Abstract

A vehicle includes an input unit configured to receive an input of a control point and a control degree related to lane keeping; a lane controller configured to determine whether to perform a lane keeping control based on the input control point, road conditions and a vehicle condition in the road; and a controller configured to control the vehicle'"'"'s driving based on the control degree when the lane controller determines to perform the lane keeping control.

Claims

1. A vehicle comprising:

an input unit configured to receive an input of a control point and a control degree related to lane keeping;

a lane controller configured to determine whether to perform a lane keeping control based on the input control point, road conditions and vehicle conditions in the road; and

a controller configured to control the vehicle'"'"'s driving based on the control degree when the lane controller determines to perform the lane keeping control,

wherein the lane controller derives road condition information used to recognize the road conditions and vehicle condition information used to recognize the vehicle conditions.

2. The vehicle of claim 1, wherein

the input unit receives an input of a control point for a left lane and a control degree for a left lane, and a control point for a left lane and a control degree for a right lane, individually.

3. The vehicle of claim 1, wherein

the input unit receives an input of a lane keeping level, which relates the control point and the control degree.

4. The vehicle of claim 1, wherein

the controller displays a user interface configured to receive an input of at least one of the control point, the control degree, and a lane keeping level of the vehicle in a display unit.

5. The vehicle of claim 1, wherein

the controller displays a user interface configured to receive input of at least one of the control point, the control degree, and a lane keeping level, where the lane keeping level is within a pre-set range.

6. The vehicle of claim 1, further comprising:

a recording unit configured to acquire image information related to a front area of the vehicle.

7. The vehicle of claim 6, wherein

the lane controller derives the road condition information and the vehicle condition information from the image information acquired by the recording unit by image processing.

8. The vehicle of claim 7, wherein

the lane controller determines whether to perform the lane keeping control based on the road condition information, the vehicle condition information, and the input control point.

9. The vehicle of claim 1, wherein

the lane controller determines a steering torque value to be applied to a steering wheel based on the input control degree.

10. The vehicle of claim 9, wherein

the lane controller applies a torque to the steering wheel based on the steering torque value.

11. The vehicle of claim 2, wherein

the lane controller independently determines whether to perform the lane keeping control for the left lane and the right lane based on the input control points for the left lane and the right lane, respectively, and independently determines steering torques for the left lane and the right lane based on the input control degrees for the left lane and the right lane, respectively.

12. A control method of a vehicle comprising steps of:

receiving an input of a control point and a control degree related to lane keeping;

determining whether to perform a lane keeping control based on the input control point, road conditions and vehicle conditions in the road; and

controlling the vehicle'"'"'s driving based on the control degree when the lane keeping control is determined to be performed,

wherein the determining further comprises deriving road condition information used to recognize road the conditions and vehicle condition information used to recognize the vehicle conditions.

13. The control method of claim 12 wherein

the step of receiving an input includes receiving an input of a control point for a left lane, a control degree for a left lane, a control point for a right lane and a control degree for a right lane, individually.

14. The control method of claim 12 wherein

the step of receiving an input includes receiving a lane keeping level which relates the control point and the control degree.

15. The control method of claim 12 wherein

the step of receiving an input comprises acquiring image information related to a front area of the vehicle.

16. The control method of claim 15 wherein

the step of determining further comprises deriving the road condition information and the vehicle condition information from the acquired image information by image processing.

17. The control method of claim 16 wherein

the step of determining further comprises determining whether to perform the lane keeping control based on the road condition information, the vehicle condition information, and the input control point.

18. The control method of claim 12 wherein

the step of determining includes determining a steering torque value applied to a steering wheel based on the input control degree.

19. The control method of claim 12 wherein

the step of controlling includes applying a torque to the steering wheel based on the steering torque value.

20. The control method of claim 13 wherein

the step of determining further comprises determining whether to perform the lane keeping control for the left lane and the right lane based on the control points of the left lane and the right lane, respectively, and determining steering torques for the left lane and the right lane based on the input control degrees of the left lane and the right lane, respectively.
