The invention discloses a hybrid vehicle and a gear shifting control method and device thereof, and relates to the technical field of gear shifting of hybrid vehicles. According to the gear shifting control method, when the hybrid power vehicle executes the gear shifting action, the torque change value output to a gearbox by an engine is obtained, and a driving motor of the hybrid power vehicle is controlled to conduct output torque compensation according to the torque change value, so that the gearbox outputs the wheel end required torque of the hybrid power vehicle. According to the method, through the output torque of the driving motor, gear shifting pause caused by the change of the output torque of the engine in the gear shifting process is compensated, it is guaranteed that torque output of the hybrid power vehicle in the gear shifting process can follow the torque required by the wheel end, and then the smoothness of power output of the hybrid power vehicle in the gear shifting process is improved.

    本发明公开了一种混合动力车辆及其换挡控制方法和装置,涉及混合动力车辆换挡的技术领域。换挡控制方法在混合动力车辆执行换挡动作时,获取发动机输出至变速箱的扭矩变化值,根据扭矩变化值控制混合动力车辆的驱动电机进行输出扭矩补偿,以使变速箱输出混合动力车辆的轮端需求扭矩。该方法通过驱动电机的输出扭矩,补偿了换挡过程中发动机输出扭矩变化引起的换挡顿挫,保障混合动力车辆在换挡过程中的扭矩输出能够跟随轮端需求扭矩,进而提高了混合动力车辆换挡过程中动力输出的平顺性。
