Description

Technical area

The present invention relates to a headlight system for a motor vehicle, a method for operating such a headlight system and an associated computer program product.

Headlight systems have always been part of the basic equipment of motor vehicles. Thus, various headlight systems or headlight configurations and configurations are provided in particular in the area of a vehicle front. For example, common motor vehicles on a low beam, high beam and fog lights. Furthermore, there are adaptive headlight systems that can vary the generated light beam in terms of its orientation and intensity depending on steering impact. There are also cornering lights, which illuminate the curved area separately, especially when driving around tight bends.

So is for example from the DE 10 2008 008 880 A1 a vehicle lighting system with a detection device is known, which is designed to detect a solid angle in which a road user is located. In this case, a light emitting device for emitting signal light with a spatial angle-dependent spectral distribution and / or a space angle-dependent intensity is also provided. A relevant solid angle in which a road user, in particular a predetermined type or class, such as a vehicle, a pedestrian or an animal, can be determined, for example, by means of environmental sensing methods. From the data thus obtained can then be determined a relevant solid angle or a relevant emission direction for the emission of the signal light.

The emission direction can be directed to the extent directly or indirectly to the road user. Furthermore, if the objects in question are illuminated with a signal light based on the detection by the vehicle lighting system, they can be better recognized by the driver and / or have a signaling effect for a road user.

The provision of a signal light, which is typically only to be activated temporarily, can purposefully alert the driver of the vehicle to possible danger areas. A comparatively abrupt or sudden change in intensity in a relevant solid angle range can possibly irritate the driver, but also other road users.

It is therefore an object of the present invention to provide a headlamp system for a motor vehicle, which in particular provides a permanent and continuous assistance function for the driver of a motor vehicle, and which is further adapted to increase the visual perception ability of the driver continuously and permanently. In addition, the headlight system should have the least possible disruptive effects on other road users or oncoming traffic. The headlamp system should be characterized by a simple and space-saving and cost-effective design and fall back on advantage advantageously largely existing in the motor vehicle components.

This object is achieved with a headlamp system according to claim 1, with a motor vehicle according to claim 11, further comprising a method for operating a headlamp system according to claim 12 and with a computer program product according to claim 14. Advantageous embodiments are in each case the subject of dependent claims.

The extent proposed headlamp system is provided for a motor vehicle and designed accordingly. It has an environment detection device, which is designed to determine a lying in the direction of travel in front of the motor vehicle lane. Furthermore, the headlamp system has at least one motor vehicle headlight, which is preferably arranged on the vehicle front, and which is designed to act on the lane determined or determined via the surroundings detection device and at least one peripheral region adjacent thereto in the vehicle transverse direction (y) with light of different spectral composition.

In this case, the headlamp system is designed, in particular, to apply at least the lane and an adjoining peripheral region to light of different spectral composition as permanently and continuously as possible.

The headlamp system provides a targeted spectral and spatial as well as adaptive change of the light emitted by the at least one headlight. By means of a spatial distribution, for example a light cone that can be generated by the headlight in at least two partial light cones of different spectral composition, the perception ability of a driver of the motor vehicle can be selectively changed, preferably increased, at least in the areas acted upon by the respective partial light cones.

Investigations have shown that the spectral perception of the human eye is not spatially constant, but that the spectral perception of the human eye approximately in the edge region of the field of vision differs from the perception ability in a central region of the field of view.

Since the at least one motor vehicle headlight is designed to spatially change the spectral composition of the generated light as a function of the determined traffic lane, in particular to adapt it to the spatial spectral perceptibility of the human eye, the effective perceptibility can be achieved by the spatial-spectral change of the light generated by the headlamp be increased by the driver or an operator.

As a result of the targeted spectral change of the spatial spectrum of the light which can be generated by the motor vehicle headlight, the driver's perception ability can thus be advantageously increased even without a substantial change in the intensity of the light. Oncoming traffic or other road users are less affected by this, as would be the case with a pure intensity change of the headlight.

According to an advantageous embodiment of the motor vehicle headlamp is further adapted to act on the detectable or detectable via the surroundings detection device lane and the at least one peripheral region simultaneously with light of different spectral composition or distribution. For this purpose, the at least one motor vehicle headlight typically has a plurality of light sources, in particular light-emitting diodes (LED) or comparable laser light sources. The motor vehicle headlight may in this case be designed, in particular, to generate white light, the spectral distribution of which, however, can be varied variably within predefined regions.

