Description

[0001] The invention relates to a real-time method for ensuring a green position of a motor vehicle.

[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 with 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 and / or consumption estimate and / or charging or refueling monitoring). This subscription is documented in a certificate. Alternatively or additionally, the certificate certifies that the energy supplied comes from a renewable (alternatively referred to as sustainable or climate-neutral) source for each charging or refueling process, i.e., from wind power or solar power, for example, or from a synthetic fuel produced with them.

[0003] It is considered possible that in the near future, vehicles with conventional combustion engines or electric vehicles without proven sustainable charging will no longer be allowed into certain zones. For example, so-called environmental zones (especially in cities) could be established, into which only those vehicles with a green light signal may enter, or a higher fee could be charged for vehicles without such a green light signal. However, the question remains as to how this could be technically feasible without disrupting traffic flow and / or requiring expensive personnel deployment.

[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 a motor vehicle, wherein the motor vehicle has at least the following components: - a computing device for storing and processing data; - a communication interface for transmitting data between the computing device and an external transmission interface; and - a drive train for propelling the motor vehicle, wherein the computer device contains an identification file and a current energy consumption level of the motor vehicle, as well as information concerning a certificate about a green status of the motor vehicle, the certificate includes a permissible maximum energy consumption, The real-time method comprises the following steps in the order mentioned: a. by means of the communication interface, in the event of a request from an external transmission interface regarding the status of a green position triggered as a result of the motor vehicle actually entering or planning to enter a predefined zone, transmitting the identification file and the current energy consumption level of the motor vehicle to the transmission interface; b. by means of the communication interface, in the event of a request from an external transmission interface regarding the status of a green position triggered as a result of the current or planned entry of the motor vehicle into a predefined zone, transmit to the external transmission interface the information held by the motor vehicle concerning the certificate concerning the green position of the motor vehicle. and after a comparison of the current energy consumption level with the maximum energy consumption according to the vehicle's certificate carried out by a testing centre: c. by means of the communication interface from the external transmission interface, receiving a notice for an owner of the motor vehicle concerned if the current energy consumption level and the determined maximum energy consumption do not match sufficiently.

[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 method is configured such that the note is created when the motor vehicle enters a predefined zone, preferably when the currently transmitted energy consumption level has not changed or has not changed significantly, for example, by less than 1% of the maximum charge level or the maximum fuel level. The real-time method can preferably be carried out in a few seconds, preferably in less than 5 seconds, particularly preferably in one second or less.Preferably, the real-time method can be carried out in such a way that a delay in the current journey of the motor vehicle is not necessary and the note is created before or shortly after the motor vehicle has entered the predefined zone, wherein the real-time method is only started when the motor vehicle is (exactly) entering this zone, or when the motor vehicle can no longer avoid entering this zone (while observing traffic regulations and / or normal driving behavior). In one embodiment, a planned entry from the currently created trajectory of a navigation system, the aid of which is used by the motor vehicle or a driver of the motor vehicle.In one embodiment, a buffer zone of less than one kilometer, preferably approximately 100 meters, is formed in front of the predefined zone, wherein the motor vehicle traveling at a speed of, for example, 30 km / h [thirty kilometers per hour] or faster (exactly straight) receives a request upon entering the buffer zone and will certainly have received the notice before the end of the buffer zone, so that a negative consequence for the owner of the motor vehicle due to an inadequate green light setting can still be averted by refraining from entering the predefined zone from the buffer zone.

[0008] It should be noted that this real-time process is carried out without human intervention and, as stated above, is automated within a time frame that is impossible to implement with human control of even one of the steps. At the same time, a high level of precision and reliability in monitoring the green light status can be achieved. Furthermore, this real-time process can avoid an unpleasant situation for a vehicle owner, for example, because the notice can avoid fines. It also allows a testing center to protect a predefined zone at a manageable cost, preferably by using existing infrastructure (e.g., an automatic toll station).

[0009] 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 motor vehicle, but rather a company, and the motor vehicle belongs to its vehicle fleet, and / or an OEM, which, for example, is legally obligated to maintain a valid green signal within a predefined zone (for example, under threat of a penalty).

[0010] The computing device is, for example, a separate unit or a plurality thereof and / or integrated into or connected to an on-board computer of a motor vehicle. It comprises at least one processor device (for example, a CPU (central processing unit) or a microprocessor) and a data memory (volatile and / or non-volatile).

[0011] 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 mobile network, a WLAN (Wireless Local Area Network), and / or a PAN (Personal Area Network). For example, the communication interface comprises an image display interface for reading a (variable) image.

