Description

[0001] CROSS-REFERENCE TO RELATED APPLICATIONS

[0002] This application claims priority to and the benefit of Korean Patent Application No. 10-2019-0106759, filed on August 29, 2019, which is hereby incorporated by reference in its entirety. Technical Field

[0003] The present disclosure relates to a vehicle accident notification device, a system including the vehicle accident notification device, and a vehicle accident notification method, and more particularly, to a technology for determining the severity of a traffic accident and providing an accident notification. Background Art

[0004] The statements in this section merely provide background information related to the present disclosure and may not constitute prior art.

[0005] A vehicle accident notification service (eg, eCALL) has been provided which automatically calls a 119 center, a hospital, etc. to provide an accident notification in the event of a traffic accident.

[0006] Such a vehicle accident notification service can be provided by airbag deployment or user's button operation. It is difficult to judge the severity of a traffic accident using only airbag deployment.

[0007] In other words, in the event of an actual collision, when the vehicle collides with a pedestrian or a two-wheeled vehicle, because the vehicle has relatively minor damage than the object (e.g., pedestrian, two-wheeled vehicle, vehicle behind the vehicle, etc.), the airbag of the vehicle is not deployed, and therefore the vehicle accident notification service cannot be enabled.

[0008] However, since casualties often occur even though the airbags are not deployed in the event of an actual accident, it is difficult to quickly rescue and treat the casualties due to a delay in notification of a vehicle accident.

[0009] Furthermore, there are limitations in that the vehicle accident notification service proceeds to the next process only through a consultant and is provided only in some areas. Summary of the invention

[0010] One aspect of the present disclosure provides a vehicle accident notification device that determines the severity of a traffic accident based on vehicle sensing information and vehicle information and automatically provides notification of the accident quickly and accurately, a system including the vehicle accident notification device, and a vehicle accident notification method.

[0041] Some forms of the present disclosure relate to a vehicle accident notification service (eg, eCALL), and discloses a technology for automatically providing a vehicle accident notification service using vehicle information and sensing information rather than simply using airbag deployment or a user request (button input).

[0042] In the following, reference will be made to Figures 1 to 4 Some forms of the disclosure are described.

[0043] Figure 1 is a block diagram illustrating a configuration of a vehicle system including a vehicle accident notification device in some forms of the present disclosure.

[0044] Reference Figure 1 The vehicle accident notification device 100 in some forms of the present disclosure can determine the severity of the traffic accident by interacting with the sensing device 200 and the global positioning system (GPS) receiver 300, and can automatically provide notification of the vehicle accident based on the severity of the traffic accident.

[0045] The vehicle accident notification device 100 can determine whether a vehicle accident has occurred and the severity of the vehicle accident based on the information received from the sensing device 200 (e.g., information about an object outside the vehicle, the amount of impact, etc.) and the vehicle information received from the device in the vehicle through the controller area network (CAN) communication (e.g., vehicle speed signal, vehicle position information, etc.), and can automatically provide a notification of the vehicle accident. In this case, when an impact occurs, the vehicle accident notification device 100 can determine the type of the accident object (e.g., vehicle, pedestrian, two-wheeled vehicle, etc.) together with the vehicle, and can set the level for determining the severity of the vehicle accident differently according to the type of the accident object.

[0046] The vehicle accident notification device 100 may include a communication device 110 , a storage device 120 , a display 130 , and a processor 140 .

[0047] The communication device 110 may be a hardware device implemented using various electronic circuits and transmitting and receiving signals through wireless or wired connections. In some forms of the present disclosure, the communication device 110 may perform inter-vehicle communication through controller area network (CAN) communication, local interconnect network (LIN) communication, Ethernet communication, etc., and may include various communication units for communicating with an emergency center, an accident center, a 119 fire department, a police station, etc. outside the vehicle, such as a mobile communication unit, a broadcast receiving unit such as a digital multimedia broadcasting (DMB) module or a handheld digital video broadcasting (DVB-H) module, a short-range communication unit such as a ZigBee module or a near field communication (NFC) module as a Bluetooth module, and a wireless fidelity (Wi-Fi) unit.

