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.
