It has data related to that part. Vehicle components, also referred to briefly as parts below, for example 5 These could be systems that enable the vehicle to be driven autonomously. For example, a such as a radar system or a LIDAR system, for detecting objects around the vehicle Sensor systems for this purpose are included. Vehicle components also include a braking system, a steering system. It may include a system or a drive system. Preferably, at least one relevant communication unit for communication units, and at least one relevant vehicle component for vehicle components. It is allocated to the component. This situation concerns the allocation of the relevant communication unit to the relevant communication unit. the relevant component (hereinafter also referred to as the corresponding component) data for processing, in particular for control and / or regulation This means that the system is configured to receive at least the relevant data via the pathway. 15 income. The relevant communications unit can process the received relevant data and / or the corresponding relevant components. It can be forwarded to the control unit. Depending on a possible configuration, the relevant communication unit will forward it to the relevant department. 20 to check and / or adjust the corresponding relevant component based on the data. It can be edited and configured. In particular, the relevant communication unit, the corresponding relevant It can be integrated into the component's control unit. In addition, the relevant communication unit is responsible for processing at least one other relevant component from among the components, in particular other relevant data for monitoring and / or regulation, data bus 25 through the system, communication units to at least another relevant communication unit It can be configured to send. The relevant other communication unit is allocated to the relevant other component. Other relevant data are collected to describe a state of the relevant component, in particular. It includes sensor data. Similarly, the relevant data is transmitted to the corresponding communication unit. 30 This data may include, in particular, sensor data. In other words, communication units, each assigned to one of the components, correspond to... This can be understood as the transmitter and / or receiver unit of the relevant component. 35 3 According to a possible configuration, the relevant data and / or other relevant data will be routed through the data bus system. These messages can be sent in the form of the messages mentioned above. The data bus system facilitates the transfer of relevant data and / or other related data between communication units. It has at least one common transmission path for the purpose of modification. In principle, bus 5 The system can be a parallel or serial data bus system. Preferably, the communication units are data buses. If priority data is to be sent via the system, the transmission of the data It is configured to cut off communication. For this purpose, each of the communication units has the relevant communication... the relevant shipment confirmation of the unit will be checked and depending on the result of this check stopping or resuming the sending of data, especially one of the messages 10 For this purpose, a relevant communication program containing instructions is stored. If the bus system is configured as a parallel bus system, the common The transmission path preferably consists of many signal lines running side-by-side. To transmit messages. Synchronized information is transmitted via signal lines. 15 In many cases, the bus system takes the form of a serial bus system, specifically a CAN. It is organized as a data bus system. Advantageously, the data bus system has equal communication units. It is configured to be in a "multiple" configuration. In other words, the data bus system is preferably configured to be "multiple". It can be operated according to the "main principle". Preferably, each of the communication units is a data bus system 20 sending messages by sending dominant bits and recessive bits via It is structured in such a way that a dominant bit is used, and both bits are sent simultaneously. In this case, it overwrites a recessive bit. The first communication unit is advantageously configured to generate messages. Possible 25 According to the structure, each of the communication units is designed to create messages. It is configurable. In particular, the entire content of the data fields of a large number of messages. This ensures that all related data is fully covered. Each message should preferably be... It has a message identifier. The relevant message identifier is, for example, an 11-bit format. or it can be formatted as a 29-bit format. Based on the relevant message identifier, 30 the exemplary communication unit of communication units, the exemplary message of the relevant message It can verify whether it is related to the communication unit. The message is advantageous. with the help of identifiers, via a data bus system between communication units Messages are given priority over other messages that can be modified. 35 4 The relevant message identifier can be stored in an arbitration area for that message. Additionally, the relevant... The message has a corresponding checksum field. According to the invention, the relevant data field of the relevant message is the relevant part of the data contained in the relevant message. To identify the relevant message, the relevant data field is in the first predetermined position 5 To the relevant identifier, all data in the second predefined position of the relevant data field. the relevant indicator for the quantity of the parts and the third prior to the relevant data field It has the data belonging to the relevant data section in its designated position. Because the messages have the relevant identifier, the second communication unit is linked to 10 the data is organized separately in the form of data segments by the first communication unit Even though it has been sent, you can completely reorganize the linked data and the linked It can function as a single unit. In this way, the size of the relevant message that can be sent via the data bus system is limited to 15. However, content-related data can be transmitted via the data bus system. It becomes possible to exchange data between communication units. Linked data, for example, can be exchanged between units. It may include firmware. Alternatively, or additionally, related data can be a computer. a model designed to approximate physical operations, especially in at least one of its components It may include data for determining the model. The computer model should preferably be an artificial intelligence 20 It can be organized in the form of a module (KI module). Here, the KI module specifically refers to an artificial neuron. It can simulate a neural network. A neural network, in particular, has a large number of neurons, layers of neurons, and each one of them is linkage weights, which indicate the strength of connections between neurons. In this case, the linked data includes the connection weight values and neuron layers. It may contain information and neurons. 25 Linked data can specify, for example, a data object structure. A data object structure can be, for example, the number of hidden layers in the neural network, the number of neurons in the relevant hidden layer and / or for example, the type of activation function of the relevant neuron in the neural network, such as in a computer. It defines a structure of the model. 