As shown in FIG. 1, an automatic parking system having an object recognition function according to the present invention includes a sensing unit 100, a control unit 200, and a monitoring unit 300.

First, the sensing unit 100 is installed on both sides of the vehicle 10, and senses an object 20 existing in the both side detection areas S of the vehicle 10.

Here, the sensing unit 100 can selectively use infrared rays, ultrasonic sensors, and the like, and can instantaneously detect an object in the detection area S in an ON state.

As shown in FIG. 2, the sensing unit 100 senses various objects 20 located in both side detection areas S of the vehicle 10.

That is, the sensing unit 100 can sense the object 20 regardless of the surrounding brightness or field of view, and can accurately detect the presence or absence of the object in a situation in which it is difficult to secure a field of view such as nighttime and bad weather conditions .

Various outline pattern information on the objects 20 are preset in the control unit 200 in advance.

Here, the pattern information stored in the controller 200 may be preliminarily set in the form of a surrounding vehicle, a column (square, circle, etc.), a person, and a bicycle.

When the sensing unit 100 receives the sensing signal of the object 20, the controller 200 analyzes the contour pattern of the sensed object 20.

At this time, the contour pattern of the object 20 refers to the surface shape of the object viewed from the sensing direction of the sensing unit 100.
