The invention discloses a defogging method, system and device for a windshield of a front view module of a vehicle, and the method comprises the steps: calculating the reduction amplitude of the image definition when the image definition collected by the front view module is reduced; when the decreasing amplitude is larger than or equal to the starting threshold value, the heating pipe is started to heat air in the flow guide pipeline, and the air in the flow guide pipeline is guided into the cavity through the air inlet fan; wherein the cavity is formed by the foresight support baffle between the foresight module and the windshield, the connecting position of the foresight support baffle and the windshield is closed, and air in the cavity is led out of the cavity through the air outlet fan; when the image definition is greater than or equal to a closing threshold value, judging whether the heating time is less than the minimum heating duration or not; if yes, the air in the flow guide pipeline continues to be heated through the heating pipe; if not, the heating pipe is closed. The defogging efficiency of the windshield at the front end of the foresight module is improved.
本申请公开一种车辆前视模组的挡风玻璃除雾方法、系统及装置,方法包括:当前视模组采集的图像清晰度下降时,计算图像清晰度的下降幅度;当下降幅度大于或等于启动阈值时,启动加热管加热导流管路中的空气,并将导流管路中的空气通过进风风扇引入空腔中;其中,空腔是由前视支架挡板在前视模组与挡风玻璃之间形成的空腔,前视支架挡板与挡风玻璃的连接位置是密闭的,空腔中的空气通过出风风扇引出空腔;当图像清晰度大于或等于关闭阈值时,判断加热时间是否小于最低加热时长;如果是,继续通过加热管加热导流管路中的空气;如果否,关闭加热管。本申请提高了前视模组前端挡风玻璃的除雾效率。
