[0026] FIG. 1 is a view showing a vehicle accident notification system according to one embodiment of the present invention.

[0027] Referring to FIG. 1, the vehicle accident notification system according to one embodiment of the present invention includes a user terminal 10 and a vehicle accident notification server 20.

[0028] According to the vehicle accident notification system of one embodiment of the present invention, when an accident occurs in a vehicle on which a user gets, the accident occurrence is transmitted from the user terminal 10 to the vehicle accident notification server 20, the vehicle accident notification server 20 transmits the vehicle accident occurrence to a preset accident response organization such as an insurance company, an emergency rescue organization such as 911, a vehicle towing company, and other emergency contacts set by the user, so as to facilitate handling in response to the accident.

[0029] The vehicle accident notification server 20 and the user terminal 10 constituting the vehicle accident notification system may be connected to each other through a network. The network refers to a connection structure for allowing information exchange between nodes such as terminals and servers, and examples of the network include a 3rd generation partnership project (3GPP) network, a long term evolution (LTE) network, a world interoperability for microwave access (WIMAX) network, the Internet, a local area network (LAN), and a wireless local area network (Wireless LAN), a wide area network (WAN), a personal area network (PAN), a Bluetooth network, a satellite broadcasting network, an analog broadcasting network, a digital multimedia broadcasting (DMB) network, and the like, but are not limited thereto.

[0030] FIG. 2 is a block diagram showing a user terminal of FIG. 1.

[0031] Referring to FIG. 2, the user terminal 10 includes a sensor module 110, a communication unit 120, a memory 130, a control unit 140, and a user interface 150.

[0032] The user terminal 10 may include various types of terminals or electronic equipment, such as a mobile phone, a smart phone, and a tablet PC, capable of data communication via wired or wireless. The user terminal 10 may be provided while being carried by the user in the vehicle or mounted inside the vehicle.

[0033] The sensor module 110 is provided in the user terminal 10 to detect a change in movement state of the vehicle. The sensor module 110 may include a shock sensor module for detecting a shock applied to the vehicle. For example, the shock sensor module may be provided as an acceleration sensor. The acceleration sensor may be provided as a 3-axis acceleration sensor to detect an up-down shock amount, a front-rear shock amount, and a left-right shock amount. The acceleration sensor may be controlled such that sensitivity of a sensor value is adjusted according to the speed of the vehicle. The acceleration sensor may be controlled such that the sensitivity of the front-rear shock amount or the left-right shock amount is adjusted to be greater than the sensitivity of the up-down shock amount, so as to improve the discrimination of determination on the accident. For example, when a vehicle crosses a speed bump, the up-down shock amount of the vehicle is greater than the left-right shock amount or front-rear shock amount. Accordingly, in the case of a slow mode, the sensitivity of the up-down shock amount may be controlled to be set lower than the left-right shock amount or the front-rear shock amount.

[0034] In addition, the shock sensor module may include an acceleration sensor and a gyro sensor. Accordingly, the accuracy of detecting a state such as a speed change of the vehicle during driving, sudden braking of the vehicle, or sudden rotation or overturn of the vehicle due to a shock may be improved. For example, the type of overturn may be determined using changes in longitudinal speed and changes in lateral speed of the vehicle. In order to more accurately determine the type of overturn, at least one of a roll rate detected by the gyro sensor and a vertical acceleration detected by the acceleration sensor may be used for the determination. The type of overturn may be determined as a ramp mode when the vehicle turns while either a right or left side of the vehicle is driving on a ramp; a ditch mode when the vehicle enters and turns on a downward ramp such as a dike; a bump mode when the vehicle turns in the lateral direction on a stepped part such as a curb stone on the road; and a sand mode when the vehicle enters a road surface, such as a sandy road, having a large friction coefficient, and turns due to hindrance in the lateral direction, and may be determined as an auxiliary mode when it is not determined by any type among the above types of overturn determinations.

[0035] The sensor module 110 may include a position sensor module. The position sensor module detects changes in position of the vehicle. In addition, the speed of the vehicle may be calculated through the changes in position of the vehicle detected by the position sensor module. The position sensor module may be a GPS sensor.

[0036] The communication unit 120 may be provided to enable wireless data communication through the network, so as to transmit and receive data with the vehicle accident notification server 20.

[0037] The memory 130 may store various data such as a client program for using the vehicle accident notification service, data generated for operating the client program, data received from the vehicle accident notification server 20, and a detected value of sensor module 110. In addition, the memory 130 may store pattern information. The pattern information is provided in the form of a pattern of data for the basis of determining whether the vehicle has the accident. In addition, the pattern information may be updated through the data transmitted from the vehicle accident notification server. The pattern information includes shock amount pattern information. The shock amount pattern information is provided in a shock amount pattern form when the vehicle is in a normal state or an abnormal state. The shock amount pattern information may include the pattern forms of the up-down shock amount, the front-rear shock amount, and the left-right shock amount. In addition, the shock amount pattern information may include an inclination pattern form of a vehicle body in response to the detection value of the gyro sensor In addition, the shock amount pattern information may be provided in the form in which shock amount pattern forms are assigned according to the speeds of the vehicle, respectively. In addition, the pattern information may include sound pattern information. The sound pattern information is provided in a sound pattern form when the vehicle is in a normal state or an abnormal state. In addition, the sound pattern information may be provided in the form in which sound pattern forms are assigned according to the speeds of the vehicle, respectively. The memory 130 collectively refers to a non-volatile storage device configured to maintain stored information even when power is not supplied.

