Foreign matter purging control method and system and vehicle

According to the foreign matter purging control method and system and the vehicle, through a front purging device designed on a vehicle head and an air pressure control device designed in a vehicle body, in combination with a sensor set and a vehicle body control device, the magnitude of purging air pressure and the purging direction can be dynamically adjusted according to the vehicle speed and the vehicle turning angle; therefore, foreign matters are prevented from colliding with the vehicle head and polluting the vehicle. 本发明公开了一种异物吹扫控制方法及系统、车辆，通过设计在车头的前部吹扫装置和设计在车身中的气压控制装置，结合传感器组和车身控制装置，可根据车辆车速和车辆转弯角度动态调整吹扫气压的大小和吹扫方向，以在车头形成一道气幕，从而防止异物撞击车头而污染车辆。
