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.
