A tire inflation viewing device that enables to view the proper operation of the inflation arrangements and that, in turn, enables to determine which of all of the tires is being inflated and has an air leak.

Method and apparatus are disclosed for controlling a TPMS sensor of a vehicle tire. An example vehicle includes a communication module, a tire, and a TPMS sensor corresponding to the tire. The TPMS sensor is configured to receive a target pressure from the communication module, determine a modified target pressure based on vehicle data determined by a vehicle sensor, and, responsive to determining that a measured pressure differs from the modified target pressure by a threshold amount, transmit an alert to the communication module.

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.

In order to intuitively provide optimum tire pressure information corresponding to a weight of a vehicle and state information of a current tire pressure, the vehicle includes: a tire pressure sensor installed on a tire, configured to measure a tire pressure, and to transmit the measured tire pressure as an electrical signal; a storage configured to store optimum tire pressure data corresponding to the weight of the vehicle; a controller configured to calculate the weight of the vehicle, and to compare the measured tire pressure with the optimum tire pressure corresponding to the calculated weight of the vehicle to generate state information of the tire pressure; and a user interface configured to output the state information of the tire pressure.

A method of determining a status of a tyre monitoring device is disclosed. The tyre monitoring device includes a counter initiated on a first use of the tyre monitoring device on a wheel and the method includes: determining a current value of the counter; determining a status of the tyre monitoring device based on the current value of the counter; and providing an indication based on the determined status. In some examples, the status is a remaining service lifetime and the indication may be a replacement notification. A method of cross-checking data between tyre monitoring devices is also disclosed. The method includes receiving data from a plurality of tyre monitoring devices associated with respective tyres of a same vehicle; comparing the received data from different ones of the plurality of tyre monitoring devices; determining inconsistent data associated with at least one of the plurality of tyre monitoring devices based on the comparison; and providing an indication of the inconsistent data.

A visual flow indicator provided on a tire inflation system air hose or rotary union housing.

This disclosure generally pertains to systems and methods related to tire air pressure notifications. An example method that can be executed by a processor in a vehicle can include detecting a tire inflation operation performed upon a wheel of the vehicle and determining that air is escaping out of a tire of the wheel of the vehicle during the tire inflation operation. The processor may then issue an alert based on determining that air is escaping out of the tire. The alert may be provided in various ways such as, for example, via a haptic signal transmitted through a vibration element located in the wheel of the vehicle and/or by waggling the wheel of the vehicle. In an example implementation, waggling the wheel of the vehicle may be carried out by the processor by operating a steering wheel control system of the vehicle.
