[0004] Publication DE 10 2018 216 492 A1 discloses a backend device. Summary of the Invention

[0005] The task underlying the present invention is to provide a solution for efficiently forwarding infrastructure assistance data to motor vehicles.

[0006] This task is solved by the corresponding subject matter of the independent claims. Advantageous configurations of the present invention are the subject matter of the respective dependent claims.

[0007] According to a first aspect, there is provided a backend device, comprising:

[0008] a communication facility configured to receive infrastructure assistance data of at least one infrastructure system for a motor vehicle for at least partially automated driving within the infrastructure, the infrastructure system being configured to provide infrastructure-supported assistance to the motor vehicle when the motor vehicle is at least partially automated driving through the infrastructure,

[0009] wherein the communication facility is configured to forward the received infrastructure assistance data to the motor vehicle in compliance with security regulations, wherein the security regulations state that the infrastructure assistance data of the infrastructure system for providing infrastructure-supported assistance to the motor vehicle when the motor vehicle is at least partially automated driving through the infrastructure must be forwarded to the motor vehicle without modification and directly.

[0010] According to a second aspect, there is provided a method for operating a backend device according to the first aspect, the method comprising the following steps:

[0011] receiving, by the communication facility, infrastructure assistance data of at least one infrastructure system for a motor vehicle for at least partially automated driving within the infrastructure, the infrastructure system being configured to provide infrastructure-supported assistance to the motor vehicle when the motor vehicle is at least partially automated driving through the infrastructure,

[0012] The communication facility forwards the received infrastructure assistance data to the motor vehicle in compliance with the security regulations, where the security regulations state that the infrastructure assistance data of the infrastructure system for supporting the motor vehicle during at least partially automated driving of the motor vehicle through the infrastructure must be forwarded to the motor vehicle without modification and directly.

[0013] According to a third aspect, there is provided a computer program comprising instructions which, when the computer program is implemented by a computer, such as the backend device according to the first aspect, cause the computer to implement the method according to the second aspect.

[0014] According to a fourth aspect, there is provided a machine-readable storage medium on which the computer program according to the third aspect is stored.

[0015] The present invention is based on and includes the following recognition: the above task is solved in such a way that the backend device forwards the infrastructure assistance data to the motor vehicle without modification and directly. This means that there is no unnecessary delay on the backend device side when forwarding the infrastructure assistance data to the motor vehicle. By forwarding the infrastructure assistance data without modification, i.e., without being changed, technical advantages such as the following can be achieved: the specified security requirements can be efficiently met.

[0016] Therefore, in particular, the following technical advantage is achieved: the backend device can efficiently forward the infrastructure assistance data to the motor vehicle.

[0017] Therefore, the solution described here is particularly configured such that: the infrastructure system for supporting the motor vehicle during at least partially automated driving of the motor vehicle through the infrastructure does not directly send the infrastructure assistance data to the motor vehicle. Instead, it is particularly configured such that: the infrastructure system sends the infrastructure assistance data to the backend device, and then the backend device forwards the received infrastructure assistance data to the motor vehicle without modification and directly.

[0018] So far, it is like this: Such infrastructure systems send their infrastructure assistance data directly to motor vehicles respectively. As the number of such infrastructure systems increases, there will be a corresponding number of infrastructure systems that will thus communicate directly with motor vehicles, that is, in particular, send infrastructure assistance data to motor vehicles. This may incur huge technical costs on the side of motor vehicle manufacturers or OEMs ("Original Equipment Manufacturer", that is, the initial equipment manufacturer or original equipment manufacturer). These costs may be, for example, because: Communication interfaces for communicating with infrastructure systems on the motor vehicle side must be implemented and maintained. Therefore, motor vehicle manufacturers or OEMs may, for example, decide to restrict externally initiated access to motor vehicles to a back-end device. This means, for example, that communication with motor vehicles can only be carried out via such a back-end device.

[0019] Infrastructure systems for supporting assistance by the infrastructure when a motor vehicle drives through the infrastructure at least partially automatically rely on: Specific safety requirements being met. Therefore, the running time for sending infrastructure assistance data to motor vehicles is not allowed to be too long. For example, it must be ensured that: The infrastructure assistance data is not changed on the path to the motor vehicle.

[0020] The safety requirements are defined or specified, for example, according to ASIL and / or according to SIL.

