meeting place is also changed. The recommended route to the waiting place after the change may be searched by the information management server 2 and the search result may be received in S16, or may be newly searched by the mobile information terminal 5.

  Next, in S18, the CPU 31 determines whether or not the mobile information terminal 5 is connected to the in-vehicle information terminal 7 and is in a communicable state. Note that, unlike S8, S18 is determined as “YES” while the mobile information terminal 5 is connected to the in-vehicle information terminal 7.

  And when it determines with the mobile information terminal 5 being connected with the vehicle-mounted information terminal 7 and being in the state which can communicate (S18: YES), it transfers to S19. On the other hand, when it is determined that the mobile information terminal 5 is not in a state where it can communicate with the in-vehicle information terminal 7 (S18: NO), the process proceeds to S20.

  In S19, the CPU 31 transmits information (facility ID, facility name, position coordinates, etc.) specifying the changed meeting place received in S16 to the in-vehicle information terminal 7 connected thereto. As a result, as will be described later, in the in-vehicle information terminal 7, the changed meeting place is set as a new destination, and travel guidance based on the searched guide route to the new destination is performed. However, as described later, when a destination is already set for the in-vehicle information terminal 7 and the destination is a destination set based on a user operation on the in-vehicle information terminal 7, the destination (That is, the new meeting place transmitted from the mobile information terminal 5 is not set as the destination, and the currently set destination is maintained). The processing of the in-vehicle information terminal 7 will be described later.

  Thereafter, in S20, the CPU 31 determines whether or not the waiting has been completed. Note that whether or not the waiting has been completed is determined by whether or not the positions of all the users 4 included in the group to be waiting have been matched. Note that the mobile information terminal 5 or the information management server 2 may determine whether or not the positions of all the users 4 included in the group to wait for match. Then, when the positions of all the users 4 included in the group to wait for match, it is determined that the waiting has been completed.

  If it is determined that the waiting has been completed (S20: YES), the waiting information providing program is terminated. On the other hand, when it is determined that the waiting has not been completed (S20: NO), the process returns to S8, and guidance is continuously performed based on the newly acquired current positions of the own user and other users. .

  If it is determined that the user has arrived at the meeting place and the other user has not reached the meeting place, the recommended route from the meeting place to the current position of the other user is guided. It may be configured.

Next, a waiting information providing program executed in the information management server 2 will be described with reference to FIGS.
First, in S <b> 21, the CPU 21 receives the waiting request information transmitted from the mobile information terminal 5. Note that the waiting request information includes information for specifying the “password” and the “waiting place” as described above. Also, the information management server 2 that has received the meeting request information updates the meeting place information 17 in the meeting management information DB 15 and registers the meeting place desired by the user.

  Next, in S <b> 22, the CPU 21 receives the “password” transmitted from the mobile information terminal 5 together with information (user ID or the like) specifying the user 4 who is the sender.

  Subsequently, in S23, the CPU 21 specifies the user 4 included in the group to perform the waiting based on the waiting request information received in S21 and the “password” received in S22. Specifically, the “password” input as the waiting request information is specified as the user 4 included in the group in which the user who has correctly input the meeting.

  Thereafter, in S24, the CPU 21 transmits information (facility ID, facility name, position coordinates, etc.) specifying the meeting place to the mobile information terminal 5 carried by each user specified in S23.

  Subsequently, in S25, the CPU 21 transmits a position information request to the mobile information terminal 5 carried by each user specified in S23. The position information request is a signal for requesting the current position of the user.

  After that, in S26, the CPU 21 receives the current position information transmitted from the mobile information terminal 5 of each user who waits in response to the position information request transmitted in S25.

  In S27, the CPU 21 updates the position management information 18 of the meeting management information DB 15 based on the received current position information. Specifically, the current position of the mobile information terminal 5 transmitted from each mobile information terminal 5 is specified as the current position of the user carrying the mobile information terminal 5 and stored in the meeting management information DB 15.

  Next, in S28, the CPU 31 refers to the location management information 18 in the waiting management information DB 15, and for each user included in the group that performs the waiting specified in S23, the current status of all users included in the group is determined. Send location information. In addition, it is good also as a structure which does not transmit about the user's own positional information used as a transmission destination. As a result, in the mobile information terminal 5 carried by each user who waits as described above, the position of the own user, the position of other users, and the like are displayed in addition to the meeting place (FIG. 7).

