基于AFS系统的智能随动车灯设计

本系统对随动转向灯进行闭环设计,本系统的控制中心为具有PID控制功能的51单片机,直接对舵机进行控制,使随动灯跟随转动,利用编码器作为反馈元件对方向盘进行速度反馈,在单片机中形成偏差信号,通过调节转动角度使随动灯达到期望位置,从而实现车灯随动的自动化控制。实验结果表明,整个系统功能稳定、随动灵活,运行时可以减小视野盲区,适用于实际。

AFS-based intelligent follow-up lamp design

The system makes a closed-loop design for the follow-up turn signal. The control center of the system is a 51 single-chip microcomputer with PID control function, which directly controls the steering gear, so that the follower lamp follows the rotation, and the encoder is used as a feedback component to perform speed feedback on the steering wheel. The deviation signal is formed in the single- chip microcomputer, and the follow-up lamp is brought to the desired position by adjusting the rotation angle, thereby realizing automatic control of the follow-up of the lamp. The experimental results show that the whole system is stable in function and flexible in operation, and can reduce the blind area of vision during operation, which is suitable for practical use.
