Description

Die Erfindung betrifft Fahrtrichtungsanzeiger mit automatischer Abschaltung der Blinkleuchten für Kraftfahrzeuge, insbesondere Krafträder.The The invention relates to turn signals with automatic shutdown the flashing lights for motor vehicles, especially motorcycles.

Bei motorisierten Zweirädern des gehobenen Preissegments sind z.T. automatisch abschaltende Blinksysteme erhältlich, welche jedoch nicht mit vertretbarem Aufwand nachrüstbar sind. Es sind Lösungen mit und ohne integriertem Blinkgeber bekannt, die mit

  • – Ultraschall zur Erfassung der Schräglage ( DE 295 00 300 ),
  • – Zeitgeber ( DE 090 15 577 ),
  • – Libellen und Lichtschranken zur Erfassung der Schräglage ( DE 199 51 195 ),
  • – Drehwinkelgeber am Lenker ( DE 100 08 131 ),
  • – Erfassung der Gasgriffstellung ( DE 299 15 723 ),
  • – Gyrosensor zur Erfassung der Schräglage ( DE 198 44 588 ),
  • – Querbeschleunigungssensor zur Erfassung der Schräglagenänderung ( DE 101 00 218 ) oder
  • – fest eingestellter Weg-Zeit Bedingung ( DE 282 72 12 )
eine automatische Abschaltung bewirken. Diese Systeme haben entweder nicht hinreichend zuverlässige Abschaltmechanismen, benötigen recht teure Bauelemente, und / oder sind nur schwer nachrüstbar. Im Handel sind noch keine automatisch abschaltenden Blinkeinrichtungen erhältlich. Die Notwendigkeit eines solchen Systems resultiert einerseits aus sicherheitstechnischen, andererseits aus komfortorientierten Aspekten. Dass im eingeschalteten Zustand vergessene Fahrtrichtungsanzeiger zu Mißverständnissen und gefährlichen Situationen führen können, ist allgemein bekannt. Ein Komfortgewinn ist offensichtlich, da sich der Fahrer nach dem Abbiegen, Überholen und Spur wechseln auf wichtigere Sachen konzentrieren kann.In motorized two-wheelers of the upper price segment partly automatic turn-off flashing systems are available, which, however, can not be retrofitted with reasonable effort. There are solutions with and without integrated flasher known with the
  • - Ultrasound for detecting the tilt ( DE 295 00 300 )
  • - Timers ( DE 090 15 577 )
  • - Dragonflies and photoelectric sensors for detecting the inclination ( DE 199 51 195 )
  • - rotary encoder on the handlebar ( DE 100 08 131 )
  • - Detecting the throttle grip position ( DE 299 15 723 )
  • - Gyrosensor for detecting the tilt ( DE 198 44 588 )
  • - lateral acceleration sensor for detecting the inclination change ( DE 101 00 218 ) or
  • - fixed path-time condition ( DE 282 72 12 )
cause an automatic shutdown. These systems either do not have sufficiently reliable shutdown mechanisms, require quite expensive components, and / or are difficult to retrofit. There are no automatic turn-off devices available in the market. The necessity of such a system results, on the one hand, from safety-related aspects and, on the other hand, from comfort-oriented aspects. It is common knowledge that forgotten direction indicators when switched on can lead to misunderstandings and dangerous situations. A gain in comfort is evident as the rider can focus on more important things after turning off, overtaking and changing lanes.

Aufgabe der in Schutzanspruch 1 angegebenen Erfindung ist die Schaffung einer ausreichend zuverlässig automatisch abschaltenden, kostengünstigen und einfach nachrüstbaren Blinkanlage mit integrierter Warnblinkfunktion.task the protection specified in claim 1 invention is the creation one sufficiently reliable automatically turn off, cost-effective and easy to retrofit Flashing system with integrated hazard warning function.

