According to the steering road feeling feedback torque control method based on driver arm parameter identification provided by the invention, the recursive least square method based on the index window is adopted to carry out online identification on arm parameters, and the estimation method has the advantages that disturbance torque does not need to be applied to a steering wheel; the driving habits of the drivers are classified according to the driver road feeling characteristic parameters obtained through identification, the steering gain of the road feeling feedback torque is adjusted according to the driving habits of different drivers, the ideal road feeling feedback torque is determined by adopting a method based on system modeling, personalized design is achieved, the driving comfort is improved, and the driving experience of the drivers is improved. And personalized driving requirements of drivers with different driving habits can be met.
本发明提供一种基于驾驶员手臂参数辨识的转向路感反馈力矩控制方法,采用了基于指数窗的递归最小二乘法进行手臂参数的在线辨识,这一估计方法的优点是不需要在方向盘上施加干扰力矩,并通过辨识得到的驾驶员路感特征参数对驾驶员的驾驶习性进行分类,根据不同驾驶员的驾驶习性调节路感反馈力矩的转向增益,采用基于系统建模的方法确定理想的路感反馈力矩,实现个性化设计,提升驾驶舒适性,满足不同驾驶习性驾驶员的个性化驾驶需求。
