Hereinafter, the working principle and embodiments of the present invention will be described with reference to the accompanying drawings.

Referring to FIG. 1, the e-Call system receives a vehicle 1 and accident information from the vehicle 1, then an insurance company 20, a police station 30, a fire station 40 or a towing company necessary for accident handling. (50) and the like to include a service center (10).

The e-Call system enables the insurance company (20), police station (30), fire station (40), or towing company (50) to quickly take necessary emergency measures according to the scale of damage and the degree of injury in the event of a traffic accident. So that the service center 10 can recognize the traffic accident through the data received from the vehicle 1, and the service center 10 re-produces the location of the accident, the degree of injury to the victim, and information necessary for emergency rescue. It means a comprehensive traffic management system that connects related organizations.

Specifically, key elements for operating the e-Call system are the vehicle 1, the service center 10, and communication connecting the service center 10 and the vehicle 1 must be defined. To this end, the vehicle 1 according to the disclosed embodiment includes the ITS module 100 based on P-ITS-S defined in the ISO standard. A specific method for the ITS module 100 to transmit a service request signal to the service center 10 according to a driver's input command will be described later through other drawings.

Meanwhile, the ITS module 100 may collect data on various types of traffic information collected by the vehicle 1 and reconstruct them in a form desired by the driver. To this end, the ITS module 100 implements a database function for storing data collected from various sensors and an electronic control device (see FIG. 2) of the vehicle 1 and a program for producing the data stored in the database into necessary signals or traffic information. has been In addition, the ITS module 100 includes a communication interface that performs external base stations (V2I communication) of the vehicle 1, other vehicles (V2V communication), pedestrians (V2P communication), and vehicle networks (V2N communication). .

In the disclosed embodiment, the ITS module 100 is a component of the ITS Station presented in the ISO (TC 204) standard document (17465-1). Here, the ITS Station improves the safety, continuity, efficiency and convenience of road traffic through two-way communication and mutual sharing of traffic information between vehicles, road infrastructure (Roadside), service centers or traffic centers (Central) and pedestrians (Personal). means an open platform system for the purpose of improving The ITS Station is provided as a reference architecture constituting from the first layer of the communication area to the seventh layer of the application expressed as a service, and the ITS module 100 of the vehicle 1 conforms to the communication protocol of the ITS Station architecture. Therefore, in order to receive support for manpower or accident treatment vehicles necessary for accident handling shown in FIG. 1, the ITS module 100 transmits a service request signal to the service center 10 according to the C-ITS communication protocol. For example, the ITS module 100 transmits a service request signal to a portable terminal through the driver's WiFi or Bluetooth so that a service request signal necessary for handling an accident can be transmitted to the service center 10, or the vehicle 1 A service request signal may be transmitted to a nearby Road-Side Equipment (RSE).

When the service center 10 receives the service request signal transmitted by the ITS module 100, the service center 10 provides the insurance company 20, the police station 30, and the fire station ( 40) or a towing company (50).

When an accident occurs in the vehicle 1 according to an embodiment, an electronic control unit (ECU) collects and processes various sensor data. The electronic control unit performs various operations for the operation of the vehicle 1, the driver's safety and autonomous driving, and various electronic control devices may be provided in the vehicle 1. However, in FIG. 2 , the airbag management unit 110 that operates when an accident occurs and the system that operates when a vehicle overturns or suddenly stops, that is, the accident management unit 120 is described as an example of an electronic control device.

Specifically, the airbag manager 110 may include a G sensor 111, an ECU 112, and a Supplemental Restraint System (SRS) 113.

The G sensor 111 may include an acceleration sensor and a gyro sensor. However, the airbag management unit 110 mainly uses sensor data of the acceleration sensor, but may determine whether the airbag is operating by combining sensor data of the gyro sensor and sensor data of the acceleration sensor.

The SRS 113 is a component that controls the inflation rate of an operating airbag, and the disclosed SRS 113 can adjust the inflation of the airbag by scanning occupants, such as the driver's position in the vehicle 1 and the presence or absence of a seat belt. To this end, the SRS 113 is controlled by the ECU 112 included in the airbag management unit 110 and adjusts the inflation speed of the airbag.

The ECU 112 may control the overall airbag management unit 110 and simultaneously perform vehicle network communication with other electronic control units of the vehicle 1 . In particular, the ECU 112 of the airbag management unit 110 may perform vehicle network communication with the ITS module 100 .

