A computer-implemented method of aircraft tire maintenance is disclosed including the steps of receiving data of a plurality of pressure and temperature measurements, each of the plurality of pressure and temperature measurements having an associated time stamp; determining stable points in the plurality of pressure and temperature measurements; and using the stable points for determining tire maintenance.

A warning control unit of this tire air pressure monitoring device starts giving a driver a tire air pressure fall warning when a tire air pressure is equal to or lower than a first threshold. The warning control unit stops the warning when the tire air pressure becomes equal to or higher than a second threshold that is set based on a tire temperature in a case where the warning is being given. The warning control unit uses a constant value unrelated to a detected tire temperature as the first threshold, and uses a value obtained by adding a variable value, which is obtained by adding a positive constant value to a value that increases as a temperature difference obtained by subtracting a tire temperature at the time of the issuance of the warning from a current tire temperature increases, to the first threshold, as the second threshold.

A tire condition detecting apparatus includes a condition detecting section, a transmission section, and a transmission-side control section. The transmission section is configured to transmit a signal that contains information related to the condition of the tire to a receiver, which includes a reception-side control section. The reception-side control section identifies the position of the wheel assembly in which the tire condition detecting apparatus is provided based on the received signal strength indication (RSSI) of the signal. The transmission-side control section is configured to cause a position detecting signal and an instruction signal to be transmitted from the transmission section to the receiver. The position detecting signal is configured to cause the reception-side control section to identify the position of the tire condition detecting apparatus. The instruction signal is transmitted before the position detecting signal is transmitted and instructs the reception-side control section to start obtaining the RSSI.

Next, on receiving each subsequent measurement signal, the remaining time required to obtain the setpoint pressure Pc is deduced from the ratio |Pc-Pm(t)|/Cd, and, on the expiry of this remaining time, initiating a procedure for managing the cessation of the pressure adjustment, and signaling the end of the adjustment.

A method for monitoring tire safety is adopted for use on a vehicle equipped with a plurality of tires, a plurality of tire detection units located respectively on each tire to detect the interior conditions thereof, and an electronic device which forms information link with each tire detection unit. The method includes: each tire detection unit measures a corresponding tire measurement parameter; next, the tire measurement parameter is set in a tire status variation calculation formula and a contour variation calculation formula to calculate a plurality of parameters that represent each tire; next, calculate variation amounts of the parameters in an inspection time and convert to a status gradient data; then judge whether the status gradient data are coincided. Redo execution of the previous steps if the judged outcome is positive; otherwise generate an alarm signal about an abnormal condition through an electronic device to alert the vehicle driver.

Cold check gas pressure readings for the landing gear tires of an aircraft are obtained automatically during normal operation of the aircraft. The automated system (S1, e.g.) includes monitoring aircraft data to determine that the aircraft is at rest on the ground (32,345,36), and electronically monitoring the tire pressure (24). When predetermined cold check conditions have been met; the tire pressure values are automatically stored with a timestamp (38) for later access by a user.

A monitoring system, having a processor, provides pressure warnings associated with a tire of an aircraft When the aircraft is stationary, the processor operates in a maintenance mode and receives a first pressure measurement indicating a pressure of the tire; compares the first pressure measurement with a maintenance mode low pressure threshold, and causes the flight deck display to display a low pressure warning associated if the first pressure measurement is below the maintenance mode low pressure threshold. When the aircraft is in motion, the processor operates in a flight mode and receives a second pressure measurement indicating a pressure of the tire, compares the second pressure measurement with an abnormal pressure threshold which is lower than the maintenance mode low pressure threshold, and causes the flight deck display to display an abnormal pressure warning if the second pressure measurement is below the abnormal pressure threshold.
