CONSTITUTION:When a voice signal of 'get ready, please' is issued by a speaker 8, the driver touches to a push button 9 and when the buzzer of a test start signal is issued, the driver 1 pushes the push button 9. Thereby, the voice signal from speakers 8, 8' or such notice as the 'yes or no' judgement by luminous lamps 11, 12, 13 is issued by the elapse of a time between both cases. Then, it is decided whether the operation is continued or rest is taken by judging whether said driver's 1 operation sense for braking, etc., is normal or not. Therefore, it can be timely judged whether the operation sense for braking, etc., during the driver's operation is normal or not and safety operation can be maintained by deciding whether the continue of the operation or taking a rest at a nearest position.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION [0002] The disclosed technology has a normal driving operation caused by drowsiness while driving a vehicle such as an automobile.
It belongs to the technical field of a check system capable of preventing a paralysis of a feeling that an emergency braking operation cannot be performed and maintaining safe driving.

[0002]

2. Description of the Related Art As is well known, in Japan, where the land is narrow and the terrain conditions are close to the coastline where mountainous forest areas are intricately involved, not only agricultural and livestock farming, but also housing and facilities of various companies The plains that can be effectively used in the area are limited, and therefore, these facilities are scattered in various places regardless of the urban area and the rural area. Therefore, the railways, roads, and communication networks that communicate the traffic and information between these areas. Is networked all over the country, and the functions of various vehicles such as automobiles and railways that run on the ground are not only mere human transportation, but also various goods, regardless of the aircraft flying in the aerial corridor. In addition, it has even the function of information transmission, and its social importance is increasing more and more recently.

However, some vehicles, such as high-tech trains in urban areas, use an automatic electromagnetic induction system using a computer, but many vehicles, such as trains and trains, use humans. It is important to say that the driving is dominated by automatic driving, and that even in the case of an automatic electromagnetic induction type vehicle, it is necessary to finally perform driving by confirmation work by human driving. is there.

By the way, although I always feel when driving a vehicle such as an automobile, I often get drowsiness in monotonous driving. This is a professional driver such as a taxi or a truck. However, there is a problem in that sensory paralysis after 1 to 2 hours of eating is always accompanied by danger and may lead to catastrophe in an unexpected situation.

In order to prevent the paralyzed sensation caused by drowsiness while driving a vehicle such as an automobile, the body is regularly warmed up at a resting place through regular education and training. , Take a rest,
Although I try to change my mood, it is extremely difficult to overcome the drowsiness that attacks regularly and irregularly as experienced in local driving etc. in truck drivers etc. Therefore, There is a constant demand for not only drivers as individuals but also for society to maintain safe driving against such drowsiness. High-tech technology has been devised and used in part by vibrating the driver's seat and spraying air fresheners to eliminate the drowsiness and ensure safe driving of the driver.

[0006]

However, the safe driving guarantee technology using such a so-called high-tech technology is such a countermeasure for coping therapy, which does not lead to a feeling object of drowsiness. As long as it is not a technology for controlling the feeling of the driver of a vehicle such as an automobile, it has a drawback that safe driving cannot be guaranteed.

[0007]

By the way, as described in the training texts at the driving school for driving a car, when a driver perceives a danger and operates a brake, the situation is usually judged visually. There is a free running distance until the brain actually feels the danger state and the brain feels this to command the operation of the brake pedal as soon as possible and the brake actually operates, and the brake is actually operated as prescribed. It is said that it takes 0.8 seconds or so from the perceived state until the
It turns out that it is extremely important that the braking sensation is regulated during the second.

Therefore, the braking feeling within the 0.8 seconds can be governed by the physiological structures and functions of the human optic nerve, etc., but the braking technique within and outside the 0.8 seconds time range. Further, the technique for determining whether or not the braking feeling for the braking operation is normal can be sufficiently revealed, and informs the driver whether or not normal driving is possible.

In the invention of this application, the time response of such a braking feeling within a range related to the braking operation, for example, 0 or 8 seconds, is preferably set during the period during which normal operation is normally performed, or when preparation is made. The basic precondition is to be able to make a pass / fail judgment during the period.

[0010]

It is an object of the invention of the present application to perceive the situation in which it is necessary to perform a braking operation through the above-mentioned visual sense based on the above-mentioned prior art, and to achieve a free running distance within a predetermined short time such as 0.8 seconds. A mechanical judgment is made as to whether or not it is a normal judgment of the feeling of being able to actually operate the brake operation upon completion, and the driver's feeling is extracted as it is, and as it is. Pass / fail judgment is made based on the feeling of, and if it is within the range of passing, brake operation is performed,
When a rejection is judged, it is highly likely that the most dangerous situation may occur as an emergency evacuation, and by issuing an instruction to immediately take a break, it is an excellent benefit to the safety technology application field in the transportation industry. It aims to provide a safe driving maintenance system.

