The present invention relates to an automatic parallel parking method of a vehicle, capable of automatically parallel parking a vehicle without intervention by a driver. An automatic parallel parking system of a vehicle comprises: a vehicle body which drives front and rear wheels by a DC motor; a steering unit coupled to the front wheel of the vehicle body which adjusts the steering direction of the vehicle body; a braking unit which brakes the movements of the vehicle body; an obstacle detecting unit which detects an obstacle on the front, lateral, and rear sides of the vehicle body; and an ECU which controls the steering unit, the braking unit, and the DC motor to automatically parallel park the vehicle body in accordance with a detection result of the obstacle detecting unit. Moreover, the obstacle detecting unit comprises front and rear infrared sensors and a plurality of lateral infrared sensors. According to the present invention, the automatic parallel parking method of a vehicle comprises the following steps: allowing the lateral infrared sensors to detect a lateral space to determine whether the vehicle body can be parked within the lateral space when the vehicle body is moved; moving the vehicle body in a forward direction until a predetermined distance is spaced apart from an obstacle in front of the detected parking space; moving the vehicle body backward into the detected parking space in a left direction up to a set backward distance; moving the vehicle body forward in a right direction up to a set front distance; moving the vehicle body backward up to the set backward distance; moving the vehicle body backward in the left direction by a predetermined distance and moving the vehicle body forward in the right direction by a predetermined distance to align the vehicle body to a lateral surface; and braking the vehicle body when the vehicle body moves backward up to the set backward distance to be placed at the center of the parking space.

    본 발명은 차량 자동평행주차방법에 관한 것으로서, 상기 차량의 자동평행주차시스템은, DC모터에 의해 전륜과 후륜이 구동되는 차량본체와; 상기 차량본체의 전륜에 결합되어 상기 차량본체의 조향방향을 조절하는 조향부와; 상기 차량본체의 이동을 제동하는 제동부와; 상기 차량본체의 전면, 측면 및 후방의 장애물을 감지하는 장애물감지부와; 상기 장애물감지부의 감지결과에 따라 차량본체가 자동으로 평행주차가 되도록 상기 조향부와 상기 제동부 및 상기 DC모터를 제어하는 ECU를 포함하되, 상기 장애물감지부는 전방적외선센서, 후방적외선센서, 복수개의 측면적외선센서를 포함하며, 상기 차량본체가 이동할 때 상기 복수개의 측면적외선센서가 측면공간을 감지하여 상기 차량본체가 주차가능한 공간인지 판단하는 단계와; 상기 주차가능 공간 전방 장애물과 일정 거리가 될 때까지 전진하는 단계와; 설정된 후방거리까지 상기 주차가능 공간으로 우향후진하는 단계와; 설정된 후방거리까지 좌향후진하는 단계와; 설정된 전방거리까지 우향전진하는 단계와; 설정된 후방거리까지 후진하는 단계와; 차량본체의 측면정렬을 위해 차량본체를 일정 거리만큼 좌향후진 및 우향전진하는 단계와; 설정된 후방거리까지 후진하여 주차가능 공간 정중앙에 상기 차량본체가 위치되면 상기 차량본체를 제동하는 단계를 포함하는 것을 특징으로 한다.
