Claim One:
1. A wheel auto-location method, comprising: receiving at a control unit of a vehicle a radio frequency (RF) transmission that indicates a one-measurement point during a rotation of a wheel and tire pressure monitoring (TPM) sensor parameters, wherein the RF transmission is associated with a phase correlation data storage event trigger; storing a current content of a rolling window of antilock brake system (ABS) data indicative of a wheel phase angle in response to the phase correlation data storage event trigger, wherein a time period covered by the rolling window is the same or greater than a time period between the one-measurement point and a receipt point of the RF transmission, and the current content of the rolling window corresponds to the ABS data between the one-measurement point and the receipt point of the RF transmission; calculating the one-measurement point based on the time period between the one-measurement point and the receipt point of the RF transmission; determining relevant ABS data from the current content of the rolling window of the ABS data based on the one-measurement point over time; converting the relevant ABS data in a histogram array; calculating a confidence interval (COIN) width value from the histogram array; and applying an auto-location algorithm to identify a specific location of the wheel based on a lowest COIN width value where the TPM sensor parameters are associated with the specific location of the wheel.
