A starter and accessory drive system and method for hybrid drive vehicles is provided. The invention isolates the accessory drive system from the transfer of torque between a starter motor and the crankshaft of the engine. In one embodiment, a dedicated flexible drive member transfers torque from the starter motor to the crankshaft to re-start the engine. In another embodiment, a torque transfer control is employed to selectively apply torque from the starter motor to the accessory drive, to drive the accessories when the engine is stopped, and/or to the engine crankshaft to re-start the engine. In another embodiment of the invention, the accessory drive is isolated from the engine crankshaft and is instead driven by a drive motor on the accessory drive while the engine crankshaft is connected to a starter motor and/or generator which can be energized to re-start the engine. |
