The present invention provides a system and method for sensing passengers in a vehicle by using ultra-wide band radar. According to the present invention, values collected using ultra-wide band radar are processed in the time domain, and thus passengers in a vehicle can be sensed more rapidly than the time required to process values in the frequency domain which are collected using ultra-wide band radar in the related art. In addition, according to the present invention, large movements, such as movements of hands or feet made by passengers in a vehicle, and small movements, such as the breathing of passengers sitting still, are sensed using separate data processing procedures, thus enabling more rapid and accurate sensing of the passengers.

    La présente invention concerne un système et un procédé de détection de passagers dans un véhicule à l'aide d'un radar à bande ultra-large. Selon la présente invention, des valeurs collectées à l'aide d'un radar à bande ultra-large sont traitées dans le domaine temporel et ainsi les passagers dans un véhicule peuvent être détectés plus rapidement que le temps requis pour traiter des valeurs dans le domaine de fréquence qui sont collectées à l'aide d'un radar à bande ultra-large dans l'état de la technique associé. De plus, selon la présente invention, de grands mouvements, tels que des mouvements de mains ou de pieds faits par des passagers dans un véhicule, ainsi que de petits mouvements, telles que la respiration des passagers assis sans bouger, sont détectés à l'aide de procédures de traitement de données séparées, ce qui permet une détection plus rapide et plus précise des passagers.

    본 발명은 Ultra-Wide Band 레이더를 이용한 차량내 승객 감지 시스템 및 방법을 제공한다. 본 발명은 Ultra-Wide Band 레이더를 이용하여 수집된 값들을 시간 영역에서 처리함으로써, 종래의 Ultra-Wide Band 레이더를 이용하여 수집된 값을 주파수 영역에서 처리하기 위해서 소요되는 시간보다 신속하게 차량내 승객을 감지할 수 있다. 또한, 본 발명은 차량내 승객이 손 또는 발을 움직이는 것과 같은 큰 움직임과, 승객이 가만히 숨을 쉬고 있는 것 같은 작은 움직임을 각각 별도의 데이터 처리 절차를 이용하여 감지함으로써, 보다 신속하면서도 정확한 승객 감지가 가능하다.
