A driver biometric signal detection system and a drowsy driving detection method using UWB are disclosed. A vehicle drowsy driving detection system through Ultra-wide band (UWB) positioning comprises: a generation module that generates a drowsiness detection signal including an impulse radar in the UWB band; an analysis module that transmits the drowsiness detection signal and detects the waveform and phase change of an electromagnetic wave signal reflected by a driver; a judgment module that determines whether the driver is drowsy through the electromagnetic wave signal analysis results detected in the analysis module and a vehicle control signal; and a drowsy driving notification module that warns of drowsy driving through driver's seat vibration and sound notification when it is determined that the driver is drowsy 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; 졸 음감지신호를 송출하고, 운전자에 의해 반사된 전자파 신호의 파형 및 위상변화를 검출하는 분석모듈; 분석모듈 에서 검출된 전자파 신호 분석 결과와 차량제어신호를 통해 운전자의 졸음여부를 판단하는 판단모듈; 및 운전자 가 졸음운전 중인 것으로 판단된 경우, 운전석 진동 및 소리 알림을 통해 졸음운전을 경고하는 졸음운전 알림모 듈; 을 포함한다.
