电动汽车动力传动系统仿真研究

STUDY ON SIMULATION FOR THE POWER TRAIN OF ELECTRIC VEHICLE

迫于环境污染和石油资源短缺的压力下,电动汽车成了适应21世纪汽车工业的可持续发展的重要考虑的发展方向。由于使用电机驱动,电动汽车还有其独特的优点。本文通过理论分析,对电动汽车的动力传动模型进行了讨论,给出了电动汽车控制策略和工作模式,给出相关的控制参数。通过MATLAB/Simulink建立了电动汽车的动力传动模型,其仿真结果表明该模型是合理的。

Under the stress of environment pollution and the scarcity of oil source,Electric Vehicle（EV） becomes an important consideration in the twenty-first century in order to get the sustainable development of Automobile industry.The EV also have other advantage of using motors to drive.Based on theoretical analysis,the EV powertrain schedule and components are discussed in this thesis.The control strategy and the working modes of the selected EV Powertrain schedule are determined;the relative control system,the parameters designing and matching also are discussed at the same time.Based on MATLAB/Simulink＇s the parameters designing method of the EV Powertrain is brought out.The simulation shows that the modes of the selected EV Powertrain is reasonable.
