[0001] Vision system for a vehicle

[0002] Description

[0003] The invention relates to a vision system for a vehicle, comprising a recording unit for recording image data of an external field of vision of the vehicle. The invention further relates to a mirror replacement system for a motor vehicle and a motor vehicle with such a vision system.

[0004] State-of-the-art vision systems for vehicles, particularly commercial vehicles, are known in which conventional exterior mirrors are supplemented or completely replaced by camera-monitor systems, as part of a so-called mirror-replacement system. The advantages include lower aerodynamic drag from the camera mounted on the outside of the vehicle compared to an exterior mirror, as well as convenience for the driver. The image captured by the camera is displayed on a monitor mounted in a location within the vehicle that is easily visible to the driver. Optionally, image data from multiple viewing areas can be displayed simultaneously on the monitor, giving the driver a good overview of the vehicle's surroundings.In addition, the image data captured by the camera is displayed largely undistorted on the monitor, whereas wide-angle mirrors, in particular, only provide the driver with a distorted image of the surroundings, making it difficult to assess the actual distance and size of objects in the vehicle's surroundings. It is also possible to display additional information useful to the driver on the monitor image, or to highlight obstacles.

[0005] However, there may be disadvantages when using such systems if the camera does not capture sufficiently good images due to low lighting conditions in the vehicle's surroundings.

[0006] The state of the art includes methods for post-processing image data that can brighten such images. However, these techniques have the disadvantage that image quality deteriorates, and important details of the vehicle's surroundings may no longer be sufficiently recognizable, or that image details may even be distorted by the post-processing.

[0007] While external light sources, such as bright spotlights or headlights, in the vehicle's surroundings can increase the amount of available light, they can sometimes cause problems with image quality. Spotlights from an angle unfavorable to the camera, for example, due to shadows cast from the side, can impair the quality of the recorded image data, as some areas are brightly lit, while obstacles in darker areas can be overlooked. Furthermore, unfavorable reflections from external light sources can lead to glare, which, in the worst case, can render the recorded image data unusable due to uneven lighting.

[0008] The invention is therefore based on the object of creating an improved technology for designing a vision system for a vehicle, which can avoid the disadvantages of conventional vision systems. In particular, the field of view presented is intended to enable improved safety during maneuvering of the vehicle, especially in unfavorable lighting conditions.

[0009] The problem is solved by the features of independent claim 1. Advantageous further developments are specified in the dependent claims and the description.

[0010] According to a general aspect of the present disclosure, a vision system for a vehicle is provided. The vision system comprises a recording unit, e.g., one or more cameras, for recording image data of an external field of vision of the vehicle. The vision system can, for example, be part of a mirror replacement system of a vehicle. The vision system further comprises a lighting unit for illuminating at least a partial area of ​​the external field of vision. The lighting unit is designed to emit light in the visible range. Furthermore, the vision system comprises a holder attachable to the outside of the vehicle, by which the recording unit and the lighting unit are held.

[0011] The lighting unit can illuminate the vehicle's outer field of vision when needed. Advantageously, the recording unit can record image data with improved light intensity and image contrast when external lighting conditions in the vehicle's surroundings are unfavorable. This can improve the image quality of the vision system. The risk of the driver misjudging proportions or overlooking obstacles due to poor lighting in the vehicle's surroundings can be reduced. A particular advantage of using a mount that holds both the recording unit and the lighting unit is that the lighting unit can be designed particularly efficiently and effectively to illuminate the outer field of vision. For example, the lighting unit can be positioned relative to the recording unit so that the recording unit's outer field of vision is illuminated from the direction from which the recording unit records the image data.Shadows and / or reflections on objects in the vehicle's surroundings caused by light incident from unfavorable angles relative to the recording unit can be more reliably avoided. Furthermore, positioning the lighting unit close to and / or adjacent to the recording unit allows the lighting unit to be designed particularly well to illuminate the recording unit's field of view. Overall, driving safety can be improved, especially during shunting in poorly or unevenly lit vehicle environments.

[0012] The external field of view captured by the recording unit can be and / or include a lateral and rearward field of view of the vehicle. Alternatively or additionally, the external field of view can include other external fields of view.

[0013] The mount can preferably be designed as a lateral extension arm and / or support arm, which has a fastening point at one end for attaching the mount to an exterior wall of the vehicle. Both the receiving unit and the lighting unit can be designed as separate components and fixed to the mount and / or integrated into it.

[0014] According to an advantageous embodiment, the lighting unit is designed to selectively generate and / or emit different light distributions, preferably different partial light distributions, in order to selectively illuminate different sub-regions of the external field of vision. In other words, the lighting unit can be controlled such that the light distribution generated by the lighting unit can be changed in order to adapt which sub-region of the external field of vision is preferably illuminated and how.

[0015] A (partial) light distribution generated by the lighting unit can be characterized by its beam direction and beam profile. The different partial light distributions can differ, for example, in their beam direction and / or beam profile. Advantageously, it is possible to specifically adjust which sub-area or sub-areas of the external field of vision are currently illuminated by the lighting unit. A partial light distribution is a light distribution in which at least a sub-area of ​​the external field of vision is illuminated, but at least one sub-area is also not illuminated or is only illuminated with lower intensity. Furthermore, a light distribution that can be selectively generated by the lighting unit can comprise a light distribution in which the entire external field of vision is illuminated.

[0016] Excluding a portion of the illumination can be advantageous, for example, if a highly reflective object in the vehicle's surroundings could result in overexposed image data if illuminated at maximum intensity. Therefore, image quality can be improved if the portion of the outer field of view containing this object is not illuminated or is illuminated at a reduced intensity.

[0017] Alternatively, a single section of the outer field of vision can be illuminated, while the rest of the outer field of vision is not illuminated or is illuminated only with low intensity. This variant can be particularly advantageous when a focus is to be placed on specific areas of the vehicle and / or the vehicle's surroundings, as the driver's attention is drawn specifically to the illuminated area.

