Lane-related advanced driver assistance system and control method thereof, and vehicle having the same

1 . A system comprising:

a memory for storing an image captured by a camera of a vehicle; and

a processor for controlling a lane-related Advanced Driver Assistance System (ADAS) in the vehicle using information stored in the memory,

wherein the processor is configured to:

identify a driver's intention in a rear region of a target section, which is a divergence point section without an indication line, using the image; and

determine whether to perform the lane-related ADAS function in the target section according to the identified driver's intention.

2 . The system of claim 1 , wherein the lane-related ADAS comprises a Lane Keeping System (LKS) or a Lane Departure Warning System (LDWS).

3 . The system of claim 1 , wherein the processor is configured to:

identify the driver's intention using a first change rate, which is a rate of change in a width of a driving lane in a rear region of a target section, and a second change rate, which is a rate of change in a distance of the vehicle to a lane located in an edge direction of the driving lane in the rear region of the target section, in a state where there is no operation of a turn signal lamp.

4 . The system of claim 3 , wherein the processor is configured to:

identify the first and second rates of change using the images captured at different times in the rear region.

5 . The system of claim 3 , wherein the processor is configured to:

identify that the driver's intention is a first intention to enter a connection edge lane, which is a lane connected to the driving lane, if the first and second change rates both increase.

6 . The system of claim 5 , wherein the processor is configured to:

control the lane-related ADAS function to be activated based on the connection edge lane in the target section if the first intention is identified.

7 . The system of claim 6 , wherein the processor is configured to:

control the vehicle to maintain the connection edge lane according to the activation or to generate a warning if the vehicle deviates from the connection edge lane.

8 . The system of claim 6 , wherein the processor is configured to:

control the turn signal lamp for the direction of the connection edge lane to operate upon the activation.

9 . The system of claim 3 , wherein the processor is configured to:

identify that the driver's intention is a second intention to enter a diverging lane branched from the driving lane if the first change rate increases and the second change rate decreases.

10 . The system of claim 9 , wherein the processor is configured to:

control the lane-related ADAS function to be deactivated in the target section if the second intention is identified.

11 . The system of claim 10 , wherein the processor is configured to:

control the turn signal lamp for the direction of the diverging lane to operate upon the deactivation.

12 . A control method performed in a system of a vehicle for controlling a lane-related Advanced Driver Assistance System (ADAS) using an image captured by a camera of the vehicle, the control method comprising:

identifying a driver's intention in a rear region of a target section, which is a divergence point section without an indication line, using the image; and

determining and controlling whether to perform the lane-related ADAS function in the target section according to the identified driver's intention.

13 . The control method of claim 12 , wherein the identifying comprises:

identifying the driver's intention using a first change rate, which is a rate of change in a width of a driving lane in a rear region of a target section, and a second change rate, which is a rate of change in a distance of the vehicle to a lane located in an edge direction of the driving lane in the rear region of the target section, in a state where there is no operation of a turn signal lamp.

14 . The control method of claim 13 , wherein the identifying comprises:

identifying the first and second rates of change using the images captured at different times in the rear region.

15 . The control method of claim 13 , wherein the identifying comprises:

identifying that the driver's intention is a first intention to enter a connection edge lane, which is a lane connected to the driving lane, if the first and second change rates both increase, and

identifying that the driver's intention is a second intention to enter a diverging lane branched from the driving lane if the first change rate increases and the second change rate decreases.

16 . The method of claim 15 , wherein the controlling comprises:

controlling the lane-related ADAS function to be activated based on the connection edge lane in the target section if the first intention is identified.

17 . The method of claim 16 , wherein the controlling comprises:

controlling the vehicle to maintain the connection edge lane according to the activation or to generate a warning if the vehicle deviates from the connection edge lane.

18 . The method of claim 15 , wherein the controlling comprises:

controlling the lane-related ADAS function to be deactivated in the target section if the second intention is identified.

19 . The method of claim 18 , further comprising:

controlling the turn signal lamp for the direction of the diverging lane to operate upon the deactivation.

20 . A vehicle comprising:

a camera for capturing an image of a front of the vehicle; and

a controller for performing control of a lane-related Advanced Driver Assistance System (ADAS) using the image,

wherein the controller is configured to:

identify a driver's intention in a rear region of a target section, which is a divergence point section without an indication line, using the image; and

determine whether to perform the lane-related ADAS function in the target section according to the identified driver's intention.
