Description

The invention relates to a method for driving light control of a vehicle with at least two headlamps, in which a low-beam distribution, a Teilfernlichtverteilung and a high beam distribution are set as light distributions, wherein controlled to adjust one or more light distributions, a headlight range, a Ausleuchtcharakteristik and / or a horizontal tilt angle of the headlights become.

The invention further relates to a device for carrying out the method.

From the prior art devices and methods for controlling a driving light of a vehicle are generally known, in which a beam path of a generated light distribution of a headlight is adjustable. To this setting, the headlamp comprises optical elements, based on which a vertical cut-off in the light distribution of the headlight can be generated.

Furthermore, in the prior art pixel headlights with light-emitting diodes formed as light sources, which are arranged in so-called light-emitting diode arrays. The light-emitting diodes are individually controllable such that a driving light for a vehicle with different light distributions and different light-dark limits can be generated.

The DE 10 2010 006 296 A1 discloses a method for driving light control of a vehicle having at least one pivotable headlight, in which a low beam distribution, a Teilfernlichtverteilung and / or a high beam distribution are set as light distributions, wherein for adjusting one or more light distributions, a headlight range, a Ausleuchtcharakteristik and / or a horizontal tilt angle of at least a headlamp be controlled so that a rate of change in the transition of one of the light distributions is set to another variable. Furthermore, a transition from the low beam distribution to the divided high beam distribution and / or to the high beam distribution and / or a transition from the divided high beam distribution to the high beam distribution after a predetermined waiting time are started.

The invention has for its object to provide a comparison with the prior art improved method for driving light control of a vehicle and an apparatus for performing the method.

With regard to the method, the object is achieved by the specified in claim 1 and in terms of the device by the features specified in claim 9.

Advantageous embodiments of the invention are the subject of the dependent claims.

In a method for driving light control of a vehicle having at least two headlamps, a low-beam distribution, a divided high-beam distribution and a high beam distribution are set as light distributions, wherein a headlight range, an illumination characteristic and / or a horizontal tilt angle of the headlights are controlled to adjust one or more light distributions.

According to the invention, when the fog is detected in the illumination area of the headlights, the low-beam distribution or a bad weather distribution of a first headlight assigned to a roadway center and a partial distance light distribution of a second headlight assigned to the roadway edge are automatically activated, whereby the divided high-beam distribution of the second headlight is swiveled in the direction of the roadway edge.

Thus, an impairment of the driver's view of the vehicle in fog by an activated high beam is avoided in a particularly advantageous manner. Due to the activation of the partial high beam and due to the pivoting of the second headlamp in the direction of the driving band edge, the possibility of detecting the mist remains at the same time, since it is not or not adequately detected in the low beam distribution, but is easily and reliably detected in the split beam distribution due to generated reflections ,

Particularly preferably, an environment of the vehicle is detected by means of an image acquisition unit, wherein based on an evaluation of images of the image acquisition unit, the fog is detected in the surroundings of the vehicle. This detection of the mist is characterized by a low cost. Since the image data of the image acquisition unit are preferably used for adjusting the light distributions of the headlights even when there is no mist, no additional image capture unit is required to realize the fog detection.

In this case, the fog is detected, in particular, in a region of illumination of the headlights, which is illuminated with the partial high beam distribution and / or the high beam distribution, since the detection of the fog in these areas is particularly safe due to the reflections generated. In particular, confusion between fog and a wet road surface are avoided.

In addition, a fog density is preferably determined and depending on the fog density, the low-beam light distribution or the bad weather distribution is set as the light distribution of the first headlight. Under a bad weather distribution is understood to mean a light distribution, which is designed such that in poor visibility conditions, caused by fog and / or precipitation, glare of the driver of the vehicle can be avoided. For this purpose, deviating in particular from the low-beam light distribution vertical pivot angle of the headlamps and / or further lighting means of the headlights, in particular so-called fog lights, activated. Thus, a maximum view for the driver is always generated.

In order to determine the fog density, according to an advantageous development of the method according to the invention, pivoting movements of the second headlight producing the partial long-distance light distribution are carried out. In particular, very small pivoting movements are carried out, wherein due to the pivoting movements reflections or changes in the reflections of the light are caused by the fog. The reflections or changes can be detected particularly easily by means of the image acquisition unit.

