차량의 측면에 다수 배열시키되, 상기 제 1 및 제 2 구동부(30)(40)의 구동으로 부터 차량의 측방과 후방으로 유동되어 그 측방 및 후방에 위치하는 장애물을 감지하는 장애물감지부(50); 로 구성함을 특징으로 한다.Obstacle detection unit 50 arranged in the side of the vehicle, the first and second driving unit 30, 40 flows to the side and rear of the vehicle from the drive of the obstacle detection unit 50 for detecting obstacles located on the side and rear ; It is characterized by the configuration.

이와같이 구성된 본 발명의 일실시예에 대한 작용을 첨부된 도 1 및 도 2를 참조하여 설명하면 다음과 같다.Referring to Figures 1 and 2 attached to the operation of an embodiment of the present invention configured as described above are as follows.

먼저, 차량의 주행이 이루어질 경우, 상기 차량의 제어시스템에 구비된 차속센서(1)는 주행중인 차량의 차속신호를 발생시킨 후 이를 제어부(10)로 출력한다.First, when the vehicle is driven, the vehicle speed sensor 1 included in the control system of the vehicle generates a vehicle speed signal of the vehicle being driven and then outputs it to the controller 10.

그러면, 상기 제어부(10)는 입력되는 차속신호에 따라 현재 차량이 주행중임을 판단한 후 그 판단신호를 센서방향설정부(20)로 출력하게 되고, 이에따라 상기 센서방향설정부(20)는 측방감지모드로 전환동작이 이루어진다.Then, the controller 10 determines that the vehicle is currently driving according to the input vehicle speed signal, and outputs the determination signal to the sensor direction setting unit 20. Accordingly, the sensor direction setting unit 20 is in the side sensing mode. Switching operation is performed.

더불어, 상기 센서방향설정부(20)는 측방감지모드로의 전환동작과 동시에 제 1 구동부(30)를 구동시키는 바,In addition, the sensor direction setting unit 20 drives the first driving unit 30 at the same time as the switching operation to the side sensing mode,

상기 제 1 구동부(30)의 구동으로 부터 차량의 측면에 다수 배열된 장애물감지부(50)는 도 2에 도시된 바와같이 차량의 측방을 향하면서 그 측방에 위치하는 장애물을 감지하게 되는 것이다.As shown in FIG. 2, the obstacle detecting unit 50 arranged on the side of the vehicle from the driving of the first driving unit 30 senses obstacles located on the side of the vehicle while facing the side of the vehicle.

이때, 운전자가 차량의 방향지시등을 동작시키면서 코너링이나 곡선주행을 진행할 때 상기 장애물감지부(50)로 부터 측방의 장애물이 감지되면, 상기제어부(10)는 표시 및 경보부(4)를 구동 제어한다.At this time, when the driver detects an obstacle on the side from the obstacle detecting unit 50 while cornering or driving a curve while operating the direction indicator of the vehicle, the control unit 10 controls the display and the alarm unit 4 to drive. .

그러면, 상기 표시 및 경보부(4)는 경보음 출력을 통해 운전자에게 장애물이 출현되었음을 환기시키고, 더불어 장애물의 위치를 디스플레이시켜 코너링이나 곡선주행에 따른 사각지대의 측방 장애물과 충돌을 예방할 수 있게 되는 것이다.Then, the display and alarm unit 4 is to alert the driver that the obstacle appeared through the alarm sound output, and also to display the position of the obstacle to prevent collision with the side obstacles in the blind spot due to cornering or curve driving. .

한편, 차량이 정차하는 경우, 상기 차량의 제어시스템에 구비된 차속센서(1)는 차속신호를 발생시키지 않게 되고, 이에따라 상기 제어부(10)는 차량이 현재 정차중임을 판단한 후 그 판단신호를 센서방향설정부(20)로 출력하므로서, 상기 센서방향설정부(20)는 후방감지모드로 전환동작이 이루어진다.On the other hand, when the vehicle stops, the vehicle speed sensor 1 provided in the control system of the vehicle does not generate a vehicle speed signal. Accordingly, the controller 10 determines that the vehicle is currently stopped and detects the determination signal. By outputting to the direction setting unit 20, the sensor direction setting unit 20 is switched to the rear sensing mode.

더불어, 상기 센서방향설정부(20)는 후방감지모드로의 전환동작과 동시에 제 2 구동부(40)를 구동시키는 바,In addition, the sensor direction setting unit 20 drives the second drive unit 40 at the same time as the switching operation to the rear sensing mode,

이때, 운전자나 탑승자가 정차중인 차량으로 부터 이탈하기 위해 도어를 열고자 할때 그 상태는 도어센서(3)에 의해 감지된 후 제어부(10)로 출력된다.At this time, when the driver or the occupant tries to open the door for departure from the stopped vehicle, the state is detected by the door sensor 3 and then output to the controller 10.

이때, 상기 장애물감지부(50)로 부터 후방의 장애물이 감지되면, 상기 제어부(10)는 도어록액추에이터(5)를 구동 제어하여 도어의 열림이 이루어지지 않도록 하는 한편, 표시 및 경보부(4)를 구동 제어하게 된다.In this case, when an obstacle behind the rear is detected from the obstacle detecting unit 50, the control unit 10 controls the driving of the door lock actuator 5 to prevent the door from being opened, and controls the display and alarm unit 4. Drive control.

그러면, 상기 도어록 액추에이터(5)에 의해 운전자는 물론 탑승자의 이탈이 방지된 상태에서, 상기 표시 및 경보부(4)는 경보음 출력을 통해 운전자나 탑승자에게 후방에 장애물이 출현되었음을 환기시키고, 더불어 장애물의 위치를 디스플레이시켜 운전자는 물론 탑승자의 이탈에 따른 사각지대의 후방 장애물과 충돌을 예방할 수 있게 되는 것이다.Then, in the state where the departure of the driver as well as the driver is prevented by the door lock actuator 5, the display and the alarm unit 4, through the alarm sound output to remind the driver or the passenger that the obstacle appeared in the rear, By displaying the position of the driver as well as to prevent the collision with the rear obstacles in the blind spot due to the departure of the occupants.

이상에서 설명한 바와같이 본 발명 유동형 센서를 이용한 차량의 사각지대 감지장치는 차량의 측면에 다수개의 센서를 배열하되 그 센서가 차량의 주행과 정차상태에 따라 측방 및 후방의 장애물 유무를 감지하도록 구성하므로서, 차량이 주행중일때에는 측방의 장애물 감지를 통해 안전운전이 가능하도록 함은 물론, 차량이 정차중일때에는 후방의 장애물 감지를 통해 운전자나 탑승자의 도어 열림으로 부터 발생할 수 있는 충돌(특히 오토바이)의 위험을 해소하는 특징을 갖는다.As described above, the blind spot detection apparatus for a vehicle using the flow sensor according to the present invention arranges a plurality of sensors on the side of the vehicle, and configures the sensors to detect the presence of obstacles on the side and the rear, depending on the driving and stopping conditions of the vehicle. In addition, when the vehicle is driving, it enables safe driving by detecting obstacles on the side, and also detects obstacles at the rear when the vehicle is stopped, so that the risk of collision (especially motorcycle) that can occur from the driver's or occupant's door opening. It has the feature to solve.
