  The conditions for setting the upload frequency include, for example, the condition that uploading is not performed until a certain time has elapsed after the position information was acquired, the condition that uploading is not performed if the position information is acquired within a certain range from the previously acquired position information, etc. Is mentioned.

  For uploading the position information, for example, each of the devices 30 and 50 may upload the position information in response to a request from the server 10.

  The trigger for starting the following process performed by the server 10 may be when the server 10 is powered on or when position information is acquired from the terminal device 30 and the route search device 50.

  The position acquisition unit 12 of the server 10 determines whether the position information uploaded from the terminal device 30 and the route search device 50 has been acquired (step S01). This determination is repeated until it is determined that the position information has been acquired.

  When it is determined in step S01 that the position information has been acquired (step S01: Y), the current destination setting unit 13 sets the current destination based on the acquired position information of both devices (step S02).

  Here, the route information generation unit 16 may generate route information from the current position of the route search device 50 to the current destination, and the route information may be transmitted to the route search device 50.

  The position acquisition unit 12 determines whether or not position information is newly acquired after the process of step S01 (step S03). This determination is repeated until it is determined that the position information is newly acquired.

  When it is determined in step S03 that the position information has been acquired (step S03: Y), the new destination setting unit 14 determines the new destination based on the position information of the terminal device 30 newly acquired in step S03. It is set (step S04).

S05: Y), it is determined whether the distance between the current destination and the new destination is the reference distance B1 or more (step S06).

  When it is determined in step S06 that the distance is equal to or greater than the reference distance B1 (step S06: Y), the current destination setting unit 13 sets the new destination set in step S04 as the current destination. (Step S07).

  The current destination setting unit 13 transmits the position information of the current destination set in step S07 to the route search device 50 (step S08).

  Here, the route information generation unit 16 generates route information from the current position of the route search device 50 to the current destination, and the route information is transmitted to the route search device 50 together with the position information of the current destination. May be.

  When it is determined in step S05 that the distance A is not within the A1 range (step S05: N), the current destination setting unit 13 determines whether the distance A is within the A2 range (step S09).

  When determining that the distance A is within the A2 range (step S09: Y), the current destination setting unit 13 determines whether the distance between the current destination and the new destination is the reference distance B2 or more (step S10). ).

  In the determination in step S10, when the current destination setting unit 13 determines that the distance is equal to or greater than the reference distance B2 (step S10: Y), the new destination set in step S04 is set as the current destination. (Step S07), the current destination set in step S07 is transmitted to the route search device 50 (step S08).

  In the determination of step S10, when the current destination setting unit 13 determines that the distance between the current destination and the new destination is not the reference distance B2 or more (step S10: N), the process returns to the position acquisition determination of step S03.

  When it is determined in step S09 that the distance A is not within the A2 range (step S09: N), the current destination setting unit 13 determines whether the distance between the current destination and the new destination is B3 or more. (Step S11).

  In the determination of step S11, when the current destination setting unit 13 determines that the distance between the current destination and the new destination is B3 or more (step S11: Y), the new destination set in step S04 is set. The current destination set in step S07 is set to the current destination (step S07), and the current destination set in step S07 is transmitted to the route search device 50 (step S08).

  When it is determined in step S11 that the distance between the current destination and the new destination is not B2 or more (step S11: N), the current destination setting unit 13 returns to the position acquisition determination in step S03.

  The above process may be repeatedly executed. Further, in order to reduce the processing load on the server 10, conditions for re-executing the above processing may be provided. The conditions for re-executing the process include, for example, the condition that the process is not performed until a predetermined time has elapsed from the time when the position information was uploaded from each device 30, 50.

  The route search device 50 displays the current destination on the display unit 52 based on the position information of the current destination. When the route information is received in addition to the position information of the current destination, the display unit 52 displays the current destination together with the route information.

  Here, when the route search device 50 receives the information about the current destination from the server 10 when the vehicle equipped with the route search device 50 is in the vicinity of the intersection, the route information is updated during execution of the right / left turn. In order to prevent this, the current destination may be presented when passing the intersection.

  It should be noted that a condition for displaying the current destination may be provided in order to reduce the inconvenience caused by frequent route guidance by the route search device 50 and to reduce the processing load of the guidance device.

