    Control device for a lighting device of a motor vehicle and method for controlling such a lighting device
    The invention relates to a control device for controlling at least one lighting device for a motor vehicle or for controlling a motor vehicle headlight, which has at least one lighting device which at least one lighting device at least for generating at least one defined dimmed light distribution, in particular of at least one defined low beam light distribution an area in front of the lighting device, in particular in an area in front of the motor vehicle, is set up.
    Furthermore, the invention relates to a lighting device for a motor vehicle, which is at least one lighting device at least for generating at least one defined dimmed light distribution, in particular of at least one defined low-beam distribution, in an area in front of the lighting device, in particular in an area in front of the motor vehicle is set up.
    Moreover, the invention relates to a motor vehicle headlight, which comprises at least one such lighting device.
    In addition, the invention relates to a lighting device system for a motor vehicle, wherein the lighting device system comprises two motor vehicle headlights, a left and a right motor vehicle headlight, and wherein the
    Lighting device system is intended for a motor vehicle for right-hand traffic / left-hand traffic.
    In addition, the invention also relates to a motor vehicle with at least one, in particular two such motor vehicle headlights or with an illumination device system described above.
    Finally, the invention also relates to a method for driving at least one lighting device described above or one mentioned above
    Lighting device systems.
    In motor vehicle headlights, for example in car headlights, intelligent systems are currently in use that specifically modify the light distributions in low beam and high beam operation in order to achieve optimum visibility in the dark, without dazzling other road users.
    The following systems are currently used in particular: 1) In dipped-beam mode or dimmed-out mode, one of the following light distributions can be activated or switched between, depending on the situation: • Country road • Motorway • City light • Bad weather
    Depending on various factors (vehicle speed, steering angle, road surface moisture or windscreen wiper operation, detected street lighting, GPS input, ...), one of these 4 light functions, each generating a different dimmed light distribution, is activated. For example, city lights can be activated if the vehicle speed is 60 km / h or street lighting (automatically detected by the vehicle).
    These light functions are known as AFS (Adaptive Front Lighting System). With these dimmed light functions, no camera information is taken into account. 2) Main beam: If all the conditions prescribed by law for main beam are met (no local area, sufficient ambient brightness, no oncoming or approaching vehicles), the main beam can be activated. In addition to a manual activation by the driver, there is also the option of high beam light automatically under
    Use of an optical imaging system, e.g. via a camera or camera system.
    An extension of the classic high beam is the so-called ADB (Adaptive Driving Beam) system. In this case, vehicles traveling ahead and oncoming vehicles are recognized via an optical image capture system. Specific
    Lighting device for motor vehicles, in particular motor vehicle headlights, are able to produce a high beam distribution, in which the area of the preceding and oncoming vehicles is deliberately hidden. Thus, under the conditions • no area of the area and • sufficient ambient brightness in front of the motor vehicle main beam can be provided without dazzling other drivers by illuminating only those areas in which there are no other vehicles. As a result, road safety can be significantly increased on open roads. For certain dimmed light distributions, in particular for the highway and motorway light distribution, an asymmetric light distribution is prescribed in the law, which should selectively illuminate the right edge of the road in right-hand traffic. For left-hand traffic is provided accordingly, that the left lane edge should be further illuminated.
    Such dimmed light distributions, which further illuminate the respective own roadway edge, are referred to as low-beam light distributions and the corresponding light function is referred to as low-beam function.
    In such Abblendlichtverteilungen, however, the problem of mirror glare of a vehicle ahead can occur. Due to the asymmetrical design of the low-beam light distribution, the driver of a vehicle in front can glare over the outside mirror, namely (primarily) in the case of right-hand traffic via the right-hand side mirror and left-hand traffic via the left-hand side mirror.
    In the asymmetry region of the low-beam distribution, its bright-dark boundary, as known, increases at a certain angle, e.g. at 45 ° to the horizontal (viewed in a known manner on a vertical screen at a defined distance, e.g., 25 meters, from the lighting device).
    In particular, the described problem also occurs in lighting devices which have a light distribution, in particular a low beam distribution, of individual light segments, e.g. next to each other or side by side and superimposed light segments, build. The light segments are, for example, vertically standing, in particular approximately rectangular, or square.