[0048] The storage device 120 may store the sensing result of the sensing device 200 and the impact amount reference value, etc., which are used by the processor 140 to judge the severity of the vehicle accident. In this case, the impact amount reference value may be preset by an experimental value, and may be set differently according to at least one or more of the passenger seating position, collision direction, and / or collision object of the vehicle.

[0049] The storage device 120 may include at least one type of storage medium such as: flash memory, hard disk memory, micro memory, card memory (for example, secure digital (SD) card or extreme digital (XD) card), random access memory (RAM), static RAM (SRAM), read-only memory (ROM), programmable ROM (PROM), electrically erasable PROM (EEPROM), magnetic RAM (MRAM), magnetic disk, and optical disk.

[0050] The display 130 can be controlled by the processor 140 to display a screen when dialing a call for an accident notification and receive an input from the user for stopping the call. In this case, the screen for stopping the call can be output in the form of a pop-up window.

[0051] The display 130 may be implemented as a head-up display (HUD), a combination meter, an audio video navigation (AVN), etc. In addition, the display 130 may include at least one of a liquid crystal display (LCD), a thin film transistor-LCD (TFT-LCD), a light emitting diode (LED) display, an organic LED (OLED) display, an active matrix OLED (AMOLED) display, a flexible display, a curved display, and / or a three-dimensional (3D) display. Some of these displays may be implemented as a transparent display configured as a transparent type or a translucent type to view the outside. In addition, the display 130 may be implemented as a touch screen including a touch panel to be used as an input device in addition to being used as an output device.

[0052] The processor 140 may be electrically connected to the communication device 110, the storage device 120, the display 130, etc., and may electrically control each component. The processor 140 may be a circuit that runs software instructions and may perform various data processing and calculations described below.

[0053] When an impact occurs, the processor 140 may determine whether the impact occurs due to an accident between the host vehicle and surrounding vehicles or due to an accident between the host vehicle and a pedestrian or a two-wheeled vehicle.

[0054] When the impact occurs due to an accident between the host vehicle and surrounding vehicles, the processor 140 may determine whether to automatically provide a notification of the vehicle accident according to the magnitude of the impact, and may attempt to call 112 or 119 to automatically provide a notification of the vehicle accident.

[0055] When the impact occurs due to an accident between the host vehicle and a pedestrian or a two-wheeled vehicle, the processor 140 can identify whether the pedestrian or the person riding on the two-wheeled vehicle is an adult or a minor. When the pedestrian or the person riding on the two-wheeled vehicle is a minor, the processor 140 should automatically provide a notification of the vehicle accident.

[0056] On the other hand, when the pedestrian or the person riding on the two-wheeled vehicle is an adult, the processor 140 may determine whether to automatically provide a notification of a vehicle accident according to the magnitude of the impact.

[0057] The processor 140 may differently set the impact amount reference value according to at least one or more of a passenger seating position of the host vehicle, a collision direction, and a collision object.

[0058] The processor 140 may set the impact amount reference value when the collision object is a person to be lower than the impact amount reference value when the collision object is a vehicle.

[0059] The processor 140 may set the impact amount reference value when the seating position of the passenger of the host vehicle is the same as the collision direction to be lower than the impact amount reference value when the seating position of the passenger of the host vehicle is different from the collision direction.

[0060] When the host vehicle changes its position to an area off the road, deviates from a lane, or crosses a center line, the processor 140 may automatically provide notification of a vehicle incident.

