为了充分回收电动汽车制动过程中的制动能量，达到延长续驶里程和节约能源的目的，针对后驱纯电动客车进行了最佳制动能量回收控制策略的研究。在分析制动能量回收系统结构的基础上，考虑驱动电机和动力电池对电机制动力大小的限制，提出了一种最佳制动能量回收控制策略，该策略在保证制动安全的前提下，能回收尽可能多的制动能量。并基于Cruise和Simulink联合仿真平台，搭建了整车仿真模型，进行了仿真验证，仿真结果表明在中国典型城市循环工况中采用该制动能量回收控制策略，所回收的制动能量占制动过程中消耗的动能的比例可达24.7%，占制动系统所消耗的总能量的比例可达36.2%，节能效果明显。

In order to fully recover the braking energy of electric vehicles in the braking process, to extend the driving range and to save energy, the control strategy of optimal braking energy recovery for rear-drive pure electric bus is studied. By analyzing the structure of the braking energy recovery system and considering the restrictions of drive motor and power battery for the size of the motor bra-king force, a control strategy for optimal braking energy recovery is proposed to recycle braking ener-gy as much as possible on the premise of ensuring the braking safety. The vehicle simulation model is built and a simulation is conducted by using an integrated simulation platform of Cruise and Simu-link. The simulation results show that the proportion that recyclable braking energy accounts for the kinetic energy consumed in the process of braking can reach 24. 7% and the proportion that recycla-ble braking energy accounts for the braking energy can reach 36. 2% by using this control strategy of braking energy recovery in typical urban driving cycle of China. The effect of energy saving is obvi-ous.
