The embodiment of the invention provides a control method and device of a vehicle-mounted air conditioner, a vehicle-mounted air conditioner system and a vehicle. The control method of the vehicle-mounted air conditioner comprises the steps that a current target air suction capacity control signal is determined according to a current initial air suction capacity control signal and a current variable control signal; according to the current target air suction capacity control signal, the current ideal air suction capacity of the compressor is determined; the compressor is driven to work according to the current target air suction capacity control signal, and the current actual air suction capacity of the compressor is obtained; a current air suction capacity difference value between the current actual air suction capacity and the current ideal air suction capacity is determined; and if the current air suction capacity difference value does not belong to the error value interval, a new variable control signal is at least obtained and then the next control cycle is started until the current air air suction capacity difference value belongs to the error value interval. The precision of the air suction capacity of the compressor can be improved, the heating and refrigerating efficiency of the air conditioner can be effectively improved, and the occurrence probability of accidents such as fire can be greatly reduced.
Description
technical field [0001] The present application relates to the technical field of new energy vehicles. Specifically, the present application relates to a control method and device for a vehicle air conditioner, a vehicle air conditioner system and a vehicle. Background technique [0002] At present, when the vehicle-mounted air conditioner is running, there will be a certain fluctuation error in the suction volume of the compressor, which will reduce the accuracy of the suction volume and cause some adverse effects. For example, if the suction capacity of the compressor is too low, the temperature or pressure in the compression chamber will be too high, which will easily cause accidents such as fire; if the suction volume of the compressor is too high, the pressure in the compression chamber will be insufficient, resulting in low cooling and heating efficiency . Contents of the invention [0003] Aiming at the shortcomings of the existing methods, the present application p...
