本文件规定了根据ISO？11026中规定的闭合曲线试验，将车辆模型的模拟结果与现有车辆的测量试验数据进行比较的方法。验证的目的是证明，车辆动力学仿真与集成电子稳定控制（ESC）系统相结合，可以在闭合曲线试验期间预测物理车辆的侧倾和偏航稳定性行为，包括ESC系统干预。模拟方法可以是硬件在回路（在HiL试验台上使用原始电子控制单元（ECU））或软件在回路，基于与实际车辆中ECU相同来源生成的软件代码。本文件适用于重型车辆，包括ISO？3833中定义的商用车、商用车组合、公交车和铰接式公交车（根据ECE和EC车辆分类，M3、N2、N3、O3和O4类，最大重量超过3.5吨的卡车和拖车，以及最大重量超过5吨的公交车和铰接式公交车）。

This document specifies a method for comparing simulation results from a vehicle model to measured test data for an existing vehicle according to closing-curve tests as specified in ISO 11026. The purpose of the validation is to demonstrate that the vehicle dynamics simulation, combined with an integrated electronic stability control (ESC) system, can predict the roll and yaw stability behaviour of a physical vehicle, including the ESC system interventions, during a closing-curve test. The simulation method can be either hardware-in-the-loop [with the original electronic control unit (ECU) on a HiL test stand] or software-in-the-loop, based on a software code generated from the same source as for the ECU in the real vehicle. This document applies to heavy vehicles, including commercial vehicles, commercial vehicle combinations, buses and articulated buses as defined in ISO 3833 (trucks and trailers with a maximum weight above 3,5 tonnes and buses and articulated buses with a maximum weight above 5 tonnes, according to ECE and EC vehicle classification, categories M3, N2, N3, O3 and O4).
