The invention relates to the technical field of vehicle control, in particular to a two-gear dual-motor planet row power dividing driving system. The system comprises a first motor, a second motor and an engine. The first motor is connected with the engine through a power dividing device, and a gear ring output shaft of the power dividing device is connected with the second motor or the output shaft through a gear shifting device. The second motor is connected with the parallel shaft speed reducer and is output through the output shaft after two-stage speed reduction and torque increase; and the first motor, the second motor, the engine and the gear shifting device are respectively connected and controlled by the control device. According to the system, the output torque of the driving device under the low-speed working condition and the vehicle dynamic property are improved, the power interruption in the gear shifting process is eliminated, the idling loss of a transmission system under the pure electric working condition is reduced, the transmission efficiency is improved, the rear axle speed ratio requirement is reduced, and the system can be matched with a more efficient and lightweight small-speed-ratio rear axle.
