Study of vehicle dynamics aggregates possibilities to enhance performance, safety and reliability, such as the integration of control systems, usually requiring knowledge on vehicle's states and parameters. However, some critical values are difficult to measure or are not disclosed. For this reason, dynamics and stability analysis of six-wheeled vehicles are compromised, and available information on this matter is limited. In this context, this paper proposes the estimation of the cornering stiffness of a 6x6 vehicle by an inverse problem approach applying the Levenberg–Marquardt (LM) method. The algorithm required data from field experiments and from simulations of a vehicle model during a double-lane change manoeuvre developed using ${\mathrm{S}\mathrm{i}\mathrm{m}\mathrm{u}\mathrm{l}\mathrm{i}\mathrm{n}\mathrm{k}}^{\circledR }/{\mathrm{M}\mathrm{A}\mathrm{T}\mathrm{L}\mathrm{A}\mathrm{B}}^{\circledR }$. Experimental and theoretical values for the vehicle yaw rate were combined through LM method for cornering stiffness estimation. The excellent agreement between measured and simulated yaw rate indicates that the proposed model and the estimated parameters properly represent the vehicle dynamics response.

车辆动力学研究汇集了提高性能、安全性和可靠性的可能性，例如控制系统的集成，通常需要了解车辆状态和参数。然而，一些临界值难以衡量或未公开。出于这个原因，六轮车辆的动力学和稳定性分析受到影响，关于这件事的可用信息是有限的。在这种情况下，本文提出了通过应用 Levenberg-Marquardt (LM) 方法的逆问题方法来估计 6x6 车辆的转弯刚度。该算法需要来自现场实验和车辆模型在双车道变换机动期间使用开发的数据${\mathrm{秒}\mathrm{一世}\mathrm{米}\mathrm{你}\mathrm{升}\mathrm{一世}\mathrm{n}\mathrm{克}}^{\circledR }/{\mathrm{米}\mathrm{一个}\mathrm{吨}\mathrm{升}\mathrm{一个}\mathrm{乙}}^{\circledR }$. 车辆横摆率的实验值和理论值通过 LM 方法结合用于过弯刚度估计。测量的和模拟的偏航率之间的极好一致性表明所提出的模型和估计的参数正确地代表了车辆动力学响应。