[0012] The drive train comprises a (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 motor vehicle. Energy from an energy storage device (e.g., a battery and / or a fuel tank) is used to propel the motor 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 motor vehicle, for example, by the computing device, and stored for transmission to the testing center.

[0013] 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 motor vehicle that is permanently embedded in it, such as a (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 easily changeable). In one embodiment, an identification file contains a plurality of properties of the motor vehicle that are redundant and / or complementary to one another to sufficiently uniquely define the motor vehicle.

[0014] 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 (original equipment manufacturer) and cannot be influenced by the owner of the vehicle, or at least not easily. Relevant, for example, are only those historical events that fall within the period covered by the certificate.

[0015] 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.

[0016] The maximum energy consumption is a validity restriction for the certificate depending on the current energy consumption level of the motor vehicle at the time of the request or upon entry into the relevant predefined zone. 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 motor vehicle is already sufficiently specified by specifying the current certificate.

[0017] The green status reflects the question of whether the certificate is still valid or even whether such a certificate even exists.

[0018] 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.

[0019] It should be noted that compliance is insufficient not only if the maximum energy consumption according to the specified certificate is reached or exceeded, but also if the buffer to be maintained is too small.

[0020] In one embodiment, the notice is presented in a format understandable to the driver of the motor vehicle, for example, readable or audible. The notice may be, for example, a cost for entering the predefined zone, which may depend on the green light status, for example. In one embodiment, the notice may be a notification of a penalty payment if the predefined zone is entered or if it is not immediately exited.

[0021] According to a further aspect, a real-time method for ensuring a green position of a motor vehicle is proposed, wherein the real-time method is carried out by a testing center, wherein the testing center comprises a central unit, a monitoring device and a transmission interface and is set up to test a green status of a plurality of motor vehicles, wherein a certificate with a permissible maximum energy consumption is held for each motor vehicle, and The real-time method comprises the following steps in the order mentioned: i. by means of the monitoring device, monitoring whether a motor vehicle is planned or actually entering a predefined zone and identifying the motor vehicle; ii. by means of the test centre's central office via the transmission interface to check the green status, determine a certified maximum permissible energy consumption assigned to the identified motor vehicle and the current energy consumption level of the identified motor vehicle; iii. by means of the test center's headquarters, comparing the determined current energy consumption level with the permissible maximum energy consumption. (iv) if the current energy consumption level and the determined maximum energy consumption do not correspond sufficiently, the central unit shall transmit a note to the owner of the motor vehicle concerned via the transmission interface.

[0022] The real-time method proposed here represents a method that can be implemented or is to be implemented for the same purpose of monitoring the green light status in a predefined zone and under the same time regime as described above with regard to the real-time method with regard to the motor vehicle. In one embodiment, the real-time method proposed here represents one such as is implemented by a testing center with a motor vehicle capable of (exclusively or also) implementing the real-time method. Reference is made to the preceding description of the steps of the real-time method.

[0023] The inspection center comprises a control center, which preferably includes a computer with at least one processor device and / or a data memory, so that the computing operations of the real-time method can be executed or instructed. The monitoring device is configured to detect motor vehicles at least upon entering the predefined zone. In one embodiment, the monitoring device is a station by means of which a motor vehicle or information about the motor vehicle can be detected optically (e.g., via a camera) or via radio transmission (e.g., via PAN [Personal Area Network] or NFC).In one embodiment, the monitoring device is permanently supplied with information about the geolocation of the motor vehicle (or a plurality of motor vehicles) or is only temporarily supplied with this information by an entity that permanently monitors the geolocation, for example, when the motor vehicle enters or (with sufficient probability) will enter the predefined zone to be monitored. The transmission interface is the communication partner of the inspection center or the control center with a communication interface of a (monitored) motor vehicle and is configured accordingly, for example, as a mobile radio node or transceiver for WLAN and / or PAN.

[0024] It should be noted that, in contrast to the real-time method described above with regard to a motor vehicle, it is not necessarily necessary here for the information relating to a certificate to be held and / or transmitted by the motor vehicle in question. In one embodiment, the certificate is held by an external supervisory authority and / or certification body and is made available to the testing center by means of an identification of the motor vehicle in question. Furthermore, it should be noted that the motor vehicle does not necessarily have to hold an identification file; rather, the motor vehicle can be sufficiently reliably identified by the testing center without one, wherein, if necessary, it is not the motor vehicle but the current driver that is recognized, and the relevant certificate is not attributed to the current motor vehicle but the current driver.The driver is identified, for example, using an external device, such as a smartphone, but preferably transmitted via an on-board communication interface of the vehicle, particularly preferably together with an identification file of the vehicle. This is advantageous, for example, in an application involving a rental car that does not have a corresponding certificate for its green status.

