A tire monitoring system includes an information acquisition unit, a temperature determination unit, and an inflation pressure determination unit. The information acquisition unit acquires measurement data by an inflation pressure sensor and a temperature sensor. The temperature determination unit determines whether the measurement data for temperature is higher than a predetermined threshold value based on the measurement data acquired by the information acquisition unit. The inflation pressure determination unit determines, when the temperature determination unit determines that the temperature is higher than the predetermined threshold value, whether a high temperature state in the tire is caused by a factor on a vehicle side or a tire side based on the measurement data for inflation pressure.

An example sensing arrangement for a tire includes: a substrate configured to couple the sensing arrangement to an inner side of the tire; a deformation sensor supported by the substrate and configured to collect deformation data representing deformation at the inner side of the tire; a control module configured to transmit the deformation data collected by the deformation sensor to a recipient device.

Embodiments included herein are directed towards tire pressure monitoring. Embodiments of the present disclosure may include receiving temperature and history over multiple events of an individual tire and determining a first indication by comparing a relative temperature between various tires during an operation to predict a tire blow out scenario in a vehicle. Embodiments may also include determining a second indication by reviewing decrease in pressure of a wheel of the individual tire over time and comparing the decreased pressure of the wheel with other wheels of the various tires on the vehicle using an algorithm on a system level. Embodiments may further include forming predictive analysis based on the first indication and second indication to recommend further manual investigation of a vehicle usability as an aid in preventive maintenance of the vehicle. Embodiments may further include displaying the recommendation for the preventive maintenance of the vehicle to a user.

A tire air pressure management system (100) includes: an acquisition processing portion (61) that acquires an air pressure and an air temperature of a tire (11) attached to a vehicle (1); a correction processing portion (62) that corrects the air pressure that has been acquired by the acquisition processing portion (61) together with the air temperature, based on a difference between the air temperature and a predetermined reference temperature; and a first output processing portion (63) that outputs determination information that is generated based on the air pressure after correction by the correction processing portion (62) and is used to determine whether or not the tire (11) needs air pressure adjustment.

An apparatus includes a device that is configured to determine a condition of a first tire of a vehicle. At a current point in time the device is also configured to determine, on a basis of pressure measured values with respect to a tire pressure of the first tire at the current point in time and at a preceding point in time, a rate of change of the tire pressure of the first tire. At a current point in time the device is also configured to compare the determined rate of change to a reference rate. At a current point in time the device is also configured to determine the condition of the first tire on the basis of the comparison.

A tire internal pressure management device includes a data acquisition unit that acquires internal pressure time series data and temperature time series data of each tire mounted on a mobile body including an aircraft and a vehicle, a representative value calculation unit that calculates a representative value of internal pressure data subjected to temperature correction for each predetermined period, based on the acquired internal pressure time series data and temperature time series data, and an internal pressure filling timing prediction unit that predicts a timing when an internal pressure value falls below a threshold value that is set in advance as an internal pressure filling timing, based on a transition of the calculated representative value of the internal pressure data.

A system for detecting leaks of tires of a vehicle is provided that includes sensors that measure pressure and temperature of the tires. The system has a processor that obtains the data from the sensors and detects a leak of one of the tires by using a natural leak model and/or a damage comparison model. The natural leak model uses temperature measurements of the tires to detect leakage of the tire which can be a slow leak of the tire. The damage comparison model detects leakage of the tire by comparing it to other tires on the vehicle.

A tire state monitoring system comprises an acquisition device and a control device. The acquisition device is configured to repeatedly acquire a pressure and temperature inside a tire. The control device is configured to: calculate, based on ratios between the pressure and temperature acquired in a first period, a representative value of the ratios in the first period; and compare a ratio between the pressure and temperature acquired in a second period after the first period with the representative value, to determine whether the pressure inside the tire has dropped.
