该控制器采集汽车进气歧管压力传感器(MAP传感器)的输出数据,经过单片机处理,控制汽车压缩机的断开与接通,实现了在汽车起步、急加速和爬坡时自动断开压缩机负荷,消除了这些情形下空调对动力的影响.由于利用了原车传感器,故成本低廉、电路简单.并且断开压缩机负荷的延时时长、介入灵敏度可调.经过多种不同车型车主的实际使用,基本不再感受到空调对汽车动力的影响.%By processing of the MAP sensor 's output data collected by MCU,The controller can make the compressor is turned on and off ,and eliminate the influence of compressor for car's power. Due to the use of the original car sensor, the controller has the advantages of low cost,simple circuit. It has a adjustable delay-time and adjustable sensitivity. When drive the car installed the contoller,those driver no longer feel the impact of air conditioner on the vehicle's power.
