Description

차량의 주차가능공간 판단장치Vehicle parking space judging device

본 발명은 차량의 주차가능공간 판단장치에 관한 것으로서, 상세하게는 차량의 각 모서리에 장해물을 감지하는 감지센서를 설치하고 이러한 감지센서에 감지된 감지값에 따라 차량의 주차시 부여된 공간에 자기차량이 주차할 수 있는지의 가능여부를 판단할 수 있도록 한 차량의 주차가능공간 판단장치에 관한 것이다.The present invention relates to an apparatus for determining a parking space of a vehicle. Specifically, a sensor for detecting an obstacle is installed at each corner of the vehicle, and the magnetic sensor is installed in a space given when the vehicle is parked according to the detected value detected by the sensor. The present invention relates to a parking space judging device for a vehicle to determine whether the vehicle can park.

일반적으로 차량의 주차에 있어서 운전자는 자기차량의 크기와 확보된 주차공간을 비교하여 차량의 주차여부를 판단하게 된다.In general, when the vehicle is parked, the driver compares the size of the vehicle with the reserved parking space to determine whether the vehicle is parked.

이러한 주차공간은 주변의 차량이 서로 방해받지 않도록 함이 필수적인 요소인 바, 주차장 뿐 아니라 좁은 골목 등 한정된 공간에서는 최대한 공간을 활용하여 주차해야만 많은 차량이 주차할 수 있게 된다.Such parking spaces can be parked by using as much space as possible in limited spaces such as bars and car parks, as well as narrow alleys, where it is essential that the surrounding vehicles are not disturbed.

그러나 초보운전자 등과 같이 운전상황에 미숙한 운전자의 경우에는 부여된 주차공간에 자기차량이 주차할 수 있는 지의 가능여부를 판단하는 데 어려움이 있는 것이며, 숙달된 운전자의 경우에도 좁은 공간에 주차시에는 주어진 공간과 자기차량과의 크기를 한 눈에 파악하여 정확하게 주차가능여부를 파악하기에 난해하며 자칫 차량의 손상을 줄 우려가 있어서 주차에 상당한 곤란함이 있게 되는 문제점이 있다.However, in the case of drivers who are inexperienced in driving conditions such as novice drivers, it is difficult to determine whether or not their vehicle can park in the assigned parking spaces. There is a problem that it is difficult to grasp the size of the given space and the own vehicle at a glance and accurately determine whether parking is possible, and there is a considerable difficulty in parking because there is a risk of damaging the vehicle.

본 발명은 상기한 종래의 문제점을 감안하여 안출한 것으로서, 본 발명의 목적은 부여된 주차공간에 대하여 자기차량의 주차가능여부를 판단할 수 있는 차량의 주차가능공간 판단장치를 제공하는 데 있다.SUMMARY OF THE INVENTION The present invention has been made in view of the above-described conventional problems, and an object of the present invention is to provide a parking space determination apparatus of a vehicle capable of determining whether or not parking of a vehicle is possible with respect to a given parking space.

이하 첨부된 예시도면을 참조하여 본 발명의 바람직한 실시예를 보다 상세히 설명하면 다음과 같다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

먼저 도 1은 본 발명의 따른 감지센서의 설치위치 예시도로서, 도시한 바와 같이 차량의 각 모서리 부위에 장해물을 감지하도록 하는 감지센서(S)를 설치한다. 그리고 이러한 감지센서(S)는 도 2에 본 발명의 구성을 나타낸 블록도에 도시한 바와 같이 제어부(C)에 연결되어 감지값이 입력되도록 하고, 상기 제어부(C)로부터는 경보수단(B)이 연결 구성된다. 이러한 경보수단으로는 부저를 예시할 수 있다.First, Figure 1 is an exemplary installation position of the detection sensor according to the present invention, as shown in the installation of the detection sensor (S) to detect the obstacle in each corner of the vehicle. And such a detection sensor (S) is connected to the control unit (C) as shown in the block diagram showing the configuration of the present invention in Figure 2, so that the detection value is input, from the control unit (C) the alarm means (B) This connection is made up. As the alarm means, a buzzer can be exemplified.

이상과 같이 구성되는 본 발명을 도 2, 도 3 및 플로우차트를 참고로 설명하면 다음과 같다.The present invention configured as described above will be described with reference to FIGS. 2, 3 and a flowchart as follows.

