Disclosed are a
system and a method for controlling switching between an
indoor air recirculation mode and an outdoor air recirculation mode of a vehicle, including a
washer fluid spray switch, a weather information provider, a rain detection sensor that provides rainfall information, a
windshield wiper switch that provides a
windshield wiper operation level
signal, and a vehicle speed sensor. A controller receives an ON operation
signal from the
washer fluid spray switch, changes an
operation mode of an
HVAC system from the outdoor air recirculation mode to the
indoor air recirculation mode, and controls adjusting a time for returning the
indoor air recirculation mode to the outdoor air recirculation mode to be different from a reference time, on the basis of the information or signals provided from the weather information provider, the rain detection sensor, the
windshield wiper switch, and the vehicle speed sensor.
