A tire pressure monitoring system includes a first tire mounted on a first end of an axle and a second tire mounted on a second end of the axle. A first sensor is mounted on the first tire for measuring a pressure, and a second sensor is mounted on the second tire for measuring a pressure. The system includes means for transmitting measured pressure data from the first sensor and the second sensor to a processor. A tire pressure model is executed on the processor, and includes an aggregator that accumulates the measured pressure data from the first sensor and the second sensor. A noise filter filters sensor noise and generates filtered pressure data from the measured tire pressure data. A detection module receives the filtered pressure data and determines when a leak occurs in one of the tires. A leak notification is generated when the leak occurs.

The present disclosure relates to a computer-readable storage medium, and a fault detection method and apparatus. The method includes: obtaining first data of tire pressure sensors of a vehicle in a stopping state and a running state; and performing fault detection according to the first data of the tire pressure sensors in the stopping state and/or the running state, and outputting a fault detection result. According to the solutions provided in the present disclosure, a fault type and a fault source can be quickly and accurately positioned, so that maintenance personnel perform fault maintenance quickly and safely, thereby reducing the costs of maintenance and detection, and effectively improving the efficiency and accuracy of fault detection.

A pneumatic tire (1) having: a toroidal carcass (2), which is comprised of a body ply (3) partially collapsed onto itself and therefore having two lateral flaps; two annular beads (4), each of which is surrounded by the body ply (3) and has a bead core (5) and a bead filler (6); an annular tread (7); a pair of sidewalls (11) arranged externally to the body ply (3) between the tread (7) and the beads (4); a pair of abrasion gum strips (12) arranged externally to the body ply (3) under the sidewalls (13) and at the beads (4); and a transponder (13) which is arranged in contact with the body ply (3) at a flap of the body ply (3) and is located below an edge (19) of the body ply (3) between the edge (19) of the body ply (3) and the bead (4).

An auto-location system for auto-locating a wheel in a vehicle comprises: a sensor module which comprises a sensor adapted for sensing a physical property of the tire when mounted in a tire or on an inner surface of the tire of the wheel, an acquisition system adapted for determining when the part of the tire where the sensor is mounted hits the ground, and forms a contact patch with the ground, by analyzing data from the sensor, and a communication system adapted for transmitting a wireless message, in which a unique identifier is embedded, a transmit delay after the part of the tire where the sensor is mounted hits the ground.

A method of determining the health of a tire on a vehicle includes determining a total number of tire inflation events that have occurred due to a loss of tire pressure. A rate in which the tire inflation events have occurred is determined based on the total number of tire inflation events over a predetermined period of time. The health of a tire is determined by comparing the rate in which tire inflation events have occurred to a threshold rate.

A tire pressure detection system with single antenna includes a detection end 10 and a receiving end. The detection end includes tire pressure detectors to detect the tire to obtain the tire status. The tire pressure detectors outputs the tire status, and the information of the tire status is output in the form of radio frequency signal and Bluetooth signal to the tire-pressure receiving device, the audio-video device and the mobile device so that the users are acknowledged about the information of the tire including tire pressure and tire temperature.

A load-based tire inflation system for a heavy-duty vehicle comprises at least one source of fluid pressure, suspension structure of the heavy-duty vehicle, a tire and wheel assembly and a system to control fluid pressure in the tire and wheel assembly. The suspension structure is located between a frame member and an axle and has a condition indicative of a weight of the heavy-duty vehicle. The tire and wheel assembly is operatively mounted to the axle and is in fluid communication with the source of fluid pressure. The control system controls fluid pressure in the tire and wheel assembly in response to the condition of the suspension structure.

A pressure measuring device for a bicycle has a housing that includes a pressure chamber. The pressure chamber has a valve disposed in a first opening and a second opening into or out of a tire assembly volume of a tire assembly. A sense element is in pressure communication with the pressure chamber along a flow path between the first and second openings.
