上述两个文件分别是遗传算法和包括侧倾的三自由度车辆模型，遗传算法(GA)主要用于辨识三自由度车辆模型参数，主要辨识的参数有前后轴等效侧偏刚度、整车绕X轴和Z轴的转动惯量、质心位置、悬架侧倾刚度和阻尼等关系参数。(The above two files are respectively a genetic algorithm and a three-degree-of-freedom vehicle model including a roll. The genetic algorithm (GA) is mainly used to identify the parameters of a three-degree-of-freedom vehicle model. The main parameters identified are the front and rear axle equivalent cornering stiffness and the entire vehicle. Rotational inertia, centroid position, suspension roll stiffness, and damping relationship parameters around the X and Z axes.)
