The invention discloses a gear-shifting control method of a hybrid electric vehicle. The gear-shifting control method comprises the following steps of detecting operating parameters of the hybrid electric vehicle, judging the working modes of the hybrid electric vehicle, and carrying out speed governing gear-shifting control over a first electric motor generator according to the current working mode of the hybrid electric vehicle and the operating parameters of the hybrid electric vehicle so that the hybrid electric vehicle can achieve gear-shifting control, wherein the operating parameters of the hybrid electric vehicle comprise the speed, the accelerator pedal signals and the current gear of the hybrid electric vehicle, and the working modes comprise the pure electric mode and the hybrid power mode. According to the method, speed governing gear-shifting of motors in various working conditions is taken into consideration, the smoothness and the comfort of the whole vehicle are improved, and the application range is expanded. The invention further discloses a power transmission system and the hybrid electric vehicle.
