Defrosting system and defrosting method for car window

The invention provides a defrosting system and a defrosting method for a vehicle window. The defrosting system comprises a defrosting scraping plate and a damping sensor which are arranged in a door plate of a vehicle door of a vehicle; the center of the damping sensor and the center of the defrosting scraper blade are located on the same horizontal line. A controller in the vehicle is used for controlling the damping sensor to monitor the damping coefficient of the window glass in response to a received defrosting instruction issued by a user; and on the basis of the damping coefficient obtained from the damping sensor, window glass of the vehicle is controlled to conduct corresponding lifting operation, so that the window glass is defrosted through the defrosting scraper. According to the defrosting system and the defrosting method, automatic defrosting can be achieved, and therefore energy consumption and labor cost are reduced. 本申请提供了一种车窗的除霜系统和除霜方法，所述除霜系统包括：设置在车辆的车门门板内部的除霜刮板和阻尼传感器；所述阻尼传感器的中心与所述除霜刮板的中心处于同一
