종래의 차량 블랙박스 영상은 차량의 블랙박스 장치의 메모리에 저장되어 있어서, 그 촬영 영상을 확인하기도 힘들고, 업로드하기도 힘들다.Since the conventional vehicle black box image is stored in the memory of the vehicle's black box device, it is difficult to check and upload the captured image.

만일 인터넷 서버에 그 촬영 영상을 업로드할 수 있도록 하려면, 차량에 통신장치를 구비하여야 하므로, 많은 비용이 든다.If the photographed image can be uploaded to an Internet server, a communication device must be provided in the vehicle, which incurs a high cost.

본 발명에서는 스마트폰이 근거리통신(예들 들면, 블루투스 통신, 와이파이 통신)을 이용하여 차량에서 촬영한 영상을 전달받은 후 스마트폰의 기능을 이용하여 인터넷망에 접속한 후 차량에서 촬영한 영사을 인터넷 서버 등에 저장할 수 있다. 따라서 비교적 저렴한 비용으로 차량에서 촬영한 영상을 인터넷 서버 등에 업로드할 수 있다.In the present invention, after the smartphone receives the image captured in the vehicle using short-range communication (for example, Bluetooth communication, Wi-Fi communication), it connects to the Internet network using the function of the smartphone, and then transmits the projection photographed in the vehicle to the Internet server. Can be stored on the back. Therefore, it is possible to upload an image shot by a vehicle to an Internet server at a relatively low cost.

따라서 차량에는 촬영 영상을 장기간 보관하는 대규모 기억장치를 설치할 필요가 없고, 나중에 차량의 운행 영상을 보고 싶을 때는 인터넷 서버로부터 촬영 영상을 전달받아 스마트폰을 이용하여 쉽게 확인할 수 있다.Therefore, there is no need to install a large-scale memory device for storing the captured image for a long period of time in the vehicle, and when you want to view the driving image of the vehicle later, the captured image can be received from the Internet server and can be easily checked using a smartphone.

상기 전방 카메라(110)와 후방 카메라(120)은 촬영방향이 수평방향보다 아래쪽으로 향하고 있어서, 차선까지 촬영이 가능하다. 따라서 상기 스마트폰은 상기 전방 카메라(110)와 후방 카메라(120)의 촬영 영상을 분석하여 차량 운행시 차선을 차선을 침범하는 것으로 판단되면 차선 침범 경고신호를 출력하도록 할 수도 있다. 즉 운전자가 졸음 운전 등을 이유로 차선에 지나치게 접근하거나 차선을 침범한다면 스마트폰의 스피커를 통해 경고음이 출력되도록 할 수 있다.Since the front camera 110 and the rear camera 120 have a photographing direction facing downwards than a horizontal direction, a photographing can be performed to a lane. Accordingly, the smartphone may analyze the image captured by the front camera 110 and the rear camera 120 to output a lane infringement warning signal when it is determined that the vehicle is invading the lane while driving the vehicle. In other words, if the driver approaches the lane excessively due to drowsy driving, etc., or invades the lane, a warning sound can be output through the speaker of the smartphone.

차선에 접근한 경우, 차선 접근 경고음을 출력하고, 차선을 벗아난 경우 차선 이탈 경고음을 출력하도록 할 수 있다.When approaching a lane, a lane approach warning sound may be output, and when a lane departure warning sound is output, a lane departure warning sound may be output.

그리고 차량이 차선에 접근할 때마다 경고신호가 출력된다면, 운전자가 차선을 변경할 때마다 경고신호가 출력될 것이다. 따라서 운전자가 방향지시등을 켠 후 그 방향으로 차선을 침범한다면, 경고신호가 출력되지 않는 것이 바람직하다. 본 발명에서는 제어부(150)가 방향지시등 작동 여부에 대한 정보를 수신하여 근거리통신부(160)을 통해 스마트폰(200)에 전송할 수 있도록 한다.And if a warning signal is output whenever a vehicle approaches a lane, a warning signal will be output whenever a driver changes lanes. Therefore, it is desirable that the warning signal is not output if the driver breaks into the lane in that direction after turning on the turn signal. In the present invention, the control unit 150 receives information on whether or not the direction indicators operate, and transmits the information to the smart phone 200 through the short-range communication unit 160.

따라서 스마트폰은 방향지시등 작동 여부를 미리 알 수 있으므로, 방향지시등에 표시된 방향으로 차선을 침범하는 경우 경고신호가 출력되지 않도록 할 수 있다.Therefore, since the smartphone can know in advance whether the turn signal is activated, the warning signal can be prevented from being output when the lane is invaded in the direction indicated on the turn signal.

제어부(150)가 방향지시등 작동 여부에 대한 정보를 수신하는 방법의 예는 방향지시등 작동장치의 조작부에 센서를 설치하고 그 센서의 출력을 제어부(150)에 전달하는 것이다. 이렇게 하면 방향지시등 작동장치의 조작부가 어떻게 조작되고 있는지를 알 수 있다.An example of a method for the control unit 150 to receive information on whether or not the turn signal lamp is operated is to install a sensor on the operation unit of the turn signal operation device and transmit the output of the sensor to the control unit 150. This way, you can see how the control panel of the turn indicator actuator is being operated.

