Multi-mode infinitely variable transmission that provides seamless shifting

[0031]The following describes one or more example embodiments of the disclosed powertrain arrangement for energy storage and delivery, as shown in the accompanying figures of the drawings described briefly above. Various modifications to the example embodiments may be contemplated by one of skill in the art.

[0032]In various known configurations, one or more planetary gear sets may be utilized to combine the power output of an IVP and an engine (e.g., an internal combustion engine). For example, in a planetary gear set a first component of the gear set (e.g., a ring gear) may receive power from the engine, a second component of the gear set (e.g., a sun gear) may receive power from the IVP, and a third component of the gear set (e.g., a planet gear carrier) may sum the power from the engine and the IVP at the output of the gear set. (For convenience of notation, “component” may be used herein, particularly in the context of a planetary gear set, to indicate an element for transmission o
