An intelligent tire pressure monitoring system and method are provided in present disclosure. The system includes a CAN bus module, a diagnosing module, a processor, a 3G module, a GPS module and a server. The CAN bus module and the diagnosing module detect rotational speed of each tire and steering angle of steering wheel, and send a detecting result data the processor. The GPS module obtains position information of the automobile, and sends it to the processor. The processor calculates and processes the detecting result data and the position information of the automobile, and uploads them to the server through the 3G module. The server calculates a pressuring value of each tire according to the detecting result data, the position information of the automobile, weather conditions of continuous several days, and condition of road traveled by the automobile, and do appropriate treatment.

The present disclosure includes a combination sensor and pressure relief valve. The combination sensor and valve may be used with existing aircraft wheel systems. Wheel systems utilizing the combination sensor and valve are also disclosed.

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.

A method includes an initial trailer health assessment and real-time trailer health monitoring. The initial trailer health assessment includes autonomous pre-trip maneuvers of the autonomous vehicle during a first time period, and detecting a pre-trip vehicle health condition. A vehicle health score is calculated based on the pre-trip vehicle health condition. If the vehicle health score is at least a threshold value, real-time trailer health monitoring is performed during a trip of the autonomous vehicle during a second time period, by actively monitoring vehicle dynamics data and/or image data associated with the autonomous vehicle, to determine a fault condition of the autonomous vehicle. If the fault condition meets a first criteria, a control parameter and/or a travel plan of the autonomous vehicle is adjusted. If the fault condition meets a second criteria different from the first criteria, a signal is sent to cause the autonomous vehicle to cease movement.

A tire pressure monitoring unit is for mounting on a vehicle wheel, having a sensor for measuring the tire pressure, a transmitter and a receiver for wireless data transmission, a memory for storing tire data, and a controller connected to the sensor, the transmitter, the receiver and the memory. The controller writes this tire data into the memory on receipt of tire data received via the receiver and assigns a value to a variable, the value marking this tire data as valid. It is provided that a necessary condition for the variable to be assigned a value which marks the tire data as invalid is that the controller detects a pressure increase that exceeds a predetermined threshold value. In addition, a corresponding method for managing tire data in a data memory of a tire pressure monitoring unit is described.

A tire pressure monitoring system includes tire pressure sensors installed within vehicle tires, a receiver, an alerting device, an electronic input/output device and an electronic controller. The receiver receives tire pressure signals from the tire pressure sensors, The electronic input/output device provides manual input of instruction and data. The electronic controller is configured to monitor tire pressure and in response to tire pressure in each of vehicle tires achieving a change from a first preset tire pressure to a second preset tire pressure the alerting device is operated to alert a person changing the tire pressure that the change has been achieved. The first preset tire pressure corresponds to paved road driving conditions and the second preset tire pressure corresponds to off-road driving conditions.

An assistance method for adjusting the pressure of a tire mounted on a wheel of a motor vehicle having an electronic module adapted to transmit, to an on-board central unit in the vehicle, signals including data representing the pressure of the associated tire, this assistance method includes, in the first place, during an action of adjusting the pressure of a tire, determining, after receiving a number n of initial measurement signals, where n2, the gradient or slope Cd of the straight line representing the variation of the measured value Pm(t) of the pressure as a function of time. 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 tire pressure sensor is provided. The tire pressure sensor comprises a sensor housing having a first engagement portion defining an opening. A pressure sensing element is within the sensor housing and is in fluid communication with the opening of the sensor housing. The tire pressure sensor is configured to engage and be in fluid communication with an over-inflation pressure relief valve. The over-inflation relief valve is engagable in a wheel of an aircraft wheel assembly. The tire pressure sensor is also disengageable from the over-inflation pressure relief valve. A tire pressure sensor assembly and an aircraft wheel system are also provided.

An air supply system on a vehicle having a tire. The system includes a compressor having a supply mode for supplying air to a consumer connected to the compressor. The consumer is provided with a reservoir and the compressor switches to an idle mode when the pressure of the reservoir attains a first predetermined reservoir pressure. During a supply period when the consumer is supplied with air from the compressor, the pressure of at least one tire is measured and prior to a subsequent tire pressure measurement, air is discharged from the reservoir so that the compressor remains in the supply mode and the consumer and/or reservoir continues to be supplied with air.
