An apparatus which determines a kind of an object to warn a driver based on the kind of the object and properly performs deceleration and braking operations based on a position of the object and a speed of the vehicle is disclosed. An infrared-ray camera is employed to detect a shape and a temperature of the object. A digital signal processing technique is utilized for displaying the temperature distribution of the object. Therefore, using the apparatus, it is able to distinguish the shape and the kind of the object in the night time and the vehicle is suitably decelerated and/or stopped based on conditions.
