Abstract

Operating a brake pedal switches a brake light off if a vehicle's speed is below a preset threshold. After being switched off the brake light is switched on after the brake pedal is released and operated again below a preset speed threshold for a defined period.

Description

Die Erfindung bezieht sich auf ein Verfahren und eine Vorrichtung zur Steue­ rung eines Bremslichtes nach dem Oberbegriff des Patentanspruchs 1 und 4.The invention relates to a method and a device for control tion of a brake light according to the preamble of claim 1 and 4th

Die an Fahrzeugen üblicherweise vorgesehenen Bremslichter sollen beim Aufleuchten dem nachfolgenden Verkehr bzw. die Fahrer nachfolgender Fahrzeuge eine Fahrzeugverzögerung und damit eine Änderung des Ver­ kehrsflusses signalisieren. Die bekannten Bremslichtsteuerungen sollen da­ mit eine Warn- bzw. Signalmeldung erzeugen, der eine Änderung des Ver­ kehrsflusses unmittelbar folgt. Um diese Signalwirkung zu erhöhen, wird seit einigen Jahren zusätzlich zu den zwei seitlichen Bremslichtern am Heck die sog. dritte Bremsleuchte an der Heckscheibe angebracht.The brake lights usually provided on vehicles are said to Illuminate the following traffic or the drivers behind Vehicles a vehicle deceleration and thus a change in Ver signal flow. The well-known brake light controls are said to be there generate a warning or signal with a change in Ver flow follows immediately. In order to increase this signal effect, a few years in addition to the two side brake lights at the rear So-called third brake light attached to the rear window.

Nach dem Stillstand des Fahrzeuges ist demnach kein Signal mehr erforder­ lich, das eine Verzögerung anzeigt, insbesondere dann nicht, wenn der nachfolgende Verkehr auch bereits zum Stillstand gekommen ist. Bei kriti­ schen Situationen durch den Stillstand des Fahrzeuges kann der heranna­ hende Verkehr insbesondere durch die Warnblinkanlage gewarnt werden.After the vehicle has come to a standstill, a signal is no longer required Lich, which indicates a delay, especially not when the subsequent traffic has already come to a standstill. At kriti situations due to the vehicle being at a standstill traffic in particular be warned by the hazard warning lights.

Viele Fahrzeugführer betätigen jedoch auch nach dem Fahrzeugstillstand aus verschiedenen Gründen das Bremspedal, wodurch das Bremslicht un­ nötig weiter leuchtet; so z. B. im Stadtverkehr an Ampeln, Kreuzungen und Vorfahrtstraßen, bei Stau mit mehrmaligem Anfahren, Abbremsen und Hal­ ten oder bei Fahrzeugen mit Automatikgetriebe. Meist wird das Bremspedal aus Bequemlichkeit weiter betätigt, um die Handbremse nicht benutzen zu müssen. In diesen Situationen wird nicht unerheblich elektrische Energie und damit indirekt Kraftstoff in einem Kraftfahrzeug verbraucht.However, many drivers also operate after the vehicle has come to a standstill for various reasons the brake pedal, causing the brake light un  necessary continues to light; so z. B. in city traffic at traffic lights, intersections and Priority roads, in traffic jams with multiple starts, braking and hal ten or in vehicles with automatic transmission. Mostly the brake pedal operated for convenience so as not to use the handbrake have to. In these situations, electrical energy and electricity is not insignificant thus indirectly consumes fuel in a motor vehicle.

Es ist daher Aufgabe der Erfindung, ein Verfahren bzw. eine Vorrichtung eingangs genannter Art derart zu verbessern, daß unnötiger Energiever­ brauch verhindert wird.It is therefore an object of the invention to provide a method and a device to improve such type that unnecessary energy ver need is prevented.

Diese Aufgabe wird durch die Merkmale des Patentanspruchs 1 bzw. 4 ver­ fahrensmäßig bzw. vorrichtungsmäßig gelöst.This object is verified by the features of claims 1 and 4, respectively solved in terms of driving or device.

