Description

The present invention relates to a system and a method for avoiding a collision of a vehicle with an at least temporarily unnoticeable for a user of the vehicle unnoticeable moving object.

Especially in the period from July to December, accidents or collisions between motor vehicles and animals occur more frequently, especially in forest areas or forest edge areas. It often happens that wild animals foraging also in urban environments, where they can even be native, since they are living spaces with attractive living conditions. This is due to the ever higher motorized vehicles to more serious damage in collisions with such "abandoned" wild animals.

Accordingly, it is desirable to provide a way to warn the driver of the motor vehicle in good time, thereby avoiding such collisions.

To achieve this object, the present invention provides a system and a method having the features of the independent claims. Embodiments are described in the dependent claims and the following description.

According to the invention, a system is provided for preventing a collision of a vehicle with a vehicle at least temporarily for a user of the vehicle undetachably moving object, the system having at least one transponder configured to be arranged to operate the system on the moving object, and at least one reader adapted to operate the system on the vehicle and / or at least one vehicle-mounted communicative point, wherein, upon operation of the system, the at least one reader disposed at the vehicle and / or at the hub has radio frequency radio waves into and out of the vehicle Environment, and the transponder arranged on the moving object, which picks up radio waves emitted by the reader when the object is in the environment to be passed by the vehicle, and in response sends out itself radio waves with object-specific data, the taken by the reader, along with vehik elspezifischen data transmitted to a computing unit implemented in a cloud and evaluated with the help of the cloud included and callable by the reader computing unit and the user of the vehicle provided.

The central arithmetic unit is designed to process the object-specific and the vehicle-specific data, based on the data behavior or movement parameters of both the vehicle and at least temporarily unnoticeable for the vehicle moving object in the vehicle passed by or to determining a potential danger for a collision between the vehicle and the object.

A provision of the evaluated data takes place in a possible embodiment on a display arranged in or on the vehicle and / or audibly via a loudspeaker arranged in or on the vehicle.

In the context of the present disclosure, a "object moving unnoticeably for a user of the vehicle at least at times" is intended to mean an object which, for the user of the vehicle, is due to the fact that that the user at least temporarily can not perceive this object in normal use of the vehicle to be expected by the user, is not calculable when passing the environment and therefore has a risk potential for a collision with the vehicle. In the following, the wording "for a user of the vehicle at least temporarily unnoticeable moving object" and "for the vehicle at least temporarily unnoticeable moving object" used synonymous with each other.

In the context of the present disclosure, a "reader" is a device that includes software that controls the reading process, and middleware that interfaces with other computer systems and databases, and that itself can act as an active transponder, i. Not only can you receive data via radio waves, but you can also send them out yourself.

"Object-specific data" comprise data that describe or characterize the object, in particular with regard to its behavior with respect to the vehicle or with respect to the environment to be passed by the vehicle.

"Vehicle-specific data" includes data that characterizes the vehicle, in particular its motion behavior in the environment passed by the vehicle.

If, in an environment, several support points, each equipped with a reader, are provided, for example, on the edge of a road traveled by the vehicle, the vehicle itself becomes, through its reader, at least one of the readers of the points detected as soon as it comes into the respective range of at least one reader. The detection of the vehicle itself is then transmitted from the at least one reading device to the cloud or to the computing unit implemented therein. The arithmetic unit can now calculate its movement pattern on the basis of the transmitted data relating to the vehicle, ie, for example, in which direction it drives as fast. Along with information with respect to possibly at least temporarily for a user of the vehicle unnoticeable in the environment moving objects that also, if they come into the range of at least one of the readers at the bases, detected by the corresponding readers of the bases and transmitted to the arithmetic unit, the Arithmetic unit by adjusting the calculated movement pattern for the vehicle with the respective movement patterns determined for the further detected objects determine whether there is a potential risk of collision for the vehicle with one of the objects detected in the environment.

The interaction or combination of stationary active transmitters in the form of the readers at the support points and at least one non-stationary transmitter in the form of the reader in or on the vehicle permits a very accurate detection of both a movement pattern of the vehicle and a movement pattern relevant to it at least an object located in the environment being passed by the vehicle.

