本文件规定了用于评估主动安全系统的系统检测和激活性能的替代目标的性能要求。 本文件规定了车辆目标的特性，使其能够在尺寸、形状、反射特性等方面代表乘用车进行测试。本文件阐述了车辆目标在本文件发布时常用的传感技术方面的检测要求，以及在可能的情况下，预期的未来传感技术。 它还介绍了验证这些传感器的目标响应特性的方法，以及目标载体的性能要求。 本文件规定了用于模拟后端场景的车辆目标的属性，重叠大于50%。本文件中的车辆目标规范旨在说明与安全关键事件相关的当前和预期测试协议，在这些事件中，目标车辆从目标车辆的后方和前方路径接近停止、制动或移动较慢（目标）的车辆。 本文件不涉及速度、位置或事件时间方面的测试程序。主动安全系统的性能标准也未提及。

This document specifies performance requirements for surrogate targets used to assess the system detection and activation performance of active safety systems. This document specifies the properties of a vehicle target that will allow it to represent a passenger vehicle in terms of size, shape, reflection properties, etc. for testing purposes. The document addresses the detection requirements for a vehicle target in terms of sensing technologies commonly in use at the time of publication of this document, and where possible, anticipated future sensing technologies. It also addresses methodologies to verify the target response properties to these sensors, as well as performance requirements for the target carrier. This document specifies the properties of the vehicle target for simulation of rear-end scenarios, with overlap greater than 50 %. The specifications of vehicle targets in this document are intended to address current and anticipated test protocols related to safety critical events in which the subject vehicle approaches a stopped, braking or slower moving (target) vehicle from behind and in the forward path of the subject vehicle. This document does not address the test procedures in terms of speeds, positions, or timing of events. Performance criteria for the active safety system are also not addressed.
