智能交通系统.自行车检测和碰撞缓解系统（BDCMS）.性能要求和试验程序

[中文适用范围]： 本文件规定了骑车人检测和碰撞缓解系统 (BDCMS) 的操作概念、最低功能、系统要求、系统接口和测试程序。 它还定义了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。 BDCMS 的根本目的是为配备的车辆提供紧急制动 (EB)，以减轻主体车辆 (SV) 和骑自行车者之间的碰撞严重程度。 BDCMS 检测 SV 前方的骑车人，确定检测到的骑车人相对于 SV 是否处于危险情况，如果存在危险情况且碰撞即将发生，则启动 EB。 包含其他对策（例如规避转向）的系统不属于本文档的范围。 本文件定义了两种类型的 BDCMS（基于不同环境照度下的操作）和两类 BDCMS（基于不同车辆尺寸类别的操作），如表 1 所示。 本文件不适用于摩托车。 运营设计范围为公共道路。 BDCMS 不适合越野使用。 表 1 — BDCMS 的类型和类别 BDCMS I 类 BDCMS II 类 BDCMS I 类 仅白天 仅限轻型车辆 仅白天 仅限重型车辆 BDCMS II 型 白天、黄昏和夜间 仅限轻型车辆 白天、黄昏和夜间 重型仅限车辆 车辆安全运行的责任由驾驶员承担。 打算在公共道路上使用的可取得许可的机动车辆（即摩托车、汽车、轻型卡车、公共汽车、大客车）和其他具有危险性的重型车辆不在本文件的范围内，并包含在 ISO 22839 的范围内。 行人不在危险范围内。 本文件包含在 ISO 19237 范围内。 附件 A 包含与 BDCMS 相关的信息。 [外文原描述]： This document specifies the concept of operation, minimum functionality, system requirements, system interfaces, and test procedures for bicyclist detection and collision mitigation systems (BDCMS). It also defines 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. BDCMS are fundamentally intended to provide emergency braking (EB) of equipped vehicles in order to mitigate collision severity between the subject vehicle (SV) and a bicyclist. BDCMS detect bicyclists forward of the SV, determine if the detected bicyclists are in a hazardous situation with respect to the SV, and initiate EB if a hazardous situation exists and a collision is imminent. Systems that include other countermeasures such as evasive steering are outside the scope of this document. This document defines two types of BDCMS (based on operation in different ambient illuminance) and two classes of BDCMS (based on operation on different vehicle size classes), as depicted in Table 1. This document does not apply to motorcycles. The operational design domain is public roads. BDCMS is not intended for off-road use. Responsibility for the safe operation of the vehicle remains with the driver. Licensable motor vehicles intended for use on public roads (i.e. motorcycles, cars, light trucks, buses, motor coaches), and other heavy vehicles as hazards are outside the scope of this document and are covered under ISO 22839. Pedestrians are outside the scope of this document and are covered under ISO 19237. Annex A contains informative information relative to BDCMS.