In order to avoid dazzling of objects, in particular other road users and animals, the objects detected in the surroundings of the vehicle are left out of the illumination area of the headlights.

In a preferred embodiment of the method according to the invention, at least two vertical light-dark boundaries in the light distribution of the headlamp are generated by means of a mechanically actuatable optical element arranged in at least one of the headlights, in particular a mechanically actuated shutter. From the use of the mechanically actuated shutter, which is a roller or diaphragm, results in an advantageous manner that different light distributions can be generated with little effort. In particular, by means of the headlight in a light distribution, two low-beam light regions and one high-beam light beam laterally enclosed by the low beam light regions can be generated. Thus, two so-called high-beam gaps in a light distribution can be generated, which makes it possible to save at least two objects from the light distribution and to avoid their glare at the same time maximum visibility for a driver of the vehicle.

Furthermore, it is thereby possible to carry out such a control of the light distributions even in a headlight with bulbs designed as gas discharge lamps and / or halogen lamps. This control is distinguished from pixel headlights by a greatly simplified feasibility and thus very high robustness with low cost. Also, the headlamp thus controlled by conventional and inexpensive light sources, such as incandescent or gas discharge lamps, to produce a variety of light distributions.

The device according to the invention for carrying out the method comprises the image capture unit for detecting the surroundings of the vehicle, an evaluation unit for evaluating images captured by the image capture unit, and a control unit for adjusting the light distributions of the headlights as a function of the evaluation of the images. The device is characterized by a simple structure and can be realized with low material and cost.

According to one embodiment of the device according to the invention, the image acquisition unit is connected to the control unit, wherein an orientation of the image acquisition unit is adjustable in dependence on a swivel angle of the headlights and / or the swivel angle of the headlights in dependence of the orientation of the image acquisition unit is adjustable. Thus, the fog is always safely detected in the environment of the vehicle, in particular in the Teilfernlichtverteilung.

Embodiments of the invention are explained in more detail below with reference to drawings.

2 schematically the vehicle according to 1 and two objects in the direction of travel in an area in front of the vehicle,

3 schematically the vehicle according to 1 , wherein a low beam distribution and a Teilfernlichtverteilung are set and

4 schematically a partial distance light distribution of the headlights according to 1 with two vertical cut-offs and a horizontal cut-off.

Corresponding parts are provided in all figures with the same reference numerals.

In 1 is a vehicle F with an image capture unit 1 , a left first headlight 2 and a right second headlight 3 shown.

By means of the image acquisition unit 1 an environment in front of the vehicle F is detected and by means of an image acquisition unit 1 coupled evaluation unit 4 be in 2 illustrated objects O1, O2 in images B of the image acquisition unit 1 detected. The image capture unit 1 preferably includes a camera. Alternatively or additionally, the image capture unit comprises 1 a radar sensor, a lidar sensor or similar sensors, by means of which the environment can be detected in such a way that the objects O1, O2 in the captured images B can be detected. The objects O1, O2 are opposing objects O2 and / or objects O1 moving in the same direction in a region in the direction of travel in front of the vehicle F.

Depending on the detected objects O1, O2, but also depending on the traffic situation in which the vehicle F is located, by means of a with the evaluation 4 coupled control unit 5 as light distributions of the headlights 2 . 3 automatically a respective low-beam distribution AV ₂ , AV ₃ , a Teilfernlichtverteilung TFV ₂ , TFV ₃ and / or a high beam distribution FV ₂ , FV ₃ set to a driver of the vehicle F maximum illumination while maintaining legal requirements and avoiding dazzling other road users to enable. In other words, the driver of the vehicle F can drive due to the light assist function with permanently activated high beam setting, the headlight range, the Ausleuchtcharakteristik and the horizontal tilt angle are automatically adjusted such that always adapted to the current situation illumination of the front of the vehicle F area takes place and other road users are not dazzled.

By means of the headlights 2 . 3 an asymmetrical low beam distribution is generated, which is characterized in that the low beam distribution AV _{3 of} the second headlight 3 a wider headlight range than the low beam distribution AV _{2 of} the first headlight 2 so that in right-hand traffic dazzling of road users in oncoming traffic on the left side of the vehicle F is avoided. Alternatively, however, other not shown, in particular to legal requirements of different countries adapted Abblendlichtverteilungen AV ₂ , AV ₃ by means of the headlights 2 . 3 produced.

