상기와 같은 종래의 차량 헤드램프는 차량의 전방을 향하여 차체에 움직이지 않도록 고정되어 있기 때문에, 차량이 직선 도로를 주행하는 경우에는 운전자가 차량 전방의 운전시야를 완전히 확보할 수 있지만 차량이 굽은 도로를 주행하면서 좌회전 혹은 우회전하는 도중에는 운전자가 좌회전 방향 혹은 우회전 방향의 도로 전방의 운전시야를 완전히 확보하지 못하는 문제점이 있다.The conventional vehicle headlamps are fixed to the front of the vehicle so that they do not move on the vehicle body. Therefore, when the vehicle is traveling on a straight road, the driver can completely secure the driving field in front of the vehicle. While driving the vehicle while driving left or right, there is a problem in that the driver cannot fully secure the driving field in front of the road in the left turning direction or the right turning direction.

본 고안은 상술한 종래의 문제점을 해소하기 위한 것으로서, 본 고안의 목적은 운전자가 핸들을 좌회전 혹은 우회전시킴에 따라서 변하는 핸들 각도를 감지한 결과에 따라서 정/역회전 가능한 차량용 스텝 엑추에이터에 연결된 헤드램프를 좌회전 혹은 우회전시켜 운전자가 좌회전 방향 혹은 우회전 방향의 도로 전방의 운전시야를 완전히 확보할 수 있도록 하는 차량의 헤드램프 방향 전환 장치를 제공하는데 있다.The present invention is to solve the above-mentioned conventional problems, an object of the present invention is a headlamp connected to the vehicle step actuator capable of forward / reverse rotation according to the result of the driver senses the steering wheel angle that is changed by turning the steering wheel left or right It is to provide a headlamp direction switching device for a vehicle that allows the driver to fully secure the driving field of the road ahead in the left or right direction by turning left or right.

도 1을 참조하면, 배리스터(10)는 차량의 배터리로부터 공급되는 +12V 구동전원에 혼합되는 과전압 성분을 제거한다.Referring to FIG. 1, the varistor 10 removes an overvoltage component mixed with a + 12V driving power supplied from a vehicle battery.

레귤레이터(11)는 상기 배리스터(10)에 의해 과전압 성분이 제거된 차량 배터리의 +12V 구동전원의 전압을 가변하여 특정한 전압(바람직하게는 +5V)을 나타내는 마이컴 구동전원을 출력한다.The regulator 11 outputs a microcomputer driving power source that exhibits a specific voltage (preferably + 5V) by varying the voltage of the + 12V driving power source of the vehicle battery from which the overvoltage component has been removed by the varistor 10.

핸들 각도 센서(12)는 운전자가 핸들을 좌회전 혹은 우회전할 때마다 변하는 차량의 핸들 각도를 감지하여 핸들 각도 감지신호를 출력한다.The steering wheel angle sensor 12 detects the steering wheel angle of the vehicle that changes each time the driver rotates the steering wheel left or right and outputs a steering wheel angle detection signal.

헤드램프 ECU(13)는 차량의 바디에 장착되어 헤드램프(20)의 온/오프 동작을 제어하고, 상기 핸들 각도 센서(12)의 감지신호를 수신한다.The headlamp ECU 13 is mounted on the body of the vehicle to control the on / off operation of the headlamp 20 and receives a detection signal of the handle angle sensor 12.

마이컴(14)은 상기 레귤레이터(11)로부터 공급되는 전원에 의해 구동하고, 차량용 LIN(Local Interconnect Network) 통신선을 통해 상기 헤드램프 ECU(13)의 핸들 각도 감지신호를 수신하여 해당 감지신호가 나타내는 핸들 각도를 판별한 결과에 따라서 헤드램프 좌회전 혹은 우회전신호를 출력한다.The microcomputer 14 is driven by the power supplied from the regulator 11, receives a handle angle detection signal of the headlamp ECU 13 through a vehicle local interconnect network (LIN) communication line, and handles indicated by the corresponding detection signal. According to the result of the angle determination, the headlamp left turn or right turn signal is output.

드라이브 IC(15)는 상기 마이컴(14)의 회전신호를 수신하고, 수신된 회전신호가 좌회전신호인지 우회전신호인지를 판별하여 헤드램프(20)를 좌회전 혹은 우회전시키기 위한 구동신호를 출력한다.The drive IC 15 receives the rotation signal of the microcomputer 14, determines whether the received rotation signal is a left turn signal or a right turn signal, and outputs a drive signal for turning the head lamp 20 to the left or right.

스텝 엑추에이터(16)는 상기 드라이브 IC(15)의 구동신호에 따라서 정/역회전하여 헤드램프(20)를 좌회전시키거나 우회전시킨다.The step actuator 16 rotates the headlamp 20 to the left or right by forward / reverse rotation according to the drive signal of the drive IC 15.

상기와 같이 구성되는 본 고안에 따른 차량의 헤드램프 방향 전환 장치는 다음과 같이 작동한다.The headlamp direction switching device of the vehicle according to the present invention configured as described above operates as follows.

