PURPOSE: A device for automatically controlling the heating temperature of a vehicle is provided to control the heating state of air by controlling the quantity of an engine coolant supplied to a heater core and to automatically control the temperature of the room by occasionally measuring the temperature of the air heated and supplied. CONSTITUTION: A heating apparatus of a vehicle has a duct(10) communicating with the room of the vehicle; a blowing fan(20) forcibly supplying external air through the duct; a heater core(30) disposed in the middle of the duct; and a coolant pipe(50) for supplying a coolant of an engine(40) to the heater core. A device for automatically controlling the heating temperature of the vehicle comprises a ball valve(60) installed in the middle of the coolant pipe connected to the heater core; an actuator(70) connected to a valve shaft of the ball valve; a temperature sensor(80) arranged in the heater core inside the duct; and a control part(90) receiving a temperature value sensed from the temperature sensor and controlling the actuator. The opening and shutting angle of the ball valve is varied. The actuator controls the opening and shutting angle of the ball valve.
