摘　　要：再生制动是目前电动汽车的研究热点。以制动时电机制动转矩恒定及启动时超级电容电能优先利用为目的,设计了一种新的再生制动主电路拓扑结构和控制策略。在Simulink仿真环境下搭建系统数学模型,在理论上对再生制动系统进行仿真和研究,最后分析对比实验和仿真数据。结果表明,此再生制动控制策略在车辆制动过程中能够有效地控制电机制动转矩和回收动能,提高了电动汽车的续驶里程。The pure electric vehicles （PEV） research is mainly focus on regenerative barking. For the purpose of constant braking torque when braking and priority use of super capacitor energy when starting,a new main circuit topology and regenerative braking control strategy was designed. Then built a mathematical model of the system in Simulink simulation environment, the simulation and theoretical analysis of regenerative bra- king system have been completed. Finally,it is discussed to analyze the test data and simulation results. The results show that the regenerative braking control strategy can effectively control braking torque and recycle energy during braking and increase driving range of electric vehicles.
