A vehicle sharing terminal system according to an embodiment for solving the above problem includes a terminal device installed inside a vehicle traveling on a road to display dangerous conditions on an electronic map while driving of preceding or surrounding vehicles, and the preceding or surrounding vehicles. When terminal devices installed inside nearby vehicles notify of a dangerous condition such as stopping, slowing down, fog, or flooding, a marker corresponding to the type of the notified dangerous condition is mapped on the electronic map, and the vehicle follows the road. It includes a vehicle driving guidance device that is provided to a terminal device and controlled to be displayed on an electronic map.

The vehicle driving guidance device may display the dangerous state on an electronic map only for terminal devices for which vehicle location sharing is selected in the terminal device.

The vehicle driving guidance device automatically determines the dangerous state of the preceding vehicle when the terminal device of the preceding vehicle operates in a basic mode, and provides the preceding vehicle information provided by the terminal device when the terminal device of the preceding vehicle operates in a manual mode. The dangerous state of the vehicle can be received and judged.

The vehicle driving guidance device controls the preceding vehicle, which is traveling at a specified speed or less, so that when the terminal device of the preceding vehicle operates in the basic mode, a first marker in the shape of a donut is displayed on the electronic map in the terminal device of the following vehicle. , the preceding vehicle that is stopped without moving its position can be controlled so that a second mark in the form of a tripod is displayed on the electronic map in the terminal device of the following vehicle.

The vehicle driving guidance device displays an alarm on the electronic map in the lane where the preceding vehicle in the dangerous condition is located so that the driver can identify the dangerous lane, and displays the alarm on one side of the screen on the electronic map so that the driver can slow down or avoid driving. A distance alarm can be displayed indicating the distance to the preceding vehicle.

In order to solve the above problem, a risk situation sharing method of a vehicle sharing terminal system according to another embodiment is a terminal device installed inside a vehicle driving on the road, and displays the risk status while driving of preceding or surrounding vehicles on an electronic map. A displaying step, and when the vehicle driving guidance device notifies the dangerous state of stopping, slowing down, fog, or flooding in a terminal device provided inside the preceding or surrounding vehicles, a mark corresponding to the type of the notified dangerous state It includes the step of mapping on the electronic map and controlling the road to be displayed on the electronic map by providing it to a terminal device of a vehicle following the road.

The controlling step may provide an electronic map service that displays the dangerous state on an electronic map only to terminal devices for which vehicle location sharing is selected in the terminal device.

The controlling step includes automatically determining the dangerous state of the preceding vehicle when the terminal device of the preceding vehicle operates in a basic mode, and automatically determining the dangerous state of the preceding vehicle provided by the terminal device. The risk status can be received and judged.

In the controlling step, when the terminal device of the preceding vehicle operates in the basic mode, the preceding vehicle traveling at a specified speed or less controls the donut-shaped first mark to be displayed on the electronic map in the terminal device of the following vehicle, The preceding vehicle, which is stopped without moving its position, can control the second marker in the form of a tripod to be displayed on the electronic map on the terminal device of the following vehicle.

The controlling step includes displaying an alarm on the electronic map in the lane where the preceding vehicle in the dangerous state is located so that the driver can identify the dangerous lane, and displaying the preceding vehicle on one side of the screen on the electronic map so that the driver can slow down or avoid driving. A distance alarm can be displayed indicating the distance to the vehicle being driven.

According to an embodiment of the present invention, sharing vehicle location and dangerous situation information is information that informs of dangerous situations between vehicles, thereby helping to prevent and prevent accidents, and in case of stopping due to a collision accident or breakdown while driving, road work and emergency rescue vehicles In cases where driving is impeded by things such as alarm bells, tripods, donuts, and work alarms, you can display alarm bells, tripods, donuts, and work alarms on the electronic map, so vehicles behind can recognize the situation and drive safely, such as slowing down and avoidance. In particular, in serious collisions, turning on emergency lights and If a tripod cannot be installed, dangerous situation information is automatically displayed, which is effective in preventing secondary accidents.

In addition, in the embodiment of the present invention, when bad weather such as fog or heavy rain occurs, it is difficult to secure the front view, making driving difficult and the risk of a collision accident is very high. It is effective in preventing accidents due to bad weather conditions such as fog as it can drive slowly and avoid driving.

Furthermore, in an embodiment of the present invention, before driving a vehicle, the electronic map is scrolled back and forth, left and right, and if fog or flooding conditions are identified along the travel route, the travel route can be changed or the drive can be completely abandoned and a public transportation method can be selected. Therefore, predicted dangerous situations can be prevented in advance.

In addition, the autonomous driving function is a method of avoiding obstacles and dangerous situations after they are detected by lidar, radar, and sensors, so dangerous situations can be recognized only after detection. Therefore, if they are not detected, dangerous situations may be missed. , The embodiment of the present invention is a method of informing each other of dangerous situations while sharing the vehicle location, so by sharing, anyone can fully understand the dangerous situation within the range of the electronic map, and there is no need for equipment such as lidar, radar, or sensors, so there is a possibility of a breakdown.