[0025] In one embodiment, the motor vehicle is identified exclusively or additionally by means of (image recognition) its license plate, with a representative of the license plate and thus the identity of the motor vehicle or its owner being stored digitally as an identification file (for example, in a certification body or at the testing center). In an advantageous embodiment, an identification file is stored digitally by the motor vehicle and transmitted to the testing center upon request.

[0026] Geolocation is the current location of a vehicle in question. The location is determined, for example, via satellite navigation (e.g., GPS [Global Positioning System], Galileo, or Beidou) or triangulation in the mobile network, but also hodometry.

[0027] In the application with a rental car, for example, the notice is sent to the rental company, who is then liable for a fine, which in turn can be claimed back from the current driver. Preferably, the notice is sent to a fleet manager or the current owner (i.e., the renter), for example, also to an external device, preferably one through which the driver has been identified or which is stored with their identification and accessible to the inspection center with access authorization.

[0028] According to a further aspect, a real-time method for ensuring a green position of a motor vehicle is proposed, wherein the real-time method is carried out by a system for a plurality of motor vehicles, wherein the system comprises a testing center with a central unit and a transmission interface and is configured to test a green status of a motor vehicle, wherein a certificate with a permissible maximum energy consumption is maintained for the respective motor vehicle, and wherein the respective motor vehicle has at least the following components: - a computing device for storing and processing data; - a communication interface for transmitting data between the computing device and an external transmission interface; and - a drive train for propelling the motor vehicle, wherein an identification file and a current energy consumption level of the motor vehicle are kept in the computing device, The real-time method comprises the following steps in the order mentioned: A. when a motor vehicle is planning or actually entering a predefined zone, transmitting its identification file to the inspection centre's transmission interface via its communication interface; B. by means of the test centre's headquarters via the transmission interface to check the green status, determine a certified permissible maximum energy consumption assigned to the identified motor vehicle and the current energy consumption level of the identified motor vehicle; C. by means of the central testing centre, comparing the determined current energy consumption level with the permissible maximum energy consumption according to the determined certificate on its green status. D. if the current energy consumption level and the determined maximum energy consumption do not match sufficiently, by means of the control centre via the transmission interface to the communication interface of the motor vehicle concerned, transmission of a note to an owner of the motor vehicle concerned.

[0029] The real-time method represents a method that can be implemented or is to be implemented for the same purpose of monitoring the green light status in a predefined zone and under the same time regime as described above with regard to the motor vehicle and / or the inspection center. At least one variant of the method is described here.

[0030] In one embodiment, the motor vehicle transmits its identification file automatically and without an external request as soon as it enters a predefined zone. Alternatively, this is only triggered by a request from the inspection center.

[0031] The testing center receives the maximum energy consumption information for itself or the corresponding certificate. This information is transmitted by the vehicle or obtained by the testing center from another source based on the identification file. The current energy consumption level is also not necessarily information provided by the vehicle itself; in one embodiment, it is monitored by an external body, such as a regulatory authority or a certification body. This is possible, for example, via geolocation data and / or by recording (relevant) charging or filling processes.

[0032] Furthermore, an advantageous embodiment of the aforementioned real-time methods is jointly proposed, wherein the monitored predefined zone is preferably a protected environmental zone.

[0033] Here, it is proposed that the real-time method be a method as described above, carried out by a test center and carried out in exchange with a motor vehicle, which in turn is capable of executing the real-time method as described above. Reference is made to the previous description in this regard.

[0034] In one embodiment, a road sign or message informs the driver that the vehicle is entering an environmental zone or will enter it if the journey continues as planned. It can therefore be assumed that the driver is aware that the associated requirements will not be met due to an inadequate green signal and that a penalty will be payable. Alternatively or additionally, the driver (or owner) is only made aware of the lack of a green signal upon or shortly before entering the environmental zone because the driver himself is not completely aware of his green signal status. For example, the owner has purchased a mileage limit adjusted to the expected lifespan or useful life of the vehicle, but then covered more kilometers or exceeded the maximum energy consumption prematurely due to particularly fuel-intensive driving behavior.

