Abstract

본 발명은 자동차의 차선 감지장치에 관한 것으로, 소정 주파수의 펄스 발진부(1)와; 이를 증폭시켜 발광소자(3)를 구동시키는 발광소자 구동부(2)와; 도로(11)에 빛을 발생시켜주는 발광소자(3)와; 도로(11)의 중앙성 및 차선(12)에 의해 반사된 빛을 수광하는 수광소자(4)와; 입사된 빛을 전기신호로 변환하는 광전변환부(5)와; 광전변환부(5)의 출력신호를 증폭시켜 주는 증폭기(6)와; 차선검지 신호만을 검파하는 동기검파부(7)와; 왜곡된 신호를 정형하는 파형정형부(8)와; 차선이탈상태를 시각적으로 표시해 주는 동작표시 램프(13)와; 부져(10)를 차선이탈을 알리는 경보음 발생부(9)로 구성하여주행중인 자동차가 운전자 부주의로 자기 차선을 벗어나 인접된 차선 또는 중앙선을 넘어서면 즉시 경고음등이 발생되도록 하므로써 인접된 차선을 주행하고 있는 자동차들과의 추동 및 충돌사고와 같은 교통안전사고의 발생을 방지할 수 있어 인명 및 재산상의 피해를 미연에 예방할 수 있는 것이다.The present invention relates to a lane detecting apparatus for an automobile, comprising: a pulse oscillation unit (1) of a predetermined frequency; A light emitting device driver 2 for driving the light emitting device 3 by amplifying the light emitting device; A light emitting element 3 for generating light on the road 11; A light receiving element 4 which receives the centrality of the road 11 and the light reflected by the lane 12; A photoelectric conversion unit 5 for converting the incident light into an electrical signal; An amplifier 6 for amplifying the output signal of the photoelectric conversion section 5; A synchronization detector 7 for detecting only a lane detection signal; A waveform shaping section 8 for shaping the distorted signal; An operation indicator lamp 13 for visually displaying a lane departure state; The buzzer 10 is configured as an alarm sound generating unit 9 for notifying a lane departure so that a warning sound is generated immediately when a driving car leaves its own lane inadvertently and crosses an adjacent lane or a center line, thereby driving an adjacent lane. It is possible to prevent the occurrence of traffic safety accidents, such as driving and collision with cars, which can prevent human and property damage.
