Description
본 발명은 차량의 헤드램프에 관한 것으로서, 보다 상세하게는 차량이 주행하는 도로의 상황에 따라 헤드램프의 조사각도가 변화될 수 있도록 하는 헤드램프 장치에 대한 것이다.The present invention relates to a head lamp of a vehicle, and more particularly, to a head lamp device for changing the irradiation angle of the head lamp according to the situation of the road on which the vehicle travels.
종래에도 헤드램프가 단순하게 고정된 조사각만을 가지지는 않도록 하는 장치가 많이 개발되어 있는 바, 도 1에 도시된 바와 같이 운전자가 손으로 조작하는 수동스위치(100)의 조작에 의해 헤드램프(102)가 조정엘리먼트(104)에 의해 그 조사각을 달리할 수 있도록 되어 있는 장치가 있고, 도 2에 도시된 것처럼 차량의 하중이 전륜과 후륜 중 일측으로 쏠려있는 경우에 이를 레벨센서(106)에 의해 감지하여 컨트롤러(108)가 자동적으로 조정엘리먼트(104)를 조작하여 헤드램프(102)가 적절한 조사각을 가지도록 하는 장치 등이 있다.Conventionally, many devices have been developed such that the headlamp does not simply have a fixed irradiation angle. As shown in FIG. 1, the headlamp 102 is operated by a manual switch 100 operated by a driver by hand. There is a device in which the irradiation angle can be changed by the adjustment element 104, and when the load of the vehicle is directed to one side of the front wheel and the rear wheel as shown in FIG. And the controller 108 automatically manipulates the adjustment element 104 so that the headlamp 102 has an appropriate irradiation angle.
그러나, 이들 장치만으로는 야간의 경사로나 굴곡로에서는 충분한 시야를 확보할 수 없다. 즉, 상기한 바와 같은 장치는 주로 마주 오는 차량의 시야를 확보해 주면서 적절하게 상하방향으로 헤드램프(102)의 조사각도를 조절하는 데에 주안점이 있으므로, 상기한 것처럼 경사로의 주행이나 굴곡로 주행에서는 운전에 필요한 충분한 헤드램프 조사상태를 확보하기 어려운 문제점이 있다.However, these devices alone do not ensure sufficient field of view on night slopes and bends. That is, the above-described apparatus mainly focuses on appropriately adjusting the irradiation angle of the headlamp 102 in the up and down direction while securing the view of the vehicle facing each other. In this case, there is a problem that it is difficult to secure a sufficient headlamp irradiation state required for operation.
물론, 종래에 야간의 굴곡로 주행시에 주행중인 굴곡로에 연동하여 헤드램프의 조사각도가 조절되는 장치가 개발되어 있지만, 이는 도 3에 도시된 바와 같이 양쪽의 헤드램프(102)가 모두 앞으로의 커브에 대비하여 조사각도가 변경됨에 따라서 당장의 전방 시계가 불량해지는 문제점을 안고 있는 것이다.Of course, in the related art, an apparatus for adjusting the irradiation angle of the headlamps has been developed in connection with a bent road running at night, but this is because both headlamps 102 are forwards as shown in FIG. As the irradiation angle is changed in preparation for the curve, the front vision of the current situation is poor.
이에 본 발명은 상기한 바와 같은 문제점을 해결하기 위하여 안출된 것으로서, 야간의 경사로 주행시와 굴곡로 주행시에 운전자에게 차량의 운전에 필요한 충분한 시야의 헤드램프 조사상태를 구현하여 제공할 수 있도록 한 경사로 및 굴곡로 연동 헤드램프 조절장치를 제공함에 그 목적이 있다.Therefore, the present invention has been made to solve the problems as described above, the ramp to enable the driver to implement the state of the headlamp irradiation state of sufficient visibility required for driving the vehicle during the driving of the road and the bend at night and Its purpose is to provide a bend linkage headlamp control device.

상기한 바와 같은 목적을 달성하기 위한 본 발명 경사로 및 굴곡로 연동 헤드램프 조절장치는 운전석쪽의 헤드램프는 일정한 조사각을 가지도록 설치되고, 조수석쪽의 헤드램프에는 그 조사각이 상하좌우로 변화될 수 있도록 상하조절장치 및 좌우조절장치가 구비되며, 상기 상하조절장치 및 좌우조절장치는 조타각센서와 레이더에 의해 정보를 받아 제어신호를 발생시키는 컨트롤러에 의해 제어되도록 구성된 것을 특징으로 한다.In order to achieve the object as described above, the present invention, the ramp and the curved road interlocking headlamp control device is installed so that the headlamp of the driver's seat has a constant irradiation angle, the irradiation angle of the headlamp of the passenger seat is changed up, down, left, and right. Up and down control device and left and right control device is provided so that the up and down control device and the left and right control device is characterized in that it is configured to be controlled by a controller for generating a control signal by receiving information by the steering angle sensor and the radar.
