Abstract

The traffic light system has a connection to an inductive loop antenna that generates an output to switch off the engine and then effect a restart when the lights change. The vehicle has a magnetic disc (a) on a wheel that maintains an induced signal in a coil (b) coupled to a relay (1). When the vehicles ceases to move the relay (1) responds and the ignition circuit relay (2) is blocked. When the lights change to green the starter is enabled via the generator and the engine is restarted. ADVANTAGE - Protects against unnecessary engine emissions. Saves fuel.

Description

Die Erfindung betrifft eine Schaltvorrichtung für den auto­ matischen Abstell- und Anlaßvorgang von Fahrzeugmotoren vor Verkehrsregelungs-Systemen. Es soll erreicht werden, daß aus Gründen der Reinerhaltung der Luft und/oder der Kraftstoffersparnis der Abstellvorgang in Verbindung mit dem Verkehrsregelungs-System nicht vom Willen des Fahrzeug­ lenkers abhängt, sondern durch diese Schaltvorrichtung auto­ matisch erfolgt. Desgleichen soll die Wiederinbetriebsetzung des Antriebsaggregates selbstätig, d. h. ohne Zutun des Fahrzeuglenkers geschehen.The invention relates to a switching device for the car Matic switching off and starting of vehicle engines in front of traffic control systems. It should be achieved that for the sake of keeping the air clean and / or Fuel saving the parking process in connection with the Traffic control system not by the will of the vehicle depends on the handlebar, but through this switching device auto is done mathematically. The same applies to the restart the drive unit automatically, d. H. without doing anything Vehicle drivers happen.

Es sind Verkehrsregelungs-Systeme (im folgenden Ampeln genannt) bekannt, bei denen neben der Lichtschaltung rot/ gelb/grün eine zusätzliche Anzeige "An und "Aus" die jeweils demnächst erfolgende Umschaltung anzeigt und dadurch der Fahrzeuglenker zu entsprechenden Maßnahmen in seinem Fahrzeug angehalten wird. Da es sich nur um Empfehlungen handelt, wird dieser Anzeige nur mangelhaft Folge geleistet, weilThere are traffic control systems (in the following traffic lights known), in which in addition to the light switch red / yellow / green an additional display "On and" Off "the indicates the next switchover and thereby the driver to take appropriate measures in his Vehicle is stopped. Since these are just recommendations acts, this notification is poorly followed, because

  • 1. der Fahrzeuglenker zwei Tätigkeiten, nämlich abstellen und anlassen vornehmen muß, was die Bequemlichkeit in der Regel verhindert,1. the vehicle driver has two activities, namely switching off and tempering must do whatever the convenience usually prevents
  • 2. er bei einer längeren Reihe haltender Fahrzeuge die Ampel, z. B. in einer Kurve oder hinter einem hohen Nutzfahrzeug, nicht sieht.2. he the in a long line of vehicles Traffic light, e.g. B. in a curve or behind a high Commercial vehicle, does not see.

Der Erfindung liegt die Aufgabe zugrunde, die Willkür des Fahrzeuglenkers auszuschalten. Es soll erreicht werden, in Verbindung mit der Ampel-Anzeige den Abstell- und Anlaßvorgang für jedes Fahrzeug in dem dem Verkehrsfluß dienenden kürzesten Zeitraum automatisch zu steuern, um zur Reinerhaltung der Luft beizutragen bzw. die Betriebsstoff­ ersparnis herbeizuführen.The invention is based, the arbitrariness of the task Turn off vehicle drivers. It should be achieved in connection with the traffic light display the parking and Starting process for each vehicle in the traffic flow serving to control the shortest period of time Contributing to keeping the air clean or the fuel to bring about savings.

