The present invention relates to a driving monitoring system and a method of the surrounding vehicle, in particular, the user convenience for changing lanes and acceleration and deceleration by displaying the position and distance of the surrounding vehicle with respect to the left and right sides as well as the front and rear of the vehicle while driving. The present invention relates to a driving monitoring system of a surrounding vehicle capable of providing a function, and a method thereof.

In general, a vehicle is equipped with a room mirror and a left and right side mirror to allow the driver to have a view of the left and right and rear with the front, but such a mirror does not allow the driver to have a view in all directions. The left and right sides of the vehicle are formed with blind spots that are not secured by the side mirrors.

In order to secure the view of the blind spot, the driver may use an auxiliary mirror according to his or her taste, but this is also not a perfect solution, and there is a problem in that the user's view is dispersed to see each mirror.

Provides a clear line of sight for safe parking during reverse parking.

However, such a conventional sensing system is mainly used only to secure the field of view for forward and reverse when the vehicle is parked, and does not provide a special function while driving. In particular, there is a problem in that it does not provide a view of the left and right blind spots. .

In addition, while driving the vehicle, it is necessary to check the position or distance of the surrounding vehicles. Moreover, when the lane is to be changed, it is necessary to check whether there is a driving vehicle in the next lane and to change the lane, but it is not possible to accurately check the state of the surrounding vehicle. Changing lanes under conditions can be very dangerous.

In addition, there is a need for a detection system that can determine the position and distance to the surrounding vehicle while driving, since the vehicle may collide if the vehicle is not sufficiently secured in front and rear.

The present invention has been proposed to solve the above problems, the driver's front panel LCD monitor displays the position and distance of the front and rear and left and right surrounding vehicles in real time not only when the vehicle is parked, but also during driving. An object of the present invention is to provide a driving monitoring system and a method of driving a surrounding vehicle that can sufficiently secure the field of view.

The present invention for achieving the above object is a plurality of sensing means mounted on the vehicle to periodically detect the surrounding vehicle while driving; An image receiver which receives a sensed image of the sensing means; The data processor configured to calculate a location and distance of the surrounding vehicle based on the received image and generate a vehicle icon corresponding thereto; And a display unit configured to display a vehicle icon generated according to the calculation result around an icon corresponding to the vehicle.

In the present embodiment, the four cameras 212 to 218 are arranged to concentrate on the upper end of the vehicle 300 in a front, rear, left, and right structure so that a blind spot is not generated.

For example, as shown in FIG. 3, the vision camera 212 installed in the front (a) monitors the side / front vehicle from the 10 o'clock position to the 2 o'clock direction of the vehicle 300, and the right side (b). The vision camera 214 installed in the vehicle monitors the vehicle in the right / diagonal direction from the 1 o'clock direction to the 5 o'clock direction of the vehicle 300, and the vision camera 216 installed at the rear c is connected to the vehicle 300. The side / rear vehicle from 4 o'clock to 8 o'clock is monitored, and the vision camera 218 installed on the left side d monitors the left / diagonal vehicle from the 7 o'clock to 11 o'clock of the vehicle 300. .

On the other hand, when four or more cameras are used, each camera may be arranged around the outer periphery of the vehicle 300.

The data processor 230 determines the number of neighboring vehicles located in a predetermined transaction with the vehicle 300 based on the image received from the image receiver 220, and generates a number of vehicle icons corresponding to the calculated neighboring vehicles. Control the vehicle icon to be displayed on the display unit 240 according to the distance and position of the.

The display unit 240 is installed around the driver's seat instrument panel, for example, as an LCD monitor, and displays a vehicle icon generated by the data processor 230.

In the driving monitoring system of the surrounding vehicle according to the embodiment of the present invention configured as described above, when the vision cameras 212 to 218 detect the state of the front, rear, left, and right of the vehicle 300, the detected image is the image receiver 220. Is entered. The video signals input from the four vision cameras 212 to 218 are processed in a series of data to be displayed on one monitor 240 screen.

That is, the data processor 230 calculates the position and distance of the surrounding vehicles based on the input image signal, generates a vehicle icon corresponding thereto, and displays the position and driving state of the surrounding vehicle on the display unit 240 near the driver's seat. By displaying the icon, it is possible to provide safe driving for lane change and acceleration / deceleration while driving.

Hereinafter, a driving monitoring method of a surrounding vehicle according to an exemplary embodiment of the present invention will be described with reference to FIGS. 4 to 6.

