Description

[0001] According to claim 1, the invention relates to a positioning device for a navigation system of a motor vehicle, according to claim 9, to an infrastructure facility with a positioning device, and according to claim 14, to a method for navigating a motor vehicle.

[0002] Today, there is a need to provide a wide range of information to a motor vehicle and / or its user, especially the driver. This is particularly true when the motor vehicle is highly automated, fully automated, or autonomously powered or propelled. In such cases, the driver of such a vehicle is permitted to relinquish control of the vehicle, at least temporarily and / or in certain traffic situations, while the highly automated, fully automated, or autonomous vehicle performs the driving task itself – that is, without any intervention from the human user or driver.

[0003] For example, DE 10 2016 217 977 A1 discloses a method for providing traffic area-related information by means of a machine-readable marking that is applied to the traffic area or adjacent to it. The machine-readable marking is detected by means of sensors, and information for navigation on the traffic area or information on the condition of the traffic area is transmitted in coded form.

[0004] Furthermore, DE 10 2015 010 514 B4 discloses a method for determining map information for a map dataset of a navigation environment, whereby objects (such as walls, columns, doors, signs, etc.) are assigned a three-dimensional position. Semantic information describing the meaning and / or purpose of each object can also be assigned to the respective objects.

[0005] DE 10 2014 002 150 B3 discloses a method for determining the absolute position of a mobile unit.

[0006] Particularly in connection with an automatic parking system, it is necessary that the vehicle's current position relative to its parking environment is known to the vehicle's navigation system. As described earlier, with an automatic parking system, the driver or user may be relieved of driving tasks related to the system, meaning the vehicle's position is not determined by the driver or user. Instead, a highly accurate map of the parking environment exists, which is stored, for example, in the vehicle's navigation system. Furthermore, the parking environment includes at least one positioning device, which contains a machine-readable data carrier or a multitude of machine-readable data carriers.These data carriers each have a unique identifier that can be detected and read by the vehicle's sensors (for example, a camera sensor, laser sensor, lidar sensor, ultrasonic sensor, etc.). Furthermore, the high-precision map contains the position of each marker or data carrier, allowing the vehicle's sensors, which may include at least one processing unit, to recognize the data carriers. This enables the vehicle's own position to be determined relative to its surroundings, particularly through the processing unit. Particularly precise position determination is achieved when the vehicle's sensors detect and / or read more than one data carrier simultaneously.

[0007] The need to equip the parking environment, or more generally the traffic environment of motor vehicles, with positioning devices or numerous data carriers clashes with the need for particularly space-efficient infrastructure design, especially for parking facilities, creating a conflict of objectives. Currently, the data carriers are particularly large and inflexible, mounted on a support structure (plastic, wood, etc.) within the traffic environment of the motor vehicle. Especially after retrofitting existing parking facilities or parking garages, the data carriers, along with their respective support structures, may protrude in a disadvantageous manner into a driving lane and / or a parking space intended for the motor vehicle. Furthermore, the information that can be conveyed via the marker or data carrier is currently limited to the identifier.

[0008] The object of the present invention is to provide a particularly efficient and safe navigation system for a motor vehicle in its traffic environment.

[0009] This problem is solved by a positioning device with the features specified in claim 1, by an infrastructure device with the features specified in claim 9, and by a method comprising the steps specified in claim 14. Features, advantages, and advantageous embodiments of the positioning device according to the invention are to be regarded as features, advantages, and advantageous embodiments of the infrastructure device and the method according to the invention, respectively, and vice versa. Features, advantages, and advantageous embodiments of the infrastructure device according to the invention are to be regarded as features, advantages, and advantageous embodiments of the method according to the invention, and vice versa.

[0010] According to a first aspect, the invention relates to a positioning device, which can also be referred to as a "marker," for a motor vehicle navigation system. The positioning device comprises a machine-readable data carrier, in particular more than one machine-readable data carrier, preferably a plurality of such machine-readable data carriers. Data from the data carrier can be acquired and processed, for example, prepared, by means of a translation device, which can, for example, be arranged in the motor vehicle. Thus, information characterized by the data from the data carrier can be provided by means of the positioning device.

[0011] To enable particularly efficient and safe navigation of the motor vehicle in a traffic environment, the invention provides that the positioning device includes an adjustment mechanism by means of which the data carrier can be adjusted between a starting position and at least one further position that is offset from the starting position. Based on the respective position of the data carrier, the positioning mechanism can provide additional information that goes beyond the information characterized by the data on the data carrier.

[0012] The motor vehicle is preferably designed as a car, in particular a passenger car or truck, as a bus, or as a motorcycle. Furthermore, the motor vehicle may be at least partially electrically powered or propelled, in which case the motor vehicle has at least one electric motor and an electrical energy storage device that can be connected to or is connected to it. By means of the electric motor, the energy provided by the electrical energy storage device is converted into mechanical energy during motor operation. This energy is then applied to at least one wheel of the motor vehicle, thereby electrically propelling or propelling the motor vehicle. Moreover, it may be provided that the motor vehicle is capable of highly automated, fully automated, or autonomous operation or propulsion, at least temporarily and / or in certain traffic situations.This means that the motor vehicle has a steering and / or drive unit by means of which the motor vehicle can be propelled or moved without the intervention of a user or driver. In particular, it is stipulated that the motor vehicle has a navigation system and / or a translation device.

[0013] The translation device enables the capture of machine-readable data carriers. Furthermore, the machine-readable data carrier can be processed using the translation device, for example, further processed, prepared, converted, etc. Thus, data from the machine-readable data carrier that has been captured or read can be converted into another data format, such as text, using the translation device. Accordingly, the information characterized by the data on the data carrier can be made available by the translation device, in particular to the (human) user or driver of the motor vehicle, the steering and / or drive unit of the motor vehicle, etc. For this purpose, the translation device may include an output unit by which the information characterized by the data on the data carrier can be made available to the steering and / or drive unit wirelessly and / or via a wired connection.

[0014] The adjustment device has at least one axis by which the data carrier can be adjusted between its initial position and at least one other position. Specifically, these positions are predetermined—that is, they are predefined positions of the data carrier. They can be discrete positions. Thus, the positions are not purely random positions that the data carrier might assume through unintentional and / or improper adjustment, deformation, modification, etc., of the positioning device or the data carrier. When adjusting the positioning device or the data carrier from its initial position, the data carrier can assume and / or traverse an intermediate position or a multitude of intermediate positions. The intermediate positions can also be discrete. Furthermore, the intermediate positions can also be predetermined or predefined.Moreover, the data carrier can be continuously adjustable between the initial position, which for example constitutes a first setting of the data carrier, and at least one further position, which for example constitutes a second setting of the data carrier, so that there are infinitely many intermediate positions between the initial position and the at least one further position.

