The present invention relates to a system for automatically generating road information and a region of interest using a vehicle navigation and a method of providing the same, and in particular, by detecting road breakage conditions and sudden curve sections on a road and storing them as part of map information along with current location information. After that, if the current position is part of the movement route, the user may be prepared in advance by bypassing the route or warning in advance.

Although the map information of the navigation system used up to now provides convenient information for driving, it is generally not to reflect the information on road surface conditions that occur frequently.

According to the navigation system, when a vehicle approaches a point of interest (hereinafter referred to as POI) on a map, a message selected from preset messages in the navigation system is expressed through a speaker.

In addition, if the vehicle speed is fast by determining whether the vehicle is close to the POI region based on the distance from the current position of the vehicle to the POI, a situation may occur with sufficient margin.

In this case, the driving direction is not considered when determining whether the vehicle is close to the POI. Thus, in the case of road information whose necessity of guidance depends on the traveling direction of the vehicle, unnecessary guidance messages are displayed on the vehicle in the opposite direction. Will also occur.

FIG. 1 is a schematic diagram of safety information detection in a conventional navigation system. The vehicle includes a position measuring unit 11 for acquiring a position signal of a current vehicle through GPS while driving a vehicle, and a road position or driving speed of the vehicle. It consists of a navigation application execution processing unit 10 which checks the coordinates of the map data storage unit 15 defined by time and location and displays the current position on the screen output unit 12 and the sound output unit 13.

Conventional navigation safety information detection device provided as described above provides a convenient driving information for the driver to drive the car, but does not reflect the information on the road surface conditions that occur from time to time there was a problem that the driver is somewhat difficult to grasp.

In addition, the map information displayed on the two-dimensional plane or three-dimensional simulation does not display the information on the steep slope, unpaved road or the like, and did not provide specific road information to the user in advance, resulting in a problem of safe driving.

In order to solve the above problems, the present invention, by embedding the six-axis acceleration sensor and the tilt sensor in the navigation to analyze the moving direction, acceleration, deceleration information of the vehicle body quantitative numerically to determine the effect of the correlation between the road surface and the vehicle on the safety The purpose of the present invention is to provide a system for automatically generating road information and a region of interest using a car navigation system that can improve vehicle protection and driver safety by analyzing and reflecting it on map information.

In order to achieve the above object, the present invention, the position measuring unit for determining the position of the vehicle through the GPS satellite, the driving time to the destination according to the road condition and driving speed to be compared with the position signal of the vehicle identified through the GPS satellite And a map data storage unit defined by coordinates for each location, a screen output unit for displaying map information on the current location of the vehicle by comparing the coordinates defined in the map data storage unit, and the map information and the position measuring unit.

Storage stable road information (POI) characterized by comprising: a.

In order to achieve the above object, the present invention provides a first process of detecting a safe driving route of a vehicle, a second process of generating a preliminary warning when driving in a dangerous section of the detected driving route, and dangerous information on the dangerous section. Characterized in that it comprises a third process of collecting and expressing.

The present invention combines the 6-axis acceleration sensor (shock sensor) and the inclination sensor with the navigation automatically detects the sharp curve, steep slope or road surface irregularities measured while driving the vehicle and stores it in the location information on the map, and later As part of the search (driving) route, this place alerts you to dangers in advance and protects your vehicle so that drivers can be prepared in advance.

Ultimately, it is possible to provide the user with information about road pavement (or unpaved) status and slope sections, so that they can prepare for digging in a specific area in advance. In addition, it is possible to secure the driver and the vehicle by preparing a sharp curve according to the movement of the inertia through the six-axis sensor for the section.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 2 is a navigation diagram of road information learning and POI automatic generation function using a sensor to which the present invention is applied, and takes into account the position signal of the vehicle and the road state and driving speed determined through the GPS satellites of the position measuring unit 120. The navigation application performing processor 110 transmits the current location information of the vehicle to the driver through the screen output unit 130 and the sound output unit 140 by comparing the coordinates of the map data storage unit 160 defined for each location. And a road information learning processor 180 and road information learning to acquire and utilize road conditions and road information through an acceleration and slope measuring unit 181 that detects road surface information on a road in real time separately from the navigation application. It consists of a road safety information (POI) storage unit 170 that can store meaningful information recognized through the processing unit 180.

Looking at the operation according to the road information learning and POI automatic generation function navigation configuration using the sensor made as described above are as follows.

First, when the vehicle starts to run, the navigation application performing processor 110 acquires the position signal of the current vehicle by the GPS of the position measuring unit 120 and compares the coordinates of the map data storage unit 160 with each other. The current position is identified and displayed on the screen output unit 130.

In the present invention, the road information learning processing unit 180 is present and operated separately from the navigation application performing processing unit 110, which detects the shocks of various states transmitted to the vehicle running on the road surface, and then generates these shocks. Quantify and analyze with meaningful signals. Meaningful signals that can be observed at this time are as follows.

▲ tilt level detection

▲ Rapid curve level detection according to the inertia that appears during vehicle movement

▲ Detects impact level due to road breaks and bumps

▲ Detecting sections of paved or unpaved roads, detecting the condition of pavement

▲ Detecting convex and concave and convex position information

In general, the 6-axis acceleration sensor is a sensor that can measure the direction of motion and the acceleration (including-acceleration) for each axis about the X, Y, Z three axes. The inclination sensor measures the inclination of the vehicle's three axes.

The 6-axis acceleration sensor is used to measure the change in acceleration transmitted to the vehicle by dividing the above-described X (left, right), Y (up, down), and Z (straight) axes into the respective axes.

Then, the acceleration value for each axis is sampled 10 times per second (0.1 second unit) to calculate the equivalent acceleration value in 1 second unit. Again, the change in the equivalent acceleration values of these values is measured to measure the change in the vehicle's movement speed and acceleration.

The navigation incorporating the acceleration sensor and the tilt sensor continuously detects the inclination values of all the accelerations applied to the vehicle while driving, and these data are converted into values quantified by the road information learning processor 180, and this value. These changes are processed into meaningful data such as sharp curves, steep slopes and broken roads that the driver can understand.

The data and the position value of the current user identified from the position measuring unit 120 are stored in the safety information (POI) storage unit 160 through the navigation application execution processing unit (main processing unit) 110.

At this time, the user refers to the data of the safety information storage unit 170 during the operation via the path stored in the safety information storage unit 170 as follows, before the user passes this point, the navigation application performing processing unit 110. To help the driver call attention and be prepared.

In addition, the user can collect the meaningful data through the vehicle movement and update the latest data verified through the server sharing and updating this data.

Now look at the details of the road information and the region of interest automatic generation using the navigation as follows.
