Abstract
A method of preventing air pollution in a vehicle is disclosed. Firstly, an out-car gas detection device, an in-car gas detection device and a purification device are provided to detect the air pollution and transmit a respective gas detection datum to a connection device. An in-car gas exchange system is provided for intelligently selecting and controlling a gas outside the vehicle to be introduced or not introduced into the inner space of the vehicle. The connection device receives and compares the gas detection data, so that the connection device selectively transmits a control instruction to the in-car gas exchange system and the purification device, and the air pollution in the inner space of the vehicle is exchanged and filtered, so as to provide clean, safe and breathable air.