Due to the inventive use of cloud computing (German: decentralized computer cloud), the processing of the data is outsourced, ie made outside of the respective vehicle, whereby the data processing and processing is not subject to proprietary software and / or hardware of a vehicle, in particular a manufacturer of the vehicle, which reduces costs, ensures better and safer deployment and, if necessary, enables standardization. Cloud computing is generally understood to mean an execution of programs that are not installed on a local computer, here a computing unit assigned to the respective vehicle, but run on another computer which is called up remotely (for example via the Internet) , In technical terms, cloud computing describes the approach of providing IT infrastructures (eg computing capacity and computing power, data storage, network capacities or even finished software) over a network, in particular via the Internet, without them being available on the local computer , here in the vehicle, must be installed.

The computing unit implemented in the cloud is designed to receive and process data from readers arranged either at respective support points and / or from readers arranged in or on respective vehicles. Since the arithmetic unit thereby usually receives a great deal of information describing the movements of objects, including vehicles, in certain environments, the arithmetic unit is able to merge the information and, for specific environments or regions, to provide movement patterns for the individual objects and in particular to make available to the moving in the respective environments vehicles in a processed manner. Communication between the cloud, i. The computing unit and the vehicle are typically via a cellular network, i. over a data channel, such as 3G, 4G or 5G. However, the respective channel is only activated if there is a need to transmit data. Otherwise the channel is deactivated.

A base equipped with a reader can either be connected to the cloud via a telephone landline network and / or via a mobile radio network or be connected to the cloud. Preferably, the readers are connected to the cloud via the fixed network or the readers have their own Local Area Network (LAN) for a portion of the environment in which they are arranged, such as a roadside section, this section in turn to an antenna ( BTS / NodeB) connected and ultimately connected to the cloud or connectable. This in turn means that readers located at interpolation points are connected together in an entire area covered by the LAN and can exchange data therewith. If one of the readers is now located in an area not covered by the mobile network, it can nevertheless receive data from the cloud via the communication path LAN ↔ mobile network, ie via one or more intermediate readers, as well as send data thereto. The fixed network refers here the entirety of all public landline telephone networks.

According to one embodiment of the system according to the invention, the reading device is configured to be arranged on a vehicle which is selected from the group consisting of a land vehicle, a watercraft and an aircraft. In this case, the land vehicle may preferably be a motor vehicle or any other two- or multi-wheeled vehicle. For example, a vessel may be a motorized boat or a non-motorized boat, such as a sailboat. Also under water operated vehicles are covered by the term "watercraft". The aircraft may be, for example, a passenger plane, a helicopter, a glider, a paraglider, a kite or an unmanned aerial object. However, it must always be ensured that the respective reader arranged there has a power supply, i. a motor and / or a battery-like device is available to power the reader and operate it.

In a further embodiment of the system according to the invention, the preferably passive transponder is designed to be arranged in clothing and / or in a movement aid, such as a wheelchair of a human, and / or in a body region of an animal. It is also conceivable bulky transport vehicles, such as a heavy transport, especially in confusing regions, equipped with a respective transponder in order to reduce potential accident hazards.

The proposed system is intended in particular to protect objects imperceptibly moving for a user of the system, such as, for example, children, elderly and / or animals, from an accident with a vehicle moved by the user, by the user of the system and the vehicle be warned in good time that a particular object is usually unconsciously approaching the route used by the vehicle and showing tendencies to cross the route. Accordingly, the user can take precautions or can automatically suitable precautions are activated or initiated, so that the vehicle can avoid the object.

According to one embodiment of the system according to the invention, the transponder is an RFID chip (Radio Frequency Identification).

As already mentioned above, the transponder can be a passive transponder, such as a passive RFID chip, which does not have its own power supply, so that no replacement or recharging of a battery or a rechargeable battery is necessary. As soon as the passive transponder, such as the passive RFID chip of emitting units, such as the reader by the radiated radio waves receives an energy induction, he gets even enough energy to radio waves in response to the incoming radio waves also with corresponding data regarding. of the object assigned to it.