Like reference numerals refer to like elements throughout the specification.

Hereinafter, specific embodiments will be described with reference to the attached drawings.

FIG. 1A is a diagram showing a vehicle sharing terminal system according to an embodiment of the present invention, FIG. 1B is a schematic diagram of the system of FIG. 1, and FIGS. 2 to 4 are diagrams for explaining the vehicle location information sharing operation for each type of terminal. It is a drawing.

As shown in FIGS. 1A and 1B, the vehicle sharing terminal system 90 according to an embodiment of the present invention includes terminal devices 100 and 105, a communication network 110, a satellite navigation system (GPS) 115, and a vehicle. Includes part or all of the driving guidance device 120.

Here, “including part or all” means that the system 90 is configured by omitting some components such as the satellite navigation device 115, or some or all of the components constituting the vehicle driving guidance device 120. means that it can be integrated and configured into a network device (e.g., wireless switching device, etc.) constituting the communication network 110, and is explained as being fully included to facilitate a sufficient understanding of the invention.

The preceding vehicle terminal device 100 and the following vehicle terminal device 105 include various types of terminal devices for using the electronic map service according to an embodiment of the present invention. For example, the terminal devices 100 and 105 may include a terminal dedicated to an electronic map equipped with a vehicle-specific SIM card (USIM), a navigation terminal capable of displaying an electronic map, or a mobile phone terminal such as a smartphone carried by users. You can. The terminals may be equipped with and run a program, such as an application (hereinafter referred to as an app), for using the electronic map service according to an embodiment of the present invention. The terminal devices 100 and 105 may be installed inside a vehicle 97 or 99 traveling on the road, or the driver may use the smartphone by placing it on a stand or the like. In order to use the service according to the embodiment of the present invention, drivers turn on and operate the terminal device 100 or allow the sharing of location information of the vehicle 97, 99 to use the service according to the embodiment of the present invention. The use of may be possible.

Figure 2 shows sharing of vehicle location information of an electronic map terminal. The electronic map terminal can be equipped with a car-specific USIM linked to services from mobile carriers. Here, the identifier of the car-specific USIM can be the vehicle number. Vehicle location information can be shared by pressing the [Location Sharing] button on the electronic map terminal screen, and pressing the button again can disable the vehicle location information sharing function. When vehicle location information is shared, the vehicle's location can be displayed on an electronic map.

Figure 3 shows vehicle location information sharing using navigation. Location information can be shared by navigation (GPS). For example, the navigation system has a location information sharing menu that allows other vehicles to view location information and dangerous situation information. Here, location information can be shared by pressing the OK button, and location information sharing can be canceled by pressing the Cancel button. The functions in the embodiment of the present invention may be configured to be utilized by applying them to a navigation program.

Figure 4 shows sharing of vehicle location information using a mobile phone terminal. Location information can be shared by mobile phone devices. For example, there is a location information sharing menu on the mobile phone so that other vehicles can also view location information and dangerous situation information. Specifically, location information can be shared between adjacent vehicles, and at the same time, when a dangerous situation occurs, information about the point where the dangerous situation occurs, the cause of the dangerous situation, and the vehicle in which the dangerous situation occurs can be shared. Here, dangerous situations may include various situations such as damage to the road, occurrence of a vehicle accident, fire, appearance of a dangerous structure on the road, occurrence of a broken down vehicle, or flooding of the road.

Here, location information can be shared by pressing the OK button, and location information sharing can be canceled by pressing the Cancel button. The functions in the embodiment of the present invention can be configured to be used by applying them to a mobile phone electronic map app. In the case of a smartphone, etc., an app can be executed to use the service according to an embodiment of the present invention.

As described above, once the sharing of vehicle location information is completed in the terminal devices 100 and 105, while driving on the road, drivers can check the preceding vehicle ( By sharing dangerous situations in real time while the vehicles 97) are driving, the vehicles 99 that are behind can drive slowly or perform evasive driving. As such, the system 90 according to an embodiment of the present invention includes a first step of sharing vehicle location information as shown in FIG. 1b, a second step of mapping the vehicle location on an electronic map and displaying an alarm of a dangerous situation, and It can be seen that there are three stages of operation to slow down and avoid driving while checking the electronic map.

