Abstract
Provided is technology for increasing stability/reliability of an adaptive front lighting system (AFLS) and driving convenience by adjusting a front light irradiation angle of a host vehicle based on analysis of a difference between an inclination angle of a road where the host vehicle is driving and an inclination angle of a road where an opposing vehicle is driving as the inclination angle of the road is changed.
Claims9
A front light irradiation angle adjustment system comprising:
- an image input unit receiving front image data of a host vehicle;
- an image analysis unit analyzing the front image data to estimate a pitch rotation angle of an opposing vehicle included in the front image data;
- and
- a control generation unit generating a control signal for adjusting an irradiation angle of front lights of the host vehicle by comparing a set front light irradiation angle of the host vehicle with the estimated pitch rotation angle of the opposing vehicle.
A front light irradiation angle adjustment method using a front light irradiation angle adjustment system in which each operation is performed by an electronic control unit the method comprising:
- inputting an image of front image data of a host vehicle;
- analyzing the front image data to estimate a pitch rotation angle of an opposing vehicle included in the front image data;
- comparing a set front light irradiation angle of the host vehicle with the estimated pitch rotation angle of the opposing vehicle;
- generating a control signal for adjusting the front light irradiation angle of the host vehicle based on a value acquired by subtracting the pitch rotation angle of the opposing vehicle from the front light irradiation angle of the host vehicle when the pitch rotation angle of the opposing vehicle is larger;
- and
- adjusting the front light irradiation angle of the host vehicle by transmitting the control signal to a front light irradiation angle control.