For example, due to a contact accident of the vehicle 1, the G sensor 111 transmits sensor data to the ECU 112. The ECU 112 determines whether to operate the airbag and operates the SRS 113. Also, the ECU 112 generates a DX message to the ITS module 100 based on the sensor data. The DX message may include various data such as types and values of trigger data and sensor data to be included in transmission from the ITS module 100 to the service center 10 according to the protocol of the ITS Station. The DX message may be transmitted to the ITS module 100 through CAN communication or Ethernet communication or the driver's mobile.

The accident management unit 120 detects overturning or rapid deceleration of the vehicle 1 and then performs various vehicle controls to minimize accidents. For example, the accident management unit 120 may perform body posture control (ESP). If the driver turns the steering wheel sharply left or right, the car may skid or roll over. Therefore, the accident management unit 120 measures the movement of the car at preset intervals. Specifically, the accident management unit 120 may compare the rotation speed of the wheels with the actual driving speed of the vehicle 1 collected through the G-sensor 121 . Also, when the vehicle 1 slips, the accident management unit 120 may collect the slipping direction through the gyro sensor 123 . Based on the sensor data collected through the G sensor 121 and the gyro sensor 123, the accident management unit 120 may prevent an accident by adjusting the locking of the brake.

Even if the accident management unit 120 performs vehicle posture control, an accident may occur. When an accident of the vehicle 1 while driving occurs, sensor data collected by the accident management unit 120 from the G-sensor 121 undergoes a rapid change. The ECU 122 of the accident management unit 120 may determine that an accident has occurred based on the data of the G sensor 121 . ECU 122 may generate a DX message based on the above-described determination. At this time, the ECU 122 may insert data about the direction in which the vehicle 1 was overturned based on the sensor data of the gyro sensor 123 into the DX message.

When the airbag management unit 110 or the accident management unit 120 transmits the generated DX message to the ITS module 100, the ITS module 100 generates a service request signal requesting an accident handling service to the service center 10. . A specific method for the ITS module 100 to perform the incident handling service will be described later through other drawings.

The ITS module 100 uses a memory for storing data for an algorithm or a program that reproduces the algorithm for performing the method for notifying an accident of the vehicle 1 according to the disclosed embodiment, and the data stored in the memory. It may be implemented as a processor that performs the above-described operation. In this case, the memory and the processor may be implemented as separate chips. Alternatively, the memory and the processor may be implemented as a single chip.

In particular, the memory includes non-volatile memory devices such as cache, read only memory (ROM), programmable ROM (PROM), erasable programmable ROM (EPROM), electrically erasable programmable ROM (EEPROM), and flash memory, or random RAM (RAM). It may be implemented as at least one of a volatile memory device such as an access memory), a hard disk drive (HDD), or a storage medium such as a CD-ROM, but is not limited thereto.

Before generating a service request signal to the service center 10, the ITS module 100 confirms a service request on a display (head unit) included in the vehicle 1 or a user terminal of a driver or selects a vehicle for handling an accident. A user interface that induces can be output.

The ITS module 100 may include at least one of a short-distance communication interface, a wired communication interface, and a wireless communication interface in order to communicate with the

electronic control units

112 and 112 of the vehicle 1 and the service center 10. .

The short-distance communication interface uses a wireless communication network such as a Bluetooth module, an infrared communication module, a Radio Frequency Identification (RFID) communication module, a Wireless Local Access Network (WLAN) communication module, an NFC communication module, and a Zigbee communication module to transmit signals at a short distance. It may include various short-range communication modules that transmit and receive.

The wired communication interface includes a controller area network (CAN) communication module, a local area network (LAN) module, a wide area network (WAN) module, or a value added network (VAN) module. USB (Universal Serial Bus), HDMI (High Definition Multimedia Interface), DVI (Digital Visual Interface), RS-232 (recommended standard 232), power line communication, or POTS (plain old telephone service), etc. It may include various cable communication modules.

In addition to the Wi-Fi module and the Wi-Bro module, wireless communication interfaces include GSM (global System for Mobile Communication), CDMA (Code Division Multiple Access), WCDMA (Wideband Code Division Multiple Access), UMTS (universal mobile telecommunications system) ), a wireless communication module supporting various wireless communication schemes such as Time Division Multiple Access (TDMA) and Long Term Evolution (LTE).

The service center 10 may be divided into an emergency service center 11 and a car incident notification service center 12 .

The emergency service center 11 calls an ambulance and dispatches an ambulance based on vehicle location information included in the service request signal transmitted by the ITS module 100 .