    In such lighting devices, it is often provided that the asymmetry in the low beam distribution, i. the asymmetry section of the cut-off line rises below 90 °.
    In such lighting devices, the described problem is particularly noticeable, and in certain driving situations, the situation may arise that the glare in the (high beam) ADB operation by considering the camera data even lower than in the current driving situation by law prescribed low beam distribution ( eg high street light).
    It is an object of the present invention to provide a solution to the above problem.
    This object is achieved with a control device mentioned in the introduction in that, according to the invention, the at least one lighting device is set up to provide at least one defined dimmed light distribution, in particular at least one defined one
    Dipped-beam distribution • with dimmed light distribution or dipped-beam distribution switched on, modify them at least with regard to their position and / or shape, and / or • switch on the dimmed light distribution or dipped beam distribution, modified with regard to their position and / or their shape , and wherein the control device on the basis of information, which from at least one object recognition system, eg an optical image acquisition system, wherein the at least one object recognition system monitors the surroundings in front of the illumination device or motor vehicle, in particular at least the area illuminated by the at least one dimmed light distribution, in particular the at least one low beam distribution, which controls at least one illumination device in such a way, in the case of a lighting device or a motor vehicle for right-hand / left-hand traffic, the right / left outside mirror of a preceding motor vehicle is not illuminated when the dimmed light distribution is activated, in particular when the dipped beam distribution is activated, and / or when the dimmed light distribution, in particular the dipped beam distribution, is switched on.
    Furthermore, this object is achieved with an illumination device mentioned in the introduction, wherein according to the invention the illumination device is associated with a control device according to the invention or the illumination device comprises such a control device according to the invention, and wherein the at least one illumination device is adapted to at least one defined dimmed light distribution, in particular at least one defined
    Dipped beam distribution • when the dimmed light distribution or dipped beam distribution is switched on, modify it at least with regard to its position and / or shape, and / or • the dimmed light distribution or dipped beam distribution, with regard to its
    Modified and switched to its shape, and wherein the lighting device comprises at least one object recognition system or the lighting device is associated with at least one object recognition system, and wherein the control device is adapted, based on information derived from the at least one object recognition system the at least one object recognition system monitors the surroundings lying in front of the lighting device or the motor vehicle, in particular at least the area illuminated by the at least one dimmed light distribution, in particular the at least one low-beam light distribution, to control the at least one lighting device in such a way that in the case of a lighting device or a lighting device Motor vehicle for right-hand traffic / left-hand traffic The right / left exterior mirror of a motor vehicle driving in front when the dimmed light distribution is activated, in particular when the dipped beam distribution is activated , and / or when switching on the dimmed light distribution, in particular the low-beam light distribution, is not illuminated.
    In addition, this object is achieved with a lighting device system described above, wherein the lighting device system comprises at least one lighting device according to the invention, which is at least one lighting device, a left / right vehicle headlight or part of a left / right motor vehicle headlight, and wherein the two motor vehicle headlights are adapted to, in common at least one dimmed light distribution, in particular to produce at least one low beam distribution, and wherein the lighting device system comprises at least one control device according to the invention or at least one control device according to the invention is associated with the lighting device system, and wherein the lighting device system comprises at least one object recognition system or at least one object recognition system is associated with the lighting device system, and wherein the control device is set up on the basis of information which originate from the at least one object recognition system, the at least one object recognition system illuminating the surroundings in front of the lighting device or the motor vehicle, in particular at least those illuminated by the at least one dimmed light distribution, in particular the at least one low beam light distribution Area monitored to control the at least one lighting device such that in a lighting device system for right-hand traffic / left traffic, the right / left
    Outside mirror of a motor vehicle driving ahead with activated dimmed light distribution, especially when activated low beam distribution, and / or when switching on the dimmed light distribution, in particular the low beam light distribution is not illuminated.
    Finally, the invention is achieved by a method mentioned at the outset, which is characterized by the following steps: monitoring an environment ahead of the illumination device or the motor vehicle, in particular at least the one of the at least one dimmed light distribution, in particular the at least one
    Abblendlichtverteilung, illuminated area with at least one object recognition system, • controlling the at least one lighting device or the
    Lighting device system by at least one control device on the basis of information, which of the at least one
    Objekterkennungssystem such that a defined dimmed light distribution, in particular at least one defined Abblendlichtverteilung • is modified at dimmed light distribution or low beam distribution at least with regard to their location and / or on their shape, and / or • the dimmed light distribution or low beam distribution, modified in view of their position and / or on their shape, is turned on, so that in a lighting device or a motor vehicle for right-hand / left-hand traffic of the right / left exterior mirrors of a preceding motor vehicle with activated dimmed light distribution, especially when activated low-beam distribution, and / or is not illuminated when switching on the dimmed light distribution, in particular the low beam distribution.
