Zusammenfassung:	The double epicyclic transmission for a motor vehicle between an engine (1) and the wheels (2) has two electric machines (3,4) and two epicyclic trains (5,15) connected to the engine and the machines. A mechanical coupling switches the transmission from one to the other, each mode corresponding to a different transmission ratio. Claims include a power transmission method.
