Description

[Detailed description of the invention] Road safety improvement methods and devices The present invention relates to a method and apparatus for improving traffic safety.

Major efforts in short- and medium-distance transportation of resources in developed regions of the world is carried out by individual vehicles that can carry a limited number of people.

The industry predicts that traffic will only continue to increase in the future. The demands placed on those who convert have become increasingly strict.

According to authorities, there are two completely different measures for the combination of drivers and traffic. It is said that there is a way to do this. One of them is restrictive, and is based on various laws and regulations. This is a method of strongly controlling traffic, and the discretion of the individual driver is completely eliminated. It's something that doesn't exist. The other is to rely on the individual driver's judgment and follow detailed laws and regulations. Types are not used very often.

However, it is unlikely that any of these methods will be able to effectively deal with future situations. do not have. For this reason, each country imposes strict speed limits and other strict laws. Despite this, the number of accidents is rapidly increasing. In addition, traffic congestion The flow of traffic is slow, and diesel engines are revving and idling. Not only is the environment deteriorating, but the efficiency of transportation is also significantly decreasing. .

On the contrary, the idea is to minimize the number of laws and regulations and leave it up to each driver. The method is not fully utilized anywhere in the world in areas with high traffic volumes. Ru. The idea of fewer laws and regulations is based on prudent drivers. Therefore, it is important to not only provide sufficient driving education but also to effectively improve the driving skills of drivers. culminating, advancing and stimulating.

The minimum skill required to operate a vehicle varies from country to country, but In other words, it is gradual. Therefore, even those who lack driving aptitude can drive to some extent. If you practice patiently, you can acquire some correct driving techniques and pass the test. It's put away. These situations often have nothing to do with personal characteristics. Ru. If you have not practiced traffic conditions, the danger is serious and unreasonable. This can lead to people driving in such a state and sometimes panicking.

Even if any technology is developed to improve traffic safety in the future, it will still prevent traffic accidents. It's probably impossible to eliminate them all.

Even in the 21st century, human factors will probably still influence driving.

There is no foreseeable future in which transportation systems rely on superior centralized driving control systems. It will not be more important in the future. Drive more effectively and safely Technical support for drivers is probably the most important. will be necessary.

Examples of technical support to make driving more effective include: We provide support from customers, support from the driving control side, and support regarding planned driving routes. Examples include support from the perspective of information systems that provide information on

Technical support to improve road safety is often built into the vehicle itself. It is rare. Much has been done to make vehicles safer, and driving Road safety can be improved if we pay attention to drivers and their tendency toward inappropriate driving behavior. It seems that we have reached a point where we can improve our performance. If not, technical support Advances in technology require total control of the vehicle itself, at least under limit conditions. It will be bad.

All accidents are caused by improper driving behavior by drivers. this As a result of such inappropriate driving behavior, the driver applies the brakes to stop the vehicle. , the driver turns the steering wheel without taking his foot off the brake pedal, causing a ditch or obstruction. Try to avoid things. Accidents often occur in this way.

Needless to say, the consequences of an accident become more serious when the vehicle is traveling at high speed. that's why However, this does not mean that the cause of the accident is primarily due to driving at extremely high speeds. , it is certain that accidents can easily occur. Of course, speed should not be viewed as the ``main factor'' in accidents. If the speed limit were set to zero, traffic accidents would not occur. . Nevertheless, ``human factors'' are often a secondary cause of accidents. this is Not only because the driver's judgment was incorrect in choosing the speed, but also because of the poor use of the road. Improper driving behavior of other drivers driving at high speeds can affect drivers who are driving at high speeds. This is partly due to the fact that high-speed driving is indirectly related to this. Improper driving behavior Although it is true, it is said that he has been able to maintain ``accident-free driving'' for 50 years. There are probably some converts as well. But are they causing accidents for other drivers? It is. Therefore, it detects the driver's inappropriate driving behavior and corrects it. That is important.

The reason why traffic accidents become worse is due to knowledge about before and after the accident. In other words, there is a lack of proper education and stable driving system in advance of accidents. There are times when you are not doing enough. Avoid traffic accidents and extremely dangerous situations In this case, it is the driver's understanding of the accident and the circumstances before and after it. Things disappear. Survivors and eyewitnesses, often in post-mortem investigations The traffic accident must be reconstructed by questioning the shooter. ABS brake Even with this in place, it is often not possible to analyze the skid trajectory in relation to an accident.

