摘要
电动汽车最大的特点是能够实现再生制动,也就是能将部分用于摩擦制动的能量回收到电池组中。再生制动的引入会影响电动汽车制动时的安全性与稳定性,为了在解决上述问题的同时最大限度回收制动能量,针对纯电动物流车结构特点,建立了再生制动模糊控制器,提出了基于模糊控制的再生制动控制策略。在MATLAB/Simulink与ADVISOR中建立控制策略及整车模型,在典型工况下对模糊再生制动控制策略进行仿真分析,并与并联再生制动控制策略相对比。仿真结果表明,基于模糊控制的再生制动控制策略可以在保证制动安全性与稳定性的前提下显著提高制动能量回收效率,验证了控制策略的有效性。
ABSTRACT：The biggest feature of electric vehicle achieves regenerative braking, which is able to recover a part of the friction braking energy to the battery. The introduction of regenerative braking can affect the security and stability of electric vehicle braking. In order to solve this problem and recover braking energy to the maximum, a fltzzy control- ler of regenerative braking was built, and a regenerative braking control strategy was proposed according to the struc- ture of ＇electric logistics vehicle. The model of control strategy and vehicle were established based on MATLAB/Simu- link and ADVISOR, and then the fuzzy control strategy of regenerative braking and the parallel regenerative braking control strategy were simulated in the typical condition. The simulation results show that the regenerative braking con- trol strategy based on fuzzy control can improve the braking energy recovery rate under the premise of ensuring the safety and stability of braking, and the effectiveness of the control strategy is verified.
