汽车自适应前照灯系统的研究

Research on auto adaptive front light system for vehicles

针对传统汽车照明系统行驶无法调节照明角度、在弯道内侧易出现盲区等问题,提出了一种前照灯弯道自适应照明系统。以汽车安全刹车距离为有效照明的判断依据,建立前照灯水平方向偏转的数学模型,得到车速、方向盘转角与前照灯水平偏转角度间的关系,并对系统硬件部分进行了选择,给出了汽车AFS系统的控制策略。

In view of the traditional automotive lighting system can not adjust illumination angels, appear the blind section at the inside of the bend, put forward a headlamp adaptive lighting control system at the curve. Basing on the auto safety brake distance, a mathematical model of adaptive lighting control system was established, research the relationship between the auto speed and steering wheel angel with the lights level angel, and design the hardware of the control system, a control strategy is presented.
