Vehicle accident notification system
[0001] The present invention relates to a vehicle accident notification system, and more particularly to a vehicle accident notification system that detects whether a vehicle accident has occurred in relation to a first vehicle, generates information regarding the accident based on the status information of the first vehicle, and notifies other surrounding vehicles of the accident information through communication with an external server.
[0002] In modern society, automobiles play a vital role in our daily lives, providing transportation convenience while simultaneously emphasizing the importance of road safety. However, automobile accidents are a major issue that undermines this convenience and safety. Accidents can result in casualties and property damage, and prompt response and information sharing at the scene can minimize damage and provide an opportunity to take urgent measures.
[0003] Existing automobile accident management systems primarily focus on collecting and reporting accident information after an accident has occurred. Since these systems provide information only after the accident has already happened, they may limit rapid response at the scene. Furthermore, the lack of features for sharing accident information and cooperating with other vehicles may restrict the ability to quickly share the situation at the accident site and minimize damage.
[0004] Therefore, the present invention aims to present an innovative technology that can enhance road safety by utilizing a vehicle's safety device to quickly share the situation at the accident scene when an accident occurs, and by sharing accident information among surrounding vehicles.

[0027] Hereinafter, some embodiments of the present invention will be described in detail with reference to exemplary drawings. It should be noted that in assigning reference numerals to the components of each drawing, the same components are given the same reference numeral whenever possible, even if they are shown in different drawings. Furthermore, in describing the embodiments of the present invention, if it is determined that a detailed description of related known components or functions would hinder understanding of the embodiments of the present invention, such detailed description is omitted.
[0028] In addition, terms such as first, second, A, B, (a), (b), etc., may be used when describing the components of the embodiments of the present invention. These terms are intended only to distinguish the components from other components, and the essence, order, or sequence of the components is not limited by the terms. Where it is stated that a component is "connected," "combined," or "connected" to another component, it should be understood that the component may be directly connected or connected to the other component, but components may also be "connected," "combined," or "connected" between each component.
[0029] FIG. 1 is an accident processing flowchart according to an embodiment of the vehicle accident notification system of the present invention, and the basic procedure for vehicle accident processing according to the present invention is described as follows with reference thereto.
[0030] According to the vehicle accident notification system of the present invention, when a vehicle breakdown or accident occurs while driving on a road, the vehicle's trunk opens and a safety triangle installed inside the trunk can be deployed. The safety triangle can be deployed automatically and can notify other vehicles approaching from the rear of the accident situation through directional indicators, etc. That is, normally only the trunk opens, but when a vehicle accident occurs, the automatic deployment device for the safety triangle installed inside the trunk is released, allowing the safety triangle to be automatically deployed along with the opening of the trunk. The driver or passenger of the accident vehicle can take follow-up measures after evacuating to a safe place, such as outside the guardrail, in the event of a vehicle accident.
[0031] In addition, accident information can be transmitted via the accident vehicle's mobile terminal or the accident vehicle's terminal. This can be performed through a pre-installed application, and the system can be configured to automatically transmit the information via the application simultaneously with the launch of the application or the automatic deployment of the safety triangle after an accident occurs.
[0032] According to the aforementioned accident handling procedure, vehicles within a first distance, for example, 500m from the accident site (or accident vehicle) can detect the occurrence of an accident by deploying a safety triangle installed on the trunk of the accident vehicle. This can prevent a secondary accident at close range.
[0033] In addition, vehicles within a second distance from the accident site, for example, 500m to 3km, can receive the accident occurrence information transmitted from the accident vehicle through a mobile terminal or a vehicle terminal and detect the occurrence of the accident. Through this, secondary accidents at a distance can be prevented and road detours can be guided.
[0034] In other words, depending on the distance from the accident site, information about vehicle breakdown or accident can be transmitted to rear vehicles in different ways to prevent secondary accidents.
