本文件规定了用于计算轮胎横向力的通用轮胎模型和模型参数，用于根据ISO？14791.该轮胎模型由易于理解的特性参数化，这些特性可以从轮胎测量数据中估计出来。如果没有轮胎数据，可以使用本文档中提出的参数。该文件的一个典型应用领域是关于道路横向和侧倾稳定性的各种车辆组合配置的比较和排序。这种评估通常在接近公共道路典型的恒定速度水平下进行，通常高于40？公里/小时。然而，轮胎模型可用于高速和低速操纵。当纵向力不显著（通常小于10？峰值纵向摩擦利用率的%。轮胎模型可用于从零到轮胎标称法向力两倍的法向力。该轮胎型号专为中度侧滑条件而开发；在轮胎滑移角超过15°的情况下，小心使用该模型是很重要的。该轮胎模型适用于在偏航和侧倾平面中操作的车辆模型，其自然包括操纵期间车轮之间的垂直载荷传递。轮胎模型也可以用于复杂性较低的模型，例如纯偏航平面模型。本文件适用于重型车辆，包括ISO？中定义的商用车、商用车组合、公共汽车和铰接式公共汽车。3833（最大重量超过3.5吨的卡车和拖车以及公共汽车和根据ECE和EC车辆分类，最大重量超过5吨的铰接式公共汽车，类别为M3、N2、N3、O3和O4）。

This document specifies a generic tyre model and model parameters for calculating lateral tyre forces, for use in lateral stability simulations of heavy commercial vehicle combinations with test cases according to ISO 14791. This tyre model is parameterized by easily understandable characteristics which can be estimated from tyre measurement data. If tyre data is not available, the parameters proposed in this document can be used.

One typical application area of this document is the comparing and ranking of various vehicle combination configurations with respect to on-road lateral and roll stability. Such an assessment is usually performed at close to constant speed levels typical for public roads, usually higher than 40 km/h. The tyre model, however, can be useful for both high- and low-speed manoeuvring.

This tyre model is relevant for representing the lateral performance of tyres on a vehicle combination when the longitudinal forces are insignificant, typically less than 10 % of the peak longitudinal friction utilization. The tyre model can be used for normal forces ranging from zero to twice the nominal normal force of the tyre. This tyre model has been developed for moderate lateral slip conditions; it is important that the model is used with care for scenarios where tyre slip angle exceeds 15°.

This tyre model is suitable for vehicle models operating in the yaw and roll plane which naturally include vertical load transfer between the wheels during manoeuvring. The tyre model can also be used in models with less complexity such as pure yaw plane models.

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).
