Description

  The present invention relates to a drunk driving prevention apparatus that performs various controls by detecting an alcoholic beverage present in a vehicle.

  In recent years, from the viewpoint of safe driving, research on drunk driving prevention devices that determine whether a driver is in a drunk state and permit the vehicle to run only when it is determined that the driver is not in a drunk state has been promoted. ing.

  As a method for determining whether or not the driver is in a drunk state, for example, an inspection device having an exhalation breathing port is arranged near the driver's seat so that the driver breathes in when the vehicle starts. It is conceivable to make a determination by comparing the concentration of an indicator component such as alcohol or acetaldehyde contained in exhaled breath with a determination threshold value.

In addition, in light of the fact that there are people who are resistant to breathing by putting a mouth in the breath-inlet, research is also progressing on technology for determining alcohol, acetaldehyde, etc. contained in the air in the passenger compartment. It has been. According to such a technique, it is possible to perform determination and control for preventing drunk driving even while the vehicle is running. As an example of such a technique, an invention relating to a danger prevention device in which a sensor such as an anthracene sensor for detecting alcohol vapor is installed in the vicinity of a driver's seat is disclosed (for example, see Patent Document 1).

<First embodiment>
The drunk driving prevention apparatus 1 according to the first embodiment of the present invention will be described below. The drunk driving prevention apparatus 1 of this embodiment creates a trace map that traces the position of an alcoholic beverage recognized by an RFID reader, and monitors the drunk behavior of the driver by monitoring this trace map. .

  FIG. 1 is a diagram illustrating an example of the overall configuration of the drunk driving prevention device 1. The drunk driving prevention device 1 has, as a main configuration, RFID (Radio Frequency IDentification) readers 10A, 10B, 10C, 10D, 10E, 10F, and 10G disposed at a plurality of locations in the vehicle interior (the number of these is However, the control device 20 and the drunk driving suppression device 30 are provided.

  Each RFID reader operates in accordance with an instruction signal from the control device 30, and holds the RFID tag by performing short-range wireless communication with an RFID tag provided in a container for alcoholic beverages present in the passenger compartment. Get individual identification information. The RFID tag is, for example, a passive type tag, and operates by using radio waves from each RFID reader as an energy source (each RFID reader may be compatible with an active type tag). As an energy transmission method from each RFID reader to an RFID tag, there are an electromagnetic induction method for transmitting energy and signals by magnetic flux coupling, and a radio wave method for transmitting energy and signals by electromagnetic waves. The individual identification information is, for example, a product code expressed by a predetermined standard, and includes information that can discriminate between alcoholic beverages and non-alcoholic beverages. Further, the content, alcohol content, type, and the like may be included.

  FIG. 2 is a diagram illustrating an arrangement position of each RFID reader. As shown in the figure, each RFID reader is disposed so as to surround the driver. For example, the RFID reader 10A is located at the upper part of the right front door body, the RFID reader 10B is located at the upper part of the left front door body, and the RFID reader 10C is At the rear right end of the vehicle ceiling, the RFID reader 10D is at the rear center of the vehicle ceiling, the RFID reader 10E is at the rear left end of the vehicle ceiling, and the RFID reader 10F is near the drink folder for the driver, The RFID reader 10G is disposed in the vicinity of the drink folder for the passenger on the passenger seat. Note that such an arrangement example is merely an example, and a specific aspect of the present invention is not limited to this.

  The control device 20 is, for example, a computer in which a ROM (Read Only Memory), a RAM (Random Access Memory), and the like are connected to each other via a bus with a central processing unit (CPU) as the center, and an HDD (Hard Disc). Drive, DVD (Digital Versatile Disk) drive, CD (Compact Disc) drive, storage device 22 such as flash memory, I / O port, timer, counter and the like. The ROM stores programs and data executed by the CPU. In addition, the control device 20 includes an RFID control unit 24, a position estimation unit 25, a trace map creation unit 26, and drunk driving suppression as main functional blocks that function when the CPU executes a program stored in the ROM. And a control unit 27. Note that these functional blocks do not necessarily have to be based on another program, and a plurality of parts for realizing each functional block may be included in the same program.

