Drunk driving is one of the main causes of impeding traffic safety. As road traffic accidents due to drunk driving show an increasing trend every year, it is urgent to prepare measures to prevent traffic accidents caused by drunk driving in advance.

As a prior art for preventing drunk driving, a system for preventing drunk driving by checking the drunk driving state of the driver twice before driving and during driving has been introduced. In this system, when the driver holds the steering wheel, a sensor attached to the vehicle analyzes the sweat component of the driver's palm to measure the alcohol concentration in the blood. As a result of the measurement, if an alcohol content higher than the standard value is detected, the vehicle's engine does not start.

At the same time as the vehicle starts, the camera installed in front of the driver's seat checks whether the driver's pupil is out of focus, and also checks whether the driver is driving zigzag when the steering wheel is operated.

After checking driver-related information through the drunk driving prevention system, if it is determined that you are driving under the influence of alcohol, the driving speed of the vehicle automatically decreases and stops.

How to prevent drunk driving

Hereinafter, the method for preventing drunk driving proposed in the present specification will be described in more detail with reference to the related drawings.

The drunk driving prevention method proposed in the present specification is largely (1) step 1 of authenticating the user (or the occupant of the vehicle or the owner of the vehicle), (2) step 2 of measuring whether or not drinking, (3) transmitting the breathalyzer result Step 3, (4) Step 4, controlled by the central server of the control center, (5) Step 5, where the control center executes follow-up actions such as surrogate operation through a counselor or central server, (6) Execution process of follow-up actions It can be divided into 6 steps to check the

Step 1

First, the user authentication step, which is the first step, is a step of verifying whether the user is in the vehicle and the identity of the vehicle occupant in the vehicle to which the drunk driving prevention device is attached.

The main technical feature of the first step proposed in this specification is to fundamentally block the measurement of alcohol by others other than the owner registered in the vehicle, and the specific method for this is as follows.

Specifically, the authentication module of the drunk driving prevention device authenticates the user himself based on the user's biometric information, such as fingerprint authentication, iris authentication, and facial authentication.

Here, fingerprint authentication, iris authentication, facial authentication, and the like may be applied to the methods proposed in the present specification by existing technologies implemented or used.

Additionally, the surroundings including the user are photographed at an angle without a blind spot through a camera (or camera module) attached in the vehicle or provided in the drunk driving prevention device to fundamentally block the surrogate breathalyzer measurement by others.

However, in photographing the surroundings including the user, a scene that is an obstacle to the identification of the user may be processed to be excluded through the image processing method currently being implemented.

Step 2

Next, the second step is to measure whether the vehicle occupant (or the user or the vehicle owner) is drinking using the drunk driving prevention device.

Specifically, the second step may be performed at the same time that the user's thumb and index finger are in contact with the fingerprint recognition module (or fingerprint recognition sensor) of the drunk driving prevention device.

In the second step, proxy measurement by someone other than the user can be fundamentally blocked. More specific details related to this will be described later.

After the alcohol consumption measurement, the measurement result value is measured through the output unit (or display unit) of the drunk driving prevention device or, when a related application is running in the user's terminal, the measurement result value through the output unit of the terminal. Outputs voice and/or text.

The measurement result value (or measurement information) output through the output unit may be simply displayed as pass or reject.

If the measurement result value is displayed as rejected, the measurement result value may also display the user's blood alcohol concentration.

And, the measurement result value is transmitted to the central server of the control center through the wireless communication unit of the drunk driving prevention device, follow-up measures may be performed by the counselor of the control center or the central server.

Step 3

The third step is a step of transmitting the result of the breathalyzer measurement measured in the second step salpin above.

The measurement result value (or measurement information) may be transmitted to the central server of the control center through a GPS module and a mobile communication network (WCDMA, LTE, 5G network).

The measurement information may include information on whether the measured blood alcohol concentration exceeds a reference value along with the blood alcohol concentration.

Then, the counselor of the control center or the central server of the control center performs follow-up actions based on the received measurement information and the situation determination manual.

Step 4

In the fourth step, the central server of the control center analyzes the measurement information received from the drunk driving prevention device and examines a method of performing follow-up measures related to drunk driving.

The central server of the control center stores information on the received breathalyzer in a database (DB). Here, the database may be expressed as a memory, a storage unit, etc. previously salpinned.