    With an object recognition system, e.g. an optical image acquisition system, in particular a camera or a camera system, according to the invention the area or the environment is observed in front of a motor vehicle.
    Such an object recognition system is set up to recognize at least one vehicle ahead of the vehicle, in particular a passenger car, in which the object recognition system is mounted. Preferably, the position and / or distance of the preceding vehicle with respect to the object recognition system can be determined. On the basis of this information, a control according to the invention can already take place.
    Preferably, such an object recognition system is set up to also determine details or certain structures of the preceding vehicle, in particular one or the two exterior mirrors or preferably also their position with respect to the object recognition system.
    As a rule, in such an object recognition system as described above, e.g. to trade one or more cameras. However, the object recognition system may also include one or more corresponding sensors, e.g. Distance sensors, with which the necessary information can be determined.
    However, the object recognition system may also consist of car-to-car communication via which vehicles communicate their position, or the object recognition system may also make available in a communication device with a central entity which has information about vehicle positions and these other vehicles , consist.
    According to the invention, the information determined using the object recognition system is now also used in the dimmed light mode, namely in such a way that a preceding motor vehicle would be illuminated in such a way by switching on a dimmed light distribution, in particular a dipped beam distribution or by an already activated dimmed light distribution, in particular dipped beam distribution in that its driver would be blinded or blinded by an exterior mirror, the dimmed light distribution, in particular the low beam distribution, is switched on in a modified manner, or the activated dimmed light distribution, in particular dipped beam distribution, is modified such that such a glare can be avoided.
    Within the scope of the legal requirements, a dimmed light distribution, in particular a low-beam light distribution, is modified in accordance with the invention in such a way that the driver driving in front is not dazzled by the exterior mirrors of his vehicle.
    The defined dimmed light distribution or low-beam distribution corresponds to a conventional (dimming) light distribution known from the prior art and typically used in known vehicles.
    The inventively modified dimmed light distributions or modified low-beam light distributions differ from the defined light distribution, which can also be referred to as dimmed basic light distribution and basic low-beam light distribution.
    If the majority speaks here of the modified dimmed light distributions or of the modified dipped beam distributions, it should be noted that according to the invention, in principle, only one modified light distribution corresponding to a defined light distribution can be provided. This is then so strongly modified in relation to the defined light distribution that for a large number of possible traffic situations dazzling of the preceding vehicle or of the driver or of the occupants can be avoided or at least reduced.
    However, it is preferably provided that, depending on the situation which is determined with the at least one optical image acquisition system, the defined light distribution is modified to the extent that no glare occurs or the glare is sufficiently reduced. This results in a large number of different modified light distributions, depending on the situation in front of the motor vehicle.
    According to the invention, it is thus proposed to use a special dipped-beam mode or dimmed light mode which, while complying with the corresponding legal requirements, provides information. Camera taken into account in order to realize a non-dazzling dimmed light distribution, in particular a low beam distribution, such as a city light distribution in the area of a preceding vehicle. For this purpose, the asymmetry region of the light distribution required for the illumination of the roadway edge is preferably shifted so far to the right / left that this asymmetry region no longer hits the right / left mirror of the preceding vehicle in right / left traffic.
    So far, a distinction is made in main light functions between low beam (including AFS functions as described above) and high beam with ADB. In low-beam operation, a suitable light distribution has hitherto been selected via parameters such as vehicle speed, steering angle, ambient brightness, etc. The information e.g. So far, a camera has not been taken into account, only in ADB high beam operation was the hiding of a vehicle via camera information.
    According to the invention, information from at least one object recognition system is now also used in low-beam operation in order to reduce or completely prevent glare from preceding vehicles via their exterior mirrors.
