The embodiment of the invention relates to the technical field of vehicles, and discloses a windscreen wiper control method and device and a computer readable storage medium. The method comprises the steps that piezoelectric signals within a preset time interval are collected, and the piezoelectric signals are generated by a piezoelectric sensor arranged on a vehicle body outside a vehicle; calculating a current energy value of the piezoelectric signal, and determining a suspected raining scene when the current energy value is greater than a preset energy threshold value; calculating a plurality of rainfall characteristic values in the suspected raining scene based on the piezoelectric signal, and determining the raining scene according to at least one rainfall characteristic value; the rainfall intensity in the raining scene is calculated according to the rainfall characteristic values, and the wiper motor is controlled to rotate according to the rainfall intensity. According to the technical scheme, the collected piezoelectric signals are not prone to being influenced by environmental factors, the rainfall scene can be accurately determined according to the rainfall characteristic values obtained through calculation of the piezoelectric signals, and therefore the accuracy of windscreen wiper control can be improved.

    本申请实施例涉及车辆技术领域,公开了一种雨刮控制方法、装置及计算机可读存储介质,其中方法包括:采集预设时间区间内的压电信号,压电信号由设置在车辆外车身上的压电传感器产生;计算压电信号的当前能量值,在当前能量值大于预设能量值阈值的情况下,确定为疑似下雨场景;基于压电信号计算得到疑似下雨场景下的多个降雨特征值,根据至少一个降雨特征值确定下雨场景;根据多个降雨特征值计算得到下雨场景下的降雨强度,根据降雨强度控制雨刮电机转动。应用本申请的技术方案,采集的压电信号不容易受到环境因素影响,能够根据压电信号计算得到的降雨特征值,准确确定下雨场景,从而能够提高雨刮控制的精准性。
