An automatic steering system of a steering headlamp comprises a speed sensor, a six-axis gyroscope, a control module and the steering headlamp. The speed sensor detects vehicle driving real-time speeddata and communicates with the six-axis gyroscope through a serial peripheral interface (SPI), the six-axis gyroscope obtains accelerations and angular speeds of an X axis, an Y axis and a Z axis, and then a quaternion fusion algorithm is used for processing the data to obtain inclination angle data. The inclination angle data is processed by a Kalman filter and then transmitted to the control module, and after the control module outputs a control quantity through a fuzzy control algorithm, the output control quantity is judged to obtain a steering signal and output the steering signal to thesteering headlamp. The whole process needs to depend on an angle sensor, and automatic control of the steering headlamp is completed only by depending on vehicle motion information input by the speedsensor and the gyroscope.

    一种转向大灯自动转向系统,包括速度传感器、六轴陀螺仪、控制模块、转向大灯;所述速度传感器检测车辆行驶实时速度数据,并使用串行外设接口SPI与六轴陀螺仪通信,六轴陀螺仪获取的X轴、Y轴、Z轴的加速度以及角速度,然后使用四元数融合算法对数据进行处理得出倾角数据,倾角数据经卡尔曼滤波器处理后传输至控制模块,控制模块通过模糊控制算法输出控制量之后,对输出的控制量进行判断,得出转向信号,并输出至转向大灯。整个过程,需要依赖角度传感器,仅依靠速度传感器以及陀螺仪输入的车辆运动信息,完成转向大灯的自动控制。