[0015] It is specifically intended that the data carrier of the positioning device, which can also be referred to as a "marker," occupies more space in a driving corridor and / or parking space designated for the motor vehicle in its initial position than in at least one other position and / or in the intermediate positions. This means that the data carrier can be arranged more compactly in the motor vehicle's traffic environment in at least one other position and / or in the intermediate positions, or vice versa. The motor vehicle's traffic environment refers to the surroundings in which the motor vehicle can be operated in driving mode and / or in parking mode.

[0016] This ensures particularly efficient and safe navigation of the vehicle in the traffic environment, as the respective machine-readable data carrier is adjustable between the initial position and at least one further position or intermediate positions. This allows the machine-readable data carrier to be advantageously positioned in the traffic environment in a space-saving and space-efficient manner. Furthermore, additional information can be advantageously provided due to the dual functionality of the data carrier or positioning device. For example, the user or driver of the vehicle can see or perceive the respective position of the data carrier or positioning device and extract information or additional information from it. In one case, for instance, it is conceivable that the driver...The vehicle user is shown whether the positioning device is operational. For example, a deactivation state of the positioning device or the data carrier can be indicated by the data carrier being in its initial position, whereas an activation state of the positioning device or the data carrier can be indicated by the data carrier being in at least one other position or in one of the intermediate positions.

[0017] In a further development of the positioning device, it is provided that the additional information is characterized by at least one further position of the data carrier. The additional information provided based on the respective position of the data carrier is therefore not characterized by the data on the data carrier itself, but by the respective position of the data carrier. In order to be able to utilize the additional information, i.e., to use it, for example, for navigating the vehicle and / or to provide it via the translation device, it is provided that the respective position of the data carrier can be detected and processed by the translation device. Thus, by enabling the translation device to detect the position of the data carrier, the system can...The additional information is derived from the corresponding acquisition or detection result of the positioning device; that is, the additional information is characterized by the corresponding position of the data carrier. In other words, at least one further position and / or the respective intermediate position can be linked to the additional information. Furthermore, it is conceivable that at least one further piece of additional information is characterized by the respective intermediate position. This means that the number of additional pieces of information that can be provided by the positioning device or the data carrier corresponds to the number of positions that the data carrier or the positioning device can assume. The advantage here is that a particularly large amount of data or information can be provided by means of the respective data carrier.

[0018] Another advantageous embodiment provides that the adjustment device has a pivoting unit by means of which the data carrier can be pivoted about a pivoting axis. This means that the data carrier can be adjusted between the initial position and at least one further position or intermediate positions by pivoting the data carrier about the pivoting axis.

[0019] In this way, the data carrier or positioning device can be adjusted particularly efficiently between the initial position and at least one further position or intermediate positions, since the swivel unit defines or determines the swivel axis around which the data carrier can be pivoted. Furthermore, the adjustment device, equipped solely with the swivel unit, ensures that accidental, unintentional, or improper adjustment or pivoting of the data carrier around any axis other than the swivel axis is prevented.

[0020] According to a further advantageous embodiment of the positioning device, the adjustment device includes a translation unit by means of which the data carrier can be moved translationally along a translational axis. The data carrier is thus adjustable between the initial position and at least one further position or intermediate positions by being moved translationally along the translational axis. If the adjustment device is equipped solely with the translation unit, adjustment around or along an axis other than the translational axis is effectively prevented, thereby preventing unintentional and / or improper adjustment of the data carrier. The translation unit provides an alternative adjustment option for the data carrier to the swivel unit.The translation unit allows the data carrier to be adjusted between its initial position and at least one other position or intermediate positions with particular efficiency and / or minimal effort, as the data carrier can be moved along the translation axis, i.e., translationally. Incorrect operation, for example through misuse or oversight, using an axis other than the translation axis is prevented by the translation unit, since the translation axis is defined, determined, or fixed by the translation unit.

[0021] It is also conceivable that the data carrier is adjustable between the initial position and at least one further position or intermediate positions by being both pivotable about the pivot axis and translationally movable along the translation axis. Consequently, adjusting the data carrier between the initial position and at least one further position or intermediate positions can involve translational movement along the translation axis and / or pivoting or rotating about the pivot axis. In this case, the positioning device's movement mechanism is equipped with both the pivot unit and the translation unit. This makes the data carrier particularly versatile and flexible in its movement between the initial position and at least one further position or intermediate positions, and therefore adjustable.In other words, the adjustment device equipped with both the swivel unit and the translation unit provides more adjustment options for the data carrier than if the adjustment device were equipped only with the swivel unit or only with the translation unit.

[0022] The pivot unit and the translation unit are designed differently from each other. In particular, the translation unit is not another pivot unit, as is already evident from the type of movement provided by the respective pivot and translation units; the pivot unit provides a rotational capability for the data carrier, while the translation unit provides a translational capability for the data carrier. In a particularly advantageous embodiment, the pivot axis and the translation axis are arranged parallel to each other; even more preferably, the translation axis and the pivot axis coincide. Then the data carrier can be pivoted or rotated about the pivot axis or the translation axis, since the translation axis forms or is defined by the pivot axis. Furthermore, the data carrier can then be moved translationally along the pivot axis, since the pivot axis forms or is defined by the translation axis.defined by this.

[0023] In a further embodiment, it has proven advantageous that the adjusting device is formed by a moving element of an adjustable infrastructure element, which is adjustable between an open position, in which the adjustable infrastructure element allows passage, and a closed position, in which the adjustable infrastructure element blocks or prevents passage. The adjustable infrastructure element is part of an infrastructure system. This means that the infrastructure system includes the adjustable infrastructure element, in particular a plurality of infrastructure elements. The respective adjustable infrastructure element is installed at a specific location within the infrastructure system, in particular permanently installed, with at least a part or portion of the adjustable infrastructure element being movable, for example, pivotable.

