ABSTRACT:
The present invention provides an alternator starter accessory drive system for a hybrid vehicle. The starter alternator accessory drive system includes a planetary gear set having a first, second, and third planetary member. An engine is operatively connected to the first planetary member, and a first motor/generator is operatively connected to the second planetary member. A torque transfer device operatively connects a plurality of accessories to the third planetary member. A second motor/generator is operatively connected to either the third planetary member or the torque transfer device. Engine output is transferable through the planetary gear set to drive the accessories at a selectable rate, and the first and second motor/generators are controllable to run the accessories while the engine is off and to re-start the engine.
