Abstract
A power train and related vehicle provides multi-mode power transmission. A first continuously variable power source (“CVP”) may convert rotational power received by the engine for transmission to a second CVP. A variator assembly may receive rotational power from the second CVP at a first input and directly from the engine at a second input. A control assembly may allow the power train to shift between multiple modes, such as a series mode, a split-path mode, and a direct mode. The control assembly may provide seamless shifting between at least two of these modes.
