Anomaly analysis is performed for a subsystem or component of a vehicle that experiences mechanical vibration during rotation of the subsystem or component using a database of trends of the axis of rotation and trends of vibrational frequencies of a plurality of different subsystems or components with known anomalies, and an artificial intelligence (AI) model. In operation, a first processor triangulates a location of the axis of rotation of the subsystem or component of the vehicle at any instance of time using motion data collected from a plurality of motion measurement sensors that are attached to the subsystem or component, thereby defining locations of the axis of rotation at a plurality of successive instances of time. A second processor determines, using the AI model and the trends of the axis of rotation in the database, points of interest from the locations of the axis of rotation of the subsystem or component at the successive instances of time. The anomaly of the subsystem or component is identified using the AI model and the trends of the axis of rotation and trends of vibrational frequencies in the database, wherein the AI model uses the points of interest in its processing. One or both of a cause of the anomaly and a recommended corrective action to be taken to address the anomaly is generated using the AI model, wherein the AI model uses the identified anomaly of the subsystem or component in its processing. The AI model outputs one or both of the cause of the anomaly, and the recommended corrective action to be taken to address the anomaly.

Anomaly analysis is performed for a plurality of subsystems or components of a vehicle that experiences mechanical vibration during operation of the vehicle using a database of vibrational profiles of a plurality of different subsystems or components of the vehicle with known anomalies, and an artificial intelligence (AI) model. Vibrational data is collected of each subsystem or component at any instance of time by a plurality of motion measurement sensors. The plurality of motion measurement sensors are located in the plurality of subsystems or components. The vibrational data is processed in the AI model to create a vibrational profile for each subsystem or component. The anomaly of each subsystem or component is identified by matching, using the AI model, the vibrational profile for each subsystem or component to a profile of an anomaly in the database. The AI model outputs, using the identified anomaly of each subsystem or component, one or both of a cause of the anomaly of each subsystem or component, and a recommended corrective action to be taken to address the anomaly of each subsystem or component.

Method and apparatus for anomaly analysis of a plurality of subsystems or components of a vehicle that experiences mechanical vibration during operation of the vehicle

An apparatus is removably attached to lug nuts of a vehicle's wheel assembly for use in determining imbalance forces of the wheel assembly during motion of the vehicle. The apparatus includes a plurality of data collection devices. Each data collection device is removably attachable to one lug nut of the same wheel. Each data collection device includes a single cup-shaped object and a motion measurement sensor. The data collection object is mounted to the vehicle's wheel by fitting the cup-shaped object over the lug nut of the wheel. The motion measurement sensor measures parameters that are used for calculating the imbalance forces during motion of the vehicle. A processor receives the measured parameters from motion measurement sensors of each of the data collection devices and uses the measured parameters to identify an instantaneous center of rotation of the wheel assembly for use in determining imbalance forces of the wheel assembly of the vehicle during motion of the vehicle.