The information stored in the DB can be used later when a user's pattern analysis related to drunk driving and similar situations occur in the future.

More specifically, the measurement information about the user in relation to the drunk driving is accumulated in the DB, and can be utilized to provide a customized solution through analysis algorithms such as deep learning and artificial intelligence (AI).

Step 5

Step 5 relates to how to implement follow-up actions in the control center.

When a state of inability to drive is determined through a breathalyzer test, when a user input for a specific option is received with respect to options provided by the device for preventing drunk driving, processing proceeds according to a specified manual or a counselor may proceed.

Here, the progress according to the specified manual may be a call to a substitute engineer, a CAPS dispatch, 112, and the like.

In addition, the progress according to the designated manual may be determined according to the measured value of the user's blood alcohol concentration.

For example, if the value of the blood alcohol concentration is high (legal license revocation level), the central server can control the direct connection to 112, and if the value of the blood alcohol concentration is not high, but is not at the driving level (legal license revocation level) stop level), you can control to call a proxy driver by connecting to a proxy company.

Data related to the user's history, such as all histories related to progress according to the manual or through the counselor, may be stored in the DB of the central server.

If the follow-up action in the control center is performed by the counselor, the counselor may monitor whether the safe return procedure of the user according to each situation is proceeding properly. More detailed information about this will be looked at through step 6.

Step 6

Step 6 is a step in which the control center monitors whether follow-up procedures such as returning home of users who are unable to drive and related vehicles through a counselor or a central server are proceeding properly.

When the follow-up procedure is contacted by acquaintances such as family members or relatives, the user does not cause drunk driving and whether the user and related vehicles are being delivered normally. can be given feedback.

Preferably, the movement path of the user and the related vehicle may be monitored in real time through the related application, the acquaintance or the like may check a situation in which the follow-up procedure is properly performed, and feedback that the situation has been completed may be fed back.

Hereinafter, some steps in the first to sixth steps salpin above will be looked at in more detail.

Let's look at how the drunk driving prevention device authenticates the user in relation to the breathalyzer.

The drunk driving prevention device receives information about whether the vehicle door is opened and then properly closed through the in-vehicle system.

The reason such a procedure is necessary is to prevent a drunk user and another person from boarding a vehicle together to take a breathalyzer test when the vehicle door is not completely closed.

In other words, if someone other than the drunk driver is in the driver's seat, there is a high probability that the vehicle door will not close properly.

If it is detected that the user is seated in the driver's seat alone, the weight (sensing) sensor of the drunk driving prevention device is driven to measure the user's weight, and whether the measured user's weight is the same as the previously registered user's weight to judge

Here, whether the process is the same may be determined by whether the measured weight and the previously registered user's weight are within a preset weight measurement tolerance range.

The weight measurement tolerance range may be, for example, +5kg to -5kg.

When the primary authentication procedure through weight measurement for the user is terminated, the drunk driving prevention device performs the following additional authentication procedure secondarily.

In the secondary authentication procedure, when the user's driver's seat sitting state is maintained for a predetermined time, the drunk driving prevention device detects the user's identity through at least one of a fingerprint authentication module, a face authentication module, an iris authentication module, a voice authentication module, and a camera module. Additional authentication is performed.

Any one of the above salpin authentication types may be performed, or several authentication types may be performed together.

If multiple authentications are performed together (in this case, it may be desirable to perform sequentially), while the identity authentication process proceeds more accurately, there is a point that it may take a lot of time to perform the entire breathalyzing process .

If additional identification is performed using the camera module, the picture taken through the camera module of the drunk driving prevention device is transmitted to the central server of the control center.

Then, the central server may compare the photographed picture with the previously registered picture of the user to determine whether the user is the person, and transmit the determination result back to the drunk driving prevention device.

In the above salpin, iris authentication, or facial authentication, authentication may be performed according to the degree of iris blood vessels, facial flushing, etc. of the subject.

And, when the user's own authentication is completed through the primary and secondary authentication procedures, the drunk driving prevention device proceeds with a breathalyzer measurement.

Next, we will look at the breathalyzer test in detail.

