摘　　要：通过分析描述轮胎摩擦力与滑移率关系的Magic模型,根据其关系曲线形状进行假设,利用二阶系统传递函数的直接识别方法,得到了由指数函数和双曲函数组成的简单建模方法,所建模型能够准确地描述摩擦因数与滑移率间的变化关系。Based on analysis of Magic formula which describes relationship of tire friction and making presumption according to its curve, a new simple approach was put method of direct identification transfer function of second-order system. The model new method is composed of exponential and hyperbolic functions, which can be us relationship between friction force and slip rate correctly and conveniently. and slip rate, forward using derived using ed to describe relationship between friction force and slip rate correctly and conveniently.
