The invention provides a gear shifting control method and device of a hybrid vehicle and a storage medium. The method comprises the steps that when a target hybrid vehicle is in a hybrid mode, after an HCU receives a gear shifting requirement, the HCU controls the vehicle to conduct twist clearing operation; after the twist clearing is finished, the AMT is controlled to adjust the gear to the neutral gear; the real-time synchronous rotating speed is adjusted by adjusting the engine torque and the motor torque in real time, the AMT is controlled to conduct gear engaging operation under the condition that the real-time synchronous rotating speed reaches the target synchronous rotating speed, and the gear is adjusted to the target gear; and after the gear engaging operation is completed and the motor torque is adjusted to reach the motor target torque, it is determined that the gear shifting process is completed. According to the scheme, the torque change of the motor is used for replacing untwisting and returning of the engine, the torque response rate is increased, the gear shifting time is shortened, the dynamic property of the whole vehicle is improved, meanwhile, the transient response of the engine is reduced, and the transient smoke intensity of the engine in the gear shifting process is reduced.

    本申请提供了一种混动车辆的换挡控制方法、装置与存储介质。该方法包括:在目标混动车辆处于混动模式,HCU收到换挡需求之后,HCU控制车辆进行清扭操作;清扭结束,控制AMT将档位调至空挡;通过实时调整发动机扭矩和电机扭矩以调整实时同步转速,使实时同步转速达到目标同步转速的情况下控制AMT进行挂档操作,以将档位调至目标档位;在完成挂档操作之后,调节电机扭矩达到电机目标扭矩后,确定完成换挡过程。本方案通过电机的扭矩变化替代发动机的清扭和还扭,提升了扭矩响应速率、减少了换挡时间、提升了整车动力性,同时减少了发动机的瞬态响应且降低了换挡过程中的发动机瞬态烟度。
