Patent number: 11645880Abstract: A controller processes data from one or more sensors of a subsystem of a vehicle. The processing includes smoothing the data and calculating a mean of the data. The controller identifies a transition point in the processed data where a moving average of the data is less than the mean by a predetermined amount indicating a trend. The controller selects a segment of the processed data subsequent to the transition point, detects the trend in the segment using regression, and extrapolates the detected trend to reach a predetermined fault threshold. The controller predicts a failure of the subsystem based on a slope of the extrapolated trend and provides an indication of the prediction based on the slope to schedule a service for the subsystem.Type: GrantFiled: January 14, 2021Date of Patent: May 9, 2023Assignee: GM GLOBAL TECHNOLOGY OPERATIONS LLCInventors: Xinyu Du, Zhongyu Yang, Joshua J.
