A tire pressure monitoring system includes a tire valve stem mounted tire pressure gauge and an externally powerable remote display unit. The pressure gauge includes a pressure sensor, a wake circuit, a processor, and a first radio frequency (RF) module. The remote display unit includes a second RF module and a display. The wake circuit is adapted to activate the processor periodically at a predetermined interval of time and causes the processor to receive an output signal from the pressure sensor. The output of the pressure sensor is indicative of a tire pressure detected by the pressure sensor. The remote display unit is adapted to display the measured tire pressure value without any user input.

A tire high temperature forecasting system includes at least one tire that supports a vehicle, and at least one sensor mounted on the tire for measuring a temperature of the tire. An electronic memory capacity is in a unit mounted on the tire for storing tire identification information. A processor is in electronic communication with the sensor and the electronic memory capacity, in which the processor receives and correlates the measured temperature, a time of the temperature measurement, and the tire identification information. Transmission means transmit the measured temperature, a time of the temperature measurement, and the tire identification information to a remote processor. The remote processor executes a forecasting model, and the forecasting model generates a forecast estimate. If the forecast estimate includes a predicted high temperature that is greater than a predetermined high temperature threshold for the tire, an alert is generated by the forecasting model.

A tire condition monitoring system includes a plurality of tire condition acquisition devices that are installed on pneumatic tires and acquires quantities of tire conditions, and a monitoring device that receives a radio signal from each of the tire condition acquisition devices and performs a predetermined process. The monitoring device sequentially specifies tire labels of the tire condition acquisition devices and requests input of tire positions of the tire condition acquisition devices. The monitoring device generates registration information in which a sensor ID and a tire position are associated based on the input results of the tire position.

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 and method of controlling pressure of a tire. The method may include executing a low supply pressure operating mode when an available supply pressure of pressurized gas is less than a target tire pressure. The tire may be inflated with pressurized gas provided at the available supply pressure when an estimated tire pressure is not within a threshold amount of the available supply pressure.

A system for monitoring tire pressure of at least one vehicle tire of a utility vehicle includes a pressure sensor for detecting an internal tire pressure of the at least one vehicle tire and an electrically controllable tire inflation system for varying the internal tire pressure. The system also includes a monitoring unit disposed in communication with the pressure sensor and the tire inflation system. The monitoring unit identifies a defect-induced loss of pressure in the at least one vehicle tire based on the detected internal tire pressure, determines a temporal progression of the detected defect-induced loss of pressure, calculates a volume flow necessary for continuous compensation of the pressure loss based on the temporal progression, and controls the volume flow into the at least one vehicle tire via the tire inflation system.

A method of communicating configuration data of a tire pressure monitoring device configured to be affixed to a wheel is disclosed. The method includes, at the tire pressure monitoring device, receiving a request to confirm configuration data, and responsive to receipt of the request to confirm configuration data, transmitting a configuration data signal which encodes the configuration data. The configuration data signal is configured to be received and understood by a human.

An alarm type determining apparatus includes a state detector, an abnormality state determining unit, a traveling state determining unit, an alarm type determining unit, and a notifier. The state detector is configured to detect a state of a tire of a vehicle. The abnormality state determining unit is configured to determine an abnormality state of the tire, on the basis of the state of the tire detected by the state detector. The traveling state determining unit is configured to determine a traveling state of the vehicle. The alarm type determining unit is configured to determine an alarm type, on the basis of the abnormality state of the tire determined by the abnormality state determining unit and the traveling state of the vehicle determined by the traveling state determining unit. The notifier is configured to make a notification based on the alarm type determined by the alarm type determining unit.

A tire pressure monitoring system (30) includes a data acquisition portion (101) that acquires data indicating a tire pressure and a tire temperature of the tire, from a sensor (50FL), a sensor (50FR), a sensor (50RL), and a sensor (50RR) mounted to the tire; a puncture determination portion (103) that determines whether the tire is punctured, based on a puncture determination threshold defined by a relationship between the tire pressure and the tire temperature; and a warning processing portion (105) that generates a warning indicating that the tire is punctured apart from a warning of a drop of the tire pressure when the puncture determination portion (103) determines that the tire is punctured.

The present disclosure may relate to a method capable of monitoring a tire pressure, and may include estimating a tire necessary air pressure based on a location and an external temperature of a vehicle, determining whether a change in a current applied to an in-wheel motor is included in a preset range, when the vehicle is driving at a uniform speed during a preset time, calculating weights according to a plurality of conditions, respectively, and calculating a tire pressure based on the weights.
