摘要
混合动力汽车的制动是在液压制动力矩和能量回收制动力矩协同工作下完成的。在分析多种制动策略基础上,文章提出了基于门限值控制和模糊控制的制动策略,以实现制动力矩的动态分配,在保证汽车制动稳定的前提下,实现制动能量最大程度的回收;仿真结果表明,该控制策略能够达到较理想的制动效果。
The braking of hybrid electric vehicle（HEV） is completed by the collaboration of regenerative and hydraulic braking torques.Based on the analyses of different kinds of braking control strategies for HEV,a braking control strategy based on threshold control and fuzzy control is proposed in this paper in order to realize the dynamic distribution of the total braking torques and achieve maximum braking energy recovery under the premise of automobile braking stability.The simulation results show that this control strategy has an ideal braking effect.
