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.
