摘　　要：轮胎是汽车唯一接地部件,它提供汽车运动需要的所有驱动、转向和制动力。轮胎力学是汽车动力学的基础。汽车动力学及其控制技术的进一步发展有赖于精确的轮胎动态模型技术。该文综述了轮胎动态模型发展历史与现状,这包括:汽车操稳仿真模型、汽车舒适性仿真模型和汽车疲劳载荷仿真模型。从建模方法的角度,即基于物理的、基于实验的和基于结构的三类方法,对轮胎动态模型的优缺点进行了梳理。可以预计:轮胎动态模型的未来发展将以基于结构的先进轮胎模型为主,与汽车动力学仿真、汽车主动安全系统开发深度融合,并最终走向汽车—轮胎—道路相互作用定量化理论。Tire is the only link between tire and road, which provides al force and moments for vehicle motion including driving, steering and braking. Tire mechanics is the base for vehicle dynamics, which progress depends on to a large extent the precise tire dynamical model. This paper reviews the state of the art for tire dynamical models, including handing tire model, ride comfort model, and durability load simulation model. The advantages and disadvantages for three tire modeling approaches, i.e. simple physics based, empirical based and structure based, are compared. It can be concluded that the fufure of the tire model lies in the so caled advanced tire model, i.e. structure based model wil gain more advances and interest in both academics and industries, the tire dynamical model wil be integrated with vehicle dynamics simulation and vehicle active safety system development. The vehicle-tire-road indication theory wil be ultimate goal of the research.