  The RFID control unit 24 periodically operates each RFID reader. Also, the individual identification information read by each RFID reader is input together with the received wave intensity and the like.

The position estimation unit 25 refers to the information input to the RFID control unit 24 and estimates the position of the alcoholic beverage in the vehicle compartment. Specifically, for example, based on the intensity of the received wave received by each RFID reader from the RFID tag provided in the same alcoholic beverage container, the distances D _A and D of the alcoholic beverage from each RFID reader. _{B 1} ,... _DK are calculated, and a plurality of virtual spheres (virtual circles if they are on the same plane) having a radius D _n calculated around each RFID reader in the virtual space imitating the vehicle interior space. The points where the virtual spheres intersect are estimated as the position of the alcoholic beverage. FIG. 3 is an explanatory diagram for explaining the principle. In the figure, for the sake of simplicity, it is assumed that each RFID reader and the alcoholic beverage are on the same plane.

  The trace map creation unit 26 refers to the information input to the RFID control unit 24, and stores a trace map in which the position of the alcoholic beverage in the vehicle interior is associated with the time when the alcoholic beverage is present in the vehicle interior. Created in 22 predetermined areas. The trace map is a map in which the concept of time is added to the position of the alcoholic beverage. For example, it may be position data of alcoholic beverages associated with time, or when periodically scanning the position of alcoholic beverages, it may be a map such as a histogram in which the number of times scanned for each position is accumulated. May be. The trace map may be created as three-dimensional data, or may be created as virtual two-dimensional data viewed from above. FIG. 4 is an example of a trace map created by the trace map creation unit 26. As shown in the figure, it is possible to find a location where the locus of the position of the alcoholic beverage is concentrated on the trace map, and to estimate that the alcoholic beverage is held or drunk at that location.

  The drunk driving suppression control unit 27 refers to the information input to the RFID control unit 24 and the trace map created by the trace map creation unit 26, and instructs the drunk driving suppression device 30 to suppress various drunk drivings. Control.

  The drunk driving suppression device 30 is, for example, a speaker, a buzzer, and a display device for performing warnings and warnings, travel restriction (restricting to a low vehicle speed or restricting the shift position to 1st speed), or travel prohibition. A computer for controlling the engine, a brake device, a transmission, and a communication device for reporting to the outside of the vehicle (the police, etc.) about drunk driving.

  FIG. 5 is a flowchart showing a characteristic processing flow executed by the control device 20 according to the first embodiment, and is a processing flow in which the functions of the functional blocks described above are combined. This flow is repeatedly executed with a predetermined cycle, for example.

  First, with reference to the information input to the RFID control unit 24, it is determined whether or not an alcoholic beverage exists in the vehicle interior (S100). When it is determined that there is no alcoholic beverage in the passenger compartment, one routine of this flow is terminated without performing any processing.

  If it is determined that there is an alcoholic beverage in the passenger compartment, a warning is given using a speaker or the like (first drunk driving suppression control; S102). Specifically, a message is output so as not to drink while driving.

  Then, creation of the trace map is started (S104).

  When the creation of the trace map is started, it is determined whether or not the locus of the position of the alcoholic beverage is concentrated near the driver's seat on the trace map (S106). Here, the location locus is concentrated in the vicinity of the driver's seat means that the alcoholic beverage stays long in the vicinity of the driver's seat (predetermined predetermined area is defined in advance). Therefore, when the trace map is the position data of the alcoholic beverage associated with the time, the accumulated stay time in the vicinity of the driver's seat is obtained, and the determination is made based on whether or not this exceeds a predetermined value. Further, when the trace map is in the form of a histogram, the determination is made based on whether or not the total number of times of scanning at a position near the driver's seat exceeds a predetermined value.

  This determination is made when the alcoholic beverage is placed in a cup folder, etc., or when the driver holds and drinks the alcoholic beverage in his / her hand, and the alcoholic beverage stays longer and the alcoholic beverage is moving In some cases, the characteristic is that the residence time of the alcoholic beverage is shortened. Therefore, by this determination, the device can grasp the behavior that the driver is drinking an alcoholic beverage.