  Subsequently, in S <b> 29, the CPU 21 receives the waiting change information transmitted from the mobile information terminal 5. Note that the waiting change information includes information for specifying the waiting place after the change as described above.

  Next, in S30, the CPU 21 updates the meeting place information 17 in the meeting management information DB 15 and registers the changed meeting place. That is, the meeting place managed in the information management server 2 is changed.

  Thereafter, in S31, the CPU 21 transmits information (facility ID, facility name, position coordinates, etc.) for specifying the changed meeting place to the mobile information terminal 5 carried by each user specified in S23. As a result, the mobile information terminal 5 carried by each user who waits as described above performs guidance based on the changed waiting place (FIG. 8).

  Next, a waiting information providing program executed in the in-vehicle information terminal 7 constituting the information providing system 1 will be described with reference to FIG. FIG. 9 is a flowchart of the waiting information providing program according to the present embodiment. Here, the meeting information provision program is a program that is executed when information about a meeting place is transmitted from the mobile information terminal 5 and provides the user 4 with information necessary for meeting. The program shown in the flowchart in FIG. 9 below is stored in a RAM, a ROM, or the like provided in the in-vehicle information terminal 7 and is executed by the CPU 71.

  First, in S41, the CPU 71 receives a meeting place (current destination of the mobile information terminal 5) transmitted from the mobile information terminal 5. The meeting place moves after the meeting place is set and when the connection between the mobile information terminal 5 and the in-vehicle information terminal 7 is started (S9) and when the meeting place is changed (S19). It is transmitted from the information terminal 5.

  Next, in S <b> 42, the CPU 71 determines whether or not a destination has already been set in the in-vehicle information terminal 7.

  And when it determines with the destination already having been set in the vehicle-mounted information terminal 7 (S42: YES), it transfers to S43. On the other hand, when it determines with the destination not being set in the vehicle-mounted information terminal 7 (S42: NO), it transfers to S45.

  In S <b> 43, the CPU 71 acquires the destination currently set in the in-vehicle information terminal 7.

  Subsequently, in S44, the CPU 71 determines whether or not the destination currently set in the in-vehicle information terminal 7 acquired in S43 is a meeting place transmitted from the mobile information terminal 5 last time. In the in-vehicle information terminal 7 according to the present embodiment, when the meeting place is transmitted from the mobile information terminal 5 without setting the destination, the transmitted meeting place is set as the destination (S45). However, the user can change the destination to an arbitrary place by performing an operation on the in-vehicle information terminal 7 thereafter. Therefore, in S44, it is determined whether or not the destination currently set in the in-vehicle information terminal 7 is the destination set by the operation of the user 4 with respect to the in-vehicle information terminal 7.

  And when it is determined that the destination currently set in the in-vehicle information terminal 7 is a meeting place transmitted from the mobile information terminal 5 last time (S44: YES), that is, in the in-vehicle information terminal 7, the current setting When it is determined that the set destination is not the destination set by the operation of the user 4, the process proceeds to S45.

  On the other hand, when it is determined that the destination currently set in the in-vehicle information terminal 7 is not the meeting place transmitted from the mobile information terminal 5 last time (S44: NO), that is, the in-vehicle information terminal 7 is currently set. If it is determined that the current destination is the destination set by the operation of the user 4, the meeting place received in S41 is not set as the destination (that is, the destination is not changed). Then, the waiting information providing program is terminated. As a result, the in-vehicle information terminal 7 continues to perform travel guidance based on the existing destination and the guidance route to the destination.

  On the other hand, in S45, the CPU 71 sets the meeting place received in S41 as the destination of the in-vehicle information terminal 7. In particular, when the destination is already set in the in-vehicle information terminal 7, the destination is changed to the meeting place received in S41. However, when the meeting place received in S41 is the same place as the destination currently set in the in-vehicle information terminal 7, the destination changing process is not performed.

  Thereafter, in S46, the CPU 71 starts traveling guidance based on the new destination set in S45. Specifically, a route from the current position of the user to a new destination is searched, and a guide route to the new destination is set based on the search result. Then, the set guidance route is displayed and guidance such as turning right and left is performed so as to travel along the guidance route.