30 The first communication unit receives the connected data, preferably from an external computer system, for example. It can receive it from the cloud. Advantageously, the primary communication unit receives the connected data, data It is structured to separate into parts, especially to divide. 35 Linked data and data segments can be in text format or, for example, via a data bus system. It can be sent in binary format. Linked data can be transmitted as text via the data bus system. If the data is sent in the form of data portions in a format or binary format, the second The communication unit preferably presents the data sections in the form of text sections or binary sections. It is structured to combine. 5 Specifically, the second communication unit is used to create a sequence from the data portions. It can classify parts of the data based on identifiers. Second communication unit. preferably, data for the purpose of reconstructing, or reorganizing, the linked data. It combines the data segments in the correct order. 10 Due to the structuring of the relevant data field of the relevant message, the second communication unit, the identifier and the relevant indicator for the number of all parts of the data and the data It can identify, read, and process the relevant portion of this type of data coming from the field. It can process, especially store. 15 The first predetermined position of the data fields, all data fields of the messages In terms of respect, it is the same position. The same situation applies to the second and third prior data fields. This applies to the specified position. In this way, there is a common approach to the data fields of the messages. The data structure is provided. Here, the first predetermined position is the relevant data field. It is not mandatory for it to be at the beginning. The first, second and third are predetermined 20 The words “first”, “second” and “third” relating to the position are only used in different data fields. It refers to the positions. Therefore, the second position of the relevant data field is the position of the relevant data field. It comes before the first position. The common data structure specifically specifies which byte or 25 of the relevant data field the relevant identifier belongs to. bytes, the relevant indicator for the number of all parts of the data and the relevant data. It can be specifically defined in advance by specifying where the data belonging to those sections is stored. For example... The relevant identifier is in the first byte of the relevant data field, representing the number of all parts of the data. The relevant indicator is in the second byte of the relevant data field, and the data pertains to the relevant part of the data. It can be stored in the bytes of the relevant data field after the second byte. 30 The first position specifically involves the relevant byte in which the corresponding identifier of the relevant data field is stored. It can be predetermined. In particular, the first position is the relevant identifier of the relevant data field. It can be predetermined by the position of the first bit of the byte in which it is stored. 35 6 The second position specifically relates to the number of all parts of the data in the relevant data field. The relevant byte in which the relevant indicator is stored can be predetermined. Specifically, the second position. the relevant indicator for the number of all parts of the data in the relevant data field It can be predetermined by the position of the first bit of the byte in which it is stored. The third position, for example, refers to the relevant parts of the data within the relevant data field. The relevant bytes in which it is stored can be determined in advance. Specifically, the third position, the relevant data. the first bit of the relevant byte where the data belonging to the relevant part of the field's data is stored Its position can be determined in advance. The second communication unit is preferably designed to process messages, taking into account a common data structure. It is structured. For example, the second communication unit processes the relevant data field signals, specifically the relevant data. separate area located in or starting from the first predetermined position of the area. the bits will be read in their entirety, preferably decoded, and the corresponding identifier will be used. It can process the relevant data field of the message in a way that it will be stored. Preferably with "Decryption", 15 from a format in which the relevant data field is transmitted via the data bus system, for example binary from one format to another, where the second communication unit also processes the information from the relevant data field. transformation is meant. Similarly, the second communication unit signals the relevant data field signals, specifically those of the relevant data field 20. separate bits located in or starting from the second predetermined position will be read in its entirety, preferably deciphered, and the number of all parts of the data will be recorded. It can process the relevant data field of the message in such a way that the relevant indicator is stored. Similarly, the second communication unit signals the relevant data field signals, specifically those of the relevant data field 25 the separate bits located in or starting from the third predetermined position will be read in its entirety, preferably deciphered, and the data will be treated as the relevant portion of the data. It can process the relevant data field of the message in a way that it will be stored, where the relevant part of the data is located. It can be identified via the relevant identifier. The second communication unit should preferably transmit the relevant message when the second one detects the common data structure. The data field can initiate a processing operation in this way. The second communication unit is preferably the relevant one. It is configured to detect a common data structure based on the message identifier. Possible According to a structure, message identifiers encompass all the messages mentioned above. They may be similar in this respect. In addition to the messages mentioned above, other messages, 35 7 It is obvious that these messages can be sent to and received from the data bus system. These other messages, They have different message identifiers compared to other messages. Another advantageous structure involves communication units having at least a second communication unit, to receive messages and generate a confirmation message and transmit it via the data bus system 5 It is configured to send. The confirmation message is the data that the second communication unit will send. It includes a data field that has an indicator of which data portions it has not yet received. This situation means that messages can be transmitted independently of each other over time, for example, directly. The advantage is that they can be sent one after another by the first communication unit. It has the ability to quickly transmit linked data from the first communication unit to the second communication unit. This allows the message to be transmitted in some way. The first communication unit receives the confirmation message and Preferably depending on the confirmation message, the relevant data that the second communication unit has not yet received. It resends the parts. For this purpose, the first communication unit is advantageously positioned as described above. It creates other messages