주행상태에 따른 자동차 전조등의 제어장치Control device of headlights according to driving conditions

본 발명은 주행상태에 따른 자동차 전조등의 제어장치에 관한 것으로서, 상세하게는 차량의 좌우회전과 저속 및 고속 등 주행상태에 따라 자동적으로 필요한 조명각도와 조명량으로 전환될 수 있도록 한 주행상태에 따른 자동차 전조등의 제어장치에 관한 것이다.The present invention relates to a control device for a vehicle headlight according to a driving state, and more particularly, according to a driving state so that the vehicle can be automatically switched to the required lighting angle and the amount of light according to driving conditions such as left and right rotation and low speed and high speed of the vehicle. The present invention relates to a control device for an automobile headlight.

일반적으로 차량의 전조등(HL ; Head Light)은 도 1에 도시한 바와 같이 차량의 전단 소정부위에 설치되어 야간주행시 운전자의 스위치 작동에 의해 차량의 주행방향 전방을 조명하도록 하는 것이다.In general, a head light (HL) of the vehicle is installed at a predetermined front end of the vehicle as shown in FIG. 1 to illuminate the driving direction forward of the vehicle by a switch operation of the driver during night driving.

이는 내부에 전원의 접속으로 점등되는 램프가 구비되고, 이러한 램프로부터 발광된 빛을 반사시켜 전면으로 조사하도록 하는 반사경이 구비된 구성으로 되어 있다.It is provided with a lamp which is provided with a lamp which is turned on by the connection of a power source inside, and is provided with a reflector which reflects the light emitted from this lamp and irradiates it to the front surface.

그러나 상기한 일반적인 종래의 전조등은 차체에 고정되어 있어서 차량의 코너링시 운전자가 스티어링휠을 돌려 앞바퀴가 방향 전환된 상태로 되어도 전조등(HL)은 항시 차체의 전방을 조명하도록 되어 있는 것이다.However, the above-described conventional headlights are fixed to the vehicle body so that the headlight HL always illuminates the front of the vehicle body even when the driver turns the steering wheel to turn the steering wheel when cornering the vehicle.

따라서 차량의 좌우회전에 따른 코너링시 진행방향을 조명하는 것이 불가능하고 고속주행시 속도에 따른 전방 시야확보를 위하여 보다 더 전방시계조명이 필요함에도 불구하고 대향 차량의 주행에 지장을 주게 되는 하이빔(High Beam)모드 외에는 별도의 방법이 없어 주행상황에 따른 야간시계확보에 불편하다는 문제점이 있었다.Therefore, it is impossible to illuminate the direction of travel when cornering according to the left and right rotation of the vehicle, and the high beam that hinders the driving of the opposite vehicle despite the need for more forward-looking lights to secure the forward vision according to the speed at high speeds. There is a problem that it is inconvenient to secure the night vision according to the driving situation because there is no separate method except) mode.

따라서 본 발명은 상기한 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은 차량의 코너링시 주행 방향에 따라 자동적으로 전조등 조사를 조절할 수 있도록 하며, 차량의 저속과 고속주행에 따라 상황에 알맞는 시계확보를 이룰 수 있도록 한 주행상태에 따른 자동차 전조등의 제어장치를 제공하는 데 있다.Therefore, the present invention has been made in view of the above problems, the object of the present invention is to adjust the headlight irradiation automatically according to the driving direction when the corner of the vehicle, the clock suitable for the situation according to the low-speed and high-speed driving of the vehicle It is to provide a control device for the vehicle headlights according to the driving conditions to achieve the secured.
