<p>According to a controlling method of internal and external air modes for a vehicle, a traffic jam is sensed by using a front sensor and a vehicle speed sensor. When the traffic jam is sensed, a vehicle air mode is switched from the external air mode to the internal air mode. When the traffic jam is not sensed, whether or not the vehicle enters a tunnel is sensed by using an illumination sensor. If the vehicle enters the tunnel, the vehicle air mode is switched from the external air mode to the internal air mode. Accordingly, the external or internal air mode is automatically switched according to whether the traffic is jammed or not and whether the vehicle enters the tunnel or not.</p> |
