Abstract

Device for permitting the brake lights of a vehicle to light up early in the event of sudden braking, a first photoelectric beam which is arranged adjacent to the accelerator pedal, a second photoelectric beam which is arranged adjacent to the brake pedal and an electronic circuit which causes the brake lights to light up when the first photoelectric beam is interrupted and the second photoelectric beam is subsequently interrupted shortly afterwards being provided.

Description

Die Erfindung betrifft eine Vorrichtung zum frühzeiti­ gen Aufleuchtenlassen der Bremslichter eines Fahrzeugs bei plötzlichem Bremsen.The invention relates to a device for early brake lights on a vehicle with sudden braking.

Aus dem DE-GM 19 20 317, der DE-OS 20 11 694 und der DE 32 40 527 A1 sind Vorrichtungen bekannt, die die Brems­ lichter eines Fahrzeugs frühzeitig, also noch vor Aus­ lösen des eigentlichen Bremsvorganges, zum Aufleuchten bringen sollen.From DE-GM 19 20 317, DE-OS 20 11 694 and DE 32 40 527 A1 devices are known which brake lights of a vehicle at an early stage, i.e. before it goes out release the actual braking process, to light up should bring.

Die vorbekannten Vorrichtungen haben den Nachteil, daß sie auch dann die Bremslichter zum Aufleuchten bringen, wenn eine plötzliche Bremsung nicht beabsichtigt ist.The previously known devices have the disadvantage that they also make the brake lights come on, if sudden braking is not intended.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrich­ tung der eingangs genannten Art zu schaffen, bei der die Bremslichter frühzeitig nur dann aufleuchten, wenn eine plötzliche Bremsung beabsichtigt ist. Erfindungs­ gemäß wird diese Aufgabe durch die im kennzeichnenden Teil des Anspruchs 1 angegebenen Merkmale gelöst. Der einzige Unteranspruch gibt eine vorteilhafte Ausgestal­ tung der Erfindung an.The invention has for its object a Vorrich  to create device of the type mentioned at the outset the brake lights only light up early if sudden braking is intended. Invention according to this task is performed by the in the characteristic Part of claim 1 specified features solved. The only subclaim gives an advantageous Ausgestal tion of the invention.

Die Erfindung wird im folgenden anhand einer Zeichnung erläutert.The invention is described below with reference to a drawing explained.

Die Vorrichtung besteht aus einer ersten Lichtschranke 12 und einer zweiten Lichtschranke 16, die jeweils aus einer Lichtquelle 12′, 16′ und einem Lichtsensor 12′′, 16′′ bestehen. Dabei ist die erste Lichtschranke 12 dem Gaspedal 10 und die zweite Lichtschranke 16 benachbart dem Bremspedal 14 zugeordnet.The device consists of a first light barrier 12 and a second light barrier 16 , each consisting of a light source 12 ', 16' and a light sensor 12 '', 16 '' . The first light barrier 12 is assigned to the accelerator pedal 10 and the second light barrier 16 is adjacent to the brake pedal 14 .

Die beiden Lichtschranken werden bei Umwechseln des Fußes vom Gaspedal 10 auf das Bremspedal 14 unterbro­ chen, wobei zunächst die erste Lichtschranke 12 und sodann die zweite Lichtschranke 16 unterbrochen wird. Bei schnell erfolgenden Bremsvorgängen (sogenannten "Notbremsungen") ist die Zeitdauer zwischen der Unter­ brechung der ersten Lichtschranke 12 bis zum Unterbre­ chen der zweiten Lichtschranke 16 gering, bei "norma­ len" Bremsvorgängen ist diese Zeitdauer dagegen relativ lang. Durch Erfassen des zeitlichen Abstandes zwischen den Unterbrechungen der Lichtschranken 12, 16 durch eine elektronische Schaltung 22 kann so zuverlässig festgestellt werden, ob der Fahrer eine Notbremsung beabsichtigt. Unterschreitet der Zeitabstand zwischen der Unterbrechung der beiden Lichtschranken 12, 16 eine vorgegebene Grenze (diese wird im msec Bereich liegen), werden die Bremsleuchten 20 schon zum Aufleuchten ge­ bracht, bevor der Fuß des Fahrers die Bremspedale 14 auch nur erreicht.The two light barriers are interrupted when the foot is changed from the accelerator pedal 10 to the brake pedal 14 , the first light barrier 12 and then the second light barrier 16 being interrupted first. For fast taking place braking (so-called "emergency braking") is the time duration between the lower refraction of the first photocell 12 to interrup the second light barrier 16 chen low, at "norma len" braking operations this time period, however, is relatively long. By detecting the time interval between the interruptions in the light barriers 12, 16 by means of an electronic circuit 22 , it can thus be reliably determined whether the driver intends an emergency stop. If the time interval between the interruption of the two light barriers 12, 16 falls below a predetermined limit (this will be in the msec range), the brake lights 20 are brought to light up before the driver's foot even reaches the brake pedals 14 .
