The system can provide the indication to perform the type of maintenance for the tire during the time interval and the at least one tire maintenance category.

A device for detecting an abnormal state of a tire includes a wireless transceiver spaced apart from the tire and coupled to a vehicle, where the wireless transceiver transmits a radio signal to a ground surface and acquires delay information required to receive a reflected wave from the ground surface, and a control module that calculates a reference distance between the wireless transceiver and the ground surface based on the delay information, and detects an abnormal state of the tire, based on a reference distance change.

A tire sensor container system is provided. A tire includes a carcass toroidally extending from a first bead area to a second bead area, and an innerliner formed on an inner surface of the carcass. The tire sensor container system includes a tire pressure monitoring system sensor, which in turn includes a rigid housing that is formed with an oval shape. A flexible container is mounted to the innerliner. The container includes a base and a wall extending radially outwardly from the base, and the wall terminates in a lip. The container wall is formed with an oval shape that cooperates with the shape of the tire pressure monitoring sensor housing. A cavity is defined by the base, the wall, and the lip, and cavity receives and secures the tire pressure monitoring system sensor. The system reduces sensor rotation and maintains consistent sensor orientation to improve sensor functionality and longevity.

A tire position determination system provided in a vehicle including a first tire and a second tire includes an initiator that transmits a command signal, a first detector attached to the first tire, a second detector attached to the second tire, and a monitoring unit. A distance between the first tire and the initiator is equal to or shorter than a distance between the second tire and the initiator. Each of the first detector and the second detector includes an acceleration sensor. A detection signal includes a detection value from the acceleration sensor. The monitoring unit performs determination processing for determining a position of the first tire and a position of the second tire based on positional relation between the detector and the initiator estimated from the detection value from the acceleration sensor.

An apparatus, method and computer program product are provided for predicting road locations that are likely to induce tire pressure changes. In one example, the apparatus receives historical data of an event in which a first vehicle is impacted by a first tire pressure change at a first road segment. The historical data indicates point-of-interest (POI) information associated with the first road segment. The apparatus trains a prediction model using the historical data. The prediction model is configured to determine a likelihood in which a second road segment induces a second tire pressure change for a second vehicle based on POI information associated with the second road segment.

A tyre monitoring device configured to be mounted on a wheel is described. The device includes a pressure sensor for sensing an inflation pressure of a tyre on the wheel; a wireless communication interface configured to receive data indicative of a command to indicate tyre pressure; a storage storing a predetermined pressure value; an indicator configured to provide a first indication and a second indication, wherein the first indication is different from the second indication; and a processing system configured to operate the indicator to provide the first indication or the second indication responsive to receipt of the command to indicate tyre pressure, and based at least in part on the inflation pressure and the predetermined pressure value.

A method for communication of a plurality of wheel units with one another and with a device for remotely monitoring and/or controlling the wheel units, the wheel units measuring a pressure value of a wheel of a motor vehicle as parameter(s). The units are identified beforehand and each wheel unit may identify the other wheel units, the communication taking place in accordance with a communication standard allowing a bidirectional data exchange. A hub wheel unit storing the pressure values measured by each of the wheel units is selected at least temporarily, the other units being peripheral. The hub unit sends a signaling frame in the direction of the peripheral units, received in a peripheral unit through scanning. The pressure values are communicated between the wheel units and a device solely via the hub unit.

A self-monitoring tire includes a tire body and a tire pressure sensor. The tire body includes a tread rubber for contact with ground, a bead for coupling to a rim, and a sidewall structure including two portions disposed at opposite sides of the tread rubber, and extending from opposite sides of the tread rubber to the bead. The tire pressure sensor is disposed between respective outward surfaces of the two portions of the sidewall structure, and secured on or embedded in either one of the two portions of the sidewall structure.
