A differential generation power distribution system to drive an all wheel driving carrier by having a rotational kinetic energy output end of a rotational power unit coupled to an intermediate transmission and control interface device containing a main transmission comprised of controllable clutches and gear shifting control means to drive an intermediate differential gear set; one differential output end of the intermediate differential gear set to drive the front end transmission and thus the front end load; another differential output end of the intermediate differential gear set to drive an input end of a rotation part of a first electric machine of the rotational electric machine assembly; the output end of the rotation part of a second electric machine of the rotational electric machine assembly to directly or through the transmission drives the rear end load; and the rotational electric machine assembly for being subject to the drive control device to regulate and control the power distribution between the front end and the rear end loads.
