Abstract

The invention has the object of significantly reducing the risk of collision in ground transportation by continuously determining the distance to the other moving vehicles and their speed vectors. As a result, prompt warnings of risks of collisions can be given in the vehicle. The system detects a possible risk of collision by means of a computer from the speed vector of the vehicle and the optically measured movements of other vehicles. The optical measuring process constitutes a sequential viewing on the basis of an observation of light intensities in two batteries by tubes which are arranged in a star shape and have a narrow aperture. The time-dependent intensity distributions are evaluated by means of a computer and permit the necessary speed and distance determinations to be made.

Description

Gerät und Verfahreh aur. Verheidung. non Kollisionen im Landverkehr Beschreibung die Erfindung bezieht sich auf eine automatische Anzeige der Guschwindigkeitsvektoren anderer sich am Langverkehr betweiligender Objekte in t inem Fahrzeug, sowie die Estrapolation der beobachteton Geschwindigkeiten und der Eigengschwindigkei t des Fahrzeuges mit dem Ziel, oolentielle Kollisionen Rechtzeitig im vorhinein automatisch anzuzeigen. dies wird dadurch erreicht, daO auf dem landfahreug zwei Empfangssysteme fest installiert sind, ciic jewells aus mehreren geeignet angeordneten und gerichteten Empfängern für elektromagnetische oder akustische Signale bestehen. newcgt sich ein Objekt relativ zum Fahrzeug, so erreichen die von ihm ausgesandten Signale zu einer bestimmten Zeit nur einen oder wcnige der gerichteten Empfänger in den beiden mc fangssystemen. Im Fortschreiten der Zeit werden dann andere Emp ;Lnger angesprochen. die Signalfolge und die Intensitätsverteilungan werden aufgezeichnet und in einem Rechner derart unter Berücksichtigung der Geometrie der Emfänger verrechnet, daß eine Ancsage über den (die) Geschwindigkeitsvektor (en) den (der) Objekte (s) moglich ist. Die Selektivität der Empfänger sorgt dafür, daß Hintergrundssignale keinen störenden Einfluß haben, wenn das von dem bewegten Objekt ausgehende Signal ausreichend spezifisch ist. Es handelt sich also bei der Erkennung von Bewegungen um ein "sequentielles Sehen" im Genensatz zur Mustererkennung. Die einzelnen Empfänger sehen das Objekt zu verschiedenen Zeiten, der Rechner erlaubt es aus der zeitlichen Sequenz und den bebochteten Intensitäten den Verlauf der Geschwindigkeitsvektoren kontinuierlich zu registrieren, wodurch Extrapolationen auf zukunftige Geschwindigkeiten mit relative geringer Rechenleistung mägliche werden. Device and procedure. Avoidance. non collisions in land transport Description of the invention relates to an automatic display of speed vectors other objects involved in long-haul traffic in a t inem vehicle, as well as the Estrapolation of the observed speeds and the intrinsic speed of the Vehicle with the aim of automatic collisions in good time in advance to display. This is achieved by having two receiving systems on the road are permanently installed, ciic jewells from several suitably arranged and directed Receivers for electromagnetic or acoustic signals exist. newcgt itself an object relative to the vehicle, so the signals sent by it reach At a given time only one or a few of the targeted recipients in the two mc catch systems. As time progresses, other recipients are addressed for longer. the signal sequence and the intensity distribution an are recorded and combined into one Calculates the computer taking into account the geometry of the receiver that an announcement about the speed vector (s) of the object (s) is possible is. The selectivity of the receiver ensures that there are no background signals have a disturbing influence if the signal emanating from the moving object is sufficient is specific. The detection of movements is therefore "sequential" See "in the set of genes for pattern recognition. The individual recipients see the object at different times, the calculator allows it from the temporal sequence and the intensities observed the course of the velocity vectors continuously to register, making extrapolations to future speeds with relative low computing power will be possible.

Der Verktor der Eigengeschwindigkeit des fahrzeugs wird aus der Abtstung das lenkwinkels und der Linearen Geschwindigkeit ermittelt und eben alls dem Rechner zugeführt. Dadurch kann aus Estrapolationen der Geschwindigkeiten der beteiligton Objekte auf dfe Gefahr einer Kollision geschlossen werden. Der Rochner gibt aine geeignete Anzeige entweder an das Fahrzung unmltelbon oder an den Fahrzeugführer aus. The vector of the vehicle's own speed is derived from the calibration the steering angle and the linear speed are determined and everything to the computer fed. This can result in estrapolations of the speeds involved Objects be closed at the risk of a collision. The Rochner gives a suitable indication either to the vehicle or to the vehicle driver the end.

Die Crfindung steillt einen wesentilichen Schritt auf dem @ege zur Vermeidung von Zusammentößen dar, der angesichts der jetzt verfügbaren InformationsverarSeitungseazität in einem Fahrzeug begangen werden kann. Es handelt sich um (in Verfahren und Gerät in dem deine eigentliche Mustererkennung Urfolgen muß, die technisch noch sehr schwierig ist. fine beispielhafte Anordnung zeigt die Abbildung 1 Hier handelt es sich um ein optisch funktionierendes System, bei dem die Ob-Jekte mit einem zweifardigen, vertikalen streifon markiert sind und die mit hoch selektiven Filtern ausgerüsteten gerichteten Photoempfänger nur lichtsignale, die von den 5 treifen ausgehen, registraieren. Die Photoempfänger sind am Lnde eines relative langen Rohres angeordnet, sodaß sie den Streifen jeweils nur sehr kurz"sehen". Die eintreffenden Signale, die zeitliche Verteilung, die Daten zur Eigengeschwindigkeit des Fahrzeugs und zu seiner Richtung werden von einem Rechenprogramm bcrrbeitet.The process of finding is an essential step on the way Avoiding clashes, given the information processing activity that is now available can be committed in a vehicle. It is (in procedure and device in which your actual pattern recognition has to follow, which is technically very difficult is. Figure 1 shows an example of an arrangement an optically functioning system in which the objects with a two-fold, vertical stripes are marked and those equipped with highly selective filters Directional photoreceiver only register light signals emanating from the 5 strips. The photoreceivers are arranged at the end of a relatively long tube so that they "see" the strip only very briefly. The incoming signals, the temporal Distribution, the data on the vehicle's own speed and its direction are processed by a computer program.
