Description

Vehicle air quality management system, method, computer program product, and vehicle Technical Field The present invention relates to the field of vehicle technology, and in particular to a vehicle air quality management system, a vehicle air quality management method, a computer program product and a corresponding vehicle. Background With the continued increase in the amount of vehicle maintenance and the extended residence time of users in vehicles, the quality of air in vehicles has become a critical factor affecting the health and comfort of occupants. Meanwhile, the global automotive industry is accelerating the environment-friendly replacement of propellant refrigerants, and natural working medium refrigerants such as R290 (propane, C 3H8) and R744 (carbon dioxide, CO 2) become an important development direction of a new generation of vehicle air conditioning system due to zero ozone depletion potential and greenhouse effect index. R290 has excellent thermodynamic properties, but has flammable and explosive properties as a hydrocarbon, and may cause serious safety risks if not early-warned and disposed of in time once leakage occurs in the front cabin or the passenger cabin of the vehicle. While the R744 system is nontoxic and nonflammable, the working pressure is extremely high, the concentration of CO 2 in the cabin is easy to rise suddenly after leakage, and the oxygen deficiency or choking hazard is also caused to passengers. However, existing vehicle air quality management schemes are designed mainly for conventional road pollutants (such as PM2.5, NOx, etc.), rarely cover special gas concentration anomaly scenarios caused by refrigerant leakage, and especially lack corresponding emergency ventilation linkage strategies for different cabins of a vehicle when propane concentration rises rapidly. Therefore, it is highly desirable to construct a set of intelligent air quality management system for novel environment-friendly refrigerant characteristics, which can realize accurate detection, concentration evaluation and corresponding emergency response for different vehicle cabins at the early stage of refrigerant leakage, and fully ensure the life and property safety of vehicle passengers. Disclosure of Invention The object of the present invention is to provide a vehicle air quality management system, a vehicle air quality management method, a computer program product and a corresponding vehicle, which enable to solve various technical problems existing in the prior art at least partly. According to a first aspect of the present invention there is provided a vehicle air quality management system comprising: An air quality detection device configured to be adapted to detect an air quality in a front cabin and an air quality in a passenger cabin of a vehicle; A front nacelle ventilation module configured to perform a ventilation operation on the front nacelle interior; a passenger compartment ventilation module configured to perform a ventilation operation on the interior of the passenger compartment, and A control device configured to be adapted to control the operation of the front cabin ventilation module and/or the passenger cabin ventilation module based on a detection result of the air quality detection device. In one exemplary embodiment, the air quality detection device is provided at a dash panel for separating the front cabin from the passenger cabin, is configured to be at least suitable for detecting a harmful gas concentration, in particular a propane concentration, and comprises: a front nacelle gas detection passage having a gas inlet and a gas outlet both open to the front nacelle and adapted to detect the mass of air flowing through the front nacelle, and A passenger compartment gas detection channel having a gas inlet opening towards the passenger compartment and a gas outlet opening towards the front compartment and adapted to detect a mass of air from within the passenger compartment. In one exemplary embodiment, the front nacelle ventilation module includes a ventilation grille assembly configured to open its ventilation grille to communicate the front nacelle interior with an external environment, a fan disposed at the front grille and having an exhaust mode adapted to exhaust gases within the front nacelle and a cooling mode adapted to cool the front nacelle interior, and a spraying device configured to spray a mist of water into the front nacelle interior. In one exemplary embodiment, the passenger compartment ventilation module includes an air conditioning device and a window assembly. In an exemplary embodiment, the control device is configured to turn off an outer circulation function of the air conditioning device, turn on the ventilation grille, control a fan to operate in the exhaust mode, and turn on a spraying device to spray water mist when a detection result of the air quality detection device indicates that the air quality in the front cabin is not acceptable and the
