Abstract
An infinitely-variable power-branching transmission with two operating modes. The transmission components are distributed between two power paths connecting in parallel a heat engine to vehicle wheels, including at least first planetary trains, two electrical machines, and a reduction stage. A third planetary train co-operates with control members to establish the two transmission operating modes and to switch there between.
