本文件规定了一种方法，用于评估配备自动紧急制动系统（AEBS）或动态制动支持（DBS）的车辆在几种事故场景中的行为。当被测车辆（VUT）接近同一车道上的另一车辆时，这些事故发生在直线行驶期间。两辆车在纵轴上相互对齐。 在这些事故场景中，车辆行为的最重要部分是避免或减轻碰撞的能力。 需要驾驶员干预的系统不在本文件的范围内。 注意了吗根据事故学，只有部分场景可用于性能评估。基于本文件的AEB系统评估仅限于纵向事故场景。

This document specifies a method to evaluate the behaviour of a vehicle equipped with an autonomous emergency braking system (AEBS), or dynamic brake support (DBS) during several accident scenarios. Those accidents occur during a straight-line driving when the vehicle under test (VUT) approaches another vehicle in the same lane. Both vehicles are aligned in longitudinal axis to each other. The most important part of the vehicle behaviour during these accidents scenarios is the capacity to avoid or mitigate the collision. Systems requiring driver intervention are not in the scope of this document. NOTE？Depending on accidentology, only a part of the scenarios can be used for an evaluation of performance. AEB system evaluation based upon this document is limited to longitudinal accident scenarios.
