|20130192915||APPARATUS FOR BRAKING FLYWHEEL SYSTEMS AND METHOD FOR DISSIPATING ENERGY STORED THEREIN - A flywheel energy storage assembly and a method for dissipating energy stored in a flywheel assembly is provided. The flywheel energy storage assembly includes a flywheel rotatably disposed in a flywheel housing, a fluid source, a braking actuator in fluid communication with the fluid source and an interior of the flywheel housing, a sensor, and a controller in communication with the sensor and the braking actuator. In response to a stimulus detected by the sensor, the controller directs the braking actuator to facilitate fluid communication between the fluid source and the interior of the flywheel housing to dissipate energy stored in the flywheel energy storage assembly.||08-01-2013|
|20130192413||METHOD AND APPARATUS FOR TRANSFERRING POWER BETWEEN A FLYWHEEL AND A VEHICLE - 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.||08-01-2013|
|20130150210||SHIFTING PROCEDURE FOR POWERSPLIT SYSTEMS - A method for shifting a transmission capable of operating in a hydrostatic power transmission mode or a blended hydrostatic and mechanical power transmission mode is provided. The transmission includes a mechanical portion and a hydraulic portion. The method comprises the steps of placing the transmission in the hydrostatic power transmission mode, reducing an amount of engagement of a primary clutch, adjusting a rotational speed of the hydraulic portion, increasing an amount of engagement of a secondary clutch, and engaging the secondary clutch and disengaging the primary clutch. The method for shifting the transmission minimizes torque interruption, increases a fuel efficiency of a vehicle, and increases a range of operating speeds of the vehicle the transmission is incorporated in||06-13-2013|
|20130090210||DEVICE AND METHOD FOR SYNCHRONIZING A FLYWHEEL WITH A DRIVETRAIN - A vehicle driveline and a method for synchronizing a flywheel and the vehicle driveline are provided. The vehicle driveline includes a power source, a primary clutch drivingly engaged with the power source, a primary transmission drivingly engaged with the primary clutch, a secondary transmission drivingly engaged with one of a portion of the primary clutch and an input of the primary transmission, a controller in communication with the secondary transmission, and a flywheel drivingly engaged with the secondary transmission. The vehicle driveline facilitates a 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.||04-11-2013|
|20120240564||ACCUMULATOR ASSISTED HYDROSTATIC DRIVELINE AND OPTIMIZATION METHOD THEREOF - A hydrostatic driveline for a vehicle, a method for minimizing a fuel consumption rate of the vehicle, and a method for tracking an optimal state of charge function for a hydrostatic accumulator are provided. The driveline includes a power source, a drive axle, a first fluid accumulator, a second fluid accumulator, an auxiliary circuit including a first pump drivingly engaged with the power source, and a drive circuit including a second pump drivingly engaged with the power source, a motor drivingly engaged with the drive axle, and a directional valve. The second pump is in fluid communication with the directional valve and the directional valve in fluid communication with the first fluid accumulator and the second fluid accumulator. The directional valve may be selectively controlled to direct fluid from the second pump and the motor to the first fluid accumulator and the second fluid accumulator.||09-27-2012|