First, in order to prevent the user or vehicle occupant from negatively taking a breathalyzer test, the drunk driving prevention device should be attached to the right side of the driver's seat or the right side of the steering wheel so that a surrogate alcohol test by another person is impossible while the vehicle occupant is seated in the driver's seat. may be desirable. If the drunk driving prevention device is installed on the left side of the driver's seat or on the left side of the steering wheel, the installation of the drunk driving prevention device may be unsuitable because the window of the vehicle may be easily opened and closed and thus illegal alcohol consumption measurement may be possible.

The drunk driving prevention device may be equipped with a fingerprint recognition module to enable fingerprint recognition.

As one of the secondary user authentication methods, fingerprint authentication may be performed when the user's thumb and middle finger contact are sensed by the fingerprint authentication module.

When the fingerprint authentication procedure is finished, the drunk driving prevention device receives information about respiration from the user.

Here too, in order to prevent a surrogate alcohol measurement by another person during the breath measurement, the drunk driving prevention device drives the weight sensor to measure the weight of the passenger seat in the vehicle, so that the breath measurement is illegally carried out by others can prevent

In addition, the drunk driving prevention device may drive an obstacle sensor to find a cause of an obstacle that may occur during the alcohol consumption measurement and solve the problem.

It may be preferable that the weight sensor, the obstacle sensor, etc. are measured from the left to the right first.

If the device for preventing drunk driving recognizes that another person is riding in the passenger seat next to the driver, the device for preventing drunk driving does not measure the alcohol consumption.

The weight sensor, the obstacle sensor, etc. may be implemented as a laser type sensor, for example, an ultrasonic sensor may be used.

If the above procedure is successfully performed, the device for preventing drunk driving receives information about respiration from the user for breath measurement.

Thereafter, the drunk driving prevention device analyzes the information on the respiration to generate a result value for the breathalyzer, that is, the breathalyzer information.

And, the drunk driving prevention device transmits the breath measurement information to the central server of the control center.

The central server may be implemented in the system of the control center, and cumulatively store the received breathalyzer information in the DB, and utilize the data accumulated in the DB to perform subsequent procedures in the future.

The breathalyzer information may include information on the vehicle owner (or user), information on the current or moving location of the user, time information during the breathalyzer measurement, information on the numerical value of the measurement, and the like.

And, the (drinking) measurement information can be transmitted from the drunk driving prevention device to the central server through GPS, mobile communication networks (3G, 4G, 5G, etc.), local area networks (Bluetooth, Wi-Fi, etc.).

If the transmission of the breathalyzer information fails or is delayed due to a failure, the breathalyzer information may be transmitted again after a predetermined period has elapsed.

HARQ ACK/NACK procedure defined in the mobile communication standard may be utilized for the retransmission process for the breathalyzer information as described above.

And, when the information on the alcohol consumption measurement is measured late at night (after 9 pm) or in an entertainment area (an area where bars such as Jongno, Sadang, Guro, and Gangnam are densely populated), the device for preventing drunk driving in advance You can control the SMS to be sent to the set contact.

Based on the above salpin breathalyzer information or measurement result value, the drunk driving prevention device may control whether to lock or unlock the ignition of the vehicle.

First, the drunk driving prevention device allows the vehicle to be started when the measurement result value for the breathalyzer is lower than the reference value prescribed by the law.

Alternatively, when the measurement result value for the alcohol consumption measurement is higher than the reference value, a warning message such as driving impossibility may be output through the output unit of the apparatus for preventing drunk driving.

Together with the warning message, a level of blood alcohol concentration for a breathalyzer measurement, a risk guide for drunk driving, and a plan for a follow-up procedure may be output together.

In addition, the measurement information including the warning message may be transmitted to the central center of the control center.

Thereafter, the central server analyzes the received measurement information, and when it is determined that the driving is not possible, the central server may be connected to a counselor of the control center or a preset follow-up procedure may be performed.

The preset follow-up procedure may be to make a connection with a proxy company to make a proxy operation, to have the ADT CAPS to be dispatched, or to connect to 112 or the like.

In the subsequent procedure above, specific options may be determined according to the value of blood alcohol concentration included in the measurement information.

As a result of analyzing the breathalyzer information, if the user's driving is impossible, and the counselor of the control center controls the current situation, the counselor may communicate directly with the user and guide and control each response step.