  If it is determined that the locus of the position of the alcoholic beverage is not concentrated near the driver's seat, the trace map is continuously created and the determination of S106 is repeated.

  On the other hand, if it is determined that the locus of alcoholic beverages is concentrated near the driver's seat, it is determined that the driver is or is about to drink alcoholic beverages, and a warning is given using a speaker or the like. At the same time, travel restriction, travel prohibition, notification to the outside of the vehicle, etc. are performed as necessary (second drunk driving suppression control; S108). Since the second drunk driving suppression control is performed after it is estimated that the driver is taking or is about to drink based on the trace map, the second drunk driving suppression control is compared with the first drunk driving suppression control. Therefore, it is appropriate to have a large deterrence.

  According to such a configuration and processing, it is estimated whether or not the driver is taking or is taking a drinking action based on the trace map, and based on this, control such as warning or prohibition of driving is performed at an appropriate timing. Can do. That is, the driver's drinking behavior can be monitored and control for preventing drunk driving can be performed.

<Second embodiment>
Hereinafter, the drunk driving prevention apparatus 2 according to the second embodiment of the present invention will be described. The drunk driving prevention apparatus 2 of the present embodiment monitors the drunk behavior of the driver by a simpler process than that of the first embodiment, and the drunk behavior of the driver by the received wave intensity of the RFID reader surrounding the driver. Is to monitor.

  FIG. 6 is a diagram illustrating an example of the overall configuration of the drunk driving prevention device 2. As shown in the figure, the drunk driving prevention device 2 is common to the drunk driving prevention device 1 of the first embodiment in the hardware configuration, and has a configuration in which the trace map creating unit 26 is omitted from the functional block of the control device 20. Therefore, the same components are denoted by the same reference numerals and description thereof is omitted.

  FIG. 7 is a flowchart illustrating a flow of characteristic processing executed by the control device 20 according to the second embodiment. This flow is repeatedly executed with a predetermined cycle, for example.

  First, with reference to the information input to the RFID control unit 24, it is determined whether or not an alcoholic beverage is present in the passenger compartment (S200). When it is determined that there is no alcoholic beverage in the passenger compartment, one routine of this flow is terminated without performing any processing.

  If it is determined that there is an alcoholic beverage in the passenger compartment, alerting is performed using a speaker or the like (first drunk driving suppression control; S202). Specifically, a message is output so as not to drink while driving.

  Then, it is determined whether or not the average value of the received wave intensity in a plurality of (for example, three) RFID readers (10A, 10C, 10F in the arrangement example of FIG. 2) surrounding the driver's seat is a certain value or more. (S204).

  If it is determined that the average value of the received wave intensity in the plurality of RFID readers surrounding the driver's seat is less than a certain value, the determination in S204 is repeated.

  On the other hand, if it is determined that the average value of the received wave intensity in the plurality of RFID readers surrounding the driver's seat is a certain value or more, it is confirmed that alcoholic beverages are present near the driver's seat. It is determined that the person is or is about to drink alcoholic beverages, and a warning is given using a speaker, etc., and travel restriction, prohibition of travel, reporting to the outside of the vehicle, etc. are performed as necessary (second drinking Operation suppression control; S206). This second drunk driving suppression control is performed after confirming that the alcoholic beverage is present near the driver's seat and estimating that the driver is taking drunk behavior. It is appropriate to have a greater deterrent than the drunk driving suppression control.

  According to such a configuration and processing, the driver is taking a drinking action by confirming whether or not an alcoholic beverage is present at a position close to the driver's seat based on the received wave intensity of the RFID reader surrounding the driver's seat. In addition, it is possible to estimate whether or not the vehicle is going to be taken, and to perform control such as warning or prohibition of traveling at an appropriate timing based on this. That is, the driver's drinking behavior can be monitored and control for preventing drunk driving can be performed.

