An arithmetic model generation system includes a sensor information acquisition unit, a tire force calculator, and an arithmetic model update unit. The sensor information acquisition unit acquires acceleration of a tire. The tire force calculator includes an arithmetic model for calculating tire force F based on the acceleration, and calculates the tire force F by inputting the acceleration acquired by the sensor information acquisition unit.

The present disclosure relates to a process and a system for manufacturing an HSST tyre, as well as the HSST tyre manufactured by the same. The process for manufacturing an HSST tyre includes a cleaning step, a spraying step, and a forced-cooling step. The cleaning step includes an air-drying procedure for evaporating the isopropanol solution on the tyre to be treated with air-drying gases. The forced-cooling step is configured to forcibly cool the tyre to be treated that has been sprayed with the high molecular organic material. By means of accurate design for each step and procedure, the relying on operator's experience is eliminated and thus the performance stability of the HSST tyre is guaranteed. By means of the air-cooling procedure and the forced-cooling step, the time taken to manufacture an HSST tyre is substantially shortened, making it possible to produce the HSST tyre in a large scale.

The aim of the disclosed solution is to present a method of inserting an insert to a tread a tire such that the insert, particularly a fragile insert such as an insert comprising electronic components, may be protected against gripping and impact forces during its insertion. The disclosed solution is premised on an insert being housed, at least partially, in a sleeve upon and during its installation to a tread of a tire. Thus, the sleeve may be employed to provide protection for the insert against gripping and/or impact forces during the insertion of the insert into the tread a tire.

A tire temperature monitoring system, method, and associated devices for installation into a vehicle. The system and method adapted to determine the optimal tire temperature for increased vehicle performance through the collection of tire temperature, various external conditions, historical data, and predictive algorithms to inform a user to the optimal temperature through a visual display.

The method for manufacturing a tire having a sensor container, includes the steps of a) curing a container unit; b) forming a dummy by filling an inside of the cured container unit with a dummy material in which urethane and a curing agent are mixed; c) attaching the container unit including the dummy formed by curing to a tire; d) curing the tire to which the container unit is attached; e) removing the dummy included in the container unit attached to the cured tire; and f) mounting a sensor at a position where the dummy is removed.

Methods of measuring a thickness of a material are disclosed. An oscillating signal at a measurement frequency is applied to a circuit including an inductive component and a capacitive component provided using a pair of capacitive sensor electrodes adjacent the material. The measurement frequency is less than a resonant frequency of the circuit, and the resonant frequency is based on the inductive component and the capacitive component. Information regarding a value of a measured parameter is generated based on applying the oscillating signal at the measurement frequency to the circuit. A value of the measured parameter is related to the thickness of the material.

A method of determining a road surface condition includes: acquiring, when determining a condition of a road surface being in contact with a tire from a time-varying waveform of vibration of the running tire, the time-varying waveform of vibration having been detected by a vibration detecting means, a plurality of intrinsic vibration modes, from data of the time-varying waveform of vibration of the tire, using an algorithm of empirical mode decomposition; selecting an arbitrary intrinsic vibration mode from the plurality of intrinsic vibration modes; calculating a statistic amount from the distribution of feature data calculated by performing Hilbert transform on the selected intrinsic vibration mode to set the statistic amount as a feature amount; and determining the road surface condition from the feature amount and a feature amount obtained in advance for each road surface condition.