To produce the high-beam light distributions FV ₂ , FV ₃ not shown in detail headlight actuators, such as rollers, diaphragms and / or electric motors, driven in such a way that an illumination is achieved with the largest possible beam range. Alternatively or additionally, also not shown bulbs of the respective headlight 2 . 3 , which may be various and known light sources, such as incandescent lamps, light-emitting diodes and / or gas discharge lamps, within the respective headlamp 2 . 3 moved and / or switched on or off, that the high beam distributions FV ₂ , FV _{3 are} generated.

Furthermore, by means of the headlights 2 . 3 each Teilfernlichtverteilungen TFV ₂ , TFV _{3 can be} generated. The Teilfernlichtverteilungen TFV ₂ , TFV ₃ can have different light distributions, which are characterized by different tilt angle of the light cone, different illumination characteristics and / or headlights. To generate these Teilfernlichtverteilungen TFV ₂ , TFV ₃ turn the headlight actuators of the respective headlamp 2 . 3 driven. In this case, for example, the beam range of the headlights 2 . 3 by a well-known headlamp leveling, such. As electric motors can be adjusted. Alternatively or additionally, the headlight range is regulated, for example, based on the diaphragms and / or rollers.

Also for setting the different illumination characteristics, which are characterized in particular by different shapes and widths of the light cone, the bulbs are switched on or off or the headlight actuators, d. H. the apertures and / or rollers, driven.

To create the different tilt angles, the headlights 2 . 3 and / or their bulbs designed to be pivotable, with preferably headlight actuators, so-called curved light actuators, are used, which for performing a Kurvenlichtfunktion already on the headlights 2 . 3 are provided. Also the swivel angle of the headlights 2 . 3 may alternatively or additionally by targeted switching on and / or off the bulbs of the headlights 2 . 3 be set so that not the respective headlight 2 . 3 itself, but the light beam or the light distribution of the light distribution are pivoted.

The pivoting of the light cone, the change of the illumination characteristics, the light range of the light distributions and the detection of the objects O1, O2 in front of the vehicle F takes place in particular according to the in the WO 2009/112125 A1 and / or the DE 10 2010 006 296 A1 The applicant discloses methods for controlling the driving light of a vehicle, wherein the light cones are preferably pivoted to the edges of the objects O1, O2 in order to produce a glare-free space for them.

2 shows the vehicle F and two objects O1, O2 located in front of the vehicle F, the object O1 driving ahead of the vehicle F in the same direction, and the object O2 coming towards the vehicle F on an opposite carriageway. Both headlights 2 . 3 are operated in such a way that they each generate a partial high-light distribution TFV ₂ , TFV ₃ .

In the illustrated embodiment, by means of the headlights 2 . 3 caused by pivoting the Teilfernlichtverteilungen TFV ₂ , TFV _{3 of} the glare-free space for the object O1, which is in particular a vehicle F the vehicle ahead. In this case, the object O1 is enclosed between the light cones of the sub-beam light distributions TFV ₂ , TFV ₃ , so that glare of the object O1 is excluded and maximum visibility and illumination for the driver of the vehicle F is achieved.

To create this glare-free space, the headlights 2 . 3 controlled in such a way that at inner Teilfernlichtwinkeln ω1, ω2 each have a vertical bright-dark boundary HDG1, HDG2 is generated.

First, the oncoming vehicle is separated from the sub-beam distributions TFV ₂ , TFV ₃ on the left and right sides, ie, the light distributions of the left and right headlights 2 . 3 , enclosed and located in the glare-free room.

If the further object O2 appears in front of the vehicle F, wherein the object O2 is in particular a vehicle approaching the vehicle F, the light cone of the left partial beam light distribution TFV _{2 is} pivoted to the left such that a glare-free space exists for both objects O1 and O2 is produced. In a further approximation of the object O2 to the vehicle F, the light cone of the left partial high-beam light distribution TFV _{2 is} pivoted to a maximum reaching an inner maximum pivot angle ωmax. This inner maximum pivot angle ωmax is in particular by a construction of the headlights 2 . 3 and their curve light plate specified.