In a further embodiment of the system according to the invention, the radio waves emitted by the transponder comprise data characterizing the object, which at least occasionally moves unnoticeably for the vehicle. For example, they include information as to which animal or type of animal it is, which size, such as length, height and width, which weight, which movement patterns and what danger in relation to the traffic it has. This animal may also be a bird. Birds in particular can cause great damage in the event of a collision with a windshield of a motor vehicle or an aircraft and pose a great danger.

In a further refinement, the system further comprises a central data acquisition device communicatively connected to the central processing unit and adapted to receive the data comprising the radio waves emitted by the transponder, wherein specific, in particular periodic, repetitions of certain data items in the central data acquisition unit, Movement pattern of certain objects are deposited, where the system is configured to use the arithmetic unit in combination with the central data acquisition unit to create movement patterns of a particular type of objects that are predominantly located in particular regions and, if necessary, the vehicle, particularly during or prior to passing one of the particular regions through the vehicle and as soon as the vehicle is detected by emitting radio waves through its reader as being in or near one of the designated regions, automatically and preventively.

In a further refinement, the arithmetic unit is also in communicative communication with a central data acquisition device which is designed to record the data comprising the radio waves emitted by the transponder. Furthermore, the arithmetic unit is designed to process the data by determining behavioral or movement patterns of the object, unnoticeable at least intermittently for the vehicle, in the environment passed by the vehicle on the basis of the data, and from this a potential danger of the vehicle at least temporarily calculated for the vehicle unnoticeable moving object for the vehicle. With the arithmetic unit in combination with the central data acquisition, for example, patterns of behavior of a certain type of animals, which are predominantly located in certain regions, can be created and made available as needed. If, for example, a vehicle enters one of these specific regions and the reading device arranged in it transmits radio waves, then it is first detected as such by reading devices arranged at respective roadside points, which in turn is communicated to the computing unit located in the cloud. The arithmetic unit can now provide feedback to the vehicle either directly or via the respective interpolation points with regard to the animals encountered in this particular region and their potential danger potential. In parallel, the reading device of the vehicle itself can, of course, receive feedback (s) from objects within the range of the emitted radio waves via the transmission of the radio waves. This direct feedback from the environment can now forward the reader to the computing unit in the cloud for further processing or, if appropriate, For example, if no radio contact can be made to the cloud, directly process at least rudimentary, so that in principle the user is issued a warning. If no radio contact between the vehicle and the cloud can be produced, it is possible in the event that, for example, at a corresponding roadside of the road currently being traveled by the vehicle, reading devices are arranged at respective interpolation points, preferably from the cloud Nevertheless, data can be obtained via the communication path Cloud -> Base 1 -> ... -> Base n -> Reader (Vehicle), since the bases or the readers arranged there are, for example, interconnected via a LAN, as described above and an ultimately close enough to the vehicle currently arranged base can ultimately exchange data via radio waves with the vehicle or with the reader disposed therein. In the central data acquisition unit, certain possibly periodic repetitions of certain behavior patterns of certain animals can be deposited, which arise, for example, the fact that these certain animals at certain annual or times of the day in certain regions, for example, to hunt. It can also be expected or predicted a game change on certain roads. A vehicle, in particular a motor vehicle, which travels a road running through one of these specific regions, may be radio-readmitted by a reader disposed therein, radio waves of sufficient range transmitted by the respective animals or those arranged on them, preferably RFID chips, and the associated data to be warned.

In the context of the present disclosure, a "communicative connection" is understood to be any connection via which data can be exchanged between the corresponding connection participants. This involves the exchange of electronic data by electronic means.

