摘要
设计了轮边电机驱动和线控转向系统的结构,建立了电动汽车的线控转向系统和轮边电机的数学模型。采用Carsim与MATLAB/Simulink软件进行联合仿真,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的平台;通过选择典型的New York和开环控制的稳态圆周转向试验工况仿真工况,对所搭建的电动汽车的驱动和转向特性进行了仿真验证。仿真试验结果表明:所搭建的电动汽车动力学仿真平台在两种典型工况下均能较为合理地反映出四轮独立驱动的电动汽车的轮边电机输出转矩和转向系统响应特性,为开展四轮轮边电机独立驱动的电动汽车动力学控制研究奠定了良好的基础。
The structure of hub motor driving and steering-by-wire system electric vehicle(EV)was designed in order to set up corresponding mathematical models.Carsim and MATLAB/Simulink co-simulation was adapted to establish EV dynamic simulation platform of four hub motor independent-driven based on steering-by-wire and choose the typical New York and open loop control of steady-state circular to test driving and steering character.The simulation results showed that the EV dynamic platform can more reasonably reflect output torque of hub motor and response characteristics of steering system under two typical condition.It is the good foundation for the research on the dynamics control method of EV with four-wheel independent-driven based on hub motor by simulation.
