重型商用车和公共汽车. 规定路径上的紧急制动. 轨迹测量试验方法

[中文适用范围]： 该文件描述了用于确定在由紧急制动系统引起的制动操纵期间车辆行驶的路径与预定义的期望路径的偏差的测试方法。 本文件的目的是在系统干预期间和之后评估车辆路径。 用于将车辆保持在期望路径上的校正转向动作可以由驾驶员、转向机或驾驶员辅助系统来施加。 通过使本文档开放用于开环或闭环测试，可以应用该测试方法来评估车辆在系统干预后如何保持在用户定义的车道标记内，并评估精度紧急制动系统和主动车道保持系统之间的相互作用。 本文件适用于配备先进紧急制动系统 (AEBS) 的重型车辆，包括 ISO 3833 中定义的商用车、商用车辆组合、公共汽车和铰接式公共汽车（最大重量超过 3.5 吨的卡车和拖车以及公共汽车和铰接式公共汽车）最大重量超过 5 吨的公共汽车，根据 ECE 和 EC 车辆分类，M3、N2、N3、O3 和 O4 类）。 注：该测试方法旨在评估整个车辆的行为，而不是定义 AEBS 的系统要求，这是在 ISO/TC 204 创建的相应标准中完成的。 [外文原描述]： ISO 19377:2017 describes test methods for determining the deviation of the path travelled by a vehicle during a braking manoeuvre induced by an emergency braking system from a pre-defined desired path. The purpose of this document is the evaluation of the vehicle path during and following the system intervention. The corrective steering actions for keeping the vehicle on the desired path can be applied either by the driver or by a steering machine or by a driver assistance system. By making this document open for either open-loop or closed-loop testing, it is possible to apply the test method for evaluating how well the vehicle can be kept within user-defined lane markings after the system intervention, and also for evaluating the precision of the interaction between the emergency braking system and an active lane keeping system. This document applies to heavy vehicles equipped with an advanced emergency braking system (AEBS), including commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO 3833 (trucks and trailers with maximum weight above 3,5 tonnes and buses and articulated buses with maximum weight above 5 tonnes, according to ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4). NOTE The test method is intended to evaluate the entire vehicle behaviour, not for defining system requirements for the AEBS, which is done in the respective standards created by ISO/TC 204.
