The invention discloses a windscreen wiper control method based on a rainfall change rate. The method comprises the steps that: rainfall values output by a rainfall sensor are collected with delta T as the time interval in a rainfall collection period T, and the rainfall change rate of each collection point is calculated; and the number of the data of the rainfall change rate falling in the rain-free threshold interval, the light rain threshold interval, the medium rain threshold interval and the heavy rain threshold interval in the acquisition period T are put into statistics, the current rainfall state is determined according to the maximum value of the number of the data falling in the four intervals, and the motion state of a windscreen wiper is controlled according to the rainfall state. According to the method of the invention, the rainfall state and the jump of the rainfall state can be accurately judged according to the rainfall change rate, so that the windscreen wiper is controlled to move at a speed suitable for different rainfall states.

    本发明公开一种基于雨量变化率的雨刮控制方法。所述方法包括:在雨量采集周期T内以ΔT为时间间隔采集雨量传感器输出的雨量值,并计算每个采集点的雨量变化率;统计采集周期T内雨量变化率落在无雨阈值区间、小雨阈值区间、中雨阈值区间和大雨阈值区间的数据个数,根据落在4个区间数据个数的最大值确定当前的雨量状态,根据雨量状态控制雨刮的运动状态。本发明能够根据雨量变化率的大小准确判断雨量状态及雨量状态的跳转,从而控制雨刮以适合不同雨量状态的速度运动。
