摘　　要：针对标准GB 18447-2008中前照灯近光照射在距离10 m远屏幕上的明暗截止线水平部分(或转折点)离地高度的规定,分析前照灯远、近光照射高度与拖拉机最小制动减速度时的最长制动距离的关系,得出前照灯远、近光照射在距离10 m远屏幕上离地高度的范围,并使远、近光照射落地距离满足驾驶员在夜间正常行驶车速下发现障碍物后所采取的减速措施安全有效。Aiming at the regulation about ground clearance of the cut-off line horizontal section in GB 18447-2007 when lower beam of headlamp irradiated on a 10 meter far screen,the paper analyzed the relationship between irradiation height of headlamp’s far and lower beam and minimum braking distance at minimum braking deceleration,obtained the range of ground clearance when headlamp’s far and lower beams irradiated on a 10 meter far screen,and which could ensure that the deceleration measure adopted by driver is effective when driver found the barrier under normal condition at night.
