摘要
介绍了一种适用于混合动力汽车(HEV)的行星机构动力耦合装置,该装置利用行星机构的两自由度结构,通过两组离合器和一组制动器限制一个自由度,从而解决了HEV的"多动力输入-单动力输出"问题。在分析行星机构运动特性的基础上,建立了行星机构动力耦合装置的数学模型。研究了HEV在各种工作模式下行星机构动力耦合装置的控制要求,并确立了离合器和制动器的模糊控制策略。试验验证了行星机构动力耦合装置的控制效果。
This paper introduced a planetary mechanism coupling device for HEV,which used two-degree of freedom structure of planetary mechanism,through two sets of clutches and a set of brakes to restrict one degree of freedom,so that the issue how to make HEV ＂multi-power input single-power output＂ was solved.A mathematical model of planetary mechanism dynamic coupling device was built after analyzing the characteristics of motion to planetary mechanism.The control requirements of planetary mechanism coupling device for HEV under all working conditions were researched,and a fuzzy control strategy was established for control of dynamic coupling device clutches and brake.Finally,the work results of planetary mechanism coupling device were verified by tests.