[0035] FIG. 2 is a conceptual diagram of a configuration according to one embodiment of a vehicle accident notification system according to the present invention, FIG. 3 is a flowchart of an accident processing sequence according to the present invention, FIG. 4 is a conceptual diagram of an accident processing according to another embodiment of a vehicle accident notification system according to the present invention, and FIG. 5 is a flowchart of the accident processing sequence of FIG. 4.
[0036] Hereinafter, the present invention will be described with reference to FIGS. 2 to 5.
[0037] The accident measures according to Fig. 1 may apply only when the trunk of the broken vehicle or the accident vehicle is normally opened.
[0038] However, depending on the situation, the trunk opening device may malfunction or fail to operate normally, leaving the trunk unopened. In this case, even if the trunk remains unopened—that is, if the safety triangle is not deployed—vehicles located within the aforementioned first distance must be notified of the accident situation.
[0039] To this end, a broken or accident vehicle, i.e., a first vehicle (10), is configured to include a first communication unit (11), a first detection unit (12), a safety triangle (13), and a first control unit (14), and may further include a second communication unit (15).
[0040] The first communication unit (11) can manage communication between the first vehicle (10) and the external server (40) and perform the role of transmitting accident information to the outside. The first communication unit (11) can be composed of a VCU (Vehicle Communication Unit). The first communication unit (11) can manage and coordinate communication between the first vehicle (10), the external server (40), and, if necessary, surrounding vehicles. This can be implemented by utilizing various communication technologies.
[0041] The first communication unit (11) can handle data communication with an external server (40). Through this, it can transmit generated accident information or vehicle status information to the external server (40) or receive necessary information from the external server (40). Communication with the external server (40) can be done via the Internet or other communication networks.
[0042] Additionally, the first communication unit (11) may include a function to manage communication with surrounding vehicles. Accident information, vehicle status information, etc., can be exchanged between surrounding vehicles to share the situation at the accident scene and cooperate. This can be implemented by utilizing short-range communication technology with surrounding vehicles.

[0046] The first detection unit (12) may be composed of sensors and devices that detect and acquire status information of the first vehicle (10). The first detection unit (12) monitors driving speed, acceleration, vehicle status, etc., and the monitored information can be used for accident detection. The first detection unit (12) may be composed of a VCU (Vehicle Sensor Unit).

[0047] The first sensing unit (12) can detect information about the surrounding environment. That is, it can analyze the driving environment of the vehicle by detecting the location and speed of surrounding vehicles, road conditions, weather, etc.
[0048] The first detection unit (12) can monitor the condition of the vehicle by detecting the engine condition, brake system condition, whether the airbag is activated, etc.
[0049] The first detection unit (12) can detect whether an accident has occurred. For example, it can detect events such as sudden braking, sudden acceleration, or collision while driving, evaluate the possibility of an accident, and generate accident information if necessary.
[0050] The first detection unit (12) can process the detected information and transmit the necessary data to an external server (40) or store it in an internal storage device. Through this, the information can be transmitted externally or utilized for analysis.
[0051] The first detection unit (12) may send an alarm signal to the first control unit (14) or generate a signal to activate a safety device when an accident occurs.
[0052] In this way, the status information of the first vehicle (10) can be monitored in real time through the first detection unit (12), and whether an accident has occurred can be determined, enabling rapid response and information sharing.
[0053] The safety triangle stand (13) is a safety device installed inside the trunk, and in the event of an accident, it can automatically open the trunk and deploy the safety triangle stand (13) to perform the function of indicating and warning the accident scene.
[0054] The safety triangle (13) can automatically open the trunk and deploy the triangle upon receiving a signal from the first control unit (14) when an accident occurs. This allows the accident scene to be quickly marked without the intervention of the driver.
[0055] Each side of the safety triangle (13) may be equipped with a reflective sticker or LED so that surrounding vehicles or pedestrians can recognize the occurrence of an accident by reflecting light even at night or in a dark environment.
[0056] The safety tripod (13) is designed to be safely supported so that it does not easily fall over due to wind or other external factors.
