摘　　要：通过分析和研究混合动力汽车在低附着系数路面制动时制动系统的工作状态与要求,针对具有独立的电机回馈制动控制系统和独立的液压制动控制系统的混合动力汽车,设计了一种新颖的回馈制动与防抱死制动机电复合模糊控制系统。该两层分级控制系统顶层协调控制电机回馈制动与液压制动过程工况分配,底层协调控制力矩分配与调节。对控制策略与方法进行了研究并通过仿真与试验进行验证,结果表明车辆制动性能良好,能量回收制动力矩和液压制动力矩能够协同工作,部分制动能量被回馈储存,控制策略与方法有效且鲁棒性好。Based on the analysis and research of working state and demand related to hybrid electric vehicle braking system when braking on low adhesion coefficient roads, a novel electro-mechanical hybrid antiskid braking system using fuzzy logic for a hybrid electric vehicle having a regenerative braking system operatively connected to an electric motor and a separate hydraulic braking system was proposed. This system has a two-layer hierarchical control structure. The first layer is responsible for harmonious adjustment or interaction between a regenerative braking system and an antiskid braking system. The second layer is responsible for torque distribution and adjustment. Control strategy and method for coordination between regenerative braking and antiskid braking was developed. The simulation and experimental results reveal that braking performance of the vehicle is perfect, regenerative and antiskid braking torque are assorted with each other, significant amount of energy can be recovered, and the proposed control strategy and method are effective and robust.