[0011]

In order to solve the above-mentioned problems, the structure of the invention of this application, which is based on the above-mentioned object, is intended for driving a vehicle such as a taxi or a truck. According to the standard programmed in advance according to the speed in the driving area, the driver's hearing senses normal driving feeling such as braking by the audio signal from the optimal angle position such as 15 ° diagonally forward and upward. In order to test whether or not the test start signal is given by the voice signal from the speaker at a predetermined (desired) timing, the driver who hears the test signal pushes the push-push button provided at the predetermined position to set the predetermined circuit. Calculates the test start signal and the response time by the push-button in a predetermined manner, and whether it is the push-button at the set timing in the speed of the vehicle in the running area. Or the display by the lamp, and,
If there is a blinking display with a display lamp such as scramble, and if you feel that you are significantly behind the specified timing, you are instructed to immediately take an emergency evacuation at the nearest resting place, and about the mechanism of these operations. Is equipped with a switch that stops when the brake or the brake is not used, and with these selective start / stop switches, and also with a switch that can control the switching of the cycle regarding the time of braking feeling. It is a technical measure that allows flexible operation and allows the driver to always maintain the safe driving of the vehicle he or she is driving.

[0012]

Embodiments of the invention of this application will be described below with reference to the drawings.

The illustrated mode is a mode in which the vehicle is installed and provided in the driver's seat of an automobile as a vehicle, and the automobile can be applied to various things such as taxis, trucks, buses and the like.

As schematically shown in the embodiment shown in FIG. 1, the driver 1 normally sits on the seat 2 and visually checks the dashboard 3 while operating the brake pedal 4 as usual. The driver's operation is performed while operating with his / her feet and visually recognizing the panel 5 of the safe driving holding system having a drowsy driving preventing function which is the center of the gist of the invention of this application.

The external shape of the panel 5 of the safe driving maintenance system is as shown in FIG. 2, and the frame 6 having a predetermined thickness and having a substantially rectangular shape in a front view has a drows-preventing safe driving at the top. An appropriate name 7 of the safe driving maintenance system such as a maintenance device is given, and a speaker 8 is provided on the lower one side.

Incidentally, as shown in FIG. 1, about 15 in front of the driver.
Other loudspeakers 8'having a strong directivity can be installed at optimal positions such as °, and both loudspeakers 8 and 8'can be selectively switched.

A slightly larger push-button button 9 is provided below the speaker 8 of the panel 5, and the push-button buttons 9 are vertically arranged in four rows at the front of the push-button button 9. Four small acrylic light-emitting lamps 11 and 12 each showing the time required to push the button 9 (in the upper lamp 11, 0.2 seconds, 0.4 seconds ... Indicators are shown, and the lower lamp 12 has indicators at intervals of 0.3 seconds such as 0.3 seconds, 0.6 seconds, etc.). In between the light emitting lamps 11 and 12, a predetermined number of red or orange warning lamps 13 and 13 are arranged in a predetermined number, and scramble display is performed by a blinking lamp at irregular random timing. It is arranged.

Further, a buzzer button 14, a brake button 15, and a light emitting lamp 1 are provided on a lower edge portion of the system panel 5.
A high-speed / low-speed mode switching button 16 for 1 and 12 and a timer switching switch 17 for speakers 8 and 8'are provided, and a main switch 18 is provided at the rightmost end.

The connection circuits in the frame 6 of the above-mentioned switches are arranged as shown in the circuit diagram through the sequencer computer shown in FIG.

The flowchart of the safe driving maintenance system of the invention of this application is as shown in FIG.

In order to operate the safe driving maintenance system of the invention of this application in the above-mentioned configuration, the main switch 18
Is turned on (as a matter of course, the main switch 18 is turned off when the vehicle is not parked or stopped), and the mode switch button is used on general roads other than highways. 16 standard (ST
The light emitting lamp 12 side below the light emitting lamps 11 and 12 is turned on by switching to D), and the length of the sensing time of the time when the driver operates the brake from when the driver feels danger is slightly longer than the expressway. Try to set it as you feel it.

Further, the timer changeover switch 17 is also changed over to a predetermined time side and is set so that a test start signal is emitted from the speaker 8 or 8 ', for example, at intervals of 3 minutes.

Therefore, as shown in FIG. 4, the speakers 8 and 8 ′ “Please prepare” at a predetermined timing during operation.
, The driver places his / her hand on the green push-button 9 and waits for the test start signal from the speaker 8, 8 '.

