Description

[0001] The invention relates to a real-time method for ensuring a green position of an ego motor vehicle, a motor vehicle with such a real-time method, a computer program with such a motor vehicle, and a computer program product with such a computer program.

[0002] The aim is for motor vehicles to be operated with low or neutral emissions of greenhouse gases. In this case, it is not important whether the motor vehicle itself actually emits greenhouse gases, but whether the vehicle's energy consumption is at least mathematically reduced or is zero. This is achieved through a so-called green status. This green status is certified by a regulatory authority and must be acquired by the owner of the motor vehicle. For a battery-electric motor vehicle, for example, it must be proven that the energy used to charge its battery was obtained from renewable sources. For a motor vehicle with an internal combustion engine, for example, it must be proven that the same amount of fuel consumed (e.g. as so-called eFuel) was produced from renewable sources, for example synthesized.For example, it is possible for an owner to purchase a subscription for their vehicle to be green-lit up to a maximum energy consumption (e.g., based on a mileage reading and / or consumption estimate and / or charging or refueling monitoring). This subscription is documented by a certificate. Alternatively or additionally, the certificate certifies that the energy supplied during each charging or refueling process comes from a renewable (alternatively referred to as sustainable or climate-neutral) source, i.e., from wind power or solar power, for example, or from a synthetic fuel produced with them.

[0003] There is increasing public pressure on private passenger cars, especially those with combustion engines. Whether these vehicles are climate-neutral or not is not readily apparent from the outside. Vehicle owners also want to drive in a climate-neutral manner, but also to make this easily visible to the public—both to set an example and to avoid insults or even damage.

[0004] Based on this, the present invention is based on the object of at least partially overcoming the disadvantages known from the prior art. The features of the invention are derived from the independent claims, for which advantageous embodiments are presented in the dependent claims. The features of the claims can be combined in any technically reasonable manner, whereby the explanations from the following description as well as features from the figures, which comprise additional embodiments of the invention, can also be consulted for this purpose.

[0005] The invention relates to a real-time method for ensuring a green position of an ego motor vehicle, wherein the ego motor vehicle has at least the following components: - a computing device for storing and processing data; - a communication interface for providing information to an external entity; and - a drive train for propelling the ego vehicle, wherein the computing device contains an identification file and a current energy consumption level of the ego vehicle, as well as information concerning a certificate about a green status of the ego vehicle, wherein the certificate contains a permissible maximum energy consumption, The real-time method comprises the following steps in the order mentioned: a. by means of the computing device, determining the current energy consumption level and comparing it with the maximum energy consumption according to the certificate of green status of the ego motor vehicle; and b. by means of the communication interface, providing information reflecting a status according to the current energy consumption level of the ego vehicle to an external entity.

[0006] Unless explicitly stated otherwise, ordinal numbers used in the preceding and following descriptions serve only to clearly distinguish them and do not reflect the order or ranking of the designated components. An ordinal number greater than one does not necessarily imply that another such component must be present.

[0007] It should be noted that the real-time process is set up in such a way that a green position or the current status of the green position can be easily read by external entities at desired times. For example, a green position status is only positive if the current energy consumption level is lower than the maximum energy consumption certified (with a certificate). In one application, a new certificate is created with each new filling, whereby the (ego) vehicle in question always has a positive status because it is not drivable if the filling is insufficient, i.e., it can only be moved in a climate-neutral manner. In one embodiment, a certificate is created via a subscription and / or upon purchase of the (ego) vehicle, which ensures (for example, via an independent body) that a green position is permanently guaranteed, i.e., the status is always positive.The maximum energy consumption is then, for example, an infinite value or a value corresponding to the expected maximum number of operating hours (e.g., significantly higher). However, this value, or the certificate confirming it, is still held by an external body (such as a trusted regulatory authority) and is (currently) queried for each process. The real-time process can preferably be carried out in a few seconds, preferably in under 5 seconds, and particularly preferably in one second or less. It should be noted that this real-time process is carried out automatically without human intervention and, as stated above, in a time regime that is not feasible with human control of even one of the steps in this sequence of steps. At the same time, a high level of precision, security, and trustworthiness in monitoring the green status can be achieved.

