The invention relates to a system and method for preventing inflow of exhaust gas for a vehicle. The system for preventing inflow of exhaust gas for a vehicle, may include an inside / outside air door provided in an air conditioning device of the vehicle and controlling an amount of outside air introduced into an inside of the vehicle, an outside-air temperature sensor measuring a temperature of the outside air of the vehicle, a temperature control door disposed inside the air conditioning device of the vehicle and controlling a temperature of air discharged to the inside of the vehicle, and a control unit controlling the inside / outside air door to cause an amount of the outside air to be introduced to the inside when a vehicle speed may be equal to or larger than a predetermined speed, wherein the control unit controls the temperature control door to control the temperature of the air discharged to the inside when the temperature of the outside air deviates from a predetermined temperature range.
Description
[0001] Cross References to Related Applications [0002] This application claims priority from Korean Patent Application No. 10-2012-0055782 filed May 25, 2012, the entire contents of which are hereby incorporated by reference for all purposes. technical field [0003] The present invention relates to an exhaust gas inflow prevention system and method for a vehicle, which addresses the pressure difference between the interior and exterior of the vehicle when it is driven at high speed, while controlling the temperature of the air discharged to the interior of the vehicle, by This prevents performance degradation to interior heating or cooling and keeps passengers comfortable. Background technique [0004] In general, vehicles are manufactured to prevent outside air from flowing into the interior of the vehicle. However, some air may flow in and out of the vehicle due to manufacturing tolerances or assembly constraints. In this case, if the vehicle runs at a high speed, the...
