The invention discloses a method for controlling the displacement of an automobile air conditioner compressor. The method comprises the steps of starting a compressor condition; presetting an automobile exterior temperature threshold value A; presetting an evaporator temperature threshold value B; enabling an engine to operate, and switching on an air conditioner compressor switch; S1, judging whether the vehicle speed is 0 or not; S2, judging whether the pressing degree of an accelerator pedal exceeds a limit value or not; S3, judging whether the vehicle speed is constant or not; S4, when thevehicle speed is greater than or equal to 60 km/h and the opening degree of the accelerator pedal is increased by greater than or equal to 20% within one second, immediately reducing the displacementof the compressor to the minimum displacement, and then executing a compressor slow starting program; and when the vehicle speed is greater than or equal to 60 km/h and the opening degree of the accelerator pedal is 0%, starting braking while and a brake switch acts, and increasing the current displacement of the compressor to the maximum displacement. According to the invention, the displacementof the automobile air conditioner compressor can be adjusted in time according to the automobile driving road condition and the automobile speed, the torque generated by the automobile engine is reduced, the service life of the device is prolonged, and the actual use requirement is met.

    本发明公开了一种汽车空调压缩机排量控制方法:开启压缩机条件:预先设定车外温度阀值A:预先设定蒸发器温度阀值B;发动机运转,接通空调压缩机开关:S1:判断车速是否为0;S2:判断油门踏板的下压程度是否超过限值;S3:判断车速是否为匀速;S4:当车速≥60km/h,在1秒内油门踏板开度量增加≥20%时,则压缩机立刻降低至最小排量,然后执行压缩机缓启动程序;当车速≥60km/h,油门踏板开度量为0%时,刹车开关动作时,则刹车制动开始,压缩机由当前排量增加到最大排量。本发明能够根据车辆行驶路况和车速适时调整汽车空调压缩机的排量,减缓汽车发动机发生的扭矩,延长了装置的使用寿命,满足实际使用要求。
