The invention discloses a vehicle idling air conditioner control method and control system, and relates to the technical field of vehicle air conditioners. The control method comprises the steps thatthree disconnected threshold intervals of air conditioner pipeline pressure are set, and a second threshold interval is located between the high end value of a first threshold interval and the low endvalue of a third threshold interval; when the vehicle idles, the control switch of the air conditioning system is started, and the pressure of an air conditioning pipeline is collected; when the initial pressure of the air conditioner pipeline is located between the low-end value of the first threshold value interval and the high-end value of the second threshold value interval, the air conditioner compressor is controlled to work, and a fan does not work; the working pressure of the air conditioner pipeline rises from low, and when the working pressure reaches the high-end value of the second threshold value interval, the fan starts to work; and if the working pressure is reduced from high to low and reaches the low end value of the second threshold interval, the fan does not work. According to the fan, the working time of the fan is shortened, the energy consumption loss is reduced, the running state and the rotating speed of the fan are relatively stable, and the generated noise islow.

    本发明公开了一种车辆怠速空调控制方法及控制系统,涉及汽车空调技术领域,该控制方法包括:设置空调管路压力的三个不相连的阈值区间,且第二阈值区间位于第一阈值区间的高端值与第三阈值区间的低端值之间;在车辆怠速时启动空调系统的控制开关,并采集空调管路的压力;当空调管路的初始压力位于第一阈值区间的低端值与第二阈值区间的高端值之间时,控制空调压缩机工作,且风扇不工作;空调管路的工作压力由低升高,当到达第二阈值区间的高端值时,风扇开始工作;若工作压力由高降低,到达第二阈值区间的低端值时,风扇不工作。本发明,不仅减少了风扇的工作时间,减少能耗损失,且风扇运转状态及转速相对稳定,产生的噪音较小。
