Beschreibung
Zusammenfassung:	The invention discloses a vehicle air-conditioning system detection method and device; the method comprises the following steps: collecting pressure data and control signals of at least two types generated by the air-conditioning system in a cooling test process of the vehicle air-conditioning system; determining air-conditioning system pressure fluctuation indicated by the pressure data is abnormal or not; if the pressure fluctuation is abnormal, determining the cause of the abnormal pressure fluctuation of the air-conditioning system according to a switching frequency of the control signals of different types. The method and device can solve the technical problems that the reasons causing the pressure fluctuation abnormity cannot be accurately determined in the prior art, and can fast and accurately determine the reasons causing the pressure fluctuation abnormity of the air-conditioning system.
