Abstract
Description
Die Erfindung betrifft eine Steuereinrichtung für Bremsleuchten gemäß Oberbegriff des Anspruchs 1.The invention relates to a control device for brake lights according to the preamble of Claim 1.
Bei stehendem Verkehr, beispielsweise vor Verkehrsampeln, wird von Fahrern des nachfolgenden Verkehrs das längere Zeit andauernde starke Leuchten der Bremsleuchten oftmals als störend empfunden. Um die Blendwirkung der Bremsleuchten herabzusetzen, ist in der DE 31 29 814 A1 ein Verfahren beschrieben, bei dem bei Stillstand des Fahrzeugs die Bremsleuchten wenigstens teilweise erlöschen. Dies hat jedoch den Nachteil, daß bei noch fließendem nachfolgenden Verkehr eine an sich erwünschte Warnfunktion der Bremsleuchten nicht mehr gegeben ist.When the traffic is stationary, for example in front of traffic lights, drivers of the following traffic the long-lasting strong glow of the Brake lights are often perceived as annoying. The glare of the brake lights To reduce, a method is described in DE 31 29 814 A1, in which If the vehicle comes to a standstill, the brake lights go out at least partially. this has however, the disadvantage that, with subsequent traffic still flowing, one per se Desired warning function of the brake lights is no longer given.
Aus der DE 40 35 956 A1 ist eine Schalteinrichtung für heckseitige Leuchten, insbesondere für Nebelschlußleuchten, bekannt, die über einen lichtempfindlichen Sensor auf das Licht des Scheinwerfers eines nachfolgenden Fahrzeugs anspricht und die heckseitige Leuchte abschaltet. Diese Schaltungseinrichtung ist nur dann wirksam, wenn nachfolgende Fahrzeuge bei entsprechender Dunkelheit ihre Scheinwerfer eingeschaltet haben. Außerdem wird ein Abstand der nachfolgenden Fahrzeuge nicht ermittelt, so daß auch hier ein Abschalten der heckseitigen Leuchte schon dann erfolgt, wenn der nachfolgende Verkehr noch fließt.DE 40 35 956 A1 describes a switching device for rear lights, especially known for rear fog lights, which have a light-sensitive Sensor responds to the light of the headlight of a following vehicle and the rear light switches off. This circuit device is only effective if following vehicles have their headlights in the corresponding darkness turned on. In addition, there is no distance between the following vehicles determined so that the rear-side lamp is also switched off here, if the following traffic is still flowing.
Schließlich ist aus der DE 30 44 054 A1 eine Schaltungsanordnung zur Blendminderung für Zusatzbremsleuchten von Fahrzeugen bekannt, bei der ein Zeitschaltglied nach einer bestimmten Einschaltdauer eine Reduzierung oder eine vollständige Unterbrechung des Speisestroms der Zusatzbremsleuchten vornimmt. Hierbei wird nicht berücksichtigt, ob sich nachfolgende Fahrzeuge dem bereits stehenden Fahrzeug nähern oder ob bereits ein nachfolgendes Fahrzeug zum Stillstand gekommen ist. Schließlich tritt eine störende Blendwirkung nur dann auf, wenn hinter dem Fahrzeug ein weiteres Fahrzeug in dichtem Abstand steht.Finally, DE 30 44 054 A1 describes a circuit arrangement for reducing glare known for additional brake lights of vehicles, in which a timer after a a certain duty cycle a reduction or a complete interruption of the Feeds the auxiliary brake lights. This does not take into account whether vehicles behind are approaching the vehicle that is already standing or whether they are already a following vehicle has come to a standstill. Eventually an annoying occurs Glare only if there is another vehicle in the rear behind the vehicle Distance stands.
Der Erfindung liegt die Aufgabe zugrunde, eine Steuereinrichtung für Bremsleuchten oder andere rückwärtigen Leuchtsysteme eines Fahrzeugs zu schaffen, die bei stehendem Verkehr eine Reduzierung der Leuchtkraft eines am Fahrzeug angebrachten rückwärtigen Leuchtsystems ermöglicht.The invention has for its object a control device for brake lights or to create other rear lighting systems of a vehicle stationary traffic a reduction in the luminosity of an attached to the vehicle back lighting system allows.