Vorteilhafte Weiterbildungen der Erfindung sind die Gegenstände der ab­ hängigen Patentansprüche.Advantageous developments of the invention are the subjects of the pending claims.

Erfindungsgemäß wird bei einem Verfahren zur Steuerung eines Bremslich­ tes in Kraftfahrzeugen auf die Betätigung eines Bremspedals hin das Brems­ licht auch bei betätigtem Bremspedal ausgeschaltet, wenn die Fahrzeugge­ schwindigkeit unterhalb einer vorgegebenen Geschwindigkeits-Schwelle liegt. Dabei kann die vorgegebene Geschwindigkeitsschwelle bei 0 km/h lie­ gen; d. h. das Bremslicht wird nur bei vollkommenem Fahrzeugstillstand ausgeschaltet. Die vorgegebene Geschwindigkeitsschwelle kann jedoch auch geringfügig über 0 km/h (z. B. bei 5 km/h) liegen, um ein unstetes Auf­ leuchten des Bremslichtes zwischen völligem Fahrzeugstillstand und Rollen bei sehr geringer Fahrzeuggeschwindigkeit zu verhindern. Dabei können entweder alle Bremslichter oder aber nur ausgewählte Bremslichter, z. B. die sog. dritte Bremsleuchte, eines Fahrzeuges ausgeschaltet werden. Das Fahrzeuggeschwindigkeitssignal liegt bei heutigen Fahrzeugen in vielen Steuergeräten als elektrisches Signal bereits vor. Die Erfindung kann bei­ spielsweise in ein ohnehin bereits vorhandenes sog. Lichtmodul, das bisher die Funktionen anderer Fahrzeuglichter und Fahrzeugbeleuchtungen steuert, integriert werden.According to the invention, in a method for controlling a brake tes the brake in motor vehicles upon actuation of a brake pedal Light also switched off when the brake pedal is pressed when the vehicle speed below a predetermined speed threshold lies. The specified speed threshold can be 0 km / h gene; d. H. the brake light is only on when the vehicle is completely stationary switched off. The predefined speed threshold can, however are also slightly above 0 km / h (e.g. at 5 km / h) to make the the brake light illuminates between complete vehicle standstill and rollers to prevent at very low vehicle speed. You can either all brake lights or only selected brake lights, e.g. B. the so-called third brake light of a vehicle can be switched off. The  Vehicle speed signal is present in many vehicles today Control units as an electrical signal. The invention can for example in a so-called light module, which already exists anyway controls the functions of other vehicle lights and vehicle lights, to get integrated.

Vorzugsweise wird das Bremslicht nach Unterschreiten der vorgegebenen Geschwindigkeits-Schwelle zeitverzögert (z. B. nach 2 sek) ausgeschaltet, um die Fahrer der nachfolgenden Fahrzeuge lange genug zu warnen.The brake light is preferably switched on after falling below the predetermined value Speed threshold switched off with a time delay (e.g. after 2 seconds), to warn the drivers of the following vehicles long enough.

In einer weiteren vorteilhaften Ausgestaltung der Erfindung wird das ausge­ schaltete Bremslicht nach einem Loslassen und einer erneuten Betätigung des Bremspedals unterhalb der vorgegebenen Geschwindigkeits-Schwelle für eine definierte Zeitdauer eingeschaltet und anschließend auch bei weiter betätigtem Bremspedal wieder ausgeschaltet. Hierdurch kann beispielsweise entweder eine Funktionsüberprüfung vorgenommen werden oder ein im Stau herannahendes Fahrzeug willkürlich zusätzlich gewarnt werden.In a further advantageous embodiment of the invention, this is done switched on the brake light after releasing it and pressing it again the brake pedal below the specified speed threshold switched on for a defined period of time and then also with continue the brake pedal is switched off again. This can, for example either a functional check will be made or a traffic jam approaching vehicle can be additionally warned arbitrarily.
