Patent ID: 8564428

Claim:
A vehicle system comprising: tire sensors mounted in, on or adjacent respective tires of a vehicle, each tire sensor being configured to transmit an RF signal, which includes an identification signal associated with the respective tire sensor, and to detect an LF field; low frequency (“LF”) antennas mounted on the vehicle, each antenna being configured to transmit an LF field to wake up two tire sensors; an RF receiver mounted on the vehicle configured to receive the RF signals from the tire sensors after the tire sensors have awakened; a memory; and an electronic control unit (“ECU”) in communication with the antennas, the receiver and the memory, wherein the ECU is configured to receive the identification signals from the tire sensors via the receiver, wherein the ECU is further configured to determine locations of the respective tire sensors based on which antenna woke up the tire sensor transmitting the respective identification signal and whether the identification signal matches other received identification signals, wherein the ECU is further configured to store the identification signals in the memory with the identification signals being associated with the respective tire sensors that transmitted the identification signal, wherein the ECU is configured to store the identification signals in the memory in response to an ignition of the vehicle being turned OFF.
