Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an accident suppression system for reducing the occurrence of accidents caused by a vehicle or a machine when a driver of a vehicle, an operator of a machine tool or the like loses consciousness or cannot operate normally. Regarding the method.

[0002]

2. Description of the Related Art Automobiles are indispensable for modern business activities and social life, and are used in all aspects of logistics, commuting, leisure and the like. On the other hand, many car accidents occur every year, and effective measures for preventing accidents are desired.

[0003] As to the circumstances of the current occurrence of accidents, there are many cases in which passengers, other vehicles, and pedestrians (elementary school students, elderly people, etc.) are involved in accidents from one vehicle, and this is caused by the age of young and old people. There is a tendency for the incidence of accidents to occur. As a countermeasure, it is conceivable to create a new driver's mark for young drivers and a mark for old people, or to conduct a license return campaign. Institute for Traffic Accident Analysis (institute for traf
fic accident research and data analysis, ITARD
According to the analysis result of the traffic accident in 1995 (A version) by A), the car accident is classified into the following three vehicle classes. (1) Sports & Specialty, RV (recreational)
vehicle): The average value of danger recognition speed for night accidents, youth accidents, and vehicle-only accidents is high. Therefore, there is a tendency for the driver to quickly recognize when a dangerous state occurs. (2) Family light passenger car, 1BOX: The ratio of night accidents and single vehicle accidents is lower than in other classes. Family mini-cars have more female driver accidents than other categories. In 1BOX, the accident of the age group of 30-49 years old is increasing. Compared to other classes, the average value of the perceived danger speed of a single vehicle accident is lower. Therefore, there is a tendency that the driver's recognition when a dangerous state occurs is delayed. (3) Sedan and wagon: show intermediate features between the above two classes.

[0004] In addition, the situation of the driver at the time of occurrence of an accident includes drinking, looking aside (distraction), falling asleep, erroneous operation such as making a mistake between a brake and an accelerator, and loss of consciousness due to heart failure or brain disease. In addition, the surrounding environment at the time of the accident includes a road environment including an environment invisible to the driver and an environment in which the driver cannot judge, an environment that applies a psychological stress to the driver, and the like.

[0005] Among them, the driver's aside and drowsiness can be determined from the inclination of the face in the driver's image by the system described in Japanese Patent Application No. 10-960 (driver monitoring device). . In this system, when the driver is in a dangerous state, a warning is issued to the driver.

[0006]

However, the conventional driver monitoring method has the following problems. Judgments based on the inclination of the driver's face can detect situations such as looking aside or falling asleep, but it is extremely difficult to detect other situations. For example, drinking, misoperation,
It is difficult to detect situations such as heart failure and brain disease.

[0007] Even if a warning is issued to the driver, it is not always possible that an accident will occur if the driver is asleep, loses consciousness, or cannot drive normally due to illness or the like. Not reduced.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an accident suppression system and method for monitoring a monitoring target person such as a driver and surrounding conditions and performing appropriate processing for accident suppression according to the situation. .

[0009]

FIG. 1 is a diagram showing the principle of an accident suppression system according to the present invention. According to a first principle of the present invention, an accident suppression system includes a sensor unit 1, a detection unit 2,
And processing means 3. The sensor means 1 inputs the status information of the person to be monitored. The detecting means 2 detects an abnormality by comparing the pre-recorded status information of the monitored person with the input status information. And the processing means 3
When an abnormality is detected, appropriate processing for suppressing an accident is performed.

When the sensor means 1 inputs the status information of the person to be monitored, the detecting means 2 searches for the recorded status information corresponding to the status information, compares the two, and compares the two with each other. Find out if there are any. Then, when an abnormality is detected, the processing unit 3 performs an appropriate process according to the situation information, and suppresses an accident.

The monitored person is a person who may cause an accident, such as a driver of a vehicle, an operator of a machine tool, and the like. This is information indicating the current situation of the monitoring target person, such as image information and information related to operations such as a steering wheel. The normal value of the status information is recorded in advance,
By comparing the recorded status information with the input status information, an abnormal status can be detected.

