Description
3. Beschreibung Elektronische Abstandsautomatik für Fahrzeuge.3. Description of electronic automatic distance control for vehicles.
5.1 Baugruppen Echolot, Geschwindigkeitsmelder,, Kleinkomputer, Motordrehzahlregler, Bremsgerät.5.1 Assemblies echo sounder, speed sensor, small computer, engine speed controller, Braking device.
3.2 Einbauaufteilung Das Echolot wird im vorderen Fahrzeugteil, ohne Abstrahlbehinderung nach vorn, in Fahrzeugachse zur Fahrtrichtung montiert.3.2 Installation layout The echo sounder is in the front part of the vehicle, without Radiation obstruction to the front, mounted in the vehicle axis to the direction of travel.
Der Geschwindigkeitsmelder wird als Impulsgeber zwischen der Tachometerwelle und dem Tachometer montiert. The speed sensor acts as a pulse generator between the speedometer shaft and the speedometer mounted.
Der Kleinkomputer wird als elektronischer Rechner im Fahrzeug montiert. The small computer is installed in the vehicle as an electronic computer.
Der Motordrehzahlregler wird zwischen dem Fahrpedal und dem Motor montiert. The engine speed controller is located between the accelerator pedal and the engine assembled.
Das Bremsgerät wird direkt mit dem Hauptbremszylinder gekuppelt. The braking device is coupled directly to the master brake cylinder.
5.5 Arbeitsweise Der zwischen der Tachometerwelle und dem Tachometer montierte Geschwindigkeitsmelder sendet zum elektronischen Kleinkomputer laufend Stromimpulse. Die Impulse werden ähnlich wie die im Zündverteiler erzeugt (Unterbrecherkontakte).5.5 How it works The one between the speedometer shaft and the speedometer mounted speed sensor sends to the electronic Small computer continuous current pulses. The impulses are generated similarly to those in the distributor (Breaker contacts).
Die im Komputer eingehenden Impulse werden a) zur Zeit-Weg-Messung gespeichert und b) verstärkt zum Echolot weitergeleitet. Der im Echolot durch den Impuls erregte Schallsender sendet einen Taststrahl zum vorausfahrenden Fahrzeug. Das vorausfahrende Fahrzeug reflektiert diesen Taststrahl zum Echolot zurück. Der im Echolot eingebaute Schall empfänger empfängt diesen Taststrahl und gibt ihn als Impuls an den Komputer weiter. Der Komputer errechnet aus den Werten von Impulsausgang und -eingang den Sicherheitsabstand zum vorausfahrenden Fahrzeug.The impulses arriving in the computer become a) time-distance measurement stored and b) forwarded amplified to the echo sounder. The one in the echo sounder through the Impulse-excited sound transmitters send a probe beam to the vehicle in front. The vehicle in front reflects this probe beam back to the echo sounder. Of the The sound receiver built into the echo sounder receives this probe beam and transmits it as a Impulse to the computer. The computer calculates from the values of the pulse output and input the safety distance to the vehicle in front.
Der Sicherheitsabstand wird elektronisch mit der Zeit-Weg-Mesaung abgeglichen. Sollte nun der errechnete Sicherheitsabstand zu gering werden, erfolgt aus dem elektronischen Schaltkreis eine Reaktion in Form eines Steuerstromes.The safety distance is determined electronically with the time-distance measurement matched. If the calculated safety distance is too small, it takes place a reaction in the form of a control current from the electronic circuit.
Dieser Steuerstrom erregt einen elektrischen Drehzahlregler, der unabhängig vom Fahrpedal die Motordrehzahl, und damit die Fahrgeschwindigkeit, regelt.This control current energizes an electrical speed controller that is independent regulates the engine speed, and thus the driving speed, from the accelerator pedal.
Sollte der Sicherheitsabstand sich zu schnell verringern, so wird über den elektronischen Drehzahlregler ein weiterer Steuerstrom ausgelöst.Should the safety distance decrease too quickly, then Another control current is triggered via the electronic speed controller.
Dieser Steuerstrom betätigt einen magnetischen Bremsanker am Hauptbremszylinder oder ein elektronischen Steuerventil für eine Servo-Luft-Unterdruckbremse.This control current actuates a magnetic brake armature on the master brake cylinder or an electronic control valve for a servo air vacuum brake.
Nachdem das Fahrzeug zum vorausfahrenden Fahrzeug auf einen zuverlässigen Sicherheitsabstand einreguliert wurde, wird vom Komputer der Steuerstrom zum Motordrehzahlregler zurückgeregelt.After the vehicle to the vehicle in front on a reliable Safety distance has been adjusted, the computer sends the control current to the engine speed controller regulated back.
Dieser Vorgang, Geschwindigkeitsmessen, Sicherheitsabstandmessen und mittels Steuerstrom über Motordrehzahlregler und Bremsgerät die gefahrene Geschwindigkeit regulieren, erfolgt in ununterbrochener Reihenfolge im Rhythmus des Impulsgebers vom Geschwindigkeitsmelder.This process, speed measurement, safety distance measurement and the driven speed by means of control current via the engine speed controller and braking device regulate, takes place in uninterrupted sequence in the rhythm of the pulse generator from the speed sensor.
.4 Sicherung der Anlage Die Absicherung der Anlage gegenüber anderen eleRtronischen Signalen von anderen Fahrzeugen wird dadurch gewährleistet, daß, jede Anlage nur ihre eigene Tonmodulation verarbeitet; ahnlich einem Sicherheitsschloß mit mehreren Zuhaltungen (Zuhaltungen = Tonmodulation)..4 Securing the system Securing the system against others Electronic signals from other vehicles are guaranteed by the fact that each system only processes its own tone modulation; similar to a security lock with several tumblers (tumblers = tone modulation).
