  • 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: 11745271
    Abstract: An adjustable hub adapter for coupling an on-car brake lathe to a wheel hub. An annular support frame coaxially carries an axially bored and threaded central mounting hub with a set of equidistantly spaced spokes. A lug bolt receiver is associated with each spoke, and consists of a receiving tube, a lever arm pivotally coupled to the spoke at a pivot bolt in proximity to the annular support frame. An engagement pin on each lever arm is captured within a synchronizing ring carried on the annular support frame. The rotational movement of any lug bolt receiver about an axis of the pivot bolt imparts rotational movement to the synchronizing ring, and in turn, causes each remaining bolt receiver to rotate about an associated pivot bolt axis, maintaining the lug bolt receivers in a synchronized and symmetric radial displacement from the central mounting hub.

  • Patent number: 11721140
    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.

  • Patent number: 11704830
    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.

  • Patent number: 11614380
    Abstract: A drive-through vehicle inspection system acquiring information from engraved markings on the tire sidewalls of a moving vehicle. Optical imaging sensors disposed on opposite sides of the vehicle acquire images of the sidewall surfaces for each passing wheel assembly. The acquired images are evaluated by a processing system configured to identify, within the acquired images, visible markings engraved into the tire sidewall surfaces which include at first portion having a first optical reflectivity, and a second portion having a second optical reflectivity which is different from the first optical reflectivity. Each identified marking is decoded to retrieve data stored therein, representative of the tire, wheel assembly, and/or associated vehicle onto which the wheel assembly is installed. The retrieved data is incorporated into an inspection report and/or utilized by the vehicle inspection system to access vehicle-specific information contained within an indexed database.