Therefore, at the set timing, the speaker 8,
When the buzzer sound of the predetermined test start signal is emitted by 8 ', the driver pushes the push-button 9 concerned as soon as possible (although there may be a time delay due to drowsiness etc. at that time). When pressed, the light emitting lamps 11 and 12 corresponding to the time from when the test start signal is transmitted through the flag circuit until the push-push button 9 is pressed (to be precise, within the upper limit of the time) are turned on, For example, if the light-emitting lamp 11 lights for 0.6 seconds and the brake operation is actually performed in preparation for the danger, the danger is avoided and the braking feeling normally operates there. That is, the speaker 8 or 8'provides a pass determination generation signal of "passed", and those operations are repeated within the range of standard (STD) defined by the mode switching button 16, The timer changeover switch 17 is 3
The above-described operation is repeatedly performed at the minute intervals, so that the driver can appropriately determine the feeling of driving operation such as braking without having time to get drowsiness during driving.

During this time, that is, while driving on a normal road, the brakes may be frequently operated. In this case, the above-described judgment of the braking feeling is determined by the speakers 8, 8 '.
In this case, it is not preferable that the push-button button 9 that responds to the operation be actively operated. Therefore, in this case, the brake button 15 is turned off or the main switch 18 is turned off. It is also possible to switch to the side so as not to operate.

Therefore, when the buzzer sound of the test start signal is emitted and, for example, the push-push button 9 is pushed after 0.9 seconds, it goes without saying that the brake operation is performed beyond the above-mentioned free running distance. In case of loss of urgency, the 0.9-second light-emitting lamp 12 will be activated and the warning signal from the speakers 8, 8'will be "dangerous. Please concentrate your attention." It is issued as a kind of preliminary rejection voice signal, and the driver 1 is issued the warning signal, thereby concentrating consciousness and concentrating all nerves for driving.

When the test start signal is issued and the push-push button 9 is pressed for 1.2 seconds or the like, the driver 1 is in a state of being unsuitable for driving an automobile. Therefore, in this case, the light-emitting lamp 12 for 1.2 seconds is turned on, or the warning lamp group 13 of a more or less colored color is flickered violently, and the "most dangerous" from the speakers 8 and 8 '. Please take a break immediately. ”A voice sensation is frequently emitted, and the driver accordingly takes a sufficient break in the nearest parking lot to have a sense of danger avoidance.

In this way, it is necessary to determine whether or not the driver is driving a vehicle on a general road, that is, the normal feeling of the danger feeling and the braking feeling to cope with the danger. In addition, dangers on open roads are automatically avoided.

Of course, it is needless to say that sufficient rest must be obtained prior to driving so as to eliminate the operation of the safe driving maintenance system.

On the other hand, on an expressway, as is well known, the occurrence of danger will cause more serious damage than an ordinary road.
Therefore, it is necessary to determine whether or not a special braking feeling is passed during driving on the highway. Therefore, the mode switching button 16 on the highway has a light emitting lamp 11 on the upper side.
Blinks frequently, and the timer changeover switch 17 is switched at intervals of 6 minutes, etc., and while driving on the expressway, the speaker 8, 8'provides a voice signal "Please prepare." Then, the driver 1 puts his or her hand on the push-button 9 and waits for a test start signal to be transmitted from the speakers 8 and 8 '. When the test start signal is transmitted, the push-button 9 is pressed to If the time between the transmission of the start signal and the motion signal of the push-button 9 is 0.6 seconds, the light emitting lamp 11 on the upper side for the 0.6 seconds is turned on and "Successful" is given from the speaker 8, 8 '. The sound signal of "." Is issued, and the pass / fail judgment signal is issued within about one minute in a recycling process. Therefore, the driver 1 should start and continue the driving.
Since it is determined that the drowsiness may strike within minutes, the speaker 8, 8 is used each time in this embodiment.
Then, a voice signal "Please prepare."
Therefore, when the buzzer sound of the test start signal is emitted, the driver 1 presses the push-and-return button 9, and if the time between them is 0.8 seconds, the audio signal from the speaker 8, 8'is "dangerous". Please concentrate your consciousness. ", And the light-emitting lamp 11 for 0.8 seconds is turned on, and the driver 1 senses this and concentrates his nerves to drive.

Thus, for example, if the difference between the beep sound of the test start signal for 1.0 second and the push-down time of the push-button 9 is equal to the upper limit value of the pass / fail judgment, it is within the dangerous time range.
From the speaker, "Dangerous. Please focus your attention."
The driver 1 parks at the nearest resting place and takes a predetermined rest, or drives with all the nerves concentrated.

