Starter-generator
A vehicle includes a starter-generator. According to some embodiments, one of at least two operator activated input mechanisms may be selected for starting the starter-generator. According to some methods of operation, the starter-generator can be used to pre-set pistons of the engine.
1. A method for operating a vehicle, the method comprising:
selecting one of at least two input means for sending a starting signal to a starter-generator; and
sending the starting signal via the selected input means to a control unit, to energize a stator of the starter-generator.
2. The method of claim 1 , wherein one of the at least two input means includes a keyed ignition.
3. The method of claim 1 , wherein one of the at least two input means includes a throttle actuator.
4. The method of claim 3 , wherein release of the throttle actuator stops the starter-generator.
5. The method of claim 1 , wherein selecting one of at least two input means is accomplished via a starter-generator selection switch mounted on a steering member of the vehicle.
6. A vehicle including an engine and a starter-generator, the vehicle comprising:
an electronic control unit operatively coupled to the starter-generator;
at least two operator activated input means, each input means configured to send a starting signal to the electronic control unit for starting the starter-generator; and
a starter-generator selection switch for selecting one of the at least two operator activated input means.
7. The vehicle of claim 6 , wherein one of the at least two operator activated input means comprises a throttle actuator.
8. The vehicle of claim 7 , wherein release of the throttle actuator stops the starter-generator.
9. The vehicle of claim 6 , wherein one of the at least two operator activated input means comprises a keyed ignition.
10. The vehicle of claim 6 , further comprising a steering member for steering the vehicle and wherein the starter generator selection switch is mounted on the steering member.
11. The vehicle of claim 6 , further comprising a seat and wherein the electronic control unit is disposed beneath the seat.
12. The vehicle of claim 6 , wherein the starter-generator comprises an assembly, the assembly comprising:
a stator cover mounted to a crank case of the engine;
a stator including a plurality of coils, the stator disposed within the cover and mounted on an inside surface of the cover; and
a magneto flywheel disposed within the cover in proximity to the crank case and directly coupled to a crank shaft of the engine, the crank shaft extending out from the crank case; the flywheel including a disk, positioned between the crank case and the stator, and an annular wall extending axially away from a perimeter of the disk, in a direction away from the crank case, the annular wall including a magnetized inner surface surrounding the stator.
13. The vehicle of claim 6 , wherein the vehicle is selected from the group consisting of all-terrain vehicles, three-wheelers, go-carts, dune buggies, utility vehicles, snowmobiles, personal watercraft, boats with outboard motors, boats with inboard motors, scooters, and motorcycles.
