智能矩阵大灯系统 

技术特点

我司研发的智能矩阵大灯系统（ADB）由控制器、驱动器、ADB模组、近光模组、信号灯等组成，ADB模组内置12或24颗独立控制的LED光源。通过算法控制模组内不同LED进行亮灭组合,可实现数十个亮度独立控制的远光分区，进而实现远光防眩目，弯道照明，远光增强等功能。软件采用Autosar架构，系统功能安全等级达到ASIL B级。24像素的智能大灯照明系统已经成功量产于Acrfox αT车型。

系统优势：

1.ADB模组光学效率可达到57%，高于市场量产车型所用模组。

2.ADB系统可同时识别多达16个目标。

3.系统不仅可以实现车辆防眩目功能，还可实现基于车灯的弱势交通参与者交互功能。

系统创新点：

1.系统感知层面：传统智能车辆照明系统仅使用前视摄像头，来识别车辆光源信息，基于此来控制每一个LED的亮度，来实现针对车辆的远近光防眩目等功能。本公司开发团队开创性的采用前视摄像头和毫米波雷达信息融合技术，使得摄像头识别到车辆的距离拓展至500米；除此之外，毫米波雷达还可以识别到两轮车，三轮车以及行人（这些目标统称为弱势交通参与者）。

2.功能层面：我司独创性的开发了弱势交通参与者交互功能，当车辆在快速接近弱势交通参与者时，系统可控制目标对应区域的LED以合适的亮度进行一定频率的闪烁，在提醒弱势交通参与者有快速接近的车辆的同时，也提醒驾驶员存在潜在的碰撞风险。这样大大增加了夜间行车的安全性。

3.仿真测试层面：自主开发了光学检测系统，可进行自动化测试，包含11大类900余个场景，极大提高了研发效率。

市场表现 

24 LED像素ADB系统已经量产，搭载至北汽新能源Arcfox αT车型。智能大灯系统会发展成数百颗LED矩阵大灯，基于MEMS技术的百万像素大灯等，市场应用前景广阔。 

Adaptive Driving Beam system contains controller, drviver, ADB module,Low beam module and signal light. The ADB module can hold 12 or 24 LEDs  which can be individually controlled by the controller. We can obtain the individual LED management by software to achieve the ideal LED’s output, making anti-glare function , extra aux light in curve function and light enhancement in highway functionavailable.The software adapts Autosar Classic framework,and function safety level achieves ASIL B. The 24 LED ADB system has been brought into mass production for arcfox αT model。

The advantages:

The optical efficiency can be as high as 57%,which is much higher than the ones in the market.

The ADB system can identify as many as 16 objects(8 objects by camera and the other by radar).

The ADB system not only can output anti-glare

function for the vehicles but also can output interactive functions for the VRU (Vulnerable road user).

Innovation items:

1·For the sensing system, the traditional method employs only camera to identify the light source of the vehicle in the night, and then the controller will order each every LED to preform light distribution to achieve anti-glare function for vehicles. Our method is firstly to employ camera and radar together to fuse the information of the two sensors to make the detection range as far as 500m.What’s more, the radar can offer the object of electric Two-Wheeler and Three-Wheeler and the pedestrian(all the objects can be called VRU as a whole). Based on the fusion results, we developed the interactive function between the vehicle and the VRU on the road. When the vehicle equipped the our ADB system is moving above 30kph,approaching the VRU,the ADB system can identify the angle of the target and enable the specific LEDS to be on and off with some frequency to notify the VRU that there is potential danger coming and at the same time to try to let the driver know that there is VRU nearby. This method can largely enhance the safety for the driver and for the VRU. 

2.Creatively make the method to develop the 11 categories of more than 900 senses during the simulation test on the bench. 

24 LED ADB system has been already mass production for arcfox αT.The ADB system will have more and more LEDs in the near future, and will change into million pixel ADB system based on MEMS technology.
