1. A method of controlling a vehicle, the method comprising:
receiving information related to a plurality of signs of different types installed on a road;
determining whether each of the plurality of signs is related to an external temperature of the vehicle or an external wind speed of the vehicle;
calculating distance information between the plurality of the signs when all of the signs are related to the external wind speed of the vehicle;
recognizing at least one sign, from among the plurality of signs, installed on the road using a front camera;
determining a type of the at least one sign;
in a case in which the at least one sign corresponds to a road freezing sign based on referring to a memory, determining whether a temperature sensed by a temperature sensor installed outside the vehicle is a freezing danger temperature;
in a case in which the temperature sensed by the temperature sensor corresponds to the freezing danger temperature, determining whether a drive mode of the vehicle is set to a winter mode;
in a case in which the drive mode of the vehicle is not set to the winter mode, displaying a winter mode automatic switching notification message through an instrument panel; and
transmitting a command for switching to the winter mode to a drive mode controller.
