Abstract: Embodiments relate to tire characterization systems and methods for combining direct tire pressure monitoring systems (TPMS) and tire resonance analysis in indirect tire pressure monitoring systems (TPMS) for the extraction of tire characteristics to characterize other tire parameters. In embodiments, iTPMS and methods that utilize anti-lock braking system (ABS) sensed signals coupled to an electronic control unit (ECU) that may comprise circuitry and/or controllers to process the sensed signals using a resonance frequency analysis (RFA) technique can be combined with direct tire pressure sensor measurements from direct TPMS systems. Because direct TPMS systems deliver a precise value of a tire characteristic (for example, tire pressure), one of the unknown parameters that influence the resonance effects can be removed.

Abstract: The present disclosure is directed towards a sensor interface module that delivers a supply voltage to a plurality of sensors, and which exchanges data signals between the plurality of sensors and a control unit (e.g., an ECU). The sensor interface often employs a single-bit comparator (or a coarse analog to digital converter (ADC), e.g., a 2-bit or 3-bit ADC) to track signals to be exchanged between the sensors and controller over the sensor interface. Compared to power hungry ADC with more bits (e.g., 32 bit ADC), the single-bit comparator/coarse ADC limits hardware complexity and power consumption. In addition, in some embodiments the sensor interface module can include an estimator and assist comparators to speed up the tracking ability of the sensor interface module. In this way, techniques provided herein facilitate reliable, low-power communication between a control unit (e.g., an ECU) and its corresponding sensors.

Abstract: A receiver may receive a pulse width encoded signal. The receiver may determine a position of a transition of a pulse of the pulse width encoded signal by oversampling the pulse width encoded signal with respect to a quantization function. The receiver may determine that the position of the transition deviates from an expected position according to the quantization function by more than a predetermined range. The receiver may generate a signal, indicating an unexpected event, based on determining that the position of the transition deviates from the expected position. The receiver may detect an error in a message corresponding to the pulse width encoded signal based on a check value identified from the pulse width encoded signal. The receiver may adjust, based on the signal indicating the unexpected event, a value, corresponding to the position of the transition, to cause the error in the message to be corrected.
