摘　　要：针对线控转向汽车主动转向控制,研究了基于自适应模糊PI理论的主动转向控制方法。应用Matlab/Simulink软件搭建线控转向系统模型,并与Car Sim软件联合仿真,将Car Sim中的传统转向系统汽车改进为线控转向系统汽车。基于横摆角速度反馈的主动转向控制策略,设计了主动转向自适应模糊PI控制器。选择高速双移线仿真实验,在Car Sim中对所研究的控制算法进行了仿真验证,并与无主动转向控制和主动转向PI控制对比分析。结果表明:线控转向汽车主动转向自适应模糊PI控制相对于PI控制和无控制,能够使汽车更好跟踪期望,提高汽车行驶稳定性。For the active steering control of the vehicle steering-by-wire system, the adaptive fuzzy PI control for active steering is studied in this paper. The model of the steering-by-wire system is built by using Matlab / Simulink. Through the cosimulation of Car Sim and Simulink, the traditional steering system of the vehicle in Car Sim is changed to the steering-by-wire system. The adaptive fuzzy PI controller is designed for the active steering control based on yaw rate feedback strategy. The high-speed double-lane change condition is selected to verify the control algorithm in Car Sim. The results show that active steering control based on fuzzy PI control makes the vehicle follow the expected state and enhance the vehicle stability better compared to the PI control and no control.
