Abstract

The system for measuring spacing distances between vehicles and for selective transmission of information to vehicles and to traffic signals and beacons, determines the spacing by emitting electromagnetic radiation and receiving the back-scattering in at least one channel.The transmission and reception arrangement used for measurement of spacing distances is utilised for transmission of information.Measurement of spacing distances between motor vehicles or differential speed is performed using optical- or HF pulses.

Description

Stand der TechnikState of the art

Zur reinen Abstandsmessung oder Differenzgeschwindigkeitsmessung mit Licht- oder Hochfrequenzimpulsen sind eine Reihe von Verfahren wie z. B. DE 36 40 449 C1, DE 41 27 168 C2 oder DE 30 20 996 bekannt.For pure distance measurement or differential speed measurement with light or Radio frequency pulses are a number of methods such as e.g. B. DE 36 40 449 C1, DE 41 27 168 C2 or DE 30 20 996 known.

Für die Informationsübertragung von Fahrzeug zu Fahrzeug und zu Verkehrsleitsystemen sind Funk, Telefon, Signalbrücken und Infrarot-Sende- und Empfangseinrichtungen be­ kannt.For the transmission of information from vehicle to vehicle and to traffic management systems are radio, telephone, signal bridges and infrared transmitters and receivers knows.

Alle diese Systeme haben den Nachteil, daß sie zur Selektierung der Teilnehmer entwe­ der eine Kodierung benötigen oder nur im extremen Nahbereich von einigen Metern funk­ tionieren.All these systems have the disadvantage that they either escape for the selection of the participants who require coding or only radio in the extremely close range of a few meters function.

Vorliegende Erfindung nützt das Abstandsmeßsystem zugleich zur Informationsübertra­ gung zwischen Fahrzeugen und auch zu Verkehrsschildern und Baken und selektiert die Information durch die gleichzeitige Verarbeitung der gemessenen Entfernung zum Infor­ mationssender und -empfänger.The present invention also uses the distance measuring system for information transfer between vehicles and also traffic signs and beacons and selects them Information through the simultaneous processing of the measured distance to the information Mation transmitter and receiver.

Zu diesem Zweck besteht gemäß Fig. 1 das Gesamtsystem aus Empfangs- und Sende­ optik (101), aus der Empfangseinheit (102) bestehend aus mehreren Kanälen, der Sende­ einheit (103) ebenfalls mit mehreren Kanälen. Diese beiden Einheiten (102, 103) sind mit dem Signalprozessor (104) und seiner Taktsteuerung verbunden. Dem System wird eine Einheit für Informationsübertragung und -empfang (105) hinzugefügt, die direkt mit dem Auswerterechner (106) und damit mit dem Signalprozessor (104) verbunden oder inte­ griert ist.For this purpose, according to FIG. 1, the overall system consists of receiving and transmitting optics ( 101 ), of the receiving unit ( 102 ) consisting of several channels, the transmitting unit ( 103 ) also having several channels. These two units ( 102, 103 ) are connected to the signal processor ( 104 ) and its clock control. A system for information transmission and reception ( 105 ) is added, which is directly connected to or integrated with the evaluation computer ( 106 ) and thus with the signal processor ( 104 ).

Das System hat eine Versorgung (107) und eine Schnittstelle zum Fahrzeug (108). Das System kann mit Lichtquellen oder Hochfrequenzstrahlung arbeiten.The system has a supply ( 107 ) and an interface to the vehicle ( 108 ). The system can work with light sources or high frequency radiation.

Bei der Entfernungsmessung werden je Kanal mehrere Impulse ausgesendet die bei der erfindungsgemäßen Informationsübertragung wie folgt verwendet werden:When measuring distance, several pulses are sent out per channel Information transmission according to the invention can be used as follows:

Zum einen kann die Entfernungsmessung getrennt von der Informationsübertragung erfol­ gen. Entsprechend Fig. 2 wird ein Impulszug 201 ausgesandt der als Impulszug 202 empfangen wird. Nach diesem Impulszug wird mit dem gleichen Sender die Information, z. B. durch zeitliche Kodierung der Pulse (203) übertragen und vom Partner-Kfz oder -Sig­ nal oder -Informationssystem die Information als kodierte Impulsgruppe (204) abgegeben und durch das System empfangen. Durch die Korrelation dieser Information mit der Ent­ fernungsmessung und dem jeweiligen Sende-Empfangskanal kann diese Information ei­ nem bestimmten Partner zugeordnet werden.On the one hand, the distance measurement can be carried out separately from the information transmission. According to FIG. 2, a pulse train 201 is sent which is received as a pulse train 202 . After this pulse train with the same transmitter, the information such. B. transmitted by time coding of the pulses ( 203 ) and the partner vehicle or signal or information system, the information as a coded pulse group ( 204 ) and received by the system. By correlating this information with the distance measurement and the respective send / receive channel, this information can be assigned to a specific partner.

