[0007] [Figure 1] This is a block diagram showing the configuration of the warning system and warning device. [Figure 2] This is a block diagram showing the functional configuration of the warning device. [Figure 3] This is a flowchart illustrating the processes performed by the warning system and warning device. [Modes for carrying out the invention]

[0008] Exemplary embodiments of this disclosure will be described with reference to the drawings. <First Embodiment> 1. Configuration of Warning System 1 and Warning Device 3 The configuration of warning system 1 and warning device 3 will be explained based on Figures 1 and 2. As shown in Figure 1, warning system 1 comprises warning device 3, server 5, and management device 7. Warning device 3 is mounted on vehicle 9. Server 5 and management device 7 are installed outside vehicle 9. Server 5 is, for example, part of a cloud computer.

[0009] In addition to the warning device 3, vehicle 9 is equipped with an alcohol detection device 11, a camera 13, a reader 15, a warning execution device 17, an external notification device 19, a capacitor 21, and a smartphone 23.

[0010] The alcohol detection device 11 is equipped with a breath blowing nozzle. The driver blows their breath into the breath blowing nozzle. The alcohol detection device 11 detects that breath is being blown in based on the pressure of the breath. When the alcohol detection device 11 detects that breath is being blown in, it detects the alcohol concentration in the breath. The alcohol detection device 11 sends information representing the detected alcohol concentration to the warning device 3.

[0011] Camera 13 takes pictures and generates image data. The field of view of camera 13 can include the alcohol detection device 11 and the driver using the alcohol detection device 11. Camera 13 sends the generated image data to the warning device 3.

[0012] The reader 15 reads the driver's identification information from a medium on which the driver's identification information is stored. Examples of a medium on which the driver's identification information is stored include a driver's license and a My Number card. The reader 15 sends the read identification information to the warning device 3.

[0013] The warning execution device 17 issues a warning to the driver by generating one or more selected from the group consisting of sound, light, vibration, odor, and electrical stimulation. Preferably, the warning execution device 17 generates sound, light, or both.

[0014] Examples of sounds include sounds that are unpleasant to the driver. Examples of sounds include sounds representing words and voices. An example of a sound that the warning device 17 will emit if the driver has not performed an alcohol concentration test is the sound of the words "Do it." An example of a sound that the warning device 17 will emit if the driver has performed an alcohol concentration test and the alcohol concentration exceeds the lower limit is the sound of the words "Stop driving." Examples of voices include the voices of the driver's supervisor or children. The warning device 17 can change the words or voice depending on the driver, for example.

[0015] The external notification device 19 includes an electronic display board, a display, a speaker, etc., installed on the outer surface of the vehicle 9. The external notification device 19 provides notifications to persons outside the vehicle 9 via video, audio, or both. Examples of notification content include video or audio such as "Drunk driving," "Dangerous driving," or "Please contact ~." The capacitor 21 supplies power to the warning device 3 in the event of a loss of normal power supply to the warning device 3.

[0016] The smartphone 23 has a known configuration. An app corresponding to the warning device 3 is installed in the smartphone 23. The smartphone 23 can alternatively perform the communication from the warning device 3 to the server 5.

[0017] The smartphone 23 can read the device information displayed on the surface of the warning device 3. The device information is, for example, a QR code (registered trademark). The smartphone 23 can send the device information and the user information to the server 5. The user information is information for identifying the user of the smartphone 23. The user of the smartphone 23 is, for example, the driver of the vehicle 9.

[0018] The warning device 3 can acquire vehicle information from the vehicle 9. The vehicle information includes information representing the shift of the vehicle 9, information representing the speed of the vehicle 9, information representing the rotational speed of the engine or motor of the vehicle 9, and the like.

[0019] The warning device 3 can receive a GPS signal from the GPS satellite 31. The warning device 3 can calculate the position of the vehicle 9 based on the GPS signal. Further, the warning device 3 can calculate the speed of the vehicle 9 based on the change in the position of the vehicle 9 over a certain period of time.

