Abstract
A system for hydraulic hybridization of a motor vehicle according to embodiments of the present invention includes a planetary gear mechanism including a first, second, and third planetary member and planet gears, wherein one of the first, second, and third planetary members is a sun gear, one is a ring gear, and one is a carrier; an engine, the engine including a crank shaft; a transmission, the transmission including a transmission input shaft; and a hydraulic pump/motor, the pump/motor including a pump shaft; and wherein the first planetary member is mechanically coupled to the pump shaft, wherein the second planetary member is mechanically coupled to the crank shaft, wherein the third planetary member is mechanically coupled to the transmission input shaft, and wherein the hydraulic pump/motor is not part of a hydrostatic transmission system.
