AMT汽车模糊三参数换挡规律研究

为了使AMT汽车自动变速器换挡能够反映路况与车况变化,更好地满足汽车换挡平顺性要求,提出了AMT汽车模糊三参数换挡控制。论文首先给出了模糊三参数换挡控制原理,接着设计了模糊三参数换挡控制器,最后给出了长安羚羊AMT轿车模糊三参数换挡仿真,并与模糊两参数换挡进行了比较。结果表明,采用模糊三参数换挡比采用模糊两参数换挡更加符合驾驶员的换挡经验和习惯,比传统计算法求解换挡规律更简便,易于实现,鲁棒性更强。

Fuzzy three parameter shift schedule research of AMT car

In order to have the shift of AMT car can reflect road circumstance and vehicle state,satisfy the required of ride comfort in shift,author presented fuzzy three parameter shift control technology.At first,given the control principle of three parameter shift in the paper,then the controller of fuzzy three parameter shift is designed,at last,the MATLAB/simulink of fuzzy three parameter shift of ChangAn Lingyang AMT car,and compared with fuzzy two parameter shift.The result demonstrated that shift adopted fuzzy three parameter is accord with driver’s experience and custom more than fuzzy two parameter shift,it is more simple and easy to realize and more stronger Robustness than shift with traditional calculate method.
