【摘要】：为了减少汽车转弯自动照明控制系统数据滤波处理中的延时,在滑动中值滤波方法基础上,提出了一种带补偿的限幅滑动中值滤波算法,通过补偿的方式跟随信号的变化趋势。该算法通过2个步骤完成滤波,先对数据进行带补偿方式的限幅处理,再进行滑动中值滤波处理。该算法综合了滑动中值滤波法的实时性以及限幅滤波法对偶然性干扰滤除的有效性,实现更准确的滤波。仿真与实测结果表明,与滑动中值滤波方法相比较,改进后的算法滤波能够实时地滤除数据中的干扰,处理时间可减少62%,滤波效果较好,且速度信号的数据滞后时间较短,实时性较高,满足系统设计要求。
[Abstract]:In order to reduce the delay in the data filtering processing of auto turn lighting control system, a novel method of amplitude limiting sliding median filter with compensation is proposed based on the sliding median filtering method, which follows the changing trend of the signal through the way of compensation. The algorithm uses two steps to complete the filtering. Firstly, the data is limited with compensation, and then the sliding median filter is processed. The algorithm combines the real-time of the sliding median filtering method and the effectiveness of the amplitude limiting filtering method to eliminate the accidental interference, and realizes more accurate filtering. The simulation and experimental results show that compared with the sliding median filtering method, the improved algorithm can filter the interference from the data in real time, reduce the processing time by 622.The filtering effect is better, and the data lag time of the velocity signal is shorter. High real-time, meet the system design requirements.
