Description

Vehicle drunk driving prevention device and method of operation {APPARATUS FOR PREVENTING DRIVING UNDER THE INFLUENCE OF VEHICLE AND OPERATING METHOD THEREOF}

The present invention relates to a drunk driving prevention device for a vehicle and a method of operating the same, and more specifically, to a vehicle applied to a drunk driving prevention system that prevents drunk driving by measuring the drunk driving state of the occupants. The present invention relates to a vehicle drunk driving prevention device and its operating method that effectively prevents drunk driving by detecting fraudulent activity that evades the function and restricting the vehicle's driving function.

Drunk driving is a crime and can cause serious casualties, so governments around the world are trying various efforts to prevent drunk driving.

The U.S. state of California passed an amendment mandating the installation of ignition interlock devices on vehicles of drunk drivers across the state starting in July 2017, and currently, 25 states have mandated the installation of ignition interlock devices for all drunk drivers. In Europe, provisional regulations have been approved to promote the installation of alcohol interlocking devices in new and existing vehicles from May 2022.

The drunk driving prevention system currently applied to vehicles determines whether the driver is drinking by measuring the blood alcohol concentration through exhaled breath or measuring the blood alcohol concentration by illuminating the capillaries of the finger.

The background technology of the present invention is disclosed in Republic of Korea Patent Publication No. 10-1997-0005799 (published on February 19, 1997).

The method of determining whether a driver is drinking by acquiring his or her biometric signals has the limitation of being vulnerable to fraud that intentionally attempts to evade the function of the drunk driving prevention system. For example, after measuring the state of drinking through a person who is not drunk but in a normal state to activate the vehicle's starting and driving functions, the function to detect the illegal act of driving the vehicle while drunk is a function of conventional drunk driving. There is no prevention system in place. Therefore, in order to fundamentally block drunk driving, it is necessary to apply a function that can detect misconduct such as 'changing driver after measurement' or 'using biometric signals of other passengers' as described above.

The present invention was created to solve the above-mentioned problems, and the purpose of one aspect of the present invention is to effectively prevent drunk driving by detecting fraudulent activities that avoid the function of the drunk driving prevention system and limiting the driving function of the vehicle. The purpose is to provide a device for preventing drunk driving in a vehicle and a method of operating the same.

According to one aspect of the present invention, a device for preventing drunk driving of a vehicle includes a physical information detection unit that detects physical information of a passenger riding in a target vehicle, a breathalyzer unit that measures the drinking state of the occupant, and a device that detects driving information of the target vehicle. A driving information detection unit, and a control unit connected to the physical information detection unit, the breathalyzer unit, and the driving information detection unit, wherein the control unit detects a basic driver pre-registered in the target vehicle and is detected through the body information detection unit. Using the physical information of the subject, driving authority is granted to the target driver who currently wishes to drive the target vehicle, and if the measurement target is determined to be not in a drunken state based on the measurement results of the breathalyzer, the driving function of the target vehicle is activated. Activate, and in the driving process of the target vehicle, based on the driving information detected by the driving information detection unit or the body information detected by the body information detection unit, the current driver of the target vehicle and the measurement subject are mismatched. It is characterized in that it detects an illegal act and restricts the driving function of the target vehicle when it is determined that the illegal act has been detected.

In the present invention, the body information detected by the body information detection unit includes the occupant's weight information and face information.

In the present invention, when the basic driver wants to drive the target vehicle as the target driver, the control unit references the basic driver's body information currently detected through the body information detection unit and the basic driver's body stored in advance. The information is compared and, if there is a match, driving authority is granted to the basic driver.

In the present invention, the control unit determines that the driving information detected by the driving information detection unit during the driving process of the target vehicle is stored in advance on the basis of the basic driver's past driving history for the target vehicle. If the driving pattern deviates from the driving pattern, it is determined that the misconduct has been detected.

In the present invention, when a third party other than the basic driver wishes to drive the target vehicle as the target driver, the control unit provides one of the physical information of the basic driver and the history information of the third party driving the target vehicle. Using the above, driving authority is granted to the third party only for the currently targeted driving of the target vehicle.

In the present invention, the control unit determines that the misconduct has been detected when a change in the body information detected by the body information detection unit is detected during the driving process of the target vehicle.

