The embodiment of the invention provides a windscreen wiper control method and device for an electric vehicle. The method comprises the steps of shooting a first image of a windscreen through a camera device of a user vehicle, and obtaining the external brightness in the first image; performing gray processing on the first image to obtain fuzzy pixels in the first image; obtaining the pixel standard of the windshield according to the external brightness, and comparing the number of the pixel points of the fuzzy pixels with the number of the pixel points of the pixel standard; when the number of the pixel points of the fuzzy pixels is greater than the number of the pixel points of the pixel standard, obtaining the difference of the number of the pixel points; and controlling a windscreen wiper of the user vehicle to brush the windshield, obtaining a corresponding windscreen wiper cleaning standard, and controlling the brushing frequency and the brushing strength of the windscreen wiper according to the pixel point number difference and the windscreen wiper cleaning standard. By means of the method, automatic scrubbing of the windshield can be completed in the driving process, the scrubbing frequency and force can be adjusted according to the fuzzy degree of the windshield, and the driving experience and safety of a user are improved.
本发明实施例提供一种电动汽车的雨刮器控制方法及装置,所述方法包括:通过用户车辆的摄像装置拍摄挡风玻璃的第一图像,并获取第一图像中的外界亮度;对第一图像进行灰度处理,得到其中的模糊像素;根据外界亮度获取挡风玻璃的像素标准,将模糊像素的像素点数与像素标准的像素点数进行对比;当模糊像素的像素点数大于像素标准的像素点数,得到像素点数差;控制用户车辆的雨刮器对挡风玻璃进行刷洗,并获取对应的雨刮器清洗标准,通过像素点数差和雨刮器清洗标准控制雨刮器的刷洗频率和刷洗力度。采用本方法能够根据在行车过程完成对挡风玻璃的自动刷洗,并且能够根据挡风玻璃的模糊程度调节刷洗的频率和力度,提高了用户的驾驶体验和安全性。
