METHOD FOR CONDITIONAL NATURAL VENTILATION OF VEHICLE INTERIOR AND VEHICLE THEREBY

The present invention provides a method for conditional natural ventilation of a vehicle interior and a vehicle thereof. The method for natural ventilation of a vehicle interior includes steps of: determining, by a controller, formation of an interior negative pressure in an interior space while driving of a vehicle is maintained as an internal air mode, determining, by the controller, an over-production of a harmful gas in an exhaust gas using an air-to-fuel ratio or an Accelerator Position Scope (APS), in an air conditioning system; regarding satisfaction of the formation of the interior negative pressure and satisfaction of the over-production of the harmful gas as an entry condition and mixing an exterior air into the interior space so as to mitigate the interior negative pressure in the internal air mode; and after mixing the exterior air, regarding the non-satisfaction of the over-production of the harmful gas as a cancellation condition and blocking the exterior air. 种用于车辆内部有条件的自然通风方法及其车辆，该方法包括以下步骤：在行驶