When an abnormality is detected, the processing means 3 issues a warning to a person to be monitored, stops a vehicle or a machine operated by the person to be monitored, or notifies a nearby person of occurrence of danger. Or make emergency arrangements.

[0013] This makes it possible to detect an abnormality in the health condition, physical function, and the like of the monitored person, and to prevent or reduce an accident according to various situations.
According to the second principle of the present invention, the accident suppression system includes a sensor unit 1, a detection unit 2, a processing unit 3, and a determination unit 4. The sensor unit 1 inputs monitoring target person or surrounding situation information. The detecting means 2 detects an abnormality from the input status information. The determination means 4 issues a warning to the monitoring target when an abnormality is detected, and determines whether the monitoring target is in a dangerous situation based on a response to the warning. Then, the processing means 3 performs an appropriate process for suppressing an accident when the monitored person is in a dangerous situation.

When the sensor means 1 inputs the status information of the monitored person or the surrounding status information, the detecting means 2 checks whether or not the input status information is abnormal. If an abnormality is detected, the determination means 4 issues a warning to the monitored person,
Check if there is a response from the monitored person, and if so, the response speed. Then, when it is determined that the monitored person is in a dangerous situation, the processing means 3 performs an appropriate process according to the situation information, and suppresses an accident.

The input surrounding situation information is information indicating the current situation around the monitoring subject, such as the temperature, humidity, and the amount of carbon monoxide around the monitoring subject. If the status information of the monitored person or the surrounding status information indicates an abnormal value,
The monitored person may be in a dangerous situation. Therefore,
The determining unit 4 issues a warning using voice or vibration, and determines that the monitoring target is in a dangerous situation if there is no response from the monitoring target or if the response is slow.

As described above, by judging the danger based on the response of the monitored person, it is possible to detect whether the consciousness and the physical function of the monitored person are normal, and to prevent or reduce the accident. Can be.

According to a third principle of the present invention, the accident suppression system includes a sensor unit 1, a processing unit 3, and a judgment unit 4. The sensor means 1 inputs information about the driver of the vehicle or surrounding conditions. The determination means 4 determines whether the driver is in a dangerous situation based on the input situation information. Then, the processing unit 3 performs an appropriate process for stopping the vehicle when the driver is in a dangerous situation.

When the sensor means 1 inputs the situation information of the driver of the vehicle or the surrounding situation information, the judging means 4 performs processing such as abnormal value detection and danger judgment using the inputted situation information. When the driver determines that the driver is in a dangerous situation, the processing means 3 performs automatic driving up to the stop position according to the situation information,
Appropriate processing such as deceleration of the vehicle is performed to stop the vehicle. By automatically stopping the vehicle, accidents can be prevented or reduced even when the driver cannot drive normally.

For example, the sensor means 1 in FIG. 1 corresponds to a temperature sensor 12, a carbon monoxide sensor 13, and a sensor system 14 in FIG. 2 described later, and the detecting means 2 and the judging means 4 correspond to the personal card in FIG. 15 and observation system 16
, The processing means 3 includes the wake-up device 11, the processing system 17, the notification system 18, and the notification system 1 of FIG.
9 corresponds.

[0020]

Embodiments of the present invention will be described below in detail with reference to the drawings. In this embodiment, when the driver loses consciousness or cannot drive normally, the vehicle predicts danger and determines whether the driver can drive. Then, appropriate processing for avoiding danger is performed according to the situation inside and outside the vehicle, thereby preventing accidents and reducing the scale of the accidents.

As a method for predicting a danger, a method is used in which a driver or the like and a situation inside and outside the vehicle are monitored by a sensor or the like, and a danger is determined when an observed value changes from a normal value to an abnormal value.