For convenience of explanation, in the embodiment of the present invention, the terminal devices 100 and 105 can be divided into the terminal device 100 of the preceding vehicle 97 and the terminal device 105 of the following vehicle 99. In other words, if a dangerous situation such as stopping, slowing down, fog, or flooding occurs through the terminal device 100 of the preceding vehicle 97, the terminal device 105 of the following vehicle 99 traveling on the same road is notified of the preceding vehicle 97. The dangerous situation of 97 people is displayed in real time on the map of the following vehicle terminal device 105. Of course, these dangerous situations are displayed on the electronic map with different symbols. For example, if a vehicle is stopped due to a collision or breakdown, it may be very dangerous for the user to install a tripod in a place such as a highway, so a tripod notation (or mark) is displayed. Additionally, when the preceding vehicle 97 drives below the designated speed, a donut-shaped mark is displayed on the following vehicle 99 on the electronic map. Of course, the mark can be created in various forms and displayed on the electronic map, and it can be in any form as long as the dangerous situation can be easily recognized by drivers. The leading vehicle 97 and the following vehicle 99 are distinct concepts for convenience of explanation of the invention and may be located in different lanes or may be located in the same lane. Additionally, the leading vehicle 97 and the following vehicle ( 99) may be a concept that includes all adjacent vehicles to notify of a dangerous situation.

Additionally, the terminal devices 100 and 105 can operate in basic mode and manual mode. Here, the mode can be viewed as a shortcut button set to operate in the first or second method. For example, if the terminal devices 100 and 105 operate in the basic mode, this may mean that manual mode operation has not been set, and in this case, the terminal devices 100 and 105 operate in the vehicle 97 and 99. It can also be linked with the electronic control unit (ECU) of In other words, since dangerous situations such as vehicle speed and stopping must be automatically determined, related data can be provided from the vehicle's ECU. Of course, the terminal devices 100 and 105 may be equipped with sensors that can measure direction or speed, such as a gyro sensor or an acceleration sensor, so it may be possible to use them. In addition, in order to determine dangerous situations such as fog or flooding, images taken through the cameras of the terminal devices 100 and 105 may be analyzed, but sensors installed on the lower body or wheels of the vehicle It is possible to detect through , and it is also possible to make a judgment by receiving related information from the server of the Korea Meteorological Administration, such as the Korea Meteorological Administration. Above all, in the basic mode, the terminal devices 100 and 105 automatically determine this dangerous situation while driving on the road and display the dangerous situation of their vehicle on the electronic map of the following vehicle 99. It means you can do it. Of course, for this operation, the terminal devices 100 and 105 may operate in conjunction with the ECU or the vehicle driving guidance device 120 of FIG. 1. The basic mode is an operation mode to prepare for cases where the driver is unable to operate the manual mode due to a vehicle accident.

Additionally, when the terminal devices 100 and 105 operate in manual mode, the driver can manually set a dangerous situation through the terminal devices 100 and 105. In other words, when the driver touches the vehicle or vehicle icon on the terminal device 100 or 105, a settings menu is displayed on the screen, and here, the driver can select an alarm appropriate for the situation. Through this, the dangerous situation of the relevant vehicle can be displayed on the terminal device 105 of the following vehicle 99. Of course, the operations of basic mode or manual mode can be mixed and operated. For example, if the driver sets the manual mode, but a major accident occurs, there is a high possibility that the driver will not be able to notify the driver of a dangerous situation. Therefore, when there is no input action from the driver after the vehicle stops or a major accident is predicted through an impact sensor, etc., of course, this can be known through the vehicle's operation data provided by the ECU, and in this case, it operates in the basic mode for automatic judgment. Anything is possible. Accordingly, embodiments of the present invention will not be specifically limited to any one method.

Of course, in addition to this, the terminal devices 100 and 105 can display dangerous situations while driving in various forms on the electronic map. A representative example is to distinguish and display lanes on an electronic map and set a lane alarm function on the electronic map so that drivers can identify dangerous lanes in real time. To this end, specific lanes can be turned red and restored to their original state once the dangerous situation has been resolved. Colors or markings can be made in various ways. Additionally, the terminal devices 100 and 105 can perform a distance alarm function. For example, a distance alarm screen may be displayed on one side of the electronic map of the terminal devices 100 and 105, for example, red for within 20m from the location where a dangerous situation occurred, yellow for within 1km, and green for within 2km. It can be displayed in the form. This distance function can automatically implement the distance function when an accident occurs within 2km based on the driving direction. Of course, the distance standard for notification may change, so it will not be specifically limited to any one. For example, it may be most desirable to be able to guide the following vehicle 99 to a detour road. In other words, if a detour is found within 1 km, guidance can be provided at this point, and if a detour is found within 2 km, guidance can be provided based on that point in time. Since this can be done in various ways depending on the intention of the service provider, etc., embodiments of the present invention will not be specifically limited to any one form. Other details will be discussed later.

