电动车电子差速控制方法的研究

Research on Electrical Differential Control System of Electric Vehicle

随着能源危机和环境保护等问题日益受到关注,电动车成为世界汽车工业的研发热点之一。采用前轮转向方案,确定了电子差速转向时的控制策略,并利用Ackerman-Jeantand转向模型,结合电动车的结构特点,计算了电子差速过程中随转向角度变化的各车轮车速。在Matlab/Simulink仿真环境下建立了电动车电子差速控制算法的仿真模型,并对电子差速转向时的各车轮车速进行了仿真计算,通过数据图形验证了电动车在转向时的稳定运行。

With the energy crisis deteriorating and evnvironmental pollution aggravating,electric vehicle （EV） is an main trend of the vehicle research and development in the world.In the article the front wheel steering is adopted and control system of an electronic vehicle is designed.Then based on Ackerman-Jeantand steering model and the structure of the EV, the velocity of each wheel is caculated during the steering process.Lastly, a simulation model of the electronic differential control system is established in Matlab/Simulink simulation environment and the simulaion results arc gained to approve the steadibility of the steering of an EV.
