本发明涉及车灯，具体地，本发明涉及一种智能车灯模组及其应用方法。更具体地，本发明涉及一种智高分辨率汽车大灯及其高分辨率远光照明控制方法。根据本发明的智高分辨率汽车大灯及其高分辨率远光照明控制方法，可对汽车大灯实施高分辨率远光照明控制，使得所述高分辨率汽车大灯形成的暗区只有对方驾驶员在不同位置时的头部的大小，其他空间依然保持完全没有目标时的高亮度照明，这样不会导致对方驾驶员炫目。The invention relates to a vehicle lamp. In particular, the invention relates to a smart lamp module and an application method thereof. More specifically, the present invention relates to a smart high resolution automotive headlight and a high resolution high beam illumination control method thereof. According to the intelligent high-resolution automobile headlight of the present invention and the high-resolution high-beam illumination control method thereof, high-resolution high-beam illumination control can be implemented on the automobile headlight, so that the dark area formed by the high-resolution automobile headlights is only The size of the head of the opponent's driver in different positions, the other space still maintains high-brightness illumination when there is no target at all, so that the other driver's driver will not be dazzled.
背景技术Background technique
随着车辆夜间行驶安全问题日益突出，越来越多的汽车相关制造商在研发新型智能车灯技术。所谓新型智能车灯技术主要是以实现AFS和ADB功能为目的开发的光型可变车灯。举例来说，具有ADB功能的大灯，配合车辆的探测系统。在侦测发现道路上其他参与者处于大灯照明的某一区间内时，系统可智能的调节该区间的照明亮度甚至直接关闭该区域的照明，形成在整体照明空间内的一个独立的局部暗区，避免对被照明者形成危险的炫目，而没有其他道路参与者的空间继续保持高亮度的照明。在这样的技术支持下，既能保证我方(搭载LED自适应大灯)的前方高质量照明，又不会对道路上其他参与者(比如相向、同向行驶的车辆等)形成危险的炫目，保证了道路上各方的夜间驾驶安全。With the increasing safety of vehicles driving at night, more and more car-related manufacturers are developing new smart car lights technology. The so-called new smart car light technology is mainly a light-type variable headlight developed for the purpose of realizing AFS and ADB functions. For example, a headlight with ADB function, in conjunction with the vehicle's detection system. When it is detected that other participants on the road are in a certain range of headlight illumination, the system can intelligently adjust the illumination brightness of the section or even directly turn off the illumination of the area to form an independent partial darkness in the overall illumination space. The area avoids the dazzling glare of the illuminator, while the space of no other road participants continues to maintain high brightness illumination. With such technical support, we can guarantee the high-quality lighting in front of us (equipped with LED adaptive headlights), and will not pose dangerous glare to other participants on the road (such as facing, co-directional vehicles, etc.). To ensure the safety of night driving on all sides of the road.
现有最好的解决方案之一，是所谓的基于MATRIX技术的矩阵大灯，这种技术方案将整个前照灯的照明空间连续的分割成不同的区块，每个区块由数量不同的LED来负责照明，通过熄灭特定区块的LED，可以提供最小约1°的暗区。One of the best solutions available is the so-called MATRIX-based matrix headlights, which divides the illumination space of the entire headlight into different blocks, each of which is made up of different numbers. The LEDs are responsible for illumination, and by extinguishing the LEDs of a particular block, a dark area of at least about 1° can be provided.
然而，包括上述矩阵大灯技术方案在内，现有实现这种照射范围可调的灯具，都存在一个共同的问题，那就是系统形成暗区的最小角度依然太大。也就是说，形成的暗区虽然可以使得目标车辆的驾驶员不炫目，但是暗区的范围也已经大大超过目标车辆所需的宽度，造成我方需要照明区域的损失。例如前面提到的矩阵大灯，最小可提供0.5-0.1°的暗区。该暗区的实际横向宽度视目标与我方距离而定的，比如在ADB希望发挥作用的400米处，暗区的宽度为(400米*tan 0.5°)3.5米，而实际车宽(以普通乘用车为例) 约1.9米，显然暗区过大了。However, in addition to the above-mentioned matrix headlight technology solution, there is a common problem in the implementation of such a lamp with an adjustable illumination range, that is, the minimum angle at which the system forms a dark region is still too large. That is to say, although the dark area formed can make the driver of the target vehicle not dazzling, the range of the dark area has already greatly exceeded the required width of the target vehicle, causing us to lose the illumination area. For example, the aforementioned matrix headlights provide a minimum of 0.5-0.1° dark areas. The actual lateral width of the dark area depends on the distance between the target and us. For example, at 400 meters where ADB wishes to function, the width of the dark area is (400 m * tan 0.5 °) 3.5 m, and the actual vehicle width (in terms of Ordinary passenger car as an example) About 1.9 meters, obviously the dark area is too big.