The accident notification service center 12 handles accident handling services such as accident reception, police car dispatch, tow truck dispatch, accident handling vehicle dispatch, or insurance vehicle dispatch based on the service request signal transmitted from the ITS module 100 . In addition, the accident notification service center 12 may transmit monitoring information about the location and expected arrival time of the dispatched accident handling vehicle, retrieve the accident notification history of the vehicle 1, and provide the information to the vehicle 1. Various accident handling services performed by the emergency service center 11 and the accident notification service center 12 will be described later through other drawings.

Meanwhile, in the disclosed embodiment, the emergency service center 11 may dispatch an ambulance, and the accident notification service center 12 dispatches an insurance vehicle, a police car, and a towing vehicle to the scene of an accident. In addition, the accident notification service center 12 transmits monitoring information including location information of an ambulance dispatched by the emergency service center 11 on behalf of the emergency service center 11 . This embodiment varies depending on where the ITS module 100 transmits the service request signal. That is, the disclosed ITS module 100 may determine which service center to transmit the service request signal to, and the ITS module 100 transmits the service request signal to the emergency service center 11 or the accident notification service center 12. A specific method will be described later through other drawings below.

Specifically, the driver 2 needs to log in 101 to the ITS Station (hereinafter referred to as P-ITS-S) in order to request a service and proceed with an accident handling service to the service center 10 . Specifically, the driver turns on the P-ITS-S through various input buttons of the vehicle 1 or a touch input to the display.

When VIN-S (Vehicle Identification Number-System) software is activated by turning on the P-ITS-S, the ITS module 100 outputs a log-in screen of the VIN-S software through the display. The driver 2 inputs his or her ID and password. After the ITS module 100 transmits the log-in information through the communication network, it checks whether authentication has been performed. If authentication is confirmed, the ITS module 100 accesses the ITS-S gateway through the VIN-S software, and outputs a screen indicating that log-in has been successfully performed on the display.

After log-in is completed, the driver 2 may request dispatch of an ambulance according to an embodiment (111). Specifically, the ITS module 100 clicks a button (or user interface) labeled "Call an ambulance" through the display.

When the ambulance dispatch input of the driver 2 is received, the ITS module 100 determines a service center for ambulance dispatch based on the accident handling service and vehicle location information. Here, the accident handling service will be "ambulance dispatch" input by the driver 2, and the location information of the vehicle 1 is collected through another electronic control unit of the vehicle 1 or a GPS signal receiver (not shown). In the disclosed embodiment, the ITS module 100 requests a service request signal including an ambulance request (hereinafter referred to as a first service request signal) to the emergency service center 11 for the accident handling service of ambulance dispatch, and at the same time the accident notification service center 12 ) also transmits the first service request signal.

The first agent (Accident Data Evaluation Agent in P-ITS-S, 3) of the emergency service center 11 is based on the DX message included in the first service request signal, accident type, accident-related data, and location information of the vehicle. to receive and analyze accidents. At the same time, the first agent 3 allocates an ambulance that can be dispatched based on the location information of the vehicle 1 and then dispatches the ambulance.

In addition, based on the first service request signal transmitted to the accident notification service center 12, the second agent (Emergency Center Agent 4) of the accident notification service center 12 determines whether an ambulance is dispatched from the emergency service center 11. receive Then, the second agent 4 responds to the monitoring information request signal (hereinafter referred to as the second service request signal) of the ITS module 100 . That is, the second agent 4 may provide the driver 2 with information about the current location of the ambulance dispatched by the emergency service center 11 and the expected arrival time to the accident point.

According to another embodiment, the accident notification service center 12 receives an accident notification (121), dispatches an accident handling vehicle (police car, tow truck, insurance vehicle, etc.) (122), and transmits monitoring information of the dispatched accident handling vehicle (123). And an accident handling service including an accident notification history 124 may be performed. This accident processing service is processed through a first service request signal, a second service request signal, or a third service request signal transmitted from the ITS module 100 to the accident notification service center 12 .

