Abstract
A belt integrated starter generator may selectively drive accessory components while an engine is off. The belt integrated starter generator may also selectively drive a crankshaft of the engine. Clutches are used to access rotational power from the belt.
Claims7
An automotive accessory component power system comprising:
- a belt;
- first, second and third clutches;
- an engine including a crankshaft adapted to be selectively mechanically coupled with the belt via the first clutch;
- an electric motor adapted to be selectively mechanically coupled with the belt via the second clutch;
- and
- a mechanically driven accessory component adapted to be selectively mechanically coupled with the belt via the third clutch.
A method for powering a mechanically driven accessory component of an automotive accessory power system including a belt, first, second and third clutches, an engine having a crankshaft adapted to be selectively mechanically coupled with the belt via the first clutch, an electric motor adapted to be selectively mechanically coupled with the belt via the second clutch, and a mechanically driven accessory component adapted to be selectively mechanically coupled with the belt via the third clutch, the method comprising:
- mechanically de-coupling the crankshaft from the belt via the first clutch;
- mechanically coupling the electric motor to the belt via the second clutch;
- mechanically coupling the accessory component to the belt via the third clutch;
- and
- providing mechanical power from the electric motor to the accessory component via the belt.
