The invention discloses a dual-motor hybrid power transmission and a control method thereof. The dual-motor hybrid power transmission comprises a first driving motor assembly, a second driving motor assembly, a first input shaft assembly, a second input shaft assembly, an intermediate shaft assembly, a differential mechanism assembly, a driving shaft assembly, an idler shaft assembly, an engine and a clutch which are parallel to one another, the engine is connected with the first driving motor assembly through the clutch, the first input shaft assembly is connected with the first driving motorassembly, and the driving shaft assembly is connected with the second driving motor assembly. By means of multi-gear ingenious layout of the two driving motors, power gear shifting under pure electric driving of the whole vehicle is achieved; series drive of the whole vehicle is achieved, and hybrid parallel drive of a single motor or double motors can also be achieved. Different driving modes are selected according to different working conditions while efficient energy transmission of the transmission is kept, and energy utilization of the whole vehicle is maximized; and through reasonable gear shaft layout, the size of the transmission is optimized.
