Abstract: A system and method for guiding placement of a vehicle service external fixture relative to a vehicle undergoing service or inspection. A vehicle service system support structure having at least one camera module is positioned at an initial location within a vehicle service area, and a location of the initial location within a vehicle reference frame is established from images of optical targets secured to the vehicle. The vehicle service system support structure is subsequently repositioned relative to the vehicle to a new position located outside of an external fixture placement region, while maintaining at least one of the observed optical targets within a field of view of the camera module. The new position of the vehicle service system support structure within said vehicle reference frame is determined from target images, and a placement location within the placement region for the external fixture is identified relative to the vehicle.

Abstract: A machine-vision vehicle service system, and methods of operation, incorporating at least one gimbaled sensor module configured with at least one of a camera, an optical projector, or a range finder to acquire or convey data associated with surfaces in proximity to the vehicle service system for guiding placement of vehicle service components relative to a vehicle undergoing service. The gimbaled sensor module is operatively coupled to a processing system configured with software instructions to selectively control an orientation of the gimbaled guidance system about one or more axis of rotation, enabling observation, projection of visible indicia, or displacement measurement along an associated sensor axis parallel with one of the axis of rotation during vehicle service procedures.

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 procedure for calibrating a vehicle onboard sensor 202 by facilitating the placement of a calibration fixture 110 on a floor relative to a stationary vehicle 100 using a laser emitter 102 secured to a front steerable wheel 104 of the vehicle on the same lateral side as the vehicle onboard sensor. A beam projection axis X of the laser projector is aligned at a known orientation relative to a geometric characteristic of the vehicle 100, such that the beam projection axis X is directed over a placement location P of the calibration fixture on the floor, either inherently or by guided steering of the supporting steerable wheel. A distance between the calibration fixture 110 and a reference point associated with the vehicle 100 is measured, and a current position of the calibration fixture on the floor along the beam projection axis X is adjusted as required to position the calibration fixture for calibration of the vehicle sensor 202 at a selected distance from the reference point along the beam projection axis X,

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 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.
