A hybrid drivetrain for a vehicle may include a co-drive manipulator having a first input configured to be driven by an internal combustion engine, and a second input configured to be driven by a first electric machine. The hybrid drivetrain may also include a selective booster having first and second planetary gearsets, each of the first and second planetary gearsets having a rotating component secured for rotation with a rotatable shaft driven by the co-drive manipulator, such that a rotational input received at the second planetary gearset from a second electric machine selectively drives the output shaft with a plurality of gear ratios including at least a speed reduction gear ratio and a speed increasing gear ratio.

Dual electric machine co-drive system with selective booster of electric machine

A hybrid assembly having a single input and a single output. The hybrid assembly is compactly packaged and achieves a wide range of gear ratios. The hybrid assembly may be used in a vehicle power train with or without an additional transmission.

Single-input and single-output hybrid system

A modular electrically variable transmission includes at least one of a sun-shared module and a sun and ring-shared module assembled to form a two-module electrically variable transmission having a shiftable motor speed reducer subassembly and an electrically variable transmission subassembly. The sun-shared module includes a first motor-generator, an input, and primary and secondary planetary gear sets each having respective primary and secondary ring gears, carriers and associated pinion gears. The pinion gears are in meshing engagement with a single first shared sun gear that is non-rotatably coupled to the first motor-generator. The sun and ring-shared module includes a second motor-generator, a second input, a second shared sun gear and a shared ring gear, and primary and second secondary planetary gear sets. The secondary planetary gear set includes a secondary carrier supporting outer and inner pinion gears. The second shared sun gear is non-rotatably coupled to the second motor-generator.

Multi-mode modular electrically variable transmission

A hybrid assembly for a vehicle is provided having a single input and a single output. The hybrid assembly is compactly packaged and achieves a wide range of gear ratios. The hybrid assembly may be used in a vehicle power train with or without an additional transmission.

Single input and single-output hybrid system

A hybrid assembly having a single input and a single output is provided. The hybrid assembly may be operated in electronically variable, fixed gear, direct gear, and locked modes.
