中文摘要：
为提高整车能量利用效率并延长续驶里程,同时弥补电机再生制动能力的不足,针对某款四驱混合动力轿车,结合其动力系统具有2个后轮毂电机与ISG电机的结构特征,设计了基于制动防抱死系统（ABS）的串联式电液复合制动系统,并实现轮缸压力闭环控制。综合考虑ECE法规与再生制动约束条件,设计了理想制动力分配策略;在紧急制动工况下,采用改进型自寻优理论得到ABS最优滑移率区间,建立紧急制动时ABS液压制动与电机再生制动协调控制策略。结果表明：所开发的复合制动协调控制策略充分利用了电机的再生制动功能,有效回收了制动能量,并保证了紧急制动工况下车辆的行驶安全性。
英文摘要：
In order to improve energy efficiency,extend vehicle driving range,and remedy the deficit of motor regenerative braking capacity,aimed at a 4WD hybrid electric vehicle and combining the structure feature of power system with two rear hub motors and an ISG motor,the electro-hydraulic series compound braking system based on anti-lock braking system（ABS）was designed,and close loop control of wheel cylinder pressure was achieved.Considering Economic Commission for Europe regulation（ECE regulation）and regenerative braking constraints,the ideal braking force distribution strategy was designed.Furthermore,in order to deal with the emergency braking condition,the improved self-optimizing theory was used to obtain the optimal ABS slip rate range,and the coordination control strategy of ABS hydraulic brake and motor regenerative braking was developed.The results show that the proposed strategy can make full use of the regenerative braking ability of motors,braking energy can be recovered effectively and safety can be ensured in emergency braking condition.
