OPTIMAL ROOM TEMPERATURE CONTROL METHOD FOR VEHICLE

PURPOSE: An optimal room temperature control method for a vehicle is provided to keep the room environment of the vehicle pleasant by controlling room temperature according to the external environmental changes of seasons. CONSTITUTION: An optimal room temperature control method for a vehicle is composed of steps for sensing the room temperature in the vehicle and a set temperature set by users(S100,S200); judging whether the room needs to be warmed up or cooled down(S300); detecting the difference between a sensible temperature that drivers feel and the room temperature from a storage data(S400,S450); setting a target room temperature(S500,S550); controlling warming or cooling mode(S700,S750); and repeatedly detecting room conditions of the vehicle to remove difference between the room temperature and the sensible temperature and stopping room temperature controlling when the room conditions are in a target range(S800).
