The invention discloses a windscreen wiper downshift protection method based on load identification, which is characterized in that the working load of a windscreen wiper is identified by comparing the duty ratio of a motor for driving the windscreen wiper in the working process of the windscreen wiper with a pre-calibrated limit value, so that the windscreen wiper can adapt to various working conditions, and the wiping frequency is intelligently adjusted; the purposes of protecting a wiper system (preventing the temperature of a wiper motor from being too high and preventing a wiper blade from being damaged due to long-time dry scraping when the load is too large) and saving energy and reducing consumption are achieved. The method can be used for various types of automobile windscreen wipers with drive control.

    本发明公开了一种基于负载识别的雨刮降档保护方法,通过雨刮工作过程中驱动雨刮电机占空比的大小与预先标定的限值进行对比来识别雨刮的工作负载大小,使雨刮能够适应各种工况,智能调整刮刷频率,起到保护雨刮系统(防止负载过大时雨刮电机温度过高和长时间干刮损坏刮片)和达到节能降耗的目的。可以使用于各种类型的带驱动控制的汽车雨刮器。
