摘　　要：在不加入其他制动能量回收装置的前提下,单纯从控制策略结构的设计出发,使得能量回收分为收加速踏板阶段、滑行阶段和踩制动踏板阶段。整体设计以模糊控制作为辅助,同时与电机负载信号EM_Load_Signal的计算与修正相结合,使得电机快速、稳定和安全地进行制动能量回收。最后对多阶段控制策略和其他两种控制策略在中国轻型乘用车工况下进行联合仿真。从仿真结果看,所设计的多阶段能量回收控制策略在电池SOC和制动能量回收效率以及续驶里程贡献度上都有所提升,验证了该策略的合理性和可行性。The energy recovery is divided into the accelerator pedal recovery stage,the coasting stage and the braking pedal stage simply from the design of the control strategy structure without adding other braking energy recovery devices.In the overall design,fuzzy control is used as an aid in combination with the calculation and correction of motor load signal EM_Load_Signal,so that the motor can recover braking energy quickly,stably and safely.The multi⁃stage control strategy and the other two control strategies are jointly simulated under the working conditions of Chinese light passenger vehicles.It can be seen from the simulation results that the multi⁃stage energy recovery control strategy designed in this paper has improved the battery SOC(state of charge),braking energy recovery efficiency and driving range contribution,which verifies its rationality and feasibility.
