In the economy mode, the percentage of the gas in the vehicle used when the vehicle-mounted air conditioning equipment adjusts the temperature is larger than or equal to the set value. The setting threshold value can be flexibly set according to actual conditions. For example, the set threshold includes 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%,

Optionally, in the economy mode, the percentage of the gas in the vehicle used when the vehicle-mounted air conditioning equipment adjusts the temperature is 90% -100%.

Therefore, when the vehicle-mounted air conditioning equipment adjusts the temperature, the temperature of the air in the vehicle can be adjusted as much as possible, the participation of the outside air is reduced, the temperature difference of the air before and after the temperature adjustment is reduced, the energy consumption of the vehicle can be reduced, and the cruising mileage of the vehicle is improved.

The economic mode may be set according to actual needs. For example, the economy mode includes an automatic mode. When the vehicle air conditioning equipment enters the automatic mode, the control method can regulate the temperature by using the gas in the vehicle as much as possible, so that the participation of the external air is reduced, the temperature difference between the gas before and after the temperature regulation is reduced, the energy consumption of the vehicle can be reduced, and the endurance mileage of the vehicle is improved.

In this way, in the economic mode that the percentage of the gas in the vehicle used when the temperature of the vehicle-mounted air conditioning equipment is regulated is greater than or equal to the set value, a proper amount of the gas outside the vehicle can be inhaled by the third air inlet part to be conveyed into the passenger cabin, so that the content of the target gas is regulated, and the content of the target gas in the passenger cabin is smaller than a first threshold value, so that the gas breathing requirement in the vehicle is ensured.

It should be noted that the first setting time may be flexibly set according to the actual situation. For example, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, and so forth.

As shown in fig. 7, in some embodiments, after the third air intake portion is made to communicate with the outside of the vehicle while maintaining the economy mode, further comprising: and when the second set time is reached and the target gas content in the passenger cabin is greater than or equal to the first threshold value, exiting the economic mode, so that the second air inlet part is not communicated with the passenger cabin. Therefore, the air quality in the passenger cabin can be improved by fully utilizing the external air of the vehicle, so that the driving experience is ensured.

In addition, the vehicle air conditioning system enters the economy mode again when the air quality in the passenger compartment is satisfactory. Therefore, the energy consumption of the vehicle can be reduced, and the continuous voyage mileage of the vehicle can be improved.

It should be noted that the second setting time may be flexibly set according to the actual situation. For example, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, and so forth.

On the basis of any of the above embodiments, as shown in fig. 7, in some embodiments, the control method further includes: when the third set time is reached and the content of the target gas in the passenger cabin is smaller than or equal to a second threshold value, the adsorption device does not adsorb the target gas; wherein the second threshold is less than the first threshold. Therefore, when the third set time is reached, the adsorption device is used for enabling the content of the target gas in the passenger cabin to be smaller than or equal to the second threshold value, so that the adsorption device is disconnected and is not used for adsorbing the target gas, and the service life of the adsorption device is prolonged.

It should be noted that the third setting time may be flexibly set according to the actual situation. For example, 5 minutes, 10 minutes, 15 minutes, 20 minutes, 25 minutes, 30 minutes, and so forth.

In some embodiments, the first set time is equal to the third set time.

The air quality in the passenger cabin can be set according to actual requirements. For example, the air quality compliance within the passenger compartment includes the target gas content being less than or equal to the second threshold.

It should be noted that specific parameters of the first threshold and the second threshold may be flexibly set according to the target gas. For example, the first threshold includes a carbon dioxide content threshold that would be trapped by an occupant, and the second threshold includes a carbon dioxide content that would not be trapped by an occupant. And/or the first threshold comprises a critical value for a harmful gas content that is harmful to the health of the occupants, and the second threshold comprises a harmful gas content that is not harmful to the health of the occupants. And/or the first threshold comprises a critical value for the moisture content of the vehicle light transmissive member to fog, and the second threshold comprises a moisture content that does not fog the vehicle light transmissive member.

In addition, it is understood that the first threshold and the second threshold may be dynamically adjusted according to conditions such as temperature in the passenger compartment.

In some embodiments, the target gas comprises carbon dioxide and the first threshold comprises a carbon dioxide content of 1000pp. Therefore, the carbon dioxide content in the passenger cabin is monitored through the gas detection device, and when the carbon dioxide content in the passenger cabin is larger than or equal to a first threshold value, the adsorption device is controlled to adsorb carbon dioxide so as to reduce the carbon dioxide content in the passenger cabin, and the situation that the riding comfort is reduced due to the fact that the carbon dioxide content is higher than 1000pp for a long time is avoided, and even the driving safety is influenced due to the fact that the driver is trapped is caused. In the process, when the vehicle-mounted air conditioning equipment adjusts the temperature, the temperature of the air in the vehicle can be adjusted as much as possible, the participation of the outside air is reduced, the temperature difference of the air before and after the temperature adjustment is reduced, the energy consumption of the vehicle can be reduced, and the cruising mileage of the vehicle is improved.

In some embodiments, the target gas comprises a harmful gas and the first threshold comprises a harmful gas content of 5mg/m ³ . In this way, the harmful gas content in the passenger cabin is monitored by the gas detection device, and when the harmful gas content in the passenger cabin is greater than or equal to the first threshold value, the adsorption device is controlled to adsorb the harmful gas so as to reduce the harmful gas content in the passenger cabin and avoid that the harmful gas content is higher than 5mg/m for a long time ³ While reducing the health of the occupant. In the process, when the vehicle-mounted air conditioning equipment adjusts the temperature, the temperature of the air in the vehicle can be adjusted as much as possible, the participation of the outside air is reduced, the temperature difference of the air before and after the temperature adjustment is reduced, the energy consumption of the vehicle can be reduced, and the cruising mileage of the vehicle is improved.