[0061] The sensing device 200 may include a plurality of sensors for sensing an object outside the host vehicle, and may acquire information about the position of the object outside the host vehicle, the speed of the object outside the host vehicle, the moving direction of the object outside the host vehicle, and / or the type of the object outside the host vehicle (e.g., a vehicle, a pedestrian, a two-wheeled vehicle (a bicycle or a motorcycle)). The sensing device 200 may provide the result of sensing the object outside the host vehicle to the vehicle accident notification device 100. The vehicle accident notification device 100 may identify whether the object outside the host vehicle is a vehicle, a pedestrian, or a two-wheeled vehicle based on the information received from the sensing device 200. When the object outside the host vehicle is a pedestrian, the vehicle accident notification device 100 may identify whether the pedestrian is an adult or a minor.

[0062] To this end, the sensing device 200 may include front and rear view cameras 210, a radar 220, a laser radar (LiDAR) 230, a G sensor 240, and the like.

[0063] The front and rear view cameras 210 may include at least one or more cameras and may be mounted on the front, sides and rear of the vehicle to capture the front, sides and rear of the vehicle and provide the captured images to the vehicle accident notification device 100. Therefore, the vehicle accident notification device 100 may identify surrounding vehicles and pedestrians based on the image data received from the front and rear view cameras 210. In this case, the vehicle accident notification device 100 may identify whether the pedestrian is an adult or a minor. In this case, the front and rear view cameras 210 may include a drive video recording system (DVRS) front view camera (FHD) and a surround view monitor (SVM) front and rear view camera (HD). The number of cameras included in the front and rear view cameras 210 may vary according to vehicle specifications. The front and rear view cameras 210 may include two or more cameras.

[0064] The radar 220 and the LiDAR 230 can be loaded on the front, sides and rear of the vehicle to detect the position of external objects existing in front, on both sides and behind the vehicle, the distance to the external objects, whether the external objects are close to the vehicle, etc., and provide the detected information to the vehicle accident notification device 100.

[0065] The G sensor 240 can sense the impact amount of the host vehicle and can provide the sensed information to the vehicle accident notification device 100. The G sensor 240 can calculate the impact amount and impact direction on the X-axis, Y-axis and Z-axis and can detect whether the host vehicle rolls over.

[0066] In addition, the sensing device 200 may further include an ultrasonic sensor, a laser scanner and / or a corner radar, an acceleration sensor, a yaw rate sensor, a torque sensor and / or a wheel speed sensor, a steering angle sensor, etc. to improve the accuracy of detecting external objects.

[0067] The GPS receiver 300 may receive GPS information, and may provide the received GPS information to the vehicle accident notification device 100. In this case, the GPS information may include location information of the host vehicle.

[0068] As described above, in some forms of the present disclosure, vehicle information received through the front and rear view cameras 210, radar 220, LiDAR 230, G sensor 240, GPS receiver 300, and vehicle CAN communication can be used to determine the severity of a traffic accident, and accident notification services can be provided quickly and accurately.

[0069] Hereinafter, a vehicle accident notification method in some forms of the present disclosure will be described in detail. Figure 2 is a flow chart illustrating a vehicle accident notification method in some forms of the present disclosure.

[0070] In the following, it is assumed Figure 1 The vehicle accident notification device 100 performs Figure 2 In addition, Figure 2 In the description, the operations described as being performed by the device may be understood to be controlled by the processor 140 of the vehicle accident notification apparatus 100.

[0071] In S101, the device can be based on Figure 1 The sensing device 200 can identify surrounding vehicles and pedestrians. Figure 1 The image data received by the front and rear view cameras 210 can be used to determine whether the objects around the vehicle are vehicles, pedestrians or two-wheeled vehicles, and whether the pedestrians are adults or minors.

