插电式混合动力汽车换档动力中断优化研究

Research of Optimization of Power Interrupt of Plug-in Hybrid Vehicle

基于对插电式混合动力驱动系统的原理研究,介绍了该动力驱动系统的工作原理及换档时序,并考虑到机械式自动变速器在换档动力中断方面的局限性,提出了在降扭、调速、升扭等方面改善动力中断性能的策略方法,最终通过实验测试验证缩短了插电式混合动力汽车的换档动力中断时间。

Based on the principle of plug - in hybrid power drive system, working principle and shift sequence are demonstrated. Considered the limits of AMT system on power interrupt aspect, the control strategies including roll off, speed control, roll on are put forward. Finally, the shift power interrupt time has been decreased through experiments.
