Abstract

Disclosed are an ultra wide band ranging control apparatus and an ultra wide band ranging method, and more particularly, a UWB system capable of optimizing a UWB operation of a vehicle by jumping. A UWB system includes a memory in which a UWB communication program is embedded and a processor that executes the program. The processor performs UWB time hopping and frequency hopping to establish a communication channel.

Description

[0001] Cross-references to related applications [0002] This application claims priority and benefit to Korean Patent Application No. 10-2020-0126293, filed September 28, 2020, and Korean Patent Application No. 10-2020-0160544, filed November 25, 2020, the disclosures of which are incorporated by reference Incorporated into this article as a whole. technical field [0003] The present disclosure relates to an ultra-wideband (UWB) ranging control device and a UWB ranging method using the same. Background technique [0004] Ultra-wideband (UWB) is a technology that uses time-of-flight (ToF) technology to calculate the distance between communication objects by multiplying the time required for a signal to reach the communication object by the speed of light. [0005] In the prior art, in order to measure the position of the digital key, seven UWB modules are installed in the vehicle (in the case of a Sports Utility Vehicle (SUV), that is, four UWB modules are installed on the...
