摘要
针对轮毂电机独立驱动电动汽车电子差速的问题进行研究,通过对轮毂电机驱动和传统汽车的差速装置驱动进行比较分析.根据阿克曼汽车转向模型和各个轮毂电机独立可控,提出基于MATLAB/simulink搭建汽车理想状态下的转向仿真建模.仿真结果表明:Ackermann-Jeantand转向几何模型可以计算出给定方向盘角度下的各个车轮的实际速度,进而分别控制各个轮毂电机的转速实现电动汽车电子差速的目的,满足汽车低速转向的要求,对进一步研究电动汽车独立转向电子差速等问题具有一定的借鉴意义.
An original electronic differential system for an in-wheel motor drive electric vehicle was proposed. This paper compared in-wheel motor drive electric vehicle with traditional differential device drive car. According to the string principle of Ackerman and the fact that each in-wheel motor can be independently controlled,an ideal mode of vehicle steering model based on MATLAB/Simulink was presented. The simulation results show that the steering model of Ackermann-Jeantand can calculate each wheel's speed under the given angle of steering wheel to control the speed of each wheel to achieve electronic differential. The simulation results also show that it meets the requirement of low speed steering of automobile and may give references for four-wheel independent electric vehicle steering.