In detail, the accident notification reception 121 is processed through the first service request signal transmitted by the ITS module 100 . If the driver 2 clicks the user interface related to the Vehicle Incident Notification output by the ITS module 100, the ITS module 100 outputs a user interface leading to input of the accident type and accident-related data. . When the driver 2 inputs the accident type and accident-related data, the ITS module 100 determines the service center 10 to which the first service request signal including the input accident type and accident-related data will be transmitted. For example, when the driver 2 inputs data on vehicle damage and damage degree as accident-related data, the ITS module 100 sends a first service request signal to the service center 10, An accident notification service center 12 other than the service center 11 is determined. The ITS module 100 transmits the first service request signal including the DX message, accident type, accident-related data, and location information of the vehicle 1 to the accident notification service center 12 . After transmitting the approval signal of the first service request signal to the ITS module 100, the second agent 4 may determine dispatch of a towing vehicle according to the degree of damage along with the insurance vehicle.

If the information of the first service request signal is not sufficient, the second agent 4 transmits a signal indicating that the service request data is not valid to the ITS module 100, and the ITS module 100 returns to the driver 2. After outputting a user interface for prompting the input of accident types and accident-related data, the above-described process is repeated.

Regarding an example of dispatching an accident repair vehicle 122 , the second agent 4 determines dispatch of an accident repair vehicle based on the first service request signal transmitted by the ITS module 100 . The ITS module 100 may output a user interface for prompting the driver 2 to input the type of accident repair vehicle based on the approval signal transmitted by the second agent 4 . If the driver 2 inputs 'police car' as an accident handling vehicle, the ITS module 100 transmits a first service request signal requesting dispatch of a police car to the accident notification service center 12 again, and the second agent (4) may request the dispatch of police cars to the police station.

Meanwhile, the disclosed ITS module 100 transmits the first service request signal and transmits monitoring information of an accident repair vehicle to be dispatched by the emergency service center 11 or the accident notification service center 12 without input from the driver 2. A second service request signal requested 123 is generated. That is, the ITS module 100 monitors the vehicle to be dispatched without waiting for the second agent 4 to respond to the dispatch request after transmitting the first service request signal for dispatching the police car to the accident notification service center 12. A second service request signal requesting information is generated.

Even if the second agent 4 forgets to transmit the monitoring information of the police car dispatched, the ITS module 100 can transmit the second service request signal to the accident notification service center 12 without input from the driver 2. there is. Based on the second service request signal, the second agent 4 transmits monitoring information to the ITS module 100, and the driver 2 can acquire information such as an expected arrival time of the accident repair vehicle.

In relation to the accident notification history 124 , after transmitting the first service request signal and the second service request signal, the ITS module 100 may output a user interface related to the accident notification history request.

If the driver 2 performs an input related to the accident notification history request, the ITS module 100 generates a third service request signal requesting information on the accident notification history to the accident notification service center 12, and sends it to the accident notification service center 12. It is transmitted to the accident notification service center 12. After the second agent 4 transmits information related to the accident notification history to the ITS module 100 , the ITS module 100 outputs the received accident notification history to the driver 2 .

Regarding the log-out 102, the ITS module 100 outputs a user interface related to log-out through the display while the VIN-S software is activated in the driver 2. If the driver 2 inputs log-out, the ITS module 100 terminates the connection with the vehicle ITS-S gateway. After the connection is terminated, the ITS module 100 may output a user interface indicating whether or not the connection is terminated through CAN-S software.

Through this, the driver 2 can request prompt accident notification, dispatch of an ambulance or accident handling vehicle, information on accident notification history, etc. to the service center 10 through a simple input command to the ITS module 100, and accident handling. Vehicle monitoring information may be provided without specific input.

The ITS module 100 receives a DX message from another electronic control device of the vehicle 1 (200).

The DX message may include sensor data collected by the electronic control unit by various sensors and data related to an operation controlled by the electronic control unit. The DX message may be transmitted to the ITS module 100 through the vehicle network, but if the vehicle network is unable to communicate due to an accident, it may also be transmitted to the ITS module 100 through the driver's user terminal or wireless communication.

The ITS module 100 outputs a user interface for inducing selection of an accident handling service to the driver (210).

Here, the accident handling service includes at least one of an accident notification, a request for a police car, a request for an ambulance, a request for a tow truck, and a request for an insurance vehicle. The ITS module 100 may induce a driver's selection by outputting an icon or a graphic interface displaying the type of the above-described accident handling service through a display screen.

The ITS module 100 receives input from the driver (220).

If no input is received (No in 220), the ITS module 100 stands by with a screen continuously displaying a user interface leading to selection of an accident handling service.

If the input is received (Yes in 220), the ITS module 100 determines the service center 10 related to the incident handling service and generates a first service request signal (230).