[0018] The lighting unit can be designed as a so-called matrix lighting system. The lighting unit can have a matrix module for generating different light or partial light distributions. Such matrix lighting systems or matrix modules are known from practical use as light sources for vehicle headlights.

[0019] The matrix module can comprise a plurality of light sources and / or light deflection elements, such as mirrors, arranged in columns and / or rows, preferably in a single plane. The matrix module can be designed as an LED matrix module comprising LED light sources.

[0020] In order to generate the desired partial light distribution, the individual light sources can be activated and / or deactivated independently of one another. Preferably, the intensity of the individually activated light sources can also be adjusted independently of one another. By specifically activating and deactivating the individual light sources, partial areas of the outer field of view can be illuminated with maximum intensity, while other partial areas can be excluded. Activation with reduced intensity enables softer, and thus more pleasing to the eye, transitions between illuminated and unilluminated areas. In addition, the brightness of illuminated partial areas can be reduced in order to increase the image quality of the recorded image data. If light deflection elements are used to generate the partial light distribution, the illumination unit preferably further comprises at least one light generation unit, e.g.At least one laser diode used to illuminate the light deflection elements. The light deflection elements can then be positioned so that they only direct the light into the outer light field when the corresponding sub-area is to be illuminated.

[0021] In a further embodiment, the recording unit is surrounded on both sides by elements of the matrix module. This means that when the mount is mounted on the vehicle, the matrix module comprises at least one element that is closer to the vehicle than the recording unit and at least one element that is farther from the vehicle than the recording unit. This can improve the targeted illumination of sub-areas of the external field of view.

[0022] According to a further embodiment, the vision system further comprises a display unit and an input unit for a driver of the vehicle. Furthermore, the vision system comprises a control unit that is or can be brought into signal communication with the display unit, the input unit, the recording unit, and the lighting unit. The control unit is designed to display image data of the recorded field of view on the display unit and to activate the lighting unit when a predetermined activation condition is met. The control unit can thus be used to specifically control when the lighting unit is activated, i.e., when it generates light to illuminate the outer field of view.

[0023] According to one embodiment, the predetermined activation condition can be met if the control unit detects a activation command via the input unit. This allows the driver to decide for themselves whether and how they want to activate the lighting unit. This can be done, for example, based on the driving situation and / or the prevailing lighting conditions and / or personal preferences. In other words, the lighting unit can be specifically switched on precisely when the driver actually needs it. If the lighting unit is not needed, the driver can deactivate it, for example, to prevent dazzling other road users.

[0024] Additionally or alternatively, the predetermined activation condition can be met if the control unit determines that the current time of day and / or current ambient lighting conditions indicate poor visibility and the vehicle is performing a maneuvering maneuver. In this case, the lighting unit is (automatically) activated if, due to the prevailing conditions, it leads to an improvement in the recorded image data. The advantage of this design variant is that the driver does not have to worry about activation or deactivation, thus reducing driver distraction. Restricting activation to the maneuvering situation can reduce the risk of dazzling other road users.

[0025] According to a further embodiment, the control unit is further configured to optionally illuminate the external field of vision completely and / or across its entire surface or only a partial area thereof. The input unit can preferably comprise a button for activating the complete and / or across-surface illumination. A button can be actuated quickly, precisely, and intuitively, particularly while driving, so that the driver is not distracted, or is only minimally distracted, by operating the vision system. Particularly in conjunction with the option of full-surface illumination, the button can therefore be particularly advantageous if the driver wishes to quickly obtain a quick overview of the external field of vision or a large area of ​​the vehicle's surroundings.

[0026] In a further embodiment, the control unit is further configured to display a selection tool for selecting at least one illumination point in the field of view on the display unit. The illumination point can be a point (illumination point) or an area (illumination area) of the recorded field of view, which, for example, the driver wishes to keep in view and have illuminated by the lighting unit. For example, a partial area of ​​the vehicle within the outer field of view and / or a location in the vehicle's surroundings, e.g., an obstacle or a parking space, can be selected as the illumination point using the selection tool. The at least one illumination point can be specified using the selection tool by actuating the input unit.

[0027] Furthermore, the control unit is designed to determine the at least one lighting location in response to the actuation of the input unit and to control the lighting unit such that a partial area of ​​the external field of vision comprising the at least one lighting location is illuminated. In this way, the driver can select one or more locations on the vehicle or the vehicle's surroundings to be illuminated by the lighting unit. This is particularly advantageous if, due to unfavorable lighting conditions in the vehicle's surroundings, the quality of the recorded image data can be improved by illumination using the lighting unit, and / or if the driver wishes to focus his attention on specific locations on the vehicle or the vehicle's surroundings using the illumination.

[0028] In an advantageous development, the at least one illumination point comprises a first point, which is referred to below as the focus point. The defined focus point is tracked on the display unit as a function of a position of the recording unit relative to the focus point, preferably during a maneuvering operation of the vehicle. In other words, the partial area (image section) displayed on the display unit by the control unit can be adjusted such that the currently displayed partial area (image section) always at least partially includes the defined focus point, even if the position of the recording unit changes relative to the focus point. This is particularly advantageous if the vehicle has a front vehicle part, e.g. a towing vehicle, and a rear vehicle part, e.g.a trailer or semi-trailer, wherein the front and rear vehicle sections can be pivoted relative to one another about a vertical pivot axis. Advantageously, the lighting point is simultaneously tracked, i.e., the light distribution generated by the lighting unit is adjusted as needed so that the focal point always remains illuminated during tracking. This allows the lighting point illuminated by the lighting unit to be reliably illuminated, even if the position of the lighting unit changes relative to the lighting point, e.g., during maneuvering.

[0029] The relative position of the recording unit to the focal point can be determined based on driving information of the vehicle, e.g., speed and steering angle. Additionally or alternatively, techniques from the field of image recognition can be used to track the specified focal point. A particular advantage of this embodiment is that it allows the driver of the vehicle to select any point in the recorded field of view that they wish to keep in view, e.g., in order to be able to safely carry out an upcoming maneuver, as the focal point. This point then remains illuminated and / or on the display of the display unit regardless of the movement of the vehicle. According to a further embodiment, the at least one illumination point comprises a second point, which is referred to below as the zoom point.The control unit is further designed to provide a magnification function by means of which the specified zoom point can be displayed in an enlarged manner on the display unit.