[0008] In one embodiment, the owner is the (current) driver or the current driver acting as their responsible representative. In another embodiment, the owner is not the driver of the ego vehicle, but rather a company, and the ego vehicle belongs to its vehicle fleet, and / or an OEM that voluntarily wishes to maintain a green lane or is legally obligated to maintain a valid green lane within a predefined zone (e.g., under threat of a penalty).

[0009] The computing device is, for example, a separate unit or a plurality thereof and / or is integrated into or connected to an on-board computer of the ego vehicle. It includes at least one processor device (for example, a CPU (central processing unit) or a microprocessor) and a data memory (volatile and / or non-volatile).

[0010] The drive train comprises an (electric or fuel-burning) drive motor, which is connected to at least one drive wheel via a transmission and other components in a torque-transmitting manner, so that the torque of the drive motor can be converted into propulsion of the ego vehicle. Energy from an energy storage device (e.g., a battery and / or a fuel tank) is used to propel the ego vehicle. The current energy consumption depends at least on the kilometers driven, the speed, and the acceleration behavior. In one embodiment, the current energy consumption or the quasi-current (e.g., queried at intervals) energy consumption level is transmitted to an external location. Alternatively or additionally, the current energy consumption level is kept up to date by the ego vehicle, for example, by the computing device, and stored for transmission to the testing center.Please note that the energy consumption level is compiled from historical data, and preferably, the certified maximum energy consumption according to the green status is based exclusively on a historically developed energy consumption level. Alternatively or additionally, the energy consumption level is kept up to date from a defined point in time (e.g., from each refill or recharge) and / or the maximum energy consumption is calculated for each consumption period between two refills. In this case, the refills or recharges are part of the data requested to check the green status.

[0011] The identification file is, for example, a SIM (Subscriber Identification Module) for (legitimate) communication within a mobile network (also called a cellular network) and / or an ID of the ego vehicle, which is permanently embedded therein, such as a (preferably digitally stored) chassis number. Alternatively or additionally, the identification file is a visual representation, such as a license plate, which is preferably also stored digitally (not readily changeable). In one embodiment, an identification file contains a plurality of properties of the ego vehicle, which, redundantly and / or complementarily to one another, sufficiently uniquely define the ego vehicle.

[0012] The current energy consumption level can be recorded via continuous or quasi-continuous monitoring and / or by means of a calculation. In today's infotainment systems, for example, consumption data based on complex estimates is displayed in real time. For some applications, it is sufficient to check the green status based on such estimates. In another embodiment, the current charge level of a (high-voltage) battery or the fill level of a fuel tank is monitored continuously or quasi-continuously, and the (relevant) historical charging or filling events are determined or provided by an external source. The historical charging or filling events are, for example, available via operators from external sources, such as a charging station operator or a petrol station operator and / or a fleet manager (for example a so-called OEM).The certificate is kept in the original equipment (OEM) and cannot be influenced, or at least not easily, by the owner of the vehicle. Relevant, for example, are only those historical events that fall within the period covered by the certificate.

[0013] In one embodiment, the information regarding a certificate's green status is the certificate itself. In a preferred embodiment, the information is a (digital) address (possibly with access authorization such as a temporary key) to an external entity, for example, an OEM, a relevant regulatory authority, and / or certification authority. In one embodiment, the certificate is stored in a decentralized manner in the form of a blockchain or similar security technology.

[0014] The maximum energy consumption is a validity restriction for the certificate depending on the current energy consumption level of the ego vehicle at the time of the request or the affixing of a (possibly permanent) label. In one embodiment, a certificate comprises a fixed maximum energy consumption and becomes invalid once this limit is reached. In one embodiment, the maximum energy consumption is (quasi-)dynamic and depends on the payment status of a subscription and / or a respective (calculated or actual) charging or filling from a source that is accepted as renewable, sustainable, or climate-neutral. In one embodiment, a new certificate is created with each charging or filling, whereby in one embodiment, the current energy consumption level of the ego vehicle is already sufficiently specified by specifying the current certificate.

[0015] The communication interface is configured for actively transmitting and / or passively reading data. For example, the communication interface comprises at least one antenna for communication in a cellular network, a WLAN [Wireless Local Area Network], and / or PAN [Personal Area Network]. For example, the communication interface comprises an image display interface for reading a (changing) image. As explained below, in one embodiment, the communication interface is also a permanently attached marking of the ego vehicle, such as a sticker, a registration sticker (preferably with an expiration date), or a color scheme of the ego vehicle (for example, a special green).Such a permanent version of the Ego-Motor Vehicle marking without an expiration date can only be combined with a certificate issued for the expected service life of the Ego-Motor Vehicle. This must be verified when the marking is applied.

