Aspects of the present disclosure are generally related to one or more systems, methods, and devices for providing an integrated tire inflation system, mounted on each tire, wheel, rim, axle, or structure of the vehicle, that communicates with a remote device (e.g., communication device located in the cab of the vehicle and/or a remote network entity) and obtains an optimal tire pressure from the network entity that is calculated to maximize fuel economy, tread life, load, or an environmental condition. In some examples, the integrated telematics system may periodically measure and transmit data associated with the tire to the communication device in the cab and/or to a network entity that may calculate the optimal tire pressure for each tire on the vehicle. The integrated telematics system may receive the optimal tire pressure information from the communication device and/or the network entity and automatically adjust the tire pressure accordingly.

A system is disclosed included but not limited to a wheel having a wheel pressure chamber; a tire having a tire pressure chamber, wherein the tire is mounted on the wheel; a tire pressure sensor inside of the tire pressure chamber for measuring a tire air pressure inside of the tire pressure chamber; a wheel outlet valve between the wheel pressure chamber and the tire pressure chamber; a processor that reads a measure of the pressure inside of the tire pressure chamber from the tire pressure sensor and controls the wheel outlet valve to allow gas from the wheel pressure chamber to flow into the tire pressure chamber to increase the pressure in the tire pressure chamber when the tire pressure is less than a reference tire pressure. A method is provided for using the system.

A method for monitoring a tire condition includes the following steps: sense a rotational speed of a tire of a moving vehicle; when the sensed rotational speed reaches a predetermined rotational speed range, obtain a condition of the rotating tire through at least one sensor to generate a piece of first condition data; compare the first condition data with a plurality of pieces of pavement feature data to obtain the corresponding one; process with the obtained piece of pavement feature data and the first condition data to filter a pavement feature out of the first condition data, generating a piece of second condition data; determine whether the condition of the tire is abnormal based on the second condition data; and send out a warning message when the condition of the tire is determined as abnormal Whereby, the road security is improved.

The tire state detecting device includes a calculating unit that calculates an acceleration difference of the gravitational acceleration value acquired at a first acquiring angle and the gravitational acceleration value acquired at a second acquiring angle; a storage unit that stores a correction formula defined in advance based on an angular difference between the adjacent acquiring angles and an angular difference of the first acquiring angle and the second acquiring angle, and corrects the first acquiring angle to an angle determined in advance from the acceleration difference; a transmission unit that transmits a transmission signal including information indicating the angle determined in advance in addition to information indicating the state of the tire; and a control unit that causes the transmission signal to be transmitted to a wheel position specifying device.

A real time tire pressure sensing system includes sensors to collectively generate signals corresponding to a contained tire air temperature, a contained inflation pressure, and an ambient temperature associated with a tire mounted on a vehicle. A processor determines an effective tire inflation pressure based on the generated signals and further at least on a calculated moving average of the ambient temperature (e.g., over a defined time period such as 24 hours) and generates real time notifications associated with the determined effective tire inflation pressure to specified user interfaces. At least one sensor may be an inflation pressure sensor configured to generate event-based signals corresponding to detected changes per unit pressure. The processor may further generate real time feedback control signals to an automatic tire inflation device, based on the determined effective tire inflation pressure, or enable and prompt manual control of the tire inflation device via the user interface.

A system for detecting pressure and wear conditions of tires that includes a module positioned inside each wheel of a vehicle. The module includes sensors, a processor, a transmitter and a power source for powering the module. The output from the sensors in each wheel is fed to the processors of each wheel for data processing and the data is transmitted by the transmitter in each wheel to a receiver and data processor located outside of the wheels. The data processor is designed to analyze the received processed data from the modules, and to provide alerts based on stored information and by comparing the processed data from the first wheel with the processed data from the second wheel.

A wheel hub assembly apparatus comprising a housing configured for operative fitment to a wheel hub assembly. Also included is at least one air pressure sensor having a fluid connection for in situ fitment to tire valve and configured to selectively sense a pressure of a tire mounted on the wheel hub assembly, a temperature detector configured to detect an ambient temperature within the wheel hub assembly, a display configured to provide external display of information, and a controller arranged in signal communication with the pressure sensor, temperature detector and display, the controller configured to receive sensed pressure and/or detected temperature and to display same via the display.

A tire damage detection system for a vehicle includes: a tire; at least one sensor disposed in association with the tire to detect a noise signal when the tire rolls on a road surface to move the vehicle, the noise signal having a plurality of frequency peaks in a frequency spectrum of the noise signal; and a processor to monitor target frequency peaks of the frequency spectrum to detect damage of the tire, and to generate an alert signal in response to the detection of the damage of the tire.

A transmitter is configured to be integrated with a tire valve attached to a wheel. The transmitter includes a data generating unit, a transmitting unit, and a controlling unit. The data generating unit is configured to generate transmission data. The transmitting unit is configured to transmit the transmission data to a receiver that includes a setting unit that sets a threshold related to control of a vehicle in accordance with a type of the wheel. The controlling unit causes the transmitting unit to transmit the transmission data. The transmission data includes wheel identification information. The wheel identification information is required by the setting unit when setting the threshold and allows the setting unit to recognize the type of the wheel to which the tire valve is attached.

A tire for a vehicle includes: a tread extending in a circumferential direction about a rotational axis of the tire; and wear indicators disposed in the tread and spaced apart from each other to be arranged in the circumferential direction. A harmonic noise signal caused by the tire when the tire rolls on a road surface to move the vehicle has neighboring first and second frequency peaks in a frequency spectrum of the harmonic noise signal, and the number of the wear indicators is in a range of 16 to 96 to generate, and when the tire rolls to move the vehicle at a speed in a target range, the wear indicators cause an additional frequency peak positioned between the first and second frequency peaks in the frequency spectrum when the tread is worn to reach a wear threshold.
