Abstract

A power train arrangement for a work vehicle with an engine may include an infinitely variable power source (“IVP”). An energy storage device may be configured to receive energy from the IVP for storage and to provide stored energy from the energy storage device to power one or more components of the IVP. A transmission may be configured to relay power from the engine and from the one or more components of the IVP to other components of the vehicle. A transient power event may be identified, during which a present operating state of the engine does not provide sufficient power for operations of the work vehicle. The energy storage device may be caused to provide stored energy to power the one or more components of the IVP source and thereby to provide power to the transmission.
