文章针对魔术公式轮胎模型仿真建模问题，提出了基于遗传算法的魔术公式轮胎模型参数辨识方法。以动力学仿真软件TRUCKSIM 7.0内置的某轮胎侧向力数据为例，采用构建的辨识方法对其魔术公式参数进行辨识，经过遗传算法1555次迭代后，拟合结果与原始数据之间的误差平方和小于优化目标值0.1，两者之间吻合良好。通过算例分析表明遗传算法是实现魔术公式轮胎模型非线性、多参数辨识的一种有效手段。

The genetic algorithm is proposed to determine these parameters of magic formula tyre model in this paper. Based on the data of lateral tyre force from TRUCKSIM 7.0, the proposed genetic algorithm is used to determine these parameters of magic formula tyre model. After 1555 iterations, the sum of squares of errors between the calculations and original data is less than 0.1. The simulation analysis indicates that the genetic algorithm provides an effective method for the nonlinear and multi-parameter determination of the magic formula tyre model.
