摘　　要：为了满足混合动力电动汽车（HEV）制动安全性的要求并使其有效地进行能量回收,在分析比较了不同能量回收制动控制策略的基础上,针对EQ7200HEV-C并联型混合动力汽车的制动系统设计开发了一种全新的综合制动控制策略.该控制策略采用逻辑门限控制逻辑对传统的液压制动力矩进行动态调整,采用模糊控制逻辑对电机施加的能量回收制动力矩进行动态调整,两者的有效结合确保了制动安全下的能量有效回收.仿真及试验结果验证了该控制策略的有效性和稳定性.In order to improve hybrid electric vehicles （HEVs） ＇ effectivenes in energy regeneration when ensuring the safety in braking, this paper presents a novel combined control strategy for the braking system of the parallel hybrid electric vehicle EQ7200HEV-C on the basis of the analysis and comparison of different regenerative braking control strategies. In this control strategy, a threshold control logic is used to dynamically adjust the traditional hydraulic braking torque, and a fuzzy control logic approach is used to dynamically adjust the regenerative braking torque from the electric motor. Under this combined control strategy, a good compromise between the hydraulic braking torque and the regenerative braking torque can be obtained for the vehicle.The simulation and experiment results show that the proposed strategy is steady and effective.
