RECOGNIZING TIRE SENSOR LOCATION IN FACTORY MODE FOR TPMS AND SMART ENTRY SYSTEM

摘要

A method for localizing tire sensors includes determining a wake up field power, transmitting an LF wake up field having the wake up field power from an LF antenna on the vehicle, receiving an identification signal from each tire sensor awakened by the transmitted LF wake up field, and determining whether a desired number of tire sensors have woken up in response to the transmitted LF wake up field based on the received identification signals. When the desired number of tire sensors have woken up, the method can further include recording the identification signals received from the awakened tire sensors and the respective antennas that awoke the respective tire sensors. The method further includes determining whether a desired number of antennas have transmitted a respective LF wake up field. When the desired number of antennas have transmitted a respective LF wake up field, the method can further include comparing the received identification signals and determining locations for the tire sensors based on which respective antenna woke up which respective tire sensor and whether the received identification signals match other received identification signals.