이하, 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.
도 4는 본 발명 경사로 및 굴곡로 연동 헤드램프 조절장치의 실시예를 도시한 것으로서, 조수석쪽의 헤드램프(1R)에는 그 조사각이 상하좌우로 변화될 수 있도록 상하조절장치 및 좌우조절장치가 구비되며, 상기 상하조절장치 및 좌우조절장치는 조타각센서(3)와 레이더(5)에 의해 정보를 받아 제어신호를 발생시키는 컨트롤러(7)에 의해 제어되도록 구성되어 있으며, 운전석쪽의 헤드램프(1L)는 종래의 일반적인 헤드램프의 설치구조와 같이 별도의 조사각 조절장치가 구비되지 않고 차체에 대해 일정한 상태로 고정되어 있다.Figure 4 shows an embodiment of the present invention ramp and bend linkage headlamp control device, the headlamp (1R) of the passenger seat side, the vertical adjustment device and the left and right adjustment device so that the irradiation angle can be changed up, down, left and right Is provided, the up and down adjustment device and the left and right adjustment device is configured to be controlled by the controller (7) for generating a control signal by receiving information by the steering angle sensor (3) and the radar (5), the headlamp of the driver's seat 1L is fixed to a vehicle body in a state in which a separate irradiation angle adjusting device is not provided as in a conventional general head lamp mounting structure.
물론, 상기와 같이 운전석쪽의 헤드램프(1L)는 우리나라의 경우 좌측의 헤드램프가 되며 조수석쪽의 헤드램프(1R)는 우측의 헤드램프를 일컫는 바, 이는 우리나라와 도로의 통행규칙이 반대인 나라의 차량에서는 반대가 될 것인 바, 그 방향의 주된 규칙은 도로의 중앙선쪽의 헤드램프는 일정한 상태로 고정되도록 하고 그 반대인 노변쪽 헤드램프는 그 조사각이 가변될 수 있도록 하는 것으로, 이는 헤드램프 조사각의 변화에 의해 마주 오는 차량의 상대방 운전자의 시야가 방해받는 것을 방지하기 위한 것이다.Of course, as described above, the headlamp 1L of the driver's seat becomes the headlamp on the left side in Korea, and the headlamp 1R of the passenger seat refers to the headlamp on the right side, which means that the traffic rules of Korea and the road are opposite. The opposite is true for vehicles in the country: the main rule in that direction is to keep the headlamps on the centerline of the road fixed and the roadside headlamps on the opposite side to vary the angle of irradiation. This is to prevent the vision of the other driver of the oncoming vehicle from being disturbed by the change of the headlamp irradiation angle.
여기서, 상기 상하조절장치는 상기 헤드램프(1R)의 램프케이스(9)를 힌지축(11)을 회전축으로 상하로 회전시키는 조정엘리먼트(13)로 구성하였고, 상기 좌우조절장치는 상기 조정엘리먼트(13) 및 헤드램프(1R) 일체를 지지하는 회전판(15)과, 상기 회전판(15)을 원하는 각도만큼 회전시킬 수 있도록 회전판(15)에 설치된 기어(17)에 치합된 스텝모터(19)로 구성하였다.Here, the up and down adjustment device is composed of an adjustment element 13 for rotating the lamp case 9 of the headlamp 1R up and down the hinge shaft 11 to the rotation axis, the left and right adjustment device is the adjustment element ( 13) and the rotating plate 15 supporting the head lamp 1R integrally, and the step motor 19 meshed with the gear 17 installed on the rotating plate 15 so as to rotate the rotating plate 15 by a desired angle. Configured.
또한, 상기 레이더(5)는 현재 AICC(Autonomous Intelligent Cruise Control)시스템에서 사용되고 있는 70 GHz 대역의 밀리미터파 레이더로서 선행하는 길의 요철 및 경사 등을 판정할 수 있다.In addition, the radar 5 is a millimeter wave radar in the 70 GHz band currently used in an AICC (Autonomous Intelligent Cruise Control) system, and can determine unevenness and inclination of the preceding road.
