Disclosed are a driver′s biosignal detection system and a drowsy driving detection method using ultra-wide band (UWB). The drowsy driving detection system through UWB positioning includes: a generation module for generating a drowsiness detection signal including an impulse radar in a UWB band; an analysis module for transmitting a drowsiness detection signal and detecting a waveform and a phase change of the electromagnetic signal reflected by a driver; a determination module for determining whether the driver is drowsy based on the electromagnetic wave signal analysis result detected by the analysis module and the vehicle control signal; and a drowsy driving notification module that warns of drowsy driving through the driver′s seat vibration and sound notification when it is determined that the driver is drowsy while driving.
UWB 를 이용한 운전자 생체신호 감지 시스템 및 졸음운전 감지 방법을 개시한다. UWB(Ultra-wide band) 측위를 통한 차량 졸음운전 감지 시스템은 UWB 대역의 임펄스레이더를 포함하는 졸음감지신호를 생성하는 생성모듈; 졸음감지신호를 송출하고, 운전자에 의해 반사된 전자파 신호의 파형 및 위상변화를 검출하는 분석모듈; 분석모듈에서 검출된 전자파 신호 분석 결과와 차량제어신호를 통해 운전자의 졸음여부를 판단하는 판단모듈; 및 운전자가 졸음운전 중인 것으로 판단된 경우, 운전석 진동 및 소리 알림을 통해 졸음운전을 경고하는 졸음운전 알림모듈; 을 포함한다.