Die Lösung dieser Aufgabe erhält man durch die im Anspruch 1 angegebenen Merkmale. Mittels einer Abstandselektronik wird in Verbindung mit Nahbereichs-Abstandssensoren, die vorzugsweise als Radarsensoren ausgebildet sind, der Abstand zum nachfolgenden Verkehr im Nachbereich gemessen. Bei Stillstand des Fahrzeugs und bei einem gleichzeitig stehenden nachfolgenden Fahrzeug wird dies von einer Steuerung als Ruhezustand erkannt, so daß für die Dauer des Ruhezustands die Bremsleuchten abgeschaltet oder wenigstens in ihrer Leuchtstärke reduziert werden. Der Fahrer des nachfolgenden Fahrzeugs wird somit nicht unnötig durch ständig mit voller Leuchtkraft leuchtenden Bremsleuchten geblendet. Sobald sich allerdings eine Abstandsdifferenz zwischen dem Fahrzeug und dem nachfolgenden Fahrzeug ergibt, kann dies die Abstandselektronik sofort feststellen, worauf die Bremsleuchten wieder auf volle Leuchtstärke geschaltet bzw. gedimmt werden können.The solution to this problem is obtained by the features specified in claim 1. Using distance electronics in conjunction with short-range distance sensors, which are preferably designed as radar sensors, the distance to the next Traffic measured in the back area. When the vehicle is at a standstill and when at the same time the following vehicle is stopped by a controller Hibernation detected, so that the brake lights for the duration of the hibernation switched off or at least reduced in their luminosity. The driver of the following vehicle is therefore not unnecessarily by constantly having full luminosity glowing brake lights dazzled. As soon as there is a difference in distance between the vehicle and the following vehicle, this can be the Determine the distance electronics immediately, whereupon the brake lights are full again Luminosity can be switched or dimmed.
Sind die Nachbereichs-Abstandssensoren Bestandteil eines an sich bekannten Parkhilfesystems, kann der schaltungstechnische Aufwand zur Realisierung der Leuchtkraftsteuerung der Bremsleuchten sehr gering gehalten werden.Are the post-range distance sensors part of a known one Parking assistance system, the circuitry required to implement the Luminosity control of the brake lights can be kept very low.
Eine vorteilhafte Weiterbildung sieht vor, daß die Abstandselektronik ein zu dicht auffahrendes Fahrzeug erkennt und daraufhin am Heck ein optisches Abstandswarnsignal aktiviert. Dies erfolgt vorzugsweise mittels einer zusätzlich am Heck des Fahrzeugs angebrachten Signalleuchte, um eine besonders deutliche Warnsignalfunktion zu erhalten.An advantageous development provides that the distance electronics are too tight recognizes the vehicle as it approaches and then an optical one at the rear Distance warning signal activated. This is preferably done by means of an additional one at the rear signal light attached to the vehicle to make it particularly clear Get warning signal function.
Die Erfindung wird nachfolgend anhand eines in einem Blockschaltbild dargestellten Ausführungsbeispiels näher erläutert.The invention is illustrated below with the aid of a block diagram Embodiment explained in more detail.
Das Blockschaltbild zeigt eine zentrale Steuerung S, an die eine Abstandselektronik 1, ein Bremspedalgeber 2, ein Bremssystem 3 und eine Intensitätssteuerung 4 angeschlossen sind. Die Intensitätssteuerung 4 ist ausgangsseitig an ein rückwärtiges Leuchtsystem eines mit unterbrochener Linie angedeuteten Fahrzeugs 5 angeschlossen, wobei es sich bei dem Leuchtsystem um die Bremsleuchten 6, 7 handelt. The block diagram shows a central control S, to which a distance electronics 1 , a brake pedal transmitter 2 , a brake system 3 and an intensity control 4 are connected. On the output side, the intensity control 4 is connected to a rear lighting system of a vehicle 5 indicated by a broken line, the lighting system being the brake lights 6 , 7 .
Die Abstandselektronik 1 ist an ihrem Eingang mit am Fahrzeug 5 angebrachten Nahbereichs-Abstandssensoren 8 verbunden, die sich am Heck des Fahrzeugs 5 befinden. Sind die Nahbereichs-Abstandssensoren 8 Teil eines Parkhilfesystems, so können vorne am Fahrzeug 5 weitere Abstandssensoren 9 für das Parkhilfesystem angebracht sein. Die Abstandssensoren 9 und die Nahbereichs-Abstandssensoren 8 sollen im dargestellten Ausführungsbeispiel Radarsensoren sein. Alternativ wäre auch die Verwendung von Bildsensoren wie z. B. einer CCD- oder CMOS-Kamera denkbar.The distance electronics 1 is connected at its input to the on-vehicle 5 short-distance sensors 8, which are located at the rear of the vehicle. 5 If the short-range distance sensors 8 are part of a parking aid system, 5 further distance sensors 9 for the parking aid system can be attached to the front of the vehicle. The distance sensors 9 and the short-range distance sensors 8 are intended to be radar sensors in the exemplary embodiment shown. Alternatively, the use of image sensors such as. B. a CCD or CMOS camera conceivable.
