Publication number: 20240300517Abstract: A system for a host vehicle operating on a road surface includes a polarimetric camera, a global positioning system (“GPS”) receiver, a compass, and an electronic control unit (“ECU”). The camera collects polarimetric image data of a drive scene, including a potential driving path on the road surface. The ECU receives the polarimetric image data, estimates the Sun location using the GPS receiver and compass, and computes an ideal representation of the road surface using the Sun location. The ECU normalizes the polarimetric image data such that the road surface has a normalized representation in the drive scene, i.e., an angle of linear polarization (“AoLP”) and degree of linear polarization (“DoLP”) equal predetermined fixed values. The ECU executes a control action using the normalized representation.Type: ApplicationFiled: March 6, 2023Publication date: September 12, 2024Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Michael Baltaxe, Tzvi Philipp, Tomer Pe'er, Dan Levi

Publication number: 20240304878Abstract: Catastrophic capacity failure in Lithium Metal Battery (LMB) cells is preceded by an increase in battery resistance. At a fixed temperature, the onset of failure occurs at the same value of resistance across the cell(s). Various embodiments use this phenomenon as a prognostic for predicting when such a failure is likely to occur. In various aspects, a normalized resistance in a vehicle or other device may be detected and compensated for temperature differences. The compensated resistances, a threshold state of charge (SOC), and capacity differences may be used to predict capacity failure in remaining capacity or distance (e.g., miles), to identify failing LMB cells, and to send a prognostic alert.Type: ApplicationFiled: March 7, 2023Publication date: September 12, 2024Applicant: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Charles W.
