Description

The present invention relates to a driver condition confirmation system and a driver condition confirmation method.

The Ministry of Health, Labor and Welfare has established “Sleep Guidelines for Health Promotion 2014”, and in recent years, sleep is considered to be an important element for living a healthy life. In accordance with this guideline, the Ministry of Land, Infrastructure, Transport and Tourism's Passenger Vehicle Transportation Business Transportation Regulations and Freight Vehicle Transportation Business Transportation Safety Regulations make a roll call to the driver (driving target person) and It is required to report whether or not there is a risk of being unable to drive, and it is basically necessary to confirm the sleep state face-to-face during a roll call.
In addition, a driver state confirmation system for easily performing such a roll call of a driver has been proposed (for example, see Patent Document 1).

Japanese Patent No. 6007161

However, even if a face-to-face roll call is performed, it is difficult to determine the fatigue or sleep state of the driving target person, for example, because the sleeping time required by the driving target person is different or the lifestyle is different. In some cases, it is difficult to confirm the sleep state with the above-described conventional driver state confirmation system. In roll call, when it is difficult to confirm the sleep state only by face-to-face confirmation, it is considered to refer to biological information during sleep.

The present invention has been made in view of such circumstances, and an object thereof is to provide a driver state confirmation system and a driver state confirmation method capable of easily confirming a sleep state.

In order to solve the above-mentioned problem, one mode of the present invention confirms the 1st questionnaire result which shows the answer result of a driving subject to the question performed beforehand including a question about sleep, and the state of the driving subject. And a second questionnaire result indicating the answer result of the driving target person to the question regarding the feeling of sleep including at least the sleep time, and the first questionnaire result acquired by the acquisition unit. And a state confirmation unit that determines whether or not the driving target person is in a drivable state based on the second questionnaire result.

Further, according to one aspect of the present invention, when the acquisition unit confirms the first questionnaire result indicating the answer result of the driving target person to the questions that are executed in advance including the question regarding sleep, and the state of the driving target person. The second step of acquiring a second questionnaire result indicating the answer result of the driving target person to the question regarding the feeling of sleep including at least the sleep time, and the state confirmation unit includes the first step acquired by the acquisition step. It is a driver state confirmation method including a state confirmation step of determining whether or not the driving target person is in a drivable state based on the result of the first questionnaire and the result of the second questionnaire.

According to the present invention, the sleep state can be easily confirmed.

Although the configuration in which each one is provided is described, a plurality of each may be provided.

The terminal device 20 is, for example, a tablet terminal, a notebook-type or desktop-type personal computer, a smartphone, or the like, and is subject to a pre-questionnaire (first questionnaire) or daily roll-call questionnaire (second questionnaire) by a driver or an administrator. Answer of questionnaire) is input. The terminal device 20 transmits the entered answers to the prior questionnaire or the daily roll call questionnaire to the driver status confirmation device 10 via the network NW1.

The sensor sheet 31 (an example of a biological information measuring unit) is a sheet-type sensor, and is, for example, a piezoelectric sensor that detects pressure acting in the film thickness direction. The sensor sheet 31 is provided, for example, under the mattress of the bed where the driving target person sleeps, or between the mattress when a plurality of mattresses is provided, such as a two-layered mattress, The movement of the user when there is a person who is in bed operation is detected. The sensor sheet 31 outputs the detection result to the communication control device 32.

The communication control device 32 acquires the electric signal detected by the sensor sheet 31. The communication control device 32 calculates the biological information of the driving target person by analyzing the acquired electric signal. The communication control device 32 extracts, for example, a signal in a predetermined frequency band corresponding to heartbeat, respiration, and body movement by filtering the obtained electric signal, and based on the extracted signal, the heartbeat per unit time is extracted. Calculate the number, breathing rate, and presence/absence of body movement. Further, the communication control device 32 calculates the sleep depth (for example, phase coherence λ) of the driving target person based on the calculated heart rate of the driving target person. The communication control device 32 transmits the calculated biometric information of the driving target person to the driver state confirmation device 10 via the network NW1.

