<p>PROBLEM TO BE SOLVED: To provide a method for determining a location of a smart key.SOLUTION: The location of the smart key is determined in a first place by determining a coordinate of a set of candidate apexes of an array of a receiving antenna in a receiver, based on maximum magnetic field pressure in the receiving antenna caused by transmission of a radio signal (RF) by the smart key. A set of candidate locations of a transmitter are determined based on the coordinate of a set of apexes. A set of final candidate locations are determined based on a predetermined threshold value of voltage. Next, the location of the smart key is determined by combining the final candidate location.</p> |
