Energy Savings of a Hybrid Truck Using a Ravigneaux Gear Train

摘要: The series–parallel powertrains for high-power vehicles have complex architectures. They generally require multiple planetary gear trains with several clutches. maintenance and durability of the clutches are nonetheless not relevant on-board implementation. In this paper, a new architecture Ravigneaux train without is proposed. complexity then reduced. objective paper to illustrate benefits such powertrain in terms energy savings comparison conventional truck. Due mechanical constraints train, control scheme vehicle design. A functional description, Energetic Macroscopic Representation, used organize scheme. Simulation results, rules-based management strategy, show reduction fuel consumption from 6% 19% depending on driving cycles. To prove use as power split device, basic operating modes validated open-loop test bed.