The communication network 110 includes both wired and wireless communication networks. For example, a wired or wireless Internet network may be used or linked as the communication network 110. Here, the wired network includes Internet networks such as cable networks and public switched telephone networks (PSTN), and the wireless communication network includes CDMA, WCDMA, GSM, EPC (Evolved Packet Core), LTE (Long Term Evolution), and Wibro networks. It means including. Of course, the communication network 110 according to an embodiment of the present invention is not limited to this, and can be used as an access network for a next-generation mobile communication system to be implemented in the future, for example, a cloud computing network in a cloud computing environment, a 5G network, etc. For example, if the communication network 110 is a wired communication network, the access point within the communication network can connect to the telephone company's exchange office, etc., but in the case of a wireless communication network, data is processed by connecting to the SGSN or GGSN (Gateway GPRS Support Node) operated by the communication company, or Data can be processed by connecting to various repeaters such as BTS (Base Transceiver Station), NodeB, and e-NodeB.

Communication network 110 may also include access points. Access points may include small base stations, such as femto or pico base stations, which are often installed in buildings. Here, femto or pico base stations are classified according to the maximum number of preceding vehicle terminal devices 100 or following vehicle terminal devices 105, etc., that can be connected in the classification of small base stations. Of course, the access point may include a short-range communication module for performing short-range communication such as ZigBee and Wi-Fi with the user terminal 100. Access points can use TCP/IP or RTSP (Real-Time Streaming Protocol) for wireless communication. Here, in addition to Wi-Fi, short-range communication can be performed using various standards such as Bluetooth, Zigbee, infrared (IrDA), RF (Radio Frequency) such as UHF (Ultra High Frequency) and VHF (Very High Frequency), and ultra-wideband communication (UWB). You can. Accordingly, the access point can extract the location of the data packet, designate the best communication path for the extracted location, and forward the data packet to the next device, for example, the vehicle driving guidance device 120, along the designated communication path. Access points can share multiple lines in a typical network environment and may include, for example, routers, repeaters, and repeaters.

The satellite navigation device 115 can track the positions of the preceding vehicle 97 and the following vehicle 99 according to an embodiment of the present invention at the request of the vehicle driving guidance device 120 of FIG. 1. Of course, location tracking of the vehicles 97 and 99 may be accomplished by the terminal devices 100 and 105 provided therein. For example, when location sharing is selected in the preceding vehicle terminal device 100 or the following vehicle terminal device 105 to use the service according to an embodiment of the present invention, the location sharing request is sent to the vehicle driving guidance device of FIG. It can be transmitted to (120), and accordingly, the vehicle driving guidance device 120 is connected to a vehicle equipped with the preceding vehicle terminal device 100 or the following vehicle terminal device 105 through communication with the satellite navigation device 115 ( 97, 99) will be tracked. The satellite navigation device 115 generates location information about the current location, such as latitude and longitude information, in the form of coordinate values through communication with the terminal device 100, 105 or the vehicle 97, 99, and provides the vehicle driving guidance device 120 ) can be sent to. Of course, such location information is possible because the terminal devices 100 and 105 are equipped with a GPS module for GPS communication, and therefore the location information is provided to the vehicle driving guidance device 120 through the terminal devices 100 and 105. Since any number of shapes are possible, embodiments of the present invention will not be particularly limited to any one form. Location information of the vehicles 97 and 99 is provided through the terminal devices 100 and 105, but when registering as a member to use the service, identification information of the vehicles 97 and 99, such as vehicle number, is provided through the terminal devices 100 and 105. By providing , it will be possible to recognize which terminal devices 100 and 105 are installed on which vehicles 97 and 99.

Above all, even if the satellite navigation device 115 is not used in the embodiment of the present invention, the preceding vehicle terminal device 100 and the following vehicle terminal device 105 may include sensors such as a gyro sensor or an acceleration sensor. It may be possible to track the positions of the preceding vehicle 97 and the following vehicle 99 through It may be possible to track your location. For example, if the vehicle is communicating with the vehicle's terminal device at a base station where the vehicle is currently located, and the vehicle leaves the communication range, communication can be established with a new base station in charge of communications in the area outside the area, and the base station and terminal device are connected to each other. When performing communication, the distance can be calculated through the communication signal strength, and therefore, if the location information of the base station is known, it may be possible to ultimately track the location of the vehicle by reflecting the distance calculated based on this. Of course, at this time, it is also possible to use the information from the gyro sensor to know the exact direction of the vehicle based on the base station. Therefore, the embodiment of the present invention will not be particularly limited to the application of the satellite navigation device 115.

