Abstract
Embodiments relate to indirect tire pressure monitoring systems (TPMSs) and methods that utilize anti-lock braking system (ABS) signals. In embodiments, information from the ABS Hall signal is obtained in analog form, before pulse forming. The information can be analyzed for a resonance frequency within the ABS sensor. In some embodiments, the digitized information can be modulated onto the conventional ABS wheel speed clock signal for transmission to and analysis by the indirect TPMS electronic control unit (ECU). According to embodiments, additional information about higher-order harmonics of the wheel rotation can be provided to the TPMS ECU, which can then calculate a more accurate estimation of tire pressure while reducing warning latency.