The posture sensor 41 (an example of a driving state detection unit) detects the driving posture of the driving target person. The attitude sensor 41 outputs the detected attitude data during driving to the communication control device 43. By installing the posture sensor 41, the inclination of the posture of the driving target person during driving can be known, and thus it is possible to determine whether or not the driver is dozing.

Here, the "driver ID" is an example of driver identification information for identifying a driving target person. Moreover, "group information" indicates information indicating a group. In the present embodiment, the driving target person is classified into one of the four groups, group A to group D, based on the result of the preliminary questionnaire conducted in advance.
The example shown in FIG. 5 indicates that the “group information” of the driving target person whose “driver ID” corresponds to “U0001” is “group A”.

Here, the groups in the present embodiment will be described with reference to FIG.
FIG. 6 is a diagram showing an example of determination information for each group in the present embodiment.
As shown in FIG. 6, the “group information” includes “group A”, “group B”, “group C”, and “group D”.

“Group A” is a group that has been designated as “excellent” in terms of the state related to daily sleep based on the results of the preliminary questionnaire, and when confirming the state of the driving target person, only voluntary application for roll call is made every day. Confirmation is performed based on.
In addition, “Group B” is a group in which the state related to daily sleep is “good” based on the result of the preliminary questionnaire, and when confirming the state of the driving target person, voluntary application of roll call every day, If necessary, confirmation is performed based on the biological information during sleep.

In addition, “Group C” is a group in which the state related to daily sleep is set to “OK” based on the result of the preliminary questionnaire, and when confirming the state of the driving target person, voluntary application of the roll call is made every day. The confirmation is performed based on the biological information during sleep and the confirmation of the management department.
In addition, “Group D” is a group in which the state related to daily sleep is set to “impossible” based on the result of the preliminary questionnaire, such as confirmation of biological information during daily sleep and taking a sleep improvement class. After implementing the measures, re-evaluate (re-classify) the driving target person.

Returning to the explanation of FIG. 1 again, the daily roll call information storage unit 114 stores the result of the daily roll call questionnaire for each driving target person. The daily roll call questionnaire (second questionnaire) is carried out, for example, at the time of waking up on the day when the driving work is performed or before the start of the driving work, and when checking the state of the driving target person. The daily roll call questionnaire is, for example, a questionnaire as shown in FIG. 7, and includes a question about a feeling of sleep including at least sleep time.

As shown in FIG. 8, the daily roll call information storage unit 114 has a “driver ID”, “implementation date”, “sleep place”, “sleep time”, “wake-up time”, and “sleep time”. And other questionnaire results are stored in association with each other. The results of the questionnaire show that the first factor is factor I (wake-up drowsiness), the second factor is factor II (sleeping and sleep maintenance), the third factor is factor III (dream), and the fourth factor. Factor IV (recovery from fatigue) and factor V, factor V (sleep time), are included.

For details of the sleep wakefulness questionnaire and Factors I to V, see "Yukamoto Yamamoto, Hideki Tanaka, Miki Takase, Katsuo Yamazaki, Kazuo Azumi, Shuichiro Shirakawa: OSA sleep for middle-aged and elderly people. Development and standardization of feeling survey form (MA version), Medicine of brain and psychiatry 10:401-409, 1999”.

The daily roll call information storage unit 114 stores, for example, a standardized score of factors I to V, a score of factors I to V of 50 or more, and a score of 40 or more.
For example, in the example shown in FIG. 8, the "execution date" of the driver subject corresponding to the "driver ID" of "U0001" is "2018/10/1" and the "sleep place" is the "remote location". It indicates that the "sleep time" was "5.58" hours. Further, in this case, it is shown that the “number of factors with 50 points or more” of factors I to V is “2” and the “number of factors with 40 points or more” is “5”.

Returning to the explanation of FIG. 1 again, the sleep biological information storage unit 115 stores the biological information during sleep measured by the sensor sheet 31. The sleep biometric information storage unit 115 stores, for example, biometric information as shown in FIG. 9, a driver ID, and a measurement date in association with each other.
FIG. 9: is a figure which shows an example of the biometric information measured at the time of sleep in this embodiment.

Returning to the description of FIG. 1 again, the driving state information storage unit 116 stores the driving state information indicating the driving state of the driving target detected by the posture sensor 41 and the drive recorder 42. The driving state information storage unit 116 stores, for example, a driver ID, date and time information, and driving state information in association with each other.

