摘　　要：在总结切换型混杂系统稳定性的研究方法的基础上,对某切换型混杂系统进行了详细的建模仿真和分析,由实验数据对比说明结论的正确性。着重阐述集成换档规则、控制策略、液力系统特性以及发动机、变矩器、变速箱等各个模型,构成多学科综合性仿真课题的完整过程,并给出稳定性证明方法。提供一种研究换档过程动态特性及控制方法的新思路。Based on summarizing the methods of verifying the stability characteristic of switched hybrid systems, modeling, simulation and analysis was made for a certain switched hybrid system, and the experiment data proves the correctness of the conclusion. The main focuses are on the integrated shift rules, control method, hydrodynamic system specifications and the models of engine, torch converter, and gear box, etc. It is a full process of the simulation task with proof on the stability, which is composed of multiple synthesized subjects. A new thinking method of studying dynamic characteristic and control strategy of shifting activities was provided.