[0035] In an advantageous embodiment of the real-time method, it is further proposed that the geolocation of a motor vehicle is monitored by the testing center and that the green position is monitored on the basis of the current geolocation of the motor vehicle in question.

[0036] In one embodiment, the geolocation of a motor vehicle is continuously monitored by the inspection station. In one embodiment, the geolocation of a motor vehicle is continuously monitored by another location. In one embodiment, the motor vehicle itself initiates monitoring by the inspection station when it enters a predefined region (e.g., a country), wherein the region is larger than the predefined zone in which a valid green status is mandatory or at least advantageous. In one embodiment, the geolocation is requested from a motor vehicle using random samples, under the assumption that the green status is generally valid.

[0037] Based on the geolocation, it is then detected whether the vehicle is entering, will enter or has already entered a predefined zone, and the next steps of the real-time process are then triggered.

[0038] In an advantageous embodiment of the real-time method, it is further proposed that the certificate concerning the green status and / or the current energy consumption level is held by an external certification authority.

[0039] For security against fraud, but also for security against data unreliability (e.g., due to different calculation methods), it is advantageous if the certificate and / or the current energy consumption level are stored externally and thus, according to this embodiment, are also the data used as (preferably the only) reliable data in the real-time process. In one embodiment, the certification authority is also the authority that handles issuing certificates. In another embodiment, the certification authority is set up solely for this (and possibly further) process to provide the requested certificate and / or the current energy consumption level. The certification authority is maintained, for example, by a vehicle manufacturer and / or fleet manager.To track the current energy consumption level, the certification body maintains (quasi-)continuous communication with the vehicle in question. In one embodiment, the current energy consumption level is composed of a (previous) energy consumption level stored at the certification body (or alternatively, the testing center) and the current energy consumption (level) of the vehicle (based on the previous data).

[0040] In an advantageous embodiment of the real-time method, it is further proposed that the certificate is held as an NFT.

[0041] An NFT (non-fungible token) is a cryptographically unique, indivisible, irreplaceable, and verifiable token that represents a specific object in a blockchain and is a highly reliable, trustworthy, and globally standardized address pointer to a certificate held by a certification authority. An NFT also offers the advantage of limiting itself to a manageable amount of data as an address pointer, which may not be possible with a certificate. In one embodiment, it is sufficient for a verification authority to present an NFT, and it trusts the existence of the certificate referenced by the NFT if the information on maximum energy consumption is known from another source, for example, provided where the current energy consumption level or part of it (i.e., a previous energy consumption level) is also provided.In one embodiment, the NFT is displayed as a QR code in the windshield of the relevant motor vehicle.

[0042] It is further proposed in an advantageous embodiment of the real-time method that, starting from the motor vehicle, a transmission of at least its identification file is carried out by means of at least one of the following standardized methods: - mobile communications; - Wi-Fi; - PAN; - NFC; and - Image recognition, preferably using a QR code.

[0043] For example, there are inspection stations that, like speed cameras and / or toll booths, are already equipped to uniquely identify a motor vehicle and, if applicable, the current driver. Using artificial intelligence (AI), for example, such identification can be carried out quickly and reliably, and on this basis, a stored identification file can then be uniquely assigned, which in turn allows a certificate and energy consumption reading to be retrieved (for example, by a body external to the vehicle in question).

[0044] It is further proposed in an advantageous embodiment of the real-time method that the note to an owner of a motor vehicle in question includes at least one of the following information: - an indication of costs; - a notice of violation; - a maximum range of kilometers; - a request to improve the green position; and - a stop signal to an engine control unit of the motor vehicle in question.

[0045] In one embodiment, the motor vehicle has no or insufficient green light. In this case, a cost indication is included in the note, preferably such that the current driver can still forgo entering the predefined zone, i.e., avoid the costs, or (in the case of, for example, a time-dependent and / or kilometer-dependent cost indication) can at least keep the costs as low as possible (through restrained vehicle use). With a cost indication, for example, a green light position or the maximum energy consumption can also be changed, preferably by an amount exceeding the expected current energy consumption within the predefined zone. In one embodiment, a cost indication is calculated upon exiting the predefined zone, for example, based on the difference between the energy consumption level upon entering and now upon exiting the predefined zone.Alternatively or additionally, independently if the maximum energy consumption according to the certificate is exceeded at the time of discharge.

[0046] This includes a report for an administrative offense or even a criminal offense. If necessary, the violation report will be accompanied by a cost statement (possibly including a permit to enter or continue driving within the predefined zone). The same applies to exiting the predefined zone.

