1 is a schematic diagram of a drowsy driving prevention and a safety maintenance system in a vehicle 300 according to an embodiment of the present invention.

Drowsiness during driving is a phenomenon that frequently occurs, and if the driver appears to be drowsy, he or she must act after chasing a drowsiness, or take a break after parking or stopping a car to chase drowsiness and drive.

However, drowsy driving is a phenomenon that the driver himself or herself does not know, and this often leads to accidents even though drowsiness is driving, which can lead to accidents.

Various methods for preventing or solving the driver's drowsiness driving phenomenon have been disclosed, but in the process of waking the driver's drowsiness, there may be cases in which the driver is surprised. Most of the time you fall into sleepiness sooner or later.

Accordingly, the present applicant has devised the present invention to solve this phenomenon naturally and to cope with various safety problems that may occur in the vehicle 300.

In the present invention, the computer of the server 100 monitors the driver's status in real time as shown in FIG. 1, and thereby determines the driver's status in real time.

The server according to an embodiment of the present invention collects information on the driver's condition and monitors the driver's condition in real time, thereby determining the driver's condition in real time.

Then, when the computer of the server 100 determines that the driver is in a drowsy state as a result of determination, the driver may be drowsy by providing the driver with an awakening mode, or by calling a phone to the driver's terminal 200 and providing a chatbot callback service. Chase and return to normal so you can drive safely.

At this time, in order to prevent the driver from being surprised or passing a temporary effect like the previously disclosed technologies, the present invention allows the voice chatbot 130 to make a call through the terminal 200 and continue the conversation with the driver through voice. Therefore, the driver can effectively chase drowsiness through effects such as talking to a passenger or calling a friend.

More details of the embodiments of the present invention for exerting such effects will be described in more detail with reference to the drawings below.

2 and 3 are flowcharts of a method for preventing drowsy driving and maintaining safety in a vehicle 300 according to an embodiment of the present invention, and FIG. 4 is for investigating a warning message behind the vehicle 300 according to an embodiment of the present invention It is an exemplary diagram illustrating this.

2 to 4, a method for preventing drowsy driving and maintaining safety in the vehicle 300 according to an embodiment of the present invention will be described.

First, when determining that the driver's state is the first drowsiness state, the determination unit 110 of the server 100 provides an awakening mode to the driver. First warning step (step S510)

At this time, the awakening mode means that the server 100 awakens the driver by controlling the vehicle 300 or various members and devices interlocked in the vehicle 300.

More specifically, it may include radio operation in the vehicle 300, operation of air conditioning and heating devices, opening and closing windows, playing music through the driver's terminal 200, and providing an accident case through the terminal 200.

At this time, the accident case may include an accident case due to drowsy driving or an accident case occurring near the current location of the vehicle 300.

To this end, various accident cases due to drowsy driving may be stored in the database 120 of the server 100, and various accident cases may be stored by region or location. As described above, a specific accident case may be selected through data stored in the database 120 and output through the driver's terminal 200.

In one embodiment, when the awakening mode, the server 100 may operate the radio of the vehicle 300, and if the radio or music is already playing, the volume may be increased to allow the driver to awaken.

In addition, the server 100 may allow the driver to awaken by repeating the operation of opening and closing the window of the vehicle 300.

In addition, a predetermined vibration may be generated in the vibration device provided in the driver's seat, or the emergency light of the vehicle 300 may be blinked.

At this time, when the first drowsiness state of the driver is maintained for a predetermined time or more, the determination unit 110 of the server 100 may determine the state of the driver as the second drowsiness state. Specifically, when the driver does not awaken from the first drowsy state, it means that the driver is still determined to be drowsy and judged to be the second drowsy state.

As another example, the determination unit 110 of the server 100 may determine the first drowsiness state and the second drowsiness state through the driver's drowsiness level, wherein the second drowsiness state is more drowsiness than the first drowsiness state. It may be in a state where the degree is judged to be severe.