Therefore, in Germany, continuous memorization of driving and driver behavior is required. These memories are repeated over short or long periods of time.

In the method disclosed in US Pat. No. 4,058,796, the driving behavior of the driver is I try to recognize movements or their patterns. This pattern is a normal pattern If the vehicle is different from the current one, the driver is notified of this difference. However, this previous application The patent states that the memory pattern of driving behavior is continuously updated to the latest using an IC card. No updates have been made. Therefore, this method It is suitable for active support that continuously monitors and provides information. It is not.

The main purpose of this invention is to provide information technology that is essentially passive; Increasing traffic based on driver driving behavior and/or other driving conditions Ensure drivers are given timely and appropriate information about hazards and are aware of the driving conditions of other vehicles. It improves traffic safety without relying on drivers' age, understanding, and ability. It is intended to allow information to be updated at any time.

Another object of the present invention is to prevent improper driving behavior by providing information to the driver. In addition to reducing the danger caused by driving, it is also possible to reduce the risk of bad driving behavior. In some cases, such inappropriate driving behavior is compared with the risk of an accident and the results are evaluated. The purpose is to provide technology that allows writing on IC cards/drivers' licenses.

Based on this, drivers can be provided with appropriate training at appropriate times. this In the invention, these tasks are performed without any trouble for the driver. It is possible to do this.

In order to achieve such an object, the present invention has the features described in the features of the claims. The section is the gist.

This invention provides information about the individual hazards that the driver is about to face. and provide this information in a timely manner before a dangerous situation occurs. It can be done on a google. In other words, we provide support that is responsive to each individual situation. This can be provided to drivers who drive, and the drivers take this as real support. Give it high priority.

This invention allows for highly advanced driver training and education. Become. If the danger level of the driver's driving behavior becomes serious, further driving is prohibited. It is also possible to restrict or even make it impossible.

By employing the technology of this invention, the operational The driver can be notified of his or her driving ability. For such applications, special The normal driving behavior of a given driver, such as steering wheel and accelerator movements, can be recorded on an IC card. Remember it. The driver's behavior is continuously checked while driving and a computer is memorized. These memorized behavior patterns are compared with the driver's normal behavior. If there is a large deviation, the driver will be notified of the abnormal driving behavior. be. If the driver continues to drive inappropriately despite this information, the It is determined that the software on the computer is in a dangerous situation that exceeds the permissible level. Thus, they affect a driver's driving performance in different ways and to different degrees.

In addition, as an application aspect of this invention, if the abnormality in the driving behavior of the driver is serious, In some cases, a method called ``adding penalty points'' is adopted. This is stored on an IC card. A “fine” must be paid within, for example, 30 days in relation to the inappropriate driving behavior Information that must be used is also memorized. In many cases IC card/driver's license is also a payment card, so fines are automatically paid at appropriate times. It is. If a more elaborate approach is preferred, individual drivers may You may report to a transfer school.

In the simplest application, information about the movement of the accelerator and There is a method of memorizing and using it.

In more advanced systems, speed, clutch and brake pedals, brake Rake pedal pressure, engine speed, distance between vehicles in front and behind, lights. operation, use of directional flannel, radio and/or tape recorder It also remembers information about presence, telephone, safety belts, etc.

In addition, whether the vehicle is driving on a gravel road, a paved road, or a rough road. It may also be possible to store information from a gravity sensor such as a robot. Furthermore, the influence of wind information on the friction coefficient of the road surface (intercepted via radio), and the driver's breathing. It is also conceivable that information about the information and pulse rate may be included.

Therefore, the present invention is based on the external situation near the vehicle. and information about the driver himself/herself.

In order to realize this invention, it is necessary to consider driving conditions under various different traffic conditions. By collecting, storing and processing vast amounts of information from It is necessary to find the ``common elements'' of the movement. Therefore, for each driver It is equally important to understand the ``context'' of appropriate and inappropriate driving behavior.