In the present invention, the target vehicle is a shared vehicle, the basic driver is a reserved driver who is pre-registered in the target vehicle and has reserved the use of the shared vehicle, and the control unit is configured to detect the information currently detected through the body information detector. The physical information of the basic driver is compared with the physical information of the basic driver registered at the time of reservation of the shared vehicle, and if they match, driving authority is granted to the basic driver.

In the present invention, the control unit receives the driving pattern of the basic driver, which is secured in advance based on the basic driver's past driving history with respect to the vehicle owned by the basic driver, from the outside, and When the driving information detected by the driving information detection unit deviates from the received driving pattern, it is determined that the misconduct has been detected.

In the present invention, when the basic driver does not own a vehicle, the control unit determines that the misconduct has been detected when a change in the body information detected by the body information detection unit is detected during the driving process of the target vehicle. It is characterized by

In the present invention, when it is determined that the misconduct has been detected, the control unit restricts the driving function of the target vehicle by outputting a warning and limiting the vehicle speed of the target vehicle to a predefined minimum speed. It is characterized by

A method of operating a vehicle drunk driving prevention device according to an aspect of the present invention includes the control unit currently detecting the target vehicle using the basic body information of the driver pre-registered in the target vehicle, which is detected through the body information detection unit. Granting driving authority to a target driver who wishes to drive, the control unit, activating a driving function of the target vehicle when the control unit determines that the measurement subject is not in a drunk state based on the measurement results of the breathalyzer, the control unit a. During the driving process of the target vehicle, the current driver of the target vehicle and the measurement subject do not match based on the driving information detected by the driving information detection unit or the body information detected by the body information detection unit.

Figure 2 is a flowchart for explaining the operation method of a vehicle drunk driving prevention device according to an embodiment of the present invention.

Hereinafter, a vehicle drunk driving prevention device and its operating method according to the present invention will be described with reference to the attached drawings. In this process, the thickness of lines or sizes of components shown in the drawing may be exaggerated for clarity and convenience of explanation. In addition, the terms described below are terms defined in consideration of functions in the present invention, and may vary depending on the intention or custom of the user or operator. Therefore, definitions of these terms should be made based on the content throughout this specification.

FIG. 1 is a block diagram for explaining a device for preventing drunk driving in a vehicle according to an embodiment of the present invention, and FIG. 2 is a flowchart for explaining an operation method of a device for preventing drunk driving in a vehicle according to an embodiment of the present invention. am.

Referring to Figure 1, a vehicle drunk driving prevention device according to an embodiment of the present invention may include a body information detection unit 100, a breathalyzer 200, a driving information detection unit 300, and a control unit 400. there is.

The physical information detection unit 100 can detect physical information of a passenger seated in the target vehicle, and in this embodiment, can detect physical information of a passenger seated in the driver's seat. The body information detected by the body information detection unit 100 may include the occupant's weight information and face information. For this purpose, the body information detection unit 100 is a weight sensor provided on the driver's seat to detect the occupant's weight information. It may include 110 and a camera sensor 120 that is provided at a predetermined location inside the vehicle (e.g., a rearview mirror) and detects facial information of the occupant by capturing an image of the occupant's face. The above physical information can be used in the process of granting driving authority to the target driver who wishes to drive the target vehicle and in the process of detecting misconduct while driving the target vehicle.

The breathalyzer 200 can measure the driver's drinking status by measuring alcohol concentration. The breathalyzer 200 is installed on the door or steering wheel of the target vehicle, absorbs the exhaled breath of the occupant, analyzes it with infrared rays, and uses the fact that the amount of infrared rays absorbed by carbon dioxide and alcohol is different to detect alcohol according to the absorption rate. A breath alcohol sensor (210) that measures the concentration, and a contact alcohol sensor (220) provided on the start button or steering wheel of the target vehicle that irradiates near-infrared rays when touched by the passenger's fingers and reads the spectrum to measure blood alcohol concentration ) may include one or more of the following. The occupant's drinking status measured as described above can be used in the process of activating the driving function of the target vehicle.

The driving information detector 300 may detect driving information of the target vehicle. Driving information may include the acceleration of the target vehicle and the distance between the target vehicle and the preceding vehicle, but is not limited to this and may include various information indicating the driving state of the target vehicle, such as the vehicle speed of the target vehicle. To this end, the driving information detector 300 may include a vehicle speed sensor 310, an acceleration sensor 320, and a distance detection sensor 330 (eg, an ultrasonic sensor, a radar sensor, a camera sensor, etc.). The above driving information can be used in the process of detecting misconduct while driving the target vehicle.

The control unit 400 is connected to the physical information detection unit 100, the breathalyzer 200, and the driving information detection unit 300, respectively, and may function as a control device that integrates and controls a drunk driving prevention function to be described later. The control unit 400 may be implemented as a processor or SoC (system on chip) that performs processing and calculation of various data, and processes instructions or data received from other components by loading them into memory. and can be designed to store various data in memory.

Based on the above-described content, the following will focus on the operation of the control unit 400 to detect fraudulent activity that avoids the drunk driving prevention function through the breathalyzer 200 and limit the driving function of the target vehicle. Explain in detail.

First, the control unit 400 may grant driving authority to the target driver who currently wants to drive the target vehicle using the basic driver's physical information detected through the body information detection unit 100 and pre-registered in the target vehicle.

Here, the basic driver pre-registered in the target vehicle may refer to the owner of the target vehicle, and the target driver may refer to the driver who currently wishes to drive the target vehicle. In this embodiment, the control unit 400 operates when the primary driver wishes to drive the target vehicle as the target driver (first case), and a third party (e.g., substitute driver) other than the default driver operates the target vehicle as the target driver. When the driver wants to drive (the second case), each can be operated in a different way, and the distinction between the first case and the second case can be made, for example, by operating a predetermined function switch installed in the vehicle.

The operation of the control unit 400 in the first case where the basic driver wants to drive the target vehicle as the target driver will be described.

When the basic driver wants to drive the target vehicle as the target driver, the control unit 400 compares the physical information of the basic driver currently detected through the body information detection unit 100 with the pre-stored physical reference information of the basic driver to find a match. In this case, driving privileges can be granted to the primary driver.

Specifically, the basic driver's weight information and face information may be pre-stored in the control unit 400 as the body reference information, and accordingly, the basic driver's weight information and face information currently detected through the body information detection unit 100 If the information matches the weight information and face information stored as body reference information, the control unit 400 may determine that the basic driver has been properly identified and grant driving authority as the target driver.

After driving authority is granted to the basic driver, the control unit 400 determines whether the measurement subject (which may be the basic driver or a person other than the basic driver) is not intoxicated based on the measurement results of the breathalyzer unit 200. If it is determined that it is, the driving function of the target vehicle can be activated.

Specifically, if, as a result of the measurement by the breathalyzer 200, the alcohol concentration is below a predefined standard, the control unit 400 turns on the ignition of the target vehicle by manipulating the ignition button to activate the driving function of the target vehicle. . The above reference value may be predefined in the control unit 400 as the legal alcohol concentration, which is the standard for determining drunk driving, or a value of '0%'. The operation of the control unit 400 to activate the driving function of the target vehicle according to the measurement result of the breathalyzer 200 may follow the operation of a conventional drunk driving prevention system.

In the process of driving the target vehicle as the driving function of the target vehicle is activated, the control unit 400 detects a discrepancy between the current driver of the target vehicle and the measurement subject based on the driving information detected by the driving information detection unit 300. Fraud can be detected. In other words, in this embodiment, cheating may be defined as the difference between the subject of alcohol status measurement through the breathalyzer 200 and the current driver who is currently driving the target vehicle after the driving function of the target vehicle is activated. .

At this time, the control unit 400 determines that the driving information detected by the driving information detection unit 300 during the driving process of the target vehicle is based on the driving pattern of the basic driver that is secured in advance based on the basic driver's past driving history for the target vehicle. If it deviates, it can be determined that fraud has been detected. As described above, driving information may include vehicle speed, acceleration, and the distance between the target vehicle and the preceding vehicle.

To describe the basic driver's driving pattern in detail, as described above, the basic driver may correspond to the owner of the target vehicle. Accordingly, the control unit 400 can acquire and store driving information while the basic driver normally drives the target vehicle, and the driving pattern (i.e., driving pattern) of the basic driver from the past driving history of the basic driver accumulated in this way. tendencies or driving habits) can be acquired. In other words, the control unit 400 generates the driving pattern of the basic driver by applying a machine learning algorithm to the vehicle speed, acceleration, and distance between vehicles obtained while the basic driver normally drives the target vehicle, and then detects cheating. It may be stored in advance as a reference for detection.

