摘要
在P2双离合器自动变速器混合动力构型发动机停机控制理论基础上,设计了P2混合动力发动机停机核心动态工况的控制策略,并给出相应控制过程的动力控制目标值计算公式和分析。通过对所设计的停机控制策略进行仿真及实车测试,证明了该控制策略能有效实现P2混合动力的停机功能,同时,其在车辆平顺性上也取得了很好的效果。
Engine stop control strategy of P2 hybrid engine in dynamic condition is designed based on engine stop control strategy principle of hybrid vehicle equipped with P2 DCT,power control target value calculation formula and analysis for corresponding control process are given.The designed stop strategy is simulated and tested,which proves that this control strategy can effectively enable P2 hybrid stop function,meanwhile,it also has good effect on vehicle ride comfort improvement.
