The server 400 of the accident recovery institution is an external server that is not included in the present invention, and may be an external server held by organizations for responding to vehicle accidents.

For example, a safety report center or an emergency medical hospital may become an accident handling institution, and if necessary, an insurance company may be included as an accident handling institution.

Accordingly, the condition for the server 100 to select the server 400 of the accident recovery agency may vary depending on the type of accident recovery request.

For example, if the damage to the vehicle is minor and the occupant is not injured, the server 400 of the accident recovery agency can be used only by the insurance company, and if the vehicle is damaged and the occupant is injured, the server of the emergency rescue agency may be used. It can be.

In an optional embodiment, the accident response request received by the server 400 of the accident recovery institution may further include vehicle location information, and based on this, it is possible to quickly dispatch personnel to the point where the accident occurred.

Meanwhile, the communication network serves to connect each device including the server 100.

The database 140 may store information on an occupant using a vehicle.

For example, when medical information about an occupant is stored and a request for accident handling occurs, it is transmitted to the server 400 of the accident handling institution together.

Through this, the server 400 of the accident recovery institution can quickly proceed with medical work corresponding to the occupant's medical information, thereby preventing secondary damage that may occur after the accident.

If medical information on the occupant is stored in the database 140, this is pre-stored in the server 100 by the user from the user terminal 300.

In another embodiment, the database 140 may be omitted from the server 100, and information of the occupant may be stored and used in a database included in the accident detection device 200 or the user terminal 300.

Although not shown in FIG. 2, some of the passenger's information may be stored in a database (not shown) that is physically or conceptually separated from the database 140.

Representative functions provided as an interface of the user operation panel may be a safety check function and an emergency help function, as described above.

First, in the safety check function, the server 100 detects the second sensing signal and recognizes that the vehicle is in an accident, but when there is no actual accident or when an accident occurs but the driver is not greatly injured or in a minor state, A safety signal may be generated and transmitted to the server 100.

Conversely, the emergency help function is a button for forcibly performing an accident recovery request when an emergency situation occurs and assistance is not generated due to a sensor failure, or when a request for assistance is not made due to a sensor failure. Can be used as

4 is a flowchart illustrating a process of detecting an accident in real time and automatically propagating an accident according to an embodiment of the present invention.

* Referring to FIG. 4, the server 100 recognizes that the accident detection device 200 is operated (S310).

The server 100 recognizes that the user is boarding the vehicle through the driving signal received in step S310, and when the driving signal ends, the server 100 recognizes that the user has got off the vehicle.

Next, the server 100 receives a first sensing signal from the accident detection device 200 (S320).

At this time, in general, in order to drive the vehicle, it is necessary to always step on the accelerator pedal and the brake pedal provided in the vehicle. However, when the driver recognizes an urgent situation, he or she presses the pedal at a stronger or faster speed than usual in order to escape the crisis.

The accident detection device 200 detects a situation in which the user steps on the pedal, determines as a precursor of an accident, generates a first sensing signal capable of giving a warning to the user, and transmits the first sensing signal to the server 100.

At this time, since the first sensing signal is installed in the accelerator pedal and brake pedal, which are essentially used to drive the vehicle, it does not operate when the pedal is stepped at a normal speed or pressure, and the sensor is only stepped on at a preset speed or pressure May be recognized to generate a first sensing signal.

As a further embodiment, a function of adjusting a preset speed or pressure for generating the first sensing signal to suit the driver's tendency may be previously provided to the driver.

As another additional embodiment, the first sensing signal may be generated even according to a sudden change in the vehicle speed.

In an optional embodiment, when the first sensing signal is received in step S320, the accident attention signal may be directly transmitted to the accident detection device 200 or the user terminal 300 at the same time.

After the step (S320), the server 100 receives the second sensing signal within a preset time period (S330) depending on whether or not the subsequent progress is changed.

If the second sensing signal is not transmitted within a preset time, the server 100 transmits an accident warning signal to the user terminal 300 to complete the step (S340).

This may determine that an accident did not occur because the driver did not receive a separate shock from the vehicle after the first sensing signal by safely coping with the situation that occurred while the vehicle was driving.

However, if the first sensing signal is caused by the driver's carelessness or the habit of violently stepping on the accelerator or brake, the server 100 or the accident detection device 200 or the user terminal 300 warns of an accident. A signal is generated and notified to the user.

In a further embodiment, the accident warning signal provided to the driver may be transmitted to a driver of a vehicle running near a vehicle in which the corresponding driver is boarded to propagate the risk of an accident.

In addition, after step S340, the server 100 may store a driving area of the vehicle in which the first sensing signal is generated.

Thereafter, when a vehicle enters a driving area in which the first sensing signal is generated more than a preset number of times, the server 100 determines that the driving area is a place with a high probability of an accident, generates an accident warning signal, and a preset user terminal ( 300).

At this time, the operating area may be, for example, an accident-prone area, a child protection area, or an area where wild animals appear frequently.

In addition, the driver analyzes the pattern of rapid acceleration or deceleration in a specific area, calculates the cause of the pattern being performed in a specific area, and transmits an accident warning signal to the driver in advance to perform accident prevention.

In addition, the analyzed pattern may be stored in the server 100 and shared with other drivers. Therefore, when another driver is in a situation corresponding to the pattern, an accident warning signal may be transmitted.

If, after step S330, the server 100 receives the second sensing signal within a preset time, the server 100 recognizes that an accident has occurred in the vehicle (S341).

