Abstract

A driver assistance apparatus includes a camera configured to acquire an around-view image of a view around a vehicle; an output unit; and at least one processor. The at least one processor is configured to: based on the around-view image, detect a current driving lane and determine a type of a line that delineates the current driving lane; acquire information regarding an object located in an adjacent lane next to the current driving lane; and based on the type of the line that delineates the current driving lane and based on the information regarding the object, determine whether to output a warning via the output unit.

Claims

1. A driver assistance apparatus comprising:

a camera configured to acquire an around-view image of a view around a vehicle;

an output unit; and

at least one processor configured to;

based on the around-view image, detect a current driving lane and determine a type of a line that delineates the current driving lane;

acquire information regarding an object located in an adjacent lane next to the current driving lane; and

based on the type of the line that delineates the current driving lane and based on the information regarding the object, determine whether to output a warning via the output unit.

2. The driver assistance apparatus according to claim 1, wherein the at least one processor is further configured to, based on the object being a nearby vehicle:

acquire route information of the nearby vehicle; and

determine, further based on the route information, whether to output the warning via the output unit.

3. The driver assistance apparatus according to claim 1, wherein the at least one processor is configured to:

determine whether the line that delineates the current driving lane is permitted to be crossed; and

determine, further based on a result of the determination, whether to output the warning via the output unit.

4. The driver assistance apparatus according to claim of claim 3, wherein the at least one processor is configured to:

based on a determination that the line that delineates the current driving lane is not permitted to be crossed, control the output unit to not output the warning in response to detection of the object in the adjacent lane next to the line that is not permitted to be crossed.

5. The driver assistance apparatus according to claim 4, wherein the at least one processor is configured to:

based on the current driving lane being delineated by a center line, control the output unit to not output the warning in response to detection of a nearby vehicle travelling in the adjacent lane on an opposite side of the center line from the current driving lane.

6. The driver assistance apparatus according to claim 4, wherein the at least one processor is configured to:

detect a guardrail based on the around-view image; and

control the output unit to not output the warning in response to detection of a nearby vehicle travelling in the adjacent lane on an opposite side of the guardrail from the current driving lane.

7. The driver assistance apparatus according to claim 4, wherein the at least one processor is configured to:

based on the current driving lane being delineated by a solid lane, control the output unit to not output the warning in response to detection of a nearby vehicle travelling in the adjacent lane next to the current driving lane with the solid line therebetween.

8. The driver assistance apparatus according to claim 4, wherein the at least one processor is configured to:

based on the current driving lane being next to a sidewalk, control the output unit to not output the warning in response to detection of the object located on the sidewalk.

9. The driver assistance apparatus according to claim 1, further comprising an interface configured to receive navigation information,

wherein the at least one processor is configured to determine, further based on the navigation information, whether to output the warning via the output unit.

10. The driver assistance apparatus according to claim 9, wherein the at least one processor is configured to:

match information regarding the current driving lane with the navigation information; and

determine, based on a result of the matching, whether to output the warning via the output unit.

11. The driver assistance apparatus according to claim 9,

wherein the navigation information comprises route information of a vehicle, and

wherein the at least one processor is configured to, based on turn signal input information corresponding to the route information being received, control the output unit to not output the warning in response to detection of an object in the adjacent lane that is next to the current driving lane in a direction of a turn signal.

12. The driver assistance apparatus according to claim 11, wherein the at least one processor is configured to:

based on the current driving lane being a left turn lane, and based on turn signal input information for making a left turn in the current driving lane being received, control the output unit to not output the warning in response to detection of the object in the adjacent lane that is on a left side of the current driving lane.

13. The driver assistance apparatus according to claim 11, wherein the at least one processor is configured to:

based on the current driving lane being a right turn lane, and based on turn signal input information for making a right turn in the current driving lane being received, control the output unit to not output the warning in response to detection of the object in the adjacent lane that is on a right side of the current driving lane.

14. The driver assistance apparatus according to claim 1, wherein the at least one processor is configured to:

acquire information regarding a curve in the current driving lane based on the vehicle around-view image; and

determine, further based on the information regarding the curve, whether to output the warning via the output unit.

15. The driver assistance apparatus according to claim 14, wherein the at least one processor is configured to:

based on the vehicle travelling around the curve, determine, based on the vehicle around-view image, whether a detected nearby vehicle is travelling in the current driving lane; and

based on a determination that the nearby vehicle is travelling in the current driving lane, control the output unit to not output the warning.

16. The driver assistance apparatus according to claim 15, wherein the at least one processor is configured to:

acquire curvature information of the curve; and

control a change of a preset blind spot area that is detected based on the curvature information.

17. The driver assistance apparatus according to claim 1, wherein the at least one processor is configured to:

acquire driving situation information of the vehicle; and

control a change of a preset blind spot area that is detected based on the driving situation information.

18. The driver assistance apparatus according to claim 17, wherein the at least one processor is configured to:

acquire pulling-out situation information regarding moving the vehicle out of a stopped state; and

change a position of the preset blind spot area that is detected toward a direction of travel of the vehicle based on the information regarding moving the vehicle out of the stopped state.

19. The driver assistance apparatus according to claim 17, wherein the at least one processor is configured to:

acquire at least one of left-turn situation information, right-turn situation information, or U-turn situation information; and

change a position of the preset blind spot area that is detected toward a direction of travel of the vehicle based on the at least one of the left-turn situation information, the right-turn situation information, or the U-turn situation information.

20. The driver assistance apparatus according to claim 1, wherein the at least one processor is configured to:
