Description

Drunk driving prevention system and display control method of the drunk driving prevention system {SYSTEM FOR PREVENTING DRUNK DRIVING AND METHOD FOR CONTROLLING POP-UP DISPLAY IN THE SAME}

The present invention relates to a drunk driving prevention system and a display control method of the drunk driving prevention system, and more particularly, to a technology for providing a guide display for the drunk driving prevention system.

In order to fundamentally prevent drunk driving, attempts have been made to adopt a system for preventing drunk driving in a vehicle.

In this regard, Korean Registered Patent No. 10-1705968 discloses that when a driver makes contact with a breathalyzer, the driver's drinking state is checked using the measured biometric information, and the shift lever of the vehicle is unlocked only when the driver is not drinking. There is a technology to prevent drunk driving.

In addition, Japanese Unexamined Patent Publication No. 2005-096663 discloses a technique for preventing drunk driving by determining whether or not the driver has been drinking by using the driver's breath, and shutting off electricity for starting when it is determined that the driver is drunk.

In addition, Japanese Patent Registration No. 5348457 includes a camera and an alcohol detection device for photographing the driver, and an interlock device that prohibits starting of the engine when alcohol is detected in the driver's exhaled air by the alcohol detection device. The driver monitoring device is disclosed. In particular, in Japanese Patent Registration No. 5348457, the engine is started only in an authentication situation in which the driver has not changed by reflecting the result of taking multiple shots by the camera at different timings immediately before and after the alcohol detection operation by the alcohol detection device. A device implemented to make this possible is disclosed.

On the other hand, it is extremely rare that the drunk driving prevention system installed in the vehicle is actually used. However, since the drunk driving prevention system is activated every time the vehicle is boarded, the driver has to wait for unnecessary time due to related notifications. This can occur, which is a major obstacle to commercializing a drunk driving prevention system.

However, even in the narrow system, configurations such as a camera and a storage unit are not excluded, and the system may be implemented in a form in which the camera, storage unit, display unit, control module, and sensor module provided in the vehicle system are interlocked.

According to a preferred embodiment of the present invention, the sensor module 100 can inhale the driver's breath and detect the respiratory volume and the alcohol concentration contained in the driver's exhalation. To this end, the sensor module 100 may include a suction unit 110 for inhaling the driver's exhaled air and a sensor unit 120 including an alcohol detection sensor for detecting alcohol contained in the driver's exhaled air.

The intake unit 110 may be installed at a position where the driver's exhaled breath can be easily absorbed near the driver's seat, and may be preferably installed near the cluster, steering wheel, or center fascia.

In particular, a fan driven by a motor may be installed in the suction unit 110 of the sensor module 100, and the amount of air intake may be increased or decreased by controlling the number of revolutions of the fan. The fan is installed in the inlet of the suction part 110, and the motor for driving the fan may be operated by a control unit of the sensor module 100 itself or a sensor control unit 240 within the control module 200. .

In addition, the sensor unit 120 is configured to detect the amount of breath inhaled through the suction unit 110 and to detect the alcohol component included in the inhaled air. In this regard, the sensor unit may include a carbon dioxide sensor for measuring a breathing volume, and may include an ethanol sensor to detect an alcohol concentration in the driver's exhalation. In addition, an optical sensor capable of optically detecting an alcohol component in breath may be applied to the sensor module.

The carbon dioxide sensor is capable of measuring the amount of carbon dioxide contained in the breath of the measurer. Through this carbon dioxide sensor, the driver's breathing volume is detected, and based on this, whether the driver's breathing volume is sufficiently supplied to have reliability in detecting the alcohol concentration. You can check.

Information on the detected respiratory volume and information on the alcohol component may be transmitted to the control module 200 side. Accordingly, in the control module 200, it is possible to compare the measured respiratory volume information and the alcohol concentration information with a preset reference concentration to determine whether the driver is drunk or not and whether the driver can drive.

The system for preventing drunk driving according to a preferred embodiment of the present invention may include a display unit for displaying various types of information, and the display unit 400 may be a vehicle display device existing within a driver's viewing angle range, for example It may be a display of a vehicle cluster or a display of an AVN (Audio, Vedio, Navigation) system, and may include a separate display.

