摘　　要：为了进一步提高纯电动汽车电机再生制动回收率,增加电动汽车续航里程,对复合电源纯电动汽车再生制动控制策略展开研究。建立串并联可变结构复合电源储能系统,利用SVPWM调制方法控制电机三相整流器的转矩输出,以路面特征值数学模型识别路面状态,建立不同附着系数下以f线组、r线组、理想I曲线和ECE法规线为制动力分配基础的再生制动力控制策略。利用MATLAB/SIMULINK仿真软件建立复合电源和再生制动控制系统仿真模型,嵌入ADVISOR纯电动汽车整车模型,进行不同制动强度下的再生制动过程仿真,并选取CYC_ECE和CYC_UDDS两种道路循环工况,对嵌入的控制策略模型进行整车仿真,与ADVISOR原有模型的仿真结果进行对比分析。仿真结果表明,所设计的改进型再生制动控制策略能量回收效果更佳,能有效提高续驶里程。In order to further improve the recovery rate of electric motor regenerative braking and increase the range of electric vehicle,the control strategy of composite power pure electric vehicle regenerative braking is studied.The energy storage system of series parallel variable structure composite power supply is established,and the torque output of motor three-phase rectifier is controlled by SVPWM modulation method.Based on the mathematical model of pavement eigenvalue,the control strategy of regenerative braking force with F-Line group,R-line group,ideal i-curve and ECE regulation line as the basis of braking force distribution is established.The simulation model of composite power supply and regenerative braking control system is established by using MATLAB/SIMULINK simulation software,and the whole vehicle model of pure electric vehicle is embedded by ADVISOR to simulate the regenerative braking process under different braking intensity.In addition,two road cycle conditions,CYC_ECE and CYC_UDDS,are selected to simulate the embedded control strategy model and compare the simulation results with the original model of ADVISOR.The simulation results show that the improved regenerative braking control strategy has better energy recovery effect and can effectively improve the driving range.