The confirmation result storage unit 117 stores the determination result of whether or not the driving target person, which is determined by the driving state confirmation device 10 by checking the driving target person's state including the sleep state, is in a drivable state. Here, an example of data in the confirmation result storage unit 117 will be described with reference to FIG.
FIG. 10 is a diagram showing an example of data in the confirmation result storage unit 117 in this embodiment.

As illustrated in FIG. 10, the confirmation result storage unit 117 stores the “driver ID”, the “implementation date”, and the “judgment result” in association with each other. Here, the “implementation date” indicates the implementation date when it is determined whether or not the driving target person is in a drivable state.
For example, in the example shown in FIG. 10, the “execution date” of the driving target person whose “driver ID” is “U0001” is “2018/10/2”, and the “determination result” is “drivable”. Is shown. In addition, it is indicated that the “determination result” of the “execution date” of the driving target person is “2018/10/3” is “operation is impossible”.

Returning to the explanation of FIG. 1 again, the incentive information storage unit 118 stores the incentive points (privilege points) given to the driver in the driver state confirmation system 1. The incentive points include sleep incentive points, which are special points granted to the sleep state of the driving target person, and the driving state of the driving target person according to the result of the preliminary questionnaire or the daily roll call questionnaire result. Accordingly, driving incentive points, which are the bonus points to be given, are included. Here, an example of data in the incentive information storage unit 118 will be described with reference to FIG. 11.

FIG. 11 is a diagram showing an example of data in the incentive information storage unit 118 in this embodiment.
As illustrated in FIG. 11, the incentive information storage unit 118 stores “driver ID” and “incentive points” (“sleep” and “driving”) in association with each other. Here, "sleep" of "incentive points" indicates the above-mentioned sleep incentive points, and "driving" indicates driving incentive points.

Returning to the explanation of FIG. 1 again, the control unit 12 is, for example, a processor including a CPU (Central Processing Unit) and the like, and controls the driver state confirmation device 10 as a whole. The control unit 12 includes a preliminary questionnaire processing unit 121, a daily roll call processing unit 122, a sleep biological information processing unit 123, an information acquisition unit 124, a state confirmation unit 125, a sleep incentive providing unit 126, and a driving management unit 127. And a driving incentive providing unit 128.

The pre-questionnaire processing unit 121 executes a process for conducting a pre-questionnaire as shown in FIG. 3 to the driving target person on a regular basis, for example, every one month or every six months. The pre-questionnaire processing unit 121 acquires, for example, the reply to the pre-questionnaire input from the terminal device 20 as the pre-questionnaire result via the network NW1. Further, the preliminary questionnaire processing unit 121 calculates the score of the driving target person based on the acquired answers to the preliminary questionnaire. As shown in FIG. 4 described above, the pre-questionnaire processing unit 121 associates the “driver ID”, “implementation date”, “pre-questionnaire result”, and “score” with each other, and pre-questionnaire information storage unit It is stored in 112.

The daily roll call processing unit 122 executes a daily roll call questionnaire as shown in FIG. 7, for example, at the time of waking up on a day when a driving task is performed or before starting the driving task. The daily roll call processing unit 122 acquires, for example, the answer of the daily roll call questionnaire input from the terminal device 20 as the daily roll call questionnaire result via the network NW1.

In addition, the daily roll call processing unit 122, for example, based on the answers of the acquired daily roll call questionnaire, for example, the standardized score of factors I to V, the number of scores of factors I to V of 50 or more, and 40 or more. Is calculated as the result of the roll call questionnaire every day. As shown in FIG. 8, the daily roll call processing unit 122 includes the answers of the acquired daily roll call questionnaire, the “driver ID”, the “implementation date”, the “sleep place”, and the calculated daily roll call questionnaire. The result is associated with each other and stored in the roll call information storage unit 114 every day. The daily roll call processing unit 122 may also manage, for example, a conventional roll call table that is uniquely created and used for each carrier.

