ISO 18375:2016描述了一种在低摩擦路面上测定车辆横摆稳定性的开环试验方法。它适用于重型车辆,即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)。
该方法适用于配备电子偏航稳定控制系统的车辆。
由于本试验的结果在很大程度上取决于路面摩擦的局部和临时变化,本国际标准给出了关于保持摩擦水平尽可能均匀的建议,以确保试验结果的良好再现性。
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.
