Abstract

Disclosed herein are a driving assistant system of a vehicle and a driving assistant method. The driving assistant system includes an image acquisition unit that acquires a front image of the vehicle, an obstacle detection unit that detects an obstacle at lateral and rear sides of the vehicle, a determination unit that determines whether a current vehicle is located at a junction road based on the acquired image, and a control unit that automatically changes a lane of the vehicle when it is determined that the current vehicle is located at the junction road and the obstacle is not detected at the lateral or rear side of the vehicle.

Claims

1. A driving assistant system of a vehicle comprising:

an image acquisition unit that acquires a front image of the vehicle;

an obstacle detection unit that detects an obstacle at lateral and rear sides of the vehicle;

a determination unit that determines whether a current vehicle is located at a junction road based on the acquired image; and

a control unit that automatically changes a lane of the vehicle when it is determined that the current vehicle is located at the junction road and the obstacle is not detected at the lateral or rear side of the vehicle.

2. The driving assistant system according to claim 1, wherein, when it is determined that the current vehicle is located at the junction road based on the acquired image and the obstacle is detected at the lateral or rear side of the vehicle, the control unit releases longitudinal and lateral automatic control including accelerating, decelerating, and lane-keeping control of the vehicle.

3. The driving assistant system according to claim 2, further comprising:

a warning unit that warns a driver when it is determined that the current vehicle is located at the junction road based on the acquired image and the obstacle is detected at the lateral or rear side of the vehicle.

4. The driving assistant system according to claim 1, wherein the determination unit determines whether the current vehicle is located at the junction road based on lane recognition information of the acquired image.

5. The driving assistant system according to claim 1, wherein the determination unit recognizes a junction road sign board based on the acquired image, and determines that the current vehicle is located at the junction road when recognizing the junction road sign board.

6. A driving assistant method of a vehicle comprising:

acquiring a front image of the vehicle;

detecting an obstacle at lateral and rear sides of the vehicle;

determining whether a current vehicle is located at a junction road based on lane recognition information of the acquired image;

performing longitudinal and lateral automatic control of the vehicle based on the front image; and

automatically changing a lane of the vehicle when it is determined that the current vehicle is located at the junction road based on the lane recognition information and the obstacle is not detected at the lateral or rear side of the vehicle.

7. The driving assistant method according to claim 6, further comprising:

releasing the longitudinal and lateral automatic control of the vehicle when it is determined that the current vehicle is located at the junction road based on the lane recognition information and the obstacle is detected at the lateral or rear side of the vehicle.

8. The driving assistant method according to claim 7, further comprising:

warning a user when it is determined that the current vehicle is located at the junction road based on the lane recognition information and the obstacle is detected at the lateral or rear side of the vehicle.

9. The driving assistant method according to claim 6, wherein the longitudinal and lateral automatic control includes accelerating, decelerating, and lane-keeping control of the vehicle.

10. A driving assistant system of a vehicle comprising:

a navigation unit that receives road information about a road on which the vehicle is traveling;

an obstacle detection unit that detects an obstacle at lateral and rear sides of the vehicle;

a determination unit that determines whether a current vehicle is located at a junction road based on the road information; and

a control unit that automatically changes a lane of the vehicle when it is determined that the current vehicle is located at the junction road and the obstacle is not detected at the lateral or rear side of the vehicle.

11. The driving assistant system according to claim 10, further comprising:

an image acquisition unit that acquires a front image of the vehicle,

wherein the determination unit re-determines whether the current vehicle is located at the junction road based on the acquired image.

12. The driving assistant system according to claim 11, wherein, when it is determined that the current vehicle is located at the junction road and the obstacle is detected at the lateral or rear side of the vehicle, the control unit releases longitudinal and lateral automatic control including accelerating, decelerating, and lane-keeping control of the vehicle or warns a driver.

13. The driving assistant system according to claim 10, wherein the determination unit determines whether the current vehicle is located at the junction road based on lane recognition information of the acquired image.

14. The driving assistant system according to claim 10, wherein the determination unit recognizes a junction road sign board based on an acquired image, and determines that the current vehicle is located at the junction road when recognizing the junction road sign board.