4 is an exemplary view of a surrounding vehicle while driving to explain the driving monitoring system of the surrounding vehicle according to an embodiment of the present invention, FIG. 5 is an exemplary view of a driving monitoring display of the surrounding vehicle corresponding to FIG. 4, and FIG. A flowchart illustrating a driving monitoring method of a surrounding vehicle according to an exemplary embodiment of the present invention.

First, as shown in FIG. 4, the second vehicle 400a on the right side, the third vehicle 400b on the rear side, and the first vehicle, which is the vehicle 300 on which the driving monitoring system 20 is mounted, Vehicle 400c on the left side, vehicle 400d on the left side diagonally, vehicle 400d on the left side, and vehicle 400e on the front side of the vehicle 400, respectively, are driven in the respective directions 300a in the vehicle 300. It is assumed that four vision cameras are installed.

When the driving monitoring system 20 is started while driving in the above state, the plurality of sensing means 210 mounted on the vehicle 300 detects the surrounding vehicles 400a to 400e (step S601).

3 and 4, the four cameras 212 to 218 sense the state of the surrounding vehicles 400a to 400e in all directions a to d without the blind spot.

The distance and the position of the surrounding vehicles 400a to 400e are calculated based on the detection result of the sensing means 210 (step S602).

That is, the data processor 230 receives an image from the four cameras 212 to 218 through the image receiver 220, and calculates the position and distance of the surrounding vehicles 400a to 400e based on the vehicle 300. One display unit 240 processes to display on the screen.

Next, vehicle icons 242 and 244a to 244e corresponding to the position and distance calculation results of the surrounding vehicles 400a to 400e are generated and displayed on the display unit 240. More specifically, first, the data processor 230 Based on the result of the calculation, the number of surrounding vehicles within a predetermined distance from the vehicle 300 is determined (step S603).

Here, the number of vehicle icons corresponding to the determination result is generated (step S604).

For example, as shown in FIG. 5, when all of the surrounding vehicles 400a to 400e are located within a predetermined distance from the vehicle 300, the surrounding vehicle icons corresponding to the five surrounding vehicles 400a to 400e ( 244a to 244e are generated, and the vehicle icon 242 corresponding to the vehicle 300 is generated by default.

The surrounding vehicle icons 244a to 244e generated as described above are displayed on the display unit 240 according to the position and distance calculation result of the data processor 230 centering on the vehicle icon 242 of the vehicle 300 that is driving. The surrounding situation is displayed (step S605).

That is, a vehicle icon generated based on the images received by the four vision cameras 212 to 218 is displayed on the display unit 240, which is a driving monitor installed in the driver's seat instrument panel, so that the driver may move the vehicle around the vehicle 300. You can check the status of (400a ~ 400e) through the monitor.

Here, the surrounding vehicle icons 244a to 244e are displayed together with the distance from the vehicle 300. For example, as shown in FIG. 5, the first vehicle and the second vehicle (the vehicle 300) ( The distance between the vehicle 400a and the vehicle 400a is 0.7m, and the distance between the vehicle 300 and the vehicle 400d is 4.8m diagonally, and the distance between the vehicle 300 and the vehicle 400e is 400m. The distance from the bumper to the bumper is 3.7 m and is displayed on the surrounding vehicle icons 244a to 244e.

Next, the above steps (steps S601 to 605) are repeatedly performed and updated on a periodic basis.

That is, since the position and distance of each vehicle are changed by the vehicle speed or lane change, each vehicle is updated and displayed on the screen of the monitor 240 in real time.

Specifically, when the data processor 230 determines whether to update (step S606) and does not update because it does not have a constant period, the vehicle icon display state of step S605 is maintained, and a predetermined period elapses to update. In the case, the process returns to step S601 and steps S601 to S605 are repeatedly performed.

In this way, the driver can check the driving state of the surrounding vehicle displayed in real time on the driver's seat monitor screen to determine whether to perform lane change or acceleration / deceleration while driving, and drive safely.

As described above, the driving monitoring system and the method of the surrounding vehicle according to the present invention is equipped with a plurality of vision cameras on the upper part of the vehicle to monitor the four sides of each vision camera and the image data processing unit based on the detected image By configuring the driving conditions such as the position and the distance between the front, rear, left and right surrounding vehicles on one screen and displaying the surrounding situation on the LCD monitor with the vehicle icon, the driver can provide the position and distance between the surrounding vehicles in real time. Therefore, there is an effect that can provide safe driving during acceleration and deceleration or left and right lane changes through the monitoring screen not only during parking but also during vehicle driving.