If the pushing time of the pushing button 9 is long, the speaker 8 or 8'shows "the most dangerous. Please take a break immediately" via the flag as shown in FIG. Is issued, the light-emitting lamp 11 is turned on, and the warning lamp 13 randomly blinks to notify the driver 1 that the driving is extremely dangerous, and the driver 1 immediately returns to the nearest location. Be sure to park in the parking lot and take a prescribed break.

Of course, when the brake is used during a traffic jam on a highway or when the turn signal is used, the safe driving maintenance system is made to stop its function by switching the brake button 15 to the proper side.

Further, the timer changeover switch 17 can be changed to long or short up to about 10 times and can be automatically returned from the 11th time, and the mode changeover button 16 can be handled like a game machine. It can be used for.

In this way, in the safe driving maintenance system of the invention of this application, the driving operation feeling such as braking while the driver 1 is driving on a highway or an ordinary road is an emergency evacuation in that driving. The pass / fail judgment of suitability can be accurately and properly judged, and the suitability of the sense of drowsiness or the like can be objectively judged.
You can always drive safely.

Of course, the embodiment of the invention of this application is not limited to the above-mentioned embodiment. For example, the applicable object is not only a vehicle used by a professional driver such as a taxi or a truck, but also an ordinary bus. Also applicable to passenger cars,
The present invention is applicable to all the drivers inevitably experiencing a sense of driving operation such as braking due to sleepiness that is inevitably near, or to those that need to be avoided from a state close to this.

Further, various modes such as a simulation type device for education and training can be adopted.

As for the speaker and the like, it goes without saying that a speaker such as a radio set or a radio-cassette set which is generally mounted on a vehicle can be used.

Note that only one of the warning by the speaker and the warning notification by the signal from the light may be used, and it is possible to design using a directional speaker or the like for the notification through the speaker by the voice signal. In addition, regarding the light-emitting lamps, the yellow lamps are randomly displayed at the time of the warning such as "Dangerous. Please concentrate your attention."
In addition, a random warning with a red lamp may be appropriately adopted for the maximum warning display such as "The most dangerous. Please take a break immediately."

[0040]

As described above, according to the invention of the present application, there is basically a vehicle such as a vehicle or an automobile which can be freely driven on a highway or a general road regardless of whether the distance is a taxi, a truck or the like. And driving safely by artificially testing at a predetermined timing whether or not the braking sensation that senses the danger of drowsiness that the driver can even say that he or she experiences everyday is normal. In the system that enables the driver to perform a test start signal by voice to the driver at the desired timing, the driver presses the push-button to push the test start signal and the time elapses of the push-button. It is possible to display the pass / fail judgment to the driver by electronically measuring and displaying the light emission lamp and / or at least one of the sound signal transmission. The iber can immediately know whether or not the braking feeling in the driving is appropriate, and if it does not pass, the driver can concentrate on driving and take a predetermined break in the nearest parking area. Can be taken sufficiently, thereby providing an excellent effect of avoiding an unexpected situation.

The electric instrumentation in the safe operation and maintenance system can be designed without any difficulty for those skilled in the art at the time of the invention of this application.

Further, since the pass / fail judgment lamp is composed of a large number of scramble display type blinking lamps, the driver can be strongly aware that the braking sensation at the time of the pass / fail judgment is unsuitable, so that the driver is drowsy. Even if it is being attacked by a car, etc., it is possible to immediately recognize that the driving sensation such as braking in the future is not suitable, and immediately take a break in the nearest parking lot etc. The excellent effect of being able to act quickly is exhibited.

Further, since the mode switching button can be switched between high speed and low speed, the warning cycle on the ordinary road and the highway can be switched optimally according to the road. effective.

Further, since the timer switch can be switched at a predetermined interval, the driver can use the safe driving maintenance system at the timer interval, and can achieve a kind of refreshment. It is possible to achieve the excellent effect.

By doing so, in the safe driving maintenance system of the invention of this application, a so-called high-tech mechanism for imparting rocking or vibration of the seat of the old driver to wake up the sleep is used. Since it is not a thing, the structure is simple and maintenance, inspection, maintenance etc. are almost unnecessary,
There is no failure, and therefore, there is an effect that the initial cost and the maintenance cost are not required, and the durability is favorably maintained.

Further, various mechanical parts have an advantage that they can be easily mounted including a driver, and also have an advantage that they can be mounted with sufficient rigidity and have good durability.

Further, since the paralysis of driving sensation such as braking of drowsiness or the like which originally occurs in the driver can be objectively measured separately from the driver's consciousness and the judgment of the pass or fail can be notified to the driver. If it is possible for the driver to intentionally press the lighting button promptly for the test start signal,
On the contrary, the consciousness at that time has an advantage that the effect of accelerating the wakefulness of driving sensation such as braking is produced.
