The invention discloses a control method of a variable-torque primary and secondary hub motor, and the motor comprises a hub installation part which is provided with a primary motor module and a secondary motor module. The mother motor module comprises a mother motor stator fixed on the periphery of the hub mounting part, a mother motor rotor is mounted on the periphery of the mother motor stator in a matched manner, and a hub motor output shell is fixed outside the mother motor rotor; the sub-motor module comprises a sub-motor stator indirectly fixed to the hub mounting part, a sub-motor rotor is mounted on the periphery of the sub-motor stator in a matched mode, a sub-motor speed reduction assembly is arranged outside the sub-motor rotor, and a sub-motor output shell is arranged on the periphery of the sub-motor speed reduction assembly in a matched mode; a child-mother switching clutch is arranged between the child motor output shell and the hub motor output shell. The device and the control method have the advantages of being simple in structure, small in size, fast in clutch engagement response, reasonable and accurate in control method and the like.