[0038] The control unit 140 may execute the client program stored in the memory 130, and apply the data received from the vehicle accident notification server 20, the data stored in the memory 130, and the data detected by the sensor module 110 to the program. The control unit 140 determines whether an accident has occurred in the vehicle through the data detected by the sensor module 110, and transmits corresponding accident data to the vehicle accident notification server 20 through the communication unit 120 when determining that the accident has occurred. The control unit 140 may control the client program to monitor the status and occurrence of the vehicle while being in a background executed state, so that accident data may be transmitted to the vehicle accident notification server 20 when the accident occurrence is detected.

[0039] The user interface 150 may include a display to display the state of the user terminal 10, the state of the client program and the like. In addition, the user interface 150 may include a touch panel, a keyboard and the like, so that the user may directly input data for manipulating the user terminal 10.

[0043] The accident detection unit 1410 detects the occurrence of accident by comparing the value detected by the sensor module 110 with the pattern information. Specifically, the accident detection unit 1410 may compare the value detected by the shock sensor module with the shock amount pattern information to determine that the accident has occurred when the matching degree is greater than or equal to a preset value. When the shock amount pattern information is assigned according to the speed of the vehicle, the accident detection unit 1410 may apply the speed of the vehicle detected through the position sensor module. In addition, the accident detection unit 1410 may be provided to receive the speed of the vehicle from a speedometer of the vehicle through the network and the communication unit 120, to apply the speed of the vehicle when comparing the value detected by the shock sensor module with the shock amount pattern information. In addition, the accident detection unit 1410 may additionally apply the degree of matching to the accident determination by comparing the sound stored through the recording unit 1400 with the sound pattern information.

[0044] The accident notification unit 1420 transmits the accident data to the vehicle accident notification server 20, when the accident detection unit 1410 determines that the accident has occurred. The accident data may include at least one of a current vehicle position detected by the position sensor at the time of transmitting the accident data, a value detected by the shock sensor module at the time when it is determined that the accident has occurred, and sound data recorded through the recording unit 1400 at the time when it is determined that the accident has occurred. When the accident detection unit 1410 detects that the accident has occurred, the accident notification unit 1420 may allow the accident data to be in a data transmission-standby state prior to transmitting the accident data, and transmit the accident data when a preset time elapses in the data transmission-standby state For example, the time for maintaining the transmission-standby state may be set as between 20 seconds and 40 seconds. In addition, the time for maintaining the transmission-standby state may be provided to be adjusted after the user executes the client program. In addition, during the data transmission-standby state, the user may set the accident data to be immediately transmitted through the interface, so that the accident data is transmitted before the preset time elapses in the data transmission-standby state. In addition, during the data transmission-standby state, the user may cancel the transmission of the accident data through the interface. The accident notification unit 1420, during the data transmission-standby state, may be set to display the execution status of the client program on the display, so as to enable the user to easily input the immediate transmission of the accident data or the cancellation of the accident data. In addition, the accident notification unit 1420 may simultaneously transmit data on whether the accident data is transmitted after the time for maintaining the transmission-standby state, or whether the accident data is transmitted by the user before the time for maintaining the transmission-standby state.

[0045] FIG. 4 is a block diagram showing a vehicle accident notification server of FIG. 1.

[0046] Referring to FIG. 4, the vehicle accident notification server 20 includes a communication module 210, a memory module 220 and a central processing unit 230. Components of the vehicle accident notification server 20 may be configured to be positioned in one physical space and directly connected to each other, or may be configured in the form of a system in which some of the components are positioned in different physical spaces and interconnected through a network.

[0047] The communication module 210 may be provided for wired and wireless data communication through the network to transmit and receive data with the user terminal 10. The communication module 210 may receive the accident data from the user terminal 10, and transmit the accident notification data to a server, terminal and the like of a related organization. The accident notification data refers to data that notifies the occurrence of the accident to insurance companies, emergency rescue agencies such as 911, vehicle towing companies, and other emergency contacts set by the user.

[0048] The memory module 220 may store received data, a program for providing a vehicle accident notification service, processing data generated by processing the received data, a program for performing an accident simulation and various other data.

In addition, the accident notification data provided to the insurance companies may include insurance information of the driver.

[0055] The pattern information generation unit 2340 may generate a pattern between accident data and an actual occurrence of an accident. In other words, the pattern information generation unit 2340 defines the accident data as an input factor and defines the output of the accident detection unit 1410 as an output factor, and then derives a correlation between the input factor and the output factor, thereby generating pattern information. The pattern information generation unit 2340 may be implemented through deep learning based on deep neural networks, so as to derive the correlation between the input factor and the output factor. In addition, the pattern information generation unit 2340 may update existing pattern information through new pattern information. In the pattern information generation unit 2340, the updated pattern information may be transmitted to the user terminal 10 when the pattern information is updated, so that the accident detection unit 1410 may detect whether the accident has occurred by using the updated pattern information.

[0056] The accident occurrence classification criterion generation unit 2350 may generate accident type classification criteria. In other words, the accident occurrence classification criterion generation unit 2350 defines the accident data as an input factor and defines the output of the accident type classification unit 2310 as an output factor, and then derives a correlation between the input factor and the output factor, thereby generating the accident type classification criteria.