[0030] In normal ferry operations, the driver often wants a relatively large area of ​​the recorded field of vision to be displayed on the display unit in order to obtain a good overview of the vehicle’s surroundings at a glance. This allows the driver to proactively adapt their driving style to the surroundings and thus enable safe and accident-avoidant driving. However, it can happen that certain areas of the vehicle or the vehicle’s surroundings require special attention at short notice. On a display unit that shows image data from a relatively large section of the recorded field of vision, these areas could be comparatively small and difficult for the driver to recognize, particularly in unfavorable lighting conditions. This vision system advantageously gives the driver the option of displaying an area that is relevant to the current driving situation, e.g.During a shunting maneuver, a particularly relevant or critical area in the field of view that requires special attention can be selected as a zoom point and, if necessary, displayed in an enlarged format. This makes details of this zoom point more easily visible, particularly in combination with targeted illumination by the lighting unit. To implement the magnification function, the control unit can be configured to zoom in on the corresponding area of ​​the field of view on the display unit.

[0031] In a preferred development of this, the input unit comprises a zoom control element, preferably a button, for activating the magnification function. The control unit is designed to activate the magnification function in response to actuation of the zoom control element. This provides the driver with a particularly straightforward way of activating the magnification function precisely when needed. A button can be actuated quickly, precisely, and intuitively, particularly while driving, so that the driver is not distracted, or only minimally distracted, by operating the vision system.

[0032] In a further embodiment, the control unit is configured to store the at least one selected lighting location, preferably in a non-volatile memory and / or together with data relating to a removable trailer of the vehicle. This allows the driver to save lighting locations that may also be relevant for performing subsequent maneuvers and easily recall them later, as needed, without having to re-adjust the lighting location. If a non-volatile memory is used as the storage medium, the lighting location can be recalled even after the vehicle has been completely shut down or parked and then switched on again.

[0033] The function of storing the lighting location together with data on a swappable trailer can be advantageous, for example, if the vehicle is a semi-trailer truck with a swappable trailer. Particularly relevant locations on the trailer, such as the upper rear corner, vary depending on the shape and size of the trailer. Accordingly, it can be particularly advantageous for the driver to be able to call up exactly the stored lighting location(s) that were also saved for the respective trailer. In many cases, it is already possible to store trailer data (weight, axle loads, special trailer functions, etc.) in the tractor unit. Lighting locations could therefore be stored together with this data and automatically made available to the driver when the trailer is attached.

[0034] According to a further embodiment, the selection tool for selecting the at least one illumination point comprises at least one of the following elements displayed on the display unit: a crosshair, a magnifying glass, and navigation arrows for shifting the direction of the at least one illumination point. Such elements are often used to select areas or points and therefore represent a particularly intuitive solution for selecting the illumination point.

[0035] Additionally or alternatively, the input unit for controlling the selection tool includes arrow keys, a control lever, e.g., a joystick, and / or a touch-sensitive surface on the display unit. Haptic controls can be operated accurately by the driver, especially during bumpy rides. The use of a touch-sensitive surface offers the possibility of a particularly flexible design of the passenger compartment and, in particular, offers the possibility of creating a particularly appealing and uncluttered design.

[0036] According to a preferred embodiment, the input unit comprises a pivotable and rotatable operating lever, for example, a pivotable and rotatable joystick. Furthermore, it can be provided that the width of a light cone around the illumination point can be changed by rotating the operating lever. The width of the light cone can be increased or decreased, for example, by successively switching adjacent light sources of an LED matrix module on or off. Additionally or alternatively, the selection tool for selecting the illumination point can be operated by pivoting the operating lever, and / or the lighting unit can be activated by pressing a button mounted on the operating lever and / or adjacent thereto. Depending on the design, the pivoting of the operating lever can be achieved by a pivoting movement or a lateral displacement of the operating lever.The button for activating the lighting unit can be mounted either directly on the control lever or adjacent to it, e.g. in close proximity to it, so that the driver can reach the button without having to take his hand off the control lever.

[0037] Such a control lever provides the driver with a particularly simple operating option, as, depending on the model, they can control the selection tool for selecting the lighting position and / or adjust the width of the light cone and / or activate the lighting unit with a single control lever. The haptic control element design allows the driver to operate it accurately even while driving. Once the driver is familiar with the controls, they no longer even need to look at the control element, thus further increasing driving safety.

[0038] According to a further general aspect of the present disclosure, a mirror replacement system for a vehicle is provided, which has a vision system as described herein. The recording unit preferably captures the field of view of a main rearview mirror and / or a side wide-angle mirror. In this case, the field of view preferably covers the statutory fields of view of classes II and / or IV according to the ECE R46 / 04 standard. To record the fields of view, for example, a single camera can be used to cover the entire specified field of view. Alternatively, multiple cameras can be used, each covering partial areas of the field of view. The image data from the individual cameras can then be combined to form combined image data.

[0039] Furthermore, a vehicle, preferably a motor vehicle, is provided, comprising a vision system as described herein. The vehicle is particularly preferably a commercial vehicle, for example a truck, a bus, a construction machine, a tractor-trailer combination or a semi-trailer combination. In a preferred embodiment, a partial region of the vehicle, preferably a lateral outer partial region of the vehicle, comprises a reflective surface layer. This can, for example, be parts of the outer wall of the vehicle if they consist of a reflective material, e.g., a metal or a reflective tarpaulin. Additionally or alternatively, a reflective coating or a reflective film can, for example, be applied to the outer wall of the vehicle in order to form and / or suitably adjust the reflective properties.The lighting unit is designed to illuminate the reflective surface layer in such a way that the reflection of a light cone originating from the lighting unit illuminates at least a portion of the recorded field of view. This indirect illumination of the vehicle's surroundings makes it possible to achieve particularly uniform and extensive illumination. In particular, the illuminable area can be increased if the reflection on the outer wall can illuminate areas of the vehicle's surroundings that cannot be reached by the light cone emanating directly from the lighting unit. To avoid lateral shadows or lateral reflections, the indirect illumination by reflection can preferably be combined with the direct illumination by the light cone of the lighting unit.

