2、 2、FCW Forward Collision Warning ISO 15623 Introduction 介绍 The main system function of FVCW is to warn the driver when the subject vehicle encounters the situation of a forward vehicle in the subject vehicles trajectory become a potential hazard. This is done by using information such as: FVCW的主要功能
3、是当目标车辆在目标车辆轨迹中遇到前方车辆的情况时警告驾驶员 成为潜在危险。 这是通过使用信息如: (1) The range to forward vehicles (2) The relative velocity of the forward vehicles with respect to subject vehicle (3) Whether a forward vehicle in the subject vehicle trajectory. Based upon the information acquired, the controller identified as “FVC
4、WS target selection and warning strategy” in produces the waring to the driver. 根据所获得的信息，控制器被识别为“FVCWS目标选择和警告策略”，警告驾驶员。 Automobile manufacturers and component suppliers throughout the world have been vigorously pursuing the development and commercialisation of the FVCWS systems. Systems of this type
5、 have already been introduced on to the market in some countries. Thus the standardization efforts began in 1994 amongst interested countries. This International Standard is composed to address only the basic performance requirements and test procedures for the FVCWS type systems which have more fea
6、tures and may extend beyond this International Standard. 世界各地的汽车制造商和零部件供应商一直在大力推进FVCWS系统的 开发和商业化。 这种类型的系统已经在一些国家推向市场。 因此，有 关国家于1994年开始了标准化工作。本国际标准的组成仅针对FVCWS 型系统的基本性能要求和测试程序，这些系统具有更多特性，可能超出 本国际标准。 彭小权 2、FCW Forward Collision Warning 3、ISO 15623 Terms and definitions术语和定义 SN.TermsDefinitions 3.1Coll

12、vehicle only, that is cars, trucks, buses, and motorcycles 无论是移动的还是静止的车辆，可以通过该系统检测到的潜在危险，都考虑到。 例如汽车，卡车，公共汽车和摩托车 3.6Preliminary collision warning Information that the system gives to the driver in the early stages of a potentially dangerous situation that may result in a rear end collision Note 1 to
13、entry: The systems may provide this warning prior to the collision warning . 系统在可能导致尾部碰撞的潜在危险情况的早期阶段给予驾驶员的信息 注1：系统可能会在碰撞警告之前提供此警告。 彭小权 2、FCW Forward Collision Warning 3、ISO 15623 Terms and definitions术语和定义 SN.TermsDefinitions 3.7Radar cross section RCS Measure of the reflective strength of a radar