The vehicle driving guidance device 120 operates so that terminal devices 100 and 105 provided in vehicles 97 and 99 traveling on the road can share dangerous situations of other vehicles. For example, the vehicle driving guidance device 120 may share vehicle location information and then display vehicle location mapping and a dangerous situation alarm on an electronic map. Accordingly, the following vehicle 99 can drive slowly and avoidably while checking the dangerous situation of the preceding vehicle 97 on the electronic map. Of course, in this process, the vehicle driving guidance device 120 may receive different notifications of dangerous situations depending on whether the terminal devices 100 and 105 provided in the vehicles 97 and 99 operate in the basic mode or the manual mode. there is. Of course, drivers of the vehicles 97 and 99 may not be aware of this. However, if different dangerous situations are displayed in the vehicles 97 and 99 located in the same place, confusion among drivers occurs, so the vehicle driving guidance device 120 trusts one dangerous situation and Risk situations can be unified. In other words, when operating in the basic mode, of course, this can be automatically recognized when there is no manual mode setting in the terminal devices 100, 105, and the vehicle driving guidance device 120 automatically detects dangerous situations according to the operation of the basic mode. It can be judged as follows. For example, when speed data is provided through the electronic control unit (ECU) of the vehicle (97, 99) or sensor data is provided through the acceleration sensor of the terminal device (100, 105), the speed of the vehicle is detected. can do. Therefore, if the speed is below the designated speed, for example, if the vehicle is traveling at a speed of 30 km or less, the situation can be displayed on the electronic map of the vehicle. Marks related to speed can be displayed in the shape of a donut.

In addition, the vehicle driving guidance device 120 can perform various operations. For example, in manual mode, when the driver of the vehicle (97, 99) notifies through the terminal device (100, 105) that the vehicle is stopped due to a collision or breakdown, the vehicle driving guidance device (120) In relation to this, ensure that the tripod symbol is displayed on the electronic map. Of course, for this purpose, a tripod marker can be created, matched to the electronic map, and transmitted to the terminal devices 100 and 105. In addition, the vehicle driving guidance device 120 can show on an electronic map which lane the vehicles 100 and 105 in a dangerous situation are located. Therefore, when a dangerous situation occurs in the vehicles 100 and 105 located in a specific lane, the lane alarm function is activated on the electronic map. For example, an alarm can be displayed by marking the lane area in red. In addition, as mentioned above, if a dangerous situation occurs within, say, 2 km, the vehicle driving guidance device 120 activates the distance alarm function to display, for example, the distance to the accident vehicle on one side of the electronic map currently displayed on the screen. Make the driver aware. For example, the distance to an accident vehicle is known as the location of two points based on the location information of the accident vehicle and the location information of the currently driving vehicle, so it may be possible to calculate the distance using a distance formula. For this purpose, an arithmetic program that calculates the distance may be applied.

Of course, so far, it has been explained that the electronic map service is provided only to terminal devices 100 and 105 that allow drivers to share the vehicle's location. However, in an embodiment of the present invention, it is possible to randomly select vehicles driving in the same place and display them on the map so that drivers can conveniently view the electronic map on the terminal devices 100 and 105. For example, vehicles in which incidents or accidents occur can be displayed on the electronic map, or vehicles where accidents are expected to occur based on the driver's driving habits, driving style, and driving experience can be displayed on the electronic map. You can. Of course, for this purpose, a deep learning program of artificial intelligence (AI) can be used to collect and analyze big data related to vehicle operation. In an embodiment of the present invention, 20 vehicles should actually be displayed on one screen of the electronic map, but in order to increase visibility, sampling can be done at random, in other words, the target can be summarized and displayed on the screen, and at this time, various driver's information It may be possible to select the target using .

In addition to the above, the terminal devices 100 and 105 and the vehicle driving guidance device 120 of FIG. 1 can perform various operations, and other details will be looked at in more detail through FIGS. 5 to 16. .

Figures 5 to 13 are diagrams showing various examples of sharing dangerous situations and displaying alarms on an electronic map.

Figure 5 shows risk situation sharing and alarm display on the electronic map. When the vehicle's location information is shared, the location of the vehicle can be displayed on the electronic map along with an alarm ringtone for 3 seconds on the electronic map terminal. Only the tripod display and donut display can be set to basic mode and manual mode. In the basic mode, if the vehicle is traveling less than 30 km/h, a donut alarm display may appear, and if the vehicle stops due to a collision or breakdown and there is no change in the vehicle location, a tripod alarm display may automatically appear. Manual mode may mean that the driver inputs all alarm displays by directly setting them.

Figure 6 shows dangerous situation alarm settings in relation to dangerous situation sharing and alarm display on the electronic map. Only the tripod sign, which indicates the vehicle is stopped, and the donut sign, which indicates slow movement, can be set to basic mode or manual mode. If it is not set to manual mode, it will operate in basic mode and a dangerous situation alarm can be automatically displayed by recognizing changes in location depending on driving speed. Therefore, it is effective in cases where it is physically impossible to turn on emergency lights or install a tripod due to a serious collision accident. Figure 6 shows the display in manual mode when stopped, slow moving, foggy, or flooded. When you touch the vehicle or screen, a settings menu appears, where you can select an alarm that suits the situation.

Figure 7 shows the lane alarm function in relation to sharing dangerous situations and displaying alarms on the electronic map. The electronic map has a lane alarm function, allowing you to identify dangerous lanes in real time. When a tripod alarm is displayed on the electronic map by sharing a dangerous situation, the corresponding lanes can be inverted to red to display the alarm. The red alarm sign can be restored to its original state when passing through the danger lane or when the dangerous situation is resolved.