structured similarly to the messages mentioned, where The data fields of other messages contain the relevant 15 data that the second communication unit has not yet received. It has parts. In this configuration, the data field of the confirmation message is derived from the linked data of the second communication unit. It is ensured that it has an indicator of which data segments it has already received. In this case, the first communication unit determines which 20 of the second communication unit is based on this indicator. It can detect that it has not yet received the data portions. In general, the second communication unit The indicator shows which data portions have already been retrieved from the linked data. at the time, which data portions of the linked data did the second communication unit not yet receive? It can also be understood as an indication that it has not been received. This situation reveals which parts of the data were not received. It requires knowledge of the information that it generates related data. 25 According to another advantageous structure, at least the second communication unit of the communication unit, to receive relevant messages and a relevant confirmation message in response to receiving the relevant message. It is configured to create and send data via the data bus system. The relevant confirmation message has a corresponding data field. The corresponding data field of the relevant confirmation message is the second 30 It has at least one indication that the communication unit has received the relevant data portion. According to another configuration, the relevant data field of the relevant confirmation message is located via the relevant message. To identify the relevant data portion received by the second communication unit, the relevant confirmation message is included. The data field may have the relevant identifier in its first predetermined position. 35 8 Advantageously, the relevant data field of the relevant confirmation message is also the relevant confirmation. the message contains all the data in the second predefined position of the relevant data field. It has an indicator of the number of its parts. In a development, the relevant data field of the confirmation message is also the relevant confirmation message's data field. The second message is delivered via the relevant message in the third predefined position of the relevant data field. The communication unit may have access to the relevant data portion of the data it receives. The relevant confirmation message should include the number of all parts of the data for the relevant identifier, 10. If it has the indicator and the relevant parts of the data, the second communication An indication of whether the unit has received the relevant data section is preferably the relevant confirmation message. It is stored in the fourth predefined position of the relevant data field. According to one variant of this structure, 15 steps are required to generate the relevant confirmation message. The aforementioned common data structure, with the fourth predefined position can be completed. According to another variant of this structure, the data mentioned above... Its structure also allows for the sending of messages with the help of the first communication unit. The fourth may have a predetermined position. In this case, the relevant message contains the relevant data. A value of “zero” can be found in the fourth position of the field. The second communication unit, the relevant 20 The indicator that the data portion has been received can preferably be arranged in the form of a flag. Here The "zero" value in the flag may mean that the relevant data has not yet been retrieved. The value "one" in the flag means that the relevant data section has been retrieved. The aforementioned common data structure can also be used with the help of the first communication unit 25 having a fourth predetermined position during message sending In this case, this situation is handled by both the first and second communication units. Only a single data structure should be used for the transmission of linked data. It has an advantage in that it is not necessary. This situation facilitates the transmission of linked data. It can reduce complexity in terms of calculation during the process. For example, processing messages 30 Thus, only this single data structure can be defined or declared in a program. is necessary. Generating the relevant confirmation message for the relevant message and sending it via the data bus system. The advantage of sending is that some messages don't have to be sent twice. This could be the case. Advantageously, the first communication unit is only 35, previously... 9 receiving a confirmation message that the sent messages have reached the second communication unit Then, it is arranged to send the next message. First communication. This unit provides this confirmation in response to receiving the relevant message from the second communication unit. You can receive the relevant confirmation messages in the form of a confirmation message. According to an advantageous structure, the relevant message's relevant data field and the relevant confirmation message's relevant The data field has an indicator for identifying linked data. Linked an indicator for identifying data, for example in the form of a number or a string. This structure allows for the transport of numerous different related data via a data bus system. It has the advantage of being able to send, where in any case, the relevant 10 of the data It is divided into parts. In addition, a communication system is proposed. The communication system includes a data bus system and multi- It has a number of communication units, where at least one of the communication units is a primary communication unit. Content-related data transmitted via a data bus system in numerous messages 15 It is configured to send in this format. Linked data is presented as numerous data points. It is separated. The relevant message has a corresponding data field. The corresponding data field is configured and the data is displayed. to define the relevant part in the first predetermined position of the relevant data field at least one relevant identifier, in the second predefined position of the relevant data field a relevant indicator of the quantity of all parts of the data and the relevant data field 20 It possesses data relating to the relevant part of the data in its third predetermined position. In addition, communication units must have at least one secondary communication unit to receive messages and content. In order to reorganize the related identifier and the data in relation to it. to combine parts of data based on the data belonging to the relevant parts of the data It is configured. The first and second communication units are 25 according to one of the variants described above. It is editable. The same applies to the relevant data field of the message. Furthermore, content in a communication system is also a data bus system and a large number of communication units. A method is proposed for sending related data. In this method... The linked data is broken down into numerous data points. The method follows these steps: 30 It has. In the first step, communication units, with the help of the first communication unit, have numerous A message is sent, where the relevant message has a corresponding data field, and the corresponding data field It is structured and the first prefix of the relevant data field is used to define the relevant part of the