Claim 10:
11. A method comprising:
establishing, with a communication gateway in a vehicle, a Bluetooth low energy (BLE) communication connection with a portable device;
receiving, with a plurality of sensors in communication with the communication gateway, connection information about the BLE communication connection from the communication gateway;
eavesdropping, with the plurality of sensors, on the BLE communication connection based on the connection information;
measuring, with the plurality of sensors, signal information about at least one communication signal sent from the portable device to the communication gateway;
receiving, with a localization module, the signal information from each of the plurality of sensors;
determining, with the localization module, a location of the portable device based on the signal information from the plurality of sensors;
receiving, with a passive entry/passive start (PEPS) system, the location of the portable device from the localization module; and
performing, with the PEPS system, a vehicle function including at least one of unlocking a door of the vehicle, unlocking a trunk of the vehicle, and allowing the vehicle to be started based on the location of the portable device;
wherein the signal information includes a phase angle of the at least one communication signal sent from the portable device to the communication gateway.
