Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the drawings, the same reference numerals are used to designate the same or similar components throughout the drawings. In the following description of the present invention, a detailed description of known functions and configurations incorporated herein will be omitted when it may make the subject matter of the present invention rather unclear. In addition, the preferred embodiments of the present invention will be described below, but it is needless to say that the technical idea of the present invention is not limited thereto and can be variously modified by those skilled in the art.

The main function of eCall is to inform the center about the vehicle accident information, and this function is only possible when the modem operates normally. When the modem or antenna connection line is physically damaged, or the modem communication S / W error is not communicated to the center, the inter-vehicle communication communicates the accident information to the surrounding vehicles, and the neighboring vehicle receiving the accident information transmits its own eCall system It is an object of the present invention to provide an information communication and contact (indirect eCall function) on behalf of the center.

1 is a schematic block diagram of an eCall communication system according to an embodiment of the present invention.

The main communication between the eCall unit and the center (PSAP) uses the 2G / 3G communication network 130 through a modem in the eCall (a). Therefore, the eCall unit transmits the MSD message to the PSAP 140 when a vehicle accident occurs.

In the accident vehicle 110, the microcomputer in the eCall monitors the status of the modem. The monitoring contents check whether the signal is transmitted / received between the antenna and the modem and the modem module itself.

eCall When the microcomputer in my eCall checks the modem and antenna signals and the 2G / 3G communication network becomes unusable (bad modem, bad connection between modem and antenna (main and backup antenna), etc.) The mode is switched to use. At this time, the vehicles 120 around the accident vehicle 110 should also have the same V2V and eCall system (ⓑ, ⓒ).

2 is a reference diagram for explaining a method for determining whether a 2G / 3G network communication failure occurs in the eCall system.

Whether or not the 2G / 3G network communication can be performed in the eCall system can be determined by checking the state of the modem (Modem) 220 and the antenna signal to determine whether the network communication part is malfunctioning. Hereinafter, a method of determining a modem failure (malfunction) of the eCall system 200 will be described.

The normal operation of the modem 220 is monitored periodically (at regular time intervals) by the communication between the microcomputer 210 and the modem 220. The reason why the modem 220 does not operate properly is as follows.

First, modem hardware (parts, etc.) is bad.

Second, modem operation is poor due to error of modem module software and control software.

If the modem 220 fails to operate properly due to the two reasons described above, the microcomputer 210 can know the communication contents periodically with the modem 220.

Next, a failure determination method of the eCall system 200 using the antenna signal will be described.

Even if the modem 220 operates normally, even if the cable disconnection or the antenna signal between the antenna and the modem 220 is weak, it is regarded as a situation where the 2G / 3G network communication is broken and the modem is judged as a malfunction (malfunction).

The modem 220 informs the microcomputer 210 of the antenna signal and the signal value below the reference by communication so that the microcomputer 210 can recognize the antenna connection state and the 2G / 3G network communication is impossible.

3 is a flowchart showing a method for determining whether a 2G / 3G network communication failure exists in the eCall system.

The microcomputer constituting the eCall unit of the own car periodically communicates with the modem to monitor the modem status in real time (S310). At this time, if the communication is not established, the modem status can not be known and the modem control can not be performed. Therefore, the eCall unit of the own vehicle switches to the V2V communication mode (S330).

When the eCall system switched to the V2V communication use mode detects an accident or there is an emergency eCall button input, it transmits the information (location information, etc.) of the accident vehicle through the modem to the surrounding vehicles through V2V communication.

When the eCall unit of the vehicle is switched to the V2V use mode, when the vehicle accident is detected through the airbag operation signal or when the manual eCall button is pressed, the microcomputer transmits data contents (accident vehicle information) And transmits to H / U through CAN.

The information sent to the MM-CAN is the vehicle information and the unique modem information of the vehicle. The reason why the vehicle-specific modem information is sent to the eCall unit of the other vehicle via V2V is that the eCall unit of the other vehicle receives the information of the accident vehicle instead of the own information and informs it to the center instead. This is to help the PSAP know if the accident happened.

The H / U in the accident vehicle receives the information from the eCall unit and transmits it to the surrounding vehicles by V2V communication (wave communication).