data. At least one relevant identifier in the specified position, the second prior to the relevant data field 35 is a relevant indicator for the quantity of all parts of the data in the determined position. and the relevant part of the data in the third predetermined position of the relevant data field. It has data. In the second step, the messages are sent from one communication unit to another communication unit. It is obtained with the help of. In the third step, the content-related data is re-entered. Depending on the relevant identifier, parts of the data and the relevant message are organized accordingly. The data from the data sections are combined using a second communication unit. 5 In an advantageous configuration of the method, messages are transmitted sequentially by the first communication unit. They are sent in a sequence. In this structure, a response is received upon receipt of a confirmation message. The process involves sending the next message in a sequence, where the confirmation message is sent. It is sent by the second communication unit and, in turn, the previous message of the messages It has an indication that it has been received. 10 In another structure, messages are transmitted over time by the first communication unit. They are sent independently of each other and in response to receiving a confirmation message. At least some of the data is resent. In this configuration, the confirmation message is the second communication. It is sent by the unit and the second communication unit knows which parts of the data it has not yet received. 15 It has an indication that it hasn't been received. Also, a computer that has instructions that can be executed by one or more processors. The product program is recommended. The execution of the commands depends on the processors described above. It enables the method to be performed according to one of the variants. Preferred configuration examples are shown in more detail based on the following figures: It is explained.

For this purpose, the second communication unit (2) for example, the second communication unit (2) can process or the data bus system (6) a set of message identifiers that it processes when sent, each specifying a type of message. It can store a list of values. 30 Preferably each of the messages (first message (101), second message (102), third message (103)) to a message identifier (message identifier-1 (61), message identifier-2 (62) or It has message identifier-3 (63). The relevant message identifier (message identifier-1 (61), message identifier-2 (62) or message identifier-3 (63)) especially a message (100) 35 16 It functions in such a way as to not recognize the type. The messages (100) are of the same type in all cases. Therefore, in the variant shown in Figure 3, the message identifiers (message identifier-1) (61), message identifier-2 (62) or message identifier-3 (63)) are similar. Message identifiers (message identifier-1 (61), message identifier-2 (62) or message The identifier-3 (63)) is advantageously in the form of a natural number, where, for example, every 5 In this case, it has the value "503". Generally, message identifiers (message identifier-1 (61), message identifier-2 (62) or message identifier-3 (63)), the first other message (301), the second other message (302) or the third other message (303) in a relevant arbitration area It is stored in binary format. The first vehicle component (11) is, for example, to enable the autonomous driving of the vehicle (4). The vehicle may have (4) an onboard computer. For this purpose, the first vehicle component (11) preferably, a computer connected to the first communication unit (1) for data transmission It has a unit (14). The second vehicle component (12) is, for example, one not shown in Figure 1. a camera system including a camera and images detected with the help of the camera 15 There may be an evaluation unit (15) to evaluate. Evaluation unit (15) an assessment that advantageously reflects the images or the content of the images It connects to the second communication unit (2) for the transmission of its files. A possible According to the structure, the second communication unit (2) uses cameras at regular intervals. The detected images can be sent to the data bus system (6). Here the images are sent to the data bus 20 Additional messages can be transmitted in the form of messages with the help of the system (6). The third vehicle component (13) is, for example, to control and / or regulate the drive system. It may be a drive system with a control unit (16). Preferably the control unit (16), 25 for data transmission to control and / or regulate the third vehicle component (13). It is connected to the third communication unit (3). The linked data (20) can update or check the evaluation unit (15), for example. There may be data for updating the unit (16). Therefore, the data (20) may be the first data. part (21), second part (22) and third part (23) of the data, a neural network or 30 executable computer program of the evaluation unit (15) or control unit (16) It can include all information for the purpose of updating, especially modifying, a structure. According to the example, the data (20) show a number of hidden layers of the network, a number of neurons of the related hidden network and It can describe the type of activation function of neurons. Alternatively or additionally data (20) may include compiled files. Second communication unit (2) or third communication 35 17 unit (3) preferably one of the evaluation unit (15) or control unit (16) compiled files to create a computer program to be run on a microchip They can be configured to be combined. To identify the related data (20), the relevant indicator (indicator-4 (51), indicator-5 (52), 5 indicator-6 (53)) preferably, data field (data field-1 (111), data field-2 (112) or data The area-3 (113)) is stored in binary form with the help of the first byte. As shown in Figure 3. According to the structure, the data field (data field-1 (111), data field-2 (112) or data field-3 (113)) the identifier to define the relevant data part preferably the corresponding data The second byte of the field (data field-1 (111), data field-2 (112) or data field-3 (113)) is 10 It is stored in binary form with the help of. Figure 3 shows how to define both linked data (20). indicator and related identifier (identifier-1 (31), identifier-2 (32), identifier-3 (33)) is shown in alphanumeric form for better understanding. In the example structure shown in Figure 3, the relevant data field (data field-1 (111), data field-15 2 (112) or data field-3 (113)) first position of the relevant message (first message (101), second message (102) or third message (103)) the relevant data field (data field-1 (111), data field-2 (112) or data field-3 (113)) can be predetermined via the position of the relevant second byte. To store the indicator for the number of all parts of the data (20) the relevant data The second of the field (data field-1 (111), data field-2 (112) or data field-3 (113)) is 20 the determined position, the relevant message (first message (101), in the variant shown in Figure 3, second message (102) or third message (103)) the relevant data field (data field-1 (111), data Data field-2 (112), data field-3 (113)) can be predefined in the form of the corresponding third byte. The relevant parts of the data (first part of the data (21), second part of the data (22) or The relevant third position regarding the storage of the third part of the data (23), the relevant data 25 the second of the field (data