상기한 바와 같이 구성된 본 발명의 작용을 설명하면 다음과 같다.Referring to the operation of the present invention configured as described above are as follows.
차량이 보통의 직선 수평도로를 주행중이다가 전방에 경사로가 출현하면, 상기 레이더(5)는 이를 감지하여 상기 컨트롤러(7)에 신호를 보내고, 상기 컨트롤러(7)는 상기 조정엘리먼트(13)를 조절하여 헤드램프(1R)의 상하 조사각도를조절하는데, 그 효과는 도 5에 도시된 바와 같다.When the vehicle is driving on a normal straight horizontal road and a ramp appears in front of the vehicle, the radar 5 detects this and sends a signal to the controller 7, which controls the adjustment element 13. Adjust the upper and lower irradiation angle of the head lamp 1R, the effect is as shown in FIG.
즉, 종래의 일반적인 차량의 경우에는 도 5나 도 6의 상측에 도시된 것처럼 도로의 경사진 부분에 의해 그 조사범위가 매우 좁아져서 운전자는 운전에 필요한 충분한 시계를 확보하기 곤란한 반면, 하측에 도시된 본 발명의 경우에는 운전석측의 헤드램프(1L)는 종래와 같은 각도 범위내의 도로부분을 밝혀주는 한편 조수석쪽의 헤드램프(1R)는 상하로 조사각도를 변경하여 운전석측 헤드램프(1L)가 조사하는 범위를 넘어선 부분을 조사할 수 있도록 하여 운전자의 야간 시계를 충분히 확보할 수 있도록 하는 것이다.That is, in the case of the conventional general vehicle, the irradiation range is very narrowed by the inclined portion of the road, as shown in the upper side of Fig. 5 or 6, so that it is difficult for the driver to secure a sufficient watch for driving, In the case of the present invention, the headlamp 1L on the driver's side illuminates the road portion within the same angular range as in the prior art, while the headlamp 1R on the passenger's side changes the irradiation angle up and down and the driver's side headlamp 1L. It is to ensure that the driver's night vision can be secured by allowing the user to investigate a portion beyond the range to be investigated.
또한, 차량이 굴곡로를 주행하는 경우에는 운전자의 스티어링휠 조타각이 상기 조타각센서(3)에 의해 감지되어 상기 컨트롤러(7)에 입력되는 바, 상기 컨트롤러(7)는 이를 감지하고 그 조타각에 합당한 각도로 상기 스텝모터(19)를 제어하여 상기 조수석측의 헤드램프(1R)를 좌우로 회전시킨다.In addition, when the vehicle travels on a curved road, the steering wheel steering angle of the driver is detected by the steering angle sensor 3 and input to the controller 7, and the controller 7 detects the steering wheel and steers the steering wheel. The step motor 19 is controlled at an angle corresponding to the angle to rotate the headlamp 1R on the passenger seat side left and right.
따라서, 이 같이 조수석측의 헤드램프만(1R)이 앞으로 나타날 전방의 굴곡로를 향하여 빛을 조사하게 되면 도 7에 도시된 것처럼 운전자는 운전석측의 헤드램프(1L)가 비추는 범위로부터 현재의 진행방향에 대한 시계를 확보할 수 있게 됨과 동시에 앞으로 진행할 굴곡진 부분의 도로에 대한 상황을 조수석쪽의 헤드램프(1R)에 의해 미리 파악할 수 있게 되어 안전운전 및 운전 편의성이 한층 제고된다.Thus, when the headlight on the passenger seat side only 1R irradiates light toward the forward curved path to appear in front of the driver, the driver proceeds from the range of the headlamp 1L on the driver's seat as shown in FIG. It is possible to secure a clock for the direction and at the same time to be able to grasp in advance the situation of the road of the bent portion to be carried out by the headlamp 1R on the passenger side, further improving safety driving and driving convenience.
이상 설명한 바와 같이 본 발명에 의하면, 야간의 경사로 주행시와 굴곡로 주행시에 운전자에게 차량의 운전에 필요한 충분한 시야의 헤드램프 조사상태를 구현하여 제공할 수 있어서 안전운전 및 운전편의성을 향상시킨다.As described above, according to the present invention, it is possible to provide a driver with a sufficient visibility of the headlamp irradiation state necessary for driving the vehicle during driving on a slope and at night, to improve driving safety and driving convenience.