[0040] According to a further embodiment, the vehicle comprises a short-range object detection system, preferably an alarm system, which is or can be connected to the lighting unit via a control unit. The short-range object detection system is preferably designed to detect an object in the near vicinity of the vehicle. The short-range object detection system can, for example, be designed like the short-range object detection system described in published patent application DE 10 2015 002 618 A1.

[0041] The control unit is designed to activate the lighting unit when an object is detected by the short-range object detection system. If an approaching object is detected by the short-range object detection system, e.g., during unfavorable lighting conditions, the lighting unit can be activated, allowing a closer view of the detected object. The lighting unit can also be activated in poor lighting conditions to improve object detection by the short-range object detection system. If the detected object is, for example, a person approaching the vehicle without authorization, activating the lighting unit can also have a deterrent effect on the person. Overall, vehicle safety can be improved by combining the short-range object detection system with the vision system.

[0042] The above-described preferred embodiments and features of the invention can be combined with one another as desired. Further details and advantages of the invention are described below with reference to the accompanying drawings. They show:

[0047] Figure 5 is a schematic representation of a display unit according to another embodiment of the present disclosure;

[0048] Figure 6 is a schematic representation of a display unit and an actuating unit according to a further embodiment of the present disclosure; and

[0049] Figure 7 is a schematic representation of a vehicle with a vision system according to a further embodiment of the present disclosure.

[0050] The embodiments shown in the figures correspond at least partially, so that similar or identical parts are provided with the same reference numerals and for their explanation reference is also made to the description of the other embodiments or figures in order to avoid repetition.

[0051] Figure 1 shows a schematic representation of a vision system 1 for a vehicle 2. The vision system 1 comprises a recording unit 9 for recording image data of an external field of vision of the vehicle 2. The recording unit 9 can, for example, comprise one or more cameras, e.g., CCD cameras and / or CMOS cameras, and / or various lenses. The field of vision recorded by the recording unit 9 comprises, for example, the field of vision corresponding to the field of vision of a main rearview mirror and / or a wide-angle mirror. However, it can also alternatively or additionally comprise other fields of vision, for example, the field of vision of a front mirror, a ramp mirror, or a rearview camera. The vision system 1 can be part of a mirror replacement system of the vehicle 2. In the example shown in the figure, the recording unit 9 comprises two cameras or camera lenses, which, for example, overlook a lateral, rearward area of ​​the vehicle's surroundings.The upper camera can cover the field of view of a main rearview mirror, and the lower camera can cover the field of view of a wide-angle mirror. For this purpose, the lower camera can be angled downward.

[0052] Furthermore, the vision system 1 comprises a lighting unit 6 for illuminating at least a portion of the outer field of view. The recording unit 9 and the lighting unit 6 are mounted on a bracket 3, which is attached or can be attached to the outside of the vehicle 2.

[0053] Such a vision system 1 can be advantageous, for example, when unfavorable lighting conditions prevail in the external vehicle environment, for example during darkness or in the case of spatially highly uneven external lighting. In such a case, cameras typically used in vision systems for vehicles are often unable to capture sufficiently high-quality images of the vehicle environment, meaning that the driver is not provided with sufficiently accurate information about the vehicle environment. In a dark vehicle environment, in the worst case, the driver only sees a dark screen. In the case of uneven lighting, individual areas of the vehicle environment may be brightly lit while other areas are dark, e.g. due to lateral shadows. In this case, obstacles in the dark areas can easily be overlooked by the driver.On the other hand, unfavorable reflections in the bright areas can lead to glare effects, which in the worst case can make the captured images completely unusable.

[0054] The vision system 1 shown in the figure therefore offers the possibility of illuminating the field of view surveyed by the recording unit 9. In particular, the field of view can be illuminated from precisely the direction from which the recording unit 9 records the image data. On the one hand, this can increase the amount of light available in a dark environment, so that the recording unit 9 has a sufficient amount of light available to record high-quality image data. In addition, the illumination of the vehicle's surroundings from the direction of the recording unit 9 results in particularly uniform illumination of the vehicle's surroundings from the perspective of the recording unit 9. In particular, lateral shadows and reflections due to lateral light incidence relative to the recording unit 9 can be avoided or at least reduced.Overall, the combination of the lighting unit 6 with the recording unit 9 improves the image quality of the image data recorded by the recording unit 9 in unfavorable external lighting conditions. This makes using the vision system 1 easier and more pleasant for the driver. It also increases driving safety by reducing the risk of the driver overlooking important details in the vehicle's surroundings.

[0055] The lighting unit 6 can preferably be designed to generate or emit different partial light distributions. In this case, the entire field of view surveyed by the recording unit 9 can be illuminated by the lighting unit 6. In addition, partial light distributions can optionally be generated or emitted that do not illuminate partial areas of the surveyed field of view, or only illuminate them with lower light intensity. This can be advantageous, for example, if a highly reflective object in the vehicle's surroundings would lead to overexposure and thus deterioration of the recorded image data if illuminated with maximum light intensity. An example of such a situation could be a reflective traffic sign, which, when illuminated with maximum intensity, would only be recorded as a brightly overexposed area, so that its inscription would no longer be legible or would only be legible with difficulty.Providing a partial light distribution that illuminates the object, e.g., the traffic sign, with low intensity, while simultaneously illuminating other parts of the field of view more brightly, e.g., with maximum intensity, offers the possibility of providing uniformly high-quality image data across the entire field of view.

