A correlator system for automatic car wash has roller assemblies for supporting the front left and right wheels of a vehicle entering a car wash line. A set of guide rails or bars cooperate with the roller assemblies to adjust axial displacement and angular misalignment between the vehicle's front end and a conveyor track transporting the vehicle through the car wash facility. The rollers in the roller assembly rotate freely with minimal friction, axially displacing the front end of the vehicle and adjusting the angular misalignment of the front wheels. The low friction, easy-to-rotate rollers are provided with a plurality of braking elements that generate friction against the rollers, retarding their rotation when a worker steps thereon. The friction generated by the braking elements is insufficient to prevent roller rotation during alignment of the front end with the conveyor track. Injuries to car wash personnel caused by loss of balance when stepping on the rollers are virtually eliminated, and an accurate alignment of the vehicle's front end with the car wash conveyor track is reliably achieved.

The current invention is intended to be installed in revenue service railroad tracks to detect railroad cars exhibiting wheel set lateral instability. The invention utilizes an array of inductive proximity sensors mounted at regular intervals in a section of railroad track. Each proximity sensor is oriented to sense the lateral position of railroad car wheel sets. The invention employs a computer algorithm to extrapolate the trajectory from the set of proximity sensor signals for each wheel set. A second algorithm evaluates the shape of the trajectory to detect oscillating lateral motion of the wheel set. A third algorithm assesses the severity of any wheel set lateral oscillations that are detected. An additional function of the invention is to detect railroad car trucks that exhibit “tracking errors”.
