ABSTRACT:
A vehicle drive system has an engine and a multispeed transmission which can be selectively coupled with an energy storage system. The energy storage system includes a hydraulic member which is operable as a pump to store hydraulic fluid under pressure in an accumulator during certain drive system operations and to operate as a motor to use the stored fluid to drive the vehicle through the transmission, to start the engine or both during other drive system operations.