That is, the counselor can determine the current user's location through the analysis of the breathalyzer information, so that the appropriate action can be performed.

Here, all call details between the counselor and the user may be recorded. Recordings may be limited to cases that do not conflict with the law.

All details of the recording may be stored in a central server of the control center.

Next, in addition to the direct process by the counselor, follow-up procedures through surrogate driving and contact with family members will be reviewed.

More specifically, as a result of analyzing the breathalyzer information, if it is determined that the user's condition is impossible to drive, the central server of the control center drives the surrogate driving, or makes contact with family members or acquaintances such as relatives to take over the family to prevent drunk driving.

If the surrogate driving or connection with family has failed, and it is determined that the drinker's control is out of control, the ADT CAPS can be called according to predefined conditions, or call 112 to prevent the police from being dispatched. make it possible

In the case of linking with a proxy company as a follow-up procedure, the overall situation such as the progress of surrogate driving can be monitored through a related application downloaded to the user's drunk driving prevention device.

In the case where the user's drunk driving prevention device includes the related application not only for surrogate driving, but also for 112 report, CAPS dispatch, etc., the relevant situation may be confirmed through the drunk driving prevention device.

Drunk driving prevention device action

Based on the above salpin and the drunk driving prevention method, we will look at it in more detail from the viewpoint of the operation of the drunk driving prevention device.

First, when the door of the driver's seat of the vehicle is opened and the door of the driver's seat is completely closed, the drunk driving prevention device is operated.

Here, the meaning that the drunk driving prevention device is operated may include that all sensors included in the drunk driving prevention device salpin above are operated (or turned on).

More specifically, when detecting that the user is seated in the driver's seat, the drunk driving prevention device operates the weight sensor.

If it is not detected that the user is seated in the driver's seat, the weight sensor of the drunk driving prevention device does not operate.

Then, the weight sensor of the drunk driving prevention device measures the weight of the occupant of the driver's seat.

The weight sensor simultaneously detects a change in the weight of the passenger seat next to the driver's seat, thereby preventing the occurrence of a breathalyzer measurement by another person in advance.

The weight sensor compares the measured value of the weight of the occupant of the driver's seat with the weight of the user registered in advance, and controls not to start the vehicle if they do not match within a certain range.

The reason why it is limited to the case that they do not match within the above range is because some errors may occur between the weight of the occupant measured in real time and the weight of the user registered in advance.

As an example, it may be -5kg to +5kg within any of the above ranges. However, a threshold value within the above range is defined, and the threshold value may be changed by a user's setting.

The reason is that the weight of the user registered in advance by the user's setting for the accurate determination of the apparatus for preventing drunk driving can be updated because the user's weight can be significantly changed within a short time.

Alternatively, when it is determined that the weight value measured during the breathalyzer measurement is accurate, the weight value of the user registered in advance with the corresponding value may be updated.

Thereafter, when the weight measurement by the weight sensor of the drunk driving prevention device is successful, biometric authentication may be additionally performed through the biometric authentication module of the drunk driving prevention device. Similarly, when biometric authentication fails, the drunk driving prevention device prevents the vehicle from starting.

In addition, the biometric authentication may include fingerprint authentication, face authentication, iris authentication, voice authentication, and the like, and may be performed separately from the fingerprint authentication, face authentication, iris authentication, and voice authentication.

If performed separately, each of the fingerprint authentication, face authentication, iris authentication, and voice authentication is provided with each module and may be performed by each provided module.

If biometric authentication, fingerprint authentication, and face authentication are performed separately, fingerprint authentication, face authentication, etc. may be performed after biometric authentication.

For example, the fingerprint authentication may be performed when information on a user's thumb and index finger fingerprints is input.

Hereinafter, for convenience of explanation, biometric authentication will be expressed as primary authentication, and authentication after biometric authentication will be expressed as secondary authentication.

For example, if the primary authentication succeeds, the secondary authentication is performed, and the secondary authentication fails, the engine is not started.

If the secondary authentication (or additional authentication) is successful in the authentication module, the drunk driving prevention device drives the breathalyzer module.

The drunk driving prevention device continuously monitors the user's weight by simultaneously operating the weight sensor while the alcohol consumption measurement is in progress. This procedure may be implemented by the processor of the drunk driving prevention device.