The control unit 400 may determine whether the driving information currently detected by the driving information detector 300 deviates from the driving pattern secured in the above manner during the driving process of the target vehicle. In this case, the control unit 400, for example, inputs the currently detected driving information and the pre-stored driving pattern into a similarity analysis algorithm predefined by the designer, and if the similarity value output therefrom is below the standard value, the currently detected driving pattern is It can be judged that the information deviates from the previously secured driving pattern.

If the driving information currently detected by the driving information detection unit 300 deviates from the driving pattern of the basic driver that is secured in advance, i) the basic driver who is not drunk performs a breathalyzer test through the breathalyzer 200 and After the driving function of the target vehicle is activated, a person in a drunken state is currently driving the target vehicle, or ii) a person who is not drunk performs a breathalyzer test through the breathalyzer 200 and drives the target vehicle. After the function is activated, it may be determined that the default driver in a drunken state is currently driving the target vehicle, so in this case, the control unit 400 may determine that an illegal act has been detected.

If it is determined that misconduct has been detected through the above-described process, the control unit 400 may restrict the driving function of the target vehicle. In this case, after outputting a warning through a display device or speaker device mounted on the vehicle, If the current driver ignores the warning and continues to drive the target vehicle, the target vehicle's speed can be limited to a predefined minimum speed to induce the target vehicle to stop and prevent a major accident. In addition to limiting the driving function of the target vehicle, the control unit 400 may request a re-measurement of the drunkenness state by the breathalyzer 200.

Next, the operation of the control unit 400 in the second case where a third party other than the default driver wishes to drive the target vehicle as the target driver will be described. The second case may correspond, for example, to a case where the primary driver, who is the owner of the vehicle, requests a third party, who is a substitute driver, to drive for him or her.

If a third party other than the basic driver wishes to drive the target vehicle as the target driver, the control unit 400 uses one or more of the basic driver's physical information and the third party's driving history information to determine the current status of the target vehicle. Driving authority can be granted to a third party only for the targeted driving (e.g., the route from the current location to the entered destination).

Specifically, unlike the first case, in the second case, since the body reference information of a third party is not secured, the control unit 400 stores the body information of the basic driver currently detected by the body information detection unit 100 in advance. By comparing the body reference information and determining whether it matches (same method as in the first case), driving authority can be granted to a third party through an indirect method of verifying that the default driver currently exists in the target vehicle. . In addition, if the basic driver has a history of requesting a third party to serve as a surrogate driver in the past, the control unit 400 provides information on the third party's driving history of the target vehicle (e.g., information received from the surrogate driving service providing server, You can also grant driving authority to a third party by checking the basic driver's proxy driving request history information for the third party. In this case, in the process of granting driving permission to a third party, the basic driver's physical information is essentially used, and the third party's target vehicle driving history information is selectively used depending on its presence or absence.

After driving permission is granted to a third party, the control unit 400 determines whether the measurement subject (which may be a third party or a person other than a third party) is in a drunken state based on the measurement results of the breathalyzer 200. If it is determined not to be the case, the driving function of the target vehicle can be activated. Since this is done in the same way as the first case, redundant description is omitted.

In the process of driving the target vehicle as the driving function of the target vehicle is activated, the control unit 400 detects a discrepancy between the current driver of the target vehicle and the measurement subject based on the body information detected by the body information detection unit 100. Fraud can be detected. That is, in the second case where the target driver is a third party, the driving pattern of the basic driver cannot be used, so the body information detected by the body information detector 100 is used as information for detecting misconduct.

At this time, if a change in the body information detected by the body information detection unit 100 is detected during the driving process of the target vehicle, the control unit 400 may determine that an illegal act has been detected. That is, when a change in the weight information and face information detected by the body information detection unit 100 is detected during the driving process of the target vehicle, the driver is replaced (e.g., when the driver is replaced by the default driver during the process of proxy driving) ) can be determined to have occurred, so in this case, the control unit 400 can determine that fraud has been detected.

If it is determined that misconduct has been detected through the above-described process, the control unit 400 may restrict the driving function of the target vehicle in the same manner as described in the first case.

In Example 1 described above, it was assumed that the basic driver was the owner of the target vehicle (i.e., the target vehicle was the basic driver's personal car), and this configuration of Example 1 was applied to the 'Car Sharing service'. It may be expanded to cases where this is possible. Example 2 is an embodiment in which the target vehicle is a shared vehicle provided by a car sharing service company, and the basic driver pre-registered in the target vehicle is a reserved driver who has reserved the use of the shared vehicle, which will be described in detail below. .

