摘要： A machine-vision vehicle wheel alignment measurement system configured with at least one optical sensor to acquire images of optical targets disposed within an operative field of view. The system further includes a processing system configured with software instructions to determine relative spatial positions and orientations of one or more optical targets visible within images acquired by the optical sensor. The processing system is further configured with software instructions to automatically identify an axle count and axle configuration for a vehicle undergoing an alignment inspection or service using the determined relative spatial positions and orientations of the visible optical targets.

摘要： A tire changer machine, and method of operation, configured with a tire-engaging wheel clamp assembly to secure a wheel assembly consisting of a wheel rim and tire mounted thereon to a drive assembly, and for demounting of the tire from the wheel rim. Upon dismounting of the tire from the wheel rim, a recessed surface and annular flange of the tire-engaging wheel clamp assembly is configured to catch and retain a rim or bead of the demounted tire, restricting movement of the tire upon dismounting from the wheel rim, until retrieved by an operator.

摘要： A machine-vision vehicle service system, and methods of operation, incorporating at least one at least one camera and an optical projector for guiding placement of vehicle service components relative to a vehicle undergoing service. The camera and optical projector are operatively coupled to a processing system configured with software instructions to selectively control a projection axis orientation for the optical projector to enable projection of visible indicia onto various surfaces visible within the field of view of the camera.

摘要： An on-car brake lathe is provided with a runout compensation system configured to monitor the rotational position of a pair of slant discs within an aligning joint of the on-car brake lathe. The system monitors the amount of runout present between the rotating components of the on-car brake lathe and the wheel hub to which the on-car brake lathe is secured, and calculates a relative rotational position for each slant disc within the aligning joint required to impart a necessary adjustment in the wheel coupling rotational axis to align the on-car brake lathe with the rotational axis of the wheel hub. An adjustment mechanism within the aligning joint is configured to rotationally drive each slant disc to the calculated relative rotational positions with a minimum amount of rotational movement based on the current relative rotational position of each slant disc and the required calculated relative rotational positions.

摘要： 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.

摘要： A vehicle service system for interaction with the on-board electronic systems of a vehicle utilizing a cloud-based vehicle diagnostic system which is configured on-demand for the vehicle undergoing a service procedure. The vehicle service system includes a local processing system in communication with the vehicle and with a cloud-based vehicle diagnostic application service configured to establish an on-demand virtual processing system running a vehicle-specific diagnostic software application. The vehicle-specific diagnostic software application communicates with the vehicle undergoing service to present a service technician with diagnostic results within a graphical user interface of the local processing system. Upon completion of the vehicle service, the remote cloud-based vehicle diagnostic application service terminates the virtual processing system and vehicle-specific diagnostic software application, freeing cloud-based resources for subsequent uses.

摘要： A system and method for vehicle technician communication utilizing a local vehicle service system operatively coupled to a remote vehicle service system via a network connection. The system enables bi-directional communication between the local service technician and a service specialist associated with the remote vehicle service system by configuring the local vehicle service system with software instructions and hardware to provide a communication interface, such as a software app, graphical user interface, or teleconference functionality. Using the communication interface, the service specialist can: (1) guide the local technician through the initial process of establishing a connection between the vehicle undergoing service or inspection and the remote vehicle service system; (2) direct necessary actions during a diagnostic analysis of the vehicle, such as turning on the vehicle's engine, turning a steering wheel, etc.; and (3) convey results of the vehicle diagnostic analysis in verbal, written, or visual form.

摘要： A vehicle service system incorporating a set of imaging sensors disposed in an inspection lane through which a vehicle is driven. A first imaging sensor is disposed with a field of view aligned to observe leading surfaces on an approaching vehicle, while a second imaging sensor is disposed with a field of view aligned to observe trailing surfaces of a departing vehicle. A processor is configured with software instructions to capture a set of images from the first imaging sensor as the vehicle approaches, and a set of images from the second imaging sensor as the vehicle departs. The processor evaluates the acquired images from the first and second imaging sensors according to a set of rules to identify images in which a license plate is present on an observed surface of the vehicle, and to extract license plate information from at least one of the identified images.

摘要： 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.

摘要： A tire changer machine, and method of operation, configured to enable a single operator to carry out tire change procedures for a set of wheel assemblies by interleaving wheel assembly balancing procedures on a wheel balancer machine with an automated tire demount process carried out under direction of a control system of the tire changer without continuous operator input or supervision.