For example, when the display unit is a large screen cluster, the screen of the cluster can be divided into three parts into the center, left, and right parts, so that breathing authentication guide information and the like are output within a preset area within the divided screen.

In addition, when the display unit is an AVN system, the display unit may be divided into left and right sides to display respiration certification guidance information on the left side close to the driver or displayed on the entire screen.

The display unit 400 may be configured to transmit various types of information required to be notified to the driver during the operation of the drunk driving prevention system, and in particular, may be configured to display guidance information related to a breathing authentication procedure.

For example, the display unit 400 may transmit a message related to specific information such as respiration authentication completion, re-authentication request, and abnormal authentication reason when respiration authentication is initiated.

The drunk driving prevention system according to the present invention may include a storage unit 500 . The storage unit 500 may store various types of information, such as a breathing authentication procedure, image information photographed by the related camera 300 and alcohol detection information detected by the sensor module 100 . Such image information may include information such as a photographing time and a driver's face.

In addition, the storage unit 500 may be configured to store camera information captured when an abnormality inside the vehicle is detected after the driver gets off. The information stored in the storage unit can be transmitted to the server by the in-vehicle communication module.

In addition, the storage unit 500 may store vehicle information including a window opening/closing state and an air conditioner operating state before respiration authentication starts. In confirming the driver's drinking state, since it is preferable to make the measurement in a circulation mode in which all windows/sunroofs 620 are closed for accurate measurement, in the control module 200, when breathing authentication is initiated, the windows/sunroof of the vehicle ( 620), and control to switch the vehicle to the betting circulation mode. To this end, the vehicle control unit 280 of the control module 200 may be configured to transmit a control command for opening/closing the windows/sunroof 620 of the vehicle or controlling the ventilation/outside air circulation mode of the air conditioner. In addition, the vehicle control unit 280 may perform control to close the vehicle door in order to perform breathing authentication.

At this time, the pre-stored information before breathing authentication refers to information about the surrounding environment set by the driver before checking whether or not he or she has been drinking. Therefore, the control module 200 performs breathing authentication stored in the storage unit 500 after completion of the breathing authentication. The vehicle internal devices 600 may return to the driver's existing settings by controlling the vehicle state to be changed according to previous vehicle information. However, in the case of a vehicle door, since opening control is not possible, it is preferable that the state is not stored in the storage unit 500.

The drunk driving prevention system according to a preferred embodiment of the present invention may further include a biometric authentication unit 700 for authenticating a driver. The biometric authentication unit 700 is for verifying current driver information, and may be configured as a biometric authentication device capable of authenticating driver's fingerprint or iris information.

The storage unit 500 may store the biometric authentication information of a specific driver in advance, and the authentication unit 210 compares the stored biometric authentication information with the current driver's biometric authentication information authenticated through the biometric authentication unit 700 to determine the identity of the driver. It can also be configured to go through an authentication process.

In addition, the control module 200 may be connected to other components in the system, such as the sensor module 100, the camera 300, the display unit 400, and the storage unit 500, by a communication interface, and transfer from these components It is configured to control the overall system according to the received information.

The control module 200 may include an authentication unit 210, a determination unit 220, an image processing unit 230, a sensor control unit 240, and a vehicle control unit 250. Each component included in the control module 200 is classified according to the function performed by the control module 200, and it does not mean that each component dividing the control module 200 is physically separated. . Among the components of the control module, except for the authentication unit 210, the remaining components, that is, the determination unit 220, the image processing unit 230, the sensor control unit 240, and the vehicle control unit 250, are typical of a drunk driving prevention system. It is a configuration provided as an example to explain the function, and even if some of these configurations are excluded, any form capable of implementing a drunk driving prevention system can be applied as a control module of the present invention. In addition, each component in the control module may be configured to communicate with each other.