[0020] The warning device 3 includes a microcomputer having a CPU 33 and a semiconductor memory such as a RAM or a ROM (hereinafter referred to as the memory 35). Each function of the warning device 3 is realized by the CPU 33 executing a program stored in a non-transitory tangible recording medium. In this example, the memory 35 corresponds to the non-transitory tangible recording medium storing the program. Further, when this program is executed, a method corresponding to the program is executed. Note that the warning device 3 may include one microcomputer or a plurality of microcomputers.

[0021] As shown in FIG. 2, the warning device 3 includes an alcohol concentration acquisition unit 41, an identification information acquisition unit 43, an image acquisition unit 45, a speed detection unit 47, a condition satisfaction judgment unit 49, a warning unit 51, an external notification unit 53, a warning stop unit 55, and a notification unit 57.

[0022] The alcohol concentration acquisition unit 41 acquires the alcohol concentration from the alcohol detection device 11. The identification information acquisition unit 43 acquires the driver's identification information from the reader 15. The image acquisition unit 45 acquires image data from the camera 13. The speed detection unit 47 detects the speed of the vehicle 9. The method of detecting the speed is, for example, a method of detecting from the change in the position of the vehicle 9 calculated based on the GPS signal.

[0023] The condition satisfaction judgment unit 49 judges whether all of a plurality of specific conditions are satisfied at the judgment timing. The judgment timing is, for example, (a) the timing when the shift of the vehicle 9 becomes drive, (b) the timing when the speed of the vehicle 9 exceeds the threshold value, or (c) the timing when the reference time has elapsed after the driver of the vehicle 9 gets on the vehicle 9.

[0024] Note that the condition satisfaction judgment unit 49 can acquire the timing when the shift of the vehicle 9 becomes drive from the vehicle information. The condition satisfaction judgment unit 49 can detect the timing when the speed of the vehicle 9 exceeds the threshold value (b) based on the speed of the vehicle 9 detected by the speed detection unit 47. The condition satisfaction judgment unit 49 can detect that the driver of the vehicle 9 has got on the vehicle 9 by using, for example, a load sensor provided on the driver's seat.

[0025] In this embodiment, the multiple specific conditions include: (J1) the alcohol concentration acquired by the alcohol concentration acquisition unit 41 is below the lower limit; (J2) the identification information acquired by the identification information acquisition unit 43 is the identification information of a driver that has been registered in advance; (J3) the image data acquired by the image acquisition unit 45 shows the alcohol detection device 11 and the driver using the alcohol detection device 11; and (J4) the vehicle 9 is stopped. Each of (J1) to (J4) is a single specific condition.

[0026] The condition satisfaction determination unit 49 attempts to recognize the alcohol detection device 11 and the driver by performing known image recognition processing on the image data. Based on the results of the image recognition processing, it determines whether (J3) is satisfied. The condition satisfaction determination unit 49 determines whether (J4) is satisfied based on the speed of the vehicle 9 detected by the speed detection unit 47.

[0027] If the warning unit 51 determines that any of several specific conditions are not met, it will use the warning execution device 17 to issue a warning to the driver. If the external notification unit 53 determines that any of several specific conditions are not met, it will use the external notification device 19 to notify the outside of the vehicle 9.

[0028] The warning stop unit 55 determines whether the warning stop conditions have been met after the warning unit 51 has started issuing a warning. If it determines that the warning stop conditions have been met, it stops the warning. If it determines that the warning stop conditions have not been met, it continues the warning. The warning stop conditions are, for example, (A) the engine or motor of vehicle 9 stops, or (B) vehicle 9 stops.

[0029] The warning stop unit 55 can determine whether (A) has been satisfied based on the vehicle information. The warning stop unit 55 can also determine whether (B) has been satisfied based on the speed of the vehicle 9 detected by the speed detection unit 47.

