The invention relates to a method (1) for adjusting an automatic headlight system (8) of a motor vehicle (3). The headlight system (8) has at least two headlights for generating low beams and a control unit for adjusting a lower cut-off line (9) of the low beams. In the method, the following steps are carried out in the following order:-calculating an elevation gradient (5) from an extraction segment (4) of a digital elevation model (2) by means of mapping; determining the following two forward inflection points (6a, 6b) from the elevation gradient (5); -determining and characterizing an average road position (7) on the basis of the forward inflection points (6a, 6b); and adjusting the lower cut-off line (9) to the center point (10) of the average road position (7) at least when the first front inflection point (6a) is reached. The invention also relates to an automatic headlight system (8) of a motor vehicle (3) for implementing the method (1).
本发明涉及一种用于调节机动车辆(3)的自动前照灯系统(8)的方法(1)。所述前照灯系统(8)具有用于产生近光的至少两个前照灯和用于调节近光的下明暗截止线(9)的控制单元。在该方法中,按以下顺序执行以下步骤:‑借助于测绘根据数字高程模型(2)的提取片段(4)计算高程梯度(5);‑根据所述高程梯度(5)确定接下来的两个前方拐点(6a、6b);‑基于前方拐点(6a、6b)确定并表征平均道路位置(7);‑至少在到达第一前方拐点(6a)时,将下明暗截止线(9)调节到所述平均道路位置(7)的中心点(10)。本发明还涉及一种机动车辆(3)的自动前照灯系统(8),该系统用于实施该方法(1)。