[0021] The abbreviation "ASIL" stands for the English term "Automotive Safety Integrity Level", which can be translated into German as "Automotive" ". "Automotive Safety Integrity Level" is a key component of the standard ISO 26262. ASIL is divided into four different ASIL risk levels, which are marked as ASIL-A, ASIL-B, ASIL-C, and ASIL-D respectively.

[0022] The abbreviation "SIL" stands for the English term "Safety Integrity Level", which can be translated into German as "Safety Integrity Level" is a key component of the standard IEC EN 61508. SIL is divided into four different SIL risk levels, which are marked as SIL-1, SIL-2, SIL-3, and SIL-4 respectively.

[0023] On the back-end device side, it is ensured that the infrastructure assistance data sent by the infrastructure system is unchanged and directly forwarded by the back-end device to the motor vehicle, whereby it can be ensured in an efficient and advantageous manner that such safety requirements according to ASIL and / or according to SIL are met.

[0024] For example, at least partially automated driving functions of a motor vehicle rely on the fact that specific infrastructure assistance data is as real-time as possible. Such at least partially automated driving functions of a motor vehicle rely in particular on the fact that the infrastructure assistance data has not been changed again after being generated and sent by the infrastructure system, because for example at least partially automated driving functions expect this infrastructure assistance data in specific formats so that this infrastructure assistance data can be processed accordingly. Thus, the solution described here enables in an advantageous manner at least partially automated driving functions of a motor vehicle to work efficiently and safely using such infrastructure assistance data.

[0025] The infrastructure system is, for example, an AVP system. The infrastructure system is, for example, an IAD system.

[0026] The abbreviation "AVP" stands for "Automated Valid Parking" and can be translated as "automatic parking process". The abbreviation "IAD" stands for "Infrastructure Assisted Driving" and can be translated as "infrastructure-supported driving" or "infrastructure-assisted driving".

[0027] Thus, the infrastructure system is a system that assists the motor vehicle when the motor vehicle is driving at least partially automatically through the infrastructure. Thus, the motor vehicle is assisted by the infrastructure when it is driving at least partially automatically through the infrastructure.

[0028] To this end, the infrastructure system generates infrastructure assistance data, based on which the motor vehicle can, for example, drive at least partially automatically.

[0029] Assistance supported by the infrastructure in particular means providing the motor vehicle with infrastructure assistance data. The motor vehicle can, for example, derive behavior commands based on the infrastructure assistance data. The motor vehicle can, for example, decide for itself what to do based on the infrastructure assistance data.

[0030] Infrastructure assistance data includes, for example, one or more of the following data elements: control instructions for at least partially automating the lateral and / or longitudinal guidance of a motor vehicle, remote control instructions for at least partially remotely controlling the lateral and / or longitudinal guidance of a motor vehicle, activation instructions for at least partially automating, in particular fully automating, the driving of a motor vehicle in a parking lot or in a specific area of the infrastructure in general at a specific time, target trajectories for the motor vehicle, target positions within a parking lot or within the infrastructure in general, environmental data representing the environment of the motor vehicle, and regulations on what the motor vehicle should do. The regulation stipulates, for example, whether the motor vehicle is allowed to drive or must stop, for example.

[0031] At least partially automated driving of a motor vehicle within the infrastructure is driving of the motor vehicle in a situation where the motor vehicle is at least partially automatically guided. Thus, the motor vehicle is driven within the infrastructure while being at least partially automatically guided.

[0032] The expression "at least partially automated guidance" includes one or more of the following situations: assisted guidance, partially automated guidance, highly automated guidance, fully automated guidance. Thus, the expression "at least partially automated" includes one or more of the following expressions: assisted, partially automated, highly automated, fully automated. Thus, at least partially automated guidance of a motor vehicle includes at least partially automated control of the lateral and / or longitudinal guidance of the motor vehicle.

[0033] Assisted guidance means that the driver of the motor vehicle continuously performs the lateral or longitudinal guidance of the motor vehicle. The corresponding other driving task (i.e., the control of the longitudinal or lateral guidance of the motor vehicle) is automatically executed. This means that during assisted guidance of the motor vehicle, either the lateral or the longitudinal guidance is automatically controlled.

