ABSTRACT:
An apparatus for detecting drive line system imbalances in an automotive vehicle includes an angular position and speed sensor located at a preselected position spaced from, but associated with the drive shaft in non-contacting relationship therewith, the sensor generates a signal responsive to the speed and angular position of the drive shaft relative to the preselected reference point. The apparatus also includes at least one vibration sensor located at a preselected position, spaced from, but associated with, the drive line in non-contacting relationship therewith. The vibration sensor detects the drive line vibration and generates a signal responsive thereto. A signal analyzer receives the signals generated by the angular position and speed sensor as well as the vibration sensor and calculates any imbalance in the drive line system and presents counterweight and position parameters for correcting any system imbalance.
