Introducing Hydraulic-Electric Synergy into Hybrid Transmission Using the Free-piston Engine Technology 2007-01-4112

The purpose of this paper is to present a concept of a new hybrid transmission based on a free piston engine technology [1, 2]. The novelty of the system is a hydraulic-electric synergy. Two main components of the concept are: the continuously variable displacement linear hydraulic pump and the linear electrical actuator, mounted in parallel with the pump.
It is shown that having hybrid transmission with hydraulic-electric synergy, new possibilities arise in overall hybrid transmission optimization that is not possible with existing hybrid transmissions.
