Abstract

이 발명은 운전자의 무의식적인 졸음 운전을 감지하고, 그 졸음 정도에 따라 운전자의 주위를 환기시켜, 사고로부터 운전자를 보호한다. 또, 동방향으로 주행하는 타 차량의 운전자가 방어 운전을 할 수 있도록 한다. 이를 위하여, 운전자의 뇌파 상태를 측정하는 단계와; 운전자의 뇌파우 설정된 정상, 도우즈 및 슬립 상태의 뇌파를 비교하고, 운전자의 졸음의 정도를 판단하는 단계와; 상기 운전자의 졸음 정도가 도우즈 상태일 경우 경고수단을 작동시키는 단계와; 상기 운전자의 졸음 정도가 슬립 상태일 경우 경고수단과 함께 안전수단을 작동시키는 단계로 이루어짐을 특징으로 한다.