The motor vehicle headlight may, for example, have a plurality of red, green and blue (RGB) light-emitting diodes, which may be arranged in the manner of a two-dimensional grid, for example. In this case, the individual light sources can be individually controlled in order to specifically change the spectral composition of the light beam that can be generated by the motor vehicle headlight, but also to vary the transverse and spatial intensity distribution, in each case adapted to the ascertainable traffic lane.

The size and orientation of the partial light cone can also be variable depending on the determined lane or a determined environment situation. Thus, the solid angle areas coinciding with the respective partial light cones can be dynamically exposed to light of different spectral composition.

According to a preferred refinement, the headlight system or the at least one motor vehicle headlight is designed to continuously illuminate the lane and the at least one peripheral area. In that regard, the headlamp system can provide a type of high beam or low beam with spatially varying spectral composition.

Continuous illumination of the traffic lane and of the at least one, typically laterally adjacent, region pursues an approach which opposes a signal light effect. The predominantly continuous illumination of the traffic lane and of the peripheral area adjacent thereto does not have a temporary signal effect to the destination, but primarily serves to continuously draw the driver's attention to a spectrally altered solid angle range. Impairments or influences on the oncoming traffic or other road users can thereby be reduced to a minimum.

According to a further embodiment, the motor vehicle headlamp is designed to divide the entire, in the direction of travel in front of the motor vehicle area in at least one central illumination zone and two mutually adjacent peripheral peripheral illumination zones, which are each acted upon by light of different spectral composition. In that regard, the motor vehicle headlight can be designed, in particular, as a surface radiator for generating a comparatively divergent light cone, which can largely illuminate the full area of the area of a roadway in the direction of travel in front of the motor vehicle and accordingly act on light.

The central illumination zone preferably correlates with the lane that can be determined by the surroundings detection device. In this case, the central illumination zone can largely coincide with the determinable traffic lane in terms of its size and course, or else concern a central region of the driver's field of vision which is widened approximately in the vehicle transverse direction (y), in which the detectable or determinable traffic lane of the motor vehicle runs. In this case, the lane can either be an imaginary line, which represents an ideal driving line of the motor vehicle. However, it is also conceivable that the width of the lane correlates with the actual width of the motor vehicle.

In particular, it is conceivable that the traffic lane or the central lighting zone coincides with a vehicle center and extends approximately to a width of 30%, 50% or 80% of the vehicle transverse extent (y). The at least one peripheral region adjoins this, viewed in the vehicle transverse direction (y), to the outside. If, for example, a peripheral lighting zone is provided on each side of the central lighting zone, its width extends to approximately 35%, 25% or 10% of the extent of the motor vehicle in the vehicle transverse direction (y).

That consideration relates in particular to a spatial light distribution lying directly in front of the motor vehicle. The central lighting zone as well as the adjoining peripheral lighting zones can, with respect to the direction of travel, have a spatially divergent propagation characteristic, so that, of course, outside of the motor vehicle lying edge regions of a roadway can be sufficiently illuminated.

It is conceivable here that the partial light cones of the at least one motor vehicle headlight that can be assigned to the individual illumination zones have different propagation characteristics. For example, it is conceivable that a central illumination zone that can be illuminated by two motor vehicle headlights has a profile that converges relative to the direction of travel, while the peripheral illumination zones adjacent thereto have a laterally diverging structure in the direction of travel. Also, a reversed light distribution structure with a diverging central illumination zone and with converging peripheral illumination zones is conceivable.

In this way, a different spatial spectral light distribution can be obtained directly in front of the motor vehicle, for example in the near field, than is the case for areas located further away from the motor vehicle.

According to a development, the headlamp system can also be designed to dynamically change the boundaries between the central illumination zone and the at least one adjoining peripheral illumination zone as a function of the lane determination that can be provided via the surroundings detection device. Thus, the spatial spectral light distribution when driving straight ahead compared to curve areas can be changed. In this case, it is conceivable, in particular, that curve-dependent different spatial boundaries between the central lighting zone and adjacent peripheral lighting zones can be implemented. By a dynamic, in particular driving situation-dependent change of the boundaries between the lighting zones, the size ratios of the lighting zones can be variably adapted to different driving situations in accordance with an environment detection.

According to a further embodiment, the headlamp system is further configured to change the boundaries between the central illumination zone and the at least one adjoining peripheral illumination zone in dependence on a condition of the surroundings detectable via the surroundings detection device. For example, it can be determined via the surroundings detection device whether and to what extent objects are located on the roadside. Also, z. B. are determined in particular when driving overland, whether the motor vehicle is located approximately on a free area or in a forest area. Accordingly, the emission characteristic of the at least one motor vehicle headlight can be changed dynamically and universally to improve the perception ability of the driver.

