Abstract: Embodiments relate to tire localization systems and methods for tire pressure monitoring systems (TPMS). In embodiments, a tire pressure management system comprises a wheel speed sensor (WSS), a tire pressure sensor (TPS) that can comprise circuitry and/or sensors configured to measure or record tire pressure data and TPS phase data, and an electronic control unit (ECU) that can comprise circuitry and/or sensors configured to process the speed sensor data and TPS data. TPMS systems and methods utilize a reference position index transmitted by the TPS to determine a constant value pattern of WSS data representative of a specific tire in order to localize the set of tires.

Abstract: A magnetic sensor may include a first sensing element and a second sensing element. The first sensing element may be capable of sensing a first component of a magnetic field that is non-parallel to an axis formed by an intersection of a first plane and a second plane. The first plane may be a plane in which a tooth wheel rotates, and the second plane may include a first surface of the first sensing element and a second surface of the second sensing element. The first component of the magnetic field may be on the second plane. The second sensing element may be capable of sensing a second component of the magnetic field. The second component of the magnetic field may be on the second plane.

Abstract: A sensor module is provided that includes a magnetic sensor and a microcontroller. The magnetic sensor is configured to measure a magnitude of a magnetic field component of an Earth magnetic field projected on a sensing axis of the magnetic sensor and is configured to generate a measurement signal. The magnetic sensor is configured to rotate about an axis through the Earth magnetic field such that the measurement signal oscillates between a first and second extremas as the magnitude of the magnetic field component projected onto the sensing axis changes due to rotation of the magnetic sensor about the axis. The microcontroller is configured to receive the measurement signal, acquire a predetermined number of measurement samples over a sampling period, calculate a variance value of the acquired measurement samples, and determine whether the magnetic sensor is rotating about the axis based on a threshold test of the variance value.

Abstract: Embodiments may provide a system, a wheel localizer, a wheel localization device, or methods for locating a position of at least one wheel out of a plurality of wheels of a vehicle. In one embodiment, a system comprises a detector that obtains information related to a reference magnetic field in which the at least one wheel rotates, an antilock braking system (ABS) unit that obtains information related to angular rotations of the plurality of wheels, and a locator that determines the position of the at least one wheel based, at least in part, on the information related to the reference magnetic field and the information related to the angular rotations of plurality of wheels, where the position comprises a wheel location from among the plurality of wheels. The reference magnetic field may be the earth's magnetic field.
