  • Patent number: 12332136
    Abstract: 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.

  • Publication number: 20250172457
    Abstract: A method is provided for detecting vibrational anomalies of a vehicle using a plurality of devices that are removably attachable to the vehicle. One of the devices is removably attachable to a wheel assembly and includes an IMU configured to remotely collect data. At least one of the other devices is not attached to any of the wheel assemblies. Acceleration data is collected from the device that is removably attachable to the wheel assembly. Vibrational data is collected from at least one of the other devices that are not attached to any of the wheel assemblies. The acceleration data is analyzed from the device that is removably attachable to the wheel assembly to determine whether a vibrational anomaly exists in the wheel assembly. The vibrational data from the at least one of the other devices that are not attached to any of the wheel assemblies is analyzed to determine whether a vibrational anomaly exists.

  • Patent number: 12181368
    Abstract: 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.

  • Patent number: 11988573
    Abstract: 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.