[0024] If the adjustable infrastructure element is open wide enough, or adjusted far enough into the open position, for example to allow a pedestrian to pass through, then the adjustable infrastructure element permits the pedestrian to pass through it. Conversely, if the adjustable infrastructure element is closed, especially completely closed, then passage through the adjustable infrastructure element is blocked for the pedestrian. The same applies to a motor vehicle.

[0025] When the adjustable infrastructure element is moved between the closed and open positions, it assumes at least one intermediate position, at least briefly. In other words, the adjustable infrastructure element passes through at least one intermediate position during the adjustment. It is equally conceivable that the adjustable infrastructure element is positioned in the intermediate position and remains there.

[0026] If the adjusting mechanism of the positioning device is formed by the moving element of the adjustable infrastructure element, then a given position of the adjustable infrastructure element can correspond to a given position of the data carrier. For example, it can be provided that the fully closed position of the adjustable infrastructure element and the initial position of the data carrier are assigned to each other. Furthermore, a given intermediate position of the adjustable infrastructure element and a given intermediate position of the data carrier can be assigned to each other. Finally, a fully open position and at least one further position, in particular the final position, of the data carrier can be assigned to each other.

[0027] In particular, it is provided that the data carrier is arranged on the adjustable infrastructure element, specifically on the movable part or portion of the adjustable infrastructure element, via the adjustment device. This allows the data carrier to be moved between its initial position and at least one further position or intermediate positions by means of the movement device when the adjustable infrastructure element is moved. Particularly with regard to a space-efficient design of the positioning device or marker, it is therefore especially advantageous if the data carrier is arranged on the adjustable infrastructure element, since the adjustable infrastructure element and the data carrier then share a single installation space, particularly within the infrastructure device.

[0028] The positioning device can have a support surface on which the data carrier can be arranged or is arranged, wherein the support surface is formed by at least a partial area of ​​a surface of an infrastructure element, in particular the adjustable infrastructure element and / or the traffic environment. Accordingly, the data carrier can be applied to the surface or the partial area of ​​the surface and / or be integrated into the surface or the partial area of ​​the surface. The data carrier can be applied to the surface or the partial area, for example, by separating a material of the surface and a material of the data carrier from each other prior to application and then joining the material of the data carrier and the material of the surface to each other by means of a force-fit, form-fit, and / or material-fit connection.Alternatively or additionally, the data carrier can be integrated into the surface by machining the surface, particularly by generating material chips, to form the data carrier on or within the surface. This ensures a particularly reliable hold of the data carrier in place relative to the surface or infrastructure element. Furthermore, it provides particularly effective protection against vandalism targeting the positioning device and / or the data carrier itself.

[0029] Furthermore, it has proven advantageous if the data carrier can be adjusted by means of the moving device into a detection position in which it is aligned with the translation device. Particularly when the translation device is movable, for example, integrated into the vehicle and thus mobile, there is a need to align the data carrier so that it can be detected and / or read by the translation device with maximum efficiency. This is achieved by the adjustment device, which allows the data carrier to be moved and thus aligned with the translation device with maximum efficiency. For example, the data carrier can be aligned with a driving corridor through which the vehicle, in which the translation device is located, travels.

[0030] In a further embodiment, it is provided that the data carrier can be repeatedly, and in particular continuously, adjusted into the detection position by means of the adjustment device as the translation device moves past the data carrier. This is because, when the translation device, for example by means of a motor vehicle, moves past the data carrier, the repeated or continuous adjustment of the data carrier ensures its alignment with the translation device, thus advantageously allowing the detection device to detect the data carrier for a particularly long time. This is especially advantageous for particularly reliable and safe navigation of the motor vehicle using the positioning device or the respective data carrier.

[0031] According to the first aspect, the invention further relates to an infrastructure element with a positioning device for a motor vehicle navigation system. The positioning device comprises a machine-readable data carrier, wherein data from the data carrier can be captured and processed by means of a translation device, so that information characterized by the data on the data carrier can be provided by means of the positioning device. In order to provide particularly efficient and safe navigation of the motor vehicle in its traffic environment, the positioning device of the infrastructure element comprises an adjustment device by means of which the data carrier can be adjusted between a starting position and at least one further position offset from the starting position, wherein additional information can be provided by means of the positioning device based on the respective position of the data carrier.

[0032] As described above, the motor vehicle can be operated in driving mode. Furthermore, the motor vehicle can be operated in parking mode, which is characterized in particular by the fact that the motor vehicle is stationary with particularly low energy consumption, i.e., it is not moving. Finally, the motor vehicle can be operated in park-driving mode, which is characterized in particular by the fact that the motor vehicle drives or can drive to the parking space, especially in a highly automatic, fully automatic, or autonomous manner – even without an occupant.

[0033] In a particularly advantageous configuration of the infrastructure, it features a road network onto which the data carrier can be aligned using the adjustment device. If the translation device is located in or part of the motor vehicle, particularly simple detection and / or reading of the data carrier by the translation device is ensured, since the data carrier can be aligned onto the road network using the adjustment device. This is because the road network is part of the travel corridor through which the motor vehicle travels, i.e., passing the respective data carrier. The road network can, in particular, be a public road network. Accordingly, the infrastructure can be at least part of the public road network. If the infrastructure is designed as a building, the building itself can incorporate the road network.Preferably, the road network and the public road network are interconnected, allowing motor vehicles to easily travel between the public road network and the road network. As part of the traffic corridor, the road network comprises at least one carriageway with a single surface.

[0034] Furthermore, it has proven advantageous if the infrastructure facility includes a parking area associated with the positioning device, which is linked to the positioning device's data carrier. This means that the infrastructure facility can, in particular, be a parking facility. Alternatively, the infrastructure facility can include the parking facility. The parking facility itself can have at least one parking level. If the parking facility is designed as a multi-story car park, or if the parking facility includes a multi-story car park, the parking facility or car park comprises more than one parking level or more than one parking deck, in particular multiple levels.

[0035] Within the parking facility, a motor vehicle is, in particular, operable or operated in parking mode, provided the vehicle is parked in / on the parking space. Furthermore, a motor vehicle is operable within the parking facility in parking mode, in which the vehicle, especially without occupants, drives to the parking space, for example, from a transfer point within the parking facility or from the public roadway. Accordingly, the parking facility can encompass the transfer point and the parking space, which are connected to each other, particularly via the road network. This means that the motor vehicle can easily drive from the transfer point to the parking space or vice versa, especially via the road network.

