Further, in order for the automobile equipped with the route search device 50 to go to the periphery of the terminal device 30, the current destination or the like is set based on the position information of the terminal device 30. However, in order for the terminal device 30 to go to the periphery of the route search device 50, the current destination or the like may be set based on the position information 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 current destination and the position of the terminal device 30. The new destination setting unit 14 may set a new destination based on the position of the route search device 50.

In the first embodiment, the reference distance B has been described as determining the distance between the current destination and the new destination according to the distance A between the current destination and the route search device 50. The reference distance B may determine the distance between the current destination and the new destination according to the time T required for the vehicle equipped with the route search device 50 to arrive at the current destination.

Since the reference distance B according to the required times T1 to T5 is the same as that in the first embodiment, the description thereof will be omitted.

Similar to 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 preferable to set the current destination setting unit 13 so that the interval for transmitting the position information of the current destination is longer.

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 according to the required time T for the reference distance B 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 explanation.

In FIG. 9, steps S101 to 104, steps S106 to 108, and steps S110 to 111 are the same as the processing of the first embodiment, and thus the 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 it is determined that the required time T is within the T1 range (step S105: Y), the current destination It is determined whether the distance between the new destination and the new destination is equal to or greater than the reference distance B1 (step S106).

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

When the current destination setting unit 13 determines 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 equal to or greater than the reference distance B2 (step). S111).

When the current destination setting unit 13 determines 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. (Step S111).

By determining the reference distance B according to the required time T in this way, if the required time T becomes shorter, the current destination is frequently transmitted from the current destination setting unit 13, while the required time T becomes longer. Therefore, the frequency with which the current destination is transmitted from the current destination setting unit 13 decreases. Therefore, even when the distance A is short due to traffic jams or the like, the current destination is not frequently transmitted from the current destination setting unit 13, and the usability of the user can be enhanced.

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

Specifically, as shown in FIG. 10, the route search device 50 serves as a functional block of the control unit 51 with the position acquisition unit 56, the current destination setting unit 57, the new destination setting unit 58, and the 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 parts 56, 57, 58, 59, 60 has the same function as that of the first embodiment, the description thereof will be omitted. Further, the process of setting the new destination as the current destination and generating the route information by the route search device 50 is the same as that of the first embodiment, and thus the description thereof will be omitted.

The terminal device 30 and the route search device 50 are connected to each other so as to be able to communicate with each other via wireless communication, for example, and data is directly exchanged between the terminal device 30 and the route search device 50 without going through the server 10. May be processed.

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

Specifically, as shown in FIG. 11, the terminal device 30 sets the position acquisition unit 36, the current destination setting unit 37, the new destination setting unit 38, and the reference distance as functional blocks of the control unit 31. 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, the description thereof will be omitted. Further, the process of setting the new destination as the current destination and generating the route information by the terminal device 30 is the same as that of the first embodiment, and thus the description thereof will be omitted.

As described in the second embodiment, the processing may be performed by directly exchanging data between the terminal device 30 and the route search device 50 without going through the server 10.

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 more than the reference distance. The current destination may be set when the reference time has elapsed from the time when the current destination is set.

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

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.

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

For the reference time S according to the distances A1 to A5, the reference distance when the distance is A1 is S1 (15 seconds), the reference time S when the distance is S2 is S2 (30 seconds), and the reference time when the distance is A3. S is defined as S3 (60 seconds), the reference time S at a distance A4 is defined as S4 (120 seconds), and the reference time S at a distance A5 is defined as S5 (300 seconds).

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

In this way, in 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.

Just as the reference distance A is set according to the required time T, the reference time S may be 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 times T1 to T5. Since the numerical values of T1 to T5 and S1 to S5 are the same as those described above, the description thereof will be omitted.

In the route guidance system 100 described above, the process of displaying the route information regarding the new destination on the display unit 52 by the route search device 50 will be described with reference to the flow chart shown in FIG.

In this 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 explanation.

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

In step S205, when 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).

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

When the current destination setting unit 13 determines in the determination of 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 S206: Y). Step S207). Since the subsequent processing is the same as that of the first embodiment, the description thereof will be omitted.

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

In step S210, when the current destination setting unit 13 determines 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 the determination of step S211 that the reference time S2 has not elapsed (step S211: N), the process returns to the process of step S203.

When the current destination setting unit 13 determines in the determination of 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 S211: Y). Step S212). Since the subsequent processing is the same as that of the first embodiment, the description thereof will be omitted.

In step S210, when the current destination setting unit 13 determines 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 the determination of step S213 that the reference time S3 has not elapsed (step S213: N), the process returns to the process of step S203.

When the current destination setting unit 13 determines in the determination of 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 S213: Y). Step S214). Since the subsequent processing is the same as that of the first embodiment, the description thereof will be omitted.

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