Abstract

The invention relates to the technical field of vehicles, in particular to a control method of a vehicle air conditioning system and a vehicle, and aims to solve the problems that whether diet exists in a refrigerating chamber or not, the refrigerating function is always in an on state, electric energy waste is caused by the fact that the refrigerating function is started when diet does not exist in the refrigerating chamber, and a user is inconvenient to use if the refrigerating function is started. To this end, the air conditioning system control method of the present invention includes determining whether a vehicle is in a start state, comparing the temperature in the vehicle with a preset temperature, and judging whether food exists in a refrigerating chamber. Through driving air conditioning system and parking air conditioning system's setting, no matter the vehicle is in the state of traveling or parking all can be based on the interior temperature of car and the size of predetermineeing the temperature and whether there is the result of judging of food in the fridge, select corresponding mode, realized the intelligent regulation function of fridge indoor and interior refrigeration function, guaranteed that the user's demand is in traveling and parking in-process uninterrupted, promoted user experience.

Description

Control method of vehicle air conditioning system and vehicle Technical Field The invention relates to the technical field of vehicles, and particularly provides a vehicle air conditioning system control method and a vehicle. Background With the increasing quality of life, the more demands are placed on vehicles for having a refrigeration function, some vehicles are currently configured with a refrigeration function, such as a commercial vehicle, and the cooling refrigeration and diet refrigeration functions required by the commercial vehicle are basically provided by separate devices. Because the parking air conditioner of current vehicle provides indoor cooling refrigeration alone, and food is refrigerated then uses former car air conditioning system to realize, can't realize the continuation cold-stored of article such as diet when the parking, and in order to satisfy the cold-stored function and use then need install solitary fridge additional in the parking, occupation space has reduced space utilization, whether there is the diet in the fridge all be in the state always, the fridge function opens when there is not the diet in the fridge in addition, causes the electric energy extravagant, if turn off and need the manual shut off of user, use inconvenient, user experience degree is poor. Accordingly, the present invention is directed to a new vehicle air conditioning system control method and a vehicle for solving the above-mentioned problems. Disclosure of Invention The invention aims to solve the technical problems that the parking air conditioner of the existing vehicle independently provides indoor cooling and refrigerating, the food refrigeration is realized by using an original vehicle air conditioning system, continuous refrigeration of food and other articles cannot be realized during parking, an independent refrigerator is required to be additionally arranged for meeting the requirements of the refrigeration function when the vehicle is parked, the space utilization is reduced, whether the food refrigeration function is in an on state or not in the refrigeration chamber is always in an on state, the electric energy waste is caused by the fact that the refrigeration function is on when the food is not in the refrigeration chamber, and the problems of inconvenient use and poor user experience degree are solved if the user is required to manually turn off the vehicle. To this end, in a first aspect, the present invention provides a vehicle air conditioning system control method in which a refrigerating compartment is provided in a vehicle, the air conditioning system including a traveling air conditioning system and a parking air conditioning system, the air conditioning system control method comprising: determining whether the vehicle is in a start state; comparing the temperature in the vehicle with the preset temperature; Judging whether food exists in the refrigerating chamber or not; If the vehicle is in a starting state, selectively controlling the driving air conditioning system to execute one mode of a single air refrigerating mode, a single refrigerating mode, an air refrigerating and refrigerating double-on mode and a closing mode according to the temperature in the vehicle, the preset temperature and the judging result of whether food exists in the refrigerating chamber; and if the vehicle is in a parking state, selectively controlling the parking air conditioning system to execute one mode of a single air cooling mode, a single refrigeration cooling mode, an air refrigeration cooling double-on mode and a closing mode according to the temperature in the vehicle, the preset temperature and the judging result of whether food exists in the refrigerating chamber. Under the condition of adopting the technical scheme, through the setting of driving air conditioning system and parking air conditioning system, whether the vehicle is in the driving state or the parking state can be based on the temperature in the vehicle and the size of preset temperature and whether there is the result of judging of food in the cold storage chamber, select corresponding mode, realized the intelligent regulation function of the interior and the interior refrigeration function of cold storage chamber, guaranteed that the user demand is uninterrupted in driving and parking process, promoted user's use experience and vehicle life happiness. In a specific embodiment of the foregoing vehicle air conditioning system control method, the step of selectively controlling the vehicle air conditioning system to execute one of a single air cooling mode, a single refrigeration cooling mode, an air refrigeration cooling double-on mode and a closing mode according to a temperature in the vehicle, a preset temperature, and a determination result of whether food exists in the refrigerating chamber specifically includes: If the temperature in the vehicle is higher than the preset temperature and no food exists in the refrigeratin