For example, a measuring instrument such as a thermometer, a sphygmomanometer or a pulse meter is provided in a vehicle, and an abnormal value is detected by comparing the measured value with a normal value in daily life and a normal value during driving. As a result, the health condition of the driver can be monitored, and in particular, danger can be effectively predicted for the elderly. For drunk driving and drowsy driving, for example, danger can be predicted from driving driving conditions such as sudden steering control. The following method is used as a method for avoiding danger. (1) A warning is issued to the driver to increase the driver's danger recognition speed. (2) Automatic guidance or automatic control is performed to stop operation, stop fuel supply, automatically decelerate, or prevent the accelerator from functioning (prohibiting acceleration) according to the situation. (3) Notify the surrounding vehicle of the driver's danger by using a voice, a direction indicator, or the like. (4) Notify the driver's situation to the expressway center, police, fire department, etc., and make emergency arrangements as necessary. (5) Automatically maintain the internal environment of the vehicle. For example, when the room temperature reaches 50 degrees or higher, the operation of the air conditioner is started or the window is opened. If the concentration of carbon monoxide exceeds a certain level, it will warn the driver,
Notify the expressway center, police, fire department, etc.

FIG. 2 is a configuration diagram of such an accident suppression system. The accident suppression system in FIG. 2 is configured using, for example, a computer, and includes a wake-up device 11, a temperature sensor 12, a carbon monoxide sensor 13, a sensor system 14, a personal card 15, an observation system 16, a processing system 17,

The processing system 17 instructs the wake-up device 11 to issue a warning to the driver 20, and the wake-up device 11 alerts the driver 20 by using sound, vibration, or the like. Further, the processing system 17 instructs the reporting system 18 to report an emergency, and the reporting system 18 reports the occurrence of danger to the reporting destination 21 such as an expressway center, police, or emergency center. At this time, the notification system 18 instructs the notification system 19 to notify the surroundings, and the notification system 19 notifies surrounding vehicles, pedestrians, and the like of danger by using a voice, a direction indicator, or the like.

The personal card 15 is a card-type recording medium such as a wireless card and a personal computer card (PC card), and has a configuration as shown in FIG.
The personal information and the license information 31 include identification information (ID) of the driver 20, personal information such as blood type, height, weight, and the like, and information described in the license.

The daily life normal value 32 includes, for example, values of the blood pressure, the body temperature, the pulse, the respiration, the electroencephalogram, etc. of the driver 20 measured in the daily life. These data are measured and input in advance at home, hospital, police and the like. The normal value 33 at the time of driving the vehicle is, for example, an average value of normal values at the time of driving for each item of the normal value 32 of daily life. In addition, the average value of the normal values of other sensor information indicating the line of sight, the operation of the steering wheel, and the like is also included in the normal value 33 during vehicle operation.

The value 34 indicating an abnormality is a value determined to indicate an abnormality according to the regulations of a hospital or the like with respect to each of the above items. For example, data described in a medical book or the like includes personal information and license information. 31 are set in consideration of the age, body type (height, weight), and the like included in 31. Further, abnormal values of other sensor information indicating the line of sight, the operation of the steering wheel, and the like are also recorded in advance.

The input / output interface 37 includes an external input / output terminal for wired communication, and includes a wireless device for wireless communication.

FIG. 4 shows an example of the arrangement of devices in a vehicle using the accident suppression system of FIG. In FIG. 4, a driver 20 sits on a seat 41 and operates a steering wheel 42 to drive.

The in-vehicle antenna 43, the line-of-sight sensor 44, the steering wheel sensor 45, and the measuring device 46 are included in the sensor system 14 of FIG. 2 and operate in cooperation with the observation system 16. The line-of-sight sensor 44 is attached to, for example, a rearview mirror and inputs an image of the face of the driver 20. Driver 2
By inputting the image of the 0th eye, it is possible to detect whether or not the subject is asleep. The handle sensor 45 includes the handle 4
2 for detecting the rotation direction, rotation angle, and the like of the handle 42.

The measuring device 46 is mounted on, for example, the arm or wrist of the driver 20, and includes sensors such as a sphygmomanometer and a thermometer. Then, the measurement data is wirelessly transmitted to the in-vehicle antenna 43,
The in-vehicle antenna 43 transmits the received data to the observation system 16 wirelessly or by wire. The personal card 15 is inserted into the observation system 16, and the situation of the driver 20 is monitored based on the information of the personal card 15.

The speaker 47 and the vibration device 48 are included in the wake-up device 11 shown in FIG. The speaker 47 outputs a message for calling attention when the driver 20 may fall asleep. The vibration device 48 vibrates the seat 41 to wake up the sleeping driver 20.