所谓ADB功能，最理想的情况是，由智能大灯形成的暗区只有对方驾驶员在不同位置时头部的大小，其他空间依然保持完全没有目标时的高亮度照明，这样对方不会被炫目，我方也可以尽可能的照亮行驶路线上的任何区域。The so-called ADB function, the most ideal situation is that the dark area formed by the smart headlights only has the size of the head when the other driver is in different positions, and the other space still maintains the high-brightness illumination when there is no target at all, so that the other party will not be dazzled. We can also illuminate any area on the route as much as possible.
为此，本领域寻求这样一种智高分辨率汽车大灯及其高分辨率远光照明控制方法，所述大灯及其高分辨率远光照明控制方法可对汽车大灯实施高分辨率远光照明控制，使得所述高分辨率汽车大灯形成的暗区只有对方驾驶员在不同位置时的头部的大小，其他空间依然保持完全没有目标时的高亮度照明，这样不会导致对方驾驶员炫目。To this end, the art seeks such a high-resolution high-speed car headlight and a high-resolution high-beam illumination control method thereof, which can implement high-resolution illumination of automobile headlights The high-beam illumination control makes the dark area formed by the high-resolution car headlights only the size of the head of the opponent driver at different positions, and the other spaces still maintain high-brightness illumination when there is no target at all, so that the other party is not caused The driver is dazzling.

根据本发明，电控偏转反射镜单元由反射镜和电子控制微机械偏转组件构成。电子控制微机械偏转组件可以是静电驱动的，也可以是磁场控制的，目的都在于得到一种受外部电子信号控制实现快速绕轴往复旋转的机械力。而在高速往复旋转过程中，任意特定时刻旋转轴所处相对零位状态的角度可以精确的测得，并时时的向外部电路反馈。反射镜安装于电子控制微机械偏转组件的旋转轴上，反射面的法线与旋转轴垂直。反射镜可在电子控制微机械偏转组件控制下，绕轴旋转，而根据上述电子控制微机械偏转组件的特点，反射面的法线也在高速往复绕轴摆动中，在电子控制微机械偏转组件所规定的旋转角度范围的限制内，形成一条往复扫描的来的线段。如图5，图7至图7-3所示。In accordance with the present invention, an electrically controlled deflection mirror unit is constructed of a mirror and an electronically controlled micromechanical deflection assembly. The electronically controlled micromechanical deflection assembly can be either electrostatically driven or magnetically controlled, with the goal of obtaining a mechanical force that is controlled by external electronic signals to achieve rapid reciprocating rotation about the axis. In the high-speed reciprocating rotation process, the angle of the relative zero state of the rotating shaft at any given moment can be accurately measured and fed back to the external circuit from time to time. The mirror is mounted on a rotating shaft of the electronically controlled micromechanical deflection assembly, the normal of the reflecting surface being perpendicular to the axis of rotation. The mirror is rotatable about the axis under the control of the electronically controlled micromechanical deflection assembly, and according to the characteristics of the electronically controlled micromechanical deflection assembly, the normal of the reflective surface is also in the high speed reciprocating pivoting, in the electronically controlled micromechanical deflection assembly Within the limits of the specified range of rotation angles, a reciprocally scanned line segment is formed. As shown in Figure 5, Figure 7 to Figure 7-3.
将电控偏转反射镜单元的反射镜布置于激光合束单元形成的汇聚光路中，使得汇聚光路经过反射镜产生反射，并被反射至一个新的汇聚点位置。当反射镜在电子控制微机械偏转组件的驱动下高速往复摆动时，汇聚光斑的位置也在不断来回运动或者扫描，轨迹为一条直线(弧线)。如图5，图7至图7-3所示。同时，汇聚光斑在高速往复扫描过程中特定时刻的位置，也可以由当时旋转轴所处特定角度，经电子控制微机械偏转组件及后台控制电路和驱动软件计算得知，并被记录下来。The mirror of the electronically controlled deflection mirror unit is arranged in the converging optical path formed by the laser combining unit such that the converging optical path is reflected by the mirror and reflected to a new convergence point position. When the mirror is oscillated at high speed under the driving of the electronically controlled micro-mechanical deflection assembly, the position of the converging spot is also constantly moving back or forth, and the trajectory is a straight line (arc). As shown in Figure 5, Figure 7 to Figure 7-3. At the same time, the position of the concentrated spot at a specific moment in the high-speed reciprocating scanning process can also be calculated and recorded by the electronically controlled micro-mechanical deflection component, the background control circuit and the driving software at a specific angle at which the rotating shaft is at that time.
