The invention provides a vehicle and a headlamp adjusting device and method thereof. The headlamp adjusting device comprises a light sensing unit; a dipped headlight control unit; the high beam control unit is connected with the high beam; a suspension height sensing unit; a vehicle-mounted MPC; a speed detection unit for detecting an acceleration of the vehicle; the central control unit is used for acquiring the vehicle body posture change of the vehicle according to the wheel suspension height, the front road condition and the acceleration and controlling the dipped headlight control unit to adjust the height of the dipped headlight according to the vehicle body posture change; the central control unit is further used for controlling the high beam control unit to adjust the irradiation area of the high beam according to the position information of the front vehicle, the distance information of the front vehicle and the intensity of the ambient light. According to the invention, the dynamic adjustment of the high beam irradiation area can be realized, and the dynamic adjustment of the low beam irradiation height can also be realized, so that the irradiation effect can be improved during driving, the occurrence rate of traffic accidents can be effectively reduced, the cost is low, and industrialization is easy.
本发明提供一种车辆及其前照灯调节装置、方法,装置包括:光感单元;近光灯控制单元;远光灯控制单元,远光灯控制单元与远光灯相连;悬架高度感应单元;车载MPC;速度检测单元,用于检测车辆的加速度;中心控制单元,用于根据车轮悬架高度、前方路况、加速度获取车辆的车身姿态变化,根据车身姿态变化控制近光灯控制单元调节近光灯的高度,中心控制单元还用于根据前方车辆的位置信息、前方车辆的距离信息、环境光的强度控制远光灯控制单元调节远光灯的照射区域。本发明既可实现远光照射区域的动态调节,又可实现近光照射高度的动态调节,从而可以在行车时提高照射效果,有效降低交通事故的发生率,且成本低、易于产业化。