Die Erfindung ist in drei Zeichnungen dargestellt und wird im folgenden näher beschrieben:
Ampelseitig wird durch die Phasen-Schaltung rot/gelb/ grün ein bei der Ampel befindlicher Schalter A betätigt, welcher mit Beginn der Ampelstellung "rot" einen Strom einer bestimmten Frequenz in ein aus mehreren Segmenten bestehendes Kabel schickt (Abb. 1). Die Länge der Segmente wird durch ein Mehrfaches einer durchschnittlichen Fahrzeuglänge bestimmt und jedes Segment in Form einer Induktionsschleife ausgebildet. Um das Abstellen des Motors beim Sprung der Ampel auf gelb/grün zu verhindern (dem das Wiederanlassen unverzüglich folgen müßte), ist die Schaltung der Abstell­ frequenz mit einem Zeitmesser verbunden, der vor dem Er­ löschen des Zeichens "rot" in einstellbarem Abstand die Aus­ sendung der Abstellfrequenz beendet (Abb. 2).The invention is illustrated in three drawings and is described in more detail below:
On the traffic light side, the phase switch red / yellow / green actuates a switch A located at the traffic light, which at the start of the traffic light position "red" sends a current of a certain frequency into a cable consisting of several segments ( Fig. 1). The length of the segments is determined by a multiple of an average vehicle length and each segment is designed in the form of an induction loop. In order to prevent the engine from turning off when the traffic light jumps to yellow / green (which should be followed immediately by restarting), the switching of the shutdown frequency is connected to a timer which, before deleting the "red" character, switches off at an adjustable interval transmission of the stop frequency ended ( Fig. 2).

Nach Wiederfreigabe des Verkehrs (Ampelstellung "grün") legt der Schalter A die (Anhalte-) auf eine (Anlaß-)Frequenz um, welche schrittweise in die einzelnen Segmente des Kabels geleitet wird. Die innerhalb eines Segmentes stehenden Fahr­ zeugmotoren werden gleichzeitig in Bewegung gesetzt, die (schaltbare) Abfolge der Schaltvorgänge der Anlaßfrequenz richtet sich nach der Länge der einzelnen Segmente.After the traffic is released again (traffic light position "green") the switch A the (stop) on a (start) frequency around, which gradually in the individual segments of the cable is directed. The driving within a segment Witness motors are set in motion at the same time (Switchable) sequence of switching operations of the starting frequency depends on the length of the individual segments.

Fahrzeugseitig wird ein Radantrieb mit einer in mehrere Ab­ schnitte unterteilte, sich mit dem Rad drehende Magnet­ scheibe a - Zeichnung 3 - verbunden, der mit dem Fahrzeug fest verbundene, auf einem gleichartigen Ring montierte Spulen b gegenüberstehen, welche einen durch die Drehbe­ wegung des Rades induzierten Strom (Generatorprinzip) einer­ seits an ein Relais 1 weiterleiten, das andererseits mit der Fahrzeugbatterie verbunden ist. Diese Verbindung wird als Sperrstrom benützt, solange ein von der Generatoreinrichtung a/b kommender Strom fließt. Im Augenblick des Stillstandes gibt das Relais 1 den von dem in der Straße verlegten Kabel über eine Antenne und eine Frequenzweiche kommenden Strom frei, der zu einem Relais 2 fließt, welches über die Zünd­ spule oder bei Dieselmotoren den Abstellmechanismus den Motor außer Betrieb setzt. On the vehicle side, a wheel drive is connected to a magnetic disk, which is divided into several sections and rotates with the wheel - drawing 3 - is connected to the coils b, which are firmly connected to the vehicle and are mounted on a similar ring forward the induced current (generator principle) on the one hand to a relay 1 , which on the other hand is connected to the vehicle battery. This connection is used as reverse current as long as a current coming from the generator device a / b flows. At the moment of standstill, the relay 1 releases the current coming from the cable laid in the street via an antenna and a crossover, which flows to a relay 2 , which turns off the engine via the ignition coil or, in the case of diesel engines, the shut-off mechanism.