field-1 (111), data field-2 (112) or data field-3 (113)) Its position can be predetermined via the byte following the relevant byte that specifies its position. the relevant part of the data accordingly (first part of the data (21), second part of the data (22)) or the third part of the data (23)), the number of all parts of the data (20) in the relevant data field (data field-1 (111), data field-2 (112) or 30 where the indicator is stored data field-3 (113)) can be stored in the relevant bytes after the said byte. The relevant identifier (identifier-1 (31), identifier-2 (32) or identifier-3 (33)) from the bytes of the data field (data field-1 (111), data field-2 (112) or data field-3 (113)) in which of them is the relevant indicator (indicator-4 (51), indicator-5 (52), 35 18 indicator-6 (53)) and the relevant parts of the data (first part of the data (21), second part of the data the relevant specification regarding the storage of part (22) or third part (23) of the data, The messages (100) can be understood as a common data structure. The messages (100) are this common data its structure example message identifier (message identifier-1 (61), message identifier- 2 (62) or message identifier-3 (63)) is specified. The common data structure of messages (100) is 5 This can be understood as a common type mentioned above. According to an advantageous configuration, the first communication unit (1) is arranged and shown in Figure 3. It is structured to create messages such as (100). Here the first communication unit (1) Firstly, related data (20), in particular three data (10 of the data) using a splitting program in the form of the first part (21), the second part of the data (22) or the third part of the data (23)) It can divide. In addition, the first communication unit (1) provides the connected data (20) in binary format from the start. If not, convert the linked data (20) into a binary format. It can be configured. Parts of the data of the linked data (20) are the first communication unit (1) advantageously, the relevant part of the data (the first part of the data (21), data The second part (22), the third part of the data (23)) will have a maximum size of 8 bytes. It is arranged in this way. In this way, the parts of the data (the first part of the data (21), the second part of the data part (22), third part of the data (23)) especially in a simple way CAN bus message 20 It can be sent as. According to one variant, the first communication unit (1) or communication system (5) Data from a receiver not shown in the figures (20), from an external computer (7) radio can receive signals via (8). The second communication unit (2) is advantageously designed to receive messages (100) and content 25 In order to reorganize the data related to the relevant identifier (20) (identifier-1 (31), identifier-2 (32) or identifier-3 (33)) and the relevant part of the data (of the first part of the data (21), the second part of the data (22) or the third part of the data (23)) depending on the data, parts of the data (20) (first part of the data (21), second part of the data part (22) or third part (23) of the data is configured to combine. Advantageous 30 In this way, the second communication unit (2) messages (100) in each case to the relevant message identifier (message identifier-1 (61), message identifier-2 (62) or message identifier-3 (63)) It defines based on this. In this way, the second communication unit (2) defines the corresponding relevant identifier. (identifier-1 (31), identifier-2 (32) or identifier-3 (33)), the relevant indicator (indicator- 1 (41), indicator-2 (42) or indicator-3 (43)) and the relevant part of the data (20) (the first 35 of the data 19 to read part (21), second part (22) or third part (23) of the data and to process them separately, especially for the purpose of storing them separately, Taking into account the common data structure of the messages (100), the data fields (data field-1 (111), data When reading data field-2 (112) or data field-3 (113)), the relevant data field (data field-1 (111), data field-2 (112) or data field-3 (113)) first, second and third positions 5 He can jump. The second communication unit (2) can advantageously generate a confirmation message (201) and data The system is configured to send the message via (6). The confirmation message (201) is advantageous. In some way, the second communication unit (2) has received which data parts of the linked data (20) 10 It has a data field-4 (211) containing an indicator-7 (271) that indicates that it is true. Indicator-7 (271) can be specified preferably in binary coded form with the help of the confirmation message (201). Figure In the application shown in 4, indicator-7 (271) is equal to six. The number 6 is 21 + 22. It consists of the sum. If Indicator-7 (271) is equal to six, this is the second case. The communication unit (2) received the first part of the data (21) and the second part of the data (22) 15 This means that the second communication unit (2) here confirms the second communication unit (2). until the first time point in which he created his message (201) the first message (101) and the second It is assumed that he received message (102) and has not yet received the third message (103). In addition, data area-4 (211) advantageously has a second communication unit (2) of 20 It has a list (291) of the relevant parts of the data (20) that it did not receive. Shown in Figure 4. In the application example, the third message of the second communication unit (2) at the first time point (103) because it has not yet received the data, the second communication unit (2), the data third Since part (23) has not yet been received, value 3 is entered into the list (291). The confirmation message (201) preferably has a message identifier to detect the confirmation message (201). It has an arbitration area where 4 (261) is stored. Message identifier-4 (261), confirmation the message (201) points to a data structure and in the variant shown in Figure 4, for example It has the value “17”. The first communication unit (1) preferably has the message identifier-4 (261) 30 to detect the confirmation message (201) and to take into account the data structure of the confirmation message (201) It is arranged to read data area-4 (211). Specifically, the first communication unit Indicator-7 (271) can be deciphered by taking into account the data structure of the confirmation message (201). Figure 6 shows the first communication unit (1), the connected data (20) via the data bus system (6). The communication system (5) 35 is configured to send other messages (300) in the form of messages. It shows another variant. Other messages (300) are the first in the example shown in Figure 6. It includes the other message (301), the second other message (302) and the third other message (303). Other Messages (300) are organized in a similar way to messages (100). Therefore, the first other message (301) is the first predetermined 5 of data field-6 (311). an identifier-4 (331) to define the first part of the data (21) in position, All of the data (20) in the second predetermined position of data area-6 (311). an indicator of the number of parts-9 (341) and the third of data field-6 (311) a data field that has the first part of the data (21) in its predetermined position - It has 6 (311). Descriptor-4 (331), in the application case shown in Figures 2 and 6, is 10 to indicate that the first other message (301) covers the first part of the data (21) It has value. Similarly, the second other message (302) is the first predefined