[0016] Comparing the current energy consumption level with the maximum energy consumption, for example, is a subtraction calculation. In a purely exemplary, preferably simplified, embodiment, a maximum energy consumption level is determined exclusively by a maximum mileage range. In this case, the current energy consumption level is also a mileage of the vehicle. If the current mileage is less than the maximum mileage range according to the certificate, the green status is acceptable. Under certain circumstances, a minimum difference of, for example, 50 kilometers less than the maximum mileage range must be maintained so that, with sufficient certainty, the green status remains acceptable during an extended stay in the predefined zone.Alternatively or additionally, the current state of charge or the current filling level is the necessary minimum difference between the current energy consumption level and the maximum energy consumption according to the certificate. For example, compliance with the green status is ensured by appropriately restricting charging or filling options within the predefined zone, which is powered exclusively by renewable sources.

[0017] It should be noted that in one embodiment, compliance is insufficient not only if the maximum energy consumption according to the specified certificate is reached or exceeded, but also if a buffer to be maintained is too small.

[0018] The green status reflects the question of whether the certificate is still valid or even whether one even exists. In one embodiment, the information is explicit, such as a written certificate. In one embodiment, the information includes (alternatively or additionally) a representation that requires prior knowledge or enables verifiability, such as a badge or a seal. In information transmitted digitally, for example wirelessly, such information is reproduced in one embodiment to a person on the receiving communication device via a human-machine interface (for example, a screen and / or a loudspeaker). In one embodiment, reference is made to an NFT (non-fungible token).In one embodiment, an action authorization for a machine, for example, a production line in a production facility, is contained or can be used like a key for authorization with the help of a supervisory authority. The latter is therefore purely machine communication, requiring no human intervention. For example, this occurs in real time (e.g., without preparatory planning) in an autonomous production facility.

[0019] It is further proposed in an advantageous embodiment of the real-time method that in step b. the status is provided exclusively in response to a request from an external entity regarding the status of a green position.

[0020] In one embodiment, for example, solely for the performance of regulatory duties in public spaces or in a workshop, the status of a green light is not permanently displayed, but only released upon a (preferably digital) request. Such a request must preferably contain at least the type of requesting entity and / or the specific person or machine identity. In one embodiment, the requested information is provided only if the identity is approved and otherwise denied. In one embodiment, the information is not displayed if the status is negative in order to protect the owner of the ego vehicle from negative consequences.Preferably, the owner will be informed of a negative status and, particularly preferably, the owner will be given the opportunity to rectify the situation so that the status can be set positively within a reasonable timeframe of a request and provision of the information, for example by acquiring a new certificate or one (e.g., a supplementary certificate) required in the respective region in which the ego vehicle is currently located.

[0021] It is further proposed in an advantageous embodiment of the real-time method that the external entity is: - a worker in a production facility, a maintenance worker in a workshop or a security guard, who is preferably positioned in the vicinity of the ego motor vehicle during a request, preferably in a visual relationship with the ego motor vehicle; - a passerby to the ego vehicle; - a mobile or stationary communication terminal; - a regulatory authority which is preferably out of sight of the current position of the ego vehicle during the request; or - an IoT monitoring entity, which is preferably out of line of sight with respect to the current position of the ego vehicle during the request.

[0022] When performing manual work or monitoring automated production work on a (ego-) motor vehicle, it is advantageous if the worker can easily and quickly obtain information about the status of the vehicle currently being processed via the communication interface, preferably exclusively on request. This is also advantageous for a maintenance employee in a workshop, especially if they have to attach or remove a sticker or seal to the vehicle in question. As already described above, for example, a green light is a (regional) regulation and must be checked by a regulatory officer. This can be verified particularly easily and quickly with a high level of reliability using this real-time method. In one embodiment, it is sufficient for this purpose if the person is detected and, if necessary, recognized in the immediate vicinity of the ego-motor vehicle.