The sleep biometric information processing unit 123 acquires the biometric information of the driving target person (for example, biometric information as illustrated in FIG. 9) transmitted from the communication control device 32 via the network NW1, and acquires the acquired biometric information and the driving information. The person ID and the measurement date are associated with each other and stored in the sleep biological information storage unit 115.

The information acquisition unit 124 (an example of an acquisition unit) acquires the above-described preliminary questionnaire result and daily roll call questionnaire result. The information acquisition unit 124 acquires, for example, the preliminary questionnaire result corresponding to the driver ID of the driving target person from the preliminary questionnaire information storage unit 112. Further, the information acquisition unit 124 acquires, for example, the daily roll call questionnaire result corresponding to the driver ID of the driving target person from the daily roll call information storage unit 114.

The state confirmation unit 125 determines whether or not the driving target person is in a drivable state based on the preliminary questionnaire result and the daily roll call questionnaire result acquired by the information acquisition unit 124. The state confirmation unit 125 classifies the driving target person into any one of a plurality of groups based on the result of the preliminary questionnaire, for example, based on the daily roll call questionnaire result and the additional confirmation information according to the classified group. , It is determined whether the driving target person is in a drivable state.

Specifically, the state confirmation unit 125 classifies the driving target person into any of the above-mentioned "group A" to "group D" based on the result of the preliminary questionnaire (for example, the score). The state confirmation unit 125 stores the classified groups in the group information storage unit 113 in association with the driver ID, as shown in FIG. 5, for example.
If the classified group is “Group D”, the state related to daily sleep is “impossible”, and therefore the state confirmation unit 125 uses the sensor sheet 31 for a predetermined period such as one week. The target person is caused to perform measurement of the existing biometric information, and based on the biometric information, it is determined again whether or not it is possible to change to the “group C” in which the driving task is possible. When it is determined that the state can be changed to “group C”, the state confirmation unit 125 changes the “group D” to the “group C”, associates it with the driver ID, and stores it in the group information storage unit 113. Let

In addition, when the state checking unit 125 determines in the re-determination that the group cannot be changed to “group C” (“group D”), the state checker 125 takes measures such as letting the driving target person take a sleep improvement course (sleep improvement program). After implementation, re-evaluate (re-classify) the driving target person.

In addition, when confirming the state of the driving target person, the state checking unit 125 acquires the group information corresponding to the driver ID of the driving target person from the group information storage unit 113, and uses it as the acquired group information of the driving target person. Accordingly, different determination information is used to determine whether or not the driving target person is in a drivable state.

For example, when the group information is “group A”, the state confirmation unit 125 indicates that the information acquisition unit 124 is in a drivable state by the driving target person based on the daily roll call questionnaire result (voluntary application of the driving target person). Or not. In this case, the state confirmation unit 125 determines, for example, whether or not the number of factors I to V of the driving target person's daily roll call questionnaire result of 50 or more is “3” or more. It is determined whether the driving target person is in a drivable state. That is, the state confirmation unit 125 determines that the driving target person is in a drivable state when the number of the scores of the factor I to the factor V of 50 points or more is “3” or more.

The state confirmation unit 125 may change the determination criterion for determining whether or not the driving target person is in a drivable state according to the work status of the driving target person. For example, when the “sleep place” is “normal” such as when working from home, the state checking unit 125 determines the score of Factor I to Factor V by the number of 50 or more, and makes a business trip or the like. When the “sleep place” of is a “remote place”, the scores of factors I to V may be determined by a number of 40 or more. The state confirmation unit 125, for example, as the work status of the driving target person, a driving time zone (night work, daytime work, early morning work, etc.), driving distance (long-distance driving, short-distance driving, etc.) ), the determination criterion may be changed according to the driving route (whether the driving route is monotonous on an expressway or complicated such as a mountain road).

In addition, for example, when the group information is “group B”, the state confirmation unit 125 causes the information acquisition unit 124 to determine the daily roll call questionnaire result (voluntary application of the driving target person) and the driving target person as additional confirmation information. Based on the biological information measured during sleep, it is determined whether the driving target person is in a drivable state. In this case, the state confirmation unit 125, for example, the number of factors I to V of the driver's daily roll call questionnaire result of 50 or more is “3” or more, and the sleep biological information storage unit 115. When there is no problem in the sleeping state in the biological information of the driving target person during sleep stored by, the driving target person is determined to be in a drivable state.