A reading device arranged at a support point, for example at a roadside, can exchange data directly with a reading device arranged in a vehicle, for example via radio waves, since both reading devices are active units. which can both receive data and send out data. Alternatively or additionally, it is also conceivable that the readers at respective bases, since they are usually permanently located, are connected to a fixed network and can exchange data about it. As the vehicle is usually not connected to the fixed network as a generally mobile unit, the reading device of the vehicle can alternatively exchange data via a mobile radio network. If data is now to be exchanged between a reading device at a fixed base and the reading device in the vehicle, this can be done indirectly via the cloud and the mobile radio network in addition to the direct exchange via radio waves. Is the vehicle in a "radio hole", ie it can not exchange data over the mobile network and therefore receive no data from the cloud, so it is possible, as far as the vehicle was detected by a arranged at a fixed base reader and above it in the cloud As is known in the relevant environment, the vehicle from the cloud, in turn, indirectly receives data from the cloud indirectly via one of the readers arranged at the street passed by the vehicle. Since the example. At a roadside arranged bases with the corresponding readers are preferably arranged at fixed distances from each other, it is known direction and speed of the vehicle, which the cloud is transmitted as information as soon as the vehicle with its reader within reach of one Readers at the bases come, calculable for the computing unit located in the cloud, when the warning of a potential danger must be issued, so that the vehicle receives this warning on the respective readers at the bases in time. It is also conceivable to install small mobile-capable systems, such as. Pico cells with very low efficiency, which can be connected to the bases, for example via LAN, and about a WLAN / WiFi communication with the vehicle in potentially critical To realize situations. If the vehicle is in an environment without support points with readers arranged thereon, the communication takes place directly between the reading device of the vehicle and the passive transponders on the possibly moving objects in the surroundings, those of the respective objects emitted feedback with the properties of the respective object are returned. In addition to further processing of the data by the arithmetic unit located in the cloud, a local arithmetic unit could also be arranged in the vehicle itself, which processes the data at least rudimentarily in a timely manner and possibly outputs a warning.

According to a further embodiment of the system according to the invention, the arithmetic unit is adapted to calculate on the basis of the data transmitted by the transponder, if the at least temporarily imperceptible moving object in the vehicle to pass or pass Environment is how far away the object from the vehicle is and in which direction the object is moving as fast relative to the vehicle.

In a further embodiment, the system according to the invention comprises a plurality of readers, which are arranged on correspondingly a plurality of support points, wherein the support points are arranged along a route passed or to be passed by the vehicle, in particular at regular intervals and in particular fixed. As a result, reliable data transmission can be ensured by objects located in the environment and each equipped with a passive transponder, such as an RFID chip. In this case, only the transponder moves between the respective reading device and the respective transponder, so that an approaching of a respective object to one of these interpolation points can be located very reliably by the fixed position of the respective reading device and its associated constant range of the radio waves emitted by it.

According to a further embodiment of the system according to the invention, it is conceivable, as already mentioned above, that the respective readers arranged at the interpolation points are able to conduct a communication via the radio network or mobile network and / or the fixed network or via this data receive and / or send. In particular, a communication with the cloud or the computing unit implemented therein is realized. As a result, the respective readers can also receive data on sources of danger which are known to the computing unit in the cloud, but outside the range of the radio waves emitted by the readers, via the communication network mobile network -> fixed network (LAN) and ultimately to the reader in the Vehicle via radio waves or over the mobile network are transmitted in good time and so communicated to the user. As a result, potential dangers could, for example, be made visible behind a curve. By additional use of the mobile network, a variety of transponder reflections can be recorded and possibly evaluated.

According to a further embodiment of the system according to the invention, the system according to the invention further comprises an output unit, such as a display and / or an audio unit, which is designed to display the evaluated data to a user of the vehicle. With the aid of a display, the evaluated data can be graphically displayed to the user. By means of an audio unit, the evaluated data can be displayed to the user either alternatively or additionally acoustically.

Depending on the configuration of the reader associated with the vehicle, it is also conceivable, as already mentioned above, that the evaluation of the data takes place directly in the reading device or in a computing unit connected to the reading device and locally arranged in the vehicle, or if a measure of a vehicle-related system is triggered can be. As a result, forecasts, warnings, etc. based on the data transmitted by a respective transponder, such as, for example, from an RFID chip, can also be locally calculated directly and output to the user of the vehicle, such as to occupants of a motor vehicle.

