摘要
为了更加深入地开展电动汽车动力学控制研究,建立了基于线控转向的四轮轮边电机独立驱动的电动汽车整车动力学仿真研究平台,通过选择典型的New York和开环控制的稳态圆周转向试验仿真工况,对所搭建的电动汽车的驱动和转向特性进行了仿真验证。结果表明:所搭建的电动汽车动力学仿真平台在2种典型工况下均能较为合理地反映出四轮独立驱动电动汽车的轮边电机输出转矩和转向系统响应特性。为四轮轮边电机电动汽车控制算法的改进及性能验证提供良好的平台。
The structure of hub motor driving and steering -by -wire system of electric vehicle was designed to set up corresponding mathematical models in order to further research on electric vehicle dynamic control. EV dynamic simulation platform based on SBW was established to test driving and steering characteristics through the typical New York and steady- state circular steering that was open loop control. The simulation results showed that EV dynamic platform can more reasonably reflect output torque of hub motor and response characteristics of steering system under two typical conditions that can provide the good foundation for the research on the improvement of control algorithm and performance verification of EV with 4WID.
