摘　　要：针对线控转向四轮独立驱动电动汽车建模问题,论文应用Car Sim与Matlab/Simulink联合仿真进行了整车模型的搭建与仿真分析。确定了线控转向系统中的动力学微分方程,基于Matlab/Simulink软件建立了线控转向系统模型,将Car Sim中的内燃机模型修改为四轮独立驱动电动汽车模型,并将线控转向系统模型嵌入到Car Sim中去,搭建了线控转向四轮独立驱动电动汽车整车模型。选取方向盘角阶跃工况对所建立的模型进行仿真验证。结果表明:线控转向四轮独立驱动电动汽车具有良好的响应特性。For the modeling of steer-by-wire electric vehicle with four independent drive wheels, the vehicle model is built and the simulation is analyzed. Determine the dynamics differential equation of the steer-by-wire system. The steer-by-wire system model is established by Matlab/Simulink software. The model of the internal combustion engine in the Car Sim is modified to four-wheel independent drive electric vehicle model. The steer-by-wiresystem model is embedded into the Car Sim and the model of steer-by-wire electric vehicle with four independent drive wheels is built. The steering wheel angle step condition is selected to verify the established model.The results show that the wire control steering wheel drive electric car has a good response.