In a further embodiment, the reading device is designed to call the arithmetic unit by means of an application (app) installed on the reading device or on another device communicatingly connected to the reading device in order to obtain data with the arithmetic unit, in particular the central, ie exchange the organizationally superordinate arithmetic unit stored in a cloud.

In an urban environment, an arrangement of bases equipped with respective readers makes sense at regular intervals along roads and / or paths, since a comparatively high volume of traffic is to be expected here and therefore such an installation is worthwhile. In a more rural environment, it may be more convenient to locate the respective readers on or in the respective vehicles that pass through the rural environment, since traffic is comparatively low and an array of readers outside the vehicle, i. along their respective roads, is more difficult to judge by their meaningfulness.

Furthermore, the arithmetic unit can be configured to indicate on the basis of the specific behavior patterns at least one route on which the vehicle can pass the environment to be passed relatively danger-free. The inventively provided arrangement or implementation of a central processing unit in a cloud, which is designed to record, process and evaluate object-specific data of objects and vehicle-specific data of vehicles and created movement pattern, in particular the objects, not only in combination with created movement patterns of the vehicle for calculating a potential risk for a respective vehicle, but this created movement pattern of objects preferably together with other parameters such as time, ie time of day, season, etc., weather, ie rain, snow, etc. in a central data acquisition unit or store in a database included, it is possible to implement an intelligent data processing system. The thus realized intelligent data processing system is capable of continuously updating the database by continuously recording and storing motion patterns of objects together with the aforementioned parameters, any vehicle having a particular environment at a particular day and / or season in certain weather if this environment happens or intends to pass through this environment, it is advisable to make a report about a danger of a collision with the environment and of the particular time of the day and / or the season and / or weather View vehicle.

The intelligent processing system is a learning system, which is trained in more and more detail on the occurrence of certain scenarios by the continuous recording and processing of the object-specific and vehicle-specific data.

Each object and vehicle, each equipped with the aforementioned utensils, such as transponder or reader, can be detected by the intelligent processing system or receive from this as a vehicle or as its user appropriate messages / warnings.

Any vehicle passing a particular environment and equipped with a reader provided in accordance with the present invention will help to enrich the database with up-to-date data and movement patterns, thereby updating the database, benefitting a vehicle passing through that particular environment in time thereby existing for this particular environment and depending on the frequency with which this particular environment is passed by vehicles according to the invention, relatively current data or movement patterns can be provided. The tighter the network of readers and / or reader-equipped interpolation points and objects equipped with transponders, the lower the risk for a vehicle to enter an environment where the intelligent processing system or computing unit fails to report a potential of an object can be given outgoing danger.

According to yet another embodiment of the system according to the invention, the arithmetic unit is in communicative connection with a unit Output of other traffic information, whereby the specified by the computing unit route can also be optimized in terms of other traffic information. The unit for outputting other traffic information may, for example, be a unit which records congestion reports, construction sites, a restricted width and load capacity of certain sections, etc., on respective lanes and provides this information. A suitable merging of this information can serve the user to find a suitable route for him or it can be made by the merge the user automatically a suitable route proposal.

Furthermore, the present invention relates to a method for preventing a collision of a vehicle with an at least temporarily unnoticeable for a user of the vehicle unnoticeable moving object, wherein an embodiment of the system described above is used to carry out the method.

• Anordnen mindestens eines Lesegeräts an dem Vehikel und/oder an mindestens einem mit dem Vehikel in kommunikativer Verbindung stehenden Stützpunkt,
• Aussenden hochfrequenter Radiowellen von dem mindestens einen Lesegerät in eine von dem Vehikel passierte und/oder zu passierende Umgebung,
• Empfangen von Radiowellen mit objektspezifischen Daten durch das Lesegerät, die durch einen an dem sich bewegenden Objekt angeordneten Transponder, wenn sich das Objekt in der von dem Vehikel passierten und/oder zu passierenden Umgebung befindet, in Reaktion auf die durch das Lesegerät ausgesendeten Radiowellen ausgesendet werden,
• Übermitteln der objektspezifischen Daten zusammen mit vehikelspezifischen Daten an eine in einer Cloud implementierte Recheneinheit, und
• Auswerten der übermittelten Daten mit Hilfe der von der Cloud umfassten und für das Lesegerät aufrufbaren Recheneinheit, indem auf Basis der Daten Verhaltens- bzw. Bewegungsmuster sowohl des Vehikels als auch des sich zumindest zeitweise für das Vehikel unbemerkbar bewegenden Objekts in der von dem Vehikel passierten bzw. zu passierenden Umgebung bestimmt und daraus eine potentielle Gefahr des sich zumindest zeitweise für das Vehikel unbemerkbar bewegenden Objekts für das Vehikel berechnet werden.

