RECOGNIZING TIRE SENSOR LOCATION IN FACTORY MODE FOR TPMS AND SMART ENTRY SYSTEM
First Claim
1. A method for localizing tire sensors on a vehicle, the method comprising:
- 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;
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, recording the identification signals received from the awakened tire sensors and the respective antennas that awoke the respective tire sensors;
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;
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.

Abstract
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.

9. A method for localizing tire sensors on a vehicle, the method comprising:
-
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 to wake up tire sensors mounted within tires on the vehicle, wherein the LF antenna is not located in a wheel well of the vehicle, wherein the LF antenna is closer to a first tire sensor as compared to other tire sensors, and wherein the LF antenna is to configured transmit an LF portable transmission/reception unit wake up field to wake up a portable transmission/reception unit for keyless entry of the vehicle; determining whether a desired number of tire sensors have woken up based on an identification signal being received from a respective awakened tire sensor by a receiver on the vehicle in response to the LF wake up field; localizing the respective awakened tire sensor based on the identification signal received from the respective awakened tire sensor and the respective antenna that awoke the respective awakened tire sensor. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