For example, the speaker 47 outputs a message such as "Are you awake? If so, press the handle switch." in this case,
The steering wheel 42 is provided with a steering wheel switch 49 as shown in FIG. 5. When the driver 20 presses the message within a predetermined time after the message is output, it is regarded that the message has been recognized. Thereby, it is confirmed whether the driver 20 is conscious.

FIG. 6 is a flowchart of a process performed by the accident suppression system of FIG. First, the temperature sensor 12, the carbon monoxide sensor 13, and the sensor system 14 input information about the driver 20 and the inside and outside of the vehicle, and the observation system 16 performs monitoring based on the input information (Step S).
1). At this time, the measuring device 46 of FIG.
Measurement values such as body temperature, blood pressure, pulse, and respiratory rate are input.

The principal card 15 holds, for example, data as shown in FIG. In the table of FIG. 7, for each item of systolic blood pressure, diastolic blood pressure, pulse, body temperature, and respiratory rate, current values, past driving histories, allowable ranges of medical normal values,
And past abnormal values are recorded. Of these, regarding the past operating history and the allowable range of medical normal values,
The minimum value, the normal value, and the maximum value are recorded, and the past abnormal values are recorded with the minimum value and the maximum value.

The temperature sensor 12 inputs the temperature inside and outside the vehicle, and the carbon monoxide sensor 13 inputs the amount of carbon monoxide in the vehicle. The allowable range of the temperature and the amount of carbon monoxide is stored in the observation system 16 in advance.

The observation system 16 compares the sensor information with its permissible range, and determines the detection of an abnormal value (step S).
2). In particular, if the difference between the current value and the normal value in the past operation is larger than a predetermined value, it is determined that there is an abnormality. If the past operation history data has not been written, the allowable range of the medical normal value or the normal daily life value 32 in FIG. 3 is used instead.

If no abnormal value is detected, step S1
Is repeated, and if an abnormal value is detected, the awakening device 1
1 issues a warning to the driver 20 (step S3). Here, for example, the speaker 47 emits a sound that surprises the driver 20, or the vibration device 48 causes the seat to vibrate.

Then, the observation system 16 determines the driver 20's consciousness disorder based on the response speed of the driver 20 to the warning, and determines the necessity of stopping the vehicle (step S4). Here, a voice message is output to the driver 20, and if the reaction speed is slow or there is no response, it is determined that the vehicle needs to be stopped.

For example, a message such as "Do you want to stop the vehicle?" Is output and the driver 20 is inquired of the necessity of stopping the vehicle. In this case, a response phrase such as "Yes" or "No" is determined in advance, and the voice of the response is input using a microphone. Then, if the driver 20 gives a positive reply, gives a reply other than the determined phrase, or does not reply within the designated time, it is determined that the vehicle needs to be stopped. If a negative reply is given, it is determined that there is no need to stop the vehicle.

Alternatively, a message such as "Are you awake? If so, press the handle switch." Is output, and if the driver 20 presses the handle switch 49 in FIG. 5, a normal response is obtained. It is determined that there is no need to stop the vehicle. If the handlebar switch 49 is not pressed within the designated time, it is determined that there is no normal response and the vehicle needs to be stopped.

If it is not necessary to stop the vehicle, the driver 20 is inquired of whether or not it is necessary to make an emergency or the like (step S5). If there is a reply that no arrangement is necessary, awakening device 1
1 issues a warning to the driver 20 (step S6). Here, for example, a message such as a caution or recommendation for driving is output, and the current value of the sensor information is recorded as an abnormal value on the principal card 15. Then, the processing after step S1 is repeated.

If it is determined in step S4 that the vehicle needs to be stopped, the vehicle is automatically stopped (step S4).
7). Here, the deceleration process is started according to the judgment of the observation system 16. First, it is determined whether the vehicle can be stopped.

