The invention discloses a transmission sliding downshift change intention control method, which is characterized in that a first synchronizing device is fixed with a first input shaft, and the first synchronizing device is selectively matched with a second gear of the input shaft so as to connect or cut off power transmission from an engine to an output gear; the control method further comprises a third power assembly, the third power assembly comprises a second driving motor, a third input shaft, a third gear and a third synchronizing device, the second driving motor is matched with the third input shaft, and the third gear and the output gear are rotationally arranged on the third input shaft. The third gear is meshed with the input shaft first gear; the third synchronizer is fixed with the third input shaft; the third synchronizer selectively cooperates with an output gear to connect or disconnect power transmission from the second drive motor to the output gear. According to the invention, power from a plurality of power sources is efficiently transmitted to an output shaft, and fuel efficiency can be improved.
