| 摘 要： | 提出了一种基于主动前轮转向横摆稳定性控制方法,以横摆角速度和质心侧偏角为控制目标。采用鲁棒性较强的模糊控制方法对汽车稳定性进行控制。建立了整车线性二自由度模型,以反馈系统中的误差信号及其变化率作为模糊系统的输入设计了模糊控制器,通过控制横摆力矩来实现车辆稳定性的控制。对转向盘阶跃输入信号和正弦输入信号两种工况分别进行了仿真研究。通过分析仿真结果,该控制方法能有效地控制车辆横摆角速度和质心侧偏角,提高车辆转向时的稳定性,同时能有效的降低驾驶员的操纵负担。

| Abstract: | A fuzzy control method is proposed to improve vehicle yaw stability by the integrated control of active front steering.The control strategy control yaw rate and side slip angle.The method of the vehicle stability control is fuzzy control,which have more robust method.Two-degree-of-freedom model of vehicle is set up in this paper,the error signal of the feedback system and its rate of change as the importation of the fuzzy control system,by controlling yaw moment to achieve the vehicle stability control.A si... |
