The invention provides a control method for an air conditioner system pressure of a controller of an automobile motor compressor. An actual pressure valve in the air conditioner system is acquired through the calculation between a ratio of a power output to a the motor compressor and a feedback actual speed of the motor compressor and a standard curve obtained through early experimental calibration of a ratio and a speed ratio, the actual speed value of the air conditioner system is acquired, and the actual speed value is compared with a standard pressure value, so that the output voltage and output current of the controller are adjusted, and the pressure balance in the air conditioner system is guaranteed. According to the control method for the air conditioner system pressure of the controller of the automobile motor compressor, the defect in the prior art is overcome, the output voltage and output current of the controller of the motor compressor are revised dynamically through closed loop feedback control, and the pressure in the air conditioner system reach a constant value; the control method is convenient and accurate, an expressive pressure sensor is not needed to buy at the same time, the pressure of the air conditioner system can be constant to different pressure states according to different working conditions, and the cost is saved greatly.
