混合动力大客车起步AMT离合器控制研究

摘要

Starting clutch control is always the key point in AMT system .Single axle parallel hybrid electric bus has different starting ways due to the existence of multiple power sources ,which puts forward new requirements for clutch control .This paper increases sectional control on the basis of traditional PID control method .The AMT clutch starting control model of hybrid electric bus is es-tablished and simulated .The simulation results show this clutch control model can meet the different requirements of starting inten-tion .Its performance is greatly improved .%起步离合器控制一直是AM T系统的重点和难点 ,单轴并联式混合动力大客车由于多个动力源的存在 ,起步方式也变得多样化 ,对离合器控制提出了新的要求.在传统P ID控制方法的基础上增加了分段控制 ,建立了混合动力大客车AM T离合器的起步控制模型并进行仿真.结果表明 :该离合器控制模型能够满足不同起步意图的要求 ,其性能得到很大改善.
