摘　　要：为解决机械式自动变速器有级换挡对车辆动力不连续性的影响,提高换挡品质,提出了一种基于功率换挡的动力总成控制策略,设计了传统车辆及混合动力车辆基于功率换挡的动力接口。仿真和实验数据表明,与现有动力换挡策略相比,基于功率换挡控制方式显著提高了车辆的驾驶舒适性及动力连续性。In order to solve the vehicle power discontinued transmission which influenced by the shift of the automated mechanical transmission and improve the shift quality,a new powertrain control strategy based on power shift is put forward. The traditional and hybrid powertrain interface based on this new strategy is designed. According to the result of the simulation and actual test,the comfort of driving and the continuity of power are obviously improved based on the power shift control strategy.