  In addition, the position of the own user may be acquired from the mobile information terminal 5, or the position of the own user specified in the in-vehicle information terminal 7 may be guided. Moreover, you may comprise so that the location information of the other user included in the group which waits may be received from the mobile information terminal 5, and the location of the other user may be guided. As a result, in addition to the meeting place, it is possible to grasp the own position and the position of the meeting partner.

Here, FIG. 10 is a diagram showing an example of a travel guidance screen 90 displayed on the liquid crystal display 55 of the in-vehicle information terminal 7.
As shown in FIG. 10, the liquid crystal display 55 has a map image 91 around the user, a current location mark 92 indicating the current location of the user, and the currently set destination (the meeting location in S45 is the destination). Destination mark 93 for specifying the destination), a guide route 94 from the current position of the user to the destination, and a partner for specifying the current position of the other user who is the meeting partner A mark 95 is displayed. In addition, when there are a plurality of other users who are waiting parties, the partner mark 95 displays the positions of the plurality of other users. As a result, the user can grasp the route to the meeting place and the current position of the meeting partner in addition to the meeting place by referring to the travel guide screen 90 displayed on the liquid crystal display 55. If the in-vehicle information terminal 7 provides travel guidance based on the guide route 94 from the current position of the user to the meeting place, the user can be more reliably guided to the meeting place.

  In addition, in the case where the in-vehicle information terminal 7 has set the meeting place transmitted last time from the mobile information terminal 5 as the destination, the meeting place is changed after that and the new meeting place is changed to the moving information terminal. If it is transmitted from 5, the destination is changed in S45. As a result, the guide route that has been displayed as shown in FIG. 11 is temporarily deleted, and a new guide route with the changed meeting place as the destination is displayed.

  On the other hand, for example, when the user operates the in-vehicle information terminal 7 to change the destination from the meeting place transmitted from the mobile information terminal 5 last time, the meeting place is changed after that and the new change is made. When a later meeting place is transmitted from the mobile information terminal 5, the destination changing process in S45 is not performed. As a result, the destination and the guidance route are not changed as shown in FIG.

  Further, when it is determined “NO” in S44, that is, when the destination of the in-vehicle information terminal 7 is not changed to the meeting place received in S41, the destination of the in-vehicle information terminal is determined by the mobile information terminal 5. It is desirable to have a configuration that allows the user to confirm whether or not to make the change. For example, as shown in FIG. 13, a confirmation window 96 is newly displayed on the display 38 of the mobile information terminal 5 to allow the user to select whether or not to change the destination of the in-vehicle information terminal 7. And when a user chooses to change the destination of the vehicle-mounted information terminal 7, it transfers to S45. That is, the destination is changed to the meeting place received in S41, and the travel guidance is started based on the set new destination. As a result, even if the destination setting operation performed by the user is canceled, the destination of the in-vehicle information terminal 7 can be set as a meeting place if the user desires. It is possible to make travel guidance along the line.

  As described in detail above, the vehicle information terminal 7, the information providing system 1, the destination setting method in the vehicle information terminal 7 and the computer program executed in the vehicle information terminal 7 according to the present embodiment are communicably connected. When information about the meeting place which is the destination set in the mobile information terminal 5 is acquired from the mobile information terminal 5 (S41), it is determined whether the destination is already set in the in-vehicle information terminal 7 ( S42), it is determined that the destination is already set in the in-vehicle information terminal, and that the set destination is the destination set by the user's operation to the in-vehicle information terminal 7. In this case, the currently set destination in the in-vehicle information terminal 7 is not changed. On the other hand, even when the destination is not set in the in-vehicle information terminal or when the destination is set, the set destination is the waiting place transmitted from the mobile information terminal 5 last time. In some cases, the destination of the in-vehicle information terminal 7 is set as the newly acquired meeting place (S45, S46), so the destination of the in-vehicle information terminal 7 is set based on the information transmitted from the mobile information terminal 5 On the other hand, the destination setting operation ignoring the user's intention is performed by respecting the on-vehicle information terminal 7 with respect to the destination setting operation performed by the user's own intention. This can be prevented. As a result, for example, it is possible to prevent a destination setting operation performed by the user himself from being canceled against the user's intention.

Note that the present invention is not limited to the above-described embodiment, and various improvements and modifications can be made without departing from the scope of the present invention.
For example, in this embodiment, the mobile information terminal 5 executes the processes of S1 to S20 of the waiting information providing program (FIGS. 5, 6, and 9), the information management server 2 executes the processes of S21 to S31, and S41. The in-vehicle information terminal 7 executes the processing of ~ S46, but the main body that executes each step can be appropriately changed among the three parties.