[0047] For example, it is stated here that a difference between the current energy consumption level and the maximum energy consumption according to the certificate (at least according to the interpretation of the testing center) allows a maximum mileage range within the predefined zone. For example, this is issued as a note in conjunction with exit control and / or monitoring in the predefined zone and a corresponding (increased) cost statement and / or violation notification.

[0048] For example, in this case, a maximum energy consumption cannot be adjusted directly through the inspection body or a new green certificate can be obtained (as indicated above with regard to the cost information). Instead, the owner must arrange a new maximum energy consumption himself (through other channels). For example, entering the predefined zone is subject to a penalty (see above for the violation report and cost information).

[0049] In this embodiment, preferably with a semi-autonomous or fully autonomous motor vehicle, the notice (preferably via a control device of the motor vehicle) effectively prevents the motor vehicle from continuing its journey. The motor vehicle is thus immobilized until a valid green signal is present and cannot enter the predefined zone.

[0050] It is further proposed in an advantageous embodiment of the real-time method that the motor vehicle in question receives a release if the current energy consumption level and the determined maximum energy consumption sufficiently match, wherein preferably an upcoming energy consumption is determined and / or estimated with the release, and / or Preferably, the energy consumption of the motor vehicle in question is monitored until the predefined zone is left again by the motor vehicle in question.

[0051] Here, it is proposed that not only a notice, such as a rejection and / or a cost statement, be issued if the green signal is insufficient, but also a permit to enter the predefined zone. In one embodiment, a motor vehicle cannot enter the predefined zone (without a violation or even by being stopped) unless a permit is issued; thus, entry into the predefined zone is only possible with such a permit from the inspection station (at least without penalty).

[0052] One embodiment also takes into account that energy consumption continues to increase after the motor vehicle enters the predefined zone. For example, due to a marginal difference between the current energy consumption level and its maximum energy consumption, the motor vehicle receives a target value specifying how much energy may still be consumed or how many kilometers may still be traveled while in the predefined zone. If this target is exceeded (for example, regardless of whether the maximum energy consumption has also been exceeded and / or because a green signal is insufficient in itself), an increased cost demand and / or a criminal complaint will be filed.

[0053] In one embodiment, the energy consumption is permanently monitored (e.g. continuously or randomly) as long as the motor vehicle is in the predefined zone and, for example, a note is triggered when the maximum energy consumption according to the certificate (or expiration of such a certificate) is reached or exceeded.

[0054] 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 system for a real-time method for a motor vehicle; Fig. 2 a real-time method for ensuring a green light position of a motor vehicle; Fig. 3 a real-time procedure for ensuring a green light status of a motor vehicle from a test centre; Fig. 4 a real-time method for ensuring a green position of a motor vehicle from a system; and Fig. 5 a predefined zone with three motor vehicles.

[0055] In Fig. 1 shows a system 14 for a real-time method, representative here of a single motor vehicle 1 for a plurality of motor vehicles, in a schematic view. The motor vehicle 1 comprises a computing device 2 for storing data 3, a communication interface 4 for transmitting data 3 between the computing device 2 and a transmission interface 5 of the system 14. Furthermore, the motor vehicle 1 comprises a drive train 6, which is configured to propel the motor vehicle 1. Furthermore, the data 3 of the computing device 2 comprises an identification file 7, an energy consumption level 8, and a certificate 9 for the green position with a permissible maximum energy consumption.In this exemplary embodiment, a QR code 17 is arranged (purely optionally) on the windshield of the motor vehicle 1, wherein the QR code 17 is configured to transmit the identification file 7 by means of image recognition by the inspection center 11 (not shown here).

[0056] The data 3 of the motor vehicle 1 can be transmitted to the testing center 11 via a communications network 20 (for example, via satellite, mobile radio, or WLAN). The testing center 11 comprises a transmission interface 5 for receiving the data 3 of the motor vehicle 1, a monitoring device 13 with a control center 12, a computing unit 18, and a data storage device 19. In one embodiment, the current geolocation 15 of the motor vehicle 1 can be recorded by the testing center 11 via the communications network 20 or a separate geolocation system.

[0057] The testing center 11 is also connected to a certification center 16 via the communications network 20. The certification center 16 also comprises a transmission interface 5, a computing unit 18, and a data storage device 19. The information about the certificate 9 of the motor vehicle 1 is stored, for example, via a (digital) address (possibly with access authorization such as a temporary key) to an external entity, for example an OEM, a corresponding supervisory authority, and / or certification center 16, and can be retrieved by the testing center 11.