At this time, a description will be given of determining the driver's drowsiness. Various methods may be applied to the determination unit 110 of the server 100 to determine the drowsiness state.

For example, by analyzing the captured image of the driver collected from the photographing device provided inside the terminal 200 or the vehicle 300, when the angle of the upper body and the head of the driver is less than or equal to a threshold, it is determined that the driver is in a drowsy state It can determine the degree of drowsiness depending on the angle of the upper body and the head.

In addition, the determination unit 110 may recognize the size of the pupil on the driver's face, and determine that the driver is in a drowsy state when it is detected that the driver's eyelid is closed. At this time, the degree of drowsiness can be determined according to the frequency and time of the eyelid winding.

In addition, the determination unit 110 calculates a first angle with respect to the lane of the road on which the driver's vehicle 300 is driving and the traveling direction of the vehicle 300, and in the state where the direction indicator light of the vehicle 300 is turned off. When the first angle exceeds the threshold, it may be determined that the driver is not accurately controlling the steering wheel in a drowsy state.

As described above, since there are various methods for determining the driver's drowsiness state, it can be applied to determine the driver's drowsiness state.

Then, the determination unit 110 of the server 100, when the driver's state is determined to be the second drowsiness state, calls to the terminal 200, and the voice chatbot 130 to communicate with the driver through the terminal 200 do. Second warning step (S520 step)

One of the ways a driver can awaken from drowsiness is to talk to a passenger, but if there is no passenger or the passenger is also in a drowsy state, the driver cannot awaken in this way.

Accordingly, the present invention aims to make a call to the terminal 200, and to awaken in a drowsy state by exchanging and receiving conversations as if a driver actually communicates with a person.

To this end, the voice chatbot 130 does not provide information in one direction, but analyzes the driver's big data to select the conversation content and to start a conversation with the driver. Then, the driver's response message may be analyzed to provide an interactive message.

More specifically, the voice chatbot 130 analyzes one or more of the driver's age, gender, interests, occupation, and hobbies stored in the database 120 to determine a voice message and provides it through the terminal 200, and voice It is characterized by providing an interactive message by analyzing the driver's response message to the message.

At this time, the response message means the driver's voice input to the terminal 200, and the voice chatbot 130 analyzes the response message to determine the next voice message and provides it through the terminal 200.

For example, the voice chatbot 130 may search the external server 100 or the database 120 to select articles related to the driver's job, recent news, and provide the driver with an interactive message.

In addition, the voice chatbot 130 may search the external server 100 or the database 120 to select articles related to the driver's hobby, recent news, and provide the driver with an interactive message.

In more detail, for example, an interactive message may be provided to the driver about the driver's favorite soccer club, the game content of the recent game of the baseball team, the content of the player, the performance of the player, and the like.

In one embodiment, the analysis unit 140 of the server 100 may analyze the driver's voice through communication between the driver and the voice chatbot 130 and update the driver's status. The server 100 uses this to calculate the weight of a conversation topic that the driver wakes up from a drowsy state, and a conversation topic that cannot be awakened, and learns the voice chatbot 130 based on this, thereby conversing on a topic that the driver awakens. You can try.

Second warning step (step S520) Next, the analysis unit 140 of the server 100 analyzes the voice chatbot 130 and the driver's communication and the driver's state, and updates the driver's state (step S530) , When the updated driver's state is drowsy, selecting a resting space capable of parking or stopping located at a short distance from the vehicle 300 and further setting a navigation destination as the resting space (step S540). can do.

The analysis unit 140 of the server 100 means updating the driver's status information by analyzing the communication between the voice chatbot 130 and the driver. More specifically, the driver's voice is analyzed to analyze the driver's voice and the driver is still drowsy. If it is determined to mean that it proceeds to step S540.

In addition, when the analysis unit 140 of the server 100 determines that the driver is still drowsy by means or an algorithm for determining drowsiness, in addition to the communication between the chatbot and the driver, it means to proceed to step S540.

