System for forward collision avoidance through sensor angle adjustment and method thereof

1. An apparatus for forward collision avoidance, the apparatus comprising:

a position provider configured to provide information on a position of a host vehicle;

a sensor configured to sense a presence of an object in vicinity of the host vehicle; and

a vehicle controller configured to:

detect a dangerous area in a driving caution area;

increase a sensitivity of the sensor toward the dangerous area, in response to detecting the dangerous area; and

increase a forward collision avoidance performance of the host vehicle, in response to determining that the host vehicle enters the driving caution area through the position provider.

2. The apparatus of claim 1 , wherein the vehicle controller is further configured to:

sense that the host vehicle enters a low speed limit area, through the position provider.

3. The apparatus of claim 1 , wherein the vehicle controller is further configured to:

sense a parked or stopped vehicle in the driving caution area, through the sensor; and

set, as the dangerous area, an area in which a distance between parked or stopped vehicles is less than a threshold.

4. The apparatus of claim 3 , wherein the vehicle controller is further configured to:

change a sensing direction of the sensor to face the dangerous area; and

increase a sensitivity of the sensor, in response to the dangerous area being set.

5. The apparatus of claim 3 , wherein the vehicle controller is further configured to:

change braking force of the host vehicle or a time point to brake the host vehicle, in response to setting the dangerous area.

6. The apparatus of claim 1 , wherein the vehicle controller is further configured to:

provide audio-visual information or tactile information to a driver of the host vehicle, in response to sensing a moving object including a pedestrian in the dangerous area.

7. The apparatus of claim 1 , wherein the vehicle controller is further configured to:

change a sensing direction of the sensor to face the dangerous area, in response to detecting the dangerous area.

8. The apparatus of claim 7 , wherein in response to detecting the host vehicle deviating from the driving caution area, the vehicle controller is further configured to:

restore the sensing direction of the sensor to an original direction; and

restore the sensitivity of the sensor to original sensitivity.

9. A processor-implemented method for forward collision avoidance, the method comprising:

sensing that host vehicle enters a driving caution area, through a position provider providing information on a position of the host vehicle;

detecting a dangerous area in a driving caution area, through a sensor sensing a presence of an object in vicinity of the host vehicle;

increasing, by a vehicle controller, sensitivity of the sensor toward the dangerous area; and

increasing a forward collision avoidance performance of the host vehicle, in response to the detecting of the dangerous area.

10. The method of claim 9 , wherein the sensing of the host vehicle entering the driving caution area comprises:

sensing that the host vehicle enters a low speed limit area, through the position provider.

11. The method of claim 9 , wherein the detecting of the dangerous area in the driving caution area comprises:

sensing a parked or stopped vehicle in the driving caution area, through the sensor; and

setting, as the dangerous area, an area in which a distance between parked or stopped vehicles is less than a threshold.

12. The method of claim 11 , wherein the increasing of the sensitivity of the sensor, and the increasing of the forward collision avoidance performance of the host vehicle comprises:

changing a sensing direction of the sensor to face the dangerous area; and

increasing a sensitivity of the sensor, in response to the dangerous area being set.

13. The method of claim 11 , wherein the increasing of the sensitivity of the sensor, and the increasing of the forward collision avoidance performance of the host vehicle comprises:

changing braking force of the host vehicle or a time point to brake the host vehicle, in response to setting the dangerous area.

14. The method of claim 9 , further comprising:

providing audio-visual information or tactile information to a driver of the host vehicle, in response to sensing a moving object including a pedestrian in the dangerous area.

15. The method of claim 9 , wherein in response to detecting the host vehicle deviating from the driving caution area, further comprising:

restoring sensing direction of the sensor to an original direction; and

restoring the sensitivity of the sensor to original sensitivity.

16. A non-transitory computer-readable storage medium storing instructions that, when executed by a processor, cause the processor to perform the method of claim 9 .

17. An apparatus for forward collision avoidance, the apparatus comprising:

a sensor configured to sense a presence of an object in vicinity of a host vehicle; and

a vehicle controller configured to:

detect a dangerous area in a driving caution area; and

increase a sensitivity of the sensor toward the dangerous area, in response to detecting the dangerous area.

18. The apparatus of claim 17 , further comprising a position provider configured to provide position information of the host vehicle, wherein the driving caution area is determined based on the position information.

19. The apparatus of claim 17 , wherein the vehicle controller is further configured to increase a forward collision avoidance performance of the host vehicle, in response to determining that the host vehicle enters the driving caution area.
