在考虑再生制动安全性和稳定性的情况下，以能量回收最大化为目标提出了一种并联再生制动控制策略。然后根据实验获取的电池、电机和无级变速器效率特性，基于传动系统效率最优的原则，优化得到再生制动过程中电机转速和无级变速器速比的最佳控制规律，并搭建整车仿真模型且在NEDC循环工况进行仿真分析。仿真结果表明，相比于常用的电机效率最优控制策略，本研究提出的控制策略能够充分利用动力部件的效率特性，进一步提高了能量回收率。

In the case of considering security and stability of regenerative braking,a parallel regenerative braking control strategy was proposed with the objective of maximizing the energy recovery.Then according to the efficiency characteristics of battery,motor and continuous variable transmission which acquired from experiment, an optimization procedure was implemented to optimize motor and CVT’s best control strategy during regenerative braking with the principle of optimal powertrain efficiency,and the vehicle simulation model was established and simulation analysis was carried out under NEDC driving cycles.The simulation result indicates that,compared with traditional optimal motor efficiency control strategy,the proposed strategy enables to take full advantage of power parts’efficiency characteristics and further improve the recover rate of regenerative braking energy.
