2 is a flowchart illustrating a method for detecting and notifying a blind spot according to a driving path characteristic of a vehicle according to the present invention. In the method for notifying a blind spot while driving of a vehicle as shown in the figure, a driving route guidance and driving by the navigation device 10 The first step (S100) of identifying the section characteristics on the route, the second step (S200) of detecting and detecting the blind spot of the vehicle from the starting point to the end point of the dangerous section on the driving route (S200), according to the dangerous section on the driving route A third step (S300) of setting a warning guidance type, and a fourth step (S400) of operating a device that displays a warning and generates a notification according to the warning guidance type are included.

The first step ( S100 ) consists of collecting information on the driving route of the vehicle in real time through the navigation device 10 , and identifying and displaying characteristics of a section where danger is expected to occur on the driving route.

Therefore, the section characteristic on the driving route is an area in which an accident due to a blind spot is expected during driving of a vehicle or requires attention when changing a driving lane, and a section of a congested road, a section of a back road, and a section of an intersection on the driving route of the vehicle , means that it is section characteristic information of the road corresponding to any one of the parking lot section and the accident-prone section.

In the present invention, sections such as the congested road section, the back road section, the intersection section, and the accident-prone section are considered as areas in which a dangerous situation can occur when changing lanes or driving turns, and at this time, the driver is advised of the blind spot and surrounding conditions. There is a feature of the present invention that can promote the safety of vehicle driving by performing the guidance.

For example, the back road is generally narrow in width, does not pass for the purpose of passing vehicles, and is mostly used as a parking space without a distinction between sidewalks and roadways. Sections such as residential areas, neighborhood roads, and roads in front of school gates As a result, it can be viewed as an area where the driving volume is always exposed to the risk of an accident, and at this time, the navigation device 10 can identify the vehicle route and guide the driver to the blind spot and surrounding conditions.

As another example, in a situation in which a vehicle is rotated in the same place as the intersection section or a blind spot occurs in a section with a curvature according to the linearity of the road, the navigation device 10 identifies the vehicle route and provides guidance on the blind spot. can be done

At this time, FIG. 4 is an exemplary view showing the detection of a blind spot in a section in which the curvature due to the linearity of the road occurs according to the present invention, and as shown in the figure, the center point of the curvature in the section in which the curvature by the linearity of the road occurs. When detecting the blind spot in the direction, the detection range is reduced to detect the blind spot, and the detection area of the blind spot in the outer direction can detect a relatively wide radius.

Therefore, in the section where the curvature due to the linearity of the road occurs, the screen area displayed when the device that displays the blind spot and generates a notification is operated, the blind spot area in the direction of the center point is a small ratio, The detection area can be displayed by distributing the display screen in a large ratio. In addition, the distribution of the screen area may be adjusted in proportion to the magnification of the road curvature. This is because, depending on the curvature, the blind spot is reduced in the space in the direction of the center point when the vehicle is driven.

In addition, in the parking lot section, the present invention also provides guidance on the blind spot to the driver when the vehicle is driving, such as changing a lane or reversing, as a feature of the present invention.

The second step ( S200 ) is a step in which the vehicle detects and detects a blind spot in the above-described section on the driving route. In this case, the apparatus for detecting and detecting the blind spot of the vehicle may utilize the image input device 20 or the approach detection sensor 30 .

The approach detection sensor 30 and the image input device 20 automatically detect and detect a blind spot in a section where danger is expected to occur on the driving route identified in the first step (S100).

The third step (S300) is a step of setting a warning guidance type according to a warning type generated as a result of the detection of the blind spot, and the warning guidance type is a rear warning type, a left/right side warning type, a parking warning type, and a driving This is a step of setting any one of the direction warning types.

This means that, in the third step (S300), setting the warning guidance type according to the vehicle driving state in the section where the risk is expected to occur means that if the section is a congested road section or a back road section, a left/right lateral warning type or driving direction It is set to any one of the warning types, and if the section is a parking section, it means that it is set as a rear warning type or a parking warning type.

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

The fourth step (S400) is a step of operating a device that displays a warning and generates a notification according to the warning guidance type, wherein the device is an in-vehicle device such as AVN (Audio, Video, navigation) or a speaker. (50) and a smart watch (Smart Watch), it is characterized as a user wearable device (60), such as a HMD (Head Mount Display).

Therefore, FIG. 3A is an exemplary diagram illustrating that a warning is displayed and a notification is generated by an AVN device in a vehicle according to the present invention, FIG. 3B is an exemplary diagram illustrating that a warning is displayed and a notification is generated by an HMD device, and FIG. 3C is It is an example diagram showing that a warning is displayed and a notification is generated in the user's smart watch device.

An image of a dangerous area that may occur in response to a possible blind spot risk such as in the city can be displayed on AVN, and a warning sound is displayed from the speaker in the corresponding direction when warning the left/right side and rear depending on the location of the speaker inside the vehicle. It is possible to communicate with the user wearable device 60 wirelessly and display an image of a dangerous area on a display such as vibration generation or AVN display along with a corresponding warning icon.
