Abstract

The embodiment of the invention discloses a control method, device and system of a vehicle air conditioner and a vehicle. The control method comprises the steps that parameters of the environment of the vehicle, a vehicle running parameter and air conditioner parameters set by a user are acquired; the environment parameters comprise outside temperature, inside temperature, inside humidity, outsideair quality, air conditioner water temperature and sunlight radiation strength; the vehicle running parameter comprises engine rotation speed; the air conditioner parameters set by the user comprisetarget temperature and a mode type; the working state of the air conditioner is determined according to at least one of the environment parameters, the vehicle running parameter and the air conditioner parameters; and the working state of the air conditioner comprises the state of an air door motor, the opening of an electric control water valve, the operation time of a compressor, the states of inner and outer circulation motors and the state of a blast capacity tap position. By adopting the control method, convenience for control of vehicle air conditioner can be improved, so that human bodythermal comfort requirements can be met timely by a inside-vehicle temperature field.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle air conditioners, and in particular, to a control method, device, system and vehicle of a vehicle intelligent air conditioner. Background technique [0002] Most of the existing vehicle air-conditioning systems meet the heat demand of the human body by manually operating the air-conditioning controller to adjust parameters such as the air outlet temperature, air volume, and blowing mode of the air-conditioning box. But this kind of control has two disadvantages: one is that if the driver operates the air conditioning system during driving, it will affect driving safety; The cooling and heating capacity of the load and the air conditioning system change dynamically, and this simple control of the temperature field cannot always meet the thermal comfort needs of the human body. [0003] Under the premise of low-cost control, vehicle air conditioners have not yet realized fully...
