As shown in FIG. 1, the vehicle air conditioning system 100 using the vehicle exterior weather information of the present invention includes a receiver 10 receiving weather information transmitted from a weather information transmitter for transmitting weather information outside the vehicle. And a controller 20 that receives the weather information received from the receiver 10 and controls the air conditioner of the vehicle in response to the weather outside the vehicle.

The receiver 10 receives the weather information in real time from the weather information transmitter 11 provided outside the vehicle and transmits the weather information to the controller 20. The weather information transmitter 11 may be applied to a call center, FM DARC (Data Radio Channel), or the like. As shown in FIG. 3, the FM DARC (Data Radio Channel) method receives the weather information 13 through the DARC CENTER 15, and transmits the weather information 13 to the DARC receiver 19 mounted on the vehicle through the FM radio 17. Receive the transmission. The weather information transmitter is not limited to the call center and the FM DARC (Data Radio Channel), but can be applied in various ways to provide weather information.

The control unit 20 receives a weather information receiver 21 for receiving weather information outside the vehicle, a weather information analyzer 23 for analyzing weather information received by the weather information receiver 21, and an air conditioner of the vehicle. It is provided with an air conditioner control unit 25 to control in response to the weather.