    It may be provided that the control device controls the lighting device in such a way that, when the dipped beam distribution is activated, the entire dimmed light distribution, in particular the entire dipped beam distribution, or at least a part of this light distribution is displaced horizontally and / or vertically such that is not illuminated by the thus modified dimmed light distribution, in particular low beam distribution in a lighting device or a motor vehicle for right-hand / left-hand traffic, the right / left exterior mirror of a preceding motor vehicle with activated light distribution and / or on switching on the lighting device such that the dimmed light distribution, in particular, the low-beam distribution, or at least a part thereof is displaced such that in a lighting device or a motor vehicle for computing traffic / left-hand traffic, the right / left exterior mirrors of a preceding motor vehicle is not illuminated when the light distribution is activated.
    Alternatively or additionally, it may be provided that the control device in the case of a lighting device which has a light distribution, preferably a dimmed light distribution, in particular a low-beam light distribution, consists of individual light segments, e.g. horizontal side by side or side by side and vertically superimposed light segments, the control device controls the lighting device such that when activated dimmed light distribution, especially when activated low beam distribution, those light segments which would illuminate a right / left side mirror of a preceding motor vehicle with activated light distribution, dimmed or be turned off and / or turn on a dimmed light distribution, in particular a low beam distribution, these light segments are dimmed or not turned on, so by the modified dimmed light distribution, in particular modified Abblendlichtverteilung, in a lighting device or a motor vehicle for right / left traffic of the right / left outside mirror of a vehicle in front is not illuminated when light distribution is activated.
    It can be advantageous if the control device is set up to control the at least one lighting device permanently, at least from the time at which the dimmed light distribution, in particular low-beam distribution, is switched on, such that the left / right traffic lights / motor vehicle is the right / left Exterior mirrors of a preceding vehicle
    Motor vehicle is not lit.
    It is preferably provided that the at least one object recognition system observes the surroundings during the entire switch-on time of the dimmed light distribution / low-beam distribution so that the light distribution can be optimally adapted to the changing circumstances.
    It is particularly advantageous if the at least one object recognition system is already active before switching on the affected light distribution so that it can already be switched on as a modified light distribution according to the present invention and taking into account the preceding traffic if the dimmed light distribution / dimming light distribution is switched on.
    In particular, it can be advantageous if the control device is set up to control the at least one illumination device in such a way that, taking into account the information originating from the at least one object recognition system, the maximum possible range of the defined light distribution, in particular the defined low-beam distribution, in particular the entire range of defined light distribution, in particular the defined low-beam distribution, is illuminated.
    In particular, it can be favorable if a light distribution generated by the lighting device is a dimmed light distribution, in particular a low-beam light distribution with an asymmetry region in the light-dark boundary of the low-beam light distribution.
    For example, it may be provided that the illumination device is set up to produce a dimmed light distribution, in particular a low-beam light distribution, in which the asymmetry region of the cut-off line of the low-beam light distribution is at 90 ° to the horizontal.
    For example, it is provided that the lighting device is adapted to horizontally and / or vertically move the entire dimmed light distribution, in particular the entire low beam distribution, or at least a portion of this light distribution.
    It can be provided that the lighting device is adapted to at least one light distribution, preferably a dimmed light distribution, in particular a low-beam light distribution, from individual light segments, e.g. horizontally next to each other or side by side and vertically one above the other lying light segments to build.
    It can be provided that the lighting device is designed as a motor vehicle headlight.
    It can also be provided that a motor vehicle headlight comprises one or more such lighting devices. In the latter case, each such illumination device preferably produces another dimmed light distribution.
    It can be expedient if the lighting device system comprises at least one further lighting device described above, which is at least one further lighting device, a right / left motor vehicle headlight or part of a right / left motor vehicle headlight.
    In such a lighting device system, it may be favorable if the at least one control device also controls the further lighting device, which is at least one further lighting device a right / left motor vehicle headlight or part of a right / left motor vehicle headlight such that in a lighting device system for right-hand / left-hand traffic left / right side mirrors of a vehicle traveling ahead when the dimmed light distribution is activated, in particular when the dipped beam distribution is activated, and / or when switching on the dimmed light distribution, in particular the dipped beam distribution, is not illuminated.
    In principle, a separate control unit can be provided for each lighting device (left / right) or each headlight. It is useful, however, usually when exactly one control device is provided for all lighting devices.