<Third embodiment>
The drunk driving prevention apparatus 3 according to the third embodiment of the present invention will be described below. The drunk driving prevention apparatus 3 of the present embodiment monitors the drunk behavior of the driver by analyzing an infrared image obtained by imaging the driver in addition to the output of the RFID reader.

  FIG. 8 is a diagram illustrating an example of the overall configuration of the drunk driving prevention device 3. As shown in the figure, the drunk driving prevention device 3 includes a far infrared camera 40 in addition to the hardware configuration of the drunk driving prevention device 1 of the first embodiment. The control device 20 further includes an image analysis unit 28 as a functional block. In the present embodiment, the trace map creation unit 26 may or may not be present.

  The far-infrared camera 40 is a camera having, for example, an infrared filter for shutting out visible light, and outputs the intensity of the far-infrared incident on each image sensor to the control device 20 as temperature data.

  The image analysis unit 28 generates an infrared image indicating the temperature distribution of the subject from the temperature data input from the far-infrared camera 40, and further recognizes the position of the driver's face as the subject and the position of the hand. As for specific methods in such image analysis, since various documents are already known, description thereof will be omitted.

  FIG. 9 is a flowchart showing a flow of characteristic processing executed by the control device 20 according to the third embodiment. This flow is repeatedly executed with a predetermined cycle, for example.

  First, with reference to the information input to the RFID control unit 24, it is determined whether or not an alcoholic beverage exists in the vehicle interior (S300). When it is determined that there is no alcoholic beverage in the passenger compartment, one routine of this flow is terminated without performing any processing.

  If it is determined that there is an alcoholic beverage in the passenger compartment, an alert is made using a speaker or the like (first drunk driving suppression control; S302). Specifically, a message is output so as not to drink while driving.

  Then, monitoring of the driver by the far infrared camera 40 is started (S304).

  Subsequently, the captured image of the far-infrared camera 40 is analyzed to recognize the position of the driver's face and the position of the hand (S306), and near the position of the driver's face or the position of the hand (for example, within a predetermined distance). Then, it is determined whether or not there is an image region having a temperature difference between the face and the hand and a predetermined temperature (S308).

  If it is determined that there is an image area where the temperature difference is equal to or higher than the predetermined temperature, it is estimated that alcoholic beverages are present near the driver's face or hands, so the driver is drinking or trying to drink alcoholic beverages. And a warning using a speaker or the like, and travel restriction or travel prohibition, reporting to the outside of the vehicle, etc. as necessary (second drunk driving suppression control; S310). It is appropriate that the second drunk driving suppression control has a greater deterrence than the first drunk driving suppression control. Note that FIG. 10 is the same situation as the image (FIG. 10B) in the case where there is an image region in which the temperature difference from the face or hand is greater than or equal to a predetermined temperature near the position of the driver's face or hand. FIG. 10 illustrates a normal image (FIG. 10A).

  On the other hand, when it is determined that there is no image region having a temperature difference equal to or higher than the predetermined temperature, the processing in S306 and subsequent steps may be repeatedly executed. However, the driver is further improved by the method described in the first and second embodiments. You may monitor your drinking behavior. That is, it is determined whether or not the locus of the alcoholic beverage position is concentrated in the vicinity of the driver's seat on the previously created trace map (S312), and the locus of the alcoholic beverage position in the vicinity of the driver's seat on the trace map is determined. When it is determined that the concentration is concentrated, the second drunk driving suppression control may be performed (S310), or the received wave intensity in a plurality of RFID readers surrounding the driver's seat is above a certain fixed value on average. It is determined whether or not there is (S314), and if it is determined that the received wave intensity in the plurality of RFID readers surrounding the driver's seat is on average above a certain value, the second drunk driving suppression control is performed ( S310).

  According to the configuration and processing, the driver holds the alcoholic beverage by hand by determining whether or not there is a region where the temperature difference between the face and the hand is a predetermined temperature or more in the infrared image obtained by imaging the driver. It is possible to estimate whether or not a person is drinking, and thus whether or not he / she is drinking, and based on this, control such as warning and prohibition of driving can be performed at an appropriate timing. That is, the driver's drinking behavior can be monitored and control for preventing drunk driving can be performed.