[0058] In Fig. 2 shows a real-time method for ensuring a green position of a motor vehicle 1 in a flowchart. The following description refers to the description for Fig. 1, and in this respect, reference is made to the description therein. It should be noted that the real-time process is configured such that a note is created upon entry of motor vehicle 1 into a predefined zone 10, so that the currently transmitted energy consumption level 8 has not changed or has not changed significantly. For example, motor vehicle 1 receives a request upon entering a buffer zone and will certainly have received the note before the end of the buffer zone, so that a negative consequence for the owner of motor vehicle 1 due to an inadequate green signal can still be averted by refraining from entering the predefined zone 10 from the buffer zone. It should be noted that this real-time process is carried out automatically without human intervention and within a time regime which, in this sequence of steps, is not feasible with human control of even one of the steps.

[0059] In step a., upon a request from an external transmission interface 5 regarding the status of a green position triggered as a result of a current or planned entry of the motor vehicle 1 into a predefined zone 10, the communication interface 4 transmits the identification file 7 and the current energy consumption of the motor vehicle 1 to the transmission interface 5. The status of a green position reflects the question of whether the certificate 9 is currently still valid or even whether such a certificate even exists.

[0060] In step b., a request from an external transmission interface 5 regarding the status of a green position, triggered as a result of the current or planned entry of the motor vehicle 1 into a predefined zone 10, is transmitted to the external transmission interface 5 via the communication interface 4, and the information held by the motor vehicle 1 regarding the green position certificate 9 of the motor vehicle 1 is transmitted. A test center 11 then compares the current energy consumption level 8 with the maximum energy consumption according to the certificate 9 of the motor vehicle 1.

[0061] For example, comparing the current energy consumption level 8 with the maximum energy consumption is a subtraction calculation. In a purely exemplary embodiment, a maximum energy consumption is determined exclusively by a maximum mileage range. In this case, the current energy consumption level 8 is also a mileage reading of motor vehicle 1. If the current mileage is less than the maximum mileage range according to certificate 9, the green status is acceptable.

[0062] For example, certificate 9 is held by an external certification authority 16, providing high security against fraud, but also against unreliability of data 3 (e.g., due to different calculation methods). In this exemplary embodiment, certification authority 16 is also the authority responsible for issuing certificates 9.

[0063] Certificate 9, for example, is stored as an NFT (non-fungible token). In addition to its high level of trustworthiness, an NFT also offers the advantage of limiting itself to a manageable amount of data as an address pointer, which may not be the case with a certificate 9. In one embodiment, it is sufficient for a testing center 11 if an NFT is presented (for example, on a windshield of motor vehicle 1) and the existence of certificate 9, to which the NFT refers, is trusted if the information on maximum energy consumption is known elsewhere, for example, provided where the current energy consumption level 8 or a portion thereof (i.e., a previous energy consumption level 8) is also provided.

[0064] In step c., a note for an owner of the motor vehicle 1 in question is transmitted from the external transmission interface 5 via the communication interface 4 if the current energy consumption level 8 and the determined maximum energy consumption do not match sufficiently. In this exemplary embodiment, the note is prepared in a manner that is understandable for a driver of the motor vehicle 1, for example, readable or audible. The note is, for example, a cost indication for entering the predefined zone 10, which depends, for example, on the status of the green light. In an alternative exemplary embodiment, the note is a notification of a penalty payment if the predefined zone 10 is entered or not left immediately. The owner is not necessarily the direct addressee, but the content of the note is directed at his area of ​​responsibility.For example, the note is displayed exclusively on the screen in the cockpit of motor vehicle 1, but motor vehicle 1 is operated as a rental vehicle with a lessee as the driver. However, the lessee of motor vehicle 1 may not be in the position or responsibility to ensure a valid green status. It should be noted that in a leasing agreement, the lessee is usually not the owner. For example, a green status is part of a leasing agreement and is the responsibility of the lessor.

[0065] For example, the note may include additional information: - a maximum range of kilometers; - a request to improve the green position; and - a stop signal to an engine control unit of the motor vehicle in question 1.

[0066] For example, a maximum mileage range indicates that a difference between the current energy consumption level 8 and the maximum energy consumption according to certificate 9 (at least according to the interpretation of the test center 11) allows a maximum mileage range within the predefined zone 10. For example, this is issued as a note in conjunction with an exit control and / or monitoring in the predefined zone 10 and a corresponding (increased) cost indication and / or violation notification.

