纯电动汽车低速转向差速控制模型
Low speed steering differential control model for pure electric vehicle
摘要
Abstract
This paper focuses on a pure electric vehicle driven by four wheel motors and on the basis of the efficient and simplex thought of the differential control technology,and then establishes the Ackerman steering differential model which is suitable for the pure electric vehicle by using the Matlab/ Simulink tool.On the basis of the established model,this paper simulates and researches the speed characteristics of the four wheels of the pure electric vehicle under the different speeds and rotating angels,and then makes the comparison and analysis of the speeds of the four wheels when the pure electric vehicle is steering.We also compare the simulated wheel speed with the actual wheel speed,and make the analysis of the limitation of the steering differential model.The analysis results indicate that the used Ackerman steering differential model is suitable for the steering differential pure electric vehicle completely,it can provide a reliable theoretical basis for the differential control.关键词
