In addition, the vehicle 40 directly connects with the surrounding vehicles 20, 30, and 10 to receive location and speed information of the connected vehicles.

Therefore, the vehicle 10 may receive the position and speed information of the vehicle 20 that the vehicle 10 cannot directly access through communication with the vehicle 40.

3 is a block diagram showing the configuration of a terminal according to the present embodiment.

The terminal 100 is provided with a display capable of displaying graphic information, for example, in association with a GPS module that receives a navigation message mounted in a vehicle or received from a Global Positioning System (GPS) satellite in the vehicle. It includes various portable terminals (Portable Terminal). The vehicle 10 on which the terminal 100 is mounted is referred to as a 'vehicle' below.

Referring to FIG. 2, the terminal 100 includes a GPS receiver 110, a memory 120, a processor 130, a controller 140, a transceiver 150, a display 160, and an audio output 170. It may include.

It may be implemented.

 In addition, the controller 140 converts the movement or flow information of the surrounding vehicle, which is input through the processor 130, into image information using text and graphic information stored in the memory 120 and is displayed on the display unit 160. In addition, the controller 140 searches for a corresponding sound source file stored in the memory 120 to generate and output an audio signal from the sound output unit 170 if necessary.

The controller 140 controls the transceiver 150 to communicate with the surrounding vehicles 20 to 60 to transmit and receive driving information of the host vehicle 10 and the driving information of the surrounding vehicles 20 to 60. For example, the transmission and reception may be performed in a short period as long as possible, for example, in a period of 100 ms or less.

The display unit 160 may be implemented as a display device such as a liquid crystal display (LDC), for example, to display a video signal input from the controller 140.

In addition, the display unit 160 is implemented as a touch screen to display not only a display function but also various functions provided by the terminal 100 in a menu structure, and to a touch using a user's finger or a stylus pen. It may be implemented to simultaneously perform an input function for executing the menu selected by.

It may collect driving information such as the position and speed of the car.

4 is a diagram illustrating an example of displaying surrounding vehicle motion information on the display unit 160.

Referring to the drawing, the controller 140 retrieves data on a road shape such as a straight line, a curved road, an access road, and an intersection from the map data, processes the road shape graphically, displays it on the display unit 160, and then displays the own vehicle ( Based on 10), the surrounding vehicles 20 to 60 are represented by graphic elements such as figures and displayed at positions corresponding to the road shapes, respectively. Subsequently, the controller 140 changes the relative distance and the position of the host vehicle 10 according to the change of the position of each vehicle 10 to 60 with reference to the motion information of each vehicle 10 to 60 so as to display the road of the display unit 160. By displaying at the changed position on the form, the movement of the surrounding vehicles 20 to 60 on the screen can be displayed in the same manner as the relative movement between the actual host vehicle 10 and the surrounding vehicles 20 to 60.

In addition, the host vehicle 10 is displayed to be distinguished using different graphic elements or colors so as to be distinguished from other surrounding vehicles 20 to 60, and the speeds of the corresponding vehicles 10 to 60 are displayed inside each graphic element. . Here, although the graphic element is illustrated as a 2D figure, the present invention is not limited thereto, and may be represented by modeling as various graphic elements such as 2D or 3D photorealism.

On the other hand, a text indicating a relative distance is displayed on the right side of the screen based on the position of the host vehicle 10. Even if the position of the host vehicle 10 is changed, the text is fixedly displayed at a specific position on the screen and the positions of the surrounding vehicles 20 to 60 are displayed. May be changed or a vehicle (not shown) that is newly incorporated into the surrounding vehicle may be generated and displayed.

Here, as a result of analyzing the driving information of the vehicle 20 received through the vehicle 40 in the host vehicle 10, the speed of the vehicle 20 is drastically reduced to 0 km / h. Accordingly, the processor 130 executes the risk prediction program based on the location of the same lane as the 100 km / h of the speed of the host vehicle 20 as the speed of the vehicle 20 decreases rapidly. For example, when six seconds have elapsed from the current time, the distance between the vehicle 20 and the subsequent vehicle 40 is closer than a reference value, thereby predicting a collision.

Accordingly, the processor 130 inputs the dangerous information including the dangerous situation and the vehicle 20 which causes the dangerous situation to the controller 140, and the controller 140 displays the dangerous information on the display unit 160 and the sound output unit. The output through 170 may notify the driver.

Referring to the drawings, the vehicle 20, which is a risk factor, may be changed in color, size, or the like, or a warning of collision may be warned in an accent manner, for example, red, or flashing, and at the same time, the sound output unit 170 For example, a warning voice or alarm may be outputted, "Danger!

On the other hand, the memory 120 may be used as a basis for analyzing the cause of the accident in the event of an accident by buffering and updating the screen on which the movement information of the vehicles is displayed, for example, by about 5 minutes.

5 is another example of a method of displaying vehicle motion information on the display unit 160.

4, the controller 140 displays the speed of each vehicle 10 to 60 inside the graphic element and the distance to the host vehicle 10 from the outside. In addition, the controller 140 analyzes road information, motion information such as the location and route of each vehicle, sets the presence and direction of lanes, and displays the information on the screen of the display unit 160 to further improve the driver's identification.