[0034] "Partially automated guidance" means that, in specific situations (e.g., driving on a highway, driving within a parking lot, overtaking an object, driving within a lane determined by lane markings) and / or during a certain time period, the longitudinal and lateral guidance of the motor vehicle is automatically controlled. The driver of the motor vehicle does not have to manually control the longitudinal and lateral guidance of the vehicle himself. However, the driver must continuously monitor the automatic control of the longitudinal and lateral guidance so that he can manually intervene when needed. The driver must be ready to fully take over the guidance of the motor vehicle at any time.

[0035] "Highly automated guidance" means that, in certain situations over a certain period of time (e.g., driving on a highway, driving within a parking lot, overtaking an object, driving within a lane determined by lane markings), the longitudinal and lateral guidance of a motor vehicle is automatically controlled. The driver of the motor vehicle does not have to manually control the longitudinal and lateral guidance of the vehicle himself. The driver does not have to continuously monitor the automatic control of the longitudinal and lateral guidance so that he can manually intervene when needed. A takeover request is automatically output to the driver to take over the control of the longitudinal and lateral guidance when needed, especially with sufficient time margin. Therefore, the driver must potentially be able to take over the control of the longitudinal and lateral guidance. The boundaries of the automatic control of the longitudinal and lateral guidance are automatically recognized. In the case of highly automated guidance, it is not possible to automatically reach the state with the least risk in every output situation.

[0036] "Fully automated guidance" means that, in certain situations (e.g., driving on a highway, driving within a parking lot, overtaking an object, driving within a lane determined by lane markings), the longitudinal and lateral guidance of a motor vehicle is automatically controlled. The driver of the motor vehicle does not have to manually control the longitudinal and lateral guidance of the motor vehicle himself. The driver does not have to monitor the automatic control of the longitudinal and lateral guidance so that he can manually intervene when needed. The driver is automatically requested to take over the driving task (control the lateral and longitudinal guidance of the motor vehicle) before the automatic control of the longitudinal and lateral guidance ends, especially with sufficient time margin. If the driver does not take over the driving task, the system automatically returns to the state with the least risk. The boundaries of the automatic control of the longitudinal and lateral guidance are automatically recognized. In all situations, the system can automatically return to the state with the least risk.

[0037] The terms "assistieren" and "unterstützen" can be used synonymously.

[0038] The abbreviation "at least one" means "one or more".

[0039] For example, it is set that one or more environmental sensors are spatially distributed within the infrastructure, and they sensorially detect their respective surroundings or environment and output environmental data corresponding to or based on the sensorially detected data, and these environmental data describe the respective environments of these environmental sensors. The infrastructure system generates infrastructure assistance data based on such environmental data, for example.

[0040] The environmental sensor is, for example, one of the following environmental sensors: radar sensor, ultrasonic sensor, lidar sensor, magnetic field sensor, infrared sensor, image sensor, in particular the image sensor of a video camera device, chemical sensor, temperature sensor, acoustic sensor, such as a microphone, gas sensor, such as a carbon monoxide sensor or a carbon dioxide sensor.

[0041] In one embodiment of the backend device, it is provided that the security regulations are implemented in the communication facility.

[0042] This causes, for example, the following technical advantage: The communication facility can efficiently learn about the security regulations.

[0043] In one embodiment of the backend device, it is provided that the backend device includes a control facility, which is configured to control the communication facility based on the security regulations such that the communication facility forwards the infrastructure assistance data of the infrastructure system, which is used for infrastructure-supported assistance of the motor vehicle when the motor vehicle drives at least partially autonomously through the infrastructure, to the motor vehicle without modification and directly.

[0044] This causes, for example, the following technical advantage: The security regulations can be efficiently met.

[0045] For example, the security regulations are implemented in the control facility.

[0046] The infrastructure assistance data is included in a message, for example.

[0047] For example, the security regulations are implemented in the corresponding firmware, in particular in the firmware of the backend device and / or the communication facility and / or the control facility and / or the inspection facility described below and / or the communication facility communication interface.

[0048] In one embodiment of the backend device, it is provided that the security regulations are integrated in a message including infrastructure assistance data, wherein the communication facility is configured to receive the message from the infrastructure system and read out the security regulations from the message.

[0049] This causes, for example, the following technical advantage: The communication facility can efficiently learn about the security regulations that need to be met.

[0050] Therefore, according to this embodiment, it is provided that the infrastructure system generates a message and sends it to the backend device, wherein the message includes infrastructure assistance data, and wherein the security regulations are integrated in the message.

