The invention relates to a dual-rotor motor-driven multi-mode dynamic coupling structure and a transmission method. The dual-rotor motor-driven multi-mode dynamic coupling structure comprises a dual-rotor asynchronous motor, a first planet carrier mechanism and a second planet carrier mechanism, the double-rotor asynchronous motor is provided with an inner rotor and an outer rotor; the double-rotor asynchronous motor serves as a power source, the first planet carrier mechanism and the second planet carrier mechanism are matched to achieve power output, the power output has a forward gear output mode and a reverse gear output mode, and the forward gear output mode comprises a large slope starting gear, a gear D1 and a gear D2; in a large slope starting gear state, the inner rotor and the outer rotor serve as power sources, and meanwhile output power is driven; and in the D1 gear or the D2 gear, one of the inner rotor and the outer rotor serves as a power source, and the other serves as a load. The double-rotor asynchronous motor is in transmission connection with the two-stage planet carrier mechanism, three gears can be achieved, two motors and clutches do not need to be adopted, the structure is simple, and cost is low.