Figure 8 is a diagram to explain the distance alarm function in relation to sharing dangerous situations and displaying alarms on the electronic map. The electronic map has a distance alarm function, so you can check the distance in real time. Red is displayed within 200M from the location where a dangerous situation occurs, yellow is displayed within 1Km, and green is displayed within 2KM, so vehicles behind can safely slow down and avoid driving.

Figure 9 is a diagram for explaining the collision prevention sensor bar in relation to sharing dangerous situations and displaying alarms on the electronic map. The red square border that appears on the electronic map represents your vehicle and the impulse prevention sensor bar. The role of the collision prevention sensor bar is to prevent collisions and collisions by sounding an alarm when the edge of your vehicle touches another vehicle on the electronic map. According to traffic laws, the width of the lane is more than 3m, so the thickness of the border of the anti-collision sensor bar is 30cm. In other words, the vehicle driving guidance device 120 of FIG. 1 can control a red square border to be displayed on the electronic map when a collision between the driver's vehicle is expected. Since various methods are possible for determining the driving direction or attitude of a vehicle, such as using data from a gyro sensor, embodiments of the present invention will not be specifically limited to any one type.

Figure 10 is a diagram to explain the fog alarm function in relation to sharing dangerous situations and displaying alarms on the electronic map. If driving is difficult due to fog, you can notify others of the dangerous fog situation. If you select a fog situation in the terminal's alarm settings, a fog alarm will be displayed on the electronic map. Drivers can drive slowly and avoid driving while looking at the electronic map. Before driving a vehicle, you can scroll the electronic map and if fog conditions are identified along the route, you can change the route in advance or select a public transportation method.

Figure 11 is a diagram to explain the flooding alarm function in relation to sharing dangerous situations and displaying alarms on the electronic map. If driving is difficult due to flooding, you can notify others of the risk of flooding. If you select a flooding situation in the terminal alarm settings, a flooding alarm can be displayed on the electronic map. Drivers can scroll the electronic map forward, backward, left, and right to determine the flooding situation and select a detour to take a safe route against flooding. Before driving a vehicle, you can scroll through the electronic map and if flooding conditions are identified along the route, you can change the route in advance or select a public transportation method.

Of course, in the case of a fog or flooding situation as shown in FIGS. 10 and 11, the situation can be automatically determined by analyzing the captured video captured through the camera of the terminal device 100, 105, but the black box can be connected to the black box. It may be possible to analyze and use captured images, and in this process, dangerous situations can be known by linking to the Korea Meteorological Administration server and referring to weather information. Therefore, the vehicle driving guidance device 120 of FIG. 1 can be used to control fog in various ways. It will be possible to determine the situation and flood situation and display corresponding marks on the electronic map.

Figure 12 shows sharing of fog situation in relation to risk situation information sharing and alarm display by CCTV. When a service that shares dangerous situations recognized by artificial intelligence CCTV with the terminal is started, the electronic map receives dangerous situation information in real time. Figure 12 shows an example of receiving and displaying dangerous situation information in a fog situation. When drivers check the fog situation shown on the electronic map, they plan to drive slowly or take a detour in advance.

Figure 13 shows sharing of flooding situations in relation to sharing of dangerous situation information and alarm display by CCTV. When a service that shares dangerous situations recognized by artificial intelligence CCTV with the terminal is started, the electronic map receives dangerous situation information in real time. Figure 13 shows an example of receiving and displaying dangerous situation information in a flood situation. When drivers check the fog situation shown on the electronic map, they plan to drive slowly or take a detour in advance.

Figure 14 is a diagram for explaining response to a situation where the vehicle has stopped. A vehicle stopping situation can result in a dangerous situation due to a collision or breakdown. Drivers who notice that a collision accident occurred in the third lane of the road ahead and that the vehicle ahead is not driving share location information and refer to the electronic map terminal to slow down and change lanes. Figure 14 is an example of a driver changing lanes from 3 lanes to 2 lanes.

Figure 15 is a diagram for explaining response to bad weather situations. Bad weather can mean fog or flooding. When thick fog occurs ahead, drivers cannot look ahead, making it very difficult to drive safely. Additionally, flooding situations can easily put drivers and vehicles at risk. In this case, you can share location information, set an alarm, and drive slowly and avoid driving while looking at the electronic map. It can be developed into artificial intelligence (AI) autonomous driving by utilizing real-time driving conditions on the electronic map. For example, the vehicle driving guidance device 120 in FIG. 1 can comprehensively determine the current traffic situation by analyzing data related to vehicle driving or by further referring to traffic situation data provided by the Korea Expressway Corporation, etc., and thus flood, etc. In dangerous situations, the driver can be notified of the current situation on the screen and forced to switch to autonomous driving mode to quickly evacuate the vehicle.