도 3은 본 발명의 설명을 위하여 주차공간에 차량이 접근한 상태를 나타낸 예시도로서, 도면에서 설명부호 'FL'은 전방의 좌측인 전좌, 'FR'은 전우, 'RL'은 후좌, 'RR'은 후우 방향을 나타낸 것이다. 또한 'A'는 주차공간의 측정폭이고, a, b, c 는 각각의 위치에 따른 거리이다.3 is an exemplary view illustrating a state in which a vehicle approaches a parking space for the purpose of describing the present invention. In the drawings, reference numeral 'FL' is a front left, 'FR' is a front left, 'RL' is a rear left, ' RR 'represents the direction of the rightward direction. In addition, 'A' is the measured width of the parking space, a, b, c is the distance according to each position.

먼저 도 3에 도시한 바와 같이 차량이 주차공간에 접근하면 주차가능여부를 타진하기 위하여 작동스위치(SW1)를 작동시킨다.First, as shown in FIG. 3, when the vehicle approaches the parking space, the operation switch SW1 is operated to detect whether parking is possible.

그리고 상기 작동스위치(SW1)의 작동에 따라 차량 각 모서리부에 설치된 감지센서(S)에 전원 인가되어 주변 장해물을 감지하도록 하게 된다.In addition, power is applied to the detection sensor S installed at each corner of the vehicle according to the operation of the operation switch SW1 to detect peripheral obstacles.

이때 도 3의 상황에서는 해당되는 상기 감지센서(S)의 FL(전좌)과 FR(전우)의 장해물 거리를 측정하여 가까운 측의 주차공간으로 계산하게 되며, 가까운측이 FL일 때 FL의 감지센서(S)로 소정시간(예컨대 50msec)마다 거리를 측정하게 된다. 이때 가까운 측이 FR이라면 이에 해당되는 감지센서가 거리를 측정하게 되고 작동플로우는 동일하게 된다.In this case, in the situation of FIG. 3, the distance of the obstacles of the corresponding sensor (S) and the FR (front right) of the corresponding sensor is measured and calculated as the parking space of the near side, and the detection sensor of the FL when the near side is FL. In S, the distance is measured every predetermined time (for example, 50 msec). At this time, if the near side is FR, the corresponding sensor measures the distance and the operation flow is the same.

그리고 상기 감지센서(S)로부터 신호를 입력받은 제어부(C)에서는 초기화 t = 0, b = 0에서 t=(t+50msec), b=FL과 장해물 측정거리가 되며, 측정거리 b＞a+100㎝이면 주차공간의 측정폭 A = 차속(10km 미만)×t 에서 측정폭(A)과 차량 전폭(W)을 비교하여 측정폭(A)이 차량전폭(W)보가 클 때 경보수단(B)에서 주차가능신호음을 발생시키고 그렇지 않을 때는 주차불가능신호음을 발생시키게 된다.In the control unit C, which receives the signal from the detection sensor S, t = (t + 50msec), b = FL and the obstacle measuring distance are initialized at t = 0 and b = 0, and the measurement distance b> a +. If the width of the parking space is 100cm, the measurement width A = the speed of the vehicle (less than 10km) x t is compared with the measurement width (A) and the vehicle width (W). ) Will generate a parking enable beep, otherwise it will generate a parking disable beep.

한편 차량이 주차공간에 접근시 작동스위치(SW1)를 작동시킨 후 주차에 따라 일렬주차모드스위치(SW2)를 작동시켰을 때는 도 3에서 측정폭(A)가 차량의 전장에서 여유분인 소정거리 100㎝를 더한 차량전폭(L)이 일치된 상태로서 작동은 이상 설명할 작동플로우와 동일하게 된다.On the other hand, when the vehicle operates the operation switch SW1 when approaching the parking space and then operates the row parking mode switch SW2 according to the parking, the measurement width A is a predetermined distance 100 cm in FIG. The operation of the vehicle width L plus the sum is the same, the operation is the same as the operation flow to be described above.

이상과 같이 본 발명은 차량의 주차시 해당되는 주차가능공간에 차량을 주차시킬 수 있는지의 여부를 판정하여 경보하게 되므로 초보자도 주차에 큰 어려움이 없게 되며, 파악하기 곤란한 주차공간에서 용이하게 판단을 내릴 수 있게 되어 편의성이 향상되고 장해물로 인한 차량의 손상을 방지하게 되므로 차량의 상품성 향상의 효과가 있다.As described above, the present invention determines whether or not the vehicle can be parked in the applicable parking space when the vehicle is parked and alarms, so that even a beginner does not have a great difficulty in parking, and the judgment is easily made in a difficult parking space. As it can be lowered, the convenience is improved and the damage of the vehicle due to the obstacle is prevented, thereby improving the merchandise of the vehicle.
