Research of Vehicle Lamp Control System Based on Acceleration Sensor

针对现有车灯技术中系统构成复杂、生产成本高等问题,提出了一种基于加速度传感器的车灯控制系统及其控制方法,其包括BCM、 G-sensor控制单元、车灯控制单元。该控制系统采用加速度传感器替代传统技术中的前后车身高度传感器,进而实现对车身姿态的实时监测,是对现有车灯AFS功能的一次技术升级,大大降低了线束成本、硬件成本及安装调试等成本。同时,以数字信号替代传统的模拟信号,信号稳定上得到了较大的改善。

Aiming at the problems of complex system structure and high production cost in the existing lamp technology,a lamp control system and its control method were put forward based on acceleration sensor,which included BCM,G-sensor control unit and lamp control unit.In this control method,the acceleration sensor is used to replace the front and rear body height sensors in the traditional technology,so as to realize the real-time monitoring of the body posture.It is a technical upgrade of the existing AFS function of the vehicle lights,which greatly reduces the harness cost,hardware cost,installation and debugging costs.At the same time,the traditional analog signal is replaced by digital signal,which greatly improves the signal stability.