Figure 16 is a diagram to explain the display of a situation mapped on an electronic map by sharing location and dangerous situation. Figure 16 (a) shows the driving situation mapped on the electronic map by sharing the vehicle, and Figure 16 (b) shows the vehicle driving slowly due to bad weather (e.g. fog, heavy rain, heavy snow, etc.). . Since the electronic map for service provision according to an embodiment of the present invention may be provided with various screens, such as an animation form, the present invention will not be specifically limited to any one form.

FIG. 17 is a block diagram illustrating the detailed structure of the vehicle driving guidance device of FIG. 1.

As shown in FIG. 17, the vehicle driving guidance device 120 according to an embodiment of the present invention includes a communication interface unit 1700, a control unit 1710, a vehicle driving guidance unit 1720, and a portion of the storage unit 1730. or includes all.

Here, “including part or all” means that the vehicle driving guidance device 120 is configured by omitting some components, such as the storage unit 1730, or that some components, such as the vehicle driving guidance unit 1720, are configured by the control unit ( 1710), it means that it can be formed by being integrated with other components such as

The communication interface unit 1700 communicates with the terminal devices 100 and 105 and the satellite navigation device 115, respectively, via the communication network 110 of FIG. 1. In the process of performing communication, the communication interface unit 1700 performs operations such as modulation/demodulation, muxing/demuxing, encoding/decoding, and scaling to convert resolution. Since this is obvious to those skilled in the art, further explanation is omitted. The terminal devices 100 and 105 installed in the vehicles 97 and 99 may be of various sizes, such as 7 inches, 10 inches, and 15 inches. Therefore, resolution conversion can be done to provide an electronic map optimized for the size of such an imaging panel.

The communication interface unit 1700 performs communication with the satellite navigation device 115 under the control of the control unit 1710 when location information sharing is selected in the preceding vehicle terminal device 100 or the following vehicle terminal device 105 of FIG. 1. The locations of vehicles 97 and 99 equipped with the corresponding terminal devices 100 and 105 can be tracked. In this process, the communication interface unit 1700 may receive the location tracking result of the vehicle 97 or 99 or the terminal device 100 or 105 together with the device identification information and provide the result to the control unit 1710 of FIG. 1. .

Additionally, the communication interface unit 1700 may transmit electronic map data to the preceding vehicle terminal device 100 and the following vehicle terminal device 105 under the control of the control unit 1710. Of course, the electronic map data may be stored in the terminal devices 100 and 105, so in this case, the communication interface unit 1700 transmits only the identification information, location information, and risk situation information of the vehicles 97 and 99, thereby providing real-time control of the vehicle. An electronic map with changing locations and dangerous situations can also be displayed on the screen. However, in the embodiment of the present invention, the computing power of the terminal devices 100 and 105 may be low, so the electronic map data is transferred from the vehicle driving guidance device 120 of FIG. 1 to the terminal device 100 so that the data can be simply displayed on the screen. , 105), it is desirable to transmit it.

The control unit 1710 is responsible for the overall control operation of the communication interface unit 1700, the vehicle driving guidance unit 1720, and the storage unit 1730. Typically, the control unit 1710 can operate the terminal devices 100 and 105 in the basic mode or manual mode depending on whether manual mode information is provided from the terminal devices 100 or 105 through the communication interface unit 1700. . When passive mode information is provided, the terminal devices 100 and 105 are operated in manual mode, but if there is no separate information transmission, they can be operated in basic mode. Of course, if basic mode information is transmitted, it is also possible to operate in basic mode.

When operating in the basic mode, the control unit 1710 performs an operation to automatically determine the dangerous situation of the currently driving vehicles 97 and 99. For example, when driving slowly, speed data is provided from the vehicles 97 and 99 or the terminal devices 100 and 105 to determine the speed of the currently driving vehicle. In addition, when operating in manual mode and the driver is notified of a fog situation, it can be shown on the electronic map of the following vehicle 99 that the relevant area is in a fog situation based on the information. Of course, the fog situation can be marked on all vehicles 97 and 99 passing through the area as shown in FIG. 10, but it is also possible to display it on one side of the screen as shown in FIG. 12. To perform these operations, the control unit 1710 may operate in conjunction with the vehicle driving guidance unit 1720.

The vehicle driving information unit 1720 provides a service for sharing dangerous situations of vehicles driving on the road. To this end, the vehicle driving information unit 1720 shares the location information of vehicles driving on the road and determines the dangerous situation of the vehicles 97 and 99 driving according to the location information and displays it on the electronic map that drivers see. . In other words, the vehicle driving information unit 1720 can be viewed as generating electronic map data that allows you to see at a glance the dangerous situations of vehicles driving on the road. Of course, in order to generate such electronic map data, the vehicle driving information unit 1720 can execute a GUI program. When a specific vehicle stops, a preset tripod marker is matched to the vehicle so that other drivers can see it on the electronic map. Also, if a collision or breakdown occurs in a specific vehicle and the vehicle is stopped, it is determined and The donut-shaped mark that has been set is matched to the vehicle in question so that other drivers can see it on the electronic map.

