Publication number: 20230401899Abstract: A method, apparatus, system for managing a maintenance for a component in a vehicle. Sensor data is received for the vehicle. Target parameters are predicted using behavior machine learning models trained using first training data to predict the target parameters for a normal behavior of the component operating in a tolerance, wherein the target parameters characterize behavior of the component. Prediction metrics are determined from predicted values for the target parameters predicted by behavior machine learning models and actual values for the target parameters. Whether the component will fall out of the tolerance after a time period is predicted using the prediction metrics and a maintenance machine learning model trained using second training data to predict whether the maintenance is needed for the component, wherein the second training data comprises historical prediction metrics determined for the target parameters.Type: ApplicationFiled: June 8, 2022Publication date: December 14, 2023Inventors: Changzhou Wang, Darren Puigh, Darren Brian Macer, Jun Yuan, Mark Mazarek, Lesley Quach

Publication number: 20230298391Abstract: A computing device predicts whether a given component currently installed on a vehicle should be removed from the vehicle, and if so, identifies the location of the given component on the vehicle. The prediction is based on a prediction model that is generated by the computing device using maintenance data associated with the maintenance of components currently installed on, and/or previously removed from, the vehicle, as well as removal data associated with the previous removal of the same type of components from the vehicle. Information associated with the prediction is then output graphically to a display so that an operator can effect the removal of the component.Type: ApplicationFiled: January 31, 2022Publication date: September 21, 2023Inventor: Changzhou Wang

Publication number: 20230245507Abstract: A phased approach to predicting whether a component currently installed on a vehicle should be removed is provided. In a first phase, a prediction model is created using historical data and sample values that are associated with a vehicle component previously removed from the vehicle. In a second phase, the output of the prediction model is used to predict whether the selected vehicle component currently installed on the vehicle should be removed. Based on the prediction, a graphical user interface (GUI) is generated for output to a user. The GUI visually indicates the vehicle component predicted to be removed and provides a recommendation for addressing the predicted removal of the component.Type: ApplicationFiled: January 31, 2022Publication date: August 3, 2023Inventor: Changzhou Wang