On the other hand, the controller 140 changes the number of display vehicles according to the speed of the host vehicle 10 to display adjacent vehicles first, or changes the radius displayed on the screen according to the speed of the host vehicle 10 to change the surrounding area within a corresponding radius. Only vehicles can be displayed. For example, when the speed of the own vehicle 10 increases by 10 km / h, the number of displayed vehicles is increased by five, or the distance from the own vehicle 10 is displayed up to 150 m, and the vehicle which is in the range up to 150 m is displayed. Change is possible.

That is, in the case of the radius displayed on the screen, all the vehicles included in the radius set based on the host vehicle 10 may be displayed on the screen by adjusting the radius setting criteria based on the change in the braking distance according to the speed.

In addition, when the number of display vehicles is set to vary, the number of vehicles existing around the host vehicle 10 may be displayed as many as a preset or user-set number, and the number of displayed vehicles is displayed by a user on an input unit (not shown). It can be implemented so that it can be changed easily.

In addition, even when the surrounding vehicles are displayed based on the radius from the host vehicle 10, the radius may be easily changed by the user through an input unit (not shown).

Accordingly, the controller 140, in association with the processor 130, drives the neighboring vehicles stored in the memory 120 based on the speed of the host vehicle 10, a user selection or a predetermined radius, and a user selection or preset vehicle number information. Information is retrieved, and if necessary, the transceiver 150 is controlled to collect driving information of surrounding vehicles to be displayed on the screen through a mesh network.

In addition, the controller 140 predicts a surrounding vehicle path through a risk prediction program of the processor 130 and, for example, when a direction change is made based on driving information of the host vehicle 10, for a vehicle located in the corresponding direction. The driving information is collected through the mesh network, and the processor 130 analyzes the collected driving information to calculate the motion information, and the controller 140 displays the motion information of the vehicle on the screen based on this.

Collecting and updating driving information of the surrounding vehicle of the controller 140 is preferably performed in a short period of time possible, for example, 100 ms.

The processor 130 analyzes the surrounding vehicle movement pattern based on the periodically updated driving information of the surrounding vehicle and detects the overtaking vehicle, the braking vehicle, the interrupting vehicle, the drowsy driving vehicle, the signal violation vehicle, and the like to detect the risk of the surrounding vehicle. Predict and classify dangerous vehicles.

Thus, for example, vehicles with a risk level above the reference level are classified as dangerous vehicles, for example, represented by a red graphic element, and safety vehicles determined to be without risk are indicated by a green graphic element. Vehicles not classified as cautions may be marked with orange graphic elements as caution vehicles.

6 is another example of a method of displaying vehicle motion information on the display unit 150.

Referring to the drawings, the description is similar to that described with reference to FIG. 4 or FIG. 5, but the information about risk avoidance is guided along with a risk warning according to a risk determination.

For example, as a result of analyzing the driving information of the vehicle 20 received through the vehicle 40 in the host vehicle 10, the speed of the vehicle 20 is drastically reduced to 0 km / h. When it is determined that the error has occurred, the processor 130 may calculate appropriate risk avoidance information to avoid the dangerous situation and the vehicle 20 that caused the dangerous situation according to the path tracking of each vehicle.

The processor 120 analyzes various preset risk avoidance scenarios, such as deceleration, lane change, speed increase and lane change, and lane change direction, using a risk prediction program based on current risk situation and motion information of the risk factor. A risk avoidance scenario indicating a low risk, for example, a predictive path farthest from a risk factor and a predicted path of another surrounding vehicle can be calculated as risk avoidance information.

Accordingly, the controller 140 may display the danger avoidance information on the display unit 160 and guide the information through the sound output unit 170 if necessary.

Referring to the drawings, for example, when the lane change to the right lane is determined to be the lowest risk as the risk avoidance scenario of the processor 130 is analyzed by the risk prediction program, the control unit 140 is the lane to the right lane. For example, the change may be displayed on the display unit 160 using an arrow G and voice guidance may be provided through the sound output unit 170 to provide risk avoidance information.

7A to 7C illustrate an example of a display screen of the display unit 160.

When the terminal 100 performs the navigation function, the screen of the display unit 160 is displayed as shown in FIG. 7A, for example. In this case, when the user wants to check the motion information of the surrounding vehicles, for example, the screen display mode may be changed to allow the dual mode, that is, the navigation screen and the surrounding vehicle motion information display screen to be simultaneously displayed in different areas as shown in FIG. 7B. have. In addition, the screen display mode may be changed to display only the surrounding vehicle motion information display screen on the full screen as shown in FIG. 7C.

Accordingly, the processor 130 analyzes driving information of the host vehicle 10 and surrounding vehicles, calculates motion information of the surrounding vehicles, and performs a risk prediction program (S320). In addition, the processor 140 may provide risk avoidance information through a risk prediction program in some cases.

Subsequently, the controller 140 displays the movement information of the own vehicle and the surrounding vehicles as graphic elements on the display unit 160 (S330).

In addition, the controller 140 determines whether a dangerous situation occurs according to a risk prediction program of the processor 130 (S340), and when a dangerous situation occurs, the controller 140 identifies and displays the risk factors causing the dangerous situation on the display unit 160. The audio signal is output through the sound output unit 170 to guide the danger (S450). In this case, the controller 140 may control the processor 130 to determine a scenario having the lowest risk among a plurality of preset risk avoidance scenarios through the risk prediction program, and guide the information as risk avoidance information.