However, the inner maximum pivot angle .omega.max reached and the oncoming object O2 moves further to the vehicle F to, is switched from the sub-beam light distribution TFV ₂ to the low beam distribution AV _2, in order to avoid dazzling of the oncoming object O2.

In the process, the light distribution of the respective headlight facing the oncoming object O2 becomes 2 or 3 transferred from the split-beam distribution TFV ₂ , TFV ₃ in the low-beam distribution AV ₂ or AV ₃ to exclude dazzling the oncoming vehicle. In the illustrated embodiment, ie in legal traffic, this means that the light distribution of the left first headlight 2 is transferred from the divisional light distribution TFV ₂ in the low beam distribution AV ₂ when the oncoming object O2 has fallen below a limit distance.

In 3 the vehicle F is shown, wherein by means of the first headlight 2 the low beam distribution AV ₂ and the second headlight 3 the split beam light distribution TFV _{3 are} generated.

The illustrated illumination of the surroundings of the vehicle F is set when fog is detected in the surroundings of the vehicle F.

In this case, fog detected by the control unit is detected in the illumination area of the headlights 2, 3 5 automatically the low beam distribution AV ₂ of the middle of the roadway associated headlamp 2 set. Thus, for the driver of the vehicle F, avoidable glare due to the fog and an activated high beam distribution FV ₂ , FV ₃ and / or an activated partial beam light distribution TFV ₂ , TFV _{3 are} avoided.

Alternatively, instead of the low beam distribution AV ₂ in a manner not shown, a so-called bad weather distribution of the first headlight 2 activated, which allows the driver of the vehicle F with respect to the low-beam distribution AV ₂ improved visibility in fog.

To detect the fog in the vicinity of the vehicle F, the means of the image acquisition unit 1 Captured images B of the evaluation unit 4 fed and evaluated using a suitable evaluation algorithm.

It is difficult to detect fog in a camera image in the dark and to distinguish it from other environmental scenarios. Especially with activated low beam it is difficult to distinguish fog from other environmental scenarios, such as a wet road surface with certain reflective properties.

When the high beam is activated, however, the detection of the fog is much easier to carry out due to the illumination of the environment of the vehicle F. Therefore, in the illumination area of the headlights 2 . 3 detected fog by means of the control unit 5 In addition, the sub-beam distribution TFV ₃ of the second headlight assigned to the roadway edge is additionally automatic 3 activated and the sub-beam distribution TFV ₃ is pivoted in the direction of the road edge. Thus, on the one hand dazzling the driver of the vehicle F by Reflections of the sub-beam light distribution TFV ₃ avoided on the fog and on the other hand, the reliable detection of the fog from the images B of the image acquisition unit 1 allows. For this purpose, the image capture unit 1 Preferably aligned such that its optical axis is directed towards a portion of the sub-beam light distribution TFV ₃ , which has a headlight range of a high beam. This area is represented by a high beam area FB1.

Furthermore, the Teilfernlichtverteilung TFV _{3 has} an area which is characterized by a headlight range of a low beam. This area is represented by a low beam area AB1.

Between the low beam area AB1 and the high beam area FB1 is a vertical bright-dark boundary HDG 1 educated. This vertical light-dark boundary HDG is preferably by means of a mechanically actuated optical element, which in the beam path of the light source of the second headlight 3 is arranged generates. The optical element is designed as a roller or as a diaphragm. Also preferably in the first headlight 3 such an optical element is arranged. A position of the vertical cut-off line HDG 1 within the sub-beam light distribution TFV ₃ is in a simple manner by displacement or pivoting of the optical element relative to the light source of the headlight 3 possible. Thus, the size of the low beam range AB1 and the high beam range FB1 are variably adjustable.

Alternatively, in the training of the headlights 2 . 3 as a headlight with light-emitting diodes designed as light-emitting diodes, columns of LEDs and / or rows of LEDs by means of the control unit 5 controlled such that the illumination shown and / or further illumination can be generated.

