摘　　要：电动车在行驶过程中,路面及车身等情况不断变化,为了兼顾车辆在不同行驶工况下的行驶平顺性及侧倾稳定性,针对电机式主动稳定杆系统提出了三种工作模式,控制器根据车身的状态信号选择合适的工作模式。基于MATLAB/Simulink,建立了14自由度整车模型和电机式主动稳定杆模型,在多种工况下进行了仿真分析。仿真结果表明:电机式主动稳定杆系统根据不同的外部条件或行驶工况选择合适的工作模式,能有效提高车辆的侧倾稳定性与行驶平顺性。As the pavement and the body status were constantly changing when the electric vehicle was in the driving processes,considering the ride comfort and roll stability of the vehicles under different driving conditions,three kinds of working modes were proposed for the electric active stabilizer bar systems,and the controller selected the appropriate operating mode according to the body status signals.Based on MATLAB/Simulink,a 14 degree-of-freedom vehicle model and the electric active stabilizer bar model were established,simulation was carried out under various driving conditions.The simulation results show that,the proposed control strategy may improve the roll stability and the ride comfort of the electric vehicles.
