  • Patent number: 8712720
    Abstract: A tire measurement system includes a computer with various memory/media elements for storing raw and transformed tire measurement data (e.g., a data set of measured radial or lateral run-out values) as well as software in the form of computer-executable instructions, which are executed by a processor to filter selected run-out values within the obtained data set that spike above adjacent measurements, identify selected ones of the filtered run-out values that lie on a convex hull surrounding the entire set of values, and perform interpolation of the identified selected ones of the run-out values that lie on the convex hull to obtain a final data set of filtered run-out measurements. Similar steps can be performed on an inverted data set to better detect sidewall deformation features such as sidewall depressions.

  • Patent number: 8645027
    Abstract: A method of adjusting the angular rolling position of the plane of a motor vehicle wheel, in which the wheel is mounted on a vehicle so that the plane of the wheel can present a static angular position and a safety angular position, the method providing for the plane of the wheel to be maintained in the static angular position when the wheel is rolling and, in case of detection of at least one critical rolling parameter, for the wheel plane to be shifted to a safety angular position for a predetermined time period before the plane of the wheel is returned to the static angular position. A wheel mounting of a motor vehicle in which the method can be implemented is provided.

  • Publication number: 20130162265
    Abstract: A tire testing apparatus and method for detecting anomalies in the surface of a tire is disclosed. A high voltage probe having a conductive spring electrode is placed adjacent a portion of a tire surface such that the conductive spring electrode is compressed against the surface of the tire. Relative motion is imparted between the high voltage probe and the surface of the tire. An electrical discharge occurs between the high voltage probe and a reference electrode at the location of an anomaly on the surface of the tire. The apparatus and method are configured to determine a precise azimuthal and radial position on the tire of the electrostatic discharge. The conductive spring electrode can have a length sufficient to ensure contact with a given point on the tire surface during a charge cycle for the high voltage probe at increased tire surface speeds.

  • Publication number: 20130099123
    Abstract: A tire surface anomaly detection system and method are disclosed. The system and method are generally based on the principle that a tire surface anomaly will have a different heat transfer rate than that of the uniform mass surrounding the tire surface anomaly. Embodiments of the present disclosure apply thermal energy to the surface of a tire and monitor the infrared energy at the surface of the tire to generate one or more infrared images of the surface of the tire. The infrared images are analyzed by an image processing system to determine and locate thermal gradients on the surface of the tire. The presence of a thermal gradient in the infrared images generally indicates the presence of an anomaly in the surface of the tire. In this manner, the present disclosure provides an objective technique for identifying, locating, and classifying tire surface anomalies.

  • Publication number: 20120305126
    Abstract: Embodiments of the invention include methods and apparatus for adjusting the inflation pressure of a pneumatic tire. Particular methods include the step of arranging a tire in fluid communication with an inflation pressure source on a vehicle. Further steps may include arranging a rotational fluid passage between the tire and a vehicle axle and arranging along the rotational fluid passage an inertia valve that is biased in a closed arrangement while the valve is stationary or rotating below a desired speed about a rotational axis. Such methods may further include the steps of opening the inertia valve when the valve is rotating about the rotational axis at or above the desired speed and adjusting automatically the inflation pressure of the tire through the rotational fluid passage while the valve is open. Other embodiments comprise a system for adjusting the inflation pressure of a pneumatic tire.
