智能交通系统 - 行人检测和碰撞缓解系统（PDCMS） - 性能要求和测试程序

[中文适用范围]： 本文件规定了行人检测和碰撞缓解系统 (PDCMS) 的操作概念、最低功能、系统要求、系统接口和测试程序。 它指定了 PDCMS 所需的行为，以及验证给定实现是否满足本文档要求所需的系统测试标准。 只要有可能，实现选择就留给系统设计者。 PDCMS 可降低无法避免的行人碰撞的严重程度，并可降低死亡和严重受伤的可能性。 PDCMS 需要有关行人范围、行人运动、目标车辆 (SV) 运动、驾驶员命令和驾驶员操作的信息。 PDCMS 提前检测行人，确定检测到的行人是否代表危险状况，并在存在危险时警告驾驶员。 PDCMS 估计驾驶员是否有足够的机会应对危险。 如果驾驶员没有足够的时间做出反应，并且满足适当的标准，则 PDCMS 会确定碰撞即将发生。 根据此评估，PDCMS 将激活 CW 和车辆制动器，以减轻碰撞严重程度。 该文件虽然不是防撞标准，但并不妨碍制造商使用 PDCMS 实施防撞。 包含其他对策（例如规避转向）的系统不在本文档的范围内。 车辆安全运行的责任仍由驾驶员承担。 本文件适用于轻型客车（见3.6）。 它不适用于其他车辆类别，例如重型车辆或摩托车。 PDCMS 不适合越野使用。 [外文原描述]： ISO 19237:2017 specifies the concept of operation, minimum functionality, system requirements, system interfaces, and test procedures for Pedestrian Detection and Collision Mitigation Systems (PDCMS). It specifies the behaviours that are required for PDCMS, and the system test criteria necessary to verify that a given implementation meets the requirements of this document. Implementation choices are left to system designers wherever possible. PDCMS reduce the severity of pedestrian collisions that cannot be avoided, and may reduce the likelihood of fatality and severity of injury. PDCMS require information about range to pedestrians, motion of pedestrians, motion of the subject vehicle (SV), driver commands and driver actions. PDCMS detect pedestrians ahead of time, determine if detected pedestrians represent a hazardous condition, and warn the driver if a hazard exists. PDCMS estimate if the driver has an adequate opportunity to respond to the hazard. If there is inadequate time available for the driver to respond, and if appropriate criteria are met, PDCMS determine that a collision is imminent. Based upon this assessment, PDCMS will activate CWs and vehicle brakes to mitigate collision severity. This document, while not a collision avoidance standard, does not preclude a manufacturer from implementing collision avoidance with PDCMS. Systems that include other countermeasures such as evasive steering are not within the scope of this document. Responsibility for the safe operation of the vehicle remains with the driver. ISO 19237:2017 applies to light duty passenger vehicles (see 3.6). It does not apply to other vehicle categories such as heavy vehicles or motorcycles. PDCMS are not intended for off-road use.
