Abstract: PURPOSE: A drowsy driving detector and a method thereof are provided to judge drowsy driving exactly by sensing a pulse signal of a driver. CONSTITUTION: A drowsy driving detector contains: a sensing block(100) installed to a steering device of a vehicle, and radiating an infrared LED with driver's hands, and receiving reflected signals correspondingly to the luminous infrared LED, and then transmitting the value of a light receiving sensor; and a control block(200) receiving the transmitted value of the light receiving sensor and removing noise, and then abstracting a pulse signal, and comparing the value of the abstracted pulse signal with the preset datum value and judging the drowsy driving.

Abstract: 본발명은졸음운전을감지하는기법에관한것으로, 운전자의손 부분에대해적외선 LED를발광하여그 반사신호를수광하고, 그수광센서값에서노이즈를제거하여맥박신호를추출하며, 추출된맥박신호의값을기 설정된기준값과비교하여졸음운전여부를판단함으로써, 운전자손 부분에대한센싱을통해획득된맥박신호를이용하여졸음운전여부를효과적으로판단할수 있다.
