As shown in FIG. 1 , it is determined whether to enable the first heating and defrosting mode, and if so, the step of enabling the first heating and defrosting mode, that is, step S101 includes:

Determine whether a user's instruction to turn on the first heating and defrosting mode is received, and if so, turn on the first heating and defrosting mode; or

The first temperature is preset, and it is determined whether the indoor temperature of the vehicle is lower than the first temperature, and whether the front windshield of the vehicle needs to be defrosted, if both are yes, the first heating and defrosting mode is turned on.

In this embodiment, it is exemplified that the "first temperature" is understood as a temperature at which the user feels cold and uncomfortable.

The vehicle user can control the in-vehicle air conditioning system and issue an instruction to turn on the first heating mode, such as pressing a button or operating on the touch screen. hot mode. It can be understood that, the above steps can be completed by relying on the user's subjective judgment. At this time, the user can define the specific value of the first temperature by himself according to his actual needs.

In the above, step S101 is performed by the control system. For example, the control system includes a temperature sensor, an image acquisition module, a storage module and a judgment module, wherein the temperature sensor is used to collect the real-time temperature of the front row of the vehicle, the image acquisition module is used to collect the real-time image of the front windshield of the vehicle, and the storage The module is used to store the standard image of the front windshield of the vehicle that does not need to be defogged. The judgment module is used to receive the real-time temperature sent by the temperature sensor, the real-time image sent by the image acquisition module, and the standard image sent by the storage module, and used to judge the real-time temperature. Whether the temperature is lower than the first temperature and whether the real-time image is consistent with the standard image. It can be understood that if the real-time image is inconsistent with the standard image, it is determined that the front windshield of the vehicle needs to be defrosted; otherwise, it is determined that the front windshield of the vehicle does not need to be defrosted.

As shown in FIG. 1 , it is determined whether to enable the second heating and defrosting mode, and if so, the step of enabling the second heating and defrosting mode, that is, step S102 includes:

Determine whether a user's instruction to turn on the second heating and defrosting mode is received, and if so, turn on the second heating and defrosting mode; or

The second temperature is preset, and it is determined whether the indoor temperature of the vehicle is raised from the first temperature to the second temperature, and whether the front windshield of the vehicle needs to be defrosted.

In this embodiment, it is exemplified that the temperature value of the "second temperature" is greater than the "first temperature", which can be understood as the temperature of the front row of the vehicle has gradually increased to a temperature that the user feels warmer and more comfortable .

When the front row of the vehicle warms up to the second temperature, the vehicle user can control the in-vehicle air-conditioning system and issue an instruction to turn on the second heating mode, such as pressing a button or operating on the touch screen, and the air-conditioning system receives the turn on the first heating mode. The second heating mode command controls the air conditioner to enter the second heating mode. It can be understood that, the above steps can still be completed by relying on the user's subjective judgment. At this time, the user can also define the specific value of the second temperature by himself according to his actual needs.

In the above, step S102 can also be completed by the control system.

As shown in FIG. 1 , it is determined whether to enable the defrost mode, and if so, the step of enabling the defrost mode, that is, step S103 includes:

Determine whether a user's instruction to turn on the defrost mode is received, and if so, turn on the defrost mode; or

A third temperature is preset, it is determined whether the indoor temperature of the vehicle has risen to the third temperature, and whether the front windshield of the vehicle needs to be defrosted, if both are yes, the defrosting mode is turned on.

In this embodiment, it is exemplified that the temperature value of the "third temperature" is greater than the "second temperature", which can be understood as the temperature of the front row of the vehicle at this time, which is helpful for the user to maintain body temperature for a long time. The difference between the defrost mode and the first heating defrost mode and the second defrost mode can be understood as, in the defrost mode, the heat flow prepared by the vehicle air conditioner is only used to defrost the front windshield of the vehicle, It is not used to heat the front row of the vehicle.

More specifically, since the user can maintain body temperature for a long time without feeling cold and discomfort at the third temperature, the user can issue an instruction to turn on the defrost mode, or the air conditioning system can be based on the indoor temperature and the front windshield. When it is judged that the defrosting mode needs to be turned on, the defrosting mode of the air conditioner is turned on. In this mode, the vehicle air conditioner heats the air flow into heat flow, and the heat flow is used to defrost the front windshield of the vehicle to further improve the defrosting effect of the vehicle air conditioner, thereby further shortening the length of the vehicle's front windshield. Defrost time-consuming purpose.

As shown in FIG. 1 , in some embodiments, it is exemplified that after the above step S101 is performed, step S103 may be directly performed without performing step S102 . In other words, in the first heating and defrosting mode, the user can directly issue an instruction to start the defrosting mode.

Specifically, when the user determines that the temperature of the front row of the car is lower than the first temperature and the front windshield of the car needs to be defrosted, the user sends an instruction to the on-board air conditioner to turn on the first heating and cooling of the on-board air conditioner. Frost mode; when the front row of the car warms up to the second temperature, the on-board air conditioner can not turn on the second defrost heating mode, until the front row of the car warms up to the third temperature, the on-board air conditioner directly turns on the defrost mode.

As shown in FIG. 1 , in some embodiments, the vehicle air conditioner also has a heating mode;

Control methods also include:

S104. When it is determined that the windshield of the vehicle does not need to be defrosted, the heating mode is turned on, wherein the air conditioner for the vehicle in the heating mode heats the air flow into heat flow and sends it to the front row of the vehicle.

In this embodiment, it is exemplified that the difference between the heating mode and the first heating defrosting mode and the second defrosting mode can be understood as: in the heating mode, the heat flow prepared by the vehicle air conditioner is only used for The front of the vehicle is heated and not used to defrost the front windshield of the vehicle.

As shown in FIG. 1 , in some embodiments, it is exemplified that the vehicle air conditioner can directly turn on the heating mode upon receiving an instruction from the user, or the first heating and defrosting mode can be turned on first, and then the heating mode can be turned on. The first heating defrosting mode and the second heating defrosting mode can be turned on successively, and then the heating mode can be turned on. Turn on heating mode.
