Abstract

Provided are an apparatus and method for correcting sensing of a surrounding obstacle on a curved road. The apparatus includes an acquisition unit configured to acquire curvature information of a curved road on which a vehicle is traveling using a steering angle value indicating a degree of rotation of a steering wheel of the vehicle, a sensing unit configured to sense another vehicle traveling behind the vehicle, and a correction unit configured to correct sensing information of the other vehicle sensed by the sensing unit using the curvature information acquired by the acquisition unit.

Claims

1. An apparatus for correcting sensing of a surrounding obstacle on a curved road, the apparatus comprising:

an acquisition unit configured to acquire a steering angle value indicating a degree of rotation of a steering wheel of a vehicle and curvature information of a curved road on which the vehicle is traveling;

a sensing unit configured to generate sensing information of an obstacle around the vehicle; and

a correction unit configured to correct an error of the sensing information using at least one of the steering angle value and the curvature information.

2. The apparatus of claim 1, wherein the sensing unit calculates at least one of an angle value, a distance value, and a relative speed value between the vehicle and the obstacle.

3. The apparatus of claim 1, wherein the correction unit corrects the sensing information when the steering angle value is a previously set threshold value or more.

4. The apparatus of claim 2, wherein the correction unit corrects the angle value between the vehicle and the obstacle by adding or subtracting the steering angle value to/from the angle value between the vehicle and the obstacle.

5. The apparatus of claim 2, wherein the correction unit corrects at least one of the distance value and the relative speed value between the vehicle and the obstacle using the curvature information.

6. The apparatus of claim 2, wherein the correction unit corrects the distance value between the vehicle and the obstacle using the following equation employing the curvature information:

7. The apparatus of claim 2, wherein the correction unit corrects the relative speed value between the vehicle and the obstacle by multiplying the relative speed value between the vehicle and the obstacle and a ratio between the distance value between the vehicle and the obstacle and a corrected distance value between the vehicle and the obstacle.

8. A method for a sensing correction apparatus to correct sensing of a surrounding obstacle on a curved road on which a vehicle is traveling, the method comprising:

selectively acquiring at least one of a steering angle value indicating a degree of rotation of a steering wheel of the vehicle and curvature information of a curved road on which the vehicle is traveling, through a steering angle sensor of the vehicle;

generating sensing information including at least one of an angle value, a distance value, and a relative speed value between an obstacle sensed around the vehicle and the vehicle; and

correcting the sensing information using at least one of the steering angle value and the curvature information.

9. The method of claim 8, wherein the correcting of the sensing information includes correcting the sensing information when the steering angle value is a previously set threshold value or more.

10. The method of claim 8, wherein the correcting of the sensing information includes correcting the angle value between the vehicle and the obstacle by adding or subtracting the steering angle value to/from the angle value between the vehicle and the obstacle.

11. The method of claim 8, wherein the correcting of the sensing information includes correcting the distance value between the vehicle and the obstacle using the following equation employing the curvature information:

12. The method of claim 8, wherein the correcting of the sensing information includes correcting the relative speed value between the vehicle and the obstacle by multiplying the relative speed value between the vehicle and the obstacle and a ratio between the distance value between the vehicle and the obstacle and a corrected distance value between the vehicle and the obstacle.
