    Abstract: A support structure having a vertical element supporting a set of cameras associated with a vehicle measurement or inspection system together with at least one target structure required for realignment or recalibration of onboard vehicle safety system sensors. A camera crossbeam carried by the support structure locates the set of cameras as required to view a vehicle undergoing measurement or inspection. The target structure is affixed to the vertical element of the support structure, at an elevation suitable for observation by at least one vehicle onboard sensors during a realignment or recalibration procedure. A set of rollers facilitates positioning of the target structure on a supporting floor surface during a realignment or recalibration procedure.

    Abstract: A method and apparatus for calibrating laser displacement sensors within a vehicle inspection system. A calibration target structure is positioned within an operative field of view for the laser displacement sensor, providing one or more optical targets onto which illuminating laser beams from the laser displacement sensor are projected. Displacement measurements are acquired with the optical targets disposed at a plurality of positions within the field of view. The resulting displacement measurements, together with known position information for the optical targets, are utilized to calibrate an associated imaging sensor such that the displacement measurements associated with each illuminating laser beam and known positional information agree to within a desired tolerance throughout the operative field of view for the laser displacement sensor.

    Abstract: A turn plate assembly for support of the steered wheels of a vehicle on a precision planar surface. The assembly includes an approach plate establishing a planar surface to within an established measurement tolerance. The approach plate is coupled to a base plate underlying a bearing assembly consisting of a plurality of ball bearings retained between the base plate and an underside of a rotating support disc. An upper surface of the rotating support disc is coplanar with an upper surface of the approach plate. Resting on the upper surface of the rotating support surface, a translational surface or mat is temporarily secured in place by magnetic adhesion. During use, translational forces exerted on the translation surface or mat by a vehicle wheel assembly may overcome the magnetic adhesion, enabling the translational surface or mat to translate relative to the underlying rotating support disc.

    Abstract: A calibration fixture for use during a calibration procedure of a machine vision vehicle wheel alignment system. The calibration fixture consists of a pair of support legs, and a rotating transverse bar supported within an outer support tube secured between the support legs. The rotating transverse bar is supported within the outer support tube by a pair of annular bearings adjacent each end of the outer support tube, and is isolated from external influences which may result in deflection or distortion. A hub for receiving a sensor or optical target is secured to each end of the rotating transverse bar, such that optical targets mounted to each hub are maintained in axial alignment at opposite ends of the rotating transverse bar.

    Abstract: A procedure for measuring and adjusting an alignment of each axle of a trailer or semi-trailer while the trailer or semi-trailer is coupled to a tow vehicle by a hitch, tow bar, kingpin, or fifth wheel hitch. Measurements of the alignment of each axle of the trailer or semi-trailer are acquired from wheel-mounted sensor means utilizing either directly or indirectly a reference line of the trailer and an established reference point on the tow vehicle. A thrust angle of a first trailer or semi-trailer axle is referenced directly to the established reference line, while scrub angles associated with additional trailer or semi-trailer axles are referenced either directly or indirectly to the first trailer or semi-trailer axle, and indirectly to the established reference point. Any necessary adjustments are made to the first trailer or semi-trailer axle to bring the axle thrust angle to within a specification tolerance, and then to the scrub angle of each additional axle.

    Abstract: A method and apparatus for detecting, for wheel assemblies on opposite ends of an axle during an alignment angle measurement or inspection process, relative movement or slip between the alignment angle sensor or optical target and the wheel assembly upon which it is mounted. Changes in measurements of invariant characteristics of the solid axle or an associated wheel assembly are observed by an alignment measurement or inspection system as indications of movement or slip between at least one of the alignment angle sensors or optical targets and the associated wheel assembly. Upon detection of a change a measurement of an invariant characteristic, an operator is alerted by the alignment measurement or inspection system to the presence of movement or slip of one or both of the alignment angle sensors or optical targets associated with the wheel assemblies of the axle.

    Abstract: A vehicle wheel service system including a plurality of sensors positioned in proximity to a heavy-duty multi-axle vehicle, to measure angles associated with three or more axles of the vehicle without repositioning the mounting of the sensors after initiating a measurement procedure. Additional sensors, associated with a vehicle reference, such as the vehicle frame axis, are disposed to provide vehicle reference measurement data which is communicated to a processing system. The processing system is configured with software instructions to evaluate the measurement data and to determine various vehicle wheel alignment angle measurements and/or necessary vehicle adjustments for each axle relative to the vehicle reference or to a fixed axle having a determined relationship to the vehicle reference.