[0023] For example, a pedestrian receives (unsolicited) a message that the (ego-) vehicle within their field of vision has a green light. This information is transmitted, for example, via a portable communications device, such as NFC [Near Field Communication], PAN [Personal Area Network], or WLAN [Wireless Local Area Network]. Alternatively or additionally, a visual display on the ego vehicle itself is triggered when a pedestrian is detected, for example via vehicle sensors such as cameras, radar, ultrasound, or magnetic fields (Doppler effect), or other (e.g., motion) sensors. In the latter embodiment, the presence alone represents a sufficient request to trigger the steps of the real-time process.Alternatively or additionally, this initiates a (digital and / or human-intelligible) communication, in response to which a request can be submitted or triggered by the entity in question.

[0024] A mobile communication device, such as that of a passerby, a law enforcement officer, or a maintenance worker, is provided with information about the status of the ego vehicle upon request or simply by registering their presence. The same applies to a stationary communication device, such as a traffic light capable of V2I (vehicle-to-infrastructure).

[0025] For example, for monitoring the green status of motor vehicles (for example, randomly or quasi-permanently), a regulatory authority is able and authorized to remotely query the current status of the (ego) motor vehicle in question. This is done via a network, for example, the mobile network standardized by the GSMA (Global System for Mobile Communications Association) using a data exchange protocol in accordance with UMTS (Universal Mobile Telecommunications System).

[0026] Likewise, for monitoring the green status of motor vehicles (e.g., randomly or quasi-permanently), a responsible entity, such as an OEM (Original Equipment Manufacturer) or fleet manager (e.g., a rental car operator), is enabled and authorized to remotely query the current status of the respective (ego) vehicle. This entity is an IoT monitoring entity, which can preferably also obtain information about other components of the (ego) vehicle. For example, this is carried out wirelessly or wired at a respective (e.g., proprietary) station, such as a workshop during maintenance work or in a parking garage. Alternatively or additionally, via a network.It should be noted that the responsible or executing body is not necessarily on site, but is, for example, a regional, national or international headquarters.

[0027] It is further proposed in an advantageous embodiment of the real-time method that the communication interface comprises at least one of the following components for providing information about the current status of the green position: - a color-changing device, preferably in the area of ​​the sheet metal components and / or window panes of the ego vehicle aligned with the human visual environment; - a screen, preferably for displaying a computer-readable code, particularly preferably an NFT; - an antenna for a preferably independent transmission in the near field or local field to a mobile or stationary communication terminal; and - a projector for projecting the information in question, preferably in a computer-readable and / or human-readable form. - a sound generator for outputting a sound which reproduces the information in question, preferably in a form understandable to humans.

[0028] In one embodiment, the color-changing device is a painting device, for example a painting robot, preferably in a production facility or in a workshop. In another embodiment, or in addition, a color-changing device is configured for applying (for example, printed, colored and / or glossy) film to a motor vehicle. The coloring is preferably applied (according to human perception) to the body, i.e., to sheet metal components such as the hood, a door, or a roof element, and / or the entire painted exterior. In one embodiment, a sticker is additionally or solely affixed in the area of ​​a license plate, for example, integrated into an already conventionally mandatory (operating registration) sticker, for example, using a different coloring (for example, green instead of white).Alternatively or additionally, the paint is applied to a window pane, either completely covering it or in a position that minimally impedes the driver's view, such as the Green Sticker commonly used in Germany for air pollution control in so-called environmental zones. These measures are applied or affixed to components that are visible during normal design operation of the ego-vehicle, i.e., aligned with the visual environment, such as sheet metal components.

[0029] Here, information about the green status is provided digitally (and preferably also requested digitally). The antenna is configured for standardized communication, such as NFC [Near Field Communication], PAN [Personal Area Network], WLAN [Wireless Local Area Network], or UMTS [Universal Mobile Telecommunications System]. The request is preferably also sent to the computing device via the same antenna (a so-called transceiver).

[0030] For example, a screen is arranged in the area of ​​a window pane of the ego vehicle, such as the well-known digital parking meters. A code, such as a barcode or QR code, is preferably displayed on the screen permanently or upon request. In one embodiment, this displays a computer-readable internet link. In one embodiment, the request is made by approaching the ego vehicle, preferably the screen, with a readable and / or authorizing (computer-readable) terminal device (e.g., a physical token with an NFC antenna).