The control module 200 in a preferred embodiment of the present invention is a controller capable of performing various functions such as breathing authentication, alcohol determination, and vehicle control, and a processor performing calculations to perform these functions, and a processor It may be configured to include a memory in which an algorithm for performing a function is stored. In addition, the control module 200 may be provided by modularizing the authentication unit 210, the determination unit 220, the sensor control unit 240, and the vehicle control unit 250. In addition, the sub-components of the control module 200 as described above are just examples, and the control module 200 may be configured to perform the same or corresponding functions while communicating with other vehicle controllers. In this case, some sub-components may be excluded or replaced.

Regarding the basic configuration of the control module, the authentication unit 210 is a component that oversees the breathing authentication procedure, and the determination unit 220 compares the alcohol concentration detected by the sensor module 100 with the reference concentration to determine the driver's drinking state. can be diagnosed

The authentication unit may check whether the driver is seated from information provided by a device such as a weight sensor of the driver's seat or a camera 300 that captures the driver's seat, and may identify the driver from an image captured by the camera 300. In addition, the authentication unit 120 may be configured to provide guidance information related to the breathing authentication procedure through the display unit 400 and determine whether or not to complete breathing authentication based on the driver's respiratory volume supplied to the sensor module 100. .

Here, breathing authentication means a procedure in which the driver's breath is inhaled so that the sensor module 100 can detect the alcohol component contained in the driver's exhaled breath, and whether or not drunk is determined according to the alcohol component detected by the sensor module. do. In addition, completion of breath certification means that the concentration of alcohol contained in the driver's exhalation by the control module is within a standard value, and thus breath certification has been completed in a state suitable for driving.

For example, when breath authentication is initiated by the authentication unit 210, the sensor module 100 detects the alcohol component contained in the driver's breath, and information on the detected alcohol component is sent to the control module 200 side. The alcohol concentration detected by the sensor module 100 by the determination unit 220 of the control module 200 is compared with the reference concentration to diagnose the driver's drinking state.

As a result of the comparison, when it is determined that the driver is in a drinking state exceeding the reference concentration, the determination unit 220 determines that the driving is impossible (respiration certification failure) due to the driver drinking, and the vehicle control unit of the control module 200 The starting limiting device 630 may be operated through 250. In this regard, the start limiting device 630 refers to a device that controls the vehicle to be unable to drive by limiting the start of the vehicle, and may be, for example, a device that cuts off the starting power. On the other hand, if the detected driver's alcohol concentration is within the standard concentration, it is determined that the breathing certification is completed because it is in an appropriate state, and the vehicle driving may be controlled.

In addition, the authentication unit controls the display of guide information according to the current system state and the detection result through the display unit in performing a breath authentication procedure related to the alcohol measurement of the drunk driving prevention system.

For example, the authentication unit displays guide information such as 'WAIT', 'READY', 'APPROVED', and 'DISAPPROVED' in relation to the breathing authentication procedure. can be sent through Here, 'WAIT' is a standby state of the sensor module, and means a standby state for hardware initialization and sensor preheating. In addition, 'ready for authentication' means a state in which the driver can authenticate respiration, and indicates a state in which the position of the sensor module is displayed to guide respiration authentication. In addition, 'APPROVED' means that the driver exhaled all the breaths and alcohol components below the standard were detected in the breath, and breath authentication was successful. Indicates a case where breathing authentication fails due to a component being detected. On the other hand, when the driver's respiratory rate is not sufficiently input during breathing authentication, a guidance message for adjusting the driver's breathing position, for example, may be configured to transmit a 'Retry Breathing Authentication (RETRY)' request. All information provided through the drunk driving prevention system, including guidance related to the breathing certification procedure, is collectively referred to as breathalyzer guidance information.

In addition, the authenticator may variably control the display of the breathalyzer test guide information according to the starting state of the vehicle when displaying the drink test guide information.

Basically, a sobriety test must be taken at every start-up request by the driver. However, if the same driver gets into the driver's seat again within a certain period of time, or if there is no intention to drive, it is preferable to avoid pop-up on the display for measuring alcohol for the convenience of the driver. In addition, if normal breathing certification is completed and the vehicle is driving, the breathalyzer test guide information provided by the drunk driving prevention system is unnecessary.

