The invention discloses a passing light illumination control system and method capable of adapting to severe weather, whichrelate to the technical field of automobile intelligent front illumination systems. The method comprises the following steps of 1, judging whether an automobile is in severe weather or not by collecting automobile driving information and road information,2, judging whether other vehicles exist in front of the vehicle or not through the millimeter-wave radar, and determining the specific positions of the vehicles,3, detecting the relative distance L and the relative speed vbetween the front vehicle and the vehiclethrough the millimeter-wave radar, and acquiring the current headlamp deflection angle through a designed headlamp vertical deflection model, and 4, transmitting the headlamp vertical deflection angle signal obtained in the step 3 to a stepping motor control module, and conducting headlamp angle adjustment. The driving safety in cloudy and rainy days can be effectively improved, the glare phenomenon caused to drivers of other vehicles during following and meeting driving is improved, a self-adaptiveillumination system is improved, and the safety of night driving is remarkably improved.

    本发明公开了一种能够适应恶劣天气的近光照明控制系统及方法,涉及汽车智能前照明系统技术领域。包括以下步骤:步骤1:通过采集汽车行驶信息及道路信息,判断是否处于恶劣天气。步骤2:通过毫米波雷达判断车辆前方是否存在其他车辆,并确定其具体位置。步骤3:通过毫米波雷达检测前方车辆与本车的相对距离L和相对速度v,通过设计的前照灯垂直偏转模型获得当前的前照灯偏转角度。步骤4:将步骤3获取的前照灯垂直偏转角度信号输送至步进电机控制模块,进行前照灯角度调节。本发明可有效提高在阴雨天气的行车安全性,改善了在跟车及会车行驶时对其他车辆驾驶员造成的眩光现象,改进了自适应照明系统,显著提高了夜间行车的安全性。