[0057] Although not shown, the safety device detection sensor is a sensor that monitors the status of the safety device, that is, the safety triangle, within the first vehicle (10), and can detect and control whether the device is deployed.
[0058] The safety device detection sensor can detect whether the safety tripod (13) is deployed. It can identify whether the safety tripod (13) is automatically deployed.
[0059] The safety device detection sensor can detect when the safety tripod (13) is manually reduced after an accident and send a signal to the first control unit (14) to update the state of the safety tripod (13).
[0060] The safety device detection sensor can monitor the battery status required for the operation of the safety tripod (13) and, when the battery is low, send a notification to the first control unit (14) and induce it to take necessary measures.
[0061] The first control unit (14) may be a central control unit that generates accident information based on the status information of the first vehicle (10) and controls the operation of the safety triangle (13). The first control unit (14) may perform the role of transmitting accident information to an external server (40) and other vehicles. The first control unit (14) may be composed of a VCU (Vehicle Control Unit).
[0062] The first control unit (14) can perform various functions, such as generating accident information based on the status information of the first vehicle (10), controlling the operation of the safety triangle (13), and managing communication with an external server (40) and surrounding vehicles.
[0063] The first control unit (14) evaluates whether an accident has occurred based on the vehicle's driving state, driving environment, and vehicle state information collected from the first detection unit (12), and can generate accident information if necessary. This information may include the location of the accident, time, and the possibility of an accident.
[0064] The first control unit (14) can control the operation of the safety triangle (13). That is, in the event of an accident, the trunk can be automatically opened and the safety triangle (13) can be automatically deployed by receiving a signal transmitted from the first control unit (14).
[0065] The first control unit (14) can manage data communication with an external server (40) through the first communication unit (11). It can transmit generated accident information or vehicle status information to the external server (40) or receive necessary information from the external server (40).
[0066] The first control unit (14) may include a function to manage communication with surrounding vehicles. It can exchange accident information or vehicle status in real time with surrounding vehicles and cooperate with them.
[0067] The first control unit (14) can process the generated accident information and take measures such as transmitting it to an external server (40) or sending a notification to an output device.
[0068] The first control unit (14) can process detected data and generate necessary control signals to control various devices and manage protocols for communication with an external server (40).
[0069] The first vehicle (10) may be equipped with a communication interface with an external server (40). That is, it may be equipped with an interface capable of data communication with an external server (40) through the first communication unit (11). Through this, accident information can be transmitted externally and information can be received from the server.
[0070] The first vehicle (10) may be equipped with a location information providing system. Location information of the first vehicle can be collected through GPS or other location tracking technology and transmitted, including in accident information.
[0071] The location information provision system can identify the current location of a vehicle and utilize this for accident information and communication with surrounding vehicles. Location information is an essential element for confirming the exact location of the accident scene in the event of an accident and for cooperation with surrounding vehicles. First, the latitude and longitude coordinates of the first vehicle (10) can be identified in real time by utilizing a GPS (Global Positioning System) receiver. GPS provides accurate location information based on satellite signals, and this can be utilized to identify the current location of the vehicle.
[0072] In addition, the exact location of the first vehicle (10) can be calculated based on coordinate information provided by GPS. This allows the location on the road network to be identified through linkage with map data, and the location can be corrected by considering the interaction with the surrounding environment.
[0073] The calculated location information can be transmitted to the first control unit (14) and the first communication unit (11). This information can be used to share the location of the accident site with an external server (40) or surrounding vehicles in the event of an accident.
[0074] In addition, it may be used to set the position of the safety tripod (13) in the event of an accident. Based on the location information, the safety tripod (13) can be placed at an appropriate location at the accident site to mark the accident scene.
[0075] Location information can be used to exchange accident and vehicle status information through communication with surrounding vehicles. Based on location information, accident prevention and response capabilities can be improved through interaction with surrounding vehicles.
[0076] The first vehicle (10) may be equipped with a notification and output system. It may include a system capable of transmitting accident information generated through the first control unit (14) to an external server (40) and another vehicle along with the deployment of the safety triangle (13), and outputting accident information to the occupants if necessary.
