The invention provides a range-extended power assembly for realizing non-inductive range extension, a control method and a vehicle, relates to the field of new energy vehicles, and can be applied to range-extended electric vehicles. The range-extended power assembly comprises a generator, a motor controller and a rotary transformer sensor. The generator is used for being connected with the extended-range engine through the driving shaft. The extended-range engine is used for outputting power generation torque to the driving shaft to drive a rotor of the generator to rotate. The rotary sensor is used for detecting the position angle of the rotor. The motor controller is used for outputting current to the generator to control the generator to output vibration suppression torque to the driving shaft in the process that the range extending engine is used for outputting power generation torque to the driving shaft to drive a rotor of the generator to rotate. The directions of the vibration suppression torque and the power generation torque are opposite, and the magnitude of the vibration suppression torque changes along with the change of the position angle of the rotor indicated by the resolver sensor. According to the scheme, the position detection precision is high, vibration and noise can be obviously suppressed, and the vehicle comfort and the NVH level are improved.
