1. A vehicle two-power-source dual driving assembly, wherein, the vehicle two-power-source dual driving assembly comprises two sets of driving units that are symmetrically arranged, the two sets of driving units connect to a same set of vehicle axle half shafts and have a same gear shifting sequence, each of the sets of driving units is provided with a power source and an automatic transmission, and the power source and the automatic transmission are an integrated structure;
the two automatic transmissions are symmetrically arranged in two separated boxes, and there is no connection between the two automatic transmissions;
each of the automatic transmissions is connected to one of the vehicle axle half shafts, and each automatic transmission has two mutually switchable speed ratios;
wherein each of the automatic transmissions is provided therein with an input shaft, an intermediate shaft and an output shaft that are parallel,
the input shaft is connected to the power source in the same set of driving unit, the output shaft is connected to a left half shaft or right half shaft of the vehicle axle half shaft;
the input shaft is connected to the intermediate shaft via a first gear train;
a second gear train and a third gear train that have different transmission ratios are provided between the intermediate shaft and the output shaft, and the intermediate shaft and/or the output shaft are/is provided thereon with a clutch for switching between the second gear train and the third gear train.