Then, the search unit 150 of the server 100 selects a resting space capable of parking or stopping at a short distance from the current location of the driver's vehicle 300, and sets the destination of the navigation to the selected resting space.

At this time, it is suitable to select the resting space as the shortest distance, and since the resting space at the shortest distance may be opposite to the traveling direction of the vehicle 300, the resting space is selected in consideration of the traveling direction of the vehicle 300 It is desirable to do.

In addition, the search unit 150 of the server 100 may set the destination of the navigation in use by the driver, may set the navigation provided in the vehicle 300, or may set the navigation of the terminal 200.

In addition, the search unit 150 of the server 100 may set a destination after activating the navigation when the driver is not using the navigation.

In this case, analyzing the driver's state through communication between the driver and the voice chatbot 130 may compare and analyze the driver's basic voice stored in the server 100 and the voice of the communication.

For example, the analysis unit 140 of the server 100, if the driver's voice is not clear, the words are blurred, or if the contents of the conversation of the voice chatbot 130 are continuously related, the driver is drowsy It can be judged to be in a state.

As an embodiment, next to the second warning step (step S520), the voice chatbot 130 and the driver's communication and the driver's state are analyzed to change the tone or intonation of the chatbot when the driver's drowsiness is not improved. Or, it may further include a third warning step to change the chatbot's honorific to half-word, or to include profanity in the chatbot's voice message.

Voice chatbot 130 may be determined by considering the driver's age, gender, voice, tone, intonation, or may be set directly by the driver.

And, despite the communication between the voice chatbot 130 and the driver, if the driver's drowsiness continues even after a certain period of time, the server 100 changes the tone or intonation of the voice chatbot 130 or changes the honorifics in half. Or, by including profanity in a voice message, the driver can be stimulated more so that he can be awakened from drowsiness.

In one embodiment, the collection unit 160 of the server 100 is one or more other vehicles located around the vehicle 300 through the image taken from the imaging device (not shown) provided outside the vehicle 300 of Unzanja Collecting the number for each first cycle, setting the corresponding vehicle 300 number as a surrounding vehicle, and if the driver's condition is determined to be the second drowsiness state or the third drowsiness state, the number of surrounding vehicles set based on the current time It may further include the step of inquiring the terminal 200 of the driver, and providing the first warning message to the terminal 200 by the warning unit 170 of the server 100.

For example, when the first cycle is set to 1 minute, it is determined that the vehicle 300 set as the surrounding vehicle within 1 minute is still around the driver's vehicle 300, and the vehicle 300 A first warning message may be provided to the driver terminal 200.

As an example of the first warning message, the message "There is a vehicle 300 in a drowsy driving around there, so be careful about driving."

In addition, a method of recognizing a number in a commonly used image may be used for the number recognition of the vehicle 300.

In addition, the third drowsiness state may be a case in which the second drowsiness state is maintained for a predetermined time or more when the driver determines that the degree of drowsiness is greater than the second drowsiness state.

In one embodiment, when the warning state 170 of the server 100 determines that the driver's condition is the second drowsiness state, the second warning message is displayed through the laser device (not shown) provided at the rear of the vehicle 300 of the driver. It may further include the step of investigating.

More specifically, the warning unit 170 of the server 100 calculates position information and speed information of the rear vehicle 330 from the image captured through the camera provided at the rear of the driver's vehicle 300, and uses the laser device. By controlling, the second warning message may be irradiated on the front road surface of the rear vehicle 330.

The warning unit 170 of the server 100 may allow a second warning message to be irradiated on the road surface through a laser device provided behind the driver's vehicle 300 as shown in FIG. 4.

At this time, by calculating the position information and speed information of the rear vehicle 330 from the image taken through the camera as described above, and by controlling the laser device to irradiate the second warning message on the front road surface of the rear vehicle 330, the rear It is desirable to allow the driver of the vehicle 330 to easily check the warning message.