[0067] If a request is made to improve the green status, for example, a maximum energy consumption cannot be adjusted directly through the inspection body 11 or a new green status certificate 9 can be obtained (as indicated above with regard to the cost information). Instead, the owner must arrange a new maximum energy consumption himself (through other channels). For example, entering the predefined zone 10 is subject to a penalty (see above for the violation report and cost information).

[0068] In the case of a stop signal as a note, in this exemplary embodiment a stop signal is output by means of a control device of the motor vehicle 1, so that further travel, for example in the case of a partially autonomous or fully autonomous motor vehicle 1, is prevented as long as there is no valid green position, and thus the motor vehicle 1 cannot enter the predefined zone 10.

[0069] In Fig. 3 shows a real-time method for ensuring a green position of a motor vehicle 1 by a test center 11 in a flow chart. The following description refers to the description for Fig. 1, and in this respect, reference is made to the description therein. It should be noted that the real-time method is carried out by the testing center 11, which comprises a control center 12, a monitoring device 13, and a transmission interface 5. The testing center 11 is configured to check the green status of a plurality of motor vehicles 1, wherein a certificate 9 with a permissible maximum energy consumption is maintained or at least expected for the respective motor vehicle 1.

[0070] In step i., the monitoring device 13 monitors whether a motor vehicle 1 is planned or currently entering a predefined zone 10 and identifies this motor vehicle 1. For example, the predefined monitored zone 10 is a protected environmental zone within a city or a national park.

[0071] In step ii., the control center 12 of the test center 11 uses the transmission interface 5 to check the green status to determine whether a certified permissible maximum energy consumption assigned to the identified motor vehicle 1 and the current energy consumption level 8 of the identified motor vehicle 1 are present. Using the certified permissible maximum energy consumption, for example, a still available route with the certified fuel supply and / or energy supply of a traction battery is assigned to the motor vehicle 1 based on the current energy consumption level 8.

[0072] The assignment or recording of the current energy consumption level 8 from the motor vehicle 1 to the testing station 11 takes place, for example, via mobile communications, WLAN, or PAN. With these communication standards, data is transmitted within a predefined distance, for example, when the motor vehicle 1 drives through a corridor equipped with corresponding transceivers. In an alternative embodiment, the assignment takes place using an NFC chip, which is read by a suitable reading device, for example at a toll station with a barrier or a slow-speed section. Alternatively or additionally, image recognition is proposed for assignment. For example, an assignment can be displayed using license plate recognition or a (digital) QR code 17. Corresponding cameras are known from truck toll systems.

[0073] In step iii, the determined and assigned energy consumption level 8 is compared with the permissible maximum energy consumption. This determines whether the existing green energy consumption level 8 sufficiently matches the permissible maximum energy consumption. In one embodiment, there are different qualities of a green position, whereby even with sufficient maximum energy consumption, the green position (at least without an upgrade) is not sufficient to permit entry into the predefined zone 10.

[0074] If the current energy consumption level 8 and the determined maximum energy consumption do not match sufficiently, in step iv. a note is sent to the owner of the motor vehicle 1 concerned by the control center 12 via the transmission interface 5. Regarding the information content of the note, please refer to the previous description in Fig. 2. If the current energy consumption level 8 and the determined maximum energy consumption sufficiently match, in one embodiment, the motor vehicle 1 receives a release. For example, an upcoming energy consumption is then set and / or estimated with the release, which, for example, limits driving in the predefined zone 10 to the released kilometers. Alternatively or additionally, the energy consumption of the motor vehicle 1 in question is monitored until it has left the predefined zone 10 again. For example, this can prevent an inadmissible long stay in the predefined zone 10.

[0075] In Fig. 4 shows a real-time method for ensuring a green position of a motor vehicle 1 by a system 14 for a plurality of motor vehicles 1 in a flowchart. The following description refers to the description for Fig. 1, and in this respect, reference is made to the description therein. The system 14 comprises a testing center 11 with a control center 12 and a transmission interface 5 and is configured to check the green status of a motor vehicle 1, with a certificate 9 with a permissible maximum energy consumption being maintained for the respective motor vehicle 1.

[0076] In a first step A., upon a planned or actual entry of a motor vehicle 1 into a predefined zone 10, the identification file 7 of the motor vehicle 1 is transmitted via its communication interface 4 to the transmission interface 5 of the testing center 11. In this exemplary embodiment, the motor vehicle 1 transmits its identification file 7 of its own accord and without an external request as soon as it enters a predefined zone 10. According to one embodiment, the identification file 7 contains all information relevant to energy consumption regarding the motor vehicle 1, for example the vehicle type, the vehicle identification number, the unladen weight and / or the capacity of the fuel tank and / or the traction battery.