Im Stillstand und bei betätigter Fußbremse meldet der Bremsgeber 2 an die Steuerung S, daß die Bremse betätigt ist. Gleichzeitig erhält die Steuerung S beispielsweise über einen hier nicht dargestellten Radsensor das Signal, daß sich das Fahrzeug im Stillstand befindet. Wird der Steuerung S nun außerdem von der Abstandselektronik 1 gemeldet, daß sich im Nahbereich hinter dem Fahrzeug 5 ein weiteres stehendes Fahrzeug befindet, so veranlaßt die Steuerung S, daß die Intensitätssteuerung 4 aktiviert und diese eine Reduzierung der Leuchtstärke oder eine Abschaltung der Bremsleuchten 6, 7 vornimmt. Der Fahrer des hinter dem Fahrzeug 5 stehenden nachfolgenden Fahrzeugs wird somit in einer solchen Ruhephase (stehender Verkehr) nicht von den Bremsleuchten 6, 7 geblendet. Erst wenn sich der Abstand zwischen den beiden Fahrzeugen verändert oder ein Übergang in den fließenden Verkehr statt findet, werden die Bremsleuchten 6, 7 bei Betätigung der Bremse wieder voll ausgesteuert, d. h. die Leuchtkraft der Bremsleuchten 6, 7 wird wieder auf "Normal" geschaltet oder gestuft.At standstill and with the foot brake applied, the brake transmitter 2 reports to the control S that the brake is applied. At the same time, the control S receives the signal, for example, via a wheel sensor (not shown here) that the vehicle is at a standstill. If the control S is now also informed by the distance electronics 1 that there is another stationary vehicle in the vicinity of the vehicle 5 , the control S causes the intensity control 4 to be activated and this to reduce the brightness or switch off the brake lights 6 . 7 makes. The driver of the following vehicle standing behind the vehicle 5 is thus not dazzled by the brake lights 6 , 7 in such a resting phase (stationary traffic). Only when the distance between the two vehicles changes or a transition to flowing traffic takes place, the brake lights 6 , 7 are fully controlled again when the brake is actuated, ie the luminosity of the brake lights 6 , 7 is switched back to "normal" or graded.
Zusätzlich zu den Bremsleuchten 6, 7 kann eine weitere Signalleuchte am Heck des Fahrzeugs 5 angebracht sein, um ein Abstandswarnsignal bei einem zu dicht auffahrenden Fahrzeug abzugeben. Das Abstandswarnsignal kann aber auch durch Blinken oder durch ein noch helleres Aufleuchten der Bremsleuchten 6, 7 an den nachfolgenden Fahrer abgegeben werden. Auch kann ein Weitbereichs- Abstandsmeßsystem zur Ansteuerung verwendet werden. Entscheidend für die Frage ob Weitbereichs-Abstandsmeßsysteme oder Nahbereichs-Abstandssensoren verwendet werden, sind die Relativgeschwindigkeit und der Abstand zu dem Bezugsobjekt.In addition to the brake lights 6 , 7 , a further signal light can be attached to the rear of the vehicle 5 in order to emit a distance warning signal when the vehicle is approaching too closely. The distance warning signal can, however, also be given to the following driver by flashing or by the brake lights 6 , 7 lighting up even brighter. A wide-range distance measuring system can also be used for control. The relative speed and the distance to the reference object are decisive for the question of whether long-range distance measuring systems or short-range distance sensors are used.
Die zur Abstandsbestimmung verwendeten Nahbereichs-Abstandssensoren 8 sind für die Beeinflussung der Leuchtkraft der heckseitigen Leuchtsysteme so ausgelegt, daß sie nur den rückwärtigen Bereich der Fahrspur beobachten, auf der sich das Fahrzeug 5 befindet. Eine Beeinflussung durch versetzt oder neben dem Fahrzeug 5 rückwärtig ankommende Fahrzeuge ist dadurch ausgeschlossen. The short-range distance sensors 8 used to determine the distance are designed to influence the luminosity of the rear-side lighting systems in such a way that they only observe the rear area of the lane on which the vehicle 5 is located. This prevents any interference from vehicles arriving at the rear or next to the vehicle 5 .
