The invention relates to a hybrid power system and a control method thereof and a vehicle, the hybrid power system comprises an engine, multiple sets of speed changing parts, multiple clutches, a battery pack and a motor, the transmission ratios of the multiple sets of speed changing parts are different, an output shaft of the engine is connected with the input sides of the multiple sets of speed changing parts, and the output shaft of the engine is connected with the input sides of the multiple sets of speed changing parts. The output sides of the multiple sets of speed changing parts are in transmission connection with wheels, each set of speed changing parts in the multiple sets of speed changing parts is provided with the clutch so as to control meshing and separation of the speed changing parts, the battery pack is electrically connected with the motor, and an output shaft of the motor is in transmission connection with the wheels. According to the hybrid power system, different speed changing parts can be selected to be in transmission connection with the engine and the wheels according to the factors such as the load of the engine, the vehicle running road condition and the running speed, so that the power output of the engine is optimized, and the energy economy of the whole vehicle is guaranteed.