The low-beam distribution AV _{2 of} the first headlight 2 and the split beam distribution TFV _{3 of} the second headlight 3 are formed such that the driver of the vehicle F no visual restriction is generated. Due to the formation of the Teilfernlichtverteilung TFV ₃ with the low beam range AB1 and the high beam area FB1 for the driver in front of the vehicle F fog-free illumination is generated and at the same time it is possible in the high beam FBI, in a simple, effective and reliable way the fog by means of the images B of the image acquisition unit 1 detected image data to detect.

Furthermore, it is possible to determine a fog density, for which purpose small pivoting movements of the secondary beam light distribution TFV ₃ generating second headlight 3 be performed. From the pivoting movements of the headlight 3 This results in reflections of the light at the fog, whereby from the reflections by means of the evaluation unit 4 the fog density is determined.

Depending on the fog density is preferably the low beam distribution AV ₂ or the bad weather distribution as light distribution of the first headlamp 2 set and / or increased at low fog density a light range of the light distribution beyond the low beam range addition.

The illustrated illumination thus allows maximum visibility for the driver of the vehicle F without glare in fog and at the same time the possibility of detecting the fog in the high beam area FB1, so that the illumination is always adaptable to the current environmental conditions. A dazzling of other road users is excluded. Furthermore, constant changes of illumination, d. H. a light image avoided, which would lead to irritation of the driver due to a "restlessness" in the generated light distribution.

In addition, due to the continuous detection of the fog in the high-beam area FB1, it is possible to switch to the "normal mode" of the light assist function with a resolution of the fog, and a maximum view for the driver by automatically switching between the low beam distributions AV ₂ , AV ₃ , the Teilfernlichtverteilungen TFV ₂ , TFV ₃ and the high beam distributions FV ₂ , FV ₃ .

The illustrated illumination is intended for a vehicle F used in legal traffic. In a vehicle F, which is intended for left-hand traffic, the split-beam distribution on the left-hand headlight and the low beam distribution on the right-hand headlight are set.

By means of the headlights 2 . 3 Furthermore, a so-called danger light can be generated. In order to reduce the increased risk potential of the objects O1, O2 resulting from a reduced visibility of the objects O1, O2 for the driver of the vehicle F and a reduced visibility, at least one of the objects O1, O2 with the vehicle F will collide Light distributions of the headlights 2 . 3 adjusted such that an optical axis of the light distribution is directed to the object O1, O2 recognized as a danger point or the objects O1, O2 recognized as danger points. The lighting of the danger objects takes place in such a way that glare of the objects is avoided.

Such a light distribution is in 4 shown. The light distribution is from the perspective of one Vehicle occupant is shown and is as Teilslichtlichtverteilung TFV _{3 of} the second headlight 3 and trained as a so-called danger spot.

To avoid dazzling one or more of the vehicle F oncoming and / or preceding objects O1, O2 is the optical element of the second headlight 3 so formed and in the beam path of the light source of the second headlamp 3 arranged that two vertical bright-dark boundaries HDG1, HDG2 in the Teilfernlichtverteilung TFV _{3 can be} generated.

A first vertical cut-off line HDG1 extends between a high-beam area FBI and a first low-beam area AB1 and a second vertical light-dark border HDG2 between the high-beam area FBI and a second low-beam area AB2.

By means of the illustrated light distribution, it is possible to generate as the driving light of the vehicle F a "partial remote light with a defined gap". In this case, a "transillumination" between several objects O1, O2 can be realized.

It is also possible that in the overtaking of other vehicles, the area in front of the vehicle F is maximally lit and at the same time a dazzling oncoming and driving ahead of road users is avoided.

Furthermore, in a manner not shown, a headlight range of the generated high beam range FB1 by means of a headlamp leveling adjustable. Thus, it is possible to "shine through" between objects O1, O2.

As already described, both headlamps are particularly preferred 2 . 3 Such optical elements, so that by means of both headlights 2 . 3 the illustrated light distribution can be generated. Thus, it is possible to produce unrepresented light distributions with up to two high beam areas and up to four low beam areas.

Due to the generation of the danger spot shown by means of the optical element at least in the second headlight 3 It is also possible that the total headlamps to capture the fog density not 3 and / or its lighting means must be pivoted, but that the determination by displacement and / or pivoting of the optical element is possible. Opposite the pivoting of the entire headlight 3 and / or its illuminant, the displacement and / or pivoting of the optical element requires little technical effort and thus a low cost.
