Agricultural work system

0001The invention relates to an agricultural work system according to the preamble of claim 1 and a method for optimizing operating parameters using an agricultural work system according to the preamble of claim 15.

0002Such an agricultural work system has at least one agricultural work machine, for example also a fleet of agricultural work machines, each of which is coupled to at least one work unit for carrying out or supporting agricultural work. Such an agricultural working machine can be any agricultural working machine that is used to process an agricultural work order, for example a tillage such as plowing, cultivating, harrowing or the like. These include tractors, in particular tractors, but in principle also harvesting machines, in particular forage harvesters, combine harvesters or the like. In the present case, the agricultural work machine designed as a tractor is in the foreground, for example. In addition to built-in work units such as an inclined conveyor, threshing unit, chopping device or the like, work units are also understood to mean attachments such as a plow, cultivator, harrow or the like.

0003In the case of agricultural working machines, for the purpose of optimizing work processes, in particular during a harvesting process, it is known to record and evaluate different operating parameters. The term “operating parameters” is to be understood broadly in the present case. It includes all parameters relevant for the operation of the agricultural working machine and in particular for a work order, in particular machine parameters such as speed or driving speed, work parameters such as the work units used or the agricultural work order carried out and / or environmental parameters such as the soil conditions or the weather. When an operating parameter is mentioned below, its corresponding parameter value is also meant. Corresponding operating parameters are recorded at least partially automatically by means of a driver assistance system of the agricultural working machine, in particular by means of sensors or input devices for operator inputs.

0004In the well-known agricultural work system (<patcit id="pcit0001" dnum="DE102008061252A1"><text>DE 10 2008 061 252 A1</text></patcit>), from which the invention is based, the driver assistance system of an agricultural machine, for example a combine harvester, records a plurality of operating parameters and processes them further on the basis of predetermined regulations (context processing rules) to form a context profile. Such a context profile represents a lot of data that characterize a certain situation or certain environmental or framework conditions. The data are, for example, those relating to the identity, the geographical position and the operating state of the agricultural working machine. For example, the data can state that the agricultural working machine is a combine harvester that is in a certain position at a certain point in time and that drives at a certain speed. Depending on a context profile determined in this way, machine parameters of the agricultural working machine can then be optimized with regard to a specific agricultural work order that is then to be carried out by the working machine. Such an optimization is carried out automatically by the driver assistance system, that is to say without input from the operator. Due to the diverse applications of an agricultural working machine, in particular a tractor, in connection with a large number of different attachments in combination with largely unknown environmental conditions, the known agricultural working system cannot always achieve a satisfactory optimization result.

0005The invention is based on the problem of designing and developing the known agricultural work system in such a way that improved optimization of machine parameters is made possible for the widest possible range of applications.

0006The above problem is solved in an agricultural work system according to the preamble of claim 1 by the features of the characterizing part of claim 1.

0007The proposed agricultural work system has in particular a tractor as an agricultural work machine. In principle, the proposed solution can also be applied to any other agricultural machine, for example a combine harvester or forage harvester. The agricultural working machine has a driver assistance system, which means here and preferably a system that supports the operator in the operation of the same during the execution of an agricultural work order and in the operation on the road or at the agricultural depot. The support can relate to driving and / or steering the agricultural working machine, but also to the evaluation and / or output of operating parameters or corresponding parameter values ​​and in particular also to the control and regulation of the agricultural working machine or individual working units, in particular an attachment , depending on operating parameters.

0008First of all, it is essential to consider that by involving the operator in an optimization process, a better optimization result can be achieved, since it is possible for the operator to quickly and easily evaluate the result of an optimization routine that has been run and, in particular, to immediately decide whether an improvement compared to the state occurred before the optimization routine or not. According to the proposal, after an optimization routine in which one or more operating parameters, in particular machine parameters, or the corresponding parameter values ​​have been changed, an operator feedback in the form of a user-side classification of the optimization result is mandatory. After classification by the operator, the respective changed operating parameters or set of parameters obtained in the course of carrying out the optimization routine are stored in a data pool. Such an operating parameter set in particular also contains a set of corresponding parameter values ​​or Data that characterize a certain situation or certain environmental or framework conditions, for example data that are those relating to the identity (type and / or type), the geographical position and the operating state of the agricultural working machine.

0009Furthermore, it is essential in the proposed solution that the operating parameters or parameter sets stored in the data pool are fed classification-based to an algorithm that is used to generate optimized operating parameters or parameter sets. "Classification-based" means that the respective operating parameter or parameter set or the corresponding parameter values ​​are transmitted to the algorithm depending on the classification result, that is to say depending on the degree of suitability of the parameter or parameter set or the corresponding parameter values ​​for a specific application (for a specific context) determined by the operator. For example, only those operating parameters or parameter sets are transmitted to the algorithm which the operator previously considered to be suitable for the underlying application during the classification. The operator classifies an operating parameter or set of parameters as "suitable", for example when this parameter or set of parameters or the corresponding parameter values ​​an improvement in the result has occurred in the implementation of the underlying agricultural work order.

