<p>A mobile testing environment (100) is adapted for detecting drive line system imbalances in an automotive vehicle (118) and includes an enclosed trailer (102) for providing insulation from ambient weather, temperature and noise. The trailer (102) also has a hitch (124) for attachment to a towing vehicle for transport. An angular position and speed sensor (130) is adapted to generate a signal responsive to speed and angular position of a drive shaft.Vibration sensors (132), (134), and (136) are adapted to detect drive line vibration and generate a signal responsive thereto. A signal analyzer (138) is adapted to receive signals generated by the angular position and speed sensor (130) and the vibration sensors (132), (134) and (136) to calculate any imbalance in the drive line system and present counterbalance weight and position parameters for correcting any system imbalance. The angular sensor comprises a pair of perceptron cameras adapted to send a pair of signals to signal analyzer (138).</p> |
