A computer-implemented method for vehicle wheel position localization includes accumulating in data storage information regarding temperature characteristics corresponding to each of a respective plurality of wheel positions for each of one or more types of vehicles. The information regarding temperature characteristics may be information regarding temperature rise characteristics associated with a given load. Contained air temperature data is collected from sensors respectively associated with a tire mounted on a vehicle. The sensors may for example be TPMS sensors. A local computing unit or remote server identifies a wheel position associated with the tire, based on a comparison of the collected contained air temperature over a period of time with respect to the stored information regarding temperature characteristics. The wheel position information may be implemented to estimate and/or predict tire wear status for the corresponding tire, and optionally further to predict tire traction status further based on collected vehicle-tire data.

A computer-implemented method enables vehicle tire wear prediction based on minimal input data points. Information is aggregated in a hierarchical data structure regarding historical tread values for multiple tires, and respective values associated with the historical tread values for each of multiple parameters that are hierarchically defined from highest to lowest levels. A current tire tread value is provided from a sensor associated with a first tire, and respective values associated with the current tire tread value are provided for each of the multiple hierarchically defined parameters. The current tire tread value is matched with information from the hierarchical data structure corresponding to matching values for one or more of the hierarchically defined parameters having at least a predetermined threshold number of available tread values, and a tire wear rate is predicted for the first tire based at least in part on the matched information from the hierarchical data structure.

A method for controlling, by a remote monitoring and/or control device, an activation of a command in a wheel unit that has previously stored a group of authorized UHF communication devices and checked whether a device that has sent a response message belongs to the group. If it does, the wheel unit sends a series of command-related signaling messages with each message associated with a single command. When the authorized device receives a message relating to a specific command that the authorized device requests to have activated by the wheel unit, the authorized device sends back to the wheel unit a standard response message interpreted as an activation order for the wheel unit to activate the specific command.

A tire is configured to rotate about an axis of rotation. The tire includes a tread block forming part of a tread of the tire and a circuit having a primary capacitive component. At least a part of the primary capacitive component is arranged a first distance from the tread and inside the tread block and a primary inductive component of which at least a part is arranged a second distance towards the interior of the tire from the tread. The tire includes an interrogator having an electric source, a communication circuit, and a secondary inductive component.

The tire sensing and analysis system may comprise a measurement device and local application software. The measurement device may make contact with a tire of a vehicle such that the measurement device is positioned at a specific distance and orientation relative to the tire. The measurement device may capture multiple images of the tire using an RGB camera and a pair of infrared cameras. The local application software may analyze the images and may construct a 3D mesh describing the 3-dimensional contours of the tread. The local application software may determine a tread depth, tread issues, and tire condition and may display status and warning messages on a display unit that is coupled to the measurement device. The measurements may be communicated to remote application software for additional analysis. As non-limiting examples, the remote application software may detect specific tire wear patterns and may transmit a report to share results of the analysis.
