  • Patent number: 11971250
    Abstract: A vehicle service system incorporating a pair of gimbal-mounted optical projection systems enables an operator to selectively orient each optical emitter of the optical projection system to illuminate a location on a vehicle surface in proximity to the system. Signals indicative of an orientation of each optical emitter about three-axes of rotation are received at a controller programmed with software instructions to utilize the received signals, together with known locations for the systems, to calculate a three-dimensional coordinate for the illuminated location within an established frame of reference. The controller is further programmed to utilize the calculated three-dimensional coordinate of the illuminated location as an origin point for determining one or more placement locations within the established frame of reference for ADAS sensor calibration or alignment targets.

  • Patent number: 11538188
    Abstract: A method and apparatus for calibrating a projection axis orientation for an optical projector associated with a vehicle inspection or service system so as to enable projection of indicia onto selected spatial locations within a vehicle service area. Projector axis orientations required for the projection of visible indicia onto reference targets disposed at determinable locations within a common coordinate system of the vehicle service area are utilized to establish a relationship utilized to mathematically transform between selected spatial coordinate locations for projected indicia and corresponding orientations of the projection axis, facilitating projection of the visible indicia to additional spatial coordinate locations within the common coordinate system.

  • Publication number: 20210148702
    Abstract: A heavy-duty vehicle measurement system utilizing displacement sensor modules disposed in housings on opposite sides of a vehicle inspection lane to acquire a set of displacement measurements associated with a moving heavy-duty vehicle. Displacement data along one or more measurement axes is acquired independently by each of the displacement sensor module to measure corresponding distances between the sensor module and points on a surface of the passing heavy-duty. A processing system is configured to receive and evaluate the set of displacement measurements, together with known parameters of the measurement system, to identify heavy-duty vehicle features, such as configuration, body panels, wheel assemblies, and tire surfaces, and to calculate heavy-duty vehicle parameters such as velocity, wheel rim or tire dimensions, axle relative orientations (scrub angles) and wheel assembly spatial orientations.

  • Patent number: 10444010
    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.

  • Patent number: 10311835
    Abstract: A vehicle service system configured to acquire images of a three-dimensional region of a vehicle wheel assembly tire tread surface. The vehicle service system is configured to process the acquired images to produce a collection of data points corresponding to the spatial position of surface points in the region from which tire tread wear characteristics are identified. The acquired images are further utilized to provide both a graphical and a numerical display to an operator, with the numerical display linked to specifically annotated or indexed points or windows within the graphical display, thereby enabling an operator to quickly identify specific focus points or regions on the tire surface which have been measured at the numerically identified tread depths.
