The invention discloses a hybrid power gearbox, a drive assembly, a control method and a vehicle. The hybrid power gearbox comprises a first input shaft, a second input shaft, an output shaft, a multi-gear gear pair and a synchronizer. The first input shaft is in transmission connection with an engine; the engine is in transmission connection with the first motor; the second input shaft is in transmission connection with a second motor; the output shaft is parallel to the first input shaft and the second input shaft and arranged side by side and is used for being in transmission connection with wheels, the multi-gear gear pair is arranged between the first input shaft and the output shaft and between the second input shaft and the output shaft, and the synchronizer is selectively in transmission connection with one or more gears in the multi-gear gear pair so as to achieve transmission connection between the first input shaft and the output shaft and/or between the second input shaft and the output shaft. According to the hybrid power gearbox, coupling between the wheels and different power sources is achieved through the connection action of the synchronizer, a clutch or a planetary gear is not needed, the system cost is low, the structure is compact, and the occupied space is small.