[0056] On the other hand, it can also be advantageous not to illuminate a larger part of the field of view recorded by the recording unit 9, or to illuminate it only with lower intensity, while one or more partial areas are brightly illuminated. In this way, critical areas, e.g., an obstacle or a parking space, can be specifically illuminated by the lighting unit 6, so that the driver's focus is directed particularly to these critical areas. To generate or emit partial light distributions, the lighting unit 6 can preferably be designed as a matrix module 25. For this purpose, several light sources 31 are arranged in a row and / or column-shaped pattern. The light sources 31 can be, for example, LED and / or laser light sources. Alternatively, matrix-like light deflection elements, e.g., mirrors, can be used, which are controlled by a further light generation unit (not shown), e.g.,by one or more laser diodes, which can redirect the light into the outer field of vision of the vehicle 2.

[0057] The individual light sources 31 are integrated into the holder 3. Each of the light sources 31 can in turn comprise several individual light sources. For example, each of the light sources 31 could consist of a plurality of individual LEDs. The light sources 31 can all have the same shape and / or size, but they can also be designed differently from one another. The distances between the individual light sources 31 can be the same everywhere. Alternatively, an arrangement in a non-uniform pattern is also possible. In particular, the light sources 31 of the matrix module 25 can preferably be arranged on both sides of the recording unit 9, so that the recording unit 9 is surrounded on both sides by elements of the matrix module 25. In the example shown in the figure, the light sources 31 are located on the right and left sides of the recording unit 9.An arrangement in which the light sources 31 are additionally or alternatively located above and below the recording unit 9 is also possible. If the recording unit 9 comprises multiple cameras, the multiple cameras can be arranged adjacent to one another, as shown in the figure. However, it is also possible for one or more light sources 31 to be arranged between the multiple cameras.

[0058] The individual light sources 31 can preferably be activated and deactivated independently of one another. Particularly preferably, the light intensity of the individual light sources 31 can also be adjusted independently of one another. By specifically activating and deactivating the individual light sources 31, partial areas of the outer field of view can be illuminated with maximum intensity, while other partial areas can be excluded. Activation with reduced intensity makes it possible to illuminate partial areas with lower light intensity if, for example, this improves the image quality of the recorded image data. In addition, softer and therefore more pleasing to the eye transitions between illuminated and unilluminated areas can be created. The holder 3 is preferably designed as a boom, e.g. as a lateral boom, which is or can be connected to the outer wall of the vehicle 2.For this purpose, the holder 3 can have a fastening interface at the end region that is attached to the vehicle 2, in order to fasten the holder 3 to the vehicle, e.g., by screwing it. The receiving unit 9 and the lighting unit 6 are preferably designed as separate components that are held to the holder 3 by means of fixing elements. Alternatively, the receiving unit 9 and / or the lighting unit 6 can be integrated into the holder 3 as a common assembly. Such an assembly can be attached particularly easily and flexibly to a variety of different vehicle types and can even be retrofitted to existing vehicles 2.

[0059] Figure 2 shows a schematic block diagram of a vision system 1 for a vehicle 2 according to another exemplary embodiment. To illustrate the individual components and functions of the vision system 1, reference is also made below to Figures 3 to 7.

[0060] In the example shown in Figure 2, the vision system 1 of Figure 1 has been expanded to include a control unit 11, which is or can be connected to the recording unit 9 via a signal connection 26. The control unit 11 can, for example, be implemented on a control unit of the vehicle 2 or be designed as a separate device. In addition, the vision system 1 can preferably comprise a display unit 7, which is also connected to the control unit 11 via a signal connection 26, or can be connected to it. The display unit 7 can, for example, be arranged in the cockpit area of ​​the driver's cab, where it can be easily viewed by the driver. Image data from the field of view of the recording unit 9 is displayed on the display unit 7. For this purpose, the control unit 11 selects which subset of the image data from the recorded field of view is displayed on the display surface(s).In particular, the representation can cover the entire recorded field of view or only a part of it.

[0061] The display unit 7 can comprise one or more display surfaces, for example, displays and / or projectors with associated projection surfaces. The display unit 7 can comprise display surfaces that are used exclusively for the display unit 7 of the vision system 1. Additionally or alternatively, the display unit 7 can further comprise one or more display surfaces that are already present in the equipment of the vehicle 2, for example, one or more display surfaces of an infotainment system and / or a mirror replacement system and / or a rear-view camera system. For example, the display unit 7 can comprise two screens, which are arranged, for example, on the left and right sides in the cockpit area. The screen arranged on the right, as seen from the driver, can display the image data from the right-hand recording unit 9, and the screen arranged to the left of the driver can display the image data from the left-hand recording unit 9.

[0062] Furthermore, the control unit 11 can be designed to display a selection tool on the display unit 7, with which the driver can select a location in the field of vision. A location can designate a point or a limited but extended area. The location can, for example, comprise a location on the vehicle 2 or an object or an area in the vehicle's surroundings. The selected location can, for example, be a lighting location 14 that is to be illuminated. The lighting location can be and / or comprise a focus location 21 and / or a zoom location 22, on which the driver would, for example, particularly like to focus. To select such a location, the driver preferably has access to an input unit 8, which is also connected or can be connected to the control unit 11. With the aid of the input unit 8, the driver can operate the selection tool with which the lighting location 14, e.g.the focus point 21 and / or the zoom point is / are determined.

[0063] The lighting location 14 can be a location that is to be illuminated by the lighting unit 6 when a specific switch-on condition 5 occurs. For this purpose, the control unit 11 can, for example, activate or deactivate the light sources 31 of a matrix module 25 in such a way that a partial light distribution is generated or emitted that illuminates the selected lighting location 14.

[0064] The activation condition can be met, for example, if the control unit 11 detects a activation command via the input unit 8. In this way, the driver can precisely decide for themselves whether they want to activate the lighting unit 6 to illuminate the lighting location 14. This can be decided, for example, based on the driving situation and / or the prevailing lighting conditions and / or according to personal preferences. For example, the driver might want to illuminate a shaded parking space even on a sunny day to prevent overlooking obstacles in the area of ​​the parking space and / or to achieve the most even illumination of the critical area. On the other hand, they can also deactivate the lighting unit 6 during darkness, for example, when driving straight ahead normally, so as not to irritate other road users.Additionally or alternatively, the activation condition 5 can also be fulfilled by specified criteria, so that the lighting unit 6 is automatically activated when the specified criteria are met. For example, the predetermined activation condition can be met if the control unit 11 determines that the current time of day or current ambient lighting conditions indicate poor ambient visibility and the vehicle 2 is performing a maneuvering maneuver. In this case, the lighting unit 6 is switched on if, due to the prevailing conditions, it leads to an improvement in the image data recorded by the recording unit 9. The advantage of this variant is that the driver does not have to worry about activation or deactivation, and driver distraction can therefore be reduced.

