Abstract:

A mobile testing environment is adapted for detecting drive line system imbalances in an automotive vehicle and includes an enclosed trailer for providing insulation from ambient weather, temperature and noise. The trailer also has a hitch for attachment to a towing vehicle for transport. An angular position and speed sensor is adapted to generate a signal responsive to speed and angular position of a drive shaft. Vibration sensors are adapted to detect drive line vibration and generate a signal responsive thereto. A signal analyzer is adapted to receive signals generated by the angular position and speed sensor and the vibration sensors 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 the signal analyzer.