Other application scenarios can detect, for example, a journey through a tunnel, so that here too the spectral radiation characteristic of the at least one headlight can be adapted to the environment, in particular to comparatively well reflecting tunnel walls.

According to a further embodiment, the headlight system may further be configured to apply light of different or variable intensity to the central illumination zone and at least one of the adjacent peripheral illumination zones. By a relatively large-scale intensity change in one part or in the entire central or peripheral illumination zone, the driver's attention can be directed to peripheral or central areas of his field of vision.

Finally, it is provided according to a further advantageous embodiment that the at least one headlamp is adapted to act on the lane with light of a first spectral composition, which is shifted from a second composition in a shorter wavelength spectral range, wherein the peripheral region with light of the second spectral Composition is acted upon. As a result, for example, the central illumination zone can be exposed to a blue-shifted white-light spectrum, while adjacent peripheral areas can be acted upon by, for example, light with a red or yellow-shifted spectral composition.

Depending on the situation, however, a reverse constellation is also conceivable in which the peripheral illumination zone with a blue or violet shifted white light spectrum, the central illumination zone but are acted upon by a red or yellow shifted white light spectrum.

In this way, the perception ability of the driver in the central lighting zone as well as in the peripheral lighting zones can be increased in a targeted and situation-adapted manner.

In that regard, the headlamp system can virtually produce a spectrally altered spot in a lying in the direction of travel in front of the vehicle area in the field of view of the driver, which stands out from the ambient lighting. The spectral variation or spectral variation of the light spot that can be generated by the motor vehicle headlight preferably moves within different white light spectra. In this case, provision is made in particular for the spectrum of the light which can be generated by the headlight to be changed in the direction of short-wave wavelength ranges, for example into blue or bluish, or else in the direction of longer-wave spectral ranges, such as to yellowish-reddish.

Overall, however, the range that can be generated by the motor vehicle headlight should move within a multiplicity of conceivable white-light spectra, so that legal requirements with regard to a permissible spectral variance of motor vehicle front headlamps are met.

According to a further embodiment, the headlamp system is designed to apply at least one, with respect to the determined viewing direction peripheral solid angle range with light of a first spectral composition. In this case, provision is made in particular for the first spectral composition to be displaced approximately into the short-wave range, so that the areas lying in the peripheral field of view are acted upon, for example, by a white light shifted into the blue spectral range.

Particularly in the peripheral or peripheral areas of the visual field, the eye has an increased sensitivity to shorter wavelength spectral components. By adaptively imparting a blue-shifted spectral composition to the peripheral solid angle range of the driver's field of view, the peripheral perception of the driver in that range can be improved. Thus, the driver's perception of any obstacles in the peripheral area of the visual field can be advantageously increased.

According to a further embodiment, the at least one headlight has a plurality of individually controllable light sources, in particular light-emitting diodes (LED).

In a further preferred refinement, the headlamp system can furthermore be coupled to at least one driver assistance system or it has one. The headlight system is designed to change the spectral composition of the light and / or a spatial angle range of the headlight to be acted upon by the spectral composition as a function of at least one parameter of the driver assistance system.

As a driver assistance system, for example, lane keeping assistance systems and navigation systems but also, for example, an anti-lock braking system (ABS) or an electronic stability program (ESP) come into question.

By coupling the headlamp system with a navigation system, for example, it is conceivable that the spectral composition of a light cone as well as the solid angle range of the motor vehicle headlight provided with the corresponding spectral composition may be e.g. B. receives approach to an intersection advantageous for the perception of the crossing situation composition.

For example, it may be provided that the geometry and size of the spectrally altered solid angle range of the headlamp is at least partially decoupled from the determined lane in an intersection situation in order, for. B. to stop the driver to look at the crossing area.

In that regard, the parameters of a driver assistance system can also act to selectively influence the viewing direction of the operator. Since the spectral composition in the intended solid angle range can deviate only slightly from a normal white light spectral distribution, it is conceivable that the influence of the driver by the adaptive headlight system rather unconsciously than consciously perceptible by the driver.

Furthermore, by designing the headlamp system to constantly apply a spectrally altered or slightly spectrally shifted light composition to the peripheral area of the visual field, the driver's eye and viewing habits can also adapt to the spectrally and spatially inhomogeneous composition of the headlight light.

The variation of the spectral composition of the light which can be generated by the at least one motor vehicle headlamp can be compared with respect to Center of gravity, that is, with respect to a mean or averaged spectral line to vary by at least 10 nm, 20 nm, 50 nm or up to 100 nm or 150 nm. For example, the centroid wavelength may divide the spectral distribution into two regions of equal integral power.