在激光汇聚光斑处布置荧光陶瓷。透射型荧光陶瓷的目的在于将照射于其正面的蓝色单波长光线转换为白色复合波长光线在荧光陶瓷的背面输出，并且荧光陶瓷背面的白色光斑的形状与其正面的激光汇聚光斑的形状一一对应。A fluorescent ceramic is disposed at the laser converging spot. The purpose of the transmissive fluorescent ceramic is to convert the blue single-wavelength light irradiated to the front side thereof into a white composite wavelength light to be output on the back surface of the fluorescent ceramic, and the shape of the white spot on the back surface of the fluorescent ceramic and the shape of the laser focusing spot on the front side thereof are one by one. correspond.
激光汇聚光斑经过设计形成一种竖向的细直线型光斑，因此在透射型荧光陶瓷的背面形成也是对应的一条白色竖向细直线型光斑。当反射镜受控高速往复旋转时，激光光斑也在荧光陶瓷上高速往复着沿一条垂直于电子控制微机械偏转组件旋转轴的直线来回位移(扫描)，而荧光陶瓷背面转换而来的白色光斑也在相应的运动。由于视觉暂留特性，当白色的光斑往复位移速度足够快时，人眼所见的就是在荧光陶瓷的背面形成一个白色的矩形光斑。如图8所示。光斑的高度由激光在荧光陶瓷背面形成的竖向细直线型光斑的竖向长度决定，而光斑的宽度由电子控制微机械偏转组件所规定的旋转角度范围决定。The laser converging spot is designed to form a vertical thin linear spot, so that a corresponding white vertical thin linear spot is formed on the back surface of the transmissive fluorescent ceramic. When the mirror is controlled to rotate at high speed, the laser spot is also reciprocated at high speed on the fluorescent ceramic along a line perpendicular to the axis of rotation of the electronically controlled micromechanical deflection assembly (scanning), while the white spot on the back side of the fluorescent ceramic is converted. Also in the corresponding movement. Due to the visual persistence characteristic, when the white spot reciprocating displacement speed is fast enough, what the human eye sees is to form a white rectangular spot on the back surface of the fluorescent ceramic. As shown in Figure 8. The height of the spot is determined by the vertical length of the vertical thin linear spot formed by the laser on the back side of the fluorescent ceramic, and the width of the spot is determined by the range of angles of rotation specified by the electronically controlled micromechanical deflection assembly.
外部电路和软件可以时时得知反射镜在高速往复偏转时，相对于零位状态的角度，特定时刻荧光陶瓷背面的细直线状白色光斑，在如前所述由视觉暂留效应形成的白色大矩形光斑中的具体位置就是可以通过简单计算得到。The external circuit and software can always know the angle of the mirror relative to the zero state when the mirror is deflected at high speed. The thin linear white spot on the back side of the fluorescent ceramic at a specific moment is white which is formed by the visual persistence effect as described above. The specific position in the rectangular spot can be obtained by simple calculation.
投影透镜组放置于荧光陶瓷的背面，其目的在于，将所述荧光陶瓷背面由视觉暂留 效应形成的白色光斑放大投影出去，投影在一定距离的屏幕上时，由于视觉暂留的效果，依然是一个放大的白色矩形光斑，从而形成基础的远光光型，提供基本的汽车远光照明功能。如图8所示。The projection lens group is placed on the back side of the fluorescent ceramic, the purpose of which is to temporarily retain the back surface of the fluorescent ceramic The white spot formed by the effect is enlarged and projected. When projected on a certain distance screen, due to the effect of persistence of vision, it is still an enlarged white rectangular spot, thus forming a basic high beam type, providing basic high beam illumination. Features. As shown in Figure 8.