one of data field-7 (312). an identifier-5 (332) to define the second part of the data (22) in position 15 All of the data (20) in the second predetermined position of data area-7 (312). an indicator of the number of parts-10 (342) and the third of data field-7 (312) a data field that has the second part of the data (22) in its predetermined position- It has 7 (312). Descriptor-5 (332), in the application case shown in Figures 2 and 6. To indicate that the second other message (302) covers the second part of the data (22), two 20 It has value. Similarly, the third other message (303) is the first predefined one of data field-8 (313). an identifier-6 to define the third part of the data (23) in position (333), all 25 of the data (20) in the second predetermined position of data area-8 (313). an indicator of the number of parts-11 (343) and the third of data field-8 (313) a data field that has the third part of the data (23) in its predetermined position - It has 8 (313). Descriptor-6 (333), in the application case shown in Figures 2 and 6. Pointing out that the third other message (303) covers the third part of the data (23) It has three values. 30 In addition to the elements of the messages (100) shown in Figure 3, each of the other messages (300) one of the relevant data fields (data field-6 (311), data field-7 (312) or data field-8 (313)) in its fourth predetermined position, the related other message (first other message) (301), the relevant 35 regarding the receipt of the second other message (302) or the third other message (303)). 21 It has an indicator. Therefore, data field-6 (311) is the fourth of data field-6 (311). It indicates whether the first other message (301) was received in its predetermined position. It has an indicator-15 (381). Similarly, data field-7 (312) is the fourth predetermined 5 of data field-7 (312). an indicator showing whether the second other message (302) has been received in the position - It has 16 (382). Accordingly, data field-8 (313) is the fourth of data field-8 (313). whether the third other message (303) was received in its predetermined position It has an indicator-17 (383). The fourth of the relevant data field (data field-6 (311), data field-7 (312) or data field-8 (313)) the predetermined position, the relevant data in the example configuration shown in Figure 6. the first byte of the field (data field-6 (311), data field-7 (312) or data field-8 (313)) It is located behind the relevant data field (data field-6 (311), data field-7 (312) or data field-8 (313)) the first, second and third predetermined positions in each case, 15 the first of the relevant data field (data field-1 (111), data field-2 (112) or data field-3 (113)), the relevant data field (data field-6) compared to its second and third predetermined positions. (311) shifts backward by one byte in data field-7 (312) or data field-8 (313)). 20 of the relevant identifiers (identifier-4 (331), identifier-5 (332) or identifier-6 (333)) the relevant data field (data field-6 (311), data field-7 (312) or data field-8 (313)) in which of the bytes or bytes is the relevant indicator (indicator-12 (351), indicator-13 (352), indicator-14 (353)) and the relevant parts of the data (first part of the data) (21), the second part of the data (22) or the third part of the data (23)) is stored. The specification can be understood as a common data structure for other messages (300). Other 25 messages (300) this common data structure example message identifier (message with identifier-5 (361), message identifier-6 (362) or message identifier-7 (363)) It is stated. The common data structure of other messages (300) is the second common type of messages. understandable. Because the other messages (300) are of the same type in every case, as shown in Figure 6 In the variant, message identifiers (message identifier-5 (361), message identifier-6 (362), message identifier-7 (363)) is similar. Message identifiers (message identifier-5 (361), message identifier-6 (362), message identifier-7 (363)) advantageously a It is in the form of a natural number and here, for example, it always has the value "131". Generally 35 22 message identifiers (message identifier-5 (361), message identifier-6 (362) or message identifier-7 (363)), first other message (301), second other message (302) or The third other message (303) is stored in binary format in a relevant arbitration area. In the structure shown in Figure 6, the relevant message (first other message (301), second other 5 the relevant indicator as to whether message (302) or third other message (303) has been received (indicator-15 (381), indicator-16 (382) or indicator-17 (383)), of the relevant indicator (indicator-15 (381), indicator-16 (382) or indicator-17 (383)) in the form of a dual flag It can be configured. The relevant message (first other message (301), second other message (302) or If the third other message (303)) has not yet been received, the relevant indicator is 10 (indicator-15 (381), indicator-16 (382) or indicator-17 (383)) a corresponding flag value is equal to zero. The relevant message (first other message (301), second other message (302) or third other message (303)) during the sending of the relevant message (first other message (301), second because other message (302) or third other message (303)) has not yet been received, the relevant indicator (indicator-15 (381), indicator-16 (382) or indicator-17 (383)) a relevant 15 The flag value is equal to zero. The second communication unit (2) advantageously receives each of the other messages (300) separately. It is structured to receive and process. In particular, the second communication unit (2), the first other Response to the relevant receipt of message (301), second other message (302) and third other message (303) 20 as the first confirmation message (401), the second confirmation message (402) and the third confirmation message (403) is arranged to create and send via the data bus system (6) and It is configured. Here, confirmation messages (401, 402 or 403) are the first of the other messages (300) generally received by the second communication unit (2) with a delay relative to each other. Therefore, they can be created and sent with a time difference relative to each other. 25 Figure 7 shows the data of the second communication unit, the second communication unit (2) and the first other message (301). By changing the indicator-15 (381) of area-6 (311), the first confirmation message (401) This demonstrates a particularly advantageous structure that it can create. Therefore, the second communication unit. It is advantageous to write the value 1 to the flag of indicator-15 (381). Thus Figure 30 7, the first confirmation message (401) is almost identical to the first other confirmation message (301) It shows a variant in which it is arranged. Only the first other message of the second communication unit (2) (301) the first confirmation message about whether it was received (401) belonging to data field-9 (411) Indicator-20 (481) is different from indicator-15 (381) of data field-6 (311). This situation The second communication unit (2) uses the first other 35 to create the first confirmation message (401). 