[0036] The positioning device is located, at least partially, at the parking space, that is, in its immediate vicinity and / or on a structural element of the infrastructure that at least partially forms the parking space. The data carrier can, for example, be located on the structural element that at least partially forms the parking space and be oriented in relation to the parking space. In this way, a motor vehicle, especially one equipped with the translation device, approaching, parked in, or passing by the parking space, can detect the data carrier particularly easily and efficiently. This makes the parking space especially versatile, particularly with regard to the various sizes and / or models of motor vehicles commonly used today.Furthermore, the translation device, in particular its sensors, can be arranged at a different location in the various vehicle models, so that the data carrier of the positioning device can be particularly advantageously aligned with the corresponding installation location of the translation device, for example depending on the vehicle model arranged in the parking space.

[0037] Furthermore, the infrastructure device with the positioning system can be designed to include parking information. As described above, the positioning system can provide this additional information based on the data carrier positioned accordingly. For example, the data carrier can be in its initial position when the parking space is free. It can also be in at least one other position or in one of the intermediate positions when the parking space is occupied, such as by another vehicle parked there. In this way, the additional information about the parking space can be provided to the vehicle operating in parking mode simply by virtue of the data carrier's position.The parking information is conveyed so that the translation device can recognize whether the parking space is available or occupied when the motor vehicle approaches the parking space, for example in parking mode.

[0038] Typically, parking sensors on the vehicle are used to determine the availability of a parking space. However, this often requires a particularly low driving speed, especially in the immediate vicinity of the parking space, to reliably determine whether the space is available. For example, if a particularly short vehicle is parked in the space, especially if it is a perpendicular parking space, this short vehicle can only be detected by the parking sensors from close proximity. If, however, the parking information is provided via the positioning device or the data carrier based on its position, the data carrier can be detected from a greater distance, particularly with the help of a translation device. This means that the additional information can be provided even from a greater distance.This applies especially if the data carrier is located, for example, directly adjacent to the driving corridor or in a part of the traffic environment that is not occupied and / or obscured by average motor vehicles.

[0039] Another configuration of the infrastructure provides that the data carrier of the positioning device is assigned to the transfer point, where the vehicle can be switched between driving and parking modes. Both driving and parking modes are at least semi-automatic, and in particular highly automatic, fully automatic, or autonomous. For example, it is conceivable that the user drives the vehicle, either as the driver or simply as a passenger, to the transfer point and exits the vehicle there. Following this, or as a result of this, or even before, the vehicle is switched to parking mode. After the occupants have exited the vehicle, it drives at least semi-automatically, and in particular highly automatic, fully automatic, or autonomously from the transfer point, especially via the road network, to and into / onto the parking space and stops there.The vehicle parked in the parking lot will then continue to be operated in parking mode.

[0040] This allows for particularly precise positioning at the transfer point. Furthermore, a particularly safe departure from the transfer point is ensured if the respective data carrier is aligned with the vehicle's translation device located at the transfer point.

[0041] According to the first aspect, the invention further relates to a method for navigating a motor vehicle, comprising the following steps:

[0042] A positioning device is provided with at least one machine-readable data carrier or a plurality of machine-readable data carriers. This means that the positioning device can be at least partially formed or provided by providing the at least one machine-readable data carrier or the plurality of machine-readable data carriers.

[0043] A translation device is used to capture and process data from the data carrier. For this purpose, the translation device may, for example, include a reading unit, so that the capture is primarily carried out using this reading unit. In this context, the translation device can be provided in the vehicle beforehand, for example, by equipping the vehicle with the translation device – particularly during the vehicle's manufacture.

[0044] In a further step, information is then provided by the positioning device. Consequently, the data carrier contains the data, or the data is linked to the data carrier, which characterizes the information, so that the data is captured and further processed by the translation device. The information is then provided, for example, to a receiver, such as a steering and / or drive unit of the motor vehicle, by means of which the motor vehicle can be operated or moved at least semi-automatically. This means that the translation device can have an output unit by means of which the information from the data carrier is provided.

[0045] In order to provide particularly efficient and safe navigation of the motor vehicle in its traffic environment, the method according to the invention provides that the data carrier is adjusted between an initial position and at least one further position, which is adjusted relative to the initial position, by means of an adjustment device.

[0046] Furthermore, the process provides additional information dependent on the current position of the data carrier via the positioning device. Specifically, this additional information is provided by moving the data carrier to the respective position—that is, to the initial position, to at least one further position, or to a position between the initial position and at least one further position. This means that the additional information is not characterized by the data on the data carrier itself, but rather by the corresponding position in which the data carrier is located at the time of its detection by the translation device.

[0047] The invention also includes further developments of the method according to the invention, which have features already described in connection with the further developments of the positioning device and / or the infrastructure device according to the invention. For this reason, the corresponding further developments of the method according to the invention are not described again here.

[0048] The invention also includes combinations of the features of the described embodiments.

[0049] A second aspect of the invention relates to a machine-readable data carrier. Features, advantages, and advantageous embodiments of the second aspect are to be regarded as features, advantages, and advantageous embodiments of the first aspect of the invention, and vice versa.

[0050] According to the second aspect, the invention relates to the machine-readable data carrier - in particular for a positioning device or infrastructure device designed according to the first aspect - wherein data from the data carrier can be captured and processed by means of a translation device, so that information characterized by the data from the data carrier can be provided by means of the translation device, wherein the data carrier has a carrier surface and a data component arranged on it, wherein the data carrier has a fastening device by means of which the data component and the carrier surface are or can be fastened to one another.

[0051] This means that, for the production of the data carrier, the substrate surface and the data component are initially prepared separately, and then subsequently bonded together during the manufacturing process. The bond between the data component and the substrate surface can be designed to be removable, i.e., removable without damage, or designed to be permanent, i.e., removable only by damaging the substrate surface and / or the data component.

[0052] In a further embodiment of the data carrier, the data component and the carrier surface are each made of different materials, with the fastening device comprising a portion of the data component material and a portion of the carrier surface material, which are bonded together, in particular by a metallurgical bond. This ensures a particularly reliable attachment of the data component to the carrier surface, or vice versa, resulting in a particularly durable data carrier. Furthermore, the data carrier, which is attached to the carrier surface in this manner by means of the fastening device, is particularly effectively protected against vandalism and / or accidental damage.

