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 planetary gear train, a first clutch device, a differential mechanism assembly, a second clutch device and a second motor which are sequentially and coaxially arranged, 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 planet carrier in the planetary gear train and the differential mechanism assembly; and the second clutch device is used for connecting or disconnecting a second motor shaft of the second motor and the differential assembly. 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.