[0077] The notification and output system can generate visual or auditory signals to transmit accident information of the first vehicle (10) to the driver and the surrounding environment, and to enable response measures. This system can be used to warn surrounding vehicles and pedestrians of the occurrence of an accident or to guide the driver to take response measures.
[0078] That is, when an accident occurs, the first control unit (14) can quickly generate a notification signal based on the accident information. This can be configured in various forms, such as an alarm sound, a light, or a flashlight.
[0079] In addition, it can guide drivers to immediately grasp accident information and take appropriate action by providing warnings about accident occurrences and response measures.
[0080] In addition, it can serve the role of notifying surrounding vehicles and pedestrians of the occurrence of an accident. By conveying accident information to the surroundings, it can raise the awareness of nearby vehicles and enhance safety at the accident scene.
[0081] In addition, it manages output devices that generate signals and can generate signals at appropriate timing and in a manner.
[0082] In addition, based on information received from an external server (40), a notification message can be generated and the message can be delivered to a driver or nearby vehicle using an output system.
[0083] In addition, to control necessary measures in the event of an accident, a control signal can be generated, for example, a signal to automatically deploy a safety tripod (13).
[0084] The second communication unit (15) manages communication with surrounding vehicles and can perform the role of strengthening accident information sharing and cooperation functions with surrounding vehicles. Therefore, if the first vehicle (10) is configured to include the second communication unit (15), an improved vehicle accident detection and notification system can be established.
[0085] The second communication unit (15) is designed primarily for interaction with surrounding vehicles and can transmit or receive accident information or vehicle status information to or from surrounding vehicles in certain situations.
[0086] The second communication unit (15) can perform data communication with other vehicles located nearby. Through the exchange of information with nearby vehicles, accident information, vehicle status information, driving information, etc., can be shared.
[0087] The second communication unit (15) can transmit accident information or vehicle status information to surrounding vehicles and receive necessary information from surrounding vehicles.
[0088] The second communication unit (15) can perform data processing for communication with surrounding vehicles and manage communication protocols to ensure accurate transmission and reception of data.
[0089] Through the second communication unit (15), interaction with surrounding vehicles can be utilized to guide surrounding vehicles to respond and cooperate immediately in the event of an accident.
[0090] In addition, the second communication unit (15) can be connected to an output device or a display device to generate and transmit necessary messages in order to transmit information to surrounding vehicles. Since communication with surrounding vehicles must be carried out in a safe and secure manner, safety can be enhanced by applying necessary encryption and security technologies.
[0091] The second communication unit (15) can perform the role of improving road safety and strengthening accident prevention and response capabilities through real-time information exchange with surrounding vehicles.
[0092] The second communication unit (15) can communicate with the second vehicle (20) located at the first distance from the first vehicle (10). When the first control unit (14) generates the vehicle accident information, it determines whether the safety triangle (13) is deployed, and if the safety triangle (13) is not deployed, it can transmit the vehicle accident information to the second vehicle (20) through the first communication unit (11).
[0093] Meanwhile, although the first communication unit and the second communication unit were described as being divided into two components, they can be composed of a single module, and the distinction between 'first' and 'second' can be understood as a distinction in terms of communication function.
[0094] The second vehicle (20) may be configured to include an output unit (21), a second detection unit (22), and a second control unit (23). Of course, the second vehicle (20) and the third vehicle (30) described later are described separately for convenience of explanation, and can be considered as the same vehicle, and the components of each vehicle can be configured identically. Therefore, without separate explanation, the components included in the first vehicle (10) may be included in the second vehicle (20) and the third vehicle (30), the components included in the second vehicle (20) may be included in the first vehicle (10) and the third vehicle (30), and the components included in the third vehicle (30) may also be included in the first vehicle (10) and the second vehicle (20).
[0095] The output unit (21) installed in the second vehicle (20) performs the role of displaying or transmitting information to the occupant. This output unit (21) can be configured in various forms and may include various display devices for visually transmitting information to the occupant of the vehicle.