[0051] In one embodiment of the backend device, it is provided that the security regulations are integrated at a predetermined position in the message, wherein the communication facility is configured to read out the security regulations at the predetermined position.

[0052] This causes, for example, the following technical advantage: The communication facility can efficiently read out the safety regulations from the message.

[0053] In one embodiment of the backend device, it is provided that the communication facility has a plurality of communication interfaces, wherein at least one of the plurality of communication interfaces is configured to receive infrastructure assistance data of an infrastructure system for providing infrastructure-supported assistance to a motor vehicle when the motor vehicle is at least partially automatically driven through the infrastructure, such that the communication facility is configured to, when receiving infrastructure assistance data of an infrastructure system for providing infrastructure-supported assistance to a motor vehicle when the motor vehicle is at least partially automatically driven through the infrastructure, in particular a message comprising infrastructure assistance data, forward the received infrastructure assistance data to the motor vehicle unchanged and directly.

[0054] This causes, for example, the following technical advantage: The safety regulations can be efficiently met.

[0055] Therefore, in particular according to this embodiment, it is provided that it is determined or ascertained that the data received by at least one of the plurality of communication interfaces is forwarded to the motor vehicle unchanged and directly. Thus, the safety regulations are in particular implemented in at least one of the plurality of communication interfaces.

[0056] In one embodiment of the backend device, it is provided that the communication facility is configured to receive a notification message of an infrastructure system for providing infrastructure-supported assistance to a motor vehicle when the motor vehicle is at least partially automatically driven through the infrastructure, the notification message informing of the infrastructure assistance data of the infrastructure system for the motor vehicle, wherein the communication facility is configured to, when receiving the infrastructure assistance data of the infrastructure system for the motor vehicle, forward the received infrastructure assistance data to the motor vehicle unchanged and directly based on the notification message.

[0057] This causes, for example, the following technical advantage: The safety regulations can be efficiently met.

[0058] Therefore, in particular according to this embodiment, it is provided that the infrastructure system notifies that it sends infrastructure assistance data.

[0059] The notification message indicates, for example, a future time period during which the infrastructure system sends infrastructure assistance data, such that the infrastructure assistance data received by the communication facility during this time period is forwarded to the motor vehicle unchanged and directly.

[0060] For example, before the infrastructure system sends infrastructure assistance data each time, it sends a notification message. This means, for example, that the infrastructure system notifies the infrastructure assistance data each time.

[0061] The notification message is received, for example, on the same communication interface as the received infrastructure assistance data, or on another communication interface of the communication facility.

[0062] Generally, the communication facility includes one or more communication interfaces, such as the first and second communication interfaces described below.

[0063] In an embodiment of the backend device, it is provided that: the communication facility has a first communication interface and a second communication interface, wherein the first communication interface is configured to receive infrastructure assistance data from the infrastructure system, and wherein the second communication interface is configured to forward the received infrastructure assistance data to the motor vehicle in accordance with security regulations.

[0064] This causes, for example, the following technical advantages: the infrastructure assistance data can be received and forwarded efficiently. Therefore, according to this embodiment, it is provided that: there are two communication interfaces on the backend device side. The first communication interface is configured for communication between the backend device and the infrastructure system. The second communication interface is configured for communication between the backend device and the motor vehicle.

[0065] The communication facility is configured, for example, to communicate via a wireless communication network. Therefore, for example, infrastructure assistance data can be received from the infrastructure system via the wireless communication network. Therefore, for example, the infrastructure assistance data can be forwarded to the motor vehicle via the wireless communication network.

[0066] The wireless communication network includes, for example, a mobile radio network and / or a WLAN network.

[0067] The first communication interface and / or the second communication interface are, for example, a WLAN network interface or a mobile radio network interface, respectively, or include one or more such interfaces.

[0068] In an embodiment of the backend device, it is provided that: the security regulations are implemented in the communication facility and / or in the backend device and / or in the control facility and / or in one or more communication interfaces and / or are implemented or integrated in the message and / or are implemented in one of the above-mentioned firmware and / or are implemented in the inspection facility. Therefore, there are multiple possibilities, for example, for the communication facility to know that it must forward the infrastructure assistance data of the infrastructure system to the motor vehicle without modification and directly, and / or for example, how the backend device can work or operate according to the security regulations.

