轮毂驱动电动汽车整车操纵稳定性仿真研究

Simulation Study on the Handling Stability of In-wheel Motor Electrical Vehicle

在MATLAB/Simulink环境下,建立了永磁同步电机仿真控制模型以及七自由度整车模型,主要针对轮毂驱动电动汽车操纵稳定性进行了仿真分析。用转向盘角阶跃输入与三角波输入模拟两种典型工况,分析整车模型的操纵稳定性。仿真结果表明,所建整车模型的操纵稳定性与实际车辆相近,运用该模型能进行车辆操纵稳定性仿真研究。

In-wheel motor electrical vehicle＇ s handling and stability was analyzed by MATLAB/Simulink simulation. A seven degrees of freedom electric vehicle model and permanent magnet synchronous motor model was built. The handling stability of the whole vehicle model was analyzed by simulating two kinds of typical working conditions with steering wheel angle step input and triangle wave input. The simulation results showed that the handling stability of the whole built vehicle model was consistent with that of the actual one, and this model could be used for vehicle handling and stability performance.