Therefore, in the system for preventing drunk driving according to an exemplary embodiment of the present invention, it is determined whether the driver is the same driver as the recently authenticated driver or whether the person sitting in the driver's seat is a person who has no intention of driving, In this situation, a system for preventing drunk driving that can enhance the convenience of passengers is provided by configuring the system not to display information related to the breathing certification procedure. In addition, according to a preferred embodiment of the present invention, when the vehicle is in a driving state, the breathalyzer test guide information may be configured not to be displayed through the display unit. For example, in a situation in which a vehicle is started to drive after completing breathing authentication in an illegal way for the purpose of avoiding a breathalyzer test, even if the drunk driving prevention system detects such fraudulent authentication, the breathalyzer test guide information is controlled not to be displayed. , it can be controlled to prioritize driving stability. In addition, in this embodiment, even if the drunk driving prevention system continuously operates while driving, the related guide information is controlled not to be displayed while driving.

In this regard, a specific example of selectively providing breathalyzer test guide information through the authentication unit will be described later with reference to FIGS. 2 and 3 .

In addition, the drunk driving prevention system may be configured to include an image processor 230, a sensor controller 240, and a vehicle controller 250.

The image processing unit 230 receives image information captured by the camera 300 and processes it into image information necessary for the control module 200 . The sensor controller 240 is for controlling the sensor module, and can control the rotational speed of the fan of the sensor module 100, the sensitivity of the sensor module 100, and the like. The vehicle control unit 250 transmits control commands for other internal devices 600 in the vehicle, for example, the vehicle door, window/sunroof 620, air conditioner 610, start limiter 630, and the like. can be configured to

A specific example of a method for displaying and controlling the display of alcohol measurement guide information of the system for preventing drunk driving having such a configuration will be described with reference to FIGS. 2 and 3 .

First, FIG. 2 is a flowchart of a display control method using a drunk driving prevention system according to an embodiment of the present invention.

A display control method using a system for preventing drunk driving according to an embodiment of the present invention is configured to receive a driver's starting input and determine whether or not to display sobriety measurement guide information based on the driver's starting input.

Looking at the specific steps, as shown in FIG. 2 , when a driver gets on board (S201), a starting input is received and whether any starting input is input by the driver is checked (S202, 208). For example, as in steps S202 and S208 of FIG. 2 , it may be determined whether the engine is turned on for engine start or the electronic device is turned on for use.

In this regard, when the driver's starting input is a start-on input such as engine start, steps S203 to S207 are executed, and the driver's start input is an electronic device-on input that converts only electronic devices to a use state without engine start. , the step of step S209 is carried out.

Specifically, in the present invention, in determining whether to display the breathalyzer test guide information, whether or not to display the breathalyzer test guide information is determined according to the engine-on state input by the driver. Accordingly, as shown in FIG. 2 , when the driver's start input is a start-on input for vehicle driving, it is determined that the driver has a driving intention (driving possible state after breathing authentication), and it is determined to display the breathalyzer test guide information. Yes (S203, S204). On the other hand, if the driver's starting input is an electronic device on input for an electronic device usable state, it is determined that the driver has no driving intention (electronic device usable state) and it is determined not to display the alcohol test guide information (S209 ).

If the start-on signal is input by the driver, the breathalyzer test guide information is displayed through the display unit (S204). Thereafter, if the breathing certification confirming that the drunk driving prevention system is not in a drunken state is completed, the vehicle is converted to a drivable state (S206). Meanwhile, when the vehicle is driving, the authentication unit may control not to display the breathalyzer test guide information even when displaying the drink test guide information is necessary (S207).

On the other hand, if only the electronic device on signal is input by the driver, the breathalyzer test guide information is set not to be displayed, and it is checked whether the start-on signal is input by the driver again (S210), so that the start-on signal is input. In this case, control is performed to display breathalyzer test guide information by switching to a driving state after breathing authentication.

Meanwhile, in displaying the breathalyzer test guide information through step S204, there may be cases in which other information in the vehicle, for example, guide information such as vehicle air pressure drop, power supply check, etc., should be overlapped and displayed through the display unit.

