摘要
针对轮毂电机驱动电动汽车前轮转向,四轮差速控制问题进行了研究。在Car Sim里建立了电动汽车整车模型,根据运动学模型,设计出基于转矩控制的电子差速器。并在Matlab/Simulink里建立了四轮轮毂电机驱动电动汽车电子差速器仿真模型,通过Car Sim与Matlab/Simulink联合仿真,选择双移线试验工况和蛇形试验工况进行了验证,试验结果表明:电子差速器实现了更好的轮速跟踪和驱动力矩再分配,能够有效提高电动汽车的行驶稳定性。
For in-wheel motor drive electric vehicle front wheel steering, four wheel differential control problem is studied.Electric vehicle model is established in the Car Sim software. According to the kinematic model, the electronic differential is designed based on torque control. And electronic differential simulation model of the four wheel in-wheel motor electric vehicle is built in Matlab / Simulink. Through the joint simulation of Car Sim and Matlab / Simulink, the double lane experiment and slalom experiment are selected for verification. Experiment results show that the electronic differential achieved a better wheel speed tracking and driving moment redistribution, can effectively improve the driving stability of the electric vehicle.
