The invention relates to the technical field of vehicle control, and particularly discloses a gear shifting control method of a P2 hybrid vehicle. According to the gear shifting control method of a P2hybrid vehicle, when the vehicle shifts a gear, an engine adjusts a rotating speed, meanwhile, a power motor reduces a torque, and a gearbox is out of gear and selects the gear to a target gear; power interruption time in a gear shifting process is reduced; and clutch wear is reduced, the engine actively adjusts the speed in the gear selecting process of the gearbox, then the clutch is quickly combined to synchronize the rotating speed of a first shaft of the gearbox to a rotating speed value of the target gear within an extremely short time, a rotating speed difference between the first shaft and the output shaft of the gearbox in a gear engaging process and an impact on a gear wheel in the gearbox in the gear engaging process are reduced, and vehicle gear shifting smoothness is improved.
本发明涉及汽车控制技术领域,具体公开了一种P2混合动力型车辆的换挡控制方法。本发明提供的P2混合动力型车辆的换挡控制方法,在车辆换挡时,发动机调整转速的同时使动力电机降扭矩、变速箱摘挡并选挡至目标挡位,减少了换挡过程中动力中断的时间,降低了离合器的磨损,发动机在变速箱选挡的过程中主动调速,然后离合器快速结合将变速箱一轴转速在极短时间内同步至目标挡位的转速值,减少挂挡过程中变速箱一轴与输出轴的转速差以及挂挡过程中对变速箱内的齿轮的冲击,提高了车辆换挡平顺性。
