Description

  • The The invention relates to a motor vehicle with an Auffahrwarnvorrichtung according to the preamble of Claim 1 or 2.
  • From the generic DE 44 06 339 A1 a motor vehicle with an Auffahrwarnvorrichtung is known, which has a arranged at the rear of the vehicle environment sensor. From the backscattering of a radiated signal, at least the distance to a following vehicle is closed and, in the case of a critical approach, a warning device is activated. The warning consists in the flashing activation of brake lights or rear fog lights.
  • brake-lights serve to inform and warn the following traffic. At the same time it for The following traffic will be difficult to pollute the vehicle Tail lights to recognize.
  • From the EP 0 802 081 B1 Tail lights for motor vehicles, especially brake, flashing or tail lights are known in which by means of an integrated light-sensitive sensor contamination of the light window of the taillights is detected by the reflected on deposited dirt particles rays are detected. The luminous intensity of the taillights is regulated so that the proportion of rays reflected by the dirt particles is at least partially compensated.
  • From the DE 199 53 447 A1 is a vehicle with a radar-based rear crash warning device is known in which the intensity of the brake lights is adjusted depending on the distance to an immediately following vehicle to reduce glare.
  • From the DE 10 2004 028 860 A1 For example, an object recognition apparatus for a vehicle is known which serves to track and observe vehicles in front and is equipped with a radar for this purpose which evaluates the backscattering of the radar waves reflected by an object. The object recognition device has a dirt detection circuit, which from the transit times and intensities of the reflected radar waves on a pollution of the radar antenna or its cover closes. If soiled, parameters can be adapted or a warning can be issued.
  • 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.
  • 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.
  • 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.
  • 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.
  • The Task is also supported by a motor vehicle with the characteristics of Claim 2 solved.
  • 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.
  • Based the single figure becomes an embodiment shown.
  • The figure shows two consecutive vehicles 1 and 2 , wherein the arrow indicates the direction of travel. The vehicle ahead 1 , has a transmitter close to each other on its rear side 3 and receiver 4 , which represent the environmental sensors. With regard to the technical details of signal processing, we refer to the aforementioned DE 44 06 339 A1 , In the assessment of whether a critical situation exists, is also the means of a speed sensor 6 measured vehicle speed. When the critical conditions are reached, eg when a critical distance is reached, the control unit activates 5 the brake lights 7 , Other taillights on the rear of the vehicle may also be activated to warn the following traffic of too tight a run-up. Regarding the from the control unit 5 Activated measures are known from the prior art many possibilities.
  • Furthermore, a dirt detection device 8th provided, which is known from the prior art for distance warning devices and will not be explained further. Reference is made to the relevant prior art described in the introduction. Such a dirt detection device 8th is part of the environmental sensor system 3 . 4 and integrated into it, because thresholds and parameters have to be adjusted in case of contamination, radiation power has to be increased or warned.
  • The dirt detection device 8th now controls the luminous intensity control unit 9 which, in turn, the taillights 7 controls. The control takes place in such a way that, according to the degree of soiling, the luminous intensity is increased with increasing contamination.
  • In addition, the dirt detection device 8th also the control unit 5 to initiate a warning output to the driver of the own (preceding) vehicle or to influence the thresholds for the warning to a rearward driver. Provided a cleaning system for the taillights 7 is provided in a vehicle, this can also be activated when a contamination is detected.
  • in the Below, further advantageous embodiments are shown.
  • Operated brake lights can interfere with the traffic intensity due to the light intensity, especially in wet and dark conditions. By using the environment sensor 3 . 4 the distance to the following vehicle can be measured as a function of the distance the luminosity of the taillights 7 be set.
  • 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.
  • 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.
  • Analogous can do this other taillights, In particular, the rear fog light or rear turn signals can be adjusted in the luminosity.
  • 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.
  • 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.