If it is determined that the antenna signal is disconnected or the state of the 2G / 3G communication network is equal to or lower than the communication possible level (S340), the eCall unit of the own vehicle switches to the V2V communication mode (S330).

If it is determined that the antenna signal is not disconnected and the state of the 2G / 3G communication network exceeds the communication possible level (S340), the eCall unit of the own vehicle switches to the modem communication mode (S350).

4 is a reference diagram for explaining a method for determining which vehicle in the vicinity of an accident vehicle should give priority to an emergency signal when an eCall is returned from a nearby vehicle.

When the neighboring vehicles 420 and 430 capable of indirect eCall communication respond to the accident vehicle 410 at V2V, the response data includes the state information of the neighboring vehicles capable of indirect eCall communication and responds. That is, the response data includes the current traveling speed of the vehicle and the modem status information of the vehicle.

Then, the accident vehicle 410 delivers the emergency signal to the vehicle 430 having the slowest vehicle movement speed among the response data of the indirect eCall-able nearby vehicles 420 and 430. [

When the neighboring vehicles 420 and 430 pass through the accident vehicle 410, since the reply to the eCall indirect communication function can be performed in an area less deviated from the accident location, To deliver emergency signals.

Reference numeral 440 denotes a process in which the accident vehicle 410 transmits an indirect eCall communication to the neighboring vehicles 420 and 430. And reference numeral 450 denotes a process in which the neighboring vehicle B 430 returns the indirect eCall to the accident vehicle 410. And reference numeral 460 denotes a process in which the neighboring vehicle A 420 returns the indirect eCall to the accident vehicle 410. And reference numeral 470 denotes a process in which the accident vehicle 410 transmits the emergency signal to the neighboring vehicle B 430 according to the priority order. In this case, the vehicle whose vehicle speed is relatively slow is given priority. In FIG. 4, since the neighboring vehicle B 430 is slower than the neighboring vehicle A 420 by 20 km / h, the neighboring vehicle B 430 is given priority.

When the modem status is in a failure state or the antenna signal is at a communication-enabled level or lower among the data coming from the neighboring vehicles 420 and 430, it is excluded from the nearby vehicles to which the emergency signal is transmitted, irrespective of the priority according to the vehicle speed.

FIG. 5 is a flowchart illustrating a method for determining a priority of an emergency signal to a vehicle around an accident vehicle reference when eCall is returned from a nearby vehicle.

Referring to FIG. 5, when the response data is received from nearby vehicles (S510), the accident vehicle determines whether the modem state of the nearby vehicle is normal based on the modem state information included in the response data (S520).

If it is determined that the modem status of the nearby vehicle is abnormal, the vehicle speed information of the nearby vehicle whose modem status is abnormal is discarded (S530).

Thereafter, the accident vehicle temporarily stores vehicle speed information of nearby vehicles whose modem status is normal (S540).

In step S550, the accident vehicle compares the vehicle speed information of the nearby vehicles and determines a vehicle having a higher priority (e.g., giving priority to a relatively slower vehicle).

Thereafter, the accident vehicle transmits an emergency signal to the vehicle having the highest priority (S560).

6 is a detailed configuration diagram of an eCall communication system according to an embodiment of the present invention.

The first H / U 610 is H / U provided in the other vehicle, and the second H / U 620 is H / U provided in the own vehicle. The eCall unit 650 and the H / U 620 of the vehicle send and receive data to / from the M / M-CAN (Multimedia CAN). The eCall unit 650 of the vehicle displays an eCall status, an update, etc. on the H / U monitor.

The airbag control unit (ACU) 630 outputs an A / Bag Sig. (A signal indicating that the airbag has been activated) to the eCall unit 650 while the airbag operates in the event of a vehicle collision. The eCall unit 650 recognizes that a vehicle collision accident has occurred with this signal, and informs the center (PSAP) of the accident of the vehicle via the modem 655. [ The airbag signal is output directly to the eCall unit 650 and also informs the airbag that it is operating via the C-CAN (chassis CAN) (dual complementary signaling).

The MICOM 652 determines whether an accident has occurred in the vehicle. The MICOM 652 receives sensor information of the vehicle, and controls the operations of the GNSS module 656 and the modem 655, the microphone 641 and the amplifier 651, and the like.

