本文件规定了一个开环试验程序，用于检查制动对车辆的航向保持和方向行为的影响。具体而言，该方法确定了仅通过制动作用改变车辆稳态循环响应的方式。本文件适用于ISO 3833中定义的乘用车和轻型卡车。 本试验方法中规定的开环操纵不代表实际驾驶条件，但有助于在严格控制的试验条件下获得由控制输入产生的车辆制动行为的测量值。

This document specifies an open-loop test procedure to examine the effect of braking on course holding and directional behaviour of a vehicle. Specifically, the method determines how the steady-state circular response of a vehicle is altered by a braking action only. This document is applicable to passenger cars as defined in ISO 3833 and to light trucks. The open-loop manoeuvre specified in this test method is not representative of real driving conditions but is useful to obtain measures of vehicle braking behaviour resulting from control inputs under closely controlled test conditions.
