Vehicle air conditioning remote control system, server, and portable terminal

The invention provides a vehicle air conditioning remote control system, a server, and a portable terminal. A portable terminal (300) transmits to a server (210) a request to start pre-air conditioning when the operations to begin pre-air conditioning are performed on the screen of the portable terminal (300). The server (210) predicts whether an air conditioning device (180) will begin cooling or heating on the basis of a set of vehicle location information stored in a vehicle information storage unit (214) and a set of temperature information acquired from a temperature information center, and transmits the prediction results to the portable terminal (300). As a consequence, it is possible to notify the cooling and heating state to a vehicle user in a timely manner.
