Abstract: An engine accessory drive (EAD) system for an engine includes a motor-generator (MGU) unit operably coupled to an accessory. The EAD system also includes a gearbox assembly, which includes a first gear train operably coupled to the MGU, and a second gear train operably coupled to an output of the engine. The gearbox assembly also includes a clutch selectively coupling the first gear train with a second gear train. The EAD system further includes a starter assembly, which includes a starter shaft operably coupled to the second gear train. The starter assembly also includes a starter pinion coupled to the starter shaft, and an actuator configured to selectively engage the starter pinion with a flywheel of the engine. Further yet, the EAD system includes an EAD controller configured to selectively operate the EAD system in one of a generator mode, an accessory drive mode, and a starter mode.

Abstract: Electric machine assemblies and methods of manufacturing and operating electric machine assemblies for internal combustion engines are provided. The electric machine assembly includes an electric machine configured to generate electric current by induction via a prime mover causing rotation of one of a rotor and a stator with respect to the other one of the rotor and the stator. The electric machine assembly also includes a torque transmitter including a rotating output driver coupled to the prime mover of the electric machine. The torque transmitter includes a rotating input driver configured to receive a rotary input transmitted from a crankshaft of an internal combustion engine. The rotating input driver is coupled to the rotating output driver to actuate the rotating output driver at a plurality of gear ratios.