23 insofar as the message (301) has to be changed only minimally It has an advantage. The same situation applies to each of the second other messages (302) or the third other For the second confirmation message (402) and the third confirmation message (403), which are similar to the first message (303) It is valid. Therefore, the first confirmation message (401) is the first predefined one of data field-17 (411). a descriptor-7 to define the first part of the data (21) in position (431), All of the data (20) in the second predetermined position of data field-9 (411). an indicator of the number of parts-17 (441) and the third of data field-9 (411) a data field-10 which has the first part of the data (21) in its predetermined position It has 9 (411). Descriptor-7 (431), in the application case shown in Figures 2 and 7. to indicate that the first confirmation message (401) covers the first part of the data (21) It has value. Similarly, the second confirmation message (402) is the first predefined 15 of data field-10 (412). an identifier-8 (432) to define the second part of the data (22) in position, All of the data (20) in the second predetermined position of data field-10 (412). an indicator of the number of parts-18 (442) and the third of data field-10 (412) a data field that has the second part of the data (22) in its predetermined position- It has 10 (412). Descriptor-8 (432) has 20 in the application case shown in Figures 2 and 7. to indicate that the second confirmation message (402) covers the second part of the data (22) It has two values. Similarly, the third confirmation message (403) is the first prior to data field-11 (413). 25 to define the third part of the data (23) in the determined position to identifier-9 (433), in the second predetermined position of data field-112 (413) An indicator for the number of all parts of the data (20)-19 (443) and data field-11 (413) having the third part of the data (23) in the third predetermined position It has a data field-11 (413). Descriptor-9 (433), implementation shown in Figures 2 and 7. In this case, the third confirmation message (403) covers the third part of the data (23) 30 It has three values to indicate. The relevant data field (data field-9 (411), data field-10 (412) or data field-11 (413)) First confirmation message (401) in the fourth predetermined position, second confirmation message (402) and third confirmation message (403) in each case the other relevant message (first other 35 24 whether message (301), second other message (302) or third other message (303) was received It has an indication of this. Therefore, data field-9 (411) is the fourth of data field-9 (411). It indicates whether the first other message (301) was received in its predetermined position. It has indicator-20 (481). Similarly, data field-10 (412) has data field-10. (412) the second other message (302) is received in the fourth predetermined position 5 It has an indicator-21 (482) which indicates that it was not received. Accordingly, the data field- 11 (413), third other in the fourth predetermined position of data field-11 (413). It has an indicator-22 (483) which indicates whether the message (303) has been received. The first confirmation message (401), the second confirmation message (402) and the third confirmation message (403) are sent every 10 minutes. one of them only, the first other message (301), the second other message (302) or the third other because the relevant indicator (indicator-) is generated upon receipt of the message (303). (481), indicator-21 (482) or indicator-22 (483)) the corresponding flag value is equal to one. Confirmation messages (first confirmation message (401), second confirmation message (402), third confirmation message 15 message (403)) preferably being of the same type as other messages (300) in any case, In the variant shown in Figure 7, the message identifiers (message) of the confirmation messages (400) identifier-8 (461), message identifier-9 (462), message identifier-10 (463)) They are similar. Therefore, message identifiers (message identifier-8 (461), message identifier-9 (462), message identifier-10 (463)), each 20 in the variant shown in the figures. In this case, it has the value "131". Generally, message identifiers (message identifier-8) (461), message identifier-9 (462), message identifier-10 (463)), first confirmation message (401), the second confirmation message (402) or the third confirmation message (403) is a relevant arbitration It is stored in binary format in this field. The first communication unit (1) preferably has the message identifier (message identifier-8 (461), Confirmation messages based on message identifier-9 (462), message identifier-10 (463)) (400) to detect and confirm other messages (300) with the same data structure as the common data structure taking into account the data structure of the messages (400) in each case the data field (data field-9 (411) is configured to read data field-10 (412) or data field-11 (413). Specifically 30 first communication unit, the relevant indicator (indicator-20 (481), indicator-21 (482) or indicator-22 (483)) based on the relevant flag value, the other relevant message (first other that message (301), second other message (302) or third other message (303) has been received can detect. 35 Figure 8 shows how to send content-related data (20) in the communication system (5). It shows the steps of a method for the purpose of. Linked data (20), many data parts, especially The data in the form of the first part (21), the second part (22) and the third part (23) is separated. Such a classification of data (20) before the method described below. This can be done. For example, data from the first communication unit (1) or external computer (7) (20), 5 data parts (first part of data (21), second part of data (22), third part of data (23)) can be separated In the first step, (801) messages (100) or other messages (300), first communication unit (1) It is sent with the help of. 10 In the second step, (802) messages (100) or other messages (300), second communication unit (2) It is sent with the help of. In the third step (803) parts of the data (20), for example the first part of the data (21), 15 of the data second part (22) and third part of the data (23), to the relevant identifier (identifier-1 (31), identifier-2 (32) or identifier-3 (33)) or the relevant identifier (identifier-7 (431), identifier-8 (432) or identifier-9 (433)) and the related message (first message (101), second message (102), third message (103)) or other related message (first other message (301), the relevant part of the data of the second other message (302) or third other message (303)) (data 20 data relating to the first part (21), the second part (22) or the third part (23)) of the data. Depending on the content, the related data (20) are to be reorganized. It is combined with the help of the second communication unit (2). The computer unit (14) of the first communication unit (1) is advantageously located, the computer unit 25 (14) is a monitoring that enables monitoring of the capacity of the bus system (6). It has a module. The computer unit (14) has an advantageous bus system (6) especially messages (100) or other depending on a monitoring result of its capacity The messages (300) are configured to be sent, especially to create and send. The capacity of the data bus system (6) is, for example, above a predetermined threshold value If it is large, the first communication unit (1) can advantageously send other messages (300) sends. If other messages (300) have not yet been received, the first communication unit (1) advantageously, the bus system (6) capacity a predetermined threshold If it exceeds its value, it creates other messages (300). First communication unit (1) 35 26 It sends the other messages (300) with a delay relative to each other. First other message (301), before the second other message (302) and the second other