    Abstract: A communication module is configured to obtain, from a first computing device associated with an energy receiver, an energy request. The energy request includes a location of the energy receiver and an amount of energy requested. A selection module is configured to generate a list of energy sources available to satisfy the energy request. The communication module is further configured to: transmit the list of energy sources to the first computing device for display; receive, from the first computing device, a selection of one energy source from the list of energy sources; and transmit, to the first computing device and a second computing device associated with the selected one energy source, a location at which the energy request is to be fulfilled. An energy transfer module is configured to selectively enable an electrical energy transfer from the selected one energy source to the energy receiver.

    Abstract: A method of controlling a level of fluid in a main sump of a transmission includes opening an auxiliary reservoir with a first valve when fluid temperature in the main sump is at or below the predetermined temperature. The first valve is opened to increase the level of fluid in the main sump to at least a predetermined height so that transmission rotating components contact the fluid and generate splash lubrication. When the transmission is transmitting torque and the fluid is above the predetermined temperature, the level of fluid in the main sump is maintained below a predetermined height with closed first valve, such that the rotating components do not contact the fluid inside the main sump. A fluid pump alone is sufficient to lubricate the rotating components above the predetermined temperature and sufficient to lubricate the rotating components at or below the predetermined temperature only with splash lubrication.

    Abstract: A brake mechanism includes a clutch unit and a disc. The clutch unit includes a first and second engagement mechanism. Each engagement mechanism presents at least one tooth. The disc defines at least one slot. Each engagement mechanism is movable relative to the disc between a disengaged position and an engaged position. The tooth of the first engagement mechanism is configured to engage the slot of the disc when in the engaged position to cease rotation of the disc in a first direction of rotation. The tooth of the second engagement mechanism is configured to engage the slot of the disc when in the engaged position to cease rotation of the disc in a second direction of rotation, opposite the first direction of rotation. The disc is configured to rotate about an axis of rotation, relative to the clutch unit, when each engagement mechanism is in the disengaged position.

    Abstract: A vehicle system is described that includes a multi-phase rotary electric motor rotatably coupled via a rotatable member to an air-conditioning compressor, and a remotely located rechargeable energy storage system (RESS). The RESS includes a first power inverter that is electrically coupled to the multi-phase rotary electric motor via a plurality of electric power cables, a second power inverter that is electrically coupled to a second electric machine, a DC power source, and a chiller. A controller is in communication with and controllably coupled to the first power inverter and the second power inverter. The controller is operative to control the first power inverter to operate the multi-phase rotary electric motor in an open-loop control scheme.

    Abstract: A permanent magnet electric machine (PM machine) for a vehicle or other system includes a rotor assembly, fixed permanent magnets, a stator, an actuator, and one or more repositionable/moveable flux-shunting elements. The flux-shunting element is repositioned to control flux at specific operating points of the PM machine. The rotor assembly has a rotor coaxially surrounding and coupled to a rotor shaft. The permanent magnets are mounted to or in the rotor, and the moveable flux-shunting element is positioned between the rotor shaft and a respective one of the permanent magnets. Inboard and outboard ends of each respective permanent magnet may be oriented toward the rotor shaft and stator, respectively. The actuator selectively positions the moveable flux-shunting element at one or more operating points of the PM machine to vary reluctance in a magnetic circuit formed by the stator and rotor assembly.

    Abstract: A powertrain system for a vehicle is described, and includes an internal combustion engine that is selectively coupled to a driveline. The engine is configured to operate in a coasting mode, wherein the coasting mode includes operating the powertrain system with the engine in an OFF state and decoupled from the driveline. Devices are configured to monitor an output torque request, vehicle speed, and vehicle operating conditions. An executable instruction set monitors the vehicle speed and the output torque request. The engine is controlled to operate in the coasting mode when the output torque request is within the predetermined torque region and the vehicle speed is greater than a minimum speed threshold. The engine is controlled to discontinue operating in the coasting mode in response to the output torque request being outside the torque region of the vehicle speed being less than a minimum speed threshold.
