  • Patent number: 11926221
    Abstract: A method for controlling transient operation of a variable flux machine (VFM) includes, during a shunt angle transition, receiving a commanded and measured shunt angle when operating in a predetermined operating region, e.g., maximum torque per ampere or field weakening. The method includes calculating d-axis and q-axis delta current terms (?Id and ?Iq) required to maintain an output torque level of the VFM through a duration of the shunt angle transition, then applying the required ?Id and ?Id terms as feed-forward terms to adjust a d-axis current (Id) term and a q-axis current (Iq) term from a respective lookup table. In this manner the controller maintains the output torque level of the VFM during the shunt angle transition. An electric powertrain includes the VFM, a TPIM, and the controller. A PM machine may be controlled by substituting temperature for shunt angle.

  • Publication number: 20240077607
    Abstract: A method, system and vehicle that repetitively correct angle offsets in a synthetic aperture radar image of a vehicle while the vehicle is in motion by utilizing a radar system and a camera to determine accurate velocity of a measured object by matching angles of the object in the SAR image with angles of the object in the camera image, thereby reducing angle offsets of objects in the SAR image. The method includes obtaining an SAR image of another vehicle via a radar unit of the vehicle, obtaining a camera image of the other vehicle via a camera unit of the vehicle, determining an association between at least one object in the SAR image and a corresponding at least one object in the camera image, correcting a velocity estimation of the vehicle based on the determined association, and adjusting the SAR image based on the corrected velocity estimation.

  • Publication number: 20240079611
    Abstract: Presented are systems for manufacturing membrane electrode assemblies for fuel cells, control logic for operating such systems, methods for making such MEAs, and fuel cell systems employing such MEAs. A method of manufacturing a membrane electrode assembly (MEA) for a fuel cell system includes receiving a standalone membrane (SAM) with a semipermeable proton-exchange membrane having opposing first and second faces and a backing layer attached to the first face. A SAM may be characterized by a lack of cathode and anode electrodes upon receipt of the membrane. The second face of the SAM is placed across a vacuum plate; the vacuum plate applies a predefined vacuum pressure to the SAM. While vacuum pressure is being applied to the SAM by the vacuum plate, the backing layer is removed from the SAM. A subgasket is then attached to the first face of the SAM after the backing layer is removed.

  • Publication number: 20240075826
    Abstract: The concepts described herein provide a system and associated charging connector that is capable of offloading electric power stored in a rechargeable energy storage system (RESS) of an electrified vehicle to supply electric power to a stationary system, e.g., a residential dwelling or a business site, upon occurrence of a power outage in an electric power grid that supplies electric power to the stationary system. This includes the charging connector being capable of offloading electric power under conditions in which the RESS of the electrified vehicle is initially disconnected from the charging connector when the power outage occurs. This concept enables an electrified vehicle to supply electric power to a stationary system when connecting after a delay period subsequent to the power outage.