In this case, the accuracy of determining whether an accident has occurred based on the numerical information of at least one of the speed or pressure applied to the pedal sensor included in the first sensing signal and the operation state of the vehicle before and after receiving the second sensing signal can be improved. have.

In addition, the vehicle speed is calculated based on the numerical information of at least one of the speed or pressure applied to the pedal sensor, and the amount of impact applied to the vehicle and the vehicle speed when an accident calculated based on the second sensing signal occurs. You can also judge the scale of

In other words, it is possible to predict how much damage has been inflicted on the vehicle by combining the speed at the time of the accident and the amount of impact the vehicle receives due to the accident. In addition, as a further embodiment, when a plurality of impact sensors are provided at various locations of the vehicle, it is possible to predict which part of the vehicle is intensively damaged by combining the amount of impact received at the location where the impact sensor operates.

In addition, in an optional embodiment, even when the first sensing signal is not received and the second sensing signal is received, it is possible to recognize an accident situation. This is because accidents may not be caused by the user's inexperience or careless driving, but may also be caused by the vehicle of another person or external factors.

In addition, in order to arbitrarily stop the request for accident handling after the occurrence of the second sensing signal, the accident detection device 200 may be manipulated to generate a safety signal and then transmit it to the server 100.

This may be a task that is performed when the shock sensor malfunctions and generates a second sensing signal, or it is determined that the user can correct an accident that has occurred, and thus does not want to receive a request for correcting the accident.

Finally, the server 100 requests the accident recovery from the server 400 of the accident recovery institution (S342).

In an optional embodiment, by ignoring all of the above-described steps and manipulating the emergency help button provided in the accident detection device 200, the user may arbitrarily request accident recovery.

In addition, as a further embodiment, the server 100 receives an accident occurrence or emergency rescue request signal recognized by the accident detection device 200 and the user terminal 300, and notifies it to the server 400 of the accident handling institution. It can only play the role of. That is, the processes from steps S310 to S340, which are disclosed in the operation flow diagram of FIG. 4, can be performed only by the accident detection apparatus 200. At this time, the server 100 is capable of promptly notifying the driver of the detection of an accident leading or the accident situation without passing through the server 100 by performing only step S342. To this end, a warning for an accident precursor is programmed to analyze the driving pattern of the driver in the accident detection device 200 or the user terminal 300, and is implemented to provide direct feedback. In addition, the server 100 does not simply perform the role of a repeater, but when a vehicle enters an area where a number of users cause an accident or an area where a lot of sudden start and stop occurs, the accident detection device 200 or A warning may be provided to the driver to prepare for an unexpected situation through a speaker provided in the user terminal 300.

5 is a diagram showing an example of a situation that can be recognized by the accident detection device 200 according to an embodiment of the present invention.

Referring to FIG. 5, the state of the vehicle ultimately notified by the accident detection device 200 to the server 100 may be an accident precursor situation 510 and an accident occurrence situation 520.

First, the accident precursor situation 510 may be determined by rapid deceleration or acceleration.

The sudden deceleration is generated by the brake pedal, and occurs in the state of the driver's carelessness, recognition of an unexpected situation while driving, and retaliatory driving.

If the first sensing signal is a signal generated by rapid deceleration, a request for driving attention of the vehicle is included in the accident warning signal.

Conversely, the sudden acceleration is generated by the accelerator pedal, and is generated by the driver's reckless driving or overspeed driving, and the accident warning signal may include a request for deceleration of the vehicle and provided to the driver.

The accident occurrence situation 520 is determined according to whether the second sensing signal is received or the driver operates the emergency help button.

The accident occurrence situation can be detected by receiving a second sensing signal after the first sensing signal or by receiving only a second sensing signal. In an additional embodiment, the first sensing signal is detected after the second sensing signal, so that the server 100 You may be aware that an accident has occurred.

6 is a diagram showing an example of a warning provided to a driver according to an embodiment of the present invention.

Referring to FIG. 6, a level of a warning may be calculated according to a type of a received sensing signal, a vehicle speed, and a situation that may be sensed imposedly.

For example, the'observation' grade may include a warning to remind the driver that you should be careful about driving, and the'confirmation' grade indicates a condition in which an accident occurs and a warning is issued but an additional operation command can be received from the user do. Lastly, in the case of an'emergency', it can be a warning in a situation in which the driver has to request external help automatically because the driver is in a dangerous state and cannot perform a separate operation command.

Observation-level warnings, for example,'Capture driving caution signals! There may be a warning message saying,'Please be careful with vehicle operation for safe driving!', it receives the first sensing signal including information on rapid deceleration, and is generated when the vehicle is driving at low speed.

Confirmation grade warnings include, for example,'Catch an accident caution signal! If you need help, please press the button!' In this case, when the first sensing signal including the rapid acceleration information and the rapid deceleration information is simultaneously received multiple times, it is determined that the driver is driving to avoid an accident, and a warning is issued.

Finally, the representative warning of the emergency level is'Catch an accident signal! If there is no safety confirmation response within a certain time, there may be a rescue request process. At this time, the warning of the emergency level may be a warning for notifying the outside personnel of the vehicle rather than the driver. When the server 100 receives the second sensing signal, it is determined that the vehicle directly has an accident and calculates the emergency level.

An embodiment of the present invention may also be implemented in the form of a recording medium including instructions executable by a computer, such as a program module executed by a computer. Computer-readable media can be any available media that can be accessed by a computer, and includes both volatile and nonvolatile media, removable and non-removable media. Further, the computer-readable medium may include a computer storage medium.
