The invention discloses a defrosting and anti-fogging control method for an air conditioner of a new energy vehicle. The defrosting and anti-fogging control method comprises the following steps that S1, a humidity value H of front windshield glass is collected through an anti-fogging sensor; S2, whether the current humidity value H is larger than 50% or not is judged, if so, S3 is executed, and ifnot, the S1 is executed again; S3, an automatic defrosting action is executed, the outer circulation opening degree is made to reach 80%, a foot blowing/defrosting mode is started, and the duration is deltaT; S4, whether the current humidity value H is smaller than 50% or not is judged, if so, S5 is executed, and if not, the S3 is executed again; and S5, the working state before automatic defrosting is recovered. Defrosting and anti-fogging control logic is formulated through a winter real vehicle calibration test.

    本发明公开了一种新能源车空调除霜及防结雾控制方法,包括以下步骤:步骤S1:通过防雾传感器采集前风挡玻璃的湿度值H;步骤S2:判断当前湿度值H是否大于50%,若是,则执行S3,若否则返回步骤S1;步骤S3:执行自动除霜动作,将外循环开度到80%,进入吹脚/除霜模式,持续时长△T;步骤S4:判断当前湿度值H是否小于50%,若是,则执行S5,若否则返回步骤S3;步骤S5:恢复到自动除霜之前的工作状态。本发明通过冬季实车标定测试,制定除霜及防结雾控制逻辑。