Further, for example, when the group information is “group C”, the state confirmation unit 125 causes the information acquisition unit 124 to determine the daily roll call questionnaire result (voluntary application of the driving target person) and the driving target person as additional confirmation information. Based on the biological information measured during sleep and direct confirmation by the management department, it is determined whether or not the driving target person is in a drivable state. In this case, the state confirmation unit 125 confirms, for example, in the above-mentioned voluntary application of the driving target person and the biological information of the driving target person during sleep when there is no problem in the sleeping state, and a direct question etc. by the management department. If there is no problem with, it is determined that the driving target person is in a drivable state.

As described above, the state confirmation unit 125 determines whether or not the driving target person is in a drivable state in one of the plurality of groups based on the daily roll call questionnaire result without additional confirmation information. To judge. Then, the state confirmation unit 125 determines whether or not the driving target person is in a drivable state based on the daily roll call questionnaire result and the biological information in at least one other group of the plurality of groups. To do.
Further, the state confirmation unit 125 stores the determination result of whether or not the determined driving target person is in the drivable state in the confirmation result storage unit 117, as shown in FIG. 10 described above.

The sleep incentive giving unit 126 (an example of a sleep privilege giving unit) gives a sleep incentive point (privilege point) for the sleep state of the driving target person in accordance with the result of the preliminary questionnaire or the result of the daily roll call questionnaire. The sleep incentive giving unit 126 gives a sleep incentive point, for example, when it is determined in the preliminary questionnaire result or the daily roll call questionnaire result that a good sleep state is maintained. The sleep incentive giving unit 126 stores the point obtained by adding the given sleep incentive points in the “sleep” of the “incentive points” corresponding to the “driver ID” of the driving target person of the incentive information storage unit 118, and the incentive Update points.

The sleep incentive point is used to maintain or improve the motivation of the driving target person by recognizing the driving target person having a high point as an excellent driving target person who maintains a good sleep state.

The driving management unit 127 generates a proposal regarding safe driving for the driving target person in accordance with the driving state detected by the posture sensor 41 and the drive recorder 42. The operation management unit 127 acquires, for example, the operation status information indicating the in-operation status transmitted from the communication control device 43 via the network NW1, and acquires the acquired operation status information, the driver ID, and the date and time information. The information is associated and stored in the operating state information storage unit 116.

Further, the driving management unit 127 monitors the driving state of the driving target person on the basis of the driving state information stored in the driving state information storage unit 116, and for example, it is found that the driver is about to fall asleep while driving, or that there is a sign of fatigue. In this case, the driver is notified of a break. The driving management unit 127 may notify the driving target person via the communication control device 43 as a notification for prompting the driving target person to take a break, or by using a telephone, an email, an SNS (Social Networking Service), or the like. You may make it notify a driving subject.
In addition, for example, when the vehicle being driven is compatible with automatic driving, the driving management unit 127 may perform automatic driving when it is found that the driver is about to fall asleep or has sudden illness or fatigue. The vehicle may be stopped safely according to.

The driving incentive giving unit 128 (an example of a driving privilege giving unit) gives a driving incentive point (privilege point) to the driving target person in accordance with the driving state detected by the posture sensor 41 and the drive recorder 42). .. The driving incentive giving unit 128 gives a driving incentive point when it is determined that the safe driving is maintained based on the driving state information stored in the driving state information storage unit 116, for example. The driving incentive giving unit 128 stores the point obtained by adding the given driving incentive points in the “driving” of the “incentive points” corresponding to the “driver ID” of the driving target person of the incentive information storage unit 118, and the incentive Update points.

The driving incentive points are used to maintain or improve the motivation of the driving target person by certifying the driving target person with a high number of points as an excellent driver and commending it or changing the insurance application conditions.

Next, the operation of the driver state confirmation system 1 according to the present embodiment will be described with reference to the drawings.
FIG. 12 is a flowchart showing an example of group classification processing of the driver state confirmation system 1 according to this embodiment. The process illustrated in FIG. 12 is performed on the driving target person at regular intervals, such as once a month or half a year.