[0031] Alternatively or in addition to a screen, a projector with the same function is provided. The image is projected onto an external surface in the vicinity of the ego vehicle and / or through or onto a window pane of the ego vehicle.

[0032] Here, an embodiment is proposed that does not rely on a line of sight and can thus draw previously unattracted attention of a passerby to the ego vehicle. The sound emitted by a sound generator (e.g., a loudspeaker or a vibratable sheet metal component) is a noise or a voice output that itself contains the information (possibly assuming specific prior knowledge, e.g., generated by an OEM advertisement) or simply draws attention to a display that makes the information readable, such as a projected image. Alternatively or additionally, this merely motivates the passerby to request the green light, with the presence of a passerby already representing the initial request to trigger the real-time process.Preferably, the sound output is to accompany another reproduction of the information about the status of the green position of the ego vehicle, for example to support the emergence of a positive emotion.

[0033] It is further proposed in an advantageous embodiment of the real-time method that the communication interface of the ego motor vehicle is readable by one or more, or the information on the current status of the green position is provided exclusively to one or more: - Diagnostic tool; - person or communication terminal in the area of ​​a workshop or production facility; and - Manufacturing facility.

[0034] A diagnostic tool is used, for example, in a production facility or in a workshop. This is often a vehicle-specific, manufacturer-specific, or standardized device. A diagnostic tool is intended, for example, for so-called on-board diagnostics. In one embodiment, this is connected to the internet or a proprietary communications network. The diagnostic tool can be connected wirelessly or wired to a communications interface of the (ego) motor vehicle. For example, querying the green status for an operating license or a tax-relevant classification is one item on a checklist on the diagnostic tool for the maintenance employee in a workshop.

[0035] For example, the location is already considered a query, such as whether the ego vehicle is in a workshop or a production facility, whereupon the information regarding the green status is provided. It should be noted that the information is then processed by the relevant communication device in a way that makes it readable for a person, for example, visually via a screen and / or acoustically via a loudspeaker.

[0036] For example, a production facility is recognized or submits a request of its own accord, which classifies it as a production facility by the computer system and authorizes it to read its status. This information is therefore provided when a production facility is present or upon an (active) request from a production facility. It should be noted that the information is then converted by the relevant production facility into an action or an authorization for this action, preferably together with a log, which is stored digitally in the manufacturer's sphere and / or in the (ego) vehicle in a readable format.

[0037] It is further proposed in an advantageous embodiment of the real-time method that the entity is a production plant in a production facility, in which a measure characterizing the green position is enabled with the provision of the information by means of the communication interface, preferably according to an embodiment according to the above description, wherein the measure is preferably at least one of the following: - Color scheme of the ego vehicle; - a removable license plate, preferably on the visible external surface of the ego motor vehicle; - an antenna, preferably for NFC, from which the communication interface is preferably formed during operation of the ego motor vehicle, particularly preferably according to an embodiment according to the above description; and - a specific design element, preferably in the externally visible area of ​​the ego vehicle.

[0038] The identifying measure is designed to be detachable or invalidable in the case of a variable status. However, in the case of a fixed-positive status, it is desirable that a license plate created with this measure be inextricably linked to the (ego) vehicle.

[0039] The color scheme can be, for example, a paint or a sticker that covers part of the body or the entire body. In one embodiment, the color or pattern is a protected trademark, for example, a warranty mark or registered design. In one embodiment, the paint or sticker is designed with a pearlescent or lenticular effect, so that attention is drawn and / or information (e.g., information that is understandable to humans and preferably legible) becomes visible depending on the viewing angle.

[0040] The removable license plate, for example, is an operating license plate. Alternatively or additionally, an adhesive film is provided. This is advantageous, for example, for a long-term subscription (e.g., for a year or longer).

[0041] The transmitting device is a pre-installed communication interface of the ego vehicle, for example, for V2X communication or integrated into a digital and wirelessly readable parking meter. Alternatively or additionally, the transmitting device is a (built-in) communication interface specifically configured to provide information on the green light status.

[0042] For example, the transmitting device only has two states, such as on or off, where one of these means a positive status and the other a negative status. For example, the transmitting device is an NFC transmitter (preferably deactivatable).

[0043] For example, the design element is a spoiler, a wheel (colloquially known as a rim) or a tire casing, which is specially designed and also protected in such a way that only certified green vehicles can be equipped with it with a high degree of reliability.