Durch die Verwendung eines Mikrocontrollers (1) in Verbindung mit einem geeigneten Algorithmus sind einerseits keine weiteren Bauteile zur Erzeugung der Blinkimpulse notwendig, andererseits ist als Signalgeber für die automatische Abschaltung ein in Radnähe befestigter Reed-Kontakt (4) in Verbindung mit einem Magneten am Rad ausreichend. Ein solcher Sensor, der z.B. auch bei Fahrrad-Tachometern Anwendung findet, ist sehr kostengünstig, ebenso wie ein für diese Anwendung geeigneter 8-Bit-Conroller. Der nachträgliche Einbau ist einfach, da nach Austauschen des originalen Blinkgebers durch die in Schutzanspruch 1 angegebenen automatische Blinkeinrichtung nur der Reed-Kontakt (4) mit Magnet und, je nach Typ, 3 bzw. 4 Taster (2a – 2d) zur Bedienung installiert werden müssen – letztere nur, falls serienmäßig Schalter eingebaut sind. In der Serienherstellung würde der kompliziert aufgebaute Blinkgeber herkömmlicher Bauart entfallen, ebenso wie ein teurer Blinkschalter mit mechanischer Rückstellung. Eine zusätzliche Warnblinkanlage, wie sie z.B. im Zubehörhandel erhältlich ist, kann auch entfallen, bzw. muß nicht nachträglich eingebaut werden.By using a microcontroller ( 1 ) in conjunction with a suitable algorithm on the one hand, no further components for generating the flashing pulses necessary, on the other hand, as a signal generator for automatic shutdown, a near the wheel mounted reed contact ( 4 ) in conjunction with a magnet on the wheel sufficient. Such a sensor, which is also used, for example, in bicycle tachometers, is very cost-effective, as is an 8-bit controller suitable for this application. The subsequent installation is simple because after replacing the original flasher by the protection indicated in claim 1 automatic flashing device only the reed contact ( 4 ) with magnet and, depending on the type, 3 or 4 buttons ( 2a - 2d ) must be installed for operation - the latter only if standard switches are installed. In series production would be omitted the complicated constructed flasher of conventional design, as well as an expensive flasher switch with mechanical reset. An additional hazard warning lights, such as those available in the accessory trade, can also be omitted, or must not be retrofitted.

Die automatische Abschaltung der Blinkleuchten (3), welche die Möglichkeit der manuellen Abschaltung mittels Taster (2d) ergänzt, funktioniert ausreichend zuverlässig durch folgenden Programmablauf:

  • – Erfassung des Geschwindigkeitsverlaufs nach Einschalten der Blinkleuchten (3) mit den Signalen des Sensors (4) unter Berücksichtigung von Mindestgeschwindigkeit und ab dem Einschaltzeitpunkt zurückgelegtem Mindestweg,
  • – Abschaltung entweder nach einer definierten Blinkdauer, falls während dieser Zeit kein Geschwindigkeitsabfall um einen bestimmten Wert gemessen wurde (Spurwechsel, Überholen) oder
  • – falls der erwähnte Geschwindigkeitsabfall während dieser Blinkdauer eintritt (bevorstehender Abbiegevorgang): Abschaltung nach anschließendem definiertem Geschwindigkeitsanstieg (Kurvenende).
The automatic switch-off of the turn signals ( 3 ), which offers the possibility of manual shutdown by means of a button ( 2d ), works reliably enough through the following program sequence:
  • - Recording the speed profile after switching on the turn signals ( 3 ) with the signals of the sensor ( 4 ) taking into account the minimum speed and the minimum distance traveled from the time of switch-on,
  • - Shutdown either after a defined flash duration, if during this time no drop in speed has been measured by a certain value (lane change, overtaking) or
  • - if the mentioned drop in speed occurs during this blinking time (impending turn): switch-off after subsequent defined increase in speed (end of curve).

Bei dem in 1 dargestellten Ausführungsbeispiel werden die Blinkleuchten (3) mittels Transistorstufen (5) in Verbindung mit Relais (6) angesteuert, möglich ist auch eine Ansteuerung durch Leistungstransistoren. Je nach Ausführung und Einbauort im Fahrzeug kann ein integrierter Tongenerator sinnvoll sein, um bei eingeschalteten Blinkleuchten den Benutzer akustisch darauf aufmerksam zu machen.At the in 1 illustrated embodiment, the turn signals ( 3 ) by means of transistor stages ( 5 ) in conjunction with relays ( 6 ), it is also possible to drive by power transistors. Depending on the design and installation location in the vehicle, an integrated tone generator may be useful to alert the user acoustically when the flashing lights are switched on.