The method is designed for avoiding a collision of a vehicle with an object which at least temporarily goes unnoticeably for a user of the vehicle, the method having at least the following steps:

• Arranging at least one reading device on the vehicle and / or on at least one support point in communication with the vehicle,
• Emitting radiofrequency radio waves from the at least one reading device into an environment passed and / or to be passed by the vehicle,
• Receiving, by the reader, radio waves having object-specific data emitted by a transponder disposed on the moving object when the object is in the environment passed and / or to be passed by the vehicle in response to the radio waves emitted by the reader .
• Transmitting the object-specific data together with vehicle-specific data to a computing unit implemented in a cloud, and
• Evaluating the transmitted data with the help of the cloud included and callable for the reader processing unit by based on the data behavior or movement patterns of both the vehicle and at least temporarily unnoticeable for the vehicle moving object in the vehicle passed by or to the environment to be passed and from this a potential risk of the at least temporarily unnoticeable object for the vehicle moving object for the vehicle can be calculated.

In a further refinement of the method according to the invention, specific, in particular periodic repetitions of specific movement patterns of specific objects are stored in a data processing unit in communication with the arithmetic unit, with the arithmetic unit in combination with the central data acquisition unit movement patterns of a certain type of objects that are predominantly in certain regions are created and, if necessary, the vehicle, in particular during or before passing through the vehicle, and once the vehicle is detected by the emission of radio waves by its reader as being in or near the particular region, be provided automatically and preventively.

The evaluated data are stored in a further embodiment of the method at least for a predeterminable time window and / or until overwriting with other data and provided for further analysis.

Through an inventive use of cloud computing for data acquisition, ie storage, and data evaluation, each entity with the appropriate equipment, ie a suitable reader, which has access to the cloud, be supplied with data that a user of a vehicle, in or on which the reading device is arranged, facilitates passing through or passing through an environment. It is irrelevant where The vehicle is located, because the central data acquisition data from all possible areas and regions or environments detected and processed and on request, ie as soon as the vehicle is detected by the emission of radio waves through its reader as being in a particular region / environment , made available. If data of a specific area or a specific environment has already been transmitted and evaluated and stored by a previous user or by readers arranged on a respective route located in the area / environment, then a user of this area or this environment happens to benefit from these already deposited data. The data already stored, for example regarding the behavior of certain animals occurring in the area or the environment, are continuously updated as soon as new data is transmitted by respective readers which are permanently or temporarily located in the area or in the surroundings ,

As a result, hitherto largely unknown areas or environments can be developed and therefore safer for the areas or environments passing vehicles can be made.

Further advantages and embodiments of the invention will become apparent from the description and the accompanying drawings. It is understood that the features mentioned above and those yet to be explained below can be used not only in the particular combination indicated, but also in other combinations or in isolation, without departing from the scope of the present invention.