The ITS module 100 determines a service center to which a first service request signal is to be sent according to various types of accident handling services. If the driver selects an ambulance request, the ITS module 100 sends the first service request signal to the service center 10, the emergency service center 11 and the accident notification service center 12. The first service is sent to two service centers. A request signal can be transmitted. If the driver selects at least one of accident notification, police vehicle request, tow truck request, or insurance vehicle request as the accident handling service, the ITS module 100 determines transmission of the first service request signal to the accident notification service center 12. can

The ITS module 100 may determine the service center 10 based on the current location of the vehicle 1 . For example, when multiple accident notification service centers 12 are operated by region, the ITS module 100 determines to transmit a first service request signal to the accident notification service center 12 close to the location of the vehicle 1. can

When the service center 10 is determined, the ITS module 100 transmits a first service request signal to the determined service center 10 (240).

The ITS module 100 receives an acceptance signal, that is, a response signal from the service center 10 based on the first service request signal (250).

If the reception signal is not received (No in 250), the ITS module 100 transmits the first service request signal to the service center 10 again while notifying failure of the accident notification.

If the acceptance signal is received, the ITS module 100 generates a second service request signal requesting monitoring information while outputting a user interface related to acceptance completion on the display, and sends the second service to the accident notification service center 12. A request signal is transmitted (260).

Here, the monitoring information includes information about the location of the dispatched vehicle and the expected arrival time of the vehicle 1 to the accident point. The monitoring information is transmitted by the accident notification service center 12 according to the second service request signal, and the monitoring information according to ambulance dispatch is also transmitted by the accident notification service center 12, not the emergency service center 11. Accordingly, the ITS module 100 requests the second service request signal requesting ambulance monitoring information to the accident notification service center 12 instead of the emergency service center 11 .

Meanwhile, when receiving the reception signal of the first service request signal, the ITS module 100 generates a second service request signal to request monitoring information of the dispatched vehicle. Accordingly, the driver does not have to request monitoring information of the dispatched vehicle related to the accident handling service again, and can quickly monitor the location of the dispatched vehicle after an accident.

The ITS module 100 receives monitoring information from the accident notification service center 12 (270), and the ITS module 100 receives an input from a driver through a user interface for outputting monitoring information (280).

Based on the second service request signal, the ITS module 100 receives monitoring information, but the ITS module 100 does not output monitoring information without a driver's input.

The ITS module 100 generates a second service request signal requesting ambulance monitoring information without a driver's input. That is, the disclosed ITS module 100 generates a second service request signal so that the driver can immediately know the current location and expected arrival time of the ambulance when requested by the driver.

The generated second service request signal is transmitted to the accident notification service center 12 , and the accident notification service center 12 transmits monitoring information of the dispatched ambulance to the ITS module 100 .

The ITS module 100 receives an input requesting monitoring information from a driver (440).

If there is no user input (No in 440), the ITS module 100 does not output monitoring information based on the second service request signal (end).

If there is a user's input (Yes in 440), the ITS module 100 outputs a user interface related to monitoring information through a display (450).

The ITS module 100 transmits a first service request signal (500).

The first service request signal is transmitted to the service center determined by the ITS module 100 . If the driver selects the user interface for requesting the towing vehicle, the ITS module 100 transmits a first service request signal to the accident notification service center 12 .

The ITS module 100 outputs a user interface related to the accident notification history request (510).

If there is no driver's input (No in 520), the ITS module 100 waits to receive another input command (end).

If there is a driver's input (Yes in 520), the ITS module 100 generates a third service request signal (530).

Here, the third service request signal is a request signal for an accident notification service as a destination. in other words. Unlike the second service request signal, the third service request signal is generated by a driver's input.

The ITS module 100 transmits the third service request signal to the accident notification service center 12 (540).

The accident notification service center 12 transmits information about the accident notification history of the vehicle 1 and other accident notification history of the driver to the ITS module 100 based on the third service request signal.

The ITS module 100 receives (550) history information.

If history information is not received (No in 550), the ITS module 100 transmits a third service request signal to the accident notification service center 12 again. Here, the ITS module 100 transmits the third service request signal according to preset intervals.

If history information is received (Yes in 550), the ITS module 100 outputs the history information (560).

8 is a flowchart of a log-out access method according to an embodiment.

The ITS module 100 outputs a user interface associated with the CAN-S software and a log-out user interface (600).

Here, the CAN-S software is defined in ISO 11898, and is software necessary for the ITS module 100 to connect to the network of the vehicle 1. The driver may transmit an input command for log-out to the log-out user interface.