message (302), third It can be sent before the other message (303). But in principle, the other messages (300) During sending, another order of other messages (300) may be applied. At this point, in order to reduce the performance of the data bus system (6), the first communication unit (1) can send only one of the other messages (300) and only the first one communication unit (1), the relevant confirmation corresponding to the sent message of other messages (300) When it receives the message, it can send the second message of the other messages (300). In the application scenario shown in Figures 6 and 7, the first confirmation message (401) is the first other to the confirmation message (301), second confirmation message (402), second other confirmation message (302) and The third confirmation message (403) corresponds to the third other confirmation message (303). In order to keep the performance of the bus system (6) as low as possible, the first 15 communication unit (1), via data bus system (6) for example first other message (301) can send. In the next step, the second communication unit (2), data bus system (6) It receives the first other message (301) via this. The response to receiving the first other message (301) as the second communication unit (2), second communication unit (2) indicator-15 (381) flag By changing its value from 0 to 1, it advantageously generates the first confirmation message (401). 20 Then the second communication unit (2) sends the first confirmation message (401) to the data bus system (6) sends. Then the first communication unit (1) receives the first confirmation message (401). Message Using identifier-8 (461), the first communication unit (1) sends the first confirmation message (401) to this can be defined in this way and data by taking into account the common data structure of other messages (300). It can read and process area-9 (411). Thus, the first communication unit (1) can read and process the 25 of indicator-20. (481) determines that the flag value is 1. First communication unit (1) preferably, the indicator-20 (481) of the first communication unit (1) Determining that the first other message (301) has been received based on the flag value In this case, another message of the other messages (300), for example the second other message (302) 30 and sends the third other message (303). Similarly, the first communication unit (1), the first communication unit (1) the second confirmation message (402) after receiving and based on the flag value of indicator-21 (482), the second other message (302) After determining that it had been received, it again sent another message from the other messages (300), 35 27 For example, it can send the third other message (303). This situation is the second communication unit (2), second communication unit (2) after receiving the second other message (302) second confirmation message (402) requires sending. The performance of the first communication unit (1) and the data bus system (6) is below the threshold value 5 If it detects that this is the case, the first communication unit will send the messages advantageously (100) sends. Advantageously, the first communication unit (1) sends the first message (101), the second message (102) and sends the third message (103) simultaneously to the bus system (6). Thus connected data (20), from the first communication unit (1) to the second via the data bus system (6). It is possible to send the messages to the communication unit (2) quickly. However, the messages (100) 10 During such a parallel transmission, all of the messages (100) are sent to the second communication unit. (2) does not reach. Depending on which message (100) the second communication unit (2) receives from the messages, the second communication unit (2), as shown in Figure 5, the confirmation message (201) or other confirmation 15 sends its message (202). The second communication unit (2) sends the message (202). The second communication unit (2) is already in If it receives the first message (101) and the second message (102), it will send the confirmation message (201). sends the first message (101), the second message (102) and the third message of the second communication unit (2). If the message (103) is sent, the second communication unit (2) will send the other confirmation message (202) sends. 20 The other confirmation message (202) is structured similarly to the confirmation message (201). Thus, the other confirmation message (202), which data parts of the linked data (20) of the second communication unit (2) It has a data field-5 (212) containing an indicator-8 (272) that it has received. Indicator- 8 (272) can be specified preferably in binary coded form with the help of other confirmation message (202). 25 Unlike the confirmation message (201), indicator-8 (272) is set to another 14. This the situation is the data of the second communication unit (2) the first part (21), the second part (22) and it means that it takes the third part of the data (23). The number fourteen is 21 + 22 + 23 It consists of the sum. If Indicator-8 (272) is equal to fourteen, this situation is second. communication unit (2), first part of the data (21), second part of the data (22) and data 30 This means that he has received the third part (23). The confirmation message (202) is sent to the bus system (6) by the second communication unit (2). Upon sending, the first communication unit (1) can receive the confirmation message (201). The first communication unit (1), after receiving the confirmation message (201), the first communication unit (1) advantageously sends data 35 28 Area-4 (211) processes the value of indicator-7 (271). With indicator-7 (271) having a value of 6. first communication unit (1), second communication unit (2) third part of the data (23) yet It determines that it has not received it. The first communication unit (1) detects this situation, and also in the list. (291) can determine the indicated value by reading it. The first communication unit (1), the second communication After determining that unit (2) did not receive the third part of the data (23), the first communication 5 Unit (1) sends the third message (103) back to the bus system (6). Then the second communication unit (2) receives the third message (103) and the third part of the data (23), by reading and processing data area-3 (113), in particular by storing and linked data (20) In order to reorganize the second part of the data (22) and the first part of the data 10 (21) works by combining. Then the second communication unit (2) advantageously uses the data bus. sends the other confirmation message (202) to the system (6). Then the first communication unit (1) receives the other confirmation message (202) and data field-5 (212) Reads the value of indicator-8 (272). The value of indicator-8 (272) is 15 of the second communication unit (2). If the first communication unit (1) indicates that it has received all parts of the data (20), advantageously, the data (20) successfully to the second communication unit (2) It can generate a signal indicating that it has been sent. The first communication unit (1) is, in particular, 20 of the second communication unit (2) according to the list (291) value. messages (100) containing the relevant parts of the data (20) that it has not yet received It sends its messages. The first communication unit (1) advantageously transmits all the data (20) of the second communication unit (2). until you receive the parts and send the other confirmation message (202) shown in Figure 5 25 He repeats this.