  As conditions for displaying the current destination, for example, (1) route guidance processing is not performed for a certain period of time on the information of the current destination transmitted from the server 10, (2) guidance start permission / non-permission button Is provided and the user selects the display timing, and the like.

  When the distance A between the route search device 50 and the current destination becomes, for example, 50 m or less, the route search device 50 ends the guidance guidance.

  The guidance guidance process may be ended by stopping the upload process of the position information of each of the devices 30 and 50.

  The uploading process may be stopped, for example, by the user pressing the “Stop transmitting position information” button displayed on the display unit 32 of the terminal device 30, as shown in FIG. 2.

  Alternatively, the upload processing may be stopped by each of the devices 30 and 50 receiving a guidance end notification from the server 10.

  The server 10 may transmit the position information of the route search device 50 to the terminal device 30, and the information may be shared between the terminal device 30 and the route search device 50.

  For example, as shown in FIG. 6A, when the user presses the “vehicle position information” button, the terminal device 30 transmits the position information and the like of the vehicle in which the route search device 50 of the vehicle is mounted to the server 10. To request.

  The terminal device 30, which has received the position information and the like, displays, for example, the estimated arrival time of the vehicle and the required time of the vehicle on the display unit 32 such as the position of the vehicle on which the route search device 50 is mounted, as shown in FIG. 6B. indicate.

  In this way, the user of the terminal device 30 can know the current location of the automobile and the estimated arrival time, and can make an action plan in accordance with the arrival time, thereby enhancing the usability of the user.

  As described above, according to the information processing device of the present invention, it is possible to present information to the user at an appropriate timing according to the distance A between the route search device 50 and the terminal device 30.

  Therefore, it is possible to eliminate the troublesomeness of being notified of the change of the destination each time the position of the terminal device 30 is updated. Therefore, the information processing device of the present invention can enhance the usability of the user.

  In this embodiment, the route search device 50 may generate the route information to the current destination.

  When the route search device 50 generates route information, the control unit 51 of the route search device 50 is provided with the route information generation unit 16 as a functional block. The route information generation unit 16 may generate the route information based on the position information of the current destination transmitted from the server 10.

  Further, since the automobile equipped with the route search device 50 heads to the vicinity of the terminal device 30, the current destination or the like is set based on the position information of the terminal device 30. However, the terminal device 30 may set the current destination or the like based on the position information of the route search device 50 so that the terminal device 30 moves toward the periphery of the route search device 50.

  In this case, the current destination setting unit 13 may set the current destination based on the position of the route search device 50. The reference distance setting unit 17 may set the reference distance based on the positions of the current destination and the terminal device 30. The new destination setting unit 14 may set the new destination based on the position of the route search device 50.

  In the first embodiment, the reference distance B is described as the distance between the current destination and the new destination determined according to the distance A between the current destination and the route search device 50. The reference distance B may be the distance between the current destination and the new destination determined according to the time T required for the vehicle equipped with the route search device 50 to reach the current destination.

  The reference distance setting unit 17 of the server 10 calculates the required time T until the vehicle equipped with the route search device 50 arrives at the current destination based on the current destination and the position of the route search device 50. The reference distance B is set based on the time T. Specifically, the reference distance setting unit 17 calculates the required time in consideration of the route of the general road or the highway through which the vehicle equipped with the route search device 50 is guided, and the congestion situation. The other configuration is the same as that of the first embodiment, and thus the description is omitted.

  When the reference distance B is set in this way, as shown in FIG. 7, for example, the reference distance B when the required time T corresponds to the required time T1 to T5 is set to B1 to B5.

  As the specific required time T, when the required time T is within 5 minutes, it is T1, when it is 5-10 minutes, it is T2, when it is 10-20 minutes, it is T3, when it is 20-40 minutes, it is T4, 40 minutes. The above time is defined as T5.

  The reference distance B corresponding to the required times T1 to T5 is the same as that in the first embodiment, and therefore its description is omitted.

  As in the case where the reference distance B is set according to the distance A, when the required time T is short, the current destination setting unit 13 frequently transmits the position information of the current destination, and the required time T becomes long. Therefore, it is advisable to set the current destination setting unit 13 to set a longer interval for transmitting the position information of the current destination.

