基于微传感器的智能车灯调节系统(AFS)

Adaptive Front-lighting System(AFS) Based on Micro-sensors

针对目前汽车前照大灯机械式的调光系统,AFS(adaptive Front—lighting System)提供了一种基于微米传感器的智能汽车前照灯调节系统,核心器件为多个微米传感器和两组调节步进电机。传感器包括采集光强信息的CMOS光电传感器、采集转弯角度的转弯传感器、测量车辆上下坡角度的微陀螺仪和微速度计。安装在左、右车灯上的调节步进电机可控制大灯在水平和垂直两个方向上的运动。基于此,AFS可根据汽车行车环境及状态的即时调整车灯作用范围和光照强度实现了车灯调节的智能化,大大降低了夜间行车的安全隐患。

Aiming at the former car headlamps mechanical dimming system, AFS (adaptive Front-lighting System) provides a sensor-based smart car headlights micron conditioning system, the core device for multiple micron sensors and two-step adjustment into the motor. Light intensity sensor includes collecting information CMOS optical sensor, turning angle of turn sensor capture, measure the angle of the vehicle downhill micro gyro and micro speedometer. Adjust the stepper motor is mounted on the left and right headlight headlight movement can be controlled in both horizontal and vertical. Based on this, AFS can instantly adjust the light intensity headlights scope and adjust the lights to achieve the intelligent car driving envi-ronment and according to the state, greatly reducing the security risks of driving at night.
