Please continue to refer to FIG. 1 and FIG. 2, in one embodiment of the present invention, the process of the air conditioning control method based on the vehicle central control specifically includes:

The communication information between the central control device 10 and the air conditioner controller 20 is acquired, and it is determined whether the central control device 10 crashes according to the communication information. When the central control device 10 crashes, the large central control screen of the central control device 10 will be in a black screen or in an inoperable state. At this time, the air conditioning system cannot be controlled on the central control device 10 of the vehicle, which may cause fogging of the windows. sex.

The communication information monitor 30 monitors the communication information between the central control device 10 and the air-conditioning controller 20 specifically includes: monitoring the communication signal value between the central control device 10 and the air-conditioning controller 20, when the communication signal value is 1, it means Normal communication between the air conditioner controller 20 and the central control device 10; when the communication value is 0, it means that the central control device 10 is in a dead state.

When it is determined that the central control device 10 is in a dead state, the air conditioning controller 20 determines whether the humidity in the vehicle reaches the fogging threshold. The humidity sensor 41 is installed in the vehicle, and the air conditioning controller 20 obtains the humidity in the vehicle through the humidity sensor 41 connected thereto and determines whether the humidity in the vehicle reaches the fogging threshold.

When it is determined by the air conditioner controller 20 that the humidity in the vehicle reaches the fogging threshold, it is then determined whether the air conditioner is on before the central control device 10 crashes. The air conditioner is then controlled by the air conditioner controller 20 to enter the anti-fogging mode. When the central control device 10 is in a shutdown state and the humidity in the vehicle does not reach the fogging threshold, the air conditioner controller 20 controls the air conditioner to maintain the air conditioner parameters before the shutdown.

In this embodiment, the first preset value is greater than or equal to 16 degrees Celsius or less than or equal to 20 degrees Celsius, and the first preset value is preferably 18 degrees Celsius.

When the air conditioner is in the first defogging mode, the external circulation damper 62 is controlled to open so that the air conditioner is in an external circulation state, the compressor 43 is controlled to be on, and the air conditioner is controlled to be in the foot blowing/defrosting mode, that is, the foot blowing damper 52 is defrosted. The frost dampers 53 are both open. This is because, when the outdoor temperature is lower than the first preset value, it is usually at a time when the temperature is low (spring, autumn or winter), and the air blowing mode of the air conditioner is not suitable for blowing the air directly to the occupant's face. Therefore, when the air conditioner is in the In the first defogging mode, controlling the air conditioner to be in the blowing mode of foot blowing/defrosting can not only achieve the defrosting effect, but also improve the comfort of the occupants.

In addition, when the air conditioner is in the first defogging mode, the temperature of the air conditioner is controlled to be at a second preset value. In this embodiment, the second preset value is greater than or equal to 20 degrees Celsius or less than or equal to 24 degrees Celsius, and the first preset value is preferably 22 degrees Celsius.

In other embodiments, when the air conditioner is in the first defogging mode, in order to reduce power, the air conditioner may also be controlled to be in a defrosting blowing mode, that is, the foot blower damper 52 may be closed.

When the air conditioner is in the second defogging mode, the external circulation damper 62 is controlled to open so that the air conditioner is in the external circulation state, the compressor 43 is controlled to be in the open state, and the air conditioner is controlled to be in the air blowing/defrosting mode, that is, the air blowing damper 51 follows the defrosting mode. The frost dampers 53 are both open. This is because, when the outdoor temperature is above the first preset value, it is usually at a relatively high temperature (usually in summer). At this time, if the air blowing mode of the air conditioner is blowing towards the occupant's face, the occupant will feel a cool breeze. Thereby enhancing comfort. Therefore, when the air conditioner is in the second defogging mode, controlling the air conditioner to be in the face blowing/defrosting blowing mode can not only achieve the defrosting effect, but also improve the comfort of the occupants.

In addition, when the air conditioner is in the second defogging mode, the temperature of the air conditioner is controlled to be at a second preset value. In this embodiment, the second preset value is greater than or equal to 20 degrees Celsius or less than or equal to 24 degrees Celsius, and the first preset value is preferably 22 degrees Celsius.

In other embodiments, when the air conditioner is in the second defogging mode, the air conditioner can also be controlled to be in a defrosting blowing mode, that is, the surface blower door 51 can be closed.