전방 거리측정센서(130)와 후방 거리측정센서(140)는 차량에 접근하는 물체를 감지하고 그 물체까지의 거리를 구할 수 있으므로, 차량에 접근하는 위험물체가 있으면 스마트폰에 위험 경고신호가 출력되도록 할 수 있다. 위험 경고신호는 스마트폰의 스피커를 통해서도 출력할 수 있지만, 스마트폰의 디스플레이부를 통해서도 출력할 수 있다.Since the front distance measurement sensor 130 and the rear distance measurement sensor 140 can detect an object approaching the vehicle and obtain the distance to the object, a danger warning signal is output to the smartphone when there is a dangerous object approaching the vehicle. You can do it. The danger warning signal can also be output through the speaker of the smartphone, but can also be output through the display of the smartphone.

제어부(150)는 접근하는 물체의 존재 및 거리를 정확하고 신속하게 추정하기 위해, 전방 거리측정센서(130)와 후방 거리측정센서(140)의 측정 결과 뿐 아니라 전방 카메라(110)와 후방 카메라(120)의 촬영 영상까지 스마트폰(160)에 전송할 수 있다. 스마트폰(160)은 전방 거리측정센서(130)와 후방 거리측정센서(140)의 측정 결과 뿐 아니라 전방 카메라(110)와 후방 카메라(120)의 촬영 영상까지 활용하여 물체가 차량에 접근하고 있어서 위험하다고 판단되면 경고신호를 출력할 수 있다.In order to accurately and quickly estimate the existence and distance of an approaching object, the controller 150 not only measures the results of the front distance measurement sensor 130 and the rear distance measurement sensor 140, but also the front camera 110 and the rear camera ( Even the captured image of 120) can be transmitted to the smartphone 160. The smartphone 160 utilizes not only the measurement results of the front distance measurement sensor 130 and the rear distance measurement sensor 140, but also the photographed images of the front camera 110 and the rear camera 120, and the object approaches the vehicle. If it is judged to be dangerous, a warning signal can be output.

이때 위험물체의 접근이 있을 때, 접근 거리에 따라 위험성을 다르게 판단하여 경고신호의 크기와 강도를 다르게 조정할 수 있다.At this time, when there is an approach of a dangerous object, the size and intensity of the warning signal can be adjusted differently by judging the danger differently according to the approach distance.

운전 중 위험물체의 접근에 대해 경고신호를 출력할 수도 있지만, 정차 후 차량의 탑승자가 차문을 열 때 위험물체가 접근할 수도 있다.(현재 탑승자가 하차하기 위해 차문을 열 때, 오토바이나 자전거가 접근하여 부딪치는 사고가 자주 발생하고 있다.)A warning signal may be output for the approach of dangerous objects while driving, but dangerous objects may approach when the vehicle occupant opens the door after stopping. (When the current occupant opens the door to get off the vehicle, a motorcycle or a bicycle may enter the vehicle. Accidents that approach and collide are frequently occurring.)

따라서 상기 스마트폰은 차량 정차 후 차문을 열 때 물체가 접근하는 것으로 판단되면 경고신호를 출력할 수 있도록 하는 것이 바람직하다.Therefore, it is preferable that the smartphone outputs a warning signal when it is determined that an object is approaching when the vehicle door is opened after stopping the vehicle.

즉 스마트폰이 전방 거리측정센서(130)와 후방 거리측정센서(140)의 측정 결과, 전방 카메라(110)와 후방 카메라(120)의 촬영 영상을 분석하여 위험 물체가 접근하는 것으로 판단되면,That is, when the smartphone analyzes the measurement results of the front distance measurement sensor 130 and the rear distance measurement sensor 140, the images captured by the front camera 110 and the rear camera 120, and determines that a dangerous object is approaching,

차량의 제어부(150)에 차문 잠김 명령(차문 잠금장치가 잠기도록 하는 명령)을 전달하여 차량의 제어부(150)가 차량의 문을 잠그도록 한다. 따라서 탑승자는 차문을 열 수 없게 되고, 사고를 예방할 수 있게 된다.The vehicle door locking command (command to lock the vehicle door locking device) is transmitted to the vehicle controller 150 so that the vehicle controller 150 locks the vehicle door. Therefore, the occupant cannot open the car door, and an accident can be prevented.

이렇게 동작할 수 있기 위해서는 스마트폰과 통신하는 제어부(150)가 차문 잠금장치를 제어할 수 있어서, 열림상태를 잠금상태로 바꿀 수 있어야 한다.In order to be able to operate in this way, the control unit 150 communicating with the smartphone can control the car door locking device, so that the open state must be changed to the locked state.

또한, 스마트폰이 상기와 같이 동작하려면, 스마트폰이 상기와 같이 동작하도록 하는 앱(애플리케이션 프로그램)이 스마트폰에 설치되어 있어야 한다.In addition, in order for the smartphone to operate as described above, an app (application program) that allows the smartphone to operate as described above must be installed on the smartphone.
