POWERTRAIN COMPRISING AN OPTIMIZED ENERGY RECOVERY SYSTEM

摘要

The invention relates to a powertrain for a vehicle comprising: - a thermal (12) engine for driving a driveline of the vehicle; - a power split transmission device (34) comprising at least three separate input/output couplings (36, 40, 44), wherein: - a first coupling (36) of said power split transmission device (34) is coupled to a flywheel (38) and to a fluidic or electric machine (60); - a second coupling (40) of said power split transmission device (34) is coupled to the driveline of the vehicle, - a third input/output coupling (44) of the power split transmission device (34) is coupled to a friction brake (70) adapted to control the torque applied on said third coupling (44).
