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.

Method for detecting vibrational anomalies of a vehicle using a plurality of devices that are removably attachable to the vehicle

A method is provided for determining a magnitude of a mass to be placed on a wheel assembly using data from one or more inertial measurement units (IMU's). The one or more IMU's are mounted to a removably attachable object that is attached to a wheel of the vehicle in a manner that inhibits the object from coming off of the vehicle when the vehicle is in motion. Each of the IMU's include an accelerometer. A set of acceleration data is collected from the one or more IMU's while the vehicle is in motion. The acceleration data is applied to a predictive model to determine the magnitude of the mass.

Method for determining a magnitude of a mass to be placed on a wheel assembly using acceleration data

A method is provided for determining a location to place a mass on a wheel assembly. A first set of acceleration data is collected from a plurality of inertial measurement units (IMU's) that are mounted to a removably attachable object that is attached to a wheel of the vehicle in a manner that inhibits the object from coming off of the vehicle when the vehicle is in motion. The first set of acceleration data is collected while operating the vehicle at a first speed. The first set of acceleration data is used to determine an offset between a center of the object and a bearing center of the wheel assembly. A second set of acceleration data is collected from the plurality of inertial measurement units (IMU's). The second set of acceleration data is collected while operating the vehicle at second speed that is greater than the first speed. The second set of acceleration data and the offset determined from the first set of acceleration data is used to determine the location to place the mass on a wheel assembly with respect to the bearing center of the wheel assembly.
