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.

Method and apparatus for anomaly analysis of a subsystem or component of a vehicle that experiences mechanical vibration during rotation of the subsystem or component of the vehicle

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.

An apparatus is provided for detecting vibrational anomalies of a vehicle. The apparatus includes a first device and a second device. The first device is removably attachable to a wheel assembly of the vehicle and includes an inertial measurement unit (IMU) configured to remotely collect acceleration data, and a microcontroller. The second device is also removably attachable to the vehicle, but is not attached to any of the wheel assemblies. The second device is configured to collect vibrational data. The microcontroller is configured to receive the remotely collected acceleration data and the vibrational data from the respective first and second devices, analyze the acceleration data from the first device to determine whether a vibrational anomaly exists in the wheel assembly, analyze the vibrational data from the second device to determine whether a vibrational anomaly exists, and compare the analyzed acceleration data from the first device and the analyzed vibrational data from the second device to identify a potential source of vibrational anomaly in the vehicle. When the analyzed acceleration data from the first device determines that there is negligible vibrational anomaly from the wheel assembly and the analyzed vibrational data from the second device determines the existence of a vibrational anomaly, the comparison identifies that the potential source of vibrational anomaly in the vehicle is in a part of the vehicle other than the wheel assembly.
