Aufgabe der Erfindung ist es, bei einem Kraftfahrzeug gemäß dem Oberbegriff des Anspruchs 1 Maßnahmen vorzusehen, mit denen Auffahrunfällen besser vermieden werden können.task The invention is in a motor vehicle according to the preamble of claim 1 measures provide, with which rear-end collisions can be better avoided.
Diese Aufgabe wird durch Kraftfahrzeug mit den Merkmalen des Anspruchs 1 gelöst. Die Erfindung ist anwendbar auf jede Art von Warnvorrichtung, welche Maßnahmen bei einem drohenden Heckaufprall vorsehen durch die der Fahrer des vorausfahrenden oder des nachfolgenden Fahrzeugs gewarnt werden oder durch die ein Eingriff in die Bremsregelung oder das Motormanagement des (vorausfahrenden) Fahrzeugs vorgenommen wird. Insbesondere können Rückleuchten des Fahrzeugs blinkend aktiviert werden, um den Fahrer des nachfolgenden Fahrzeugs vor einem zu dichten Auffahren zu warnen. Hierzu wird auf den eingangs dargestellten Stand der Technik verwiesen, welcher durch zahlreiche einschlägige Veröffentlichung ergänzt werden kann. Die Erfindung ist anwendbar auf jede Art von Rückleuchten: dauerhaft leuchtende Rückleuchten wie z.B. Nebelschlussleuchten oder die Rücklichter zum Abblendlicht, oder auf eine Fahreraktion hinweisende Leuchten (Bremsen oder Rückwärtsfahrt) oder auf blinkende Leuchten wie Warnblinken oder Notbremsblinken.These The object is achieved by motor vehicle having the features of the claim 1 solved. The invention is applicable to any type of warning device which activities Provide in case of imminent rear impact by the driver of the be warned of the vehicle ahead or of the following vehicle or by the intervention in the brake control or the engine management of the (preceding) vehicle. In particular, taillights can the vehicle will be activated flashing to alert the driver of the following Warn the vehicle of too tight a run-up. For this purpose is referred to the prior art presented at the outset, which by numerous relevant publication added can be. The invention is applicable to any type of taillights: permanently lit taillights like e.g. Rear fog lights or the taillight tail lights, or lights indicating a driver action (brakes or reverse drive) or flashing lights such as hazard lights or emergency brake lights.
Die Erfindung hat den Vorteil, dass eine für die Umfelderkennung ohnehin wünschenswerte Schmutzerfassungsvorrichtung mit genutzt wird, um die Leuchtstärke der Rückleuchten des Fahrzeugs zu beeinflussen. Hinsichtlich der Ausgestaltung einer Schmutzerfassungsvorrichtung wird auf den eingangs dargestellten Stand der Technik verwiesen. Da die Rückleuchten meist zur Warnung des nachfolgenden Verkehrs dienen wie z.B. Brems-, Warnblink- oder Nebelleuchten, wird mit der Erfindung eine Möglichkeit bereitgestellt, die Sicherheit vor Auffahrunfällen zu erhöhen, indem die Leuchtstärke der Rückleuchten erhöht werden kann, wenn eine Verschmutzung der Umfeldsensorik feststellbar ist.The Invention has the advantage that one for the environment detection anyway desirable dirt detection device is used to influence the brightness of the vehicle's taillights. With regard to the embodiment of a dirt detection device Reference is made to the prior art presented at the outset. Because the taillights mostly to warn of subsequent traffic, such as e.g. brake, Hazard or fog lights, with the invention is a possibility provided to increase the safety from rear-end collisions by the luminosity of the tail lights elevated can be detected if pollution of the environmental sensors is.
Zwar setzt die Erfindung voraus, dass von der Verschmutzung der Umfeldsensorik auf die Verschmutzung der Rücklichter geschlossen werden kann. Da dies aufgrund der benachbarten Anordnung von Rücklichtern und Umfeldsensorik in der Regel eine berechtigte Annahme ist, können mit der Erfindung die Kosten gespart werden, die mit einer eigenen, in die Rücklichter integrierten Verschmutzungserkennung verbunden sind, wie sie aus dem Stand der Technik bekannt ist.Though The invention requires that the pollution of the environment sensors on the pollution of the taillights can be closed. As this is due to the adjacent arrangement of taillights and environment sensing is usually a legitimate assumption, can with the invention saves the costs associated with its own, in the taillights Integrated pollution detection are connected as they are made known in the art.
Die Aufgabe wird auch durch ein Kraftfahrzeug mit den Merkmalen des Anspruchs 2 gelöst.The Task is also supported by a motor vehicle with the characteristics of Claim 2 solved.
