Abstract

Disclosed are a system and a method for complementing a position of a vehicle and an apparatus for controlling complementing a position of a vehicle that select a representative vehicle within divided areas and complement a position of an own vehicle from a representative vehicle by using a DGPS complementation signal received through vehicle to vehicle (V2V) communication and vehicle to infrastructure (V2I) communication.

Claims

1. An apparatus for controlling complementing a position of a vehicle, comprising:

an area dividing unit configured to divide a large area into small areas according to a predetermined criterion;

a representative vehicle deciding unit configured to decide a representative vehicle among vehicles positioned in each small area; and

a data transmission controlling unit configured to, within a same small area as the representative vehicle and remaining vehicles therewithin, first control a DGPS complementation value to be transmitted to the representative vehicle and thereafter, control the DGPS complementation value to be transmitted to the remaining vehicles.

2. The apparatus of claim 1, wherein the area dividing unit uses a communicatable distance between two vehicles or coverage of a base station as the criterion.

3. The apparatus of claim 2, wherein the area dividing unit uses the representative vehicle as one of the two vehicles at the time of using the communicatable distance between two vehicles as the criterion.

4. The apparatus of claim 1, wherein the representative vehicle deciding unit first decides the representative vehicle and a candidate vehicle and again decides the representative vehicle or the candidate vehicle depending on whether the representative vehicle or the candidate vehicle deviates from the small area.

5. The apparatus of claim 4, wherein the representative vehicle deciding unit changes the candidate vehicle to the representative vehicle and decides a vehicle that has entered the small area most recently as the candidate vehicle when the representative vehicle deviates from the small area and decides the vehicle that has entered the small area most recently as the candidate vehicle when the candidate vehicle deviates from the small area.

6. A system for complementing a position of a vehicle, comprising:

a vehicle position complementation controlling apparatus configured to include an area dividing unit configured to divide a large area into small areas according to a predetermined criterion, a representative vehicle deciding unit configured to decide a first representative vehicle among vehicles positioned in each small area, and a data transmission controlling unit configured to, within a same small area as the representative vehicle and remaining vehicles therewithin, first control a DGPS complementation value to be transmitted to the first representative vehicle and thereafter, control the DGPS complementation value to be transmitted to the remaining vehicles;

a first representative vehicle configured to receive the DGPS complementation value from a second representative vehicle positioned at a base station or another small area and complement a position thereof based on the DGPS complementation value; and

the remaining vehicles configured to complement positions thereof based on the DGPS complementation value received from the first representative vehicle.

7. The system of claim 6, wherein the first representative vehicle receives the DGPS complementation value and information on a time when the DGPS complementation value is generated, selects a DGPS complementation value which is generated most recently based on a time information when at least two DGPS complementation values are received, and complements a position thereof based on the selected DGPS complementation value.

8. The system of claim 6, wherein the remaining vehicles receive identification information together with the DGPS complementation value, determine whether the DGPS complementation value is received from a representative vehicle in a small area to which each of the remaining vehicles belongs by using the identification information, and complement positions thereof based on the DGPS complementation value when it is determined that the DGPS complementation value is received from the representative vehicle in the small area to which each of the remaining vehicles belongs.

9. The system of claim 8, wherein the identification information includes latitude and longitude information.

10. The system of claim 8, wherein the remaining vehicles receive the DGPS complementation value and information on a time when the DGPS complementation value is generated, select a DGPS complementation value which is generated most recently based on a time information when at least two DGPS complementation values are received from the representative vehicle in the small area to which each of the remaining vehicles belongs, and complement positions thereof based on the selected DGPS complementation value.

11. The system of claim 6, wherein the DGPS complementation value is generated by the base station.

12. A method for complementing a position of a vehicle, comprising:

dividing, by a vehicle position complementation controlling apparatus, a large area into small areas according to a predetermined criterion;

deciding, by the vehicle position complementation controlling apparatus, a first representative vehicle among vehicles positioned in each small area;

receiving, by the first representative vehicle, the DGPS complementation value from a second representative vehicle positioned at a base station or another small area and complementing a position thereof based on the DGPS complementation value; and

complementing, by the remaining vehicles positioned in the same small area as the first representative vehicle, positions thereof based on the DGPS complementation value received from the first representative vehicle while the first representative vehicle remains within the same small area.

13. The method of claim 12, wherein in the dividing, by the vehicle position complementation controlling apparatus, a large area into small areas according to a predetermined criterion,

a communicatable distance between two vehicles or coverage of a base station is used as the criterion.

14. The method of claim 13, wherein in the dividing, by the vehicle position complementation controlling apparatus, a large area into small areas according to a predetermined criterion,

the representative vehicle is used as one of the two vehicles at the time of using the communicatable distance between two vehicles as the criterion.

15. The method of claim 12, wherein in the deciding, by the vehicle position complementation controlling apparatus, a first representative vehicle among vehicles positioned in each small area,

the representative vehicle and a candidate vehicle are first decided and the representative vehicle or the candidate vehicle is decided again depending on whether the representative vehicle or the candidate vehicle deviates from the small area.

16. The method of claim 15, wherein in the deciding, by the vehicle position complementation controlling apparatus, a first representative vehicle among vehicles positioned in each small area,

the candidate vehicle is changed to the representative vehicle and a vehicle that has entered the small area most recently is decided as the candidate vehicle when the representative vehicle deviates from the small area and the vehicle that has entered the small area most recently is determined as the candidate vehicle when the candidate vehicle deviates from the small area.

17. The method of claim 12, wherein in the receiving, by the first representative vehicle, the DGPS complementation value from a second representative vehicle positioned in a base station or another small area and complementing a position thereof based on the DGPS complementation value,

the DGPS complementation value and information on a time when the DGPS complementation value is generated are received, a DGPS complementation value which is generated most recently is selected based on a time information when at least two DGPS complementation values are received, and a position thereof is complemented based on the selected DGPS complementation value.

18. The method of claim 12, wherein in the complementing, by the remaining vehicles positioned in the same small area as the first representative vehicle, positions thereof based on the DGPS complementation value received from the first representative vehicle,

identification information is received together with the DGPS complementation value, it is determined whether the DGPS complementation value is received from a representative vehicle in a small area to which each of the remaining vehicles belongs by using the identification information, and positions thereof are complemented based on the DGPS complementation value when it is determined that the DGPS complementation value is received from the representative vehicle in the small area to which each of the remaining vehicles belongs.

19. The method of claim 18, wherein in the complementing, by the remaining vehicles positioned in the same small area as the first representative vehicle, positions thereof based on the DGPS complementation value received from the first representative vehicle,

the DGPS complementation value and information on a time when the DGPS complementation value is generated are received, a DGPS complementation value which is generated most recently is selected based on a time information when at least two DGPS complementation values are received from the representative vehicle in the small area to which each of the remaining vehicles belongs, and positions thereof are complemented based on the selected DGPS complementation value.
