Patent number: 12091001Abstract: The present technology is directed to training and the use of a machine learning model to measure the safety of an autonomous vehicle (AV) driving in simulation. An AV management system can run a simulation of an AV autonomously piloting itself and collect simulation driving data. Further, the AV management system can parse the simulation driving data into kinematic and semantic environmental features and output a simulation safety score of the simulation based on the kinematic and semantic environmental features. The simulation safety score indicates a probability of a safety critical event such as a collision or a near-miss between the AV and the at least one simulated object in the simulation.Type: GrantFiled: April 20, 2022Date of Patent: September 17, 2024Assignee: GM Cruise Holdings LLCInventors: Geoffrey Louis Chi-Johnston, Laura Athena Freeman, Christopher Brian Roland, Daniel Tien, Feng Tian, Seunghyun Min, Lei Huang, Diego Plascencia-Vega

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.
