Abstract

A driving assistance apparatus includes a storage configured to store map information; and a communication device configured to transmit location information to a second driving assistance apparatus at predetermined time periods, wherein the communication device transmits the map information to the second driving assistance apparatus if a target of the map information changes.

Claims

1. A driving assistance apparatus comprising:

a storage configured to store map information; and

a communication device configured to transmit location information to a second driving assistance apparatus at predetermined time periods,

wherein the communication device transmits the map information to the second driving assistance apparatus if a target of the map information changes.

2. The driving assistance apparatus of claim 1, wherein if the target is found within a predetermined spatial range, the communication device transmits map information for the target to the second driving assistance apparatus.

3. The driving assistance apparatus of claim 2, wherein if the target is found within the predetermined spatial range, the communication device transmits the map information for the target and information about the predetermined spatial range to the second driving assistance apparatus.

4. The driving assistance apparatus of claim 2, wherein the storage stores a plurality of pieces of map information, and the predetermined spatial range is set for a target of each piece of the map information.

5. The driving assistance apparatus of claim 1, wherein if the target of the map information changes, the communication device transmits at least one of information about a distance to the changed target and information about an estimated time of arrival at the changed target to the second driving assistance apparatus.

6. The driving assistance apparatus of claim 5, further comprising a controller configured to calculate at least one of the distance to the changed target and the estimated time of arrival at the changed target.

7. The driving assistance apparatus of claim 1, wherein if the target of the map information changes, the communication device transmits the map information to the second driving assistance apparatus at a next transmission time of the location information.

8. The driving assistance apparatus of claim 7, further comprising a controller configured to calculate at least one of a distance between the changed target and the driving assistance apparatus and an estimated time of arrival at the changed target,

wherein the controller calculates at least one of the distance between the changed target and the driving assistance apparatus at the next transmission time of the location information and the estimated time of arrival at the changed target at the next transmission time of the location information, and

the communication device transmits the at least one of the distance between the changed target and the driving assistance apparatus at the next transmission time of the location information and the estimated time of arrival at the changed target at the next transmission time of the location information, together with the map information, to the second driving assistance apparatus.

9. The driving assistance apparatus of claim 1, wherein the map information includes at least one information among setting information of the second driving assistance apparatus, road condition information, path attribute information, and diverge information.

10. The driving assistance apparatus of claim 1, further comprising a controller configured to assign a priority to the map information,

wherein the storage stores a plurality of pieces of map information to which priorities have been assigned, and

the communication device transmits the map information according to the priority.

11. The driving assistance apparatus of claim 10, wherein the controller assigns the priority to the map information according to a distance between the target of the map information and the driving assistance apparatus.

12. The driving assistance apparatus of claim 10, wherein the controller assigns the priority to the map information according to a predetermined degree of importance of the map information.

13. The driving assistance apparatus of claim 1, wherein the driving assistance apparatus includes an Audio Video Navigation (AVN) apparatus.

14. The driving assistance apparatus of claim 1, wherein the communication device transmits the map information to the second driving assistance apparatus one time if the target of the map information changes.

15. A driving assistance apparatus comprising:

a communication device configured to receive map information and location information; and

a controller configured to calculate at least one of a distance between a target of the map information and the driving assistance apparatus and an estimated time of arrival at the target of the map information, based on location information received at predetermined time periods.

16. The driving assistance apparatus of claim 15, further comprising a display configured to display at least one of the distance between the target of the map information and the driving assistance apparatus and the estimated time of arrival, calculated by the controller, for a user.

17. The driving assistance apparatus of claim 15, wherein the communication device transmits at least one of the distance between the target of the map information and the driving assistance apparatus and the estimated time of arrival at the target of the map information, calculated by the controller, to another driving assistance apparatus.

18. The driving assistance apparatus of claim 15, wherein the communication device receives a plurality of pieces of map information and a plurality of offsets corresponding to the respective pieces of map information, and

the controller calculates at least one of a distance between a target of each piece of the map information and the driving assistance apparatus and an estimated time of arrival at the target of the piece of the map information, based on the location information received at the predetermined time periods and the offsets.

19. The driving assistance apparatus of claim 15, further comprising a storage configured to store the distance between the target of the map information and the driving assistance apparatus and the estimated time of arrival at the target of the map information.

20. A control method of a driving assistance apparatus, comprising:

transmitting location information to a second driving assistance apparatus at predetermined time periods;

extracting map information; and

transmitting the map information to the second driving assistance apparatus if a target of the map information changes.

21. The control method of claim 20, further comprising, before the transmitting of the location information, receiving location information of the driving assistance apparatus.
