    Abstract: A vehicle measurement station utilizing one or more displacement sensors disposed on each opposite side of an inspection region of a vehicle inspection lane to acquire displacement measurement data along associated measurement axes. At least a portion of the displacement measurement data is associated with the outermost wheel assemblies on an axle of a moving vehicle passing through the inspection region, and utilized to determine one or more vehicle characteristics, such as an axle total toe condition.

    Abstract: A method for detecting the occurrence of deviations from level, straight-line rolling movement of a wheel assembly across a supporting surface during a rolling compensation procedure associated with a vehicle wheel alignment measurement or inspection system by identifying changes in measurements or calculated parameters associated with the wheel assembly which would be unchanged during an ideal level and straight-line rolling movement. Identified changes in the measurements or calculated parameters are evaluated to either warn an operator of the occurrence of a deviation, or to generate a correction factor to account for at least a portion of an effect which the deviations introduce into compensation calculations or subsequent wheel alignment measurements or service procedures.

    Abstract: A method for characterizing the surface over which a vehicle is to be rolled during a rolling compensation procedure. A set of wheel alignment angle sensors are mounted to the rearmost fixed axle of a vehicle which is then backed onto the floor surface to be characterized, and rolled in reverse over the region of the floor surface generally traversed during a rolling compensation procedure. As the vehicle is rolled in reverse, a pair of wheel alignment angle sensors temporarily positioned at selected points on the floor surface measure a distance to the wheel-mounted alignment angle sensors, which in turn, are acquiring camber angle measurements. The resulting set of measurements is stored in an accessible data storage device, characterizing the camber altering contours of a path across the floor surface.

    Abstract: A vehicle ADAS target or fixture is configured with an Inertial Measurement Unit (IMU) consisting of a combination of accelerometers and gyroscopes capable of estimating a relative position and orientation within the spatial volume of the vehicle service area by tracking changes in acceleration and rotation. A controller monitors movement of the IMU relative to an established reference location, generating output utilized by a vehicle service system to guide a technician to position and orient the vehicle ADAS target or fixture at a selected location within the vehicle service area required to conduct a vehicle ADAS service procedure.