1. Titel (Technische Bezeichnung) Elektronische Abstandsautomatik.1. Title (technical name) Electronic distance control.
1.1 Anwendungsgebiet Die Erfindung betrifft eine elektronische Abstandsautomatik für Fahrzeuge zur Vermeidung von Kollisionen.1.1 Field of application The invention relates to an electronic automatic distance control for vehicles to avoid collisions.
1.2 Zweck Im derzeitigen Straßenverkehr ist es unbedingt erforderlich, einen zuverlässigen Sicherheitsabstand zum vorausfahrenden Fahrzeug einzuhalten.1.2 Purpose In current road traffic, it is essential to Maintain a reliable safety distance from the vehicle in front.
Z.Zt. wird das Abstandhalten von Fahrzeugen untereinander im Straßenverkehr von einem Fahrzeugführer (Menschen) gesteuert. Die Reaktion des Fahrzeugführers wird jedoch von der psychischen Konzentration, Witterungserscheinungen, der geographischen Lage und vielem mehr beeinflußt. Currently is keeping vehicles at a distance from one another in traffic controlled by a driver (human). The driver's reaction However, it depends on the psychological concentration, the weather, the geographical Location and much more.
1.3 Stand der Technik Es ist bekannt, daß die Taststrahlortung mittels Radar oder Echolot zur Ermittlung des eigenen oder eines fremden Standortes dient.1.3 Prior art It is known that the scanning beam location by means of Radar or echo sounder is used to determine one's own or someone else's location.
Das Hauptverfahren ist das Rückstrahlprinzip (Deutsches Patent Hülsmeyer, 1904). Ein pulsmodulierter Sender speist eine scharf bündelnde Richtantenne, deren Strahlenkeule auf das Ziel ausgerichtet ist. Ein Teil der Sendeenergie wird von der Oberfläche des Ziels, z.B. Fahrzeuwgrückwand oder sonstiges Hindernis, reflektiert und kehrt zur Sendeantenne, die jetzt als Empfangsantenne benutzt wird, zurück. Der Sendeimpuls und der etwas später eintCeffende Reflexionsimpuls werden im zeitlichen Abstand t gemessen. The main process is the reflection principle (German patent Hülsmeyer, 1904). A pulse-modulated transmitter feeds a sharply focused directional antenna, whose Beam is aimed at the target. Part of the transmission energy will reflected from the surface of the target, e.g. the rear wall of the vehicle or other obstacle and returns to the transmitting antenna, which is now used as the receiving antenna. The transmission pulse and the reflection pulse arriving a little later are temporal Distance t measured.
Bekannt ist, daß die See- und Luftschiffahrt ohne Radar und Echolot nicht mehr auskommt. Landfahrzeuge.werden Jedoch seit der Erfingung des Rades durch das menschliche Auge, über das Gehirn, mit der daraus resultierenden Reflexbewegung der Arm- und Beirmuskeln navigiert. It is known that the sea and air navigation without radar and echo sounder no longer works. Land vehicles, however, have been through since the invention of the wheel the human eye, via the brain, with the resulting reflex movement the arm and arm muscles navigated.
1.31 Kritik am Stand der Technik Bedingt durch die ständig wachsende Zahl von Fahrzeugen, kraftvolleren und schnelleren Fahrzeugtypen, psychischen Streß der Fahrzeugführer und vielem mehr im Straßenverkehr, ist eine Zunahme der täglichen Kollisionen ohne wesentliche Beeinflussung durch schnell reagierende Zusatzeinrichtungen nicht mehr vermeidbar.1.31 Criticism of the state of the art Due to the constantly growing Number of vehicles, more powerful and faster vehicle types, psychological stress the driver, and much more in road traffic, is increasing daily Collisions without significant influence from quickly reacting additional devices no longer avoidable.
Neuzulassungszahlen von Fahrzeugen, Unfallstatistiken und steigende Versicherungsprämien werden täglich in den Tageszeitungen und Fachzeitschriften bekanntgegeben. New vehicle registrations, accident statistics and increasing Insurance premiums are published daily in the newspapers and specialist magazines announced.
2. Aufgabe Der Erfindung liegt die Aufgabe zugrunde, die Vielzahl der Verkehrsunfälle durch zu dichtes Auffahren im Straßenverkehr zu mindern.2. Task The invention is based on the task of the multitude to reduce traffic accidents caused by driving up too close in traffic.
2.1 Lösung Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß dic elektronische Abstandsautomatik - von geistigen und körperlichen Reaktionen des Fahrzeugführers unabhängig -einen zuverlässigen Sicherheitsabstand einhält.2.1 Solution This object is achieved according to the invention in that dic electronic automatic distance control - of mental and physical reactions independently of the vehicle driver - maintain a reliable safety distance.
2.2 Erzielbare Vorteile Die mit der Erfindung erzielten Vorteile bestehen insbesondere darin, daß die im Straßenverkehr durch Auffahren verursachten Verkehrsunfälle, die den überwiegenden Teil aller Verkehrsunfälle in Anspruch nehmen, stark reduziert werden. Volksvermögen wird geschützt. Haftpflichtprämien können durch kleineres Risiko gesenkt werden.2.2 Achievable Advantages The advantages achieved with the invention exist in particular that the traffic accidents caused by collision in road traffic, which make up the majority of all traffic accidents, greatly reduced will. National wealth is protected. Liability premiums can be reduced by smaller Risk to be reduced.
