A method of checking tyre pressures using a control device having a wireless communication interface and at least one tyre monitoring device is disclosed. Each tyre monitoring device is mounted on a respective wheel of a vehicle and comprises a wireless communication interface and a pressure sensor for sensing an inflation pressure of a tyre on the respective wheel. The method includes, at the control device: receiving an input and, responsive to the input: identifying a plurality of tyre monitoring devices within a wireless communication range of the control device, wherein the identifying comprises receiving responses from each tyre monitoring device within the wireless communication range, each response including a vehicle identifier associated with a vehicle upon which the tyre monitoring device is installed.

A preliminary positioning method for a TPMS uses a receiver to receive a tire pressure signal, then obtains the ID code contained in the obtained tire pressure signal, then compares the ID code with the corresponding ID codes stored in the database, and defines the ID code as a known ID code, when the ID code is found to match with one of the corresponding ID codes prestored in the database. Repeating the above steps until the ID codes of all received tire pressure signals all have been compared. If the number of the known ID codes is equal to the number of the sensors, the known ID codes are designated as specific tires according to an indication of the respective tire pressure signals, so that the positioning function can be achieved in a short period of time.

A tire air pressure detection system and a vehicle body side device to detect air pressure of a plurality of tires. The vehicle body side device causes a transmission unit to transmit to all tire side devices, a transmission stop signal instructing transition to a transmission stop state and then the transmission unit transmits a transmission standby signal at a transmission strength that enables the signal to reach the tire side devices; and then the transmission unit transmits to the one of the tire side devices, a transmission request signal requesting a transmission of a signal including a unique identifier stored in that tire side device; and when it is determined that a reception unit has received a response signal in response to the transmission request signal, the transmission unit transmits a transmission standby signal and a transmission request signal to the tire side device corresponding to the next tire.

A system for monitoring parameters of a vehicle wheel assembly includes a wheel speed sensor configured to produce a wheel speed signal, and a wheel assembly monitoring module operatively connected to the wheel speed sensor. The wheel assembly monitoring module determines a dynamic response of the wheel speed signal at one or more wheel speeds. A wheel assembly health module provides one of a visual output, an audible output, and a haptic output indicating that the wheel assembly has exceeded a selected wheel assembly parameter threshold based on the dynamic response of the wheel speed signal.

This disclosure generally pertains to systems and methods that guard against information piracy by selective activation of tire pressure sensor learning operations in a vehicle. An example method can include receiving, by a processor in a vehicle, a sensor signal from a wheel movement sensor provided in a wheel of the vehicle. The processor may evaluate the sensor signal and detect a tire-changing operation. The tire-changing operation may be detected, for example, based on a major surface of the wheel coming in contact with ground or determining that an angular displacement of a major surface of the wheel exceeds a threshold angle. The processor may then enable a learning mode of operation that can include a wireless pairing of a tire pressure sensor in the wheel to a tire pressure monitoring system of the vehicle. The processor disables the learning mode of operation after a period of time.
