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 shaft and a second shaft which are arranged in parallel, the first shaft is sequentially and coaxially provided with a first motor, a differential mechanism assembly, a first clutch device and a second motor, the second shaft is sequentially and coaxially provided with a first intermediate shaft, a second clutch device and a second intermediate shaft, and the first motor is used for providing first speed section driving; the second motor is used for providing second speed section driving which is greater than the first speed section; the first clutch device is used for connecting or disconnecting a second motor shaft of the second motor and the differential mechanism assembly; and the second clutch device is used for connecting or disconnecting the first intermediate shaft and the second intermediate shaft. 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.
