道路车辆.能见度.驾驶员眼睛位置用眼线的建立方法

[中文适用范围]： 该文件确定了驾驶员眼睛在车内的位置。 三维椭圆（眼椭圆）模型用于表示驾驶员眼睛位置的切线截止百分位数。 提供了为 50/50 性别混合的成人用户群体构建第 95 个和第 99 个百分位切线截止眼椭圆的程序。 颈部枢轴 (P) 点的定义是为 SAE J1050 中描述的直接和间接观察任务建立特定的左眼和右眼点。 这些 P 点仅针对可调节座椅椭圆形进行定义。 本文件适用于 SAE J1100 中定义的 A 类车辆（乘用车、多用途乘用车和轻型卡车）。 它也适用于 B 类车辆（重型卡车）。 [外文原描述]： This document establishes the location of drivers' eyes inside a vehicle. Elliptical (eyellipse) models in three dimensions are used to represent tangent cut-off percentiles of driver's eye locations. Procedures are provided to construct 95th and 99th percentile tangent cut-off eyellipses for a 50/50 gender mix, adult user population. Neck pivot (P) points are defined to establish specific left and right eye points for direct and indirect viewing tasks described in SAE J1050. These P points are defined only for adjustable seat eyellipses. This document applies to Class A vehicles (passenger cars, multipurpose passenger vehicles and light trucks) as defined in SAE J1100. It also applies to Class B vehicles (heavy trucks).