  In the present embodiment, communication between the mobile information terminal 5 and the in-vehicle information terminal 7 is performed by wireless communication using Bluetooth, but may be wireless communication of other standards. Alternatively, the mobile information terminal 5 and the in-vehicle information terminal 7 may be connected by cable communication or the like.

  The in-vehicle information terminal 7 may have means for communicating with the communication network 8. In that case, communication between the mobile information terminal 5 and the in-vehicle information terminal 7 may be performed by Bluetooth or may be performed via the communication network 8.

  Further, in the present embodiment, in addition to the case where the meeting place is changed, even when the meeting place is first transmitted from the mobile information terminal 5 to the in-vehicle information terminal 7 in addition to the case where the meeting place is changed, S42 to S44. Although it is configured to determine whether or not to set the meeting place as the destination by the determination process, the determination process of S42 to S44 may be executed only when the meeting place is changed. As a result, if the meeting place is first transmitted from the mobile information terminal 5 to the in-vehicle information terminal 7 after the start of the waiting, the transmission is performed no matter what destination is set in the in-vehicle information terminal 7 The designated meeting place is always set as the destination (S45, S46).

  Further, in the present embodiment, an example in which the information providing system is applied as a system that provides information on the current position and meeting place of each user belonging to the group to a group of a plurality of users who have been waiting has been described. Other applications are possible. For example, the present invention can be applied as a system in which a user who has both the mobile information terminal 5 and the in-vehicle information terminal 7 shares a destination among the information terminals. In that case, for example, when the user who has traveled to the destination with the mobile information terminal 5 gets on the vehicle 6 on the way, the in-vehicle information terminal 7 does not perform the destination setting operation. The information terminal 7 can continuously receive travel guidance to the destination.

  Moreover, although this embodiment demonstrated the example applied to the destination setting of the vehicle-mounted information terminal 7, you may apply to the destination setting of the mobile information terminal 5. FIG. In this case, for example, when a meeting place is transmitted from the in-vehicle information terminal 7 or a mobile information terminal possessed by another user, whether or not the meeting place is set as the destination of the movement information terminal 5 is determined after S42. It is set as the structure determined by the process of.

  In addition, the embodiment in which the information providing system and the information terminal according to the present invention are embodied has been described above. However, the information providing system and the information terminal can also have the following configurations, and in that case, the following effects can be obtained. Play.

For example, the first configuration is as follows.
The first destination setting means is a case where the own terminal destination is already set in the information terminal, and the set own terminal destination is different from the newly acquired other terminal destination. And if it is the destination set by the first destination setting means, it changes the own terminal destination to the newly acquired other terminal destination.
According to the information terminal having the above configuration, when a destination set based on information transmitted from another information terminal in the past is still set as a destination of the information terminal at this time, the other information terminal It becomes possible to set the destination based on information newly transmitted from. Therefore, it is possible to set a more appropriate destination based on newly acquired information without performing a destination setting operation ignoring the user's intention.

For example, the second configuration is as follows.
The other terminal destination set in the mobile information terminal is a meeting place between the user and another user, and the mobile information terminal is connected to the in-vehicle information terminal after the meeting place is set. When the case and the meeting place are changed, the information on the other terminal destination is transmitted to the in-vehicle information terminal.
According to the information providing system having the above configuration, when a user waits with another user, the meeting place can be set as a destination of the in-vehicle information terminal without particularly performing an operation on the in-vehicle information terminal. It becomes possible. As a result, even when the user goes to the meeting place with the vehicle, it is possible to appropriately guide to the meeting place without imposing a new operation burden on the user.

The third configuration is as follows.
The mobile information terminal transmits information related to the other terminal destination set in the mobile information terminal to the in-vehicle information terminal, and the in-vehicle information terminal changes the own terminal destination by the first destination setting means. If not, the in-vehicle information terminal allows the user to select whether or not to change its own terminal destination to another terminal destination. When it is selected to change to the destination, the first destination setting means changes the own terminal destination to another terminal destination.
According to the information providing system having the above configuration, even if the destination setting operation performed by the user is canceled, if the user desires, the destination of the in-vehicle information terminal is set as a meeting place. It becomes possible for the user to perform travel guidance according to the intention.
