The invention relates to a dual-motor multi-gear electric drive assembly device and a control method. The assembly device comprises a first motor, a second motor and a multi-gear transmission. The multi-gear transmission comprises a first input shaft assembly, a second input shaft assembly, an output shaft assembly and a differential mechanism assembly. The output shaft assembly is connected withthe first input shaft assembly, the second input shaft assembly and the differential mechanism assembly, the first input shaft assembly is further connected with the first motor, the second input shaft assembly is further connected with the second motor, and the differential mechanism assembly is used for being connected with two driving half shafts of a vehicle. The first input shaft assembly comprises a first-gear synchronizer, the second input shaft assembly comprises a second-gear synchronizer, or the output shaft assembly comprises a first-gear synchronizer and a second-gear synchronizer.The output shaft assembly or the differential mechanism assembly comprises a parking ratchet wheel. The device can realize three functions of driving, gear shifting and parking, is high in working efficiency and good in economy, can effectively reduce unnecessary electromagnetic loss and mechanical loss of double motors, and can realize unpowered interruption and impact-free gear shifting.