굽은 도로를 주행하는 차량의 운전자가 핸들을 좌회전 혹은 우회전시키는 경우, 상기 핸들 각도 센서(12)는 이때마다 변하는 차량의 핸들 각도를 감지하여 특정한 각도를 나타내는 핸들 각도 감지신호를 출력하여 상기 헤드램프 ECU(13)로 전달한다.When a driver of a vehicle driving on a curved road rotates the steering wheel to the left or the right, the steering wheel angle sensor 12 detects the steering wheel angle of the vehicle that changes at this time and outputs a steering wheel angle detection signal indicating a specific angle to the headlamp ECU. Deliver to (13).

상기 핸들 각도 센서(12)의 감지신호가 상기 헤드램프 ECU(13)로 입력되면 상기 헤드램프 ECU(13)는 차량용 LIN(Local Interconnect Network) 통신선을 통해 상기 핸들 각도 감지신호를 상기 마이컴(14)으로 전송한다.When the detection signal of the steering wheel angle sensor 12 is input to the headlamp ECU 13, the headlamp ECU 13 transmits the steering wheel angle detection signal to the microcomputer 14 through a vehicle local interconnect network (LIN) communication line. To send.

이에 따라서, 상기 마이컴(14)은 입력된 핸들 각도 감지신호가 나타내는 각도를 분석하여 현재 차량의 핸들이 특정한 각도만큼 좌회전 혹은 우회전되었는가를 판별하고, 그 판별 결과에 따라서 상기 헤드램프(20)를 감지된 각도만큼 좌회전 혹은 우회전시키기 위한 회전신호를 출력하여 상기 드라이브 IC(15)로 전달한다.Accordingly, the microcomputer 14 analyzes the angle indicated by the input steering wheel angle detection signal to determine whether the steering wheel of the current vehicle is turned left or right by a specific angle and detects the headlamp 20 according to the determination result. A rotation signal for turning left or right by a predetermined angle is output and transmitted to the drive IC 15.

상기와 같이 마이컴(14)의 회전신호가 드라이브 IC(15)로 입력되면, 상기 드라이브 IC(15)는 수신된 마이컴(14)의 회전신호가 좌회전신호인지 혹은 우회전신호인지를 판별하고, 그 판별 결과에 따라서 상기 헤드램프(20)를 좌회전 혹은 우회전시키기 위한 구동신호를 출력하여 상기 스텝 엑추에이터(16)로 전달한다.When the rotation signal of the microcomputer 14 is input to the drive IC 15 as described above, the drive IC 15 determines whether the received rotation signal of the microcomputer 14 is a left turn signal or a right turn signal, and determines that. According to the result, a driving signal for rotating the head lamp 20 left or right is outputted and transmitted to the step actuator 16.

이에 따라서, 상기 스텝 엑추에이터(16)는 정회전 혹은 역회전하여 상기 헤드램프(20)를 운전자가 핸들을 특정 각도로 회전시킨 것만큼 좌회전시키거나 우회전시키면 굽은 도로를 주행하는 차량의 운전자는 주행 중에 좌회전 혹은 우회전하면서도 좌회전 방향 혹은 우회전 방향의 도로 전방의 운전시야를 완전히 확보할 수 있다.Accordingly, the step actuator 16 is rotated forward or reverse to rotate the headlamp 20 to the left or right as much as the driver rotates the steering wheel at a specific angle. While turning left or right, the driving field in front of the road in the left or right direction can be completely secured.

상술한 바와 같이 본 고안에 따른 차량의 헤드램프 방향 전환 장치는 운전자가 핸들을 좌회전 혹은 우회전시킴에 따라서 변하는 핸들 각도를 감지한 결과에 따라서 정/역회전 가능한 차량용 스텝 엑추에이터에 연결된 헤드램프를 좌회전 혹은 우회전시키도록 되어 있으므로, 차량이 굽은 도로를 주행하면서 좌회전 혹은 우회전하는 도중에도 운전자가 좌회전 방향 혹은 우회전 방향의 도로 전방의 운전시야를 완전히 확보할 수 있는 장점이 있다.As described above, the headlamp direction switching device of the vehicle according to the present invention rotates the headlamp connected to the vehicle step actuator capable of forward / reverse rotation according to a result of detecting the steering wheel angle which is changed by the driver turning the handle left or right. Since the vehicle is turned to the right, the driver may secure the driving field in front of the road in the left turn direction or the right turn direction even while the vehicle is turning left or right while driving the curved road.

이상에서 설명한 것은 본 고안에 따른 차량의 헤드램프 방향 전환 장치를 실시하기 위한 하나의 실시예에 불과한 것으로서, 본 고안은 상기한 실시예에 한정되지 않고, 이하의 실용신안등록청구범위에서 청구하는 본 고안의 요지를 벗어남이 없이 본 고안이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변경 실시가 가능한 범위까지 본 고안의 기술적 정신이 있다고 할 것이다.What has been described above is just one embodiment for implementing the headlamp direction switching device of the vehicle according to the present invention, the present invention is not limited to the above embodiment, this invention claimed in the following utility model registration claims Without departing from the gist of the invention, anyone with ordinary knowledge in the field to which the present invention belongs will have a technical spirit of the present invention to the extent that various modifications can be made.
