The method includes: determining a safe sight distance corresponding to a current position of a vehicle according to a current speed of vehicle; calculating, in combination with the electronic horizon data ahead, a difference of view inclination of each gradient point relative to the current position of the vehicle within the safe sight distance; screening the gradient points sequentially from the farthest gradient point within the safe sight distance until the differences of view inclination corresponding to all the gradient points between the screened gradient point and the current position of the vehicle are within a lighting angle range corresponding to the screened gradient point; and adjusting the illumination angle using the difference of view inclination corresponding to the screened gradient point as the vertical adjustment angle of the adaptive front-lighting system.