Like the first warning message mentioned above, the second warning message may be applied with a warning message to warn that the driver of the corresponding vehicle 300 is drowsy driving.

In one embodiment, the analysis unit 140 of the server 100, the driver does not receive a call from the terminal 200, or if the driver does not answer the voice message of the voice chatbot 130, the driver Determining the state of the dangerous state, and outputs a warning sound through the driver terminal 200, the disaster management server 100 of the driver's information, vehicle 300 information and one or more of the location of the vehicle 300 It may include the step of transmitting.

The analysis unit 140 of the server 100, when the driver does not receive a phone call sent to the terminal 200, the driver receives a call but does not respond to the message of the voice chatbot 130, the driver's drowsiness It means that the condition is judged to be serious or an emergency, and the driver's condition is considered to be dangerous.

In this case, a warning sound is output through the driver terminal 200, the report is received by the disaster management server 100 such as 119 and 112, and the driver's information, the vehicle 300 number, and the vehicle 300 location are transmitted. You can do it.

Then, when the driver's condition is determined to be in a dangerous state, the driver's vehicle 300 is changed to an autonomous driving mode, or the emergency light of the vehicle 300 is turned on, the vehicle 300 is decelerated, and then stopped. Deceleration is controlled in consideration of the state of the road where the vehicle 300 is located or the state of the surrounding vehicle 300.

In one embodiment, when the analysis unit 140 of the server 100 detects the impact or noise of the vehicle 300 or more than the preset reference value in the safety device 310 provided inside the vehicle 300, the driver terminal Providing a warning message to (200), if there is no driver's confirmation of the warning message for the first time, the driver's information, vehicle 300 number and location of the vehicle 300 to the disaster management server 100 , In the event of an impact, the method may further include transmitting one or more of the recorded images.

In one embodiment, when the start of the vehicle 300 is turned off, the safety device 310 provided in the vehicle 300 checks the occupants in the vehicle 300, within the vehicle 300 When a passenger is present, the server 100 transmits a warning message to the driver terminal 200, but outputs a warning sound through the driver terminal 200 when the preset time is exceeded and the vehicle 300 through the disaster network It may further include the step of receiving a report on the location and the number of passengers.

In many cases, the driver blinks and releases a young child in the vehicle 300. In such a case, the child is not likely to come out of the vehicle 300, or even if it exits the vehicle 300, it is very likely to be in another dangerous situation. .

In particular, in summer or winter, since the time itself for a small child to stand in the vehicle 300 is imminent, the probability that a dangerous thing will occur to a small child in a short time when the driver blinks becomes very high.

Accordingly, according to an embodiment of the present invention, when the safety device 310 provided in the vehicle 300 is turned off, the vehicle 300 checks whether or not a passenger is present, and the driver terminal 200 ), and if there is no response to the warning message, or if there are still boarding personnel in the vehicle 300, it is judged that the person (young child, the elderly, etc.) was released and the report can be filed through the disaster network. To make.

At this time, the safety device 310 provided in the vehicle 300 may be any device that can confirm whether or not the number of people in the vehicle 300 is occupied, and the photographing device in which the analysis unit 140 photographs the inside of the vehicle 300 It is also possible to check the number of passengers by analyzing the captured images of.

In addition, in the embodiment of the present invention, a disaster network is applicable to any institution or company that can receive a report in a specific danger situation, such as a police station, a fire department, or a private security company and promptly dispatch it to the scene.

In one embodiment, when an accident is detected during parking or stopping of the vehicle 300, the location information of the vehicle 300, boarding in the vehicle 300 checked by the safety device 310 provided in the vehicle 300 It may further include the step of transmitting at least one of the damage levels of the vehicle 300 determined through the personnel and the safety device 310 to the disaster network and receiving the report.

