Publication number: 20240075935Abstract: A method for controlling a motor vehicle having an electronic control unit (ECU), includes enabling an initial set of vehicle performance limits of the motor vehicle via the ECU in response to a request signal from a computer device. The method includes detecting a current vehicle state of the motor vehicle, including one or more of a location of the motor vehicle, an occupancy state of the motor vehicle, and/or an experience level of a driver thereof, and dynamically adjusting at least one of the performance limits in response to the current vehicle state. A motor vehicle includes one or more road wheels and vehicle components connected to a vehicle body. The ECU includes non-transitory memory on which is recorded instructions for performing the method.Type: ApplicationFiled: September 6, 2022Publication date: March 7, 2024Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Shuhaib Saleem, Benjamin Tran, Zaid Shaheri, Russell A.

Publication number: 20240079611Abstract: 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.Type: ApplicationFiled: September 2, 2022Publication date: March 7, 2024Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Ruichun Jiang, Michael Sweet, Kathryn L. Stevick, Burl B. Keel, Jackie Mara
