重型商用车辆和公共汽车. 航向稳定性试验方法. 正弦停滞试验

[中文适用范围]： 本国际标准描述了一种在低摩擦路面上测定车辆横摆稳定性的开环测试方法。适用于重型车辆，即商用车辆、商用车辆组合、公共汽车和铰接式公共汽车，如ISO 3833所定义的（根据ECE和EC车辆分类，最大重量超过3.5吨的卡车和拖车，以及最大重量超过5吨的公共汽车和铰接式公共汽车，类别M3、N2、N3、O3和O4）。该方法适用于配备电子横摆稳定性控制系统的车辆。由于测试结果很大程度上取决于路面摩擦系数的局部和临时变化，本国际标准给出了保持摩擦系数尽可能均匀的建议，以确保测试结果的良好重现性。 [外文原描述]： ISO 18375:2016 describes an open-loop test method for determining the yaw stability of a vehicle on a low friction road surface. It applies to heavy vehicles, that is 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). The method is intended for vehicles equipped with electronic yaw-stability control systems. As the results of this test depend largely on local and temporary changes in road surface friction, this International Standard gives recommendations about keeping the friction level as uniform as possible for good reproducibility of the test results.