[0030] If the notification unit 57 determines that any of several specific conditions are not met, it sends a notification to the management device 7 via the server 5. The notification includes, for example, the driver's name, the device information of the warning device 3, the alcohol concentration, whether the vehicle 9 is moving or not, and the location information of the vehicle 9. However, if the driver has not performed an alcohol concentration test, the notification will not include the alcohol concentration, but will include a statement that an alcohol concentration test was not performed.

[0031] Furthermore, the notification unit 57 uses the power supply from the capacitor 21 to notify the management unit 7 if the normal power supply to the warning device 3 is lost. The notification unit 57 also periodically determines whether the warning device 3 or the equipment connected to the warning device 3 has been removed, and if it determines that it has been removed, it notifies the management unit 7. Examples of equipment connected to the warning device 3 include the alcohol detection device 11, camera 13, reader 15, warning execution device 17, and external notification device 19.

[0032] When a notification is received by the management device 7, it sets the communication between the warning device 3 and the management device 7 to a state where telephone or video conferencing is possible.

[0033] 2. Processes performed by warning system 1 and warning device 3 The processes performed by the warning system 1 and warning device 3 will be explained with reference to Figure 3. This process begins when the driver gets into the vehicle 9 and the power to the vehicle 9 is turned on.

[0034] In step 1, the warning device 3 collects information. Specifically, the alcohol concentration acquisition unit 41 acquires the alcohol concentration from the alcohol detection device 11. The identification information acquisition unit 43 acquires the driver's identification information from the reader 15. The image acquisition unit 45 acquires image data from the camera 13. The speed detection unit 47 detects the speed of the vehicle 9.

[0035] In step 2, the condition satisfaction determination unit 49 determines whether the determination timing has been reached. As described above, the determination timing is, for example, (a) when the shift of vehicle 9 is set to drive, (b) when the speed of vehicle 9 exceeds a threshold, or (c) when a reference time has elapsed since the driver of vehicle 9 got into vehicle 9.

[0036] If it is determined that the decision timing has been reached, proceed to step 3. If it is determined that the decision timing has not yet been reached, return to step 1.

[0037] In step 3, the condition satisfaction determination unit 49 determines whether all of the multiple specific conditions are met. As described above, the multiple specific conditions include (J1) the alcohol concentration obtained by the alcohol concentration acquisition unit 41 is below the lower limit, (J2) the identification information obtained by the identification information acquisition unit 43 is the identification information of a registered driver, (J3) the image data obtained by the image acquisition unit 45 shows the alcohol detection device 11 and the driver using the alcohol detection device 11, and (J4) the vehicle 9 is stopped. The determination of whether (J1) to (J4) is satisfied, in whole or in part, may be performed by the warning device 3 or by the server 5. If the server 5 performs the determination of whether (J1) to (J4) is satisfied, the server 5 sends the determination result to the warning device 3.

[0038] If (J1) is not met, it may be because the driver has not yet undergone an alcohol concentration test, or if the alcohol concentration test has been performed and the result exceeds the lower limit. If it is determined that all of the multiple specific conditions are met, this process will be terminated. If it is determined that even one of the multiple specific conditions is not met, proceed to step 4.

[0039] In step 4, the warning unit 51 initiates a warning using the warning execution device 17. The warning continues until it is determined that the warning stop conditions have been met in step 8, which will be described later. The intensity of the warning is initially weak and becomes stronger after a certain period of time. Examples of warning intensity include the intensity of light, the loudness of sound, the magnitude of vibration, the intensity of odor, and the magnitude of electrical stimulation.

[0040] In step 5, the external notification unit 53 starts notification using the external notification device 19. Notification continues until it is determined that the warning stop conditions have been met in step 8, which will be described later.

[0041] In step 6, the notification unit 57 sends a notification to the management device 7 via the server 5. The notification includes, for example, the driver's name, device information of the warning device 3, alcohol concentration, whether the vehicle 9 is moving or not, and the location information of the vehicle 9. However, if the driver has not performed an alcohol concentration test, the notification will not include the alcohol concentration, but will include a statement that an alcohol concentration test has not been performed.