[0044] In an advantageous embodiment of the real-time method, it is further proposed that the certificate is stored as an NFT based on the information.

[0045] In this embodiment, it is proposed that the certificate (individually assigned to the ego vehicle) or the address reference to the certificate is not, or not exclusively, stored by a certification authority, thus creating increased security and thus trustworthiness through blockchain technology. However, the storage location for the certificate is, for example, the ego vehicle itself or its data storage. In another embodiment, the certificate is stored on an edge device, for example, within the sphere of the OEM, or in the cloud.

[0046] According to a further aspect, a motor vehicle is proposed, comprising a computing device for storing and processing data, a drive train for propelling the motor vehicle and a communication interface for providing information to an external entity, wherein the computing device is configured, with the aid of the communication interface, to carry out the real-time method according to an embodiment as described above.

[0047] The motor vehicle is a self-propelled vehicle driven by a drive train with a (for example, electric) prime mover as the torque source, a (transmission-dependent) transmission, and at least one drive wheel, for example, for use on a road, preferably for transporting people and / or goods. The motor vehicle often has a transport cabin for this purpose. Regarding the computing device and communication interface, reference is made, at least optionally, to the preceding description with respect to the real-time method for providing information on the green light status.

[0048] The vehicle-side processing unit is configured (using the wireless communication interface) to execute the said real-time process completely independently or with the support of an external processing unit (cloud, edge device, located portable communication terminal, network-based location) in real time, so that a status can be output immediately, i.e. acutely, in response to a request (e.g., registration of a passerby).

[0049] According to a further aspect, a computer program is proposed, comprising a computer program code, wherein the computer program code is executable on at least one computer such that the at least one computer is caused to carry out the method according to an embodiment as described above, wherein at least one unit of the computer: - in an on-board computer of a motor vehicle, preferably according to an embodiment as described above, and / or - in a cloud or in an edge device.

[0050] The real-time method described here is computer-implemented according to this embodiment. The computer-implemented method is stored as computer program code, wherein the computer program code, when executed on a computer, for example, comprising a data memory and a processor, causes the computer to execute the method according to an embodiment as described above.

[0051] The computer-implemented method is realized, for example, by a computer program, wherein the computer program comprises computer program code. When executed on a computer, the computer program code causes the computer to execute the method according to an embodiment as described above. Computer program code is synonymous with one or more instructions or commands that cause a computer to perform a series of operations, which represent, for example, an algorithm and / or other processing methods.

[0052] The computer program is preferably partially or completely executable on an on-board computer and / or on a separate control device. The term "computer" is used here synonymously with the devices known from the prior art. A computer therefore comprises one or more general-purpose processors (CPUs) or microprocessors, RISC processors, GPUs, and / or DSPs. The computer has, for example, additional elements such as memory interfaces or communication interfaces. Optionally or additionally, the terms refer to such a device that is capable of executing a provided or integrated program, preferably using a standardized programming language (e.g., C++, JavaScript, or Python), and / or controlling and / or accessing data storage devices and / or other devices such as input interfaces and output interfaces.The term "computer" also refers to a plurality of processors or a plurality of (sub-)computers that are interconnected via physical lines and / or otherwise communicatively connected (e.g., over-the-air) and may share one or more other resources, such as data storage. A (data) storage device is, for example, a hard disk drive (HDD) or a (non-volatile) solid-state memory, such as ROM or flash memory [Flash EEPROM]. Memory often comprises a plurality of individual physical units or is distributed across a plurality of separate devices, so that it is accessed via data communication, such as packet data communication (e.g., as per the Internet Protocol [TCP / IP]).The latter is a decentralized solution, where memory and processors of a large number of separate computers are used instead of a (single) central server or in addition to a central server.

[0053] According to a further aspect, a computer program product is proposed on which a computer program code is stored, wherein the computer program code is executable on at least one computer such that the at least one computer is caused to carry out the method according to an embodiment as described above, wherein at least one unit of the computer: - in an on-board computer of a motor vehicle, preferably according to an embodiment as described above, and / or - in a cloud or in an edge device.