[0096] The output unit (21) is composed of a display screen and can visually display information to the occupants in the second vehicle (20). The display screen can display various information using technologies such as LCD, OLED, and LED.
[0097] Additionally, the output unit (21) can convey information to the occupants of the vehicle by displaying graphic images and text through a display screen. For example, it can display warning messages such as "Accident in progress" or "Caution".
[0098] In addition, the display's color and brightness can be adjusted to ensure information is conveyed clearly under various conditions. In other words, it can be adjusted to maintain visibility even in dark environments at night.
[0099] In addition, it may include multilingual support features that can display information in various languages if necessary.
[0100] In addition, alarm sounds or warning lights can be used in conjunction with the display to provide accident information or warnings to occupants of surrounding vehicles.
[0101] Meanwhile, the display screen may be implemented as a touchscreen to add a function that allows the passenger to directly input or interact, and may include a button or interface that can control and set the operation of the output unit (21).
[0102] The second detection unit (22) is installed in the second vehicle (20) and can obtain second state information from the second vehicle (20). The second detection unit (22) can detect the surrounding environment and collect information to determine the state of surrounding vehicles. Through this, it can provide data for interaction with surrounding vehicles and accident information exchange.
[0103] The second detection unit (22) can collect surrounding environment information using various types of sensors, and may include, for example, radar, LIDAR, ultrasonic sensors, etc.
[0104] Sensors are used to detect and track the location, speed, and direction of surrounding vehicles, thereby enabling the identification of their dynamic status.
[0105] Status information of surrounding vehicles can be extracted by processing data collected from sensors. This information may include the location, speed, acceleration, and driving direction of surrounding vehicles.
[0106] The second detection unit (22) can share status information of surrounding vehicles with an external server (40) or the first vehicle (10) through the second communication unit (15).
[0107] The second detection unit (22) may perform the function of analyzing collected information on surrounding vehicles to determine the possibility of an accident or predict the movement of surrounding vehicles. Additionally, if necessary, it may visually display information on surrounding vehicles through an output unit or display or generate a warning.
[0108] In addition, data collected from various sensors can be integrated to perform the necessary correction process to generate more accurate status information of surrounding vehicles.
[0109] The second control unit (23) is installed in the second vehicle (22) and can determine whether there is a vehicle accident in the driving direction using the vehicle accident information and the second state information received from the second communication unit (15). The vehicle accident information includes the first location information of the first vehicle (10), and the second state information may include the driving vector of the second vehicle (20) and the second location information of the second vehicle (20).
[0110] Additionally, the second control unit (23) can calculate a position vector between the first vehicle (10) and the second vehicle (20) using the first position information and the second position information, and if the angle between the position vector and the driving vector is within a preset angle range, control the output unit (21) to output the vehicle accident information.
[0111] That is, the second control unit (23) determines the possibility of a vehicle accident in the driving direction based on the status information of surrounding vehicles, and if necessary, can transmit accident information to the output unit through cooperation with surrounding vehicles.
[0112] The second control unit (23) can analyze and utilize the status information of surrounding vehicles received from the second communication unit (15). This information may include the location, driving speed, driving direction, etc. of surrounding vehicles.
[0113] The second control unit (23) can determine the possibility of an accident by considering the driving direction of the second vehicle (20) together with the received status information of surrounding vehicles. That is, it can analyze whether there is a potential possibility of an accident in the driving direction by considering the interaction with surrounding vehicles, the driving path, etc.
[0114] The second control unit (23) can calculate the position vector between the first vehicle (10) and the second vehicle (20) and use it to calculate the angle for the driving direction. This calculation can be performed by considering the relative position and driving direction of the first vehicle (10) and the second vehicle (20). That is, the position vector between the first vehicle (10) and the second vehicle (20) can be calculated using coordinate values representing the position of each vehicle. These coordinate values can generally be expressed as X, Y, and Z coordinates. Thus, the position vector of the first vehicle (10) can be expressed as (X1, Y1, Z1), and the position vector of the second vehicle (20) can be expressed as (X2, Y2, Z2).
