    Abstract: A vehicle service or inspection system including a load roller for applying a radial load to a vehicle wheel assembly consisting of a tire mounted to a rim, with at least one sensor for acquiring measurements of acoustical energy generated by the wheel assembly during loaded rotational movement. The vehicle service or inspection system is configured with a programmed processor to evaluate the acquired measurements to provide a measure of tire road noise, identification of tire defects, and/or identification of sources of noise, vibrations, or acoustical energy on the tire surface such as tire flat spots, cupping, bubbles, embedded foreign objects, or other defects. The processor is further configured with software instructions to utilize the acquired measurements to provide a consumer with a figure of merit associated with the acoustics of the tire undergoing testing.

    Abstract: A vehicle ADAS target or fixture is configured with an Inertial Measurement Unit (IMU) consisting of a combination of accelerometers and gyroscopes capable of estimating a relative position and orientation within the spatial volume of the vehicle service area by tracking changes in acceleration and rotation. A controller monitors movement of the IMU relative to an established reference location, generating output utilized by a vehicle service system to guide a technician to position and orient the vehicle ADAS target or fixture at a selected location within the vehicle service area required to conduct a vehicle ADAS service procedure.

    Abstract: A vehicle service system including a set of cameras and a processing system configured to access a database of vehicle-specific information, which includes data identifying vehicle-specific targets and/or service fixtures. The processing system is configured with a user interface to convey instructions to an operator, including the identification of vehicle-specific targets and/or service fixtures required to carry out a selected vehicle service. The processing system subsequently evaluates images acquired from the set of cameras to identify features present within the images, including placed vehicle-specific targets, from which identification of, and verification of correctly selected, vehicle-specific targets is made.

    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.
