Abstract: A method of communicating with a tire pressure monitoring system (TPMS) sensor module includes transmitting, by the TPMS sensor module, a TPMS signal that includes a sensor identifier of the TPMS sensor module; performing, by an interface device, an angle of arrival measurement on the TPMS signal to whether an angular direction thereof with respect to an antenna array of the interface device is within a predetermined angular window; and determining, by the interface device, whether or not to communicate with the TPMS sensor module including establishing communication with the TPMS sensor module on a condition that the angular direction is within the predetermined angular window and not establishing communication with the TPMS sensor module on a condition that the determined angular direction is not within the predetermined angular window.

Abstract: 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. Localizing the TPMS sensor module includes measuring a phase of the TPMS signal at each of the plurality of reception antennas such that a plurality of phases corresponding to the TPMS signal are determined, and determining a location of the TPMS sensor module based on the plurality of phases.

Abstract: 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.

Abstract: A tire pressure monitoring system (TPMS) includes a communication interface device configured to communicate with a target TPMS sensor module. The communication interface device include a radio frequency (RF) transceiver configured to generate at least one wake-up signal; an antenna array configured to transmit each wake-up signal as a directional RF beam; a processing circuit configured to monitor for a response signal in response to the antenna array transmitting the at least one wake-up signal; and a power amplifier configured to set a power of each wake-up signal according to an adjustable power setting such that the power of each subsequent wake-up signal is increased in discrete steps until the response signal is received by the RF transceiver.
