The invention relates to an intelligent vehicle lamp control method for dynamically changing a matrix vehicle lamp irradiation area, and the method comprises the steps: obtaining the position information of a front vehicle through a Fast R-CNN, and obtaining the distance and azimuth angle information of the front vehicle through a millimeter wave radar; and predicting the extinguished lamp bead area of the fixed LED matrix module and the rotation direction and angle of the movable LED matrix module by using the RBF neural network model. The central control unit ECU changes high and low levels output by the PWM controller, pulses output by the PLC respectively adjust the brightness of a lamp bead area in the fixed LED matrix module and the rotating direction and angle of the movable LED matrix module, light compensation is carried out on the lamp bead area extinguished by the fixed LED matrix module, and a larger illumination area is achieved. The problem that a traditional matrix type LED car lamp generates a light ray blind area during car meeting is solved; the requirement of a driver for the safe view during night driving is met, and the night driving safety is improved.
本发明涉及一种动态改变矩阵车灯照射区域的智能车灯控制方法,通过Fast R‑CNN卷积神经网络获取前方车辆位置信息,毫米波雷达获取前方车辆距离、方位角信息;利用RBF神经网络模型预测固定式LED矩阵模组所熄灭灯珠区域、可动式LED矩阵模组所转动方向及角度。中央控制器ECU改变PWM控制器输出的高低电平、PLC控制器输出的脉冲分别调节固定式LED矩阵模组中灯珠区域亮度,可动式LED矩阵模组转动方向及角度,对固定式LED矩阵模组所熄灭的灯珠区域进行灯光补偿,实现更大的光照区域。本发明解决了传统的矩阵式LED车灯在会车时所产生的光线盲区问题;满足驾驶员在夜间行驶对安全视野需求,提升夜间驾驶安全性。
