A first tire pressure sensor module is configured to provide information related to a pressure of a tire of a vehicle and comprises a pressure sensor configured to determine the information related to the pressure of the tire. The pressure module further includes a controller configured to selectively operate the tire pressure sensor module in an active state and in an inactive state, wherein an energy consumption of the tire pressure sensor module is lower in the inactive state than in the active state. The controller is further configured to control an output of the information related to the pressure of the tire in the active state, and operate the tire pressure sensor module in the inactive state based on determining that information related to a velocity of the tire indicates a velocity above a threshold.

Method and apparatus are disclosed for localizing vehicle TPMS sensors. An example vehicle includes a plurality of TPMS sensors, an antenna, and a processor. The processor is configured for determining signal strength values between each of the plurality of TPMS sensors and the antenna, and based on the signal strength values, determining a location of each of the plurality of TPMS sensors.

A method of localizing a TPMS sensor module includes transmitting, by the TPMS sensor module, a TPMS signal; and localizing, by a localization module, the TPMS sensor module based on receiving the TPMS signal at a phase array antenna including a plurality of reception antennas each configured to receive the TPMS signal at a different phase, where the plurality of reception antennas include a reference reception antenna and at least one additional reception antenna. Localizing the TPMS sensor module includes measuring a reference phase of the TPMS signal received at the reference reception antenna, measuring a respective shifted phase of the TPMS signal received at each of the at least one additional reception antenna, determining a respective phase shift between the reference phase and each respective shifted phase, and determining a location of the TPMS sensor module based on each determined respective phase shift corresponding to the TPMS signal.

The invention relates to a method for managing data relating to an assembly forming a wheel (R) of a vehicle (C), said wheel (R) including a tyre mounted on a rim, said wheel having a measurement module (110), said tyre having an identifier made up of a radio tag (200) such as an RFID marker, said wheel being capable of having different states: mounted in which said tyre is mounted on the rim; and unmounted in which said tyre is not mounted on the rim, in which the measurement module (110) detects a pressure variation inside the tyre, and in which the storage memory of said measurement module (110) is rewritable, characterised in that said method consists of in the event of a pressure variation, replacing the data stored in the measurement module (110) with new data from another tyre. The invention is useful in the management of data relating to tyres and wheels.

A method of building vehicle data in a tire pressure diagnosis tool includes: building owner information in the tire pressure diagnosis tool; entering a vehicle identification number and a tire identification number; and obtaining a tire pressure sensor identification number and a tire environment parameter value, wherein complete linking data pertaining to every owner identity and vehicle status are built in a tire pressure diagnosis tool to not only enable automobile manufacturers and automobile repair shops to effectuate vehicle maintenance and management conveniently, but also provide vehicle identification numbers and tire identification numbers to a competent authority timely and as needed.

A method of dynamically optimizing antenna performance in a wireless sensor network is set forth, comprising scanning multiple frequency bands via successive ones of a plurality of antennae for receiving indications of signal strength at each antenna for each scanned frequency band; and selecting one of said plurality of antennae having highest signal strength over one of said multiple frequency bands for communication over said one of said multiple frequency bands.

An information transmission system for at least one commercial vehicle includes at least one information sending module, at least one repeating module and at least one receiving module. The information sending module is configured and arranged to send signals defining a message to the repeating module. The repeating module is configured and arranged to enhance the signals and forward the signals to the receiving module. A commercial vehicle and a commercial vehicle combination utilize the information transmission system.

Pairing information signals are transmitted for a selected period of time after the transceiver powers up. Generally identical heartbeat signals are transmitted by the transceiver for a longer period of time than the pairing information signals. When the monitor receives the pairing information, it will connect to the transceiver; however, if the monitor does not receive a selected number, e.g. 3, of heartbeat signals, it will disconnect from the transceiver and enter a standby mode, whereupon if the required heartbeats are received, the monitor will connect to the transceiver emitting them. Once connected in this manner, the monitor is able to process the tire sensor data relayed by the transceiver.

A patch is provided for an electronic device of a tire. The patch includes first and second compartments. The first compartment, which does not include an opening, is structured to house therein an electronic identification module. The second compartment, which includes a reclosable opening, is structured to house therein an electronic module having a complementary function to a function of the electronic identification module. The electronic module is adapted to receive identification data from the electronic identification module.
