Abstract

Presented are intelligent vehicle systems for thermal event mitigation during vehicle towing, methods for making/using such systems, and vehicles equipped with such intelligent control systems. A method of operating a host vehicle includes a resident or remote vehicle controller verifying the host vehicle is an incapacitated state. Responsive to the incapacitation of the host vehicle, the controller detects the host vehicle being towed by a tow vehicle and identifies a wireless-enabled portable computing device (PCD) within a predefined range of the host vehicle. Responsive to the host vehicle being towed, the controller determines if the wireless-enabled PCD is on the tow vehicle while towing the host vehicle. Upon detection of a thermal event in at least one battery cell in the host vehicle's battery system while the host vehicle is being towed, the controller responsively commands a resident vehicle subsystem to execute a control operation to mitigate the thermal event.

A computer-implemented method for aligning a sensor to reference coordinate system includes initiating a plurality of threads, each thread executes simultaneously and independent of each other. A first thread parses data received from the sensor and stores the parsed data in a data buffer. A second thread computes an alignment transformation using the parsed data to determine alignment between the sensor and the reference coordinate system. The computing includes checking that the data buffer contains at least predetermined amount of data. If at least the predetermined amount of data exists, an intermediate result is computed using the parsed data in the data buffer; otherwise, the second thread waits for the first thread to add more data to the data buffer. The second thread outputs the intermediate result into the data buffer. A third thread outputs the alignment transformation, in response to completion of alignment computations.

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.