[0053] In this context, it has proven particularly advantageous for the data carrier to be designed as a printed product. The data carrier then comprises a substrate made of printable material and a printing substance, preferably with a color on one surface of the substrate and a color on the surface of the printing substance contrasting strongly with each other. At least a portion of the printing substance and at least a portion of the substrate then form the bonding element, as the two portions are materially bonded together. This makes the data carrier particularly easy and / or inexpensive to manufacture, thus enabling its production to be especially economical, i.e., cost-efficient.

[0054] It has proven advantageous to print the data directly onto the substrate surface. Consequently, the data carrier is then at least partially formed by the substrate surface. This means the printing substance is applied or printed directly onto the substrate surface. Therefore, it is conceivable that the data component was printed directly onto an infrastructure element, particularly its surface, to create the data carrier. In this way, at least a portion of the printing substance and at least a portion of the substrate surface form the mounting structure, as the printing substance and the substrate surface are bonded together.

[0055] The data carrier is particularly easy and / or cost-effective to attach or mount at its destination or mounting point if the data carrier is designed as a printed product that includes an adhesive material attached to the printed substrate. Preferably, the adhesive material is located on an adhesive side of the printed substrate facing away from the printed side. Thus, the data carrier, designed as a printed product, can be attached to the mounting point, for example, to the infrastructure element, by means of the adhesive material. In other words, the data carrier is designed as a sticker.

[0056] It is also conceivable to print on the adhesive side of the printing medium to create the data portion. In this case, the printing medium is intended to be transparent so that – when the data carrier or sticker is used as intended, for example in infrastructure facilities – the printed side and the surface of the carrier face each other and are directly adjacent.

[0057] This method ensures particularly advantageous protection of the data, as the printed carrier protects it from external influences. Furthermore, the data carrier is especially easy and efficient to clean, since the printed carrier keeps the data separate from any cleaning agent.

[0058] The carrier surface can be formed by at least a portion of the surface of an infrastructure element of an infrastructure facility (such as the infrastructure facility described above). Accordingly, the infrastructure element can be, in particular, the adjustable infrastructure element described above, or an infrastructure element different from the adjustable one, especially a non-adjustable one. For example, it is conceivable that the data carrier, designed as a sticker, is adhered to an infrastructure element of the infrastructure facility. This provides a multitude of possible attachment locations for the data carrier, which are unavailable to conventional data carriers, such as those mounted on a rigid plate.

[0059] It can be advantageously provided that the data carrier has a protective element arranged on the carrier surface and on the data area, with the data area being located between the protective element and the carrier surface. As described above, the protective element can, for example, be the printing carrier if the data area is printed on the adhesive side. If, instead, the data area is printed on the print side, so that the data area is not covered by the printing carrier from the environment of the data carrier, the protective element is designed as a separate element from the printing carrier. In this case, the protective element is a coating element, such as a separate film, a protective varnish, etc.

[0060] In this context, it has proven particularly advantageous if the protective element exhibits a lotus effect. This means that an outer surface of the protective element, i.e., a surface facing away from the substrate, is especially liquid-repellent, meaning it is particularly difficult to wet with liquids and / or pastes. This prevents dirt particles from adhering to the protective element and potentially obscuring or covering the data. Furthermore, the lotus effect makes the data carrier, and especially the outer surface of the protective element, particularly easy to clean.

[0061] For particularly efficient data capture and / or reading from the data carrier, it has proven advantageous if the data area and / or the carrier surface has a matte finish. This reduces or eliminates unwanted reflections of light, such as sunlight, which would hinder reliable data capture or reading.

[0062] The invention also includes combinations of the features of the aspects.

[0063] An embodiment of the invention is described below. The following is shown: Fig. 1 a schematic representation of a traffic environment of a motor vehicle equipped with a positioning device; Fig. 2 a schematic representation of the positioning device with a machine-readable data carrier arranged in a starting position; Fig. 3 a schematic representation of the data carrier, which is arranged in a position pivoted relative to the initial position; Fig. 4 a schematic representation of the data carrier, which is arranged in a position translated from its initial position; and Fig. 5 A schematic top view of the traffic environment, which has a large number of parking spaces.

[0064] The embodiment described below is a preferred embodiment of the invention. In this embodiment, the described components each represent individual features of the invention that can be considered independently of one another. Each of these features further develops the invention independently and can therefore be considered part of the invention individually or in a combination other than that shown. Furthermore, the described embodiment can also be supplemented by other features of the invention already described.

[0065] In the figures, functionally identical elements are each provided with the same reference symbols.

[0066] Fig. Figure 1 shows a schematic representation of a traffic environment 2 of a motor vehicle 3 equipped with a positioning device 1. The traffic environment 2 is the area in which the motor vehicle 3 can be operated, or is operated, in driving and / or parking mode. Accordingly, the traffic environment 2 can be, for example, a public traffic area, such as a public road network. Furthermore, the traffic environment 2 can include, or at least partially comprise, a parking facility with a roadway network that differs from the public road network, whereby the roadway network and the public road network are interconnected. This means that it is possible to drive the motor vehicle 3 from the public road network onto the roadway network and vice versa.The parking facility can also be designed as a parking garage that has more than one parking level, in particular a multitude of parking levels.

[0067] In this example, the motor vehicle 3 is represented or configured as a motor vehicle (for example, a passenger car). Furthermore, the motor vehicle 3 has an electric machine and an associated or connectable electrical energy storage device, such as an electric battery. This means that the motor vehicle 3 is electrically powered and thus capable of movement. The motor vehicle 3 is also designed to be highly automated, fully automated, or autonomously operable, moving, and propelled. Thus, the motor vehicle 3 has a steering and / or drive unit 4, which is designed to relieve a user 5, in particular the driver, of the motor vehicle 3 from the current driving task, at least temporarily and / or in certain traffic situations. Consequently, the driver or user 5 of the motor vehicle 3 is able to be relieved of the driving task.to avert a traffic incident, whereby the driving task is then carried out by means of the steering and / or drive unit 4. In addition, it can be provided that the motor vehicle 3 drives completely autonomously without a driver or completely without occupants, with acceleration, braking and steering being carried out by means of the steering and / or drive unit 4.

[0068] The motor vehicle 3 can also have a parking mode in which the motor vehicle 3 is operated in order to, in particular driverless or without occupants, drive to a parking space 6 (see Fig. 5) to drive.

