Abstract

The method for minimising accidents on the streets is achieved through notification of danger signals from the traffic attendant to vehicles (1). A dangerous situation is communicated to other traffic attendants through a well-displayed information source (3). The information source may be generated one good and widely viewable signal or through several good and widely viewable signals. The information source may be generated through one or more firework rockets, or through one or more audible sound signals which may be in the form of sirens.

Description

technical Field of the invention

The The invention relates to a method and a warning system for equipment of the Motor vehicle to minimize accidents by timely warning of the Hazard situation in traffic.

With Increasing traffic density and traffic is driving on the streets more dangerous; by driving a following motor vehicle on a preceding vehicle elevated the number of accidents, and despite the efforts many involved in this area, including inventors, the situation becomes more critical. In numerous publications is about timely detection of a dangerous situation and contrary Dangerous measures.

From the DE 103 14 647 A1 a warning and early detection system is known in a vehicle, which in a traffic jam on the road by means of a built-in electronic early and warning recognition circuit via a control pulse immediately during braking the signal, z. As turn signals, stop lights, warning lights, or similar of the vehicle activated. This triggers a chain reaction of the warning signals emitted by the other vehicles behind. But a sufficiently large distance between successive vehicles is required. Frequently the time intervals are less than 2 seconds, then the drivers of the following vehicles will not be able to create such a chain reaction.

From DE 102 52 595 A1 For example, a warning device for vehicles is known in which an impact probability is determined by an existing crash probability unit corresponding to the relative movement between the vehicle and the front object, and at least one of the driving force and braking force of the vehicle is changed as needed. It is thereby taken into account by means of a driver intent detector and a driving intent of a driver of the vehicle and accordingly formed a warning control.

To DE 101 33 283 A1 In the warning system for collision avoidance in traffic, the signals emitted by inter-vehicle communication systems are detected and evaluated, and upon detection of a vehicle approaching at critical speed, a response is triggered.

These and also many other inventions not mentioned here see one Exposure to: either a motor vehicle equipped with a warning system or an adjacent preceding vehicle, or a follower vehicle. Several motor vehicles can unaffected Because the warning is only available through existing or inter-vehicle communication systems emitted signals, and these only a few, close seen or specially equipped vehicles seen and / or can be perceived.

In the DE 101 45 837 A1 a method and a system for timely detection of the dangerous situation is proposed in which a non-visible further signal is emitted with the optical signal, which can be received by a sensor arranged on the motor vehicle and convertible into an acoustic signal perceptible to the driver of the motor vehicle. In this case, all subsequent vehicles for receiving and processing of a non-visible signal to be equipped. The driver of a motor vehicle who has received such a warning does not know from where it came from, and where the danger looms, therefore, can not take all necessary steps against the danger in time.

The Problem of traffic safety when suddenly stopping a motor vehicle tightened yourself and earn big ones Meaning by extremely tense Traffic conditions. If the traffic density is even 4-5 cars / km does not exceed, and According to all standards, traffic is classified as "free" and does not remain with the driver a lot of possibilities to drive properly "free" Speeds on the roads 120-160 km / h (that is 40-50 m / s) a motor vehicle does not need a 5-6 sec to the distance 200-250 m up to the next, suddenly to drive through the stationary vehicle ahead. From that 1 sec. (40-50 m) on the reaction time, 2-3 sec (80-150 m) on the braking distance of a danger braking - the braking can not always from the beginning as a hazard braking met are accordingly, the braking distance is then extended. The remaining 2-3 seconds left for a real "free" ride require the driver to tense attention. He can not afford, even for short Time from the street to distract oneself.

Conditions of real road traffic are much harder. According to studies by traffic experts (eg ADACmotorwelt 10/2002 page 12), more than 30 percent of the vehicles on the left-hand lane have a gap of less than 2 seconds on the right-hand side, and nearly 20 percent of the tested vehicles on the right-hand side. Such distances are considered to be particularly critical, or at least risky. Such a powerful traffic flow can not be stopped immediately. If something happened on the street, and even suddenly stops a car for whatever reason, then many followers have no chance to avoid an impact.

Even if some followers over a danger situation are warned in time, the drivers have at the intervals about 2 sec - the ride is called column traffic - no real possibilities to do something, so as to initiate an emergency braking, without vom Folder to be impacted.

Task, which is to be solved in contrast

Of the Invention is an object of providing a method and a system for equipment a motor vehicle for the timely, safe warning of road users about a sudden Hazard situation in traffic.

Inventive solution

The Invention solves this task by providing a method with the features of claim 1 and a system having the features of the claim 10. The dependent claims contain advantageous embodiments and further developments of the invention. at In this procedure, the following vehicles are suddenly stopped by an emergency stop Motor vehicle, imminent or already happening, on special way warned. This triggers an information source that all road users affected by this case can, Immediately, without the use of any additional technical aids. She will be enough too striking, not to be overlooked by any rider driving behind be.

One Dangerous state, imminent before the release of a Emergency braking, or already happening in an emergency braking, or already happening on impact, is by a direct from other road users who may be affected by it, well conspicuous source of information so designated (shown) that Every road user reacts to the danger immediately, the changed situation understand, and immediately necessary conclusions pulls out of the situation of things. He can measure the distance from the place of the incident, the traffic density of the front and rear of his vehicle and many others, for a correct assessment of the traffic situation necessary parameters, determine. If possible and when needed, the driver can brake his vehicle, or one Initiate emergency brakes. If a driver finds out more follower vehicles because of the road conditions can not get a hazard warning, he can by connecting of the own warning system form a new source of information and forward the danger warning.

