The invention discloses a method for recovering a wiper angle after an automobile wiper encounters snow resistance, and the method comprises the following steps: when the wiper encounters the snow resistance, the wiper wipes according to a mode of firstly accelerating and then decelerating, when the wiper wipes upwards, the wiper firstly starts to accelerate at a minimum speed Vmin from a lower limit alpha 1 degree, the speed of the wiper reaches a maximum speed Vmax at a middle angle position, and then the wiper is decelerated to wipe to an upper limit beta 1 degree; at the moment, the speed of the windscreen wiper is reduced to the minimum speed Vmin; and during downward scraping, acceleration is started from the upper limit beta 1 degree at the minimum speed Vmin in the same way, the speed reaches the maximum value Vmax when the speed reaches the middle angle position, and then the speed is reduced to the lower limit alpha 1 degree, and the speed is the minimum value Vmin. When scraping and brushing are conducted in winter, the speed of impacting obstacles (ice and snow) can be reduced, then the impact strength is reduced, energy consumption and heating of the motor are reduced, and the service life of the motor can be prolonged.
本发明公开了一种汽车雨刮遇雪阻后刮角回收的方法,雨刮遇雪阻刮刷时,雨刮按照先加速再减速的方式刮刷,雨刮向上刮时先从下极限α1°处以最小速度Vmin开始加速,在中间角度位置雨刮速度达到最高速度Vmax,之后再减速刮到上极限β1°处,此时雨刮速度又降到最小速度Vmin;往下刮时同理以最小速度Vmin从上极限β1°处开始加速,到中间角度位置速度达到最大值Vmax,之后减速刮刷至下极限α1°处速度为最小值Vmin。本发明在冬季进行刮刷时可以减小撞击障碍物(冰雪)的速度,进而降低撞击力度,减少电机的能耗以及发热,可延长电机的使用寿命。
