The invention relates to the technical field of vehicle headlamp control, in particular to a vehicle headlamp adjusting method. The method comprises the following steps: S1, calculating a preset angle alpha between a main light beam of a headlamp and the vertical direction of the ground: alpha = arctan (S/H); wherein S is the sum of the braking distance of the vehicle and the response distance of the driver; h is the height of the headlamp. S2, confirming an actual angle beta between a main light beam of the headlamp and the vertical direction of the ground; and S3, the angle between the main light beam of the headlamp and the vertical direction of the ground is adjusted, and the adjustment amount is alpha-beta. The irradiation distance of the main light beam of the headlamp is adjusted according to the running speed of the vehicle, the view field of an opposite coming vehicle and a coming person cannot be affected by too far irradiation, and the view field of the vehicle cannot be affected by too close irradiation.

    本发明涉及车辆大灯控制技术领域,具体的,涉及一种车辆大灯调节方法。该方法包括以下步骤:S1、计算大灯主光束与地面垂直方向之间的预定角度α:α=arctan(S/H);其中:S为车辆的刹车距离+驾驶员反应距离;H为大灯的高度。S2、确认大灯主光束与地面垂直方向之间的实际角度β;S3、调节大灯主光束与地面垂直方向之间的角度,调整量为:α‑β。实现根据车辆行驶速度调节大灯主光束照射距离,既不会因照射过远影响对向来车、来人视野,也不会因照射过近影响本车的视野。