    Preferably, it is provided that the at least one control device controls the at least two lighting devices, i. the at least one left lighting device and the at least one right lighting device, synchronously controls.
    The activation of the at least one lighting device or of the at least one motor vehicle headlight or of the lighting device system can take place dynamically, i. the dimmed light distribution, in particular low-beam distribution, is permanently modified in accordance with the information of the at least one optical image acquisition system. The control can also be static, however, in that when a preceding vehicle is detected in the area illuminated by the unmodified light distribution, a certain area of the light distribution is not illuminated. Thus, there is only a switchover between the defined, unmodified and exactly one modified dimmed light distribution, in particular between two low-beam light distributions.
    Typically, e.g. the light distribution by 1 ° - 3 °, preferably about 2 ° pivoted - the modified Abblendlichtverteilung is thus the unmodified low beam distribution, by 1 ° - 3 °, preferably about 2 ° shifted. Or light segments are masked out such that the cut-off line is limited by a fixed amount, e.g. 1 ° - 3 °, preferably approx. 2 ° to the right or left shifted.
    One aspect of the present invention is thus that of a low beam distribution, i. a dimmed light distribution, which has an asymmetry region in the cut-off line, to shift the asymmetry region such that no glare of the occupants, in particular the driver of a preceding vehicle, in particular a car or a motorcycle, takes place or such Glare is reduced.
    In the following the invention is discussed in more detail with reference to the drawing. In this shows
    1 shows a situation for right-hand traffic with a vehicle in front and a low-beam distribution,
    FIG. 2 shows a situation for right-hand traffic with a preceding vehicle and a low-beam distribution with a 90 ° asymmetry, FIG.
    3 is a schematic view of a motor vehicle according to the invention with two motor vehicle headlights,
    Fig. 4 shows the situation of Figure 1 with a modified according to the invention
    Low beam distribution, and
    Fig. 5 shows the situation of Figure 2 with a modified according to the invention
    Low beam.
    Figure 1 shows the view from a motor vehicle forward to the road. Shown is the situation for legal traffic. Before the - not shown -, located on the right side of the road motor vehicle is a preceding vehicle 50, in particular a at least two-lane passenger car (PKW). This car 50, which is thus seen from behind, has a left side mirror 51 and a right side mirror 52.
    The motor vehicle, from which the view is shown to the front, has a
    Lighting device system comprising two motor vehicle headlights, a left and a right headlamp, which, in the illustration shown a
    Low beam distribution ABV1 generated.
    The low-beam distribution ABV1 has a light-dark boundary HD1, which has an asymmetrical section HDasl, which in a known manner is used, for example, as rises below about 45 ° to the horizontal.
    As can be seen, the right-hand outside mirror 52 of the preceding vehicle can possibly be illuminated, in particular by the asymmetry region of the low-beam light distribution ABV1, which can lead to dazzling of the occupants of the preceding vehicle 50, in particular of the driver.
    FIG. 2 shows a similar situation as in FIG. 1, with the difference that here the low-beam distribution ABV2 has an asymmetry section HDas2 in the bright-dark boundary HD2, which increases below 90 °.
    As can be clearly seen, the risk of the right-hand exterior seal 52 of the vehicle traveling in front of the vehicle, in particular a car, being illuminated is still significantly greater in the case of such low-beam light distributions than in the situation illustrated with reference to FIG.
    FIG. 3 shows an exemplary motor vehicle 10 according to the invention with which such glare can be reduced or completely prevented as described.
    The vehicle 10 has a lighting device system 1, which consists of a right and a left headlight 2, 4. Each headlamp 2, 4 comprises at least one illumination device 3, 4, which is designed to generate a low-beam light distribution as described with reference to FIG. 1 or FIG.
    Furthermore, a control device 7 for controlling the two lighting devices 3, 5 and / or generally the two headlights 2.4 is provided.
    In addition, an object recognition system, preferably an optical image acquisition system 6, typically a camera, is provided, which monitors the environment ahead of the motor vehicle 10 (see FIGS. 1 and 2).
    The control device 7 receives information from the camera 6, in particular as to what the camera 6 "detects" in front of the vehicle 10, and on the basis of this information, the control device can control the lighting devices 2, 4 accordingly.