[0069] Fig. Figure 1 shows – not exhaustively – some possibilities of how the positioning device 1 can be arranged in the traffic environment 2. The traffic environment 2 is in Fig. Figure 1 depicts a parking deck 7 comprising a ceiling 8, a floor 9, and at least two wall elements 10, 11. Furthermore, the traffic environment 2, or parking deck 7, has an opening 12 that can be opened and closed as needed by means of a door 13. Parking deck 7 also has another opening 14 that can be opened and closed by means of a gate 15. In addition, parking deck 7 is equipped with a safety device 16, which includes, for example, a guidepost 17.

[0070] The floor 9 of the traffic environment 2 or parking deck 7 has a surface 18 on which the motor vehicle 3 is positioned via its wheels 19. The motor vehicle 3 can be moved by rolling its wheels 19 on the surface 18 of the floor 9.

[0071] In the present example, the traffic environment 2, or parking deck 7, is equipped with a plurality of positioning devices 1. A positioning device 20 is arranged on the wall element 10. The wall elements 10, 11 can directly adjoin each other and, in particular, enclose an angle. Furthermore, the respective wall element 10, 11 can have an arc section, so that the wall elements 10, 11 transition into each other via the arc section. In the schematic representation of the traffic environment 2 according to the Fig. 1. The wall element 10 is perpendicular to a forward direction of travel of the in Fig. The wall element 11 is arranged, for example, parallel to the forward direction of travel of the motor vehicle 3. Both wall elements 10, 11 extend completely between the floor 9 and the ceiling 8. Each wall element 10, 11 may have gaps that extend completely between the floor 9 and the ceiling 8. Consequently, each wall element 10, 11 may include at least one pillar and / or column.

[0072] Alternatively or additionally to the arrangement of the positioning device 20, the traffic environment 2 may have a positioning device 21 which is arranged or attached to the wall element 11. Alternatively or additionally, the positioning device 1 may be arranged on the floor 9, in particular on or at the surface 18 of the floor 9.

[0073] This is shown by the positioning device 22. Alternatively or additionally, in Fig. 1 a positioning device 23 is shown, which is arranged on the ceiling 8, in particular on or at a surface 24 of the ceiling 8.

[0074] The traffic environment 2 and the respective positioning device 1 can be directly attached to one another. Alternatively, the respective positioning device 1 can be attached to or in the traffic environment 2 or to / in the parking deck 7 via a holding device 25, wherein the respective holding device 25 can have a spacer element by which the respective positioning device 1 and a surface of the traffic environment 2, such as surface 24 or surface 18, etc., are spaced apart from each other or kept at a distance from each other. This is shown in Fig. Figure 1 illustrates the positioning devices 1 and 26, which in this case hang freely from the ceiling 8. This means that the positioning devices 21 can be arranged on the wall element 11 by hanging from the ceiling 8 of the parking deck 7. The holding device 25 is not required for the respective positioning device 26 if the respective positioning device 26 and the wall element 11 are directly connected.

[0075] In a further embodiment, it can be provided that a first positioning device 1 is attached to a second positioning device 1, in particular via the holding device 25. Fig. 1. This applies to positioning devices 27, 28. A positioning device 29 is attached to or arranged on the safety device 16, in particular on the guide post 17. Positioning devices 30, 31 are arranged on the door 13, whereby the positioning device 30 may be arranged on a glass portion 32 of the door 13. Positioning devices 33, 34 are arranged on the gate 15.

[0076] Fig. Figure 2 shows, in a schematic representation, position device 1, which has a machine-readable data carrier 35, as representative of position devices 20-23, 25-31 and 33, 34. In the present example, the motor vehicle 3 has a translation device 36 (see Figure 2). Fig. 1) by means of this translation device 36, data stored in the position device 1 on the data carrier 35 can be captured and processed. For this purpose, the translation device 36 includes a capture unit or read unit, which is designed to capture at least the data carrier of the position device 1. A corresponding read or capture result is then provided to a processing unit of the translation device 36, so that the data from the data carrier is processed or further processed by the processing unit. Furthermore, the translation device 36 has an output unit to which a processing result from the processing unit is provided, whereby the information from the data carrier is made available by means of the output unit. The information from the data carrier 35 can, for example, be provided to the user 5 or 1.The information is provided to the driver of the motor vehicle 3 by means of an output unit that includes a display element, such as a screen or display, a signal light, etc. Alternatively or additionally, the output unit may include means that allow the user 5 to be provided, transmitted, or conveyed the information characterized by the data on the data carrier 35 visually, haptically, and / or audibly. Consequently, the output unit may, for example, include a loudspeaker and / or a vibration element.

[0077] Preferably, the information characterized by the data on the data carrier 35, i.e., stored in the positioning device, is used to locate the autonomously operated motor vehicle 3, for example, during autonomous driving mode for parking space searches—that is, during parking driving mode—within the traffic environment 2 or in the parking facility, particularly on parking deck 7. In other words, the positioning device 1 can be used to determine the position of the motor vehicle 3, especially during driving mode. For this purpose, a map can be stored in a navigation device, such as a navigation system, of the motor vehicle 3, in which the respective position of the positioning devices 1 is entered, stored, or saved.The information from the data carrier 35 of the positioning device 1 can, for example, contain a unique identifier, such as a number individually assigned to the respective positioning device 1, which is provided to the navigation system and / or the steering and / or drive unit 4 by means of the translation device 36. This means that the output unit of the translation device 36 delivers the corresponding information from the respective positioning device, for example, the unique identifier, to the navigation system of the vehicle 3. By using the translation device 36 to detect the corresponding positioning device 1 and to read the identifier stored in the data carrier 35, at least a rough positioning or self-position determination of the vehicle 3 in relation to the parking facility or in relation to the traffic environment 2 is achieved.If several position devices 1 are simultaneously detected by means of the translation device 36, a particularly precise positioning or determination of self-position is made possible using the map material stored in the navigation system.

[0078] The positioning device 1 has an adjustment device 37 by means of which the data carrier 35 can be adjusted between the initial position and at least one further position that is offset from the initial position. This allows the positioning device 1 to provide additional information that differs from or goes beyond the information provided, and which is characterized in particular by the at least one further position of the data carrier 35. For this purpose, the translation device 36, in particular its reading or acquisition unit, is designed to detect the respective position of the data carrier 35. In other words, the translation device 36 is designed to determine or ascertain whether the data carrier 35 is in the initial position or in at least one further position, in particular in an intermediate position, at the time of reading or acquisition.