First, the control unit 400 compares the physical information of the basic driver currently detected through the physical information detection unit 100 with the physical information of the basic driver registered at the time of reservation of the shared vehicle, and if they match, grants driving permission to the basic driver. can do.

Specifically, the basic driver's weight information and facial information (e.g., facial image) may be input from the basic driver when reserving a shared vehicle and stored in advance on the car sharing service providing server, and accordingly, the body information detection unit 100 If the weight information and face information of the basic driver currently detected through match the weight information and face information of the basic driver received from the car sharing service providing server, the control unit 400 determines whether the current basic driver is using the shared vehicle. Driving privileges can be granted to the default driver by determining that he or she corresponds to the actual reserved driver.

After driving authority is granted to the basic driver, the control unit 400 determines whether the measurement subject (which may be the basic driver or a person other than the basic driver) is not intoxicated based on the measurement results of the breathalyzer unit 200. If it is determined that it is, the driving function of the target vehicle can be activated. Since this is done in the same way as Example 1, redundant description is omitted.

In the process of driving the target vehicle as the driving function of the target vehicle is activated, the control unit 400 detects a discrepancy between the current driver of the target vehicle and the measurement subject based on the driving information detected by the driving information detection unit 300. Fraud can be detected. At this time, the control unit 400 receives the basic driver's driving pattern, which is secured in advance based on the basic driver's past driving history for the vehicle owned by the basic driver, from the outside, and uses the driving information detection unit 300 during the driving process of the target vehicle. If the driving information detected by deviates from the received driving pattern, it may be determined that misconduct has been detected.

That is, if the basic driver owns his or her own vehicle (if the basic driver owns a private car), the driving pattern of the basic driver for the owned vehicle can be obtained in the manner described in Example 1, and the obtained With the driving pattern secured in advance on a separate external server, the control unit 400 receives the basic driver's driving pattern from the external server, and the driving information detected by the driving information detector 300 during the driving process of the target vehicle is If there is a deviation from the received driving pattern, it may be determined that misconduct has been detected (same as the first case of Example 1).

Meanwhile, there may be cases where the basic driver does not own a vehicle, and in this case, there is no driving pattern of the basic driver that serves as a reference for determining misconduct. Therefore, if the basic driver does not own a vehicle, the control unit 400 If a change in body information detected by the body information detection unit 100 is detected during the driving process of the target vehicle, it may be determined that an illegal act has been detected (same as the second case of Example 1).

If it is determined that misconduct has been detected through the above-described process, the control unit 400 may restrict the driving function of the target vehicle in the same manner as described in Embodiment 1.

This embodiment described above may be implemented as an operation method of a vehicle drunk driving prevention device as shown in FIG. 2. As shown in FIG. 2, in the operating method of the vehicle drunk driving prevention device of this embodiment, the control unit 400 uses the basic driver's body information detected in advance through the body information detection unit 100 and registered in advance in the target vehicle. Step S100 of granting driving authority to the target driver who currently wishes to drive the target vehicle, and if the control unit 400 determines that the measurement subject is not in a drunk state based on the measurement results of the breathalyzer 200, the target vehicle Step S200 of activating the driving function of the target vehicle, and the control unit 400 based on the driving information detected by the driving information detection unit 300 or the body information detected by the body information detection unit 100 during the driving process of the target vehicle. Thus, to include a step S300 of detecting an illegal act that causes a discrepancy between the current driver of the target vehicle and the measurement subject, and a step S400 of restricting the driving function of the target vehicle when the control unit 400 determines that an illegal act has been detected. It can be implemented. Since the detailed description of each step has been described above, redundant description will be omitted.

In this way, in this embodiment, in addition to measuring the alcohol status of the occupants at the start of driving the vehicle, it continuously monitors and detects misconduct that causes a discrepancy between the breathalyzer test subject and the current driver during the vehicle's driving process. By applying subsequent drunk driving prevention logic that limits the driving function of the vehicle in case of drunk driving, drunk driving can be effectively prevented throughout the entire driving process of the vehicle.

The present invention has been described with reference to the embodiments shown in the drawings, but these are merely illustrative, and those skilled in the art will recognize that various modifications and other equivalent embodiments can be made therefrom.
