The invention provides a vehicle-mounted air conditioner anomaly detection method and device, electronic equipment, a vehicle and a medium, and relates to the technical field of artificial intelligence, in particular to the automatic driving technology, intelligent traffic and an intelligent cabin. The method comprises the steps that the superheat degree is determined based on the low-pressure side refrigerant pressure and the evaporator outlet temperature of the vehicle-mounted air conditioner; determining a superheat degree influence factor corresponding to the environment temperature, wherein the superheat degree influence factor is in negative correlation with the environment temperature; correcting the actual air volume of the blower by using the superheat influence factor to obtain the equivalent air volume of the blower; based on the vehicle speed and the actual air volume of the cooling fan, the equivalent air volume of the cooling fan is determined; a superheat degree threshold value corresponding to the combination of the equivalent air volume of the air blower and the equivalent air volume of the cooling fan is determined; and whether the vehicle-mounted air conditioner is abnormal or not is judged through the superheat degree and the superheat degree threshold value.