Finally, according to a further independent aspect, a motor vehicle with a previously described, preferably designed as low beam and / or high beam headlight system is provided.

Independently of this and according to a further aspect, a method is provided for operating a headlight system described above, wherein in a first step a lane in front of the motor vehicle is determined and in a subsequent step the lane detectable or determinable by means of an environment detection device and at least one in the vehicle transverse direction (y) adjoining thereto region are exposed to light of different spectral composition by means of at least one motor vehicle headlight.

In this case, the method can be implemented in particular with the headlamp system described above. In that regard, all features and advantages of the headlamp system apply in a corresponding manner also for the said method; and vice versa.

According to a further development of the method, it is further provided that the entire area lying in front of the motor vehicle in the direction of travel is subdivided into a central illumination zone and into at least two peripheral illumination zones adjacent thereto, which are each exposed to light of different spectral composition. The at least one and preferably a number of individual light sources having motor vehicle headlights is in this case driven such that it produces a, several partial cone having light cone, wherein a correlating with the peripheral illumination zone partial cone receives a different spectral composition than z. B. correlating with the central illumination zone partial cone of light.

In this case, the distribution of the light cone or partial cone of light can be effected dynamically and situation-dependent, in particular as a function of the lane determined or ascertainable via the surroundings detection device.

According to a further aspect, a computer program product for operating a headlight system, in particular a headlight system described above, is further provided. In this case, the computer program product has program means for determining a lane in front of the motor vehicle in the direction of travel by means of an environment detection device. Furthermore, program means are provided for acting on the lane and at least one area adjoining the vehicle transverse direction (y) with light of different spectral composition by means of at least one motor vehicle headlight.

In this case, the computer program product can be implemented in particular with the headlamp system described above. In that regard, all features and advantages of the headlamp system apply in a corresponding manner for the computer program product.

According to a further independent aspect, an apparatus for operating a headlamp system, in particular a headlamp system described above is further provided. In this case, the device has means for determining a lane in front of the motor vehicle in the direction of travel by means of an environment detection device. Furthermore, means for acting on the traffic lane and at least one area adjoining the vehicle transverse direction (y) with light of different spectral composition by means of at least one motor vehicle headlamp are provided. The device for operating the headlamp system can be implemented in particular with the previously described headlamp system. In that regard, all features and advantages of the headlamp system apply in a corresponding manner for the device for the operation of the same.

Detailed description

In 1 is a schematic representation of a motor vehicle 10 with a passenger compartment 12 shown, which in the area of its vehicle front left and right at least a motor vehicle headlight 14 . 16 having. Both headlights 14 . 16 are each for generating a light cone 34 . 44 formed, which in each case in partial cone 30 . 32 as well as partial cone of light 42 . 40 is divisible. As in 1 indicated, have the partial light cone 30 . 32 of the light cone 34 a different spectral composition. The same applies to the two partial cone of light 42 . 40 of the light cone 44 to.

The vehicle 10 This is on a carriageway that is to the left of a median strip 20 and to the right of a lane boundary marker 18 is limited.

That the headlights 14 . 16 having headlight system 50 as it is schematic in. 3 has an environment detecting device 52 , for example in the form of a front camera or a front camera system. Coupled with this, the headlamp system 50 an evaluation unit 54 auf, by means of which about the camera recorded image data for determining a in the 2 sketched lane 28 are evaluable.

The from the evaluation unit 54 Generable information regarding the lane 28 can be a hereby coupled control unit 56 be fed, by means of which at least one, preferably both motor vehicle headlights 14 . 16 are controllable. The evaluation unit 54 and the sketched control unit 56 are not necessarily structurally separate. Rather, the evaluation unit 54 and the control unit 56 be integrated in a single and common computer-aided module, such as in a microcontroller. The headlamp system 50 In this case, a control loop is typically provided which, based on visually detectable camera data, generates lane information via which at least the spatially spectral emission characteristic of the motor vehicle headlights 14 . 16 is controllable.

It is hereby provided in particular that the headlights 14 . 16 for full-surface illumination of one in the direction of travel 36 in front of the motor vehicle 10 lying area are formed. In particular, the front of the vehicle 10 lying area by means of the headlamp system 50 in one, about the lane 28 coincident or the lane 28 enclosing central lighting zone 24 and in at least two opposite and laterally adjacent peripheral illumination zones 22 divisible, as for example with reference to the in 2 shown field of view of the driver is indicated.

