PM2.5 control strategy outside four vehicles
PM2.5 control strategy outside the car is according to the difference of the outside temperature under the air conditioner AUTO mode, need to have different air purification strategies, PM2.5 control strategy outside the car will carry out automatic control to the air door as long as satisfy corresponding condition independent of the control strategy in the car to reduce PM2.5 outside the car to the influence in the car, and the control strategy in the car is then when PM2.5 reaches certain numerical value automatic control strategy in the car, both are different, PM2.5 strategy outside the car of this application is as follows:
i, the temperature outside the vehicle is more than 23 ℃ (summer)
And determining the internal and external circulation states according to whether the concentration value of PM2.5 outside the vehicle is greater than 115, wherein when the concentration value outside the vehicle is less than 115, the circulation damper does not act, and when the concentration value outside the vehicle is greater than 115 degrees, the circulation damper is switched to be in internal circulation. Monitoring and judging the value of outer PM2.5 every 1min in real time: when the PM2.5 outside the automobile is smaller than 115, the internal circulation air door is automatically calculated according to AUTO; when PM2.5 outside the vehicle is more than 115, the internal circulation state is kept; if the internal circulation is continuously carried out for 15min, the external circulation is switched to 1min, and then the PM2.5 value outside the vehicle is monitored and judged once per minute. The pollution to the interior of the automobile caused by the overlarge PM2.5 outside the automobile and the influence on the human body caused by the non-circulation of air such as oxygen in the automobile caused by long-time circulation are prevented, so that the ventilation needs to be switched to the external circulation after the long-time circulation.
II, the temperature outside the vehicle is more than 2 ℃ and less than 23 ℃ (spring and autumn)
And determining the internal and external circulation states according to whether the concentration value of PM2.5 outside the vehicle is greater than 115 and the A/C state, wherein when the concentration value outside the vehicle is less than 115 or the A/C state is closed, the circulation damper does not act, and when the concentration value outside the vehicle is greater than 115 degrees and the A/C state is opened, the circulation damper is switched to carry out internal circulation. Monitoring and judging the value of outer PM2.5 every 1min in real time: when the PM2.5 outside the automobile is smaller than 115, the internal circulation air door is automatically calculated according to AUTO; when PM2.5 outside the vehicle is more than 115, the internal circulation state is kept; if the internal circulation is continuously carried out for 15min, the external circulation is switched to 1min, and then the PM2.5 value outside the vehicle is monitored and judged once per minute.
III, the temperature outside the vehicle is less than 2 ℃ (winter)
The circulation damper is not affected by the PM2.5 value.
The control strategy inside and outside the automobile is triggered by different temperatures outside the automobile, the influence of the environment inside the automobile and the air conditioner on the human body is comprehensively considered, and the air conditioner control after opening the PM25 is realized, so that the demand of a user is met, the demand of PM2.5 control of the user is met, and the user experience is improved due to multiple consideration of the automatic control strategy.
It is clear that the specific implementation of the invention is not restricted to the above-described embodiments, but that various insubstantial modifications of the inventive process concept and technical solutions are within the scope of protection of the invention.