<Fourth embodiment>
Hereinafter, a drunk driving prevention apparatus 4 according to a fourth embodiment of the present invention will be described. The drunk driving prevention device 4 of the present embodiment monitors the drunk behavior of the driver by monitoring the output of the load sensor attached to the cup folder of the driver's seat (and the passenger seat) in addition to the output of the RFID reader. Is.

  FIG. 11 is a diagram illustrating an example of the overall configuration of the drunk driving prevention device 4. As shown in the drawing, the drunk driving prevention device 4 includes load sensors 50A and 50B attached to the drink folders for the driver seat and the passenger seat in addition to the hardware configuration of the drunk driving prevention device 1 of the first embodiment. Provided (may be attached only to the driver's drink folder). In the present embodiment, the trace map creation unit 26 is not an essential configuration.

  The load sensors 50A and 50B are pressure sensors attached to the bottom of the drink folder, for example, and output the measured load to the control device 20 as needed.

  FIG. 12 is a flowchart illustrating a flow of characteristic processing executed by the control device 20 according to the fourth embodiment. This flow is repeatedly executed with a predetermined cycle, for example.

  First, the information input to the RFID control unit 24 is referred to determine whether or not there is an alcoholic beverage in the passenger compartment (S400). When it is determined that there is no alcoholic beverage in the passenger compartment, one routine of this flow is terminated without performing any processing.

  If it is determined that there is an alcoholic beverage in the passenger compartment, a warning is given using a speaker or the like (first drunk driving suppression control; S402). Specifically, a message is output so as not to drink while driving.

  Then, one (or both) of the received wave intensity of the RFID readers 10F and 10G disposed in the vicinity of the drink folder for the driver's seat and the drink folder for the passenger seat is equal to or higher than a predetermined intensity, and the load sensors 50A and 50B. It is determined whether or not a load that is not zero (or less than a predetermined value) is detected (S404). In the case where the load sensor is attached only to the drink folder for the driver's seat, this determination is replaced with “whether the load sensor detects a load that is not zero (or less than a predetermined value)”. If a negative determination is obtained in this step, the determination of this step is repeatedly executed.

  If an affirmative determination is obtained in S404, the outputs of the load sensors 50A and 50B are stored in the RAM or register of the control device 20 (S406).

  Then, the outputs of the load sensors 50A and 50B are monitored at predetermined time intervals, and whether or not a change has occurred compared to the output stored in the RAM or the register (whether or not a change of a predetermined weight or more has occurred). (S408, S410).

  If there is a change in the output of the load sensors 50A and 50B, the amount of alcoholic beverage placed in the cup folder has decreased, so it is determined that the driver has drunk alcoholic beverage and a warning is given using a speaker or the like. If necessary, travel restriction, travel prohibition, notification outside the vehicle, and the like are performed (second drunk driving suppression control; S412). It is appropriate that the second drunk driving suppression control has a greater deterrence than the first drunk driving suppression control.

  According to such a configuration and processing, it is detected that the amount of alcoholic beverage has decreased due to a change in the output of the load sensor attached to the cup holder, and it is estimated that the driver has drunk alcoholic beverage. Based on this, it is possible to perform control such as warning and travel prohibition at an appropriate timing. That is, the driver's drinking behavior can be monitored and control for preventing drunk driving can be performed.

  The best mode for carrying out the present invention has been described above with reference to the embodiments. However, the present invention is not limited to these embodiments, and various modifications can be made without departing from the scope of the present invention. And substitutions can be added.

  For example, also in the fourth embodiment, when the output value of the load sensor does not change, the driver's drinking behavior may be further monitored by the method described in the first embodiment or the second embodiment. Further, the technique of the third embodiment and the technique of the fourth embodiment may be combined.

  Moreover, although the RFID reader was illustrated as a specific example of the apparatus which reads the individual identification information of alcoholic beverage, it is not limited to what is by radio | wireless communication, for example, image | photographs barcode etc., and individual identification information of alcoholic beverage is obtained by image recognition. It may be read.