[0042] In step 7, the management device 7 sets the communication between the warning device 3 and the management device 7 to enable telephone or video conferencing.

[0043] In step 8, the warning stop unit 55 determines whether the warning stop conditions have been met. As described above, the warning stop conditions are, for example, (A) the engine or motor of vehicle 9 stops, or (B) vehicle 9 stops.

[0044] If it is determined that the warning stop conditions have been met, proceed to step 9. If it is determined that the warning stop conditions have not been met, return to the step before step 8.

[0045] In step 9, the warning stop unit 55 stops the warning and notification. After step 9, this process ends.

[0046] 3. Effects of Warning System 1 and Warning Device 3 (1A) If even one of the multiple specific conditions is not met, the warning unit 51 issues a warning using the warning execution device 17. At this time, the driver experiences a moderate level of discomfort, so the driver is guided to ensure that all of the multiple specific conditions are met. As a result, it is possible to prevent the driver from continuing to drive the vehicle 9 when even one of the multiple specific conditions is not met.

[0047] In particular, if the driver has not performed an alcohol concentration test, the specific condition (J1) is not met, so the warning unit 51 executes a warning using the warning execution device 17. As a result, it is possible to prevent the driver from continuing to drive the vehicle 9 without performing an alcohol concentration test.

[0048] Furthermore, since the specific conditions include (J2) that the identification information acquired by the identification information acquisition unit 43 is the identification information of a registered driver, and (J3) that the image data acquired by the image acquisition unit 45 shows the alcohol detection device 11 and the driver using the alcohol detection device 11, even if someone other than the driver attempts to detect the alcohol concentration, some of the specific conditions will not be met, and a warning will be issued. As a result, it is possible to suppress people other than the driver from attempting to detect the alcohol concentration.

[0049] (1B) The warning includes one or more selected from the group consisting of sound, light, vibration, odor, and electrical stimulation. This can further enhance the effectiveness of the warning. (1C) If any one of the multiple specific conditions is not met, the external notification unit 53 will issue a notification using the external notification device 19. Persons outside the vehicle 9 will be able to learn from the notification that the state of the vehicle 9 is one in which at least some of the multiple specific conditions are not met.

[0050] The driver is guided to ensure that all of several specific conditions are met in order to prevent the situation from becoming known to outsiders. As a result, it is further reduced the likelihood of the driver continuing to operate vehicle 9 when even one of the several specific conditions is not met.

[0051] (1D) The warning stop unit 55 determines whether the warning stop conditions have been met, and if it determines that they have been met, it stops the warning and notification. This prevents unnecessary warnings and notifications from continuing. It also helps to guide the driver of the vehicle 9 to meet the warning stop conditions.

[0052] (1E) The notification unit 57 notifies the management device 7 if it determines that any of several specific conditions are not met. As a result, the administrator using the management device 7 can be aware of the status of the vehicle 9 and the driver.

[0053] For example, if the notification includes the driver's name, device information of warning device 3, alcohol concentration, whether or not vehicle 9 is moving, and location information of vehicle 9, the administrator can recognize that information.

[0054] (1F) If the normal power supply to the warning device 3 is lost, the capacitor 21 supplies power to the warning device 3. The notification unit 57 uses the power supply from the capacitor 21 to notify the management device 7 when the normal power supply to the warning device 3 is lost. Therefore, the administrator using the management device 7 can recognize that the warning device 3 has lost power.

[0055] (1G) The notification unit 57 periodically determines whether the warning device 3 or the equipment connected to the warning device 3 has been removed, and if it determines that it has been removed, it notifies the management device 7. Therefore, the administrator using the management device 7 can be aware of the status of the warning device 3.