  Hereinafter, a process in which the route search device 50 displays the route information regarding the current destination on the display unit 52 when the distance between the current destination and the new destination is determined by the reference distance B according to the required time T will be described.

  As shown in FIG. 8, in this example, the required time T is set to T1 to T3 and the reference distance B is set to B1 to B3 in order to simplify the description.

  In FIG. 9, steps S101 to S104, steps S106 to 108, and steps S110 to 111 are the same as the processing of the first embodiment, and a description thereof will be omitted.

  The current destination setting unit 13 determines whether the required time T is within the T1 range (step S105), and when the required time T is within the T1 range (step S105: Y), the current destination is determined. Then, it is determined whether the distance to the new destination is equal to or greater than the reference distance B1 (step S106).

  When determining that the required time T is not within the T1 range in the determination of step S105 (step S105: N), the current destination setting unit 13 determines whether the required time T is within the T2 range (step S109). ).

  When determining that the required time T is within the T2 range (step S109: Y), the current destination setting unit 13 determines whether the distance between the current destination and the new destination is the reference distance B2 or more (step S109). S111).

  When it is determined in step S109 that the required time T is not within the T2 range (step S109: N), the current destination setting unit 13 determines whether the distance between the current destination and the new destination is B3 or more. Yes (step S111).

  In this way, by determining the reference distance B according to the required time T, the shorter the required time T, the more frequently the current destination is transmitted from the current destination setting unit 13, while the longer the required time T. Accordingly, the frequency of transmitting the current destination from the current destination setting unit 13 decreases. For this reason, even if the distance A is short due to traffic congestion in the automobile, the current destination is not frequently transmitted from the current destination setting unit 13, and the user's usability can be improved.

  In the first and second embodiments, the server 10 performs the process of setting the new destination as the current destination. This processing may be performed by the route search device 50.

  Specifically, as shown in FIG. 10, the route search device 50 includes, as functional blocks of the control unit 51, a position acquisition unit 56, a current destination setting unit 57, a new destination setting unit 58, and a reference distance. It has a setting unit 59, a reference distance setting unit 59, and a route information generation unit 60.

  Since each of these units 56, 57, 58, 59, 60 has the same function as that of the first embodiment, a description thereof will be omitted. Further, the process in which the route search device 50 sets the new destination as the current destination and generates the route information is the same as that in the first embodiment, and therefore the description thereof is omitted.

  The terminal device 30 and the route search device 50 are communicably connected to each other, for example, via wireless communication, and data is directly exchanged between the terminal device 30 and the route search device 50 without the server 10. You may process it.

  In the first and second embodiments, the server 10 performs the process of setting the new destination as the current destination. This processing may be performed by the terminal device 30.

  Specifically, as shown in FIG. 11, the terminal device 30 has, as functional blocks of the control unit 31, a position acquisition unit 36, a current destination setting unit 37, a new destination setting unit 38, and a reference distance setting. It has a unit 39 and a route information generation unit 40.

  Since each of these parts 36, 37, 38, 39, 40 has the same function as that of the first embodiment, a description thereof will be omitted. Further, the process in which the terminal device 30 sets the new destination as the current destination and generates the route information is the same as that in the first embodiment, and therefore the description thereof is omitted.

  As described in the second embodiment, the data may be directly exchanged between the terminal device 30 and the route search device 50 without using the server 10 to perform the processing.

  In Examples 1 to 4, the current destination setting unit sets the new destination as the current destination when the distance between the current destination and the new destination becomes equal to or greater than the reference distance. The setting of the current destination may be performed when the reference time has elapsed from the time when the current destination was set.

  As shown in FIG. 12, the server 10 has, as a functional block of the control unit 11, a reference time setting unit 21 in addition to the above functional blocks.

  The reference time setting unit 21 sets the reference time S based on the distance between the current destination and the route search device 50 when the current destination is set.

  The reference time S is, for example, as shown in FIG. 13A, the elapsed time from the time when the current destination is set according to the distance A.

  As shown in FIG. 13A, the reference time S when the distance A corresponds to the distance A1 to A5 is set to S1 to S5. Since the distances A1 to A5 are the same as those in the first embodiment, description thereof will be omitted.

