The invention relates to new energy automobile parts, in particular to a dual-motor hybrid power automatic transmission. According to the dual-motor hybrid power automatic transmission, a dual-input-shaft structure is adopted, the two dual input shafts are parallel to an output shaft, and the first input shaft can transmit the power of a first motor as well as the power of an engine by being connected with the engine through a clutch; the second input shaft can transmit the power of a second motor; meanwhile, the power of the engine can also be separated from the first input shaft through the clutch, the power of the first motor can also be separated from the first input shaft through a second gear and fourth gear synchronizer, and the power of the second motor can also be separated from the second input shaft through a first and third synchronizer. By the adoption of the dual-motor hybrid power automatic transmission, all driving states of starting and stopping of the engine, the pure electric mode, the series mode, the parallel mode and the parallel-serial mode can be realized, unpowered interruption type automatic gear shafting of each power source can also be achieved, and therefore driving comfort is guaranteed.