The BUB (Back Up Battery) 654 is a built-in battery for use as a backup power source of the eCall unit 650 in a situation where the power source unit 653 of the eCall unit 650 can not play a normal role.

The modem 655 notifies the center (PSAP) of a vehicle accident through the 2G / 3G communication network and allows the center to make an emergency call. When the network signal from the main shark antenna 662 is not detected, the connection between the modem and the antenna is switched to the 2G / 3G back up antenna 661 by the Main Shark antenna 662, Even if the antenna 662 is broken or broken, an emergency signal is sent so that it has a double complementary structure.

The microphone 641, the amplifier 651, the speaker 642, and the like are voice communication devices for an emergency call with the center (PSAP) after a vehicle accident.

The H / U 610 of the nearby vehicle recognizes that the content received by the V2V communication is the contents of the eCall of the accident vehicle, and sends the eCall information of the accident vehicle to the eCall unit through the MM-CAN.

Then, the H / U 610 of the nearby vehicle sends the eCall information of the received accident vehicle to the eCall unit, and the eCall unit notifies the eCall information of the accident vehicle and the modem specific information to the center through its modem.

The center recognizes that eCall information has been sent instead of an accident vehicle, and returns the eCall information to the surrounding vehicles.

When the neighboring vehicle receives the center reception reply information, if it is around the accident vehicle, it informs the accident car through the V2V communication that the eCall center has been accepted.

FIG. 7 is a reference diagram for explaining a method of returning an eCall system in the event of a vehicle collision due to a chain collision. FIG.

When an indirect eCall request is received from the failed vehicle C (730) when all surrounding vehicles 710, 720, 730 are driving their eCall system in an accident due to a chain collision, The vehicle A 710 having a relatively small distance to the vehicle C 730 among the vehicle 710 and the vehicle B 720 distinguishes communication with the center 750 and proceeds the process. In other words, the vehicle A 710 carries on its own eCall process and on the other hand the indirect eCall process of the vehicle whose modem fails. At this time, the vehicle A (710) can proceed to its own eCall process first and the indirect eCall process of the vehicle whose modem has failed.

When it is determined that the vehicle C 730 has reported accident information from the center 750, the vehicle A 710 returns to the vehicle C 730 that the indirect eCall is normally reported.

FIG. 8 is a flowchart illustrating an eCall process according to an embodiment of the present invention.

When the startup is ON, the eCall unit inputs vehicle information and GPS information (S805).

Thereafter, the eCall unit determines whether the modem is operating normally and whether the antenna signal is normal (S810).

If it is determined that the modem is operating normally and the antenna signal is normal, the eCall unit switches to the modem communication mode (S815). On the other hand, if it is determined that the modem is not operating normally or the antenna signal is not normal, the eCall unit switches to the V2V communication mode (S820).

Then, the eCall unit determines whether the airbag operation signal is input (S825).

If it is determined that the airbag operation signal is not input, the eCall unit determines whether the eCall emergency button is input (S830). If it is determined that the eCall emergency button is not inputted, the eCall unit performs the process from step S805 again.

If it is determined that the airbag operation signal is input or the eCall emergency button is input, it is determined whether the eCall unit is in the modem communication mode (S835).

If it is determined that the mode is the modem communication mode, the eCall unit informs the center of the accident information through the modem communication mode (S840). On the other hand, if it is determined that the mode is not the modem communication mode, the eCall unit causes the neighboring vehicles to inform the center of the accident information through the V2V communication mode (S845, S850).

9 is a flowchart illustrating a process of an indirect eCall process of a vehicle in which the eCall unit according to an exemplary embodiment of the present invention has failed.

If indirect indirect eCall is requested from V2V communication (S910), the eCall unit receives the vehicle information of the failed vehicle (S920).

Then, the eCall unit receives the eCall information of the vehicle whose modem has failed to the center through the modem communication mode (S930).

When the eCall unit receives a reply from the center that the eCall information of the failed vehicle has been received (S940), the eCall unit returns the indirect eCall completion to the vehicle whose modem has failed through the V2V communication mode (S950).

The eCall unit replies to the indirect eCall completion by repeating it 5 times in case there is no communication ACK from the vehicle where the modem fails, and then ends the indirect eCall process.
