The invention discloses a vehicle defrosting and demisting method and device. The method comprises the steps that after an automatic defrosting and demisting function is started, a shielding area and shielding objects (at least one of frost and fog) of a front windshield are determined based on first light data and second light data of the lower portion and the upper portion of a main view area of a driver on the front windshield; when the sheltering object comprises frost, target working parameters of the air conditioning system are determined based on the sheltering area; if not, the position (one of the inner side and the outer side) of a shelter on the front windshield is determined based on the current temperature parameter and the current humidity parameter inside and outside the vehicle, and the target working parameters of the air conditioning system are determined based on the sheltering area and the position of the shelter; and the air conditioning system is controlled to work according to the target working parameters so as to remove shelters on the front windshield. According to the method and the device, the appropriate working parameters can be automatically selected to quickly defrost and demist, a user does not feel uncomfortable, the trouble of repeated manual adjustment of the user can be avoided, and the driving safety is improved.

    本申请公开了一种车辆除霜除雾方法和装置,该方法可在自动除霜除雾功能被开启后,基于前挡风玻璃上驾驶员主要视野区域下部和上部的第一光线数据和第二光线数据,确定前挡风玻璃的遮挡区域和遮挡物(霜和雾中的至少一种);当遮挡物包括霜时,基于遮挡区域确定空调系统的目标工作参数;不包括时,基于车内外的当前温度参数和当前湿度参数,确定前挡风玻璃上的遮挡物位置(内侧和外侧中的一种),基于遮挡区域和遮挡物位置确定空调系统的目标工作参数;控制空调系统按目标工作参数工作,以清除前挡风玻璃上的遮挡物。该方法和装置,可自动选择合适工作参数快速除霜除雾,不会使用户感到不适,还可免去用户反复手动调节的麻烦,提高了行车安全。
