本SAE推荐实践的目的是描述与手动控制装置的位置和标签相关的设计标准，包括嵌入式显示器和控制装置（当显示时），这是乘用车、MPV和卡车10 000 GVW以及为左舵驾驶操作而设计的。SAE人为因素研究的结果强烈影响了这些建议，特别是在驾驶员范围、控制定位性能和控制位置预期方面。只有在仔细研究了关于这些受试者的各种SAE出版物后，才应偏离本推荐实践。本文档不包括手持设备，如遥控器或手机。

The purpose of this SAE Recommended Practice is to describe design criteria pertaining to the location and labeling of hand controls, including embedded displays and controls when displayed, necessary to or frequently used during the operation of passenger cars, MPVs, and trucks 10 000 GVW and under designed for left-hand drive operation. The results of SAE human factors research have strongly influenced these recommendations, specifically in the area of driver reach, control-locating performance, and control location expectancies. Deviations from this recommended practice should be made only after careful study of the various SAE publications on these subjects. This document does not include hand-held devices such as remote controls or cellular phones.