Zum anderen ist es möglich die Sendeimpulsgruppe, die der Entfernungsmessung dient, entsprechend Fig. 3 direkt im Zeitkodierverfahren so zu gestalten, daß Entfernungsmes­ sung und Informationsübertragung zugleich erfolgen.On the other hand, it is possible to design the transmission pulse group used for distance measurement according to FIG. 3 directly in the time coding method so that distance measurement and information transmission take place simultaneously.

Die Antwort des Partners erfolgt als Impulsgruppe (302) jeweils mit einer bekannten Zeit­ differenz (303) von z. B. 100 ns - 10 ps und ist damit eindeutig zuordenbar und vom Ab­ standsmeßsignal (304) unterscheidbar, da die Laufzeit durch die bekannte Entfernung ebenfalls durch die Halbierung der durch die Entfernungsmessung ermittelten Laufzeit (305) ausgeglichen werden kann.The partner's response is given as a pulse group ( 302 ) with a known time difference ( 303 ) of z. B. 100 ns - 10 ps and is thus clearly assignable and distinguishable from the distance measurement signal ( 304 ), since the transit time can also be compensated for by the known distance by halving the transit time ( 305 ) determined by the distance measurement.

Durch dieses Verfahren können mehrere Informationen aus unterschiedlichen Entfernun­ gen räumlich durch die Anordnung der Kanäle und abstandsmäßig durch die Entfernungs­ messung zugeordnet werden.This method allows multiple pieces of information to be moved from different distances ge spatially by the arrangement of the channels and spaced by the distance measurement can be assigned.

Dabei wird z. B. entsprechend Fig. 4 vom Fahrzeug (401) das System mit seinen 7 Kanä­ len (402a bis 402g) eingesetzt. Das Fahrzeug (403) hat den Abstand (4032) und befindet sich in den Kanälen (402f) und (402g). Seine Information an das Fahrzeug (401) setzt es mit dem Signal (4031) in Kanal (402g) ab. Das gleich gilt für das Fahrzeug (404) mit sei­ nem Abstand (4042) und seiner Information (4041) im Kanal (402d) und die Information aus dem Verkehrszeichen (405) mit seinem Abstand (4052) und seiner Information (4051) in Kanal (402a) und (402b). Damit sind alle Informationen eindeutig zuordenbar. Die Ko­ dierung der Information kann innerhalb der Entfernungsmessung mit Mehrfachpulsen in sehr kurzem Abstand von z. B. 10 ns erfolgen oder bei sequentieller Entfernungserfassung in einem entsprechenden Raster, bei dem keine oder wenig Mehrdeutigkeiten mit dem ei­ gentlichen Meßsignal auftreten.Here, for. B. according to Fig. 4 of the vehicle ( 401 ) the system with its 7 channels ( 402 a to 402 g). The vehicle ( 403 ) has the distance ( 4032 ) and is in the channels ( 402 f) and ( 402 g). It sends its information to the vehicle ( 401 ) with the signal ( 4031 ) in channel ( 402 g). The same applies to the vehicle ( 404 ) with its distance ( 4042 ) and its information ( 4041 ) in the channel ( 402 d) and the information from the traffic sign ( 405 ) with its distance ( 4052 ) and its information ( 4051 ) in Channel ( 402 a) and ( 402 b). This means that all information can be clearly assigned. The coding of the information can be within the distance measurement with multiple pulses in a very short distance from z. B. 10 ns or with sequential distance detection in a corresponding grid, in which little or no ambiguity with the egg yeast measurement signal occur.

In das System können auch reine Empfänger entsprechend Fig. 5 eingebunden werden die nur Empfangsoptik (501), Empfänger (502), Signalprozessor (503), Datenselektion (504), Fahrzeugschnittstelle (505) und Versorgung (506) enthalten. Der Abstand wird diesem reinen Empfangssystem durch den jeweiligen Sender mitgeteilt. Dieses System kann zur Aktivierung oder Vorbereitung von passiven Schutzmaßnahmen für Fahrzeuge und oder Insassen bei Front-, Seiten- oder Heckaufprall verwendet werden.Pure receivers according to FIG. 5 can also be integrated into the system which only contain the receiving optics ( 501 ), receiver ( 502 ), signal processor ( 503 ), data selection ( 504 ), vehicle interface ( 505 ) and supply ( 506 ). The distance is communicated to this pure reception system by the respective transmitter. This system can be used to activate or prepare passive protective measures for vehicles and or occupants in the event of a front, side or rear impact.

Darüber hinaus ist das System für die Beurteilung von Verkehrssituationen über informa­ tionsfähige Verkehrszeichen oder Baken geeignet.In addition, the system for assessing traffic situations is via informa suitable traffic signs or beacons.

Bei Einführung einer Straßenbenutzungsgebühr kann das erfindungsgemäße System auch zur Erfassung, Identifizierung und Kostenzuordnung verwendet werden.When introducing a road user fee, the system according to the invention can also used for recording, identification and cost allocation will.
