Disclosed in the present disclosure are a dual-motor coupling driving system and a control method therefor. The dual-motor coupling driving system comprises a driving apparatus and a transmission apparatus; the driving apparatus comprises a first motor and a second motor; the first motor and the second motor are coaxially arranged, and an output shaft of the first motor passes through the second motor; the transmission apparatus comprises a first input shaft, a second input shaft, a first gear pair, a second gear pair, a third gear pair, a fourth gear pair, a first clutch unit, a second clutch unit, a first intermediate shaft, a second intermediate shaft, and a system output shaft; the first motor is connected to the first input shaft; the second motor is connected to the second input shaft; the first clutch unit is fixed on the system output shaft; and the second clutch unit is fixed on the second intermediate shaft. According to the present disclosure, dual motors are coaxially arranged, four dual-motor gears are realized by means of four gear pairs, and the dual motors both can participate in transmission, and thus, orderly upshifting without power interruption can be realized in the process of gear shifting.