At this time, the safety device 310 includes one or more sensors provided (installed) in the vehicle 300, and detects whether there is an accident in the vehicle 300 using information such as shock and noise collected through the sensor, The degree of impact applied to the vehicle 300 may be calculated.

More specifically, the determination unit 110 may determine whether to accept the report through the degree of impact applied to the vehicle 300 measured through the safety device 310.

For example, the magnitude of the impact applied to the vehicle 300 is set in steps 1 to 5, and if it belongs to steps 1 and 2, it may be judged as a simple contact accident and the report may not be accepted, and the impact is in step 3 If it belongs to the above, it is possible to determine that the driver and the occupant have been injured by the impact applied to the vehicle 300 and to file a report.

In addition, when the server 100 reports to an emergency facility such as 119, it checks the occupants checked through the safety device 310 and transmits information about the occupants in the vehicle 300 to dispatch an ambulance. To be able to.

5 is a diagram illustrating an operation when the driver does not receive a call from the terminal according to an embodiment of the present invention.

In FIG. 2, when the driver cannot return to the normal state in the first warning step, a voice chatbot service is provided through the second warning step.

At this time, if the driver does not receive the call of the terminal, it is determined that the driver's drowsiness is severe or the driver has fallen into a dangerous state such as a fainted state, and the countermeasure must be taken.

More specifically, in the second warning step (step S520) of FIG. 2, when the determination unit of the server determines that the driver's state is the second drowsiness state, a call to the terminal of the driver (step S523), the driver calls the terminal. When receiving, the voice chatbot provides a voice chatbot service to the terminal to communicate with the driver (step S525).

At this time, if the driver does not receive a call from the terminal for more than a predetermined time, the server outputs a warning sound through the driver terminal, and transmits at least one of the driver's information, the vehicle number, and the location of the vehicle to the disaster network. (Step S527)

In addition, the server collects information from the driver's terminal and navigation, and transmits information about the current location of the driver's vehicle, as well as the destination and current route, to the disaster network, where emergency dispatch vehicles, police, ambulance, and 119 are dispatched to the location. Can be quickly identified.

6 is a view illustrating a check for the occupants in the vehicle according to an embodiment of the present invention.

Referring to FIG. 6, a method for preventing drowsy driving and maintaining safety in a vehicle according to an exemplary embodiment of the present invention may further include the following steps.

When the start of the driver's vehicle is turned off, a safety device provided in the vehicle checks the occupants in the vehicle.

Then, when there is a passenger in the vehicle, a warning message is transmitted to the terminal of the driver.

At this time, when a preset time is exceeded, a warning sound is output through the driver terminal, and a report on the location of the vehicle and the number of passengers is received through the disaster network.

In the vehicle, a baby, a child, an elderly person, etc. ride, but the driver often flickers and leaves the passenger in the vehicle. At this time, in the summer and winter, even for a short period of time, the condition of the baby, child, and the elderly becomes dangerous or even in severe cases, leading to death.

Through this, the driver can check the warning message received by the terminal and quickly return to the vehicle.

If the driver cannot confirm the warning message, the server outputs a warning sound to the driver terminal to cause the driver to confirm the terminal, and reports to the disaster network so that the police, 119, and the like can be dispatched urgently.

At this time, the server sends information such as the number of passengers and the location of the vehicle together to prevent errors.

In addition, when an accident is detected while parking or stopping the vehicle, the server grasps the location information of the vehicle, the occupants of the vehicle checked by the safety device provided in the vehicle, and the degree of damage to the vehicle determined through the safety device. Send information to the disaster network and file a report.

Due to such a configuration, even if an accident occurs when the driver parks or stops the vehicle, there is an effect that the server can receive a report to the disaster network.

Therefore, when the driver parks the vehicle and stays in a different location, so it is not possible to know whether the vehicle is in an accident, or when the driver is stopping and an accident occurs and it is difficult to report directly due to an injury, the report can be filed with the disaster network. There will be.