[0069] The communication interface of the communication facility is, for example, a WLAN network interface or a mobile radio network interface, or includes one or more such interfaces.

[0070] In one embodiment of the backend device, it is provided that the backend device includes an inspection facility which is configured to check whether security regulations are met.

[0071] This causes, for example, the following technical advantage: It is possible to efficiently check whether security regulations are met.

[0072] For example, it is provided that the communication facility is configured to end or interrupt the forwarding of infrastructure auxiliary data when the inspection result indicates that the security regulations are not met. Thus, for example, the following technical advantage can be achieved: It is possible to efficiently ensure that potentially insecure data is not forwarded to the motor vehicle.

[0073] If no infrastructure auxiliary data is forwarded to the motor vehicle anymore, then the motor vehicle no longer receives any infrastructure auxiliary data. This is, for example, a sign on the motor vehicle side for the following situation: An error must have occurred on the backend device side and / or on the infrastructure system side, so that an emergency plan can be implemented in the motor vehicle. For example, the motor vehicle can be transferred to a safe state, for example, a stopped state, in such a case. For example, the motor vehicle can request the driver of the motor vehicle to take over the guidance of the motor vehicle in such a case.

[0074] The description of the backend device similarly applies to the method and vice versa. This particularly means that the method features are derived from the features of the backend device and vice versa. Thus, the technical functions of the method are similarly derived from the corresponding technical functions of the backend device and vice versa.

[0075] In one embodiment of the method, it is provided that the security regulations are implemented in the communication facility.

[0076] In one embodiment of the method, it is provided that the security regulations are integrated in a message including infrastructure auxiliary data, where the message is received by the communication facility from the infrastructure system and the security regulations are read out by the communication facility from the message.

[0077] In one embodiment of the method, it is provided that the security regulations are integrated at a predetermined position in the message, and the security regulations at the predetermined position are read out by the communication facility.

[0078] In one embodiment of the method, it is provided that the communication facility has a first communication interface and a second communication interface, where the infrastructure auxiliary data is received from the infrastructure system by the first communication interface and the received infrastructure auxiliary data is forwarded to the motor vehicle in compliance with the security regulations by the second communication interface.

[0079] In one embodiment of the method, it is provided that the backend device includes an inspection facility, wherein the inspection facility checks whether the security regulations are met.

[0080] In one embodiment of the backend device, it is provided that the backend device is configured in programming technology to execute a computer program according to the third aspect.

[0081] In one embodiment of the backend device, it is provided that the backend device is configured to execute the method according to the second aspect.

[0082] The method according to the second aspect is, for example, a computer-implemented method. For example, the method according to the second aspect will be implemented or has been implemented on the backend device.

[0083] The infrastructure includes, for example, one or more of the following infrastructure elements: parking lots, highways, nodes, intersections, entrances, exits, roundabouts, roads, intersections, merges, highway entrances, highway exits, tunnels, tunnel entrances, tunnel exits, construction sites, lane constrictions, bridges, bridge approaches.

[0090] Figure 6 By Figure 5 Exemplary forwarding of a message including infrastructure assistance data by a third backend device.

[0091] In the following, the same reference numerals may be used for the same features. Detailed Description of the Invention

[0092] Figure 1 The first backend device 101 is shown, including:

[0093] A communication facility 103 is configured to receive infrastructure assistance data of at least one infrastructure system for a motor vehicle that is at least partially autonomously driven within the infrastructure, the infrastructure system being configured to provide infrastructure-supported assistance to the motor vehicle when the motor vehicle is at least partially autonomously driven through the infrastructure.

[0094] Wherein, the communication facility 103 is configured to forward the received infrastructure assistance data to the motor vehicle in compliance with safety regulations, wherein the safety regulations state that the infrastructure assistance data of the infrastructure system for providing infrastructure-supported assistance to the motor vehicle when the motor vehicle is at least partially autonomously driven through the infrastructure must be forwarded to the motor vehicle without modification and directly.

[0095] Therefore, the communication facility 103 is particularly configured to receive infrastructure assistance data from the infrastructure system and forward it to the motor vehicle without modification and directly.

[0096] Forwarding includes, for example, sending the infrastructure assistance data to the motor vehicle, particularly via a wireless communication network.

[0097] Without modification means, for example, that the checksum of the received infrastructure assistance data is the same as the checksum of the forwarded infrastructure assistance data.

