摘　　要：自适应远光(adaptive driving beam,ADB)是一种汽车智能照明技术,它是整车通过传感器捕获前方道路驾驶环境信息(如车辆、行人等)后,由控制决策算法处理产生适合当前驾驶环境的大灯远光光分布,并由前灯ADB照明单元执行,调节或关闭识别目标所对应的分区亮度。其主要特点是在开启远光时避免对其他道路参与者产生眩目,减少夜间交通事故发生,提高夜间行车安全。但ADB照明效果是由多个独立的照明区域叠加组合而成的,其叠加后的照明均匀性对夜间驾驶感知尤为重要。本文针对ADB光型整体均匀性与其中单个照明区域关闭形成的暗区之间存在的矛盾点,提出了一种新的设计思路及评判方法。结果显示,这种解决方案显著提高了ADB照明的均匀性。Adaptive driving beam(ADB)is a modern automobile intelligent lighting technology.After the whole vehicle throught sensors captures the driving environment information(such as vehicles,pedestrians,etc)on the road ahead through sensors,the distribution of headlight high-distance light which is suitable for the current driving environment is generated by the control decision algorithm,and is executed by the ADB lighting unit of the headlight to adjust or close the partition brightness corresponding to the recognition target.Its main feature is to avoid the glare of other road participants when opening the high beam,reduce the occurrence of traffic accidents at night and improve the traffic safety at night.However,the lighting effect of ADB is composed of several independent lighting areas superimposed,and the lighting uniformity after superimposed is especially important for driving perception at night.This paper will propose a new design idea and evaluation method aiming at the contradiction between the overall uniformity of ADB light pattern and the dark area formed by closing of single lighting area.Results show it significantly improve the uniformity of ADB lighting.