[0072] When the vehicle is traveling based on the vehicle speed signal, the device can determine whether the vehicle has changed its position to an area outside the road, whether the vehicle has deviated from the lane, whether a serious impact has occurred in the vehicle, or whether the vehicle has crossed the center line based on the sensing result of the sensing device 200 and the vehicle information received from the controller in the vehicle (for example, the vehicle speed signal, etc.), and can determine whether an accident has occurred based on the result of the judgment. When it is determined that an accident has occurred, in S102, the device can enter the accident notification mode. In this case, the device can Figure 1 The GPS information received by the GPS receiver 300 can be used to determine whether the vehicle has changed its position to an area outside the road, whether the vehicle has deviated from the lane, or whether the vehicle has crossed the center line, and can be used Figure 1 The G sensor 240 determines whether an impact occurs in the vehicle. In addition, when the impact amount is not received from the G sensor 240 due to a specific reason, the device can use the front and rear view cameras 210 and the GPS receiver 300 to determine the position of the vehicle, and can identify a serious impact in which the vehicle deviates from the lane or an accident in which the vehicle crosses the center line. In this case, the vehicle changing its position to an area outside the road may include the vehicle deviating from the road due to unpredictable reasons such as insufficient driving experience or natural disasters other than the vehicle approaching the shoulder of the road, such as the vehicle parked on the shoulder of the road. In particular, since it is easy for vehicles to approach the seaside or riverside in Korea, but since the seaside or riverside lacks safety facilities such as barriers, guide rails, and night lighting devices, in the event of an accident of sinking into deep water, it is fatal to the user, so even if there is no collision, the device can detect that the vehicle changes its position to an area outside the road, and can determine whether to provide a notification of the accident.

[0073] In S103, the device may determine whether an accident occurs between the host vehicle and surrounding vehicles. When an accident occurs between the host vehicle and surrounding vehicles, in S104, the device may determine whether the impact amount measured by the G sensor 240 is greater than a predetermined first reference value. In this case, the first reference value may be preset by an experimental value.

[0074] When the impact amount is less than or equal to the first reference value, in S105, the device can determine that the current situation is not an emergency and call 112. On the other hand, when the impact amount is greater than the first reference value, in S106, the device can determine that the current situation is an emergency and call 119. In this case, the emergency means that there is an emergency patient. In other words, because there is an emergency patient in an emergency, the device can call 119 and call an ambulance. When it is determined that there is no emergency patient, the device can call 112 and report the accident.

[0075] When trying to call 112 or 119 in S105 and S106, the device can Figure 1 The device may display a screen for calling on the display 130 of the user and may receive an input for stopping the call from the user. In this case, the screen for calling may be displayed in the form of a pop-up window on the display 130 such as a combination meter or an AVN. If unnecessary, the device may disable the function of displaying the screen for calling. In addition, although the impact amount is less than or equal to the first reference value, the device may display a pop-up screen for asking the user whether to call 119.

[0076] Meanwhile, when it is determined that no accident has occurred between the host vehicle and surrounding vehicles, in S107, the device may determine whether an accident has occurred between the host vehicle and a pedestrian (or a two-wheeled vehicle).

[0077] When it is determined that an accident occurs between the host vehicle and a pedestrian (or a two-wheeled vehicle), in S108, the device can determine whether the pedestrian or the person riding on the two-wheeled vehicle is an adult or a minor. In this case, the device can determine whether the pedestrian or the person riding on the two-wheeled vehicle is an adult or a minor based on the image data of the front and rear view cameras 210.

[0078] When the pedestrian is an adult, in S109, the device may determine whether the impact amount is greater than the second reference value. When the impact amount is greater than the second reference value, in S106, the device may determine that the current situation is an emergency and may call 119. On the other hand, when the impact amount is less than or equal to the second reference value, in step S105, the device may determine that the current situation is not an emergency and may call 112.

[0079] When the call 112 or 119 is attempted, in S110 , the device may display a screen for the call on the display 130 , and may receive an input for stopping the call from the user.

[0080] As described above, when a collision accident occurs between the host vehicle and surrounding vehicles, the vehicle accident notification device 100 in some forms of the present disclosure can determine whether to call 119 or 112 based on the impact amount. In addition, when a collision accident occurs between the host vehicle and a minor, the vehicle accident notification device 100 should call 119 and should provide a notification of the accident. When a collision accident occurs between the host vehicle and an adult, the vehicle accident notification device 100 can determine whether to call 119 or 112 based on the impact amount.