[0054] As a computer program product comprising the computer program code described above, a medium such as RAM, ROM, an SD card, a memory card, a flash memory card, or a disc, or stored and downloadable on a server, for example, is possible. Once the computer program is made readable via a readout unit, for example, a drive and / or an installation, the computer program code contained therein and the method contained therein for segmenting self-moving objects can be executed by a computer or in communication with a plurality of server units, for example, as described above.

[0055] The invention described above is explained in detail below against the relevant technical background with reference to the accompanying drawings, which show preferred embodiments. The invention is in no way limited by the purely schematic drawings, whereby it should be noted that the drawings are not to scale and are not suitable for defining proportions. It is shown in Fig. 1 a parked (ego) motor vehicle in communication with its environment; and Fig. 2 a (ego) motor vehicle in a schematic plan view in a workshop or production facility.

[0056] In Fig. 1 shows a schematic representation of a parked (ego) motor vehicle 1 communicating with its surroundings. The ego motor vehicle 1 comprises a drive train 6, which is connected to at least one drive wheel via a transmission and other components in a torque-transmitting manner, so that a torque of the drive motor can be converted into propulsion of the ego motor vehicle 1. Furthermore, the ego motor vehicle 1 comprises a computing device 2, for example embodied as an on-board computer 33 or comprising a (conventional) on-board computer 33, a sound generator 25, a projector 24 (here, purely optionally, the headlights), and a (first) communication interface 3. The computing device 2 comprises a processor 34 and a data memory 35.Within the computing device 2, an energy consumption level 8 of the ego vehicle 1 is kept up to date and stored for transmission to an entity 5 or to a trusted external location (for example, in the cloud 32 or in a proprietary edge device 31). For example, the external location also stores historical data on the energy consumption level 8 (previous fillings or rechargings) and preferably a plurality of certificates 9, each assigned to an identification file 7. It should be noted that a very large number of possibilities are presented here and, for example, only one or a portion of these possibilities is implemented in an application.

[0057] The projector 24 of the ego motor vehicle 1 is configured to project an image (for example, a computer-readable code 22, here a QR code) onto a surrounding surface. The sound generator 25 of the ego motor vehicle 1 is configured to output an acoustic signal (for example, a pleasant sound). This allows information regarding a certificate 9 about a current green status of the ego motor vehicle 1 to be displayed in a computer-readable and / or human-perceivable form. The code 22 projected onto the road by the projector 24 can be perceived or recorded by an entity 5, here a person 27, or more specifically, a passerby 16 or a law enforcement officer 14 using a mobile communications terminal 17. For example, the mobile communications terminal 17 is a so-called smartphone, by means of which the output code 22 can be read.Alternatively or additionally, a corresponding acoustic signal can be perceived in the near field 15 of the ego motor vehicle 1 by means of the sound generator 25. For example, the projection of the code 22 and / or the acoustic signal is triggered when a law enforcement officer 14 (with a correspondingly configured communication terminal 17) enters the visual environment 20 of the ego motor vehicle 1. The visual environment 20 is monitored, for example, by means of optical or magnetic field-based sensors (not shown here), and entry is interpreted as a request to provide information regarding a certificate 9. In one embodiment, the (QR) code 22 comprises an address and access authorization to a trusted authority in which the certificate 9 is stored or which has trusted knowledge of the certificate 9 or the currently valid maximum energy consumption.The correct certificate 9 can be assigned via the unique identification file 7 of the respective ego vehicle 1, whereby the identification file 7 (optionally cryptographically encrypted) or a suitable (e.g., cryptographic) key is released to the entity 5 for querying the green position status from the external location. In another embodiment, or in combination therewith, the status query and provision are carried out by the ego vehicle 1 itself, and corresponding information (e.g., as sound or image) regarding the green position status is provided to the entity 5.

[0058] The (first) communication interface 3 of the ego motor vehicle 1 is configured for communication with another entity 5 outside the (current) visual environment 20. In this exemplary embodiment, a traffic light is embodied as an IoT monitoring entity 19. Using the respective external communication interfaces (e.g., using 5G [fifth generation]), data exchange between the ego motor vehicle 1 and the IoT monitoring entity 19 can be represented. Another entity 5 in this exemplary embodiment is a regulatory authority 18. The regulatory authority 18, for example, monitors a predetermined area within which motor vehicles 1 are located. For example, the regulatory authority 18 randomly monitors the green light status or authorizes a stay within a regulated area, such as an environmental zone within a city.

