The invention discloses a control method for the running state of an air conditioner compressor and a vehicle. The method comprises the steps that an evaporator surface temperature signal is obtained; controlling a compressor to start or stop according to the evaporator surface temperature signal; when the compressor is started, a pressure feedback signal is obtained, and the pressure condition of the compressor is determined according to the pressure feedback signal; when the pressure of the compressor is normal, a current room temperature signal and a current state signal of the air conditioner are obtained; according to the current room temperature signal and the current state signal of the air conditioner, the running temperature of a compressor is determined; according to the current room temperature signal, the operation time of the compressor is determined; and according to the current room temperature signal and the operation temperature and the operation time of the compressor, an engine idle speed increasing request is determined to guarantee that the operation state of the compressor is stable. By means of the method, accurate control over the running state of the compressor is achieved.
