The invention provides an electric drive multi-gear transmission system and a control method thereof. The system comprises a first motor (EM1), a second motor (EM2), a first intermediate shaft (S3), a second intermediate shaft (S4), an output shaft (S5), a third gear shifting device (A), a fourth gear shifting device (B) and a fifth gear shifting device (D). Two paths of output power of the first motor and the second motor are subjected to power coupling through a coupling gear pair with an idle wheel, so that dual-motor driving is realized; the first gear shifting device and the second gear shifting device are arranged to control two paths of power, the first gear shifting device controls even gears (the second gear, the fourth gear and the sixth gear) and controls odd gears (the first gear, the third gear shifting device, the fourth gear shifting device and the fifth gear shifting device), six different gears are formed through the third gear shifting device, the fourth gear shifting device and the fifth ge
