Car internal and external circulation control method and system

Abstract

The invention discloses a method and system for controlling the internal and external circulation of an automobile, which belongs to the field of automobiles and is used to automatically switch the internal and external circulation of an automobile air conditioner. The method includes: detecting gaseous pollutants in the external environment of the automobile, the gaseous pollutants include at least one of the following: carbon monoxide, nitrogen dioxide, sulfur dioxide, ammonia, hydrogen, and dust; the gaseous pollutants in the external environment of the automobile exceed a threshold , switch the car from the outer circulation state to the inner circulation state, wherein the outer circulation state is a state in which the environment inside the vehicle is connected to the environment outside the vehicle, and the inner circulation state is a state in which the environment inside the vehicle is isolated from the environment outside the vehicle. The invention is used for switching the internal and external circulation of the automobile.

Description

technical field [0001] The invention relates to the field of automobiles, in particular to a method and system for controlling internal and external cycles of automobiles. Background technique [0002] With the continuous progress of society, the development of science and technology and the improvement of living standards, especially with the accelerated development of the urbanization process, more and more cars appear around people. When people drive cars, they will encounter various pollutants, such as smog pollution, dust and various other harmful chemical gas pollution. [0003] When the vehicle travels in foggy weather or if the vehicle is driving on construction roads, bad roads or roads near chemical plants, various gas pollutants (such as smog, dust, etc.) permeated on the road will enter from the air inlet of the vehicle. to the car. The entry of these gaseous pollutants into the car will affect the health of the car members to varying degrees. At the same time...

Problems solved by technology

And when the members in the car feel the presence of peculiar smell and manually switch the internal and external circulation, often the harmful substances in the air have entered the car, causing certain injuries to the body of the members in the car, and some domestic car dampers are adjusted by mechanical cables. mode, the operating force is large, so manual switching cannot quickly and conveniently cut off the entry of harmful substances from the outside
