混合动力汽车是一种应用比较广泛的电动汽车,它的最大的特点之一是再生制动系统,通过再生制动能有效地提高能量回收率。影响制动能量回收的因素有:制动电机、制动力分配、控制策略、电池荷电状态、使用环境等。本文针对混合动力汽车在制动力分配方面的问题加以研究,通过对传统汽车制动原理的分析并结合其新特点,提出用于并联式系统的分配控制制动力的策略。
Hybrid electric vehicle is a widely used electric vehicle, one of its most prominent features is the regenerative braking system, through the regenerative braking can effectively improve the energy recovery rate. Affect the braking energy recovery factors are: brake motor, brake force distribution, control strategy, battery state of charge, the use of the environment. In this paper, the issue of hybrid power distribution in braking force is studied. Based on the analysis of traditional automobile braking principle and its new features, the strategy of distributing and controlling braking force for parallel system is proposed.