FIG. 1 shows a road 10 in an environment 1. On the road 10 drives a vehicle 11, here a motor vehicle. In the motor vehicle 11 is a (here oversized large) read device 12 is arranged. The reader 12 sends, usually at regular intervals, high-frequency radio waves in the environment 1 from. The radio waves have a certain range, as indicated by the surrounding the motor vehicle 11 ellipse 13. Located at the time of broadcasting the radio waves within reach, ie within the ellipse an object that is equipped with a transponder, in particular with an RFID chip, so the radio waves emitted by the reader reach the transponder and are from him or taken from an antenna included by him. In response to the recorded radio waves, the transponder itself emits radio waves, and the radio waves send certain data concerning the object. This object-specific data is again recorded by the reader 12. The reader 12 sends the data along with vehicle-specific data for storage and further processing usually via a mobile network to a computing unit located in a cloud. The central processing unit located there calculates on the basis of the transmitted data, for example, how far the object is from the motor vehicle 11, how fast the object moves in which direction relative to the motor vehicle 11. On the basis of the object-specific data and the vehicle-specific data, movement patterns of both the object and the motor vehicle 11 are determined. It can now Furthermore, derived or calculated, which danger from the object for the motor vehicle 11 or for its occupants emanates and whether there is a potential risk of a collision, if the motor vehicle does not change its route guidance. The evaluated data are displayed to a user, in particular a driver of the motor vehicle 11 in a suitable manner, for example on a display arranged in the motor vehicle and / or by an audio output from an audio output device arranged in the motor vehicle, such as a loudspeaker. In this case, the driver can either be signaled only the potential danger or in addition an alternative route to be called, which he can take to avoid an imminent collision with the object.

FIG. 2 shows a schematic representation of the in FIG. 1 illustrated embodiment of the inventive system alternatively or additionally to be provided measure to avoid according to the invention possible collisions of a motor vehicle with an object. On the road 10 in turn is a motor vehicle 11. The road 10 in turn passes through an environment 1. In the embodiment shown here now support points are provided along the road 10 at regular intervals, on each of which a reader 14 is arranged. The respective reader 14 is just like the reader 12 off FIG. 1 suitable for transmitting high frequency radio waves. Since a plurality of readers 14 are located along the road 10, radio waves are also emitted from correspondingly many places, as indicated by the respective circles or ellipses 15. The readers 14 are arranged so that their respective ranges overlap such that a quasi-continuous band results, arrive in the radio waves of at least one of the readers 14. If an object equipped with a transponder is now located in the band, the transponder itself transmits radio waves and associated data regarding the object in response to the received radio waves. These data are then recorded by at least one of the readers 14, namely exactly the reader (s) in whose range the object is currently located, ie when transmitting the data. It is also from at least one the reading device 14 detects the vehicle 11 itself due to the radio waves emitted by its reading device 12, whereby the vehicle 11 or its reading device 12 transmits vehicle-specific data, ie the data characterizing the vehicle. All data is then sent by the respective receiving reader 14 for storage and further processing to a central processing unit located in a cloud. The central processing unit located there calculates on the basis of the transmitted data, for example, how far the object is from the motor vehicle 11, how fast the object moves in which direction relative to the motor vehicle 11. From this, it is now also possible to deduce or calculate which danger emanates from the object for the motor vehicle 11 or for its occupants and whether there is a potential risk of a collision if the motor vehicle does not change its route guidance. The evaluated data are displayed to a user, in particular a driver of the motor vehicle 11 in a suitable manner, for example on a display arranged in the motor vehicle and / or by an audio output from an audio output device arranged in the motor vehicle, such as a loudspeaker. For this, the display or the audio output device must be in communicative connection with the cloud, so that data can be received from there. The display or the audio unit can also communicate with the reading device 12 and / or the reading devices 14 in a communicative connection, for example wirelessly via Bluetooth or the like, and can be indirectly connected to the cloud via it. In this case, the driver can either be signaled only the potential danger or in addition an alternative route to be called, which he can take to avoid an imminent collision with the object. The readers 14 can be interconnected via the landline, ie, for example. Via a LAN and exchange data or forward. The respective readers 14 may also be connected via the fixed network directly or via a mobile network to the cloud. The vehicle 11 or the reading device 12 arranged therein can usually be connected to the cloud via a mobile radio network and via the reception and emission of radio waves with the respective reading devices 14 in a communicative connection. This results in a number of possible communication paths over which the user of the vehicle 11 ultimately data concerning a potential danger even if the vehicle 11 is temporarily in a "radio hole".