[0079] In the present example, the adjusting device 37 has a swivel unit 38 by means of which the data carrier 35 can be adjusted about a swivel axis 39, in particular rotated or rotatable about the swivel axis 39.

[0080] While in Fig. Figure 2 shows the data carrier 35 in its initial position. Fig. Figure 3 schematically shows the data carrier 35, which is arranged in a position pivoted relative to its initial position, in particular in at least one further position or in one of the intermediate positions. This means that the data carrier 35 is positioned from the position shown in the Fig. The starting position shown in 1 was adjusted or pivoted about the pivot axis 39 by means of the adjusting device 37, in particular by means of the swiveling unit 38.

[0081] Fig. Figure 4 shows a schematic representation of the data carrier 35, which is arranged in a position translationally displaced from the initial position, in particular in at least one further position or in one of the intermediate positions. This is because the adjustment device 37 is provided to have a translation unit 40, which defines a translation axis 41. Consequently, the Fig. 1. Data carrier 35 shown in the initial position is moved from its initial position by moving the data carrier 35 along the translation axis 41 using the translation unit 40.

[0082] In this example, the pivot unit 38 has three pivot axes 39, which are arranged in three-dimensional space according to a three-dimensional Cartesian coordinate system. Similarly, in this example, the translation unit 40 has three translation axes 41, which are arranged in three-dimensional space according to the three-dimensional Cartesian coordinate system. This means that the pivot axis 39 and the translation axes 41 of a respective axis of the three-dimensional Cartesian coordinate system coincide. Therefore, if the positioning device 1—as in this example—is equipped with both the pivot unit 38 and the translation unit 40, this results in six independent movement possibilities for the data carrier 35, and thus six degrees of freedom.

[0083] In Fig. 2, Fig. 3 and Fig. Figure 4 shows the data carrier 35, which has at least part of a two-dimensional optoelectronically readable code, such as a QR code. Alternatively or additionally, the data carrier 35 can have a one-dimensional optoelectronically readable code, such as a barcode. Furthermore, the data carrier 35 may have at least one one-dimensional and at least one two-dimensional code, or at least parts or sections thereof. It is also possible that the data carrier 35 has a digital data storage unit designed to provide the stored data, particularly wirelessly.

[0084] In Fig. Figure 1 shows infrastructure elements 42, which can be configured, for example, as the door 13 and / or the gate 15. Furthermore, the infrastructure element 42 can be configured as a barrier system. Each infrastructure element 42 has a movement mechanism 43 by means of which the adjustable infrastructure element 42 can be moved between an open position and a closed position. In the open position, the adjustable infrastructure element 42 allows passage, whereas in the closed position, the adjustable infrastructure element 42 blocks or prevents passage.

[0085] Since the adjusting device 37 is at least partially formed by the moving element 43, such as a hinge unit of the door 13, a roller unit of the gate 15, and / or a pivot unit of the barrier system, the respective positioning device, which is arranged on the adjustable infrastructure element 42, in particular on an adjustable part of the adjustable infrastructure element 42, is adjustable between the initial position and at least one further position and the intermediate positions. Referring to the present example, the positioning devices 30, 31 and 33, 34, respectively, are adjustable between the initial position and at least one further position and / or the intermediate positions by means of the hinge unit and the roller unit, respectively. This is because the positioning devices 30, 31 are arranged on a door leaf of the door, which forms the adjustable part of the adjustable infrastructure element 42.In the present example, the positioning devices 33, 34 are arranged on a roller curtain of the gate 15 designed as a roller door, the roller curtain forming the adjustable part of the adjustable infrastructure element 42.

[0086] Using door 13 as an example, the respective positioning device 30, 31 is in its initial position when door 13 is fully closed. If door 13 is partially open, the respective positioning device 30, 31 is in one of the intermediate positions. If door 13 is fully open, the respective positioning device 30, 31 is in at least one further position, as this at least one further position can be an end position of the adjusting device 37 or of door 13. The initial position can be another end position of the adjusting device 37 or of door 13, whereby when adjusting the adjusting device 37 or of door 13 from the initial position to the at least one further position, the intermediate positions are traversed.

[0087] By being configured to detect the current position of the position device 1, the translation device 36 detects the momentary opening state of the door 13 based on the detection of the position devices 30, 31. Additional information is linked to the respective opening state of the door 13, so that, based on the respective opening state of the door 13, it can be inferred whether a pedestrian might be entering through the opening 12, in particular onto the roadway. This applies analogously to the gate 15 and the barrier system. The additional information characterizing the opening state of the door 13 and the gate 15 can be provided to the steering and / or drive unit 4 by means of the translation device 36, in particular by means of its output unit.It is conceivable that the steering and / or drive unit 4 of the motor vehicle 3 regulates a momentary operation of the motor vehicle 3, such as parking mode and / or driving mode, in such a way that a pedestrian stepping onto the roadway through the opening 12, 14 is not endangered by the approaching motor vehicle 3. Alternatively or additionally, the steering and / or drive unit 4 can be configured to put the safety systems of the motor vehicle 3 into a heightened state of readiness, in particular to initiate pre-crash measures.

[0088] Furthermore, it can be provided that the translation device 36 detects a current movement process of the adjustable infrastructure element 42, so that as the motor vehicle 3 approaches, it can be detected or recognized whether the predetermined infrastructure element 42 is currently being closed or opened.

[0089] Fig. Figure 5 shows a schematic top view of the traffic environment 2, which includes the numerous parking spaces 6. Using the positioning devices 26, which hang from the ceiling 8 of the parking deck 7, as an example, the following explains how the data carrier 35 can be adjusted into a detection position by means of the adjustment device 37, in which the data carrier 35 is aligned with the translation device 36. This is achieved in particular by means of the swivel unit 38, which, for clarity, is shown in Fig. Unless otherwise shown, the respective data carrier 35 or the respective positioning device 1 can be aligned towards the motor vehicle 3 so that the data carrier 35 can be detected or read particularly efficiently by means of the translation device 36. In particular, it is provided that the data carrier 35 can be adjusted into the detection position multiple times, especially continuously, so that the data carrier 35 or the positioning device 1 and the translation device 36 are or remain constantly aligned with each other while the motor vehicle 3 passes by. The in Fig. Positioning device 1, designated 44, has an unfavorable angle relative to the motor vehicle 3 or the transmission device 36, whereas positioning device 1, designated 45, is adjusted to the detection position, with positioning device 45 having assumed a particularly favorable angle relative to the motor vehicle 3 or the transmission device 36. It is conceivable that, for this purpose, the positioning device 1 has a sensor unit by means of which the transmission device 36 or the motor vehicle 3 can be detected, the sensor unit providing a corresponding sensor result to the adjusting device 37. Then, by means of the adjusting device 37, the corresponding positioning device 1 is adjusted to the detection position based on the sensor result, in particular repeatedly or continuously.

