The invention provides a motor driving system and a control method thereof, and relates to the technical field of vehicles. The motor driving system comprises a first motor, a first braking device, a planetary gear train, a second braking device, a differential mechanism assembly, a clutch device and a second motor which are sequentially and coaxially arranged, the first motor is used for providing first speed section driving, and the second motor is used for providing second speed section driving larger than the first speed section. The clutch device is used for connecting or disconnecting the differential assembly with a second motor shaft of the second motor, the first braking device is used for connecting or disconnecting the first braking device with the first motor shaft, and the second braking device is used for connecting or disconnecting the second braking device with the gear ring. According to the invention, an efficient working area driven by the motor can be widened, power non-interruption type gear shifting of the motor driving system and power coupling driving of the double motors are realized, and the smoothness is relatively good.
