Abstract: Systems and methods are disclosed herein for estimating tread depth remaining on a tire mounted on a vehicle. One or more sensors are provided for detecting operational data associated with the vehicle and tire measurements corresponding to ambient temperature and contained air temperature, which may be directly measured or derived from measured tire pressure. A thermal mass of the tire is estimated based on at least the detected operational data and tire conditions, and a current tread depth of the tire is estimated based at least in part on the respective estimated thermal mass. In certain embodiments, the thermal mass estimation may be performed using heat transfer models limited to measurements captured during a cooling down phase of the tire while the vehicle is not moving, thereby simplifying calculation of a corresponding time constant.

Abstract: A tire mold has a cavity with a flexible bladder disposed in a central portion of the cavity. The tire mold further includes a first ring connected to a first end of the flexible bladder, and a second ring connected to a second end of the flexible bladder. At least one of the first and second rings is configured to move between a first position and a second position. The flexible bladder is stretched to a maximum axial length when the first and second rings are in a first position. When the first and second rings are in the first position the sum of the first axial length and second axial length is greater than a space between the first ring and the second ring.

Abstract: Tire sensing systems (126) operable to determine one or more physical characteristics of a tire (156) include millimeter wave transmitting and receiving devices (128T;128R). A processor (218) is communicatively coupled with a memory (220) that includes instructions to transmit and receive a millimeter wave (TXs;TXg,RXs;RXg) toward and from the tire (156). Memory (220) also includes instructions to image first and second radial extents (rs;rg) of the tire (156) based on the received millimeter wave (RXs;RXg) as well as instructions to determine a dimensional difference between the first and second radial extents (rs;rg) of the tire (156). Vehicles (100) including such tire sensing systems (126) as well as non-transitory machine-readable storage mediums (220) and methods (300) are also included.

Abstract: An electronics assembly is provided for use with a tire. The assembly includes a plurality of printed circuit boards, each of which includes an electronic device configured to sense a condition of the tire. Attachment pegs are provided to attach the printed circuit boards together in stacked positions that are spaced apart by the attachment pegs. Each attachment peg has a lower end portion configured to attach to any one of the printed circuit boards. Each attachment peg further has an upper end portion configured to attach to any other one of the printed circuit boards. This enables the printed circuit boards to be attached interchangeably between the stacked positions.

Abstract: A tire electronics assembly includes a base and a plurality of modules. The base is mechanically attached to the tire and includes an electronic device. A plurality of mechanical attachment elements are arranged on the base in a circular array. Each module includes an electronic device and a mechanical attachment element. Each mechanical attachment element on a module is configured to releasably mechanically attach to any one of the mechanical attachment elements on the base. In this configuration, the modules are interchangeably mechanically attachable to the base in the circular array. The base further includes a plurality of electrical terminals arranged in a circular array. Each module has an electrical terminal that is configured to releasably electrically connect with any one of the electrical terminals on the base, whereby the modules are interchangeably electrically connectable with the base in the circular array.

Abstract: An electronics assembly includes a base and a plurality of modules. The base is configured for mechanical attachment to a tire. The base includes an electronic device, and also includes a mechanical attachment element. Each module includes an electronic device, a lower mechanical attachment element, and an upper mechanical attachment element. The lower mechanical attachment element on each one of the modules is configured for attachment to the upper mechanical attachment element on any other one of the modules. In this configuration, the modules are interchangeably mechanically attachable to each other in a stacked arrangement. Each lower mechanical attachment element is also configured for attachment to the mechanical attachment element on the base. The modules are thus mechanically attachable to the base interchangeably with each other, which enables any one of the modules to be installed as the lowermost module in the stacked arrangement.