For example, on an expressway, radio waves for evacuation guidance are constantly output from an emergency telephone, and guidance is performed to the deceleration stop position by automatic driving according to the radio waves.
At this time, the notification system 19 notifies the surrounding vehicles of the urgency using a turn signal and a voice. Also, on general roads,
Urgency is notified to nearby vehicles by turn signals and voice. As the stop position, a roadside zone or the like is selected, and the vehicle is guided by radio waves from the road so as not to stop under a signal or the like.

Next, an inquiry is made to the driver 20 as to whether or not it is necessary to make an emergency or the like (step S8). If there is a response indicating that the arrangement is unnecessary, the current value of the sensor information is recorded as an abnormal value on the principal card 15, and the fact that the vehicle stop process has been performed is also recorded (step S9), and the process ends.

In step S8, if there is a response indicating that an arrangement is required, or if there is no response within the designated time, the notification system 18 automatically transfers prescribed data to the notification destination 21 and requests an emergency arrangement. (Step S1
0). The transferred data is recorded on the personal card 15.

On an expressway, an emergency telephone, an emergency request system, and the like are included in the report destination 21, and a GPS (global positioni) is used.
ng system), patient data including sensor information about the driver 20, other situation data, and the like. The notification system 18 can also use a radio emission tube or a notification device in a conventional mobile system.

Then, the observation system 16 proceeds to step S
The processing of No. 9 is performed, and the processing ends. Step S
In step 5, even if there is a reply indicating that arrangement is necessary or if there is no reply within the designated time, the processing after step S10 is also performed.

When the consciousness disorder is determined using the eye-gaze sensor 44 shown in FIG. 4, the accident suppression system performs a process as shown in FIG. First, the observation system 16
Sets the line-of-sight sensor 44 in accordance with the instruction from the driver 20 (step S11).

For example, when the driver 20 is worried about not falling asleep during driving, the driver 20 instructs the activation of the line-of-sight sensor 44 and issues a "warning upon detection of an abnormal value" or a "periodic warning". Set. In the case of "periodic warning", a warning period (for example, once every 5 minutes) can be specified, and if the driver 20 does not occur even after the warning, the warning is specified to be continued. Can also.

The following processing in steps S12 to S21 is basically the same as the processing in steps S1 to S10 in FIG. In step S12, in addition to the measuring device 46,
Image data from the line-of-sight sensor 44 is input to the observation system 16. The observation system 16 detects an abnormal value by comparing the image of the eyes of the driver 20 with a previously recorded image.

FIG. 9 shows the difference between a normal eye image and a sleepy eye image. For example, the feature amount extracted from the normal eye image data is recorded on the principal card 15 in advance, and the feature amount is extracted from the eye image data input by the eye sensor 44 and compared with the normal feature amount. . Then, based on an appropriate similarity calculation, it is determined whether or not the input eye image data indicates an abnormal value.

When the size of the pupil is used as the feature quantity,
By recognizing the vertical length of the pupil, it is possible to monitor the degree of eyelid opening. Then, when the difference between the current pupil length and the normal pupil length is equal to or greater than a predetermined value, it is determined to be an abnormal value. This state is considered to correspond to a situation in which the driver 20 becomes sleepy and the eyelids are closed.

In step S13, when an abnormal value is detected or when a designated cycle has elapsed according to the setting, it is determined that a warning needs to be issued, and the processing in step S14 and subsequent steps is performed. Depending on your settings,
The warning in step S14 is continuously performed.

In step S15, in addition to the response speed to the voice message,
It is determined whether or not the vehicle needs to be stopped in consideration of the image data from. For example, if the feature value extracted from the eye image data returns to a normal value, it is determined that the driver 20 is awake, and it is determined that the vehicle need not be stopped.

Similar processing is performed when the situation of the driver 20 is monitored using the steering wheel sensor 45 of FIG. In this case, the sensor information during normal operation is recorded in advance on the principal card 15 and the observation system 16
Detects an abnormal value by comparing the current sensor information with the recorded sensor information.

In the above embodiment, a system for mainly monitoring a driver of a vehicle and the surrounding environment has been described. However, an operator who operates other equipment such as a machine tool can prevent accidents by using a similar system. Can be planned. In this case, the accident suppression system performs a process of stopping the operation of the device, etc., instead of the vehicle stop process.