[0065] The focus point 21 can be a location that the driver wishes to have displayed on the display unit 7. Typically, the driver selects a location as the focus point 21 that is particularly relevant while driving, for example when performing a maneuvering maneuver. For example, an upper rear corner of the vehicle 2, a vehicle body and / or a trailer, and / or a marker light of the vehicle 2, a vehicle body or a trailer of the vehicle 2, a tire of a rearmost axle of the vehicle 2, and a fastening means of a load of the vehicle 2 can be defined as the focus point 21. In the vicinity of the vehicle 2, for example, an obstacle, a parking space, and a following vehicle in a convoy of vehicles can be particularly relevant and can therefore be defined as the focus point 21.The control unit 11 can then select the subset of the recorded image data that includes the specified focus point 21 and subsequently display this image data on the display unit 7.

[0066] The zoom point 22 can be a point that the driver would like to have displayed enlarged on the display unit 7. To do so, the control unit 11 selects the image data that encompasses the zoom point 22 and displays it enlarged on the display unit 7. Typically, a relatively wide area of ​​the vehicle's surroundings is displayed on the display unit 7 of a mirror replacement system. This provides the driver with a good overview of the vehicle's surroundings, allowing them to plan their driving maneuvers with appropriate foresight and carry them out prudently. However, if the driver needs a precise view of a specific detail of the recorded field of view at short notice, this is difficult with such a wide-area display.The definition of a zoom point 22, on the other hand, makes it possible to flexibly call up a specified point as needed by simply pressing the input unit 8, preferably repeatedly, and to display it enlarged on the display unit 7. In this way, the driver gets a detailed view of the specified zoom point 22.

[0067] The illumination point 14, the focus point 21, and the zoom point 22 can each be identical. This means that an illumination point 14 can be simultaneously defined as the focus point 21 and / or the zoom point 22. However, non-identical points can also be defined as the illumination point 14, the focus point 21, and / or the zoom point 22.

[0068] Furthermore, the vision system 1 can preferably be configured to store lighting locations 14, particularly preferably in a non-volatile memory 18 and / or together with data relating to a removable trailer of the vehicle 2. In this way, the driver can store locations that may also be relevant for performing subsequent maneuvers and easily recall them later, as needed, without having to re-adjust the location. If a non-volatile memory 18 is used as the storage medium, the respective location can be recalled even after the vehicle 2 has been completely shut down or parked and then switched on again.

[0069] Figure 3 shows a schematic example of a vehicle 2 and the fields of view 10 recorded by the recording unit 9. The vehicle 2 can, for example, be a vehicle combination consisting of a tractor unit and a trailer, a truck, a bus, a construction machine, or a semi-trailer. Figure 3 shows an example in which the vehicle 2 is designed as a semi-trailer.

[0070] The vision system 1 can be part of a so-called mirror replacement system of the vehicle 2. The vision system 1 corresponds, for example, to the example shown in Figure 1 or 2. The recording unit 9 and the lighting unit 6 are arranged on an outer wall of the vehicle 2 by means of the bracket 3. The bracket 3 is attached, for example, to a side, front, outer wall of the vehicle 2, for example at or near the location where a conventional exterior rearview mirror would normally be mounted.

[0071] In the case shown, the recorded field of view 10 preferably comprises the fields of view of classes II and IV according to the ECE R46 / 04 standard, which in a conventional mirror system would be covered by the fields of view of a main rear-view mirror and a wide-angle mirror. In the example in Figure 3, the edge of the recorded field of view 10 facing the vehicle 2 runs almost parallel to the wall of the front part of the vehicle (the tractor unit), but slightly towards the vehicle 2, so that even when driving straight ahead, at least part of the vehicle wall lies in the region of the field of view 10. The field of view 10 recorded by the recording unit 9 can preferably cover further areas of the vehicle's surroundings 15 that are at a somewhat greater distance from the vehicle 2. The lighting unit 6 is designed to illuminate at least a partial area 12 of the recorded field of view 12.Preferably, the entire field of view 10 can be illuminated by the lighting unit 6.

[0072] Furthermore, the schematically illustrated vision system 1 preferably comprises a display unit 7 and / or an input unit 8, which are arranged, for example, in the cockpit area of ​​the driver's cab. The display unit 7 and the input unit 8 can be designed as a common assembly, for example in the form of a touch display, or they can be arranged separately from one another in the vehicle 2. Both the input unit 8 and the display unit 7 are preferably arranged in or on the vehicle 2 in such a way that they can be easily reached by the driver.

[0073] In Figure 3, a lighting location 14 has been set, by way of example, to the right, rear edge of the vehicle 2. The control unit 11 can be configured to activate the lighting unit when a predetermined switch-on condition, e.g., actuation of the input unit 8, is met. The lighting unit 6 is configured to generate or emit a partial light distribution 4, such that the light cone 28 emanating from the lighting unit 6 illuminates the lighting location 14. If the position of the lighting location 14 changes relative to the lighting unit 6, the control unit 11 is preferably configured to track the light cone of the lighting unit 6.In other words, the control unit 11 can be designed to change the partial light distribution 4 such that the lighting point 14 continues to be illuminated when the position of the lighting unit 6 changes relative to the position of the lighting point 14.

[0074] Furthermore, in the example of Figure 3, the illumination point 14 was simultaneously defined as the focus point 21. Preferably, the control unit 11 is designed to track the focus point 21 depending on a position of the recording unit 9 relative to the focus point 21. This means that the control unit 11 can select the partial area 12 of the recorded field of view 10 for display on the display unit 7 that includes the focus point 21. If the position of the focus point 21 changes relative to the position of the recording unit 9, for example because the vehicle 2 moves relative to the defined focus point 21, the control unit 11 can change the image data displayed on the display unit 7 such that the defined focus point 21 remains in the display.

