Abstract
A tracking approach for mobile devices is performed. Responsive to detecting, using a transceiver of the vehicle, a mobile device reaching a first distance from a vehicle, a designated UWB anchor of a plurality of UWB anchors of the vehicle is activated to perform time-of-flight (TOF) distance measurements between the vehicle and the mobile device. Responsive to the TOF distance measurements between the mobile device and the designated UWB anchor indicating the mobile device has reached a closer, second distance from the vehicle, the plurality of UWB anchors are activated to perform trilateration between the vehicle and the mobile device to identify a position of the mobile device. Based on the position, a subset of the UWB anchors of the vehicle are utilized to continue to perform the trilateration, and a remainder of the UWB anchors other than the subset of the UWB anchors are inhibited to save power.
