1. An ultra-wide band (UWB) ranging control device comprising:
a memory storing a UWB ranging program; and
a processor configured to execute the UWB ranging program,
wherein the processor extracts combinations of UWB anchors installed in a vehicle, the UWB anchors configured to detect a device, the combinations extracted according to correspondence between each of the combinations and each of the operation scenarios,
wherein the processor controls a ranging operation comprising performing primary ranging using UWB anchors assigned first priority among the extracted combinations of UWB anchors, and wherein the UWB ranging program performs time-hopping and frequency-hopping in an alternating pattern, the alternating pattern alternating between time-hopping and frequency-hopping, and
wherein the processor transmits a wake-up signal for the combinations of UWB anchors according to the operation scenarios, the operation scenarios including driver seat passive keyless entry (PKE), passenger seat PKE, passive trunk, and passive start.
