Abstract: A powertrain includes an engine with a crankshaft rotating on a first axis, motor/generator unit (MGU), belted drive system, transmission, actuator assembly, and controller. An MGU rotor shaft rotates about a second axis. The belted drive assembly has a first pulley connected to the crankshaft, a second pulley selectively connected to the rotor shaft, and an endless rotatable drive element that connects the pulleys. The transmission is connected to the flywheel via an input clutch. The actuator assembly has a third axis parallel to the first and second axes, a linear actuator(s), pinion gears translatable along the third axis to selectively engage the first and second gear elements, and overrunning clutches to passively disengage the pinion gears from the first or second gear element. The controller transmits control signals to the MGU and linear actuators to command a control state via translation of the pinion gears.

Abstract: A vehicle includes a chassis, engine, transmission, electric machine operable to selectively power the engine, and an electrical system. The electrical system includes a DC propulsion energy storage system (P-ESS) and a DC auxiliary ESS (A-ESS). Positive terminals of the two ESSs are electrically connected. The A-ESS negative terminal connects to the chassis as an electrical ground. The P-ESS negative terminal is not connected to ground, such that voltage levels of the P-ESS negative terminal float with respect to ground. A power invertor module (PIM) is connected to the MGU via an AC propulsion bus, and to the positive and negative terminals of the P-ESS. Positive input terminal and output terminals of a DC-DC converter system are tied together and connected to positive terminals of the P-ESS and A-ESS. A negative input terminal of the DC-DC converter system is electrically connected to the negative terminal of the P-ESS.

Abstract: An electric drive unit (EDU) is configured for driving a first and second wheel of a vehicle. The EDU includes a rotor, a stator, a first planetary gear set, a second planetary gear set, and a pair of engagement mechanisms. The first planetary gear set is operatively connected to the rotor and rotates about the drive axis in response to rotation of the rotor to transmit torque to the first wheel. The second planetary gear set is operatively connected to the rotor and rotates about the drive axis in response to rotation of the rotor to transmit torque to the second wheel. Rotation of the rotor causes each of the planetary gear sets to rotate about the drive axis. Each engagement mechanism is selectively engages a respective one of the planetary gear sets to vary the torque transmitted to the respective wheel.