[0077] In the subsequent step B, the control center 12 of the testing center 11 uses the transmission interface 5 to check the green status of a certified permissible maximum energy consumption assigned to the identified motor vehicle 1 and the current energy consumption level 8 of the identified motor vehicle 1. The testing center 11 receives the information on the maximum energy consumption or the corresponding certificate 9. This information is transmitted by the motor vehicle 1 or obtained by the testing center 11 from another body based on the identification file 7. The current energy consumption level 8 is also not necessarily information provided by the motor vehicle 1 itself, but is monitored, for example, by an external body, such as a supervisory authority or a certification body 16.This is possible, for example, via geolocation data and / or via the registration of the (relevant) charging or filling processes.

[0078] The geolocation 15 of a motor vehicle 1 is monitored, for example, by the inspection center 11. Geolocation 15 only occurs when determining the green light status of the motor vehicle 1 is necessary, i.e., when the motor vehicle 1 enters or plans to enter the predefined zone 10 (possibly with authorization). For example, monitoring by the inspection center 11 is initiated by the motor vehicle 1 itself when it enters a predefined region (e.g., a country), wherein the region is larger than the predefined zone 10, in which a valid green light status is mandatory or at least advantageous. Based on the geolocation 15, it is then detected whether the motor vehicle 1 is entering, will enter, or has already entered a predefined zone 10, and the further steps of the real-time process are then triggered.

[0079] In step C, the control center 12 of the inspection center 11 compares whether the determined current energy consumption level 8 corresponds to the permissible maximum energy consumption according to the determined certificate 9 regarding its green status. Based on the comparison, in step D, if there is an insufficient correspondence between the current energy consumption level 8 and the determined maximum energy consumption, the control center 12 transmits a note to the owner of the respective motor vehicle 1 via the transmission interface 5 to the communication interface 4 of the respective motor vehicle 1.

[0080] If, after the comparison, there is sufficient agreement between the current energy consumption level 8 and the determined maximum energy consumption, a release for the predefined zone 10 is transmitted to the relevant motor vehicle 1. For example, entry into or passage through a city or national park is thus permitted.

[0081] In Fig.Figure 5 shows a predefined zone 10 with four motor vehicles 1 located within it and one motor vehicle 1 shortly before entering it in an exemplary map view. The three motor vehicles 1 depicted as passenger cars are traveling within the predefined zone 10 and must have a valid green light status within this zone 10. In one embodiment, however, this is not (permanently) monitored, for example, because only green-lit fuel or charging stations are present within the predefined zone 10. In one embodiment, their geolocation 15 is continuously monitored as long as they remain within the predefined zone 10.

[0082] In one embodiment, the geolocation 15 is monitored exclusively when a motor vehicle 1 enters the predefined zone 10 and, if applicable, when it exits again.

[0083] Motor vehicle 1 on the right in the illustration outside the predefined zone 10 is about to enter and is already in the real-time process for monitoring the status of its green light, so that entry of motor vehicle 1 can still be prevented if the green light is insufficient.

[0084] Motor vehicle 1 on the left in the illustration within the predefined zone 10 near its boundary is about to exit the predefined zone 10. For example, before this motor vehicle 1 leaves the predefined zone 10, it is ensured that costs resulting from the requirements for its green status are settled.

[0085] The invention relates to a real-time method for ensuring a green position of a motor vehicle, comprising the following steps in the order mentioned: a. upon a request from an external transmission interface concerning the status of a green position triggered by the motor vehicle entering a predefined zone, transmission of the identification file and the current energy consumption level of the motor vehicle to the transmission interface; b. in the event of a request from an external transmission interface regarding the status of a green position triggered as a result of the motor vehicle entering a predefined zone, transmit to the external transmission interface the information held by the motor vehicle concerning the certificate concerning the green position of the motor vehicle. and after a comparison of the current energy consumption level with the maximum energy consumption according to the vehicle certificate carried out by a testing centre: and c. from the external transmission interface, receiving a notification for the owner of the motor vehicle in question if the current energy consumption level and the determined maximum energy consumption do not match sufficiently. Furthermore, the invention relates to a real-time method for ensuring a green status of a motor vehicle, which method is carried out by a testing center or a system.

[0086] The real-time method proposed here makes it possible to monitor the validity of a green light status of a motor vehicle using manageable means.