    If the camera 6 now recognizes a preceding vehicle 50, and the right-hand side mirror 52 of this vehicle 50 would be illuminated by the defined low-beam distribution ABV1, ABV2, as shown in FIG. 1 or FIG. 2, then the control device 7 can be at least one of the two, preferably both, lighting devices 2, 4 such that a modified Abblendlichtverteilung ABVT, ABV2 'is generated, in which the right side mirror 52 is not illuminated.
    Such non-dazzling, modified Abblendlichtverteilungen are shown in Figure 4 and Figure 5, wherein Figure 4 is a modification of the low beam ABV1 of Figure 1 and Figure 5 shows a modification of the low beam ABV2 of Figure 2.
    Preferably, the camera 6 observes the environment permanently or is turned on when switching on the low-beam distribution, so that the light distribution can always be set optimally according to the invention - both when switching on and during operation.
    It may be sufficient if only one of the two headlights or one of the two lighting devices is controlled according to the invention. In the case of right-hand traffic, the left-hand headlight or the lighting device 5 arranged in the left-hand headlight is typically the more critical, so that at least this is controlled according to the invention.
    Preferably, however, both lighting devices 3, 5 or headlights 2, 4 are driven according to the invention. In this case, a separate control device can be provided for each lighting device / each headlight, but preferably both lighting devices 3, 5 or headlights 2, 4 are controlled by a common control device 7, which receives information from the camera 6.
    It is preferably provided that, depending on the situation that is detected with the camera 6, the defined light distribution is modified to the same extent that no glare occurs exactly or the glare is sufficiently reduced. This results in a large number of different modified light distributions, depending on the situation in front of the motor vehicle.
    Figure 1 shows e.g. the unmodified, defined low-beam distribution ABV1. This is pivoted according to the invention to the right, so that the modified
    Low beam ABVl 'according to Figure 4 results. The shape of the low-beam distribution has not changed significantly and may only be slightly distorted, but has essentially changed only its position in front of the motor vehicle (see the position of the asymmetry HDasl and the lower left of the light distributions ABV1, ABV1 ').
    Such a shift of the illumination light distribution or, in general, a (dimmed) light distribution can be e.g. well with a lighting device, which is set up to realize a cornering light implement.
    In such a lighting device, it may be e.g. to act a projection system, such as a module, in particular a projection module comprising reflector and / or lens, light source and, where appropriate, means for generating a cut-off line, e.g. a shadow element. To realize the cornering light, the entire
    Module / projection module to be pivoted about a vertical axis, or only parts thereof (in particular reflector or lens) are pivoted about such an axis, whereby the generated light image can be pivoted to the left or right.
    This can be used for the present invention by, for the purposes of the invention, such pivoting on demand even when driving straight ahead, or when cornering a greater or lesser pivoting of the module (or parts thereof), depending on the position of a preceding vehicle, in particular its right exterior mirror takes place.
    FIG. 4 shows, for example, a pivoting of the low beam distribution ABV1 from FIG. 1 by approximately 2 ° to the right so that the low beam distribution ABV1 'results.
    In such a pivoting of the light distribution and the maximum of the light distribution is mitverschwenkt accordingly.
    Figure 2 shows e.g. the unmodified, defined low-beam distribution ABV2. This low-beam distribution ABV2 is made up, for example, of individual light segments, e.g. horizontally next to each other or next to each other and vertically behind each other lying light segments, constructed. Each light segment is independently controllable, e.g. in that each light segment is generated using its own light source, for example its own LED, and the individual light sources can be controlled independently of one another, in particular switched on and off.
    By way of such a segmented light distribution, in particular a low-beam distribution ABV2 with a 90 ° asymmetry HDas2 of the bright-dark boundary HD2 can be generated.
    For erf indungs modern modification of this Abblendlichtverteilung ABV2 now those light segments are turned off, which would illuminate the right side mirror 52 of the preceding vehicle 50, so that the low beam distribution ABV2 'shown in Figure 5 results. This differs from the unmodified, defined low-beam distribution ABV2 only in that the asymmetry region HDas2 'of the bright-dark boundary HD2' now lies further to the right, so that the exterior mirror 52 is unlit. Otherwise, the low beam distribution is unchanged, the maximum remains here in the middle of the road.
    The figures describe the situation for countries with legal relations. For left-hand traffic, the opposite directions apply.
