    Abstract: A power-driven system includes: a differential; a power output shaft configured to link to a power input end of the differential; multiple input shafts; and a first motor generator. The differential includes a first planet carrier, a second planet carrier, a first planet gear, a second planet gear, a first ring gear, and a second ring gear. The first planet gear and the second planet gear are respectively disposed on the first planet carrier and the second planet carrier and respectively meshed with the first ring gear and the second ring gear. One input shaft of the multiple input shafts is configured to selectively link to the power output shaft, and another input shaft of the multiple input shafts is configured to link to the power output shaft. The first motor generator is configured to link to the one input shaft of the multiple input shafts.

    Abstract: The present disclosure discloses a shifting control method for a hybrid vehicle. The shifting control method includes: detecting operating parameters of the hybrid vehicle, where the operating parameters of the hybrid vehicle includes vehicle speed, vehicle acceleration as reflected from an accelerator-pedal signal and a current gear of the hybrid vehicle; determining a work mode of the hybrid vehicle; performing speed adjustment and shifting control to the first motor-generator according to a work mode and the operating parameters of the hybrid vehicle to implement shifting control of the hybrid vehicle, where the work mode includes an electric-vehicle mode and a hybrid-electric-vehicle mode. The method considers performing speed adjustment and shifting control under various working conditions. This improves smoothness and comfort of the vehicle and enlarges the use scope. The present disclosure further discloses a power transmission system of a hybrid vehicle and a hybrid vehicle.