[0115] In addition, after calculating the position vector, the position difference vector between the two vehicles can be obtained by subtracting it. The position difference vector can be expressed as (ΔX, ΔY, ΔZ). This value can represent the relative distance and direction from the first vehicle (10) to the second vehicle (20).
[0116] Next, the angle relative to the driving direction can be calculated using the position difference vector. This angle is primarily determined using trigonometric functions and represents the angle between the driving direction and the position difference vector. By calculating this angle, it is possible to determine how close the driving direction is to other vehicles.
[0117] The calculated driving direction angle can be compared with a preset angle range.
[0118] If the driving direction falls within a set angle range, for example, it can be determined that the situation with surrounding vehicles matches the driving direction and that the probability of an accident is high.
[0119] In this way, by calculating the position vector and driving direction angle between the first vehicle (10) and the second vehicle (20) to evaluate and determine the possibility of an accident, the function of interaction with surrounding vehicles and accident prevention can be performed.
[0120] That is, referring to FIG. 4, when an accident message is transmitted wirelessly from the accident vehicle, the message can be transmitted not only to the rear vehicle (A) but also to surrounding vehicles (B) traveling in the opposite lane.
[0121] This may cause confusion or misidentification in surrounding vehicles (B) unrelated to the accident vehicle.
[0122] Therefore, the accident message includes GPS values, that is, the accident vehicle includes a first GPS value and the driving vehicle includes a second GPS value, and, for example, the electronic control unit (ECU) of the driving vehicle can perform the following operations.
[0123] First, the straight direction between the accident vehicle and the driving vehicle can be calculated using the first and second GPS values, and the angle value between the calculated straight direction and the driving direction of the driving vehicle can be calculated.
[0124] Accordingly, if the angle value (a) is smaller than the preset angle value, it is determined to be a rear vehicle driving behind the accident vehicle, and a warning message can be output to the driving vehicle.
[0125] In addition, if the angle value (b) is greater than the preset angle value, it is determined to be a surrounding vehicle rather than the rear of the accident vehicle, and a warning message may not be displayed to the driving vehicle. This prevents misidentification or confusion that may occur to surrounding vehicles (B) unrelated to the accident vehicle.
[0126] Additionally, when the calculated driving direction angle is compared with a preset angle range and the driving direction is located within the given angle range, the second control unit (23) can control the output unit (21) to display accident information.
[0127] Additionally, if necessary, the second control unit (23) can communicate with an external server (40) or a nearby vehicle to request additional information or share accident information.
[0128] Meanwhile, the first communication unit (11) may be composed of a terminal mounted on a vehicle or a portable terminal, and the second communication unit (15) may be composed of a short-range communication module.
[0129] Additionally, the first communication unit (11) can transmit the vehicle accident information to the first vehicle (10) and the third vehicle (30) located at a second distance greater than the first distance through an external server (40). The first distance may be a short distance, for example, within 500m, and the second distance may be a longer distance than the short distance, for example, between 500m and 3km.
[0130] The first communication unit (11) can determine the current location of the first vehicle (10) and collect location information of the third vehicle (30), which is another vehicle located at a second distance greater than the first distance from the first vehicle (10).
[0131] The first communication unit (11) has accident information that occurred in the first vehicle (10) and can transmit the accident information it has to the third vehicle (30) through an external server (40).
[0132] The third vehicle (30) can receive accident information of the first vehicle (10) from an external server (40). This information can be transmitted even if the third vehicle (30) is at a relatively long distance from the first vehicle (10).
[0133] The third vehicle (30) can receive accident information from the first vehicle (10) and respond appropriately, thereby allowing the third vehicle (30) to avoid the accident area or pay attention to the accident ahead.
[0134] The present invention can contribute to enhancing road safety and minimizing human and property damage caused by accidents by improving the ability to prevent and respond to vehicle accidents.