[0098] Therefore, the infrastructure assistance data is particularly routed by the communication facility.

[0099] Directly means, in particular, forwarding the infrastructure assistance data to the motor vehicle in response to receiving the infrastructure assistance data. Directly thus means that no unnecessary delay is allowed except for delays that are technically inevitable.

[0100] Figure 2 A second backend device 201 is shown, including:

[0101] A communication facility 203 is configured to receive infrastructure assistance data of at least one infrastructure system for a motor vehicle that is at least partially autonomously driven within the infrastructure, the infrastructure system being configured to provide infrastructure-supported assistance to the motor vehicle when the motor vehicle is at least partially autonomously driven through the infrastructure.

[0102] Wherein, the communication facility 203 is configured to forward the received infrastructure assistance data to the motor vehicle in compliance with safety regulations, wherein the safety regulations state that the infrastructure assistance data of the infrastructure system for providing infrastructure-supported assistance to the motor vehicle when the motor vehicle is at least partially autonomously driven through the infrastructure must be forwarded to the motor vehicle without modification and directly.

[0103] The communication facility 203 includes a first communication interface and a second communication interface. Among them, the first communication interface 205 is configured to receive infrastructure assistance data from the infrastructure system, and among them, the second communication interface 207 is configured to forward the received infrastructure assistance data to the motor vehicle in compliance with security regulations.

[0104] Figure 3 A flowchart showing a method for operating a backend device according to the first aspect is shown. The method includes the following steps:

[0105] The communication facility receives 301 infrastructure assistance data of at least one infrastructure system for a motor vehicle that is at least partially autonomously driven within the infrastructure. The infrastructure system is used to provide infrastructure-supported assistance to the motor vehicle when the motor vehicle is at least partially autonomously driven through the infrastructure.

[0106] The communication facility forwards 303 the received infrastructure assistance data to the motor vehicle in compliance with security regulations. Among them, the security regulations state that the infrastructure assistance data of the infrastructure system for providing infrastructure-supported assistance to the motor vehicle when the motor vehicle is at least partially autonomously driven through the infrastructure must be forwarded to the motor vehicle without modification and directly.

[0107] Figure 4 A machine-readable storage medium 401 is shown, on which a computer program 403 is stored. The computer program 403 includes instructions that, when the computer program 403 is executed by the computer, cause the computer to execute the method according to the first aspect.

[0108] Figure 5 A motor vehicle 501 is shown during at least partially autonomously guided driving within the infrastructure 503. The infrastructure 503 includes a road 505 on which the motor vehicle 501 drives. The road 505 is, for example, a highway or, for example, a rural road. The infrastructure 503 may, for example, include a parking lot such that the motor vehicle 501 drives, for example, inside the parking lot.

[0109] A video camera device 507 including an image sensor 509 is arranged within the infrastructure 503. The video camera device 507 captures video images of the environment of the motor vehicle 501 and sends these video images to an infrastructure system 511 that is used to provide infrastructure-supported assistance when the motor vehicle is at least partially autonomously driven through the infrastructure 503. When the motor vehicle 501 drives, for example, inside the parking lot, the infrastructure system 511 is, for example, an AVP system; or when the motor vehicle 501 drives, for example, on a road, especially on a highway, the infrastructure system 511 is, for example, an IAD system.

[0110] The infrastructure system 511 obtains infrastructure assistance data based on the video images of the video camera device 507 and sends this infrastructure assistance data to a third back-end device 513 including a communication facility 515, which is accordingly arranged as has been set forth within the scope of this specification.

[0111] The communication facility 515 receives the infrastructure assistance data sent by the infrastructure system 511 and forwards this infrastructure assistance data to the motor vehicle 501 without modification and directly.

[0112] Figure 6 The motor vehicle 501, the infrastructure system 511, and the third back-end device 513 are shown when forwarding a message 601 including infrastructure assistance data, and the message is Figure 6 symbolically shown by 0 and 1.

[0113] The message 601 including infrastructure assistance data is generated by the infrastructure system 511 and sent by the infrastructure system 511 to the back-end device 513. The communication facility 515 receives the message 601 and forwards the message directly and without modification to the motor vehicle 501. "The message 601 is forwarded to the motor vehicle 501 without modification by the communication facility 515" is Figure 6 shown by "0 and 1 are not changed during the forwarding process".
