The SAE Recommended Practice is intended for use in measuring the radius of curvature (ROC) of spherical convex mirrors.

This SAE Recommended Practice establishes two dimensional Eyellipses representative of 90th, 95th and 99th percentile distributions of driver eye locations for use in passenger cars, trucks, buses and multipurpose passenger vehicles. New information obtained from the SAE Truck Driver Anthropometric and Workspace Study has resulted in development of new eye location procedures for trucks and other vehicles with high H-point heights and large steering wheel diameters. Therefore, this practice has been separated into two parts. Part I describes the eye location procedure for vehicles with H-point heights (H30) and steering wheel diameters (W9) less than 405mm and 450mm, respectively, which includes passenger cars, vans and light trucks (Class A Vehicles). Part I is currently under revision based on information obtained from new driver eye location studies.

This SAE Recommended Practice establishes the location of drivers’ eyes inside a vehicle for the purpose of measuring the drivers’ field of view. Elliptical (eyellipse) models in both two and three dimensions are used to represent 95th and 99th percentiles of driver eye locations. The procedure used to locate eyellipses in passenger cars differs from the procedure used for heavy trucks. Selected eye (E) points, useful in certain viewing tasks, are derived from the 95th eyellipse. For application of this Practice refer to SAE J1050 (Reference 14).

This SAE Recommended Practice establishes the location of drivers' eyes inside a vehicle. Elliptical (eyellipse) models in three dimensions are used to represent tangent cutoff percentiles of driver eye locations. Procedures are provided to construct 95th and 99th percentile tangent cutoff eyellipses for a 50/50 gender mix, adult user population. Neck pivot (P) points are defined in Section 6 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 the adjustable seat eyellipses defined in Section 4. 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), although these eyellipses have not been updated from previous versions of SAE J941. The appendices are provided for information only and are not a requirement of this document.