[0075] For different driving situations or maneuvering operations, different locations in the field of view 10 can be critical, e.g., an obstacle 16, a parking space, or a vehicle edge within the field of view 10. A particular advantage of the present vision system 1 is that it enables the driver of the vehicle 2 to select any location in the recorded field of view 10 that they wish to keep in view, e.g., in order to be able to safely carry out an upcoming maneuver, as the focus point 21 and / or lighting point 14. The vision system 1 then ensures that the lighting point 14 is illuminated by the lighting unit 6 and that the focus point 14 is tracked on the display unit 7 and does not disappear from the image during the maneuvering operation. Safety, in particular the safety of maneuvering operations under unfavorable external lighting conditions, can be increased as a result.

[0076] To carry out such tracking, the control unit 11 can, for example, access information about the vehicle movement, e.g., the speed, the steering angle, and / or an articulation angle between a front part of the vehicle, in this case the towing vehicle, and a rear part of the vehicle, in this case a trailer or semi-trailer. Such information can, for example, be recorded by sensors, e.g., wheel speed sensors, an ABS sensor, and / or a steering angle sensor, and made available via an on-board computer. During ferry operation, the control unit 11 can, for example, continuously receive data on the input side regarding the movement state of the vehicle 2, such as the current speed, the steering angle, and / or an articulation angle between a front and a rear part of the vehicle.This data can be used to determine the position of the lighting unit 6 and / or the recording unit 9 relative to the position of the specified lighting point 14 and / or focus point 21. For clarification, Figure 3 shows a dashed connecting line between the holder 3 and the lighting point 14 or the focus point 21, as well as an angle α between this connecting line and the front part of the vehicle. If the position of the specified point changes relative to the position of the holder 3, e.g. because the articulation angle between a tractor and a trailer changes while cornering, then the value of the angle α also changes. The control unit 11 can preferably determine this angle α and adjust the light cone 28 and / or the partial area 12 shown on the display unit 7 accordingly. The field of view 10 recorded by the recording unit 9 changes.The area illuminable by the illumination unit 6 is not included, but only the partial area 12 of the field of view 10 that is illuminated by the illumination unit 6 or that is displayed on the display unit 7. In Figure 3, this is illustrated by arrows at the edges of the partial area 12. In an alternative approach, image recognition methods can be used instead of sensor data, with which the control unit 11 recognizes the specified location in the recorded image data. The light cone 28 or the image data displayed on the display unit 7 can then be adjusted based on the detected locations.

[0077] Of course, both tracking approaches can be combined to obtain particularly reliable results. The angle α and the connecting line between the illumination point 21 and the mount 3 were shown in the figure primarily for illustrative purposes. The control unit 11 can determine these two values ​​to perform the tracking, but it is also possible for tracking to occur without explicitly determining these two values.

[0078] Furthermore, the vehicle 2 can preferably include a short-range object detection system 30, e.g., an alarm system. The short-range object detection system 30 is connected or connectable to the control unit 11 and the lighting unit 6 via signaling. If an object is detected by the short-range object detection system 30 in the vicinity of the vehicle 2, the control unit 11 can be configured to activate the lighting unit 6. This can be advantageous for the driver, for example, if it is so dark without the additional lighting that it is difficult for the driver to identify the detected object.

[0079] Figure 4 illustrates, by way of example, the user setting a lighting location 14. For this purpose, the figure shows one embodiment of an input unit 8 and a display unit 7.

[0080] The display unit 7 can be designed, for example, as at least one display screen or at least one display surface 23, which is / are arranged in the cockpit area of ​​the vehicle. In the illustrated embodiment, the display unit 7 comprises a display surface 23, e.g., a mirror monitor, on which a selection tool 13, shown here as a crosshair with arrow elements, is displayed. The driver can move the crosshair using the input unit 8, e.g., by appropriately controlling an operating lever 24. Once the center of the crosshair has been positioned at the desired location, this location can be selected as the illumination location 14, e.g., by actuating a confirmation element (not shown) or, if no such confirmation element is provided, e.g., by pressing the operating lever 24.

[0081] In Figure 4, the left display area 23 illustrates the situation in which no lighting location 14 has yet been defined. The right display area 23 illustrates the situation in which a lighting location 14 has been defined by moving the selection tool 13 to the lighting location 14. The displayed display area 23 preferably comprises two different representations on the same screen.

[0082] Alternatively, however, two separate display surfaces 23 can also be provided, which are assigned to a recording unit 9, on which different partial areas 12 of the recorded field of view 10 can be displayed simultaneously with the same or different magnification levels. For example, in this variant, the left display surface 23 could display the entire recorded field of view 10, including legally prescribed fields of view. A smaller image section, which includes the specified illumination point 14, could be displayed simultaneously on the right display surface 23. In an alternative embodiment, the display unit 7 could consist of a different number of display surfaces 23, and / or the display surfaces 23 could be arranged at different positions in the vehicle. Alternatively, the display surfaces 23 could be displayed on a common monitor.

[0083] For better clarity, the display unit 7 is shown in Figure 4 directly next to the input unit 8, which is a similar size. It is of course possible that the input unit 8 and the display unit 7 are not arranged in close proximity to each other. Furthermore, the display unit 7 and the control unit 8 can have different dimensions. In practice, the display unit 7 will in most cases be larger than the input unit 8.

[0084] The input unit 8 preferably comprises an operating lever 24, e.g., a joystick, an optional actuating element (not shown) for defining a lighting location 14, and another optional element for activating the lighting unit. A separate input unit 8 can be provided for each receiving unit, or it can be switched for which receiving unit a lighting location 14 is defined using the input unit 8. The input unit 8 can, for example, be implemented as a door module, i.e., arranged on the driving side in the door area.

