Abstract
A combined hybrid drive system and electro-hydraulic machine includes a hybrid drive system that is adapted to decelerate a rotatably driven mechanism, accumulate the energy resulting from such deceleration, and use the accumulated energy to subsequently accelerate the rotatably driven mechanism. An electro-hydraulic machine is operatively connected to the hybrid drive system and is adapted to be operated in one or more of a plurality of modes to improve the performance of the hybrid drive system.