[0056] (1H) When a notification is received by the management device 7, the management device 7 sets a state where a telephone or video phone can be used between the warning device 3 and the management device 7. Therefore, the administrator using the management device 7 can give instructions to the driver or hear the situation from the driver via telephone or video phone.

[0057] <Other Embodiments> Although embodiments of the present disclosure have been described above, the present disclosure is not limited to the embodiments described above and can be implemented in various modified forms.

[0058] (1) Driver identification information may be, for example, biometric information. (2) Multiple specific conditions may include other specific conditions in addition to (J1) to (J4). Also, multiple specific conditions may not include some or all of (J2) to (J4). Also, some of (J2) to (J4) may be replaced with other specific conditions.

[0059] (3) The timing of the decision may be when two or three of (a) to (c) are reached. (4) The intensity of the warning may increase over time, or it may remain constant. Examples of warning intensity include the intensity of light, the volume of sound, the magnitude of vibration, the intensity of odor, and the magnitude of electrical stimulation.

[0060] (5) The warning device 3 does not have to notify the outside of the vehicle 9. The warning device 3 does not have to notify some or all of the management device 7. The warning device 3 does not have to determine whether the warning stop conditions have been met and may continue the warning and notification unconditionally. The warning device 3 does not have to be equipped with a capacitor 21. The warning system 1 does not have to have a function to set the telephone or video phone to a usable state. (6) The warning device 3 may include some or all of the functions of the alcohol detection device 11, camera 13, reader 15, warning execution device 17, and external notification device 19.

[0061] (7) Some of the components that the vehicle 9 had in the first embodiment may be located outside the vehicle 9. For example, the alcohol detection device 11 and the camera 13 may be located outside the vehicle 9. An example of a location where the alcohol detection device 11 and the camera 13 are located is an office or the like located outside the vehicle 9.

[0062] If the alcohol detection device 11 and camera 13 are located outside the vehicle 9, the driver will use the alcohol detection device 11 to detect the alcohol concentration outside the vehicle 9. The camera 13 will also take pictures outside the vehicle 9. After that, the driver will get into the vehicle 9.

[0063] If the time elapsed between the driver's alcohol concentration being detected and their entry into vehicle 9 exceeds a certain upper limit, the warning device 3 will issue a warning prompting the driver to undergo alcohol concentration detection again. Furthermore, if the distance traveled by the driver between the alcohol concentration detection and their entry into vehicle 9 exceeds a certain upper limit, the warning device 3 will also issue a warning prompting the driver to undergo alcohol concentration detection again. The upper limits for time and distance can be set, for example, by the administrator managing vehicle 9 or the driver.

[0064] (8) The warning device 3 and its method described herein may be implemented by a dedicated computer provided by configuring a processor and memory programmed to perform one or more functions embodied by a computer program. Alternatively, the warning device 3 and its method described herein may be implemented by a dedicated computer provided by configuring a processor by one or more dedicated hardware logic circuits. Alternatively, the warning device 3 and its method described herein may be implemented by one or more dedicated computers configured by a combination of a processor and memory programmed to perform one or more functions and a processor configured by one or more hardware logic circuits. The computer program may also be stored as instructions executed by the computer on a computer-readable non-transitional tangible recording medium. The method for implementing the functions of each part included in the warning device 3 does not necessarily have to include software, and all of its functions may be implemented using one or more hardware components.

[0065] (9) The function of one component in each of the above embodiments may be divided among multiple components, or the function of multiple components may be performed by one component. Also, some of the configurations of each of the above embodiments may be omitted. Also, at least some of the configurations of each of the above embodiments may be added to, replaced with, etc., the configurations of other embodiments.

[0066] (10) In addition to the warning device 3 described above, the present disclosure can also be realized in various forms, such as a system that uses the warning device 3 as a component, a program for causing a computer to function as the warning device 3, a non-transitional physical recording medium such as a semiconductor memory on which this program is recorded, a method for manufacturing the warning device 3, and a method for managing vehicles and drivers.