[0059] The current energy consumption level 8 of the ego vehicle 1 is queried in step a. of the real-time method for ensuring a green status of an ego vehicle 1. The current energy consumption level 8 is compared with the maximum energy consumption. The current energy consumption level 8 is, for example, a mileage reading of the ego vehicle 1. If the current mileage is less than the maximum mileage range according to the maximum energy consumption of the certificate 9, the green status is OK, i.e., positive. In the subsequent step b., the (positive, but possibly also the negative) status is transmitted to a requesting entity 5 (or one within sight and / or hearing distance), for example, as described above.

[0060] In this exemplary embodiment, additional design elements 30 are arranged on the wheels, which, for example, change their color 29 upon request and the result is positive (i.e., a valid certificate 9 for a green position). For example, the design elements 30 then illuminate in green instead of gray, so that it is clearly visible even within the visual environment 20 that the ego motor vehicle 1 has a valid certificate 9 for a green position.

[0061] In Fig. 2 shows a (ego-) motor vehicle 1 in a schematic plan view in a workshop 13 or production facility 11. The ego-motor vehicle 1 is, without exclusion of the general public, largely identical to the ego-motor vehicle 1 in Fig. 1, and in this respect, reference is made to the description therein, and only the differences or additional or alternative details presented there are discussed here. The ego motor vehicle 1 here comprises, in addition to a computing device 2 and a drive train 6, a screen 21 and an antenna 23. The screen 21 is configured to output a code 22, for example, to indicate a status or an address for a certificate 9 regarding a green position. The antenna 23 is also configured to output information regarding the valid certificate 9 and / or the identification file 7, for example by means of RFID (Radio Frequency Identification) and / or NFC (Near Field Communication).

[0062] The production facility 11 or workshop 13 comprises a plurality of production systems 28 (shown here purely schematically as a single-arm robot), whereby only one is designated pars-pro-toto. In this exemplary embodiment, the identification file 7 of the ego motor vehicle 1 has been transmitted to an edge device 31 via the first communication interface 3, so that the associated certificate 9 and its validity can be determined there based on a current energy consumption level 8. For example, a lifelong certificate 9 was purchased for the ego motor vehicle 1. It should be noted that the term "lifelong" merely refers to the period of the maximum design operating hours (and, if applicable, a safety margin) of the ego motor vehicle 1, or a (truly) lifelong green status is guaranteed based on a one-time payment from a provider.

[0063] Once this information has been received, it is determined, for example, using the diagnostic tool 26 of a maintenance employee 12, that this ego motor vehicle 1 may or must be affixed with a sticker (representative of the valid) certificate 9 with a predetermined expiration date (for example, before an expected actual expiration date in the case of a mileage-dependent period) in the area of ​​a license plate. Afterward, a new check must be performed, and a new sticker must be issued. The green status is, for example, integrated into an already conventionally mandatory (operating registration) sticker.

[0064] In a production facility 11, for example, a specific color scheme 29 is to be applied by a color change device. For example, by means of the antenna 23 of the ego motor vehicle 1 and a corresponding receiver on the production facility 28 or color change device, a release is issued by a positive status of the green position. Here, the color change device is set up to apply (for example, printed, colored and / or glossy) film to the motor vehicle 1. Preferably, the color scheme 29 is applied to a wheel (see Fig. 1) or attached to the body, i.e. to at least one sheet metal component, such as the hood, a door or a roof element.

[0065] In one embodiment, a second communication interface 4 as part of a vehicle-mounted computing device 2, for example, comprising the function of a conventional on-board computer 33, can be used to read the information for a production system 28, thus enabling it to be activated. The (positive) status enables the assembly of a special component or the installation or activation of special software. Such a special component is, for example, an antenna 23 for specific communication, for example, an RFID antenna, or a screen 21 in the windshield, as the first communication interface 3. The special software is, for example, display software for displaying a status of the ego motor vehicle 1 and / or for triggering a check of the current status triggered by the presence of a passerby 16.Alternatively or additionally, a release is authorized by a worker 10, who receives human-readable information about the status or computer-readable information via a communication terminal 17 or diagnostic tool 26. Alternatively or additionally, the worker 10 (or maintenance employee 12) only receives a notification (warning) if the status is negative.

[0066] With the real-time procedure proposed here, a green position can be provided easily and immediately.
