Abstract

An apparatus and a method for detecting a traffic lane using wireless communication is provided and includes a sensor unit including an image recognition sensor and a radar sensor. In addition, a controller is configured to wirelessly communicate with at least one of a plurality of other vehicles and generate road driving information regarding a traveling vehicle after confirming a reliability of the at least one other vehicle using traffic lane recognition information received from the at least other vehicle. The controller is configured to confirm a traffic lane of the traveling vehicle based on the reliability and output the road driving information.

Claims

1. An apparatus for recognizing a traffic lane using wireless communication, the apparatus comprising:

a sensor unit including an image recognition sensor and a radar sensor; and

a controller configured to;

communicate wirelessly with at least one of a plurality of other vehicles;

generate road driving information of a traveling vehicle after confirming a reliability of the plurality of other vehicles using traffic lane recognition information received from the at least one other vehicle;

confirm a traffic lane of the traveling vehicle according to the reliability; and

output the road driving information.

2. The apparatus of claim 1, wherein the controller is further configured to:

confirm the traffic lane of the traveling vehicle when the traffic lane of the traveling vehicle is recognized as the same traffic lane equal to or greater than a threshold.

3. The apparatus of claim 2, wherein the threshold is determined based on the reliability of the at least one other vehicle.

4. The apparatus of claim 3, wherein the controller is further configured to:

confirm the reliability based on the sensor unit including the image recognition sensor and the radar sensor of the at least one other vehicle, coordinate values for a position of the at least one other vehicle, a distance between the at least one other vehicle and the traveling vehicle, and the traffic lane recognition information that includes a position of the traffic lane for the at least other vehicle.

5. The apparatus of claim 4, wherein the controller is further configured to:

confirm the coordinate values for the position of the at least one other vehicle using a global positioning system (GPS).

6. The apparatus of claim 4, wherein the controller is further configured to:

confirm the at least one other vehicle as a vehicle having a reliability of 1 when the at least other vehicle includes the image recognition sensor and is positioned in an end lane.

7. The apparatus of claim 4, wherein the controller is further configured to:

confirm the at least one other vehicle as a vehicle having a reliability of 3 when the at least one other vehicle includes a plurality of sensors and a distance between the at least one other vehicle and the traveling vehicle is within a threshold distance.

8. A method for detecting a traffic lane using wireless communication, the method comprising:

entering, by a controller, into a traffic lane recognition mode based on a user input;

receiving, by the controller, traffic lane recognition information from at least one of a plurality of other vehicles via a wireless communication;

confirming, by the controller, a reliability of the at least one other vehicle from the traffic lane recognition information;

confirming, by the controller, a traffic lane of a traveling vehicle based on the reliability; and

generating and outputting, by the controller, road driving information including the confirmed traffic lane.

9. The method of claim 8, wherein confirming a reliability includes:

confirming, by the controller, the reliability based on a sensor unit including an image recognition sensor and a radar sensor of the at least one other vehicle, coordinate values for a position of the at least one other vehicle, a distance between the at least one other vehicle and the traveling vehicle, and the traffic lane recognition information that includes a position of the traffic lane for the at least one other vehicle.

10. The method of claim 9, wherein confirming a reliability includes:

confirming, by the controller, the at least other vehicle as a vehicle having a reliability of 1 when the at least other vehicle includes the image recognition sensor and is positioned in an end lane;

confirming, by the controller, the at least one other vehicle as a vehicle having a reliability of 3 when the other vehicle includes a plurality of sensors and a distance between the at least one other vehicle and the traveling vehicle is within a threshold distance.

11. The method of claim 10, wherein confirming a traffic lane includes:

calculating, by the controller, the distance between the at least one other vehicle and the traveling vehicle;

estimating, by the controller, the traffic lane of the traveling vehicle using the calculated distance; and

confirming, by the controller, the traffic lane of the traveling vehicle when the traffic lane of the traveling vehicle is predicted as the same traffic lane equal to or greater than a threshold.

12. A non-transitory computer readable medium containing program instructions executed by a controller, the computer readable medium comprising:

program instructions that enter into a traffic lane recognition mode based on a user input;

program instructions that receive traffic lane recognition information from at least one of a plurality of other vehicles via a wireless communication;

program instructions that confirm a reliability of the at least one other vehicle from the traffic lane recognition information;

program instructions that confirm a traffic lane of a traveling vehicle based on the reliability; and

program instructions that generate and output road driving information including the confirmed traffic lane.

13. The non-transitory computer readable medium of claim 12, further comprising:

program instructions that confirm the reliability based on a sensor unit including an image recognition sensor and a radar sensor of the at least one other vehicle, coordinate values for a position of the at least one other vehicle, a distance between the at least one other vehicle and the traveling vehicle, and the traffic lane recognition information that includes a position of the traffic lane for the at least one other vehicle.

14. The non-transitory computer readable medium of claim 13, further comprising:

program instructions that confirm the at least other vehicle as a vehicle having a reliability of 1 when the at least other vehicle includes the image recognition sensor and is positioned in an end lane;

program instructions that confirm the at least one other vehicle as a vehicle having a reliability of 3 when the other vehicle includes a plurality of sensors and a distance between the at least one other vehicle and the traveling vehicle is within a threshold distance.

15. The non-transitory computer readable medium of claim 14, further comprising:

program instructions that calculate the distance between the at least one other vehicle and the traveling vehicle;

program instructions that estimate the traffic lane of the traveling vehicle using the calculated distance; and

program instructions that confirm the traffic lane of the traveling vehicle when the traffic lane of the traveling vehicle is predicted as the same traffic lane equal to or greater than a threshold.