  As for the reference time S according to the distances A1 to A5, the reference distance when the distance A1 is S1 (15 seconds), the reference time S when the distance S2 is S2 (30 seconds), and the reference time when the distance A3 is used S is set to S3 (60 seconds), reference time S is set to S4 (120 seconds) when the distance is A4, and reference time S is set to S5 (300 seconds) when the distance is A5.

  Therefore, for example, when the distance A corresponds to the distance A5 which is 10 km or more away, when the 300 seconds or more corresponding to the reference time S5 elapses, the current destination setting unit 13 sets the route to the newly set current destination. It is set to be transmitted to the search device 50.

  Thus, for the reference time S, the current destination setting unit 13 frequently transmits the current destination when the distance A is short, and the current destination setting unit 13 transmits the current destination as the distance A becomes longer. It is advisable to set the interval to be longer.

  The reference time S may be set according to the required time T, as the reference distance A is set according to the required time T.

  For example, as shown in FIG. 13B, the reference time S can be set to S1 to S5 according to the required time T1 to T5. Since the numerical values of T1 to T5 and S1 to S5 are the same as the above description, the description will be omitted.

  In the route guidance system 100 described above, the process in which the route search device 50 displays the route information regarding the new destination on the display unit 52 will be described based on the flowchart shown in FIG.

  In the present embodiment, as shown in FIG. 13C, the distance A is set to A1 to A3 and the reference time S is set to S1 to S3 in order to simplify the description.

  In FIG. 14, steps S201 to S205 correspond to steps S01 to S05 of the process described in the first embodiment, and therefore description thereof will be omitted.

  In step S205, if the current destination setting unit 13 determines that the distance A is within the range of A1 (step S205: Y), it determines whether the reference time S1 has elapsed (step S206).

  If the current destination setting unit 13 determines in step S206 that the reference time S1 has not elapsed (step S206: N), the process returns to step S203.

  When it is determined in step S206 that the reference time S1 has elapsed (step S206: Y), the current destination setting unit 13 determines whether the distance between the current destination and the new destination is B1 or more ( Step S207). Subsequent processing is the same as that of the first embodiment, and therefore its explanation is omitted.

  In the determination of step S205, if the current destination setting unit 13 determines that the distance A is not within the range of A1 (step S205: N), it is determined whether the distance A is within the range of A2 (step S210).

  When it is determined in step S210 that the distance A is within the range of A2 (step S210: Y), the current destination setting unit 13 determines whether the reference time S2 has elapsed (step S211).

  When it is determined in step S211 that the reference time S2 has not elapsed (step S211: N), the process returns to step S203.

  When it is determined in step S211 that the reference time S2 has elapsed (step S211: Y), the current destination setting unit 13 determines whether the distance between the current destination and the new destination is B2 or more ( Step S212). Subsequent processing is the same as that of the first embodiment, and therefore its explanation is omitted.

  In step S210, when it is determined that the distance A is not within the range of A2 (step S210: N), the current destination setting unit 13 determines whether the reference time S3 has elapsed (step S213).

  When it is determined in step S213 that the reference time S3 has not elapsed (step S213: N), the process returns to step S203.

  When it is determined in step S213 that the reference time S3 has elapsed (step S213: Y), the current destination setting unit 13 determines whether the distance between the current destination and the new destination is B3 or more ( Step S214). Subsequent processing is the same as that of the first embodiment, and therefore its explanation is omitted.

  In the fifth embodiment, the server 10 performs the process of setting the new destination as the current destination. This processing may be performed by the route search device 50.

  As shown in FIG. 15, the route search device 50 has, as a functional block of the control unit 51, a reference time setting unit 61 in addition to the above functional blocks.

  The other structure is the same as that of the fourth embodiment, and the description thereof is omitted. Further, since this processing is also the same as that of the fifth embodiment, the description thereof will be omitted.

  In the fifth to seventh embodiments, the control units 11, 51 and 31 are provided with the reference distance setting units 17, 61 and 41 as one of the functional blocks, but the reference distance setting units 17, 61 and 41 are excluded. You may implement it. In that case, the process of step S207, step S212, and step S214 of the flowchart shown in FIG. 14 is not performed, but the process is performed.

  In addition, the functional blocks of the control units 11, 31, and 51 described above include any of the control units 11, 31, and 51, and any one of the devices 10, 30, and 50 performs the processing described above. You may make it appropriate.