Here, the reason for continuously monitoring the weight of the user is to monitor whether the measurer has departed from the seat and to prevent the occurrence of negligence of the alcohol consumption measurement by others.

More specifically, while the breathalyzer measurement is in progress, the weight measurement by the weight sensor measures a change in the weight of not only the driver's seat but also the passenger seat next to it.

If the value measured in the passenger seat changes larger than the threshold value, the drunk driving prevention device locks the ignition of the vehicle.

Alternatively, the measurement of the weight of the passenger seat may continuously check whether the seat is vacant by using a camera attached to the vehicle, in addition to the change in weight measurement.

If there is no abnormality in the measurement of the weight of the passenger seat (or there is no change in weight), the apparatus for preventing drunk driving may detect an object on the passenger seat through a camera module.

Instead of the camera module, a motion detection sensor may be used for motion detection, and the motion detection sensor may include the camera module.

Similarly, when an object is detected in the passenger seat by the motion detection sensor, the drunk driving prevention device locks the engine start of the vehicle.

The reason is to fundamentally prevent the denial of the alcohol consumption measurement from the passenger in the passenger seat.

Thereafter, the drunk driving prevention device transmits information on the alcohol consumption measurement, that is, the measurement information to the central server of the control center through a mobile communication network.

The transmission of the measurement information may be performed through a wireless communication module of the drunk driving prevention device.

The measurement information may also include a photograph taken by the camera module during the breath measurement.

Thereafter, the central server analyzes the measurement information to determine whether the user is intoxicated or not, and when it is determined that the user is unable to drive, a follow-up action may be performed.

As salpin, follow-up actions may be a connection with a counselor at the control center, connection of a surrogate driver, dispatch of ADT CAPS, 112 call, etc., and such follow-up actions may be based on preset options and/or of blood alcohol concentration included in the measurement information. It can be performed according to the value.

In addition, the process or information transmitted and received between the central server and the drunk driving prevention device may be performed through a dedicated application related to the drunk driving prevention.

Next, the steps of performing follow-up actions without the intervention of the counselor through the counselor of the control center or through the control module of the central server will be looked into in detail.

First, the counselor attempts to contact the occupant (or user) of the vehicle. Without the intervention of the counselor, the processor of the central server attempts to contact the user through the relevant application.

If there is no contact for a certain period of time from use, the procedure of (1) to be described later is performed, and when contact is made with the user, options for follow-up actions such as surrogate operation may be provided according to the user's condition. And, thereafter, the procedure (2) may be performed.

Prior to the procedure of (1), if the user is contacted, look at the subsequent procedure, that is, the procedure of (2).

The counselor or the processor of the central server may analyze the user's condition and cause follow-up actions to occur as a substitute driving to prevent drunk driving.

If the user's condition is not accurately determined, the drunk driving prevention device may lock the ignition of the vehicle.

If the user selects the option of driving by proxy, the counselor or the processor of the central server calls the driver and delivers information about the user to the driver or the agent.

Here, when it is sensed that the vehicle is delivered by the surrogate driver, the drunk driving prevention device unlocks the locked ignition.

Next, look at the procedure of (1).

If the user cannot be contacted, the counselor or the processor of the central server connects to the pre-registered contact network (or emergency contact network).

When connected to the emergency contact network, a person corresponding to the contact network may be informed of the current situation, and an option for follow-up may be selected.

When the input from the person corresponding to the contact network or the person corresponding to the contact room determines the proxy operation, the counselor or the processor of the central server connects to the agent company and provides information about the user.

If it is not connected to the emergency contact network, the counselor or the processor of the central server can i) call ADT CAPS or ii) call 112.

4 is a flowchart illustrating an example of a method for preventing drunk driving proposed in the present specification.

Next, the drunk driving prevention device receives information related to the occupant's breathing (S440).

Next, the drunk driving prevention device outputs the measurement information visually, auditory or tactilely (S450).

Next, the drunk driving prevention device transmits a second signal including measurement information related to a breathalyzer to the central server of the control center (S460).

More specifically, the apparatus for preventing drunk driving compares the weight of the occupant measured by the first sensor with a preset weight of the occupant, and according to whether or not the self-authentication of the occupant performed by the second sensor is successful Controls the vehicle's start.