[0085] The operating lever 24 can, for example, be designed as a pivotable and / or rotatable joystick. Rotating the operating lever 24 can, for example, change the width of the light cone emanating from the lighting unit around the lighting point 14. By pivoting the operating lever, the selection tool 13 can be operated to select the lighting point 14. Actuating the control element for defining the lighting point 14 can specify a lighting point 14 selected using the selection tool 13. The operating lever 24 can be designed as a pivoting lever. Optionally, the function of operating the selection tool 13 can be locked by pivoting the operating lever 24 when the lighting unit is activated to prevent accidental displacement of the light cone.

[0086] Furthermore, the operating lever 24 can comprise a control element for activating the lighting unit and another optional control element, preferably a button, for activating full-surface illumination of the field of vision. A button can be actuated quickly, precisely, and intuitively, particularly while driving, so that the driver is not distracted, or only minimally distracted, by operating the vision system. Especially in conjunction with the option of full-surface illumination, the button can therefore be particularly advantageous when the driver wants to quickly obtain an overview of a large area of ​​the vehicle's surroundings.

[0087] An embodiment in which a lighting point 14 is illuminated by a partial light distribution 4 is illustrated in Figure 5. Shown on the left is a display surface 23 of the display unit 7 in a state before the lighting unit 6 is activated. A partial area of ​​the recorded image section can be seen on the left display surface 23. A rear part of the vehicle can be seen schematically in the upper half of the left display surface 23. An obstacle 16 can be seen schematically on the bottom right of the left display surface 23. However, due to unfavorable lighting conditions, e.g. during twilight, the vehicle and the obstacle 16 are difficult to recognize. In order to get a closer view of the rear edge of the vehicle during a shunting maneuver, for example, and thus to be able to better recognize when the vehicle might come too close to the obstacle 16, the selection tool 13 has been moved towards the edge of the vehicle.On the right, a display surface 23 of the display unit 7 is shown in a state in which a lighting location 14 has been defined and a partial light distribution 4 has been activated, illuminating the lighting location 14. As can be seen, the edge of the vehicle and the obstacle 16 are significantly easier to see than when the lighting unit is deactivated. The spot-like design of the partial light distribution 4 draws the driver's attention particularly to the selected lighting location 14.

[0088] An embodiment of the magnification function 19 is illustrated in Figure 6. The left display area 23 shows a situation that essentially corresponds to the situation shown in Figure 5. For example, full-surface illumination was activated to illuminate the field of view.

[0089] Shown on the left is a display area 23 of the display unit 7 in a state before the magnification function 19 is activated. A partial area 12 of the recorded image section 10 is visible on the left display area 23. In order to have a closer view of the obstacle 16 during a maneuver, for example, and thus to be able to better recognize when the vehicle 2 might come too close to the obstacle, the selection tool 13 has been moved to the obstacle 16.

[0090] To activate the magnification function 19, the input unit 8 can, for example, comprise a zoom control element 20, preferably a button. The control unit 11 is designed to activate the magnification function 19, preferably in response to an actuation of the zoom control element 20. Upon activation of the magnification function 19, the area around the zoom point 22 is displayed in an enlarged manner. The display area 23 of the display unit 7, shown on the right in Figure 6, shows this in a state after activation of the magnification function 19. The magnification level can, for example, be set to a predetermined value, selected by the driver, or determined depending on the driving speed of the vehicle. In this way, the driver can monitor the area around the zoom point 22 with greater detail.

[0091] Depending on the embodiment, it is possible for the enlarged image section to permanently return to the image section displayed before activation of the magnification function 19 after a predetermined period of time, e.g., after 10 seconds. Alternatively, the magnification function 19 can remain activated as long as the driver continues to operate the zoom control element 20, and immediately return to the previous display upon termination of the operation. Furthermore, it would also be possible for the enlarged image section to be displayed on a different display area 23, so that the unmagnified image section is displayed on a first area and the enlarged image section is displayed on a second display area 23 simultaneously.

[0092] Figure 7 illustrates an embodiment in which a partial area of ​​the vehicle 2, preferably a lateral outer partial area of ​​the vehicle 2, has a reflective surface layer 29. The reflective surface layer 29 can be parts of the outer wall of the vehicle 2 if they are made of a reflective material, e.g., a metal or a reflective tarpaulin. Alternatively, to improve the reflection properties, a reflective coating, e.g., a film or paint, can be applied to the outer wall of the vehicle 2. The lighting unit 6 can be configured to illuminate the reflective surface layer 29 such that the reflection of the light cone 28 originating from the lighting unit 6 is reflected by the reflective surface layer 29 such that at least a partial area of ​​the recorded field of view is illuminated.

[0093] A further use of the reflective surface layer 29 for illuminating the vehicle surroundings 15 outside the immediate light cone 28 is for vehicles 2 that comprise multiple vehicle parts that can be pivoted relative to one another. In Figure 7, the vehicle 2 is designed, for example, as a tractor unit with a pivoting trailer. If the part of the vehicle 2 to which the lighting unit 6 is attached is bent toward the vehicle part with the reflective surface layer 29, for example when cornering during a maneuver, the light cone 28 shines against the pivoted vehicle part if it runs parallel to the vehicle part of the lighting unit 6.

[0094] The indirect illumination of the vehicle surroundings 15 allows for particularly uniform and extensive illumination of the vehicle surroundings 15. In particular, the area that can be illuminated laterally from the vehicle 2 can be increased, since the reflected light cone can extend further away from the vehicle 2 than the light cone 28 that is maximally generated or emitted by the lighting unit 6. To avoid lateral shadows or unfavorable reflections, the indirect illumination via reflection can optionally be combined with the direct illumination by the light cone 28 of the lighting unit 6. Although the invention has been described with reference to specific exemplary embodiments, it will be apparent to a person skilled in the art that various changes can be made and equivalents can be used as substitutes without departing from the scope of the invention.Consequently, the invention is not intended to be limited to the disclosed embodiments, but is intended to encompass all embodiments falling within the scope of the appended claims. In particular, the invention also claims protection for the subject matter and features of the dependent claims, independent of the referenced claims.
