摘　　要：为了提高汽车线控转向系统操纵稳定性,对其控制策略进行了研究。首先,通过分析系统运动学微分方程,采用Matlab/Simulink软件构建汽车线控转向系统的仿真模型。设计基于车轮转角的改进滑膜控制策略,在双移线变道工况和阶跃信号转向工况下进行多次联合仿真试验。结果表明,改进的滑膜控制具有良好的控制效果,此研究的线控转向系统可以提高车辆转向操纵的稳定性。In order to improve the handling stability of the automobile′s steering by wire system,its control strategy was studied.Firstly,by analyzing the differential equations of system kinematics,a simulation model is constructed using Matlab Simulink software.An improved sliding film control strategy based on wheel angle is designed,and multiple joint simulation tests are conducted under dual lane change and step signal steering conditions.The results show that the improved sliding film control has good control effect,and the wire controlled steering system can improve the handling stability of automobile′s steering.
