FIG. 2 is a flowchart illustrating a method of detecting and reporting a blind zone according to a traveling path characteristic of a vehicle according to the present invention. In the method of notifying a blind zone during running of a vehicle, A second step S200 of detecting a dead zone of the vehicle from a starting point of the danger zone on the driving route to a point of ending the danger zone on the driving route, A third step (S300) of setting an alert guide type, and a fourth step (S400) of displaying an alert according to the alert guide type and operating a device for generating an alert.

The first step S100 includes collecting information on a traveling route of the real-time vehicle through the navigation system 10, and displaying the characteristic of the area in which the danger is expected to occur on the traveling route.

Therefore, the section characteristic on the travel route is an area where an accident due to a blind spot is expected to occur while the vehicle is running, or an area requiring attention in changing the driving lane. The area is classified into a section, a road section, , The parking lot section, and the accident occurrence section.

In the present invention, the sections such as the congestion road section, the back road section, the intersection section, and the accident occurrence section are regarded as areas where a dangerous situation may occur at the time of lane change or driving rotation. There is a feature of the present invention that the safety of the running of the vehicle can be secured by performing the guidance.

For example, the above-mentioned back road generally has a narrow road width, does not pass for the purpose of passing through the vehicle, and is mostly used as a parking space without distinction between a sidewalk and a road. And the driver 10 is exposed to the risk of an accident. At this time, the navigation device 10 can grasp the vehicle route and guide the driver to the blind spot and the surrounding situation.

As another example, in the situation where the vehicle 10 rotates in the same way as the above-mentioned intersection section or the occurrence of a blind spot in a section in which there is a curvature according to the linearity of the road, the navigation device 10 grasps the vehicle path, Can be performed.

In a section in which a curvature due to the linearity of the road occurs, When detecting a dead zone in the direction, the detection range is reduced to detect a dead zone, and the detection zone of a dead zone in the outer direction can detect a relatively wide range of radius.

Therefore, in the section where the curvature due to the linearity of the road occurs, the screen area to be displayed when a device for displaying a blind spot and generating a notification is displayed is defined as a blind spot area in the center point direction, The sensing area can be displayed by distributing the display screen at a large ratio. In addition, the distribution of the screen area can be adjusted in proportion to the magnification of the road curvature. This is because, depending on the curvature, the space in the direction of the center point of the vehicle is reduced by that much.

The present invention is also characterized in that, in a parking lot section, the driver is informed about a blind spot at the time of traveling such as a lane change or a backward movement of the vehicle.

The second step S200 is a step in which the vehicle detects and detects a dead zone in the above-mentioned section on the traveling route. At this time, the device for detecting and detecting a dead zone of the vehicle may utilize the image input device 20 or the proximity sensor 30.

The approach detecting sensor 30 and the video input device 20 automatically detect a dead zone in an interval in which a danger is expected to occur on the running route detected in the first step S100.

The third step S300 is a step of setting an alarm guiding type according to a warning type generated as a result of detection of the blind spot. The warning guiding type is a rear warning type, a left / right side warning type, a parking warning type, Directional warning type, as shown in FIG.

In the third step S300, the warning type is set according to the driving state of the vehicle in the section where the danger is expected to occur. That is, if the section is a congestion road or a rear road section, Warning type, and if the section is a parking section, it is set as a rear warning type or a parking warning type.

In addition, in the rotation section corresponding to the intersection rotation section or the curvature of the road, the left / right side warning type is set for the surrounding situation according to the rotation of the vehicle, and the peripheral blind spot is detected more precisely.

The fourth step S400 is a step of operating a device for displaying a warning according to the warning guiding type and generating a notification, and the device may be a vehicle internal device such as AVN (audio, video, navigation) And a user wearable device 60 such as a smart watch or an HMD (Head Mount Display).

3A is a diagram illustrating an example of displaying an alert and generating an alert in an AVN device in a vehicle according to the present invention. FIG. 3B is an example of displaying an alert and generating an alert in the HMD device, and FIG. FIG. 8 is an exemplary view showing a warning displayed on a user smart watch device and generating a notification. FIG.