[0081] In other words, the vehicle accident notification device 100 in some forms of the present disclosure may automatically provide a notification of the accident and may automatically call an ambulance according to the object and the amount of impact in which the accident occurred.

[0082] exist Figure 2In the embodiment, the vehicle accident notification device 100 calls 119 or 112 according to the object and impact amount of the accident. However, the present disclosure is not limited thereto, for example, the vehicle accident notification device 100 may automatically provide a notification of the accident or not provide a notification of the accident according to the object and impact amount of the accident.

[0083] Figure 3 is a diagram illustrating classification of an impact reference for each area around a vehicle according to a sensing range of a sensing device in some forms of the present disclosure.

[0084] Reference Figure 3 , because the vehicle accident notification device 100 in some forms of the present disclosure uses Figure 1 The radar 220 and the LiDAR 230 are used to identify the position of the target vehicle before the impact, so the corresponding methods can be distinguished by considering the impact of the collision point and direction on the passenger seat despite receiving the same impact amount.

[0085] For example, when the host vehicle collides with the target vehicle, the vehicle accident notification device 100 can divide the area that may cause direct damage to the passenger seat, and can divide and calculate the impact reference. For example, in a state where the passenger is only sitting on the driver's seat, the vehicle accident notification device 100 can set the impact amount reference value of the area 201 in front of the host vehicle to 2, the impact amount reference value of the area 202 behind the host vehicle to 5, and the impact amount reference values ​​of the areas 203 and 204 on both sides of the host vehicle to 4 respectively.

[0086] When a collision occurs in the area 201 in front of the host vehicle with the passenger sitting only on the driver's seat, the vehicle accident notification device 100 may determine that the current situation is an emergency when the impact amount is greater than 2. When the impact amount of the collision in the area 201 in front of the host vehicle is less than or equal to 2, when the impact amount of the collision in the area 202 behind the host vehicle is less than or equal to 5, or when the impact amount of the collision in the areas on both sides of the host vehicle is less than or equal to 4, the vehicle accident notification device 100 may determine that the current situation is not an emergency and may not automatically provide notification of the accident.

[0087] For example, when passengers are sitting on the driver's seat and the front passenger seat, the vehicle accident notification device 100 can set the impact amount reference value of the area 201 in front of the vehicle and the area 203 on the right side of the vehicle to be lower than the impact amount reference value of the area 202 behind the vehicle and the area 204 on the left side of the vehicle.

[0088] In addition, when passengers sit on the driver's seat and the left rear passenger seat, the vehicle accident notification device 100 can set the impact amount reference value of the area 201 in front of the vehicle and the area 204 on the left side of the vehicle to be lower than the impact amount reference value of the area 202 behind the vehicle and the area 203 on the right side of the vehicle.

[0089] As described above, without adding separate hardware for separate accident notification and without considering the deployment of airbags, some forms of the present disclosure can use the vehicle information received through the sensing device pre-loaded in the vehicle and the CAN communication in the vehicle to determine whether an accident has occurred and can provide an accident notification service. In addition, some forms of the present disclosure can provide notification of the accident to take care of pedestrians outside the vehicle, passengers riding on two-wheeled vehicles, etc., as well as the driver in the vehicle.

[0090] In addition, some forms of the present disclosure may set the impact amount reference value for providing the accident notification service differently according to the impact amount or the type of external object (vehicle, pedestrian, two-wheeled vehicle, etc.). Although no collision with an external object occurs, the vehicle accident notification device 100 can identify the position of the vehicle, can determine whether the vehicle deviates from the road or whether the vehicle crosses the center line, and can provide the accident notification service. In addition, some forms of the present disclosure may set the impact amount reference value differently according to the position of the passenger sitting in the vehicle and the collision position (direction), and can determine the degree of emergency of the passenger in an all-round collision.

[0091] Figure 4 is a block diagram illustrating a computing system in some forms of the present disclosure.