First of all, even if different drivers drive on a certain road section (for example, a circumferential road), It is better to play. At this time, drivers encounter various traffic situations, so they It collects, stores and processes driving behavior. of tests that have already been carried out The results show that certain groups of drivers behave in unique ways in certain traffic situations. drivers in other groups exhibit inappropriate driving behavior in other traffic situations. It exhibits appropriate driving behavior.

If there is only one driver who behaves inappropriately, no incident will occur, but if there is one driver who behaves inappropriately, It can be extremely dangerous if two drivers with similar driving behavior are placed together in a similar traffic situation. You will experience a condition or have a dramatic accident. Such dangerous conditions are inappropriate. Several drivers with positive driving behavior are placed together in similar traffic situations. It also happens when.

Thus, according to the invention, improper driving behavior can be detected before it has serious consequences. The system recognizes inappropriate driving behavior and notifies the driver of this in a way that does not interfere with driving. We can provide the technology to do so. Precise instructions on how to implement this.

The law has no provisions in relation to "licensing" and updating IC cards/licenses. determined. In other words, cards are used as proof of ability. Sometimes da It is sufficient to equip the tushboard with clear furanone nitrite, and If so, an audio announcement may be made using a loudspeaker. In either case, the driver may experience slippage. Is it a slow road or a continuation road? Is there a traffic light or speed limit? Is there a vehicle following? Information such as whether there are any traffic closures or traffic closures is provided silently and non-dramatically. At present is the response from the driver, the actual information is given in a more obtrusive manner, and There is no "information" from "noisy radio."

The method for traffic safety according to this invention is for a long period of time, and is suitable for children aged 8 to 12 years. Starting when they were young boys, these boys were given small vehicles and put on small circuits. The aim is to encourage children to drive with proper manners and to improve their driving ability. I was born with it Collect, store and process information about actual driving behavior. This kind of method This allows us to discover driving behavior that is more characteristic of age, temperament, gender, etc. . Subsequent traffic education from knowledge of the driving behavior of drivers at these ages be carried out in a way that is suitable for each individual, while at the same time preventing anti-social behavior related to vehicles. This makes it possible to suppress the progression of the movement at an early stage.

The following example uses a microprocessor unit built into a vehicle. However, here we will collect and process various behaviors of the vehicle and driver to develop this unit. It is possible to insert an IC card/driver's license with personal information stored into the card. Furthermore, this The unit is programmed to give the driver information tailored to the individual driver. -ing

Several sensors 3a to 3f are connected to the illustrated unit 1, and these Sensors detect driving conditions, driver behavior and safety-critical behaviors. It is. The calculations and processing results performed by the central processing unit 4 are sent to the printer 5, The information is displayed on a display 6, a loudspeaker 7, and the like. interf This unit can be connected via the base 8 to a powerful e.g. stationary unit, It is also possible to replace software and control the driver's driving behavior.

Unit 1 includes activators 15a to 15d, which interface It is connected to devices, control mechanisms, etc. of the vehicle via a base 14. The driver is inappropriate If you drive in a dangerous manner, the engine's output will be clogged, and depending on the situation, such dangerous driving behavior may be avoided. The rolling behavior makes it impossible to continue driving. In such a situation, the activation Connect an appropriate external alarm indicator via the heater and the interface 14, It forces drivers of other vehicles to pay attention to this vehicle.

Program memory 9 stores various program codes selected by the producer. It is remembered. The computer memory 10 also contains vehicle standard and various operating information. Information regarding running conditions under rolling conditions is stored. In addition, external IC card The driver's license 11 stores information about the driver and his or her normal driving behavior. information regarding short or long trips the driver has undertaken in the past. It is designed to collect and memorize information. As an I’C card, it lasts about one year. Preferably one with enough memory capacity to store information related to normal driving. stomach. In addition, the cow-senodo 12 is used to issue questions to the central unit and monitor vehicle running. conditions (replacing tires, attaching a trailer, refueling time, load, number of passengers, etc.) You can also change the number, etc.). You can also use this key to e.g. Make information more active, such as when a vehicle is equipped with a car phone network It can also be exchanged.

The part 13 in the solar unit 1 regulates and controls the 12V DC voltage from the power supply. ing.
