Association system, in-vehicle device, association method

1. An association system comprising:

an in-vehicle device,

a portable terminal, and

a server,

wherein the in-vehicle device comprises:

an in-vehicle storage unit which stores an in-vehicle device ID as an identifier for identifying the in-vehicle device;

a first communication unit which broadcasts the in-vehicle device ID to the portable terminal via a beacon payload;

a vehicle position acquisition unit which acquires a vehicle position as a position of the in-vehicle device; and

a second communication unit which sends the in-vehicle device ID and the vehicle position to the server,

wherein the portable terminal comprises:

a portable storage unit which stores a portable terminal ID as an identifier for identifying the portable terminal;

a portable terminal position acquisition unit which acquires a portable terminal position as a position of the portable terminal; and

an authentication information sending unit which sends, to the server, authentication information including the portable terminal ID, the received in-vehicle device ID, and the portable terminal position, and

wherein the server comprises:

an association unit which determines whether a difference between the portable terminal position included in the received authentication information and the received vehicle position is within a predetermined range; and when the difference is within the predetermined range and a difference of received time of the authentication information and the vehicle position are within a predetermined time, associates the portable terminal ID and the in-vehicle device ID.

2. The association system according to claim 1 , wherein the server further comprises:

a key database which stores key information corresponding to each of the in-vehicle devices; and

a key sending unit which sends, to the portable terminal having the portable terminal ID which was associated by the association unit, the key information corresponding to the in-vehicle device 1 D which was associated by the association unit.

3. The association system according to claim 2 , wherein the server further comprises:

an administrator database which stores contact information of an administrator corresponding to each of the in-vehicle device IDs; and

a verification unit which, when the association unit performs association, refers to the administrator database and identifies the contact information of the administrator corresponding to the in-vehicle device ID which was associated by the association unit, sends an approval inquiry for issuing the key information to the identified contact information of the administrator, and, when a positive reply is obtained from the administrator, sends the key information to the key sending unit.

4. The association system according to claim 1 , wherein the server further comprises: a parking position sending unit which sends, to the portable terminal having the portable terminal ID which was associated by the association unit, position information which was last received from the in-vehicle device having the in-vehicle device ID which was associated by the association unit.

5. The association system according to claim 1 , wherein the server further comprises: an authenticated ID sending unit which sends, to the in-vehicle device having the in-vehicle device ID which was associated by the association unit, the portable terminal ID which was associated by the association unit.

6. The association system according to claim 1 , wherein the authentication information sending unit of the portable terminal sends the authentication information in at least one of either a case when sending of the in-vehicle device ID from the in-vehicle device is interrupted and a case when sending of the in-vehicle device 1 D from the in-vehicle device reaches a predetermined number of times.

7. The association system according to claim 1 , wherein the first communication unit of the in-vehicle device sends the in-vehicle device ID when a speed of a vehicle equipped with the in-vehicle device falls below a predetermined speed.

8. An association method executed in an in-vehicle device, a portable terminal, and a server, comprising the steps of:

by the in-vehicle device:

storing an in-vehicle device ID as an identifier for identifying the in-vehicle device;

broadcasting the in-vehicle device ID to the portable terminal via a beacon payload;

calculating a vehicle position as a position of the in-vehicle device; and

sending the in-vehicle device ID and the vehicle position to the server, and by the portable terminal:

storing a portable terminal ID as an identifier for identifying the portable terminal;

calculating a portable terminal position as a position of the portable terminal;

receiving the in-vehicle device ID from the in-vehicle device without any operation of the portable terminal by a user within the predetermined communication range; and

sending, to the server, authentication information configured from the portable terminal ID, the received in-vehicle device ID, and the portable terminal position,

determining, by the server, whether a difference between the received portable terminal position and the received vehicle position is within a predetermined range; and when a difference is within the predetermined range and a difference of received time of the authentication information and the vehicle position are within a predetermined time, the server associates the portable terminal ID and the in-vehicle device ID.

9. The association method according to claim 8 , further comprising the steps of:

by the server:

storing a key database which stores key information corresponding to each of the in-vehicle devices; and

sending the key information corresponding to the associated the in-vehicle device ID to the portable terminal having the associated portable terminal ID.

10. The association method according to claim 9 , further comprising the steps of:

by the server:

storing an administrator database which stores contact information of an administrator corresponding to each of the in-vehicle device IDs; and

when the association is performed, referring to the administrator database and identifying the contact information of the administrator corresponding to the associated in-vehicle device ID, sending an approval inquiry for issuing the key information to the identified contact information of the administrator, and, when a positive reply is obtained from the administrator, sending the key information.

11. The association method according to claim 8 , further comprising the step of:

by the server:

sending position information which was last received from the in-vehicle device having the associated in-vehicle device ID to the portable terminal having the associated portable terminal ID.

12. The association method according to claim 8 , further comprising the step of:

by the server:

sending the associated portable terminal ID to the in-vehicle device having the associated in-vehicle device ID.

13. The association method according to claim 8 , wherein the portable terminal sends the authentication information in at least one of either a case when sending of the in-vehicle device ID from the in-vehicle device is interrupted and a case when sending of the in-vehicle device ID from the in-vehicle device reaches a predetermined number of times.

14. The association method according to claim 8 , wherein the in-vehicle device sends the in-vehicle device ID when a speed of a vehicle equipped with the in-vehicle device falls below a predetermined speed.