In this case, it can be provided in particular that the two partial light cones facing each other 32 . 42 the headlight 14 . 16 have a first spectral composition which differs from a spectral composition of the partial cone of light which adjoins the vehicle transverse direction (y) 30 . 40 different. The two outer partial cone of light 30 . 40 the two motor vehicle headlights 14 . 16 are in the 1 and 2 especially intended to the peripheral lighting zone 22 to illuminate, while the two inner partial light cone 32 . 42 intended and intended, which are approximately in the center, with the lane 28 coincident or the lane 28 enclosing central lighting zone 24 largely to illuminate the entire surface.

The central lighting zone 24 and the peripheral illumination zones 22 can each be spectrally shifted relative to a comparatively neutral white light spectrum. For example, the central lighting zone 24 be displaced into the bluish or violet, while the peripheral illumination zones 22 can be shifted to the red-yellowish. Accordingly, the driver's perceptual ability may be specific to the central lighting zone 24 be increased. Other, or reverse driving the headlamps and associated spectral shifts of the light cone 34 . 34 or the associated partial cone 30 . 32 such as 40 . 42 are also conceivable, so as to apply to the roadside edge, if necessary, with a spectrally shifted in the shorter wavelength range wavelength light beam, while the lane can be acted upon by a long-wave shifted spectrum.

In contrast, it is also conceivable that only one of the lighting zones 24 . 22 spectrally to a neutral white spectral distribution, either blue or red shifted.

The two peripheral lighting zones 22 can synchronously in time, but also completely independent of each other with partial light cones 30 . 40 be applied to different spectral composition. It is also conceivable, the entire field of vision of the driver, approximately symmetrically between a central lighting zone 24 and adjacent peripheral lighting zones 22 divide. Depending on the driving situation and depending on the determination of the traffic lane 28 via the surroundings detection device 52 but also spatially asymmetrical lighting profiles can be realized.

Also, the boundaries between the partial light cones 30 . 32 such as 42 , 40 can be configured variably variable. The partial light cones 30 . 32 . 42 . 40 as well as the light cone formed thereby 34 . 44 may have a different propagation characteristic. For example, the two partial cones provided in the central area can be used 32 . 42 one related to the direction of travel 36 of the motor vehicle 10 Provide divergent or converging radiation characteristic, by a corresponding propagation characteristic of the peripheral peripheral partial cone 30 . 40 is supplemented.

The headlamp system 50 can also use a driver assistance system 58 be coupled, which can provide additional information about the current driving situation of the motor vehicle and the automotive environment. If the driver assistance system 58 For example, designed as a navigation system, the headlamp system can 50 also taking into account provided navigation data, the spectral composition and the spatial spectral distribution of the headlights 14 . 16 producible light cone 34 . 44 change in a variable and situational way.

In 4 Finally, is a flowchart of the method for operating the headlamp system 50 outlined. In a first step 100 is by means of the detection device 52 the current lane 28 it motor vehicle 10 determined or determined by computer. The recorded lane 28 can then in a subsequent step 102 evaluated and used to control the headlights 14 . 16 be used. If there are no changes or only insignificant changes in comparison to a lane-related headlight configuration performed previously in terms of time, this has essentially no effect on the control and operation of the motor vehicle headlights 14 . 16 ,

The procedure jumps to the step 100 back. Only when the evaluation 102 a change in the lane 28 registered, the procedure goes to step 104 continued. The change of the lane 28 is then used for spectral adaptation or spectral change of at least one headlight 14 . 16 used.

In this case, it is provided in particular that a predetermined one or that one with the respective lane 28 coincident or the lane exhibiting solid angle range of the motor vehicle headlight 14 . 16 undergoes a spectral adjustment. It can be provided in this case that a previously illuminated by a standard default solid angle range is illuminated as a result of the lane change with a changed spectral composition. On the other hand, it is conceivable that a spectrally altered solid angle range together with the changing lane 28 in the field of vision of the driver mitwandert.

Once a spectral change of the headlamp in step 104 has been set, the process jumps back into the step 100 to the lane 28 continuously track or determine. The control loop is then re-run.

The illustrated embodiments show only possible embodiment of the invention to which further numerous variants are conceivable and within the scope of the invention. The exemplary embodiments shown are in no way to be construed as limiting the scope, applicability or configuration possibilities of the invention. The present description merely shows the person skilled in the art a possible implementation of an exemplary embodiment according to the invention. Thus, the most varied modifications can be made to the function and arrangement of elements described without thereby abandoning the scope of protection or its equivalents as defined by the following claims.
