Abstract: 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.

Abstract: 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.

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.

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.

Abstract: A method and apparatus for enabling a vehicle wheel alignment measurement system to compensate one or more vehicle wheel alignment angles or vehicle body measurements acquired from a vehicle for changes associated with adjustments in the elevation of vertically movable runways of an automotive vehicle lift supporting the vehicle. An initial set of pose measurements are acquired with the movable runways at a stable first elevation. Following an elevation change to the movable runways, a second set of pose measurements are acquired with the movable runways at a second stable elevation. One or more compensation factors used to compensate vehicle wheel alignment angles or vehicle body measurements for changes in the automotive vehicle lift configuration are determined by a comparison of the initial and second sets of pose measurements.
