Method and apparatus for transferring power between a flywheel and a vehicle
First Claim
1. A vehicle driveline, comprising:
- a power source;
a clutch drivingly engaged with the power source;
a transmission drivingly engaged with the clutch;
a power transmission device drivingly engaged with one of the power source, the clutch, and the transmission;
a controller in communication with the power transmission device; and
a flywheel drivingly engaged with the power transmission device, wherein the power transmission device facilitates a transfer of energy from the flywheel to one of the clutch and the transmission and the power transmission device facilitates a transfer of energy from one of the power source, the clutch, and the transmission to the flywheel, the controller directing the transfer of energy to and from the flywheel based on at least one of a state of charge of the flywheel, a power requirement of the vehicle driveline, and a state of operation of the power source.

Abstract
A vehicle driveline and a method for transferring energy from a flywheel is provided. The vehicle driveline includes a power source, a clutch drivingly engaged with the power source, a transmission drivingly engaged with the clutch, a power transmission device drivingly engaged with one of the power source, the clutch, and the transmission, a controller in communication with the power transmission device, and a flywheel drivingly engaged with the power transmission device. The power transmission device facilitates a transfer of energy from the flywheel to one of the clutch and the transmission. The power transmission device also facilitates a transfer of energy from one of the power source, the clutch, and the transmission to the flywheel. The controller directs the transfer of energy to and from the flywheel.
