Design of Intelligent Control System of Automobile Lighting Based on CAN Bus

为解决汽车灯光控制时灯光运行电压与控制预期标准相差较大、影响控制精度的问题,引入CAN总线,开展对汽车灯光智能控制系统的设计研究。通过CAN控制器选型、光照强度检测电路等硬件设计和基于CAN总线的灯光控制指令信号接收与发送、基于光敏检测的会车时灯光智能控制等软件设计,提出一种全新的控制系统。通过对比实验的方式证明,设计的控制系统能够实现对汽车灯光更高精度的调节,可确保汽车灯光的正常使用,满足汽车驾驶人员的使用需求。

In order to solve the problem of the large difference between the operating voltage of the light and the expected control standard during the car light control,which affects the control accuracy,the CAN bus was introduced to carry out the design research on the intelligent control system of the car light.Through hardware design such as CAN controller selection,light intensity detection circuit design,and software design such as CAN bus-based light control command signal reception and transmission,and light-sensitive detection-based intelligent control of lights during meeting,a new control system is proposed.Through comparative experiments,it is proved that the new control system can adjust the car lights with higher precision,ensure the normal use of car lights,and meet the needs of car drivers.