Mit der Einbeziehung von Sensoren zur Erfassung von Umgebungsbedingungen kann die Leuchtstärke der Rückleuchten erhöht werden, wenn die Umgebungsbedingungen auf schlechte Sichtverhältnisse schließen lassen. Dann ist es vorteilhaft, wenn zumindest bei einer optischen Warnung des rückwärtigen Verkehrs die Leuchtstärke der Rückleuchten erhöht ist. Auch ist es möglich bei für den nachfolgenden Verkehr schwierigen Lichtbedingungen, wie z.B. bei tief voraus stehender Sonne, die Leuchtstärke der Rücklichter entsprechend anzupassen. Die Erfassung solcher Bedingungen kann z.B. mit den Sensoren für die Klimaautomatik, den Regen/Lichtsensor und/oder Kamerasystemen (z.B. zur Nachtsicht oder LKS-Systeme etc.) oder beliebigen lichtempfindlichen Bauteilen (Photodiode, Lidar-Systemen für ACC etc.). Eine Unterstützung durch einen Sonnenstandsalgorithmus in Kombination mit einer Fahrtrichtungserkennung ist auch denkbar, um eine für den nachfolgenden Verkehr blendende Wirkung einer tief stehenden Sonne festzustellen. Wenn eine blendende Wirkung erkannt würde, würde die Leuchtstärke der Rückleuchten erhöht werden.With the inclusion of sensors to detect environmental conditions, the brightness of the taillights can be increased if the ambient conditions suggest poor visibility. Then it is advantageous if at least in an optical warning of the rear traffic, the luminosity of the taillights is increased. Also it is possible with for the subsequent traffic difficult lighting conditions, such as in deep sun ahead, the luminosity of the taillights adjust accordingly. The detection of such conditions can eg with the sensors for automatic air conditioning, the rain / light sensor and / or camera systems (eg for night vision or LKS systems, etc.) or any photosensitive components (photodiode, lidar systems for ACC, etc.). A support by a sun position algorithm in combination with a direction detection is also conceivable to determine a dazzling effect of a low sun for the following traffic. If a dazzling effect were detected, the luminosity of the taillights would be increased.

Betätigte Bremslichter
können
insbesondere bei Nässe
und Dunkelheit den dicht nachfolgenden Verkehr durch die Leuchtintensität stören. Durch
Verwendung der Umfeldsensorik
Insbesondere wird bei Fahrzeugstillstand und wenn hinter dem eigenen Fahrzeug ein weiteres Fahrzeug steht (typische Situation an Ampeln) die Leuchtstärke oder Lichtleistung des Bremslichts reduziert, damit der nachfolgende Fahrzeugführer nicht unnötig geblendet wird. Die Lichtleistung wird auf ein fest vorgegebenes Maß reduziert. Die Reduzierung kann geschaltet als auch langsam über eine Rampe reduziert werden. Beim Anfahren erlischt das Bremslicht und beim nächsten Bremsen ist wieder das normale Bremslicht aktiv.Especially is at vehicle standstill and if behind your own vehicle another vehicle is (typical situation at traffic lights) the luminosity or Light output of the brake light is reduced, so that the subsequent driver not unnecessary blinded. The light output is fixed to a predetermined Measure reduced. The reduction can be switched as well as slowly over one Ramp can be reduced. When starting the brake light goes out and at the next Braking is again the normal brake light active.
Eine kontinuierliche Reduzierung der Lichtleistung kann auch proportional zur Annäherung des nachfolgenden Verkehrs erfolgen. Eine kontinuierliche oder gestufte Reduzierung der Lichtleistung kann auch im langsam fließenden Verkehr bei geringem Abstand des nachfolgenden Fahrzeugs, das mit angepasster Geschwindigkeit folgt, erfolgen.A Continuous reduction of light output can also be proportional to approach the subsequent traffic. A continuous or stepped Reduction in light output can also be slow in traffic at a small distance of the following vehicle, the adapted with Speed follows, done.
Analog dazu können auch andere Rückleuchten, insbesondere das Nebelschlusslicht oder rückwärtige Blinker in der Leuchtstärke angepasst werden.Analogous can do this other taillights, In particular, the rear fog light or rear turn signals can be adjusted in the luminosity.
Die Anpassung der Leuchtstärke in Abhängigkeit von der Distanz zum nachfolgenden Fahrzeug kann beschränkt sein auf den Einsatz bei eingeschaltetem Abblendlicht und/oder aktiven Scheibenwischern oder entsprechenden Signalen für Dunkelheit oder schlechte Sicht.The Adjusting the luminosity dependent on from the distance to the following vehicle may be limited for use with dipped beam and / or active Windscreen wipers or corresponding signals for darkness or bad View.
Insbesondere bei einer Anpassung der Leuchtstärke der Rückleuchten in Abhängigkeit vom Sonnenstand oder von der Distanz zum nachfolgenden Fahrzeug kann eine Verschmutzung der Rücklichter nicht mehr direkt durch eine in die Rücklichter integrierte Verschmutzungsmessung erfasst werden, welche allein das an den Verschmutzungsteilchen reflektierte Licht absolut auswertet, so dass in dieser Kombination die Verwendung der in die Umfeldsensorik integrierten Verschmutzungserfassungseinrichtung besonders vorteilhaft ist. Dann kann man über die Verschmutzung der Sensorabdeckung z.B. einer im Stoßfänger angeordneten 24 GHz Radar-Sensorik, auf die Verschmutzung der Rücklichter schließen. Die Verschmutzung der Radarabdeckung kann z.B. durch die Dämpfung gemessen werden.In particular, with an adjustment of the luminosity of the taillights depending on the position of the sun or the distance to the following vehicle pollution of the taillights can not be detected directly by a built-in taillights pollution measurement, which alone evaluates the light reflected on the pollution particles absolutely, so that in this combination, the use of integrated in the environment sensor pollution detection device tion is particularly advantageous. Then you can on the pollution of the sensor cover such as a bumper arranged in the 24 GHz radar sensor, close to the pollution of the taillights. The contamination of the radar cover can be measured for example by the damping.
