본 발명은 자동차의 등(LIGHT)에 관한 것으로, 특히, 회전시 차량의 진행방향과 전조등의 조사방향이 불일치하므로 이로인해 발생하는 불빛의 사각지대를 해소하기 위해, 자동차의 선두 좌/우 끝단에 소정의 설치각도를 가지며, 소정의 제어신호에 의해 점등되는 보조등을 설치한 후, 주변의 조도나 자동차의 회전정도 등에 따라 상기 좌/우측의 보조등을 선택적으로 점등시키므로써 차량 회전시 발생하는 전조등의 사각지대를 없앨 수 있는 자동차 전조등의 사각지대 방지 보조등 및 제어방법에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle's LIGHT, and in particular, in order to solve blind spots of lights generated due to a mismatch between the traveling direction of the vehicle and the headlight irradiation direction. After installing an auxiliary lamp having a predetermined installation angle and lighting by a predetermined control signal, the left / right auxiliary lamps are selectively turned on according to the ambient illuminance or the degree of rotation of the vehicle. The present invention relates to a blind spot prevention auxiliary lamp and a control method of a headlamp of an automobile that can eliminate blind spots of a headlamp.
주지하다시피, 자동차 전도등은, 차량의 선두 좌/우측에 위치하여, 야간 운전시나 기타 필요시 라이트 스위치를 조작하여 점/소등시켰다.As is well known, the vehicle conduction lamp is located at the front left / right of the vehicle, and the light switch is turned on / off at night driving or when necessary.
그러나, 상기와 같은 종래의 장치에 있어서는, 전조등이 차량의 일정위치에 고정되어, 차량의 주행방향과 평행하게 불빛을 비추므로 이로인해 회전시 진행하고자 하는 위치를 비출 수 없다는 문제점이 있었다.However, in the conventional apparatus as described above, the headlamp is fixed to a certain position of the vehicle, there is a problem that can not illuminate the position to proceed during rotation because the light shines in parallel with the running direction of the vehicle.

이하, 상기와 같이 구성된 본 발명 자동차 전조등의 사각지대 방지 보조등 및 자동차 전조등의 사각지대 방지 보조등의 제어방법의 작용 및 효과를 상세히 설명하면 다음과 같다.Hereinafter, the operation and effects of the control method of the blind spot prevention assistance lamp of the present invention headlamp and the blind spot prevention aid lamp of the automobile headlamp configured as described above will be described in detail.
차량이 운행 되면, 마이컴(60)은 상기 전조등상태검출부(10)와 회전방향검출부(20)에서 인가되는 신호를 검출하여 전조등의 점등상태와 자동차의 회전상태를 검출하는 차량회전검출단계(100)을 수행하게 된다. 여기서, 전조등의 점등 유/무를 검출하는 이유는, 전조등이 전조된 상태 이후에야 보조등이 필요한 것이기 때문이다. 즉, 전조등은 어두울 경우에야 비로서 상시적으로 켜게 되는 것으로 본 발명의 보조등은 전조등의 부족한 광량을 보충하기 위한 것이기 때문이다.When the vehicle is driven, the microcomputer 60 detects signals applied from the headlight state detecting unit 10 and the rotation direction detecting unit 20 to detect the lighting state of the headlight and the rotation state of the vehicle 100. Will be performed. Here, the reason for detecting whether the headlight is on or off is that the auxiliary light is necessary only after the headlight is rolled. In other words, the headlight is always turned on only when it is dark because the auxiliary lamp of the present invention is to compensate for the insufficient amount of light of the headlight.
한편, 전조등이 점등된 상태에서 차량이 회전하게 되면, 마이컴(60)은, 상기 외부조도검출부(30)에서 인가되는 신호를 검출하여 차량 외부의 조도가 보조등 없이도 운행이 가능한 조도(A)에 비해 큰지 작은지를 판단하는 상기 외부조도검출단계(200)를 수행하게 된다.On the other hand, when the vehicle is rotated while the headlights are turned on, the microcomputer 60 detects a signal applied from the external illuminance detection unit 30 to the illuminance A where the illuminance outside the vehicle can be operated without an auxiliary light. The external illuminance detection step 200 to determine whether the comparison is large or small.
또한, 상기 외부조도검출단계(200)에서 검출된 차량 외부의 조도가 차량이 주행하기에 적합한 조도(A)보다 크지 않을 경우에는, 상기 회전각검출부(40)와 주행상태검출부(50)를 사용하여 바퀴의 회전각이나 주행속도등을 검출하여 조향속도가 회전속도보다 큰것인가를 검출하는 상기 주행상태검출단계(300)를 수행하게 된다.In addition, when the illuminance outside the vehicle detected in the external illuminance detecting step 200 is not greater than the illuminance A suitable for driving the vehicle, the rotation angle detecting unit 40 and the driving state detecting unit 50 are used. The driving state detection step 300 for detecting whether the steering speed is greater than the rotation speed by detecting the rotation angle or the traveling speed of the wheel is performed.
이때, 조향속도가 회전속도보다 클 경우에는 차량의 진행방향과 전조등의 불빛방향이 거의 일치하는 것으로 판단하여 상기 차량회전검출단계(100)로 복귀를 하여 다음의 회전을 기다리고, 그렇지 않을 경우에는 상기 보조등작동단계(400)를 수행하여 차량의 회전방향을 검출하고 이에 따라 상기 왼쪽보조등(82)이나 오른쪽보조등(81)을 점등시켜 주행하는 방향을 비추게 되는 것이다.At this time, when the steering speed is greater than the rotation speed, the driving direction and the headlight direction of the headlight are determined to be substantially the same, and the vehicle rotation detection step 100 is returned to wait for the next rotation. By performing the auxiliary lamp operation step 400 to detect the rotational direction of the vehicle accordingly to illuminate the driving direction by turning on the left side light 82 or the right side light 81.
이상에서 살펴본 바와 같이, 본 발명 자동차 전조등의 사각지대 방지 보조등 및 그 제어방법은 특히, 차량의 진행방향에 대해 소정의 각도를 가지며, 자동차의 선두 좌/우 끝단에 설치되어 도로 주변의 조도나 자동차의 회전정도 등에 따라 상기 좌/우측의 보조등을 선택적으로 점등시키므로써 차량 회전시 발생하는 전조등의 사각지대를 없앨 수 있는 매우 유용한 발명인 것이다.As described above, the blind spot preventing auxiliary light of the headlamp of the present invention and a control method thereof have a predetermined angle with respect to the traveling direction of the vehicle, and are installed at the leading left / right end of the vehicle to provide illumination around the road. By selectively turning on the left / right side auxiliary lights according to the degree of rotation of the vehicle is a very useful invention that can eliminate the blind spot of the headlamp generated when the vehicle rotates.