For example, in a state in which breathalyzer test guide information is being displayed during a breathing authentication procedure, a problem may arise when output of vehicle condition guide information related to internal devices is requested by a vehicle controller. In this regard, in a preferred embodiment of the present invention, the vehicle condition guidance information is classified into safety specification information and convenience specification information, and superiority and inferiority with the sobriety measurement guidance information are set in advance according to the classification of the safety specification information and the convenience specification information. In this way, the output order of the display unit may be differently designated.

For example, guidance information on the driving system, wheels, and power-related facilities, such as air pressure drop, engine system error, power supply check, brake system check, hybrid system check, etc., is information directly related to vehicle safety, so safety specification information It can be classified and handled with priority over breathalyzer test guidance information. On the other hand, guidance information related to user input status, such as system calls for fuel economy and mileage, or display of user setting-related menus as the user selects menus through the control panel, is information not directly related to vehicle safety. Therefore, it is classified as convenience specification information and treated as a subordinate to breathalyzer test guide information.

Therefore, in displaying the vehicle condition guide information transmitted from the vehicle controller, when a display request for safety specification information is made while displaying the breathalyzer test guide information, the display unit stops displaying the breathalyzer test guide information and displays the safety specification information. priority can be displayed. Meanwhile, when a display request for convenience specification information is made while displaying the breathalyzer test guide information, the display unit may display the convenience specification information after the display of the breathalyzer test guide information is finished.

3 is a flowchart illustrating a display control method using a drunk driving prevention system according to another embodiment of the present invention.

Unlike FIG. 2, FIG. 3 is characterized in that it further includes the same driver determination step for respiration certification exemption. That is, according to the embodiment of FIG. 3, if the same driver re-boarded within the reference time (eg, within several minutes), the breathalyzer test guide information for the breath authentication procedure is not displayed again, and the breath authentication procedure It is characterized in that the vehicle is immediately switched to a state in which driving is possible by exempting the vehicle.

Specifically, when the driver gets on board (S301), the vehicle operation ends, and whether or not re-boarding within the standard time is checked (S302). In determining whether the same driver is re-boarding, the order of steps S302 and S303 may be interchanged.

If the driver is not the same or the driver is not re-boarding within the reference time, the same control process according to the starting input state as in FIG. 2 is performed.

That is, in step S304, when it is determined that the driver's start input is the start-on input for driving the vehicle, it is determined that the driver has a driving intention (a driving state after breathing certification), and the breathalyzer measurement guidance information is displayed. It can be determined (S305, S206). On the other hand, when it is determined through step S310 that the driver's start input is an electronic device on input for an electronic device usable state, it is determined that the driver has no driving intention (electronic device usable state) and the breathalyzer test guide information is displayed. It may be decided not to do so (S311).

If the start-on signal is input by the driver, the breathalyzer test guide information is displayed through the display unit (S306). Thereafter, if the breathing certification confirming that the user is not in a drunken state is completed by the drunk driving prevention system (S307), the vehicle is converted to a driving state (S308). Meanwhile, when the vehicle is driving, the authentication unit may control not to display the breathalyzer test guide information even when displaying the drink test guide information is necessary (S309).

On the other hand, if only the electronic device on signal is input by the driver (S310), the breathalyzer test guide information is set to not be displayed (S311), and it is checked whether the start-on signal is input by the driver again (S312), When a start-on signal is input, control is performed to display breathalyzer test guide information by switching to a driving state after breathing authentication.

Meanwhile, in determining whether the driver is the same in step S303, information photographed by a camera may be used. For example, image information photographed by a camera in a breathing authentication procedure during a previous driving may be stored in a storage unit. In addition, when the driver re-boards, the camera re-photographs the driver in the driver's seat, the captured image information is processed by the image processing unit, and then compared with the image information stored in the previous driving to determine whether the driver is the same through the authentication unit. You can check.

If it is confirmed through step S303 that the driver is the same, the authentication unit exempts breathing authentication (S313), and when the driver inputs ignition on (S314), controls not to display the breathalyzer guidance information (S309).

Through the drunk driving prevention system and the display control method of the alcohol measurement guide information as described above, it is possible to reduce driver's discomfort by preventing unnecessary guide information from being displayed.