根据前述推理可得，透过透镜组投射出去的整体远光光斑，是由高速往复线性运动的竖向细直线白色光斑利用人眼视觉暂留效应实现的，那么特定时刻被投影出去放大的白色竖向细直线型光斑相对于整个视觉暂留形成的矩形照明光斑的位置就也是可知的。According to the foregoing reasoning, the overall high beam spot projected through the lens group is realized by the vertical thin white spot of the high-speed reciprocating linear motion using the persistence effect of the human eye, and then the projected white is projected at a specific moment. The position of the vertical thin linear spot relative to the rectangular illumination spot formed by the entire visual persistence is also known.
所述电控偏转反射镜单元的旋转角分辨率最大可达到。例如，最终通过投影透镜组透射出去的光斑最大横向角度是±20°，一维电控偏转反射镜单元可以将这个角度范围划分份，实时感应特定时刻反射镜偏转在那个角度上，即投影后由视觉暂留效果形成的大矩形光斑内，不断横向往复扫描的竖向细直线型光斑在那个角度或者说位置上，其角分辨率达到40°/＝0.001°。在白色竖向细直线型光斑扫描过程中的任意位置上关闭激光器，就可以形成一个特定的暗区。也就是说，理论上本发明所描述的新型智能大灯模组可提供0.001°的暗区，远超现有技术方案。The rotational angular resolution of the electronically controlled deflecting mirror unit is maximized. For example, the maximum lateral angle of the spot transmitted through the projection lens group is ±20°, and the one-dimensional electronically controlled deflecting mirror unit can divide the angular range into parts, and real-time sensing the deflection of the mirror at a certain time, that is, after projection In the large rectangular spot formed by the visual persistence effect, the vertical thin linear spot that continuously scans in the transverse direction has an angular resolution of 40°/=0.001° at that angle or position. By turning off the laser at any position during the white vertical thin line spot scanning process, a specific dark area can be formed. That is to say, in theory, the novel smart headlight module described in the present invention can provide a dark area of 0.001°, far exceeding the prior art solution.
使用摄像头等探测工具，发现道路上的其他参与者，并判定其相对于我方车辆的位置需要对其进行远光光型的遮蔽时，只要当不断往复扫描激光光束，在扫描光斑经过与道路上其他参与者相对应的位置时关闭激光器，即可形成所需的远光光型内、局部的遮蔽光型。如图9所示。Using a probing tool such as a camera to find other participants on the road and determining that their position relative to our vehicle requires a high beam type of shadowing, as long as the laser beam is continuously reciprocated, the scanning spot passes through the road Turning off the laser when the other participants are in the corresponding position can form the desired high-beam type and partial shielding light type. As shown in Figure 9.

The spot, and due to the characteristics known from the real-time deflection angle of the electronically controlled micromechanical deflection assembly, achieves high angular resolution within the broadened spot. After the transmissive fluorescent ceramic is converted into white light and projected by the projection lens group, the above properties are completely preserved.
根据本发明，利用激光汇聚光斑尺寸可以非常小的特性(汇聚在荧光陶瓷上的光斑的横向宽度可轻松实现0.3mm以下)，最终投影出去到前方光斑的横向实际角分辨率可实现0.05°以下。According to the present invention, the spot size of the laser can be very small (the lateral width of the spot concentrated on the fluorescent ceramic can be easily achieved to be 0.3 mm or less), and the lateral actual angular resolution of the projected front spot can be 0.05 or less. .
例如，根据简单的计算可知，在400米的照射距离下，本发明所述系统的最小暗区 为tan0.05°X 400＝0.35米，可以实现只对目标车辆的驾驶舱进行遮蔽，而其他空间依然保持照明的能力，这样目标车辆的驾驶员不会被我方车辆的远光炫目，而目标车辆除去驾驶舱位置外，其他部分依然可被我方远光照亮，保证了我方驾驶员颗第一时间发现目标车辆，相比现有方案大幅度提升了ADB系统的性能。For example, according to a simple calculation, the minimum dark area of the system of the present invention at an illumination distance of 400 meters For tan0.05°X 400=0.35m, it is possible to shield only the cockpit of the target vehicle, while other spaces still maintain the ability to illuminate, so that the driver of the target vehicle will not be dazzled by the high beam of our vehicle. Apart from the cockpit position of the target vehicle, other parts can still be illuminated by our remote light, which ensures that our driver's first time to find the target vehicle, which greatly improves the performance of the ADB system compared to the existing solution.
