摘　　要：对汽车制动能量再生系统的机电制动力分配控制方法进行了研究,以电机制动效能为依据划分制动模式,提出了常规液压制动与再生制动力(电机制动)协调控制方法,建立了相应的再生制动系统机电制动力分配控制策略模型,并且对控制模型进行了仿真分析.结果表明,该再生制动系统机电制动力分配控制策略能够保证汽车前后轴制动力分配随理想制动力分配I曲线变化,实现良好制动性能,制动过程中增加了电机制动率,从而提高了汽车制动能量的回收率.The motor-friction braking force distribution control of regenerative braking system was investigated. Based on the motor braking efficiency, the braking mode was classified. The braking force distribution control strategy of regenerative braking combining with a general hydraulic braking was proposed. The relevant strategy model was set up. Simulation of the model was carried out. The results indicate that the motor-friction braking force distribution control strategy can assure good braking performance, increase the motor brake rate during braking, and thus improve the reclaiming ratio of braking energy.