At the Procedures should not necessarily all vehicles be equipped with a hazard warning system; although the more there are, the safer the journey becomes. It is enough if only a few motor vehicles such a system for hazard warning contain.

at a further developed according to claim 2 method is the information source by a good and widely visible signal, or several good and far produces visible signals.

at an advantageous embodiment of the method according to claim 3 the source of information is generated by one or more firework rockets, according to claim 4 are for Formation of a source of information well-floating and noticeable fine Particles, particles, powders, light tapes used.

drawings

The advantageous embodiments The invention are explained in more detail below with reference to the drawings and described. Showing:

1 a schematic representation of driving on the road motor vehicles in the upcoming emergency stop;

2 a schematic representation of an exemplary arrangement of built-in means for forming an information source;

3 a schematic representation of an exemplary arrangement of removable and always attached to the surface of a motor vehicle facilities for forming an information source;

4a and 4b schematic detailed representations of a built-in cartridge for forming an information source in each case in a normal state of readiness and in use;

5 schematic representation of the installation of a cartridge for forming an information source in one of the attachments.

The journey of the motor vehicle 1 in 1 becomes an obstacle 2 obstructed, and an accident can only be prevented by emergency braking. To the following vehicles 4 To notify about the imminent emergency stop of the trip, will be at sufficient altitude from the motor vehicle 1 an information source 3 educated. In the example given, these are a few firework rockets. These are immediately and immediately perceived by the following road users, even if they did not see them themselves on impact, and only the source of information - the fireworks rocket they noticed. You get a serious, non-overlooked warning that something has happened in the front, you have to be extremely careful and attentive.

visual Immediate perceptions of a hazard warning may be from others To be accomplished. Instead of the fireworks rocket can in the height of what kind Cartridge with tightly packed fine particles are thrown. On the necessary Height the cartridge is opened and the contents of them are in the air scattered. The cartridges are made of any fine particles, particles, Powder, light ribbons filled. The fabric should of course good floating, well noticeable, maybe more shiny be.

In 2 For example, an arrangement of the predetermined warning devices installed for forming an information source in a car is shown. They are housed in the hollow space adjacent to the surface of a passenger car and connected to the motor vehicle's electronic network by a control unit. The following possible locations are indicated: under the bonnet 6 , under the roof of the vehicle 7 , on the back sidewall 8th ; in the rear bumper 9 ; on the back wall 10 ; at the front fender 11 , These and some other possible configurations of the information devices are possible in the assembly, or in the reconstruction of a motor vehicle and are in the following in the consideration of the 4 illustrated in detail. Special place possesses the under number 5 designated accommodation of a device in the existing, rear curvature of the side mirror. This belongs to the use of attachments of the motor vehicle and can take place when installing a spare mirror with already installed information cartridge. Furthermore, such an example with a bumper in the consideration of 5 shown.

Thus, such arrangement of the facilities of in 3 shown application of removable ( 12 at the roof, 13 at a door, 14 at the rear) or always stabilized ( 15 on the rear wall) similar to facilities in which no major reconstruction of the existing vehicle for use of the method is required. This advantage also significantly extends the use of the method and makes it suitable for existing motor vehicles. The information facilities 12 - 14 be prepared with the possibility of temporary, if necessary by the driver himself installation on the surface of the motor vehicle, and can in a known manner, for. B. be set up by means of a magnetic or vacuum pad. Unlike them the information devices 15 stay constantly on the surface of the motor vehicle. In this case, the conditions of air resistance should be taken into account, and preferably they may be arranged on the rear parts.

In 4a and 4b is a possible detailed illustration of how an information cartridge may be stored at the rear of the surface of the cart. Opening in the sheet metal 16 The bodywork of a motor vehicle comes with a gap 17 closed it. Gap is by means of the hinge 18 attached to the inner surface of the sheet and carries on itself a container 19 for an information cartridge 20 , Normally, the gap is cushioned by a spring, or a pneumatic means for opening, and by means of a snap closure (not shown in the drawing) maintains the information cartridge ready for use within the interior cavity of the carriage.

When the information device is triggered 4b will the gap 17 released from the lock, opened, and at the same time the information cartridge is thrown.

In 5 For example, an arrangement of the information cartridge 21 in one of the attachments, in the front bumper of a motor vehicle shown. It is located with the container 22 in a polyurethane filled bumper 23 which in this example is made as a plastic shell. When used, the information cartridge is shut off by the bumper in the bumper 24 thrown open mouth.

Operation of a Information system can be selected by the driver manually, or automatically, without his participation - at the emergency braking, or be met on impact. This can too simultaneously with the triggering an airbag system, or even low deformation of a Body pressed become. Suitable for safe release The warning system will accommodate information cartridges and starting devices in the crumple zones of the motor vehicle. Upon impact, the Information cartridge by the very first deformation of this auto part hurled immediately.

simultaneously with visual hazard warning also a sound signal is triggered. This can both by a signal horn present in the motor vehicle, as also by means of additional installed siren be realized. Switching on the sound signal done with these straight means that are for use of the visual effect be used. The facilities are with electronic network of the motor vehicle wired through a control unit. Automatic triggering of the warning system can also in the deformation of the motor vehicle constructions mechanical action on their switch-on and / or shut-off devices occur.

All before for Systems of hazard warnings proposed for a passenger car apply in full of mass for respective motor vehicle.

use of the method and warning system for minimizing accidents the streets elevated essential road safety, reduces the risk of accidents and makes the ride more comfortable.
