Abstract
A method for controlling a vehicle air-conditioning system and a vehicle air-conditioning system, the method includes acquiring an actual degree of superheat, a preset degree of superheat and a degree of opening of an electronic expansion valve; determining, according to the actual degree of superheat, the preset degree of superheat and the degree of opening of the electronic expansion valve and whether the electronic expansion valve is in a fault state; and outputting a control signal to an executive control mechanism to adjust a parameter of a device in a vehicle air-conditioning system, which influences the variation of the actual degree of superheat, so as to adjust the degree of superheat of the vehicle air-conditioning system.