Of course, in addition to this, the vehicle driving information unit 1720 can perform various operations. As mentioned above, the vehicle driving information unit 1720 can typically perform operations in basic mode and manual mode. When the vehicles 97 and 99 operate in the basic mode, the dangerous situation of the vehicles 97 and 99 can be automatically determined by analyzing speed data or captured images. Of course, the vehicle driving information unit 1720 may apply a deep learning program of artificial intelligence in the operation of the basic mode and manual mode. For example, the reliability index can be reflected by analyzing the driver's driving habits. Information from drivers with good driving habits or a high reliability index is more trusted. Therefore, the vehicle driving information unit 1720 can collect big data related to drivers' driving and then analyze it to calculate a reliability index, and based on this, fog or flooding situations can be precisely determined. For example, when different dangerous situation information is transmitted from terminal devices 100 and 105 passing through the same area or adjacent areas, the dangerous situation information of a driver with a high reliability index is trusted, so the dangerous situation information is incorrectly based on this. The dangerous situation indicator for the transmitted vehicle can also be changed and displayed on the electronic map.

Furthermore, the vehicle driving information unit 1720 displays the dangerous situations of the vehicles 97 and 99 on the electronic map, but it is also possible to reduce the number of vehicles displayed on the screen to improve readability for drivers. To this end, if the vehicle driving information unit 1720 determines that the number of vehicles passing through the same area is too large, the number can be adjusted depending on the size of the screen, but the number can be randomly reduced and displayed on the screen. It can focus on vehicles that are expected to have an incident or accident, or it can select the target and display it on the screen by comprehensively considering the driver's driving habits or experience. Since various methods are possible, embodiments of the present invention will not be specifically limited to any one form.

The storage unit 1730 can temporarily store various types of data processed under the control of the control unit 1710 and then provide the data to the vehicle driving information unit 1720. For example, when the driver notifies the current dangerous situation in the terminal devices 100 and 105, the information is temporarily stored in the storage unit 1730 and then provided to the vehicle driving information unit 1720 to provide an electronic map of the vehicle. can be updated.

The communication interface unit 1700, control unit 1710, vehicle driving guidance unit 1720, and storage unit 1730 of FIG. 17 according to an embodiment of the present invention are composed of hardware modules that are physically separated from each other, but each module is It will be possible to store software to perform the above operations internally and execute it. However, the software is a set of software modules, and each module can be formed as hardware, so there will be no particular limitation on the configuration of software or hardware. For example, the storage unit 1730 may be hardware, such as storage or memory. However, since it is possible to store information through software (repository), the above content will not be specifically limited.

Meanwhile, as another embodiment of the present invention, the control unit 1710 may include a CPU and memory, and may be formed as a single chip. The CPU includes a control circuit, an arithmetic unit (ALU), an instruction interpretation unit, and a registry, and the memory may include RAM. The control circuit performs control operations, the operation unit performs operations on binary bit information, and the command interpretation unit includes an interpreter or compiler, which can convert high-level language into machine language and machine language into high-level language. , the registry may be involved in software data storage. According to the above configuration, for example, at the beginning of the operation of the vehicle driving guidance device 120, the program stored in the vehicle driving guidance unit 1720 is copied, loaded into memory, that is, RAM, and then executed, thereby increasing the data operation processing speed. can increase rapidly. In the case of deep learning models, they can be loaded into GPU memory rather than RAM and executed by accelerating the execution speed using GPU.

The medium risk status is displayed on the electronic map (S1800). As a dangerous state, the terminal devices 100 and 105 may typically display signs related to slowing down, stopping, fog, flooding, etc. Here, the terminal devices 100 and 105 can be electronic map terminals (including vehicle USIM), navigation, mobile phone terminals, etc., and the terminal devices 100 and 105 can provide services by selecting vehicle location information sharing. Accordingly, vehicle location information sharing may be activated. And the terminal devices 100 and 105 map the vehicle's location information onto a real-time electronic map. Sharing vehicle location information of vehicles driving behind is an alarm notifying of a dangerous situation. When the location information of driving vehicles is mapped in real time on an electronic map, drivers drive safely while referring to the electronic map.

In addition, when the vehicle driving guidance device 120 notifies the terminal device 100 provided inside the preceding or surrounding vehicles of a dangerous state such as stopping, slowing down, fog, or flooding, the vehicle driving guidance device 120 provides a response corresponding to the type of the notified dangerous state. The mark is mapped on the electronic map and provided to the terminal device 105 of the vehicle following on the road, so that it is displayed on the electronic map (S1810).