Nach Freigabe des Verkehrs (Ampelstellung "grün") legt der bei der Ampel befindliche Schalter A die (Anhalte-) auf die (Anlaß-)Frequenz um, welche wie vorerwähnt schrittweise in die einzelnen Kabelsegmente geleitet wird. Über die An­ tenne und die Frequenzweiche wird der Anlasser über ein Re­ lais 3 betätigt. Das Abschalten des Anlassers geschieht über dieses Relais 3 durch den vom Generator (der "Lichtmaschine") kommenden, durch den laufenden Motor erzeugten Strom. Da der Anlasser nur bei durch das Zündschloß bewirktem Stromfluß von der Batterie her in Bewegung gesetzt werden kann, ist der Anlaßvorgang von außen her nicht zu bewerkstelligen.After the traffic has been released (traffic light position "green"), the switch A located at the traffic light switches the (stopping) frequency to the (starting) frequency, which, as mentioned, is gradually passed into the individual cable segments. The starter is actuated via a relay 3 via the antenna and the crossover. The starter is switched off via this relay 3 by the current coming from the generator (the "alternator") and generated by the running engine. Since the starter can only be set in motion from the battery when the current flows through the ignition lock, the starting process cannot be carried out from the outside.

Die Verlegung des für die Schaltvorgänge benötigten Kabels geschieht ohne großen Aufwand in einem in die Straßendecke gefrästen Schlitz. Desgleichen ist der bei der Ampel befind­ liche Schalter A beim heutigen Stand der Elektronik einfach herzustellen.The laying of the cable required for the switching operations happens without much effort in the street ceiling milled slot. The same is the one at the traffic light switch A is easy with today's electronics to manufacture.

Auf der Fahrzeugseite sind nur wenige Teile notwendig:Only a few parts are necessary on the vehicle side:

  • 1. Antenne (ein über die Fahrzeugbreite querliegender Stab genügt) mit Frequenzweiche1. Antenna (a rod across the width of the vehicle is enough) with a crossover
  • 2. der auf der Rad-Antriebsachse montierte, drehbare Magnet- und der gegenüberliegende spulenbestückte Ring und2. the rotatable one mounted on the wheel drive axle Magnetic and the opposite coil-equipped ring and
  • 3. die 3 Relais, welche mit entsprechenden Kabelverbindungen in einem Gehäuse untergebracht werden können.3. the 3 relays, which with appropriate cable connections can be accommodated in a housing.

Die Anlage kann auch vor baustellenbedingten Ampeln oder vor Schranken verwendet werden, da das Kabel zwischen zwei trapezförmigen Schienen beweglich verlegt werden kann. Diesem Verwendungszweck kommt bezüglich Luftreinerhaltung bzw. Kraftstoffersparnis erhebliche Bedeutung zu, da erfahrungs­ gemäß im Stau vor derartigen Hindernissen die Motoren fast nie abgestellt werden. The system can also be in front of traffic lights or in front of construction sites Barriers are used because the cable between two trapezoidal rails can be moved. This Purpose comes with respect to air purity or Fuel savings are of considerable importance because of experience according to the engines in traffic jam before such obstacles almost never be turned off.  

Eine andere Ausführung bewirkt dieselben Vergänge nach dem Richtfunkverfahren:
Ein mit der Ampelschaltung in Verbindung stehender Schalter löst ein Funksignal einer bestimmten Frequenz in gesteuerter Richtung aus, welches über eine Antenne mit Frequenzweiche am Fahrzeug empfangen und wie bei der beschriebenen Lösung zum Abschalten des Motors an ein Relais bei der Zündspule bezw. bei Dieselmotoren den Abstellmechanismus weiterge­ leitet wird. Damit nicht alle Fahrzeuge gleichzeitig still­ gelegt werden, wird die Schaltung des Relais gemäß der vor­ angegangenen Beschreibung an die Drehung eines Rades ge­ koppelt, so daß das Funksignal erst beim Stillstand des Fahrzeuges wirksam wird.Another version causes the same transitions according to the directional radio method:
A switch connected to the traffic light circuit triggers a radio signal of a certain frequency in a controlled direction, which is received via an antenna with a crossover on the vehicle and, as in the solution described, for switching off the engine to a relay at the ignition coil. the shutdown mechanism is passed on in diesel engines. So that not all vehicles are shut down at the same time, the circuit of the relay is coupled to the rotation of a wheel according to the description above, so that the radio signal is only effective when the vehicle is at a standstill.

Das Wiederanlassen des Motors geschieht durch Umschaltung der Funkfrequenz wie vorbeschrieben, wobei allerdings die wartende Fahrzeugkolonne nicht gruppenweise bedient werden kann.The engine is restarted by switching the radio frequency as described above, although the waiting vehicle columns are not operated in groups can.