[0090] The traffic environment 2, in particular the parking garage, parking facility, or parking deck 7, can be part of an infrastructure facility. This means that the infrastructure facility can be formed by the traffic environment 2, in particular parking deck 7, such that the infrastructure facility includes the positioning device 1. As already mentioned in connection with Fig. As described in section 5, the respective positioning device 1 or data carrier 35 can be adjusted into the detection position by means of the adjustment device 37. Since the infrastructure facility 2 or traffic environment 2 has a ground 9, the surface 18 of which is part of a road network 46, the respective positioning device 1 or data carrier 35 can be aligned with the road network 46 in the detection position. This is because the motor vehicle 3, which is driven in the traffic environment 2 or in the infrastructure facility 2 as intended, i.e., operated in driving or parking mode, travels on the road network 46.

[0091] In Fig. Figure 5 further shows that the infrastructure facility 2 or the traffic environment 2, in particular the parking deck 7, has parking spaces 6, with each parking space 6 being assigned a respective positioning device 1, in particular its data carrier 35. The following are attached to this: Fig. The positioning devices 26 shown in Figure 5 are suspended from the ceiling 8 in the immediate vicinity of each parking space 6. Specifically, the positioning devices 26 hang from the ceiling 8 at a height that does not protrude into a driving and / or parking corridor, allowing standard-sized motor vehicles 3 to safely drive and / or park beneath them. Since the positioning devices 26 assigned to each parking space 6 can be adjusted between the initial position and at least one other position or intermediate positions by means of the adjusting device 37, a position of the positioning devices 26, designated by 47, indicates that the corresponding parking space 6 is occupied by a motor vehicle 3. For this purpose, the positioning devices 47 can, for example, be adjusted from the initial position to one of the intermediate positions or to at least one other end position.Based on this, the positioning devices 26, designated 48, indicate that the corresponding parking space 6 is free. For this purpose, the positioning devices 48 may be arranged in their initial position.

[0092] The respective assignment of the availability status of the corresponding parking space 6 is merely an example; it may be provided that an occupied parking space 6 is indicated by the corresponding position device 1 by the corresponding position device being in its initial position or in one of the intermediate positions. Similarly, it may be provided that a free or available parking space 6 is indicated by the corresponding position device 1 being in at least one further end position or in one of the intermediate positions. This means that the position device 1 provides additional information about the corresponding parking space 6.

[0093] In Fig. Figure 5 further shows how the motor vehicle 3, equipped with the translation device 36, departs from a transfer point 49, to which at least one of the positioning devices 1 or at least one of the data carriers 35 is assigned. In particular, it is provided that the positioning device 1 assigned to the transfer point 49 can be aligned with the transfer point 49 by means of the adjustment device 37, so that a translation device 36 of a motor vehicle 3 located at the transfer point 49 and the positioning device assigned to the transfer point 49 are aligned with each other in a particularly advantageous manner. This is especially advantageous because the motor vehicle 3 can be switched between driving mode and parking mode, particularly at the transfer point 49, with driving mode and parking mode each being at least semi-automatic, and in particular highly automatic, fully automatic, or autonomous.As mentioned above, the respective positioning device 1 is designed for particularly safe navigation of the motor vehicle 3, especially for driverless navigation. Thus, the ability to align the positioning device 1 assigned to the transfer point 49 ensures that the vehicle can approach and / or depart from the transfer point 49, for example, during autonomous driving operation.

[0094] The data carrier 35 of the positioning device 1 shows, as in Fig. Figure 2 shows a carrier surface 50 on which a data portion 51 of the data carrier 35 is arranged, in particular by means of a fastening device 52. The data portion 51 and the carrier surface 50 are each formed from a different material, i.e., from different materials, wherein the fastening device 52 in particular comprises a portion of the material of the data portion 51 and a portion of the material of the carrier surface 50, which are connected to each other, in particular by a material bond. Accordingly, the data portion 51 can, for example, be applied to the carrier surface 50 by means of a material application process, such as welding, painting, spraying, gluing, etc. A stencil can be used as an aid, in particular when the data portion 51 is painted or sprayed on.

[0095] Furthermore, the data component 51 can be a printed product. A printing medium of the printed product is then formed at least substantially from printable material, such as paper, wood, metal, etc., while a printing substance of the printed product, for example toner, ink, etc., is present. As from Fig. 2, Fig. 3 and Fig. As can be seen in section 4, it is particularly advantageous if a surface area of ​​the printing substrate and a surface color of the printing substance contrast very strongly with each other, thereby ensuring particularly efficient readability of the data carrier 35. In the present case, one color of the printing substrate is white and one color of the printing substance is black, or vice versa.

[0096] The printed product or data element 51 can have an adhesive material arranged on the printing substrate, meaning that the fastening device 52 can be formed by the adhesive material. In this way, the data element 51 is designed as a sticker that is adhered to, or can be adhered to, the substrate surface 50.

[0097] Alternatively, the data component 51, i.e., the printing substance, can be printed directly onto the carrier surface 50. Preferably, the carrier surface is formed by a surface of an infrastructure element, for example, the adjustable infrastructure element 42, the door 13, the gate 15, the wall elements 10, 11, the ceiling 8, the floor 9, etc.

[0098] Furthermore, in the present example, the data carrier 35 has a protective element (not shown) arranged on the data portion 51, which forms a protective layer for the data portion 51 arranged on the carrier surface 50. The protective layer or element provides a lotus effect, so that liquids bead up and roll off the protective layer or element and consequently off the data carrier 35 particularly efficiently.

[0099] It is particularly advantageous if the material of the data element 51 or the material of the carrier surface 50 is especially matte in order to avoid disruptive light reflections, such as stray light, light from other vehicles 3, sunlight, etc. Such light reflections impede the efficient detection and / or reading of the corresponding position device 1 by the translation device 36. In the present example, both the material of the data element 51 and the material of the carrier surface 50 are matte.
