In the embodiment, the time for controlling the advance operation time of the vehicle-mounted air conditioner is about 10-15 min, and is short, except for sudden rain or sudden temperature reduction, the radiant heat quantity of sunlight entering the vehicle in the short time period is generally considered to be almost constant, that is, the radiant heat quantity of sunlight entering the vehicle at each moment of the short time period is almost the same. Therefore, in the embodiment, the radiant heat per unit time of the sunlight entering the vehicle interior is calculated according to the vehicle interior temperature A1, the vehicle interior temperature A2, the vehicle exterior temperature B1, the vehicle exterior temperature B2 and a preset estimation formula of the vehicle interior and exterior radiant heat, and the radiant heat in unit time is taken as the radiant heat in unit time when sunlight enters the vehicle when the vehicle-mounted air conditioner runs before a driver reaches the vehicle, wherein, the radiant heat quantity when the sunlight enters the vehicle and the heat transfer quantity of the temperature difference between the inside and the outside of the vehicle can not be obviously changed in a short time, the rising rate of the temperature in the vehicle is basically unchanged in a short time and the temperature outside the vehicle is basically unchanged, for convenience of calculation, in the embodiment, the average in-vehicle temperature of the automobile in the first preset time is the average value of the in-vehicle temperature a1 and the in-vehicle temperature a2, and taking the average value of the temperature B1 outside the vehicle and the temperature B2 outside the vehicle at the average temperature outside the vehicle in the first preset time. It should be noted that, when it rains suddenly or cools down suddenly in summer, the driver may control the vehicle-mounted air conditioner to turn off through the mobile terminal.

Therefore, when a driver controls the start of the vehicle-mounted air conditioner before the vehicle arrives, the early start time of the vehicle-mounted air conditioner is reduced to the maximum extent, the later the start time of the vehicle-mounted air conditioner is, the better the start time of the vehicle-mounted air conditioner is, and the temperature in the vehicle is preferably just reduced to be close to the preset target regulation temperature when the driver just arrives at the vehicle, so that the lost refrigeration energy consumption of the vehicle-mounted air conditioner during the early operation is greatly reduced, and the preset target regulation temperature is 22-25 ℃.
In the embodiment, when the vehicle-mounted air conditioner is controlled to be started in advance, the vehicle-mounted air conditioner is operated at the preset vehicle-mounted air conditioner maximum refrigerating power, so that the time for reducing the temperature in the vehicle to the preset target regulation temperature is shortened as much as possible, the operation time of the vehicle-mounted air conditioner before the driver reaches the vehicle is calculated according to the unit time radiant heat of sunlight entering the vehicle, the temperature A2 in the vehicle, the temperature B2 outside the vehicle, the preset vehicle-mounted air conditioner maximum refrigerating power, the preset target regulation temperature and the preset vehicle-mounted air conditioner operation time estimation formula, so as to determine the time point for the vehicle-mounted air conditioner to be started in advance, wherein the external heat such as the radiant heat of the sunlight entering the vehicle and the heat transfer quantity of the temperature difference between the inside and the outside of the vehicle can not be obviously changed in a short time, and the, in the present embodiment, the average in-vehicle temperature when the vehicle air conditioner is operated in advance is an average of the in-vehicle temperature a2 and the preset target regulation temperature A3, and the average out-vehicle temperature is an out-vehicle temperature B2.