0010The work result can be assessed on the basis of criteria such as the quality of the machining process, the efficiency of the machining process and the machining performance. The algorithm for generating optimized operating parameters or parameter sets then preferably allows the data in the data pool to be processed in such a way that optimal machine parameters or corresponding values ​​can be derived for new, unknown combinations of work machine and work unit, in particular tractor and attachment . For example, it is conceivable that a parameter set previously classified by the operator for a certain tractor type when plowing under certain environmental conditions is stored in the data pool and that the algorithm optimizes the same or a similar parameter set for another tractor type when plowing or the same tractor type when cultivating under comparable environmental conditions Provides parameter set. In the simplest case, however, the algorithm can also only consist in distinguishing operating parameters or parameter sets classified as suitable from operating parameters or parameter sets classified as unsuitable, and only providing the driver assistance system with the operating parameters or parameter sets classified as suitable. However, this is only conceivable in the event that both the operating parameters or sets of parameters classified as unsuitable are stored in the data pool. In principle, however, it is also conceivable to store from the outset only the operating parameters or parameter sets classified as suitable (crowd-sourced truth data pool) and to discard those classified as unsuitable.

0011With the proposed agricultural work system, it is thus possible to determine a plurality of operating parameters in a context-related manner, for example by means of sensors and / or by the operator himself, including in particular not only machine parameters, but also data which relate to identity (type and / or type), the geographical position and the operating state of the agricultural working machine, including in particular environmental parameters. Furthermore, it is then possible in the context of an optimization routine to adapt at least one operating parameter, in particular machine parameters, with regard to at least one of the criteria "quality", "efficiency" and "performance" by the driver assistance system. The result, that is to say the respectively adapted operating parameter or a parameter set with the respectively adapted operating parameter, is then classified by the operator and the result of the classification is transmitted to the driver assistance system. The driver assistance system then transmits individual, for example only those operating parameters or parameter sets classified as suitable, or in principle all, i.e. also those classified as unsuitable, operating parameters or parameter sets to the data pool, to which the algorithm then generates optimized operating parameters or parameter sets can access for setting the agricultural machine and / or a work unit. The data generated by the algorithm can then also be stored in the data pool. One speaks in this context of so-called "data mining", which means an automatic or semi-automatic evaluation of large amounts of data to determine previously hidden relationships.

0012Claims 2 and 3 define preferred possibilities for the acquisition and output of data by the driver assistance system. Acquisition of data, in particular the plurality of operating parameters or parameter sets, can take place on the one hand via sensors, but on the other hand also by means of operator inputs. It is also conceivable to provide such data via an internal data source, for example an internal memory of the agricultural working machine or an internal memory of the work unit or attachment, or via an external data source (GPS satellite, weather station, Internet, farm computer or the like). An ascertainable operating parameter is in particular also the type and / or the type of the work unit, in particular the attachment. This operating parameter, ie the recognition of the attachment, for example, can also be detected automatically, in particular via RFID, Bluetooth, one or more cameras, M2X communication, ISOBUS, TIM or the like.

0013The driver assistance system can also be configured for natural language acquisition and / or output of data (claim 4).

0014According to the preferred embodiment according to claim 5, a computer for using the algorithm and a data memory for storing the classified operating parameters or parameter sets are provided in the data pool. The data memory or a separate data memory can also be provided for storing the operating parameters or parameter sets generated by the use of the algorithm. The computer and / or the respective data storage device can be part of the agricultural working machine. The computer and / or the respective data memory is particularly preferably part of an external computer network (cloud) of the agricultural work system. The application of the algorithm and / or the storage of the said data is therefore in particular cloud-based.

0015According to claims 6 and 7, data can also be exchanged with other agricultural machines and / or work units. In particular, several agricultural machines can also be used to record operating parameters as described above and to store classified operating parameters in the data pool so that they can be called up. The operating parameters or parameter sets generated by the algorithm can also be made available to other agricultural work machines and / or work units, in particular also to other, for example similar, combinations of agricultural work machine and work unit or attachment. This can be done in particular by means of telemetry with bidirectional communication and / or via an offline optimization on the farm computer and subsequent transmission to the respective agricultural machine and / or by installing a new software update. In particular, optimized recruitment recommendations can be provided for a specific region.

0016Claims 8 and 9 define preferred operating parameters, in particular machine parameters, work parameters and environmental parameters, which can be detected by the driver assistance system and / or used in the machine-side optimization and / or the subsequent classification and / or the subsequent application of the algorithm.

0017Claim 10 defines preferred combinations of operating parameters as operating parameter sets to be classified.

0018Claim 11 defines preferred combinations of operating parameters for which the algorithm generates optimal operating parameters or parameter sets.

0019According to the preferred embodiment according to claim 12, the driver assistance system allows the operator to select an optimization routine by means of which one or more operating parameters can be changed in accordance with a predetermined regulation. The operating parameter or set of parameters obtained by this change is then the one that is classified by the operator, for example, is judged to be suitable or unsuitable for the specific application or the specific context. The optimization routine can in particular optimize the quality of the machining process, the efficiency of the machining process or the machining performance. Accordingly, the operator preferably has the choice between an optimization routine for optimizing the quality of the machining process, an optimization routine for optimizing the efficiency of the machining process and / or an optimization routine for optimizing the machining performance. After selection of an appropriate optimization routine, it can also be provided that the operator is given one or more suggestions by the driver assistance system for at least one operating parameter to be changed, the operator then being able in particular to accept or reject a suggestion (claim 13).

0020Furthermore, the driver assistance system can also be configured to carry out a sensibility assessment of data entries by the operator (claim 14). For example, an operating parameter set that contains the working parameter "plowing work order" in a certain situation, for example immediately after turning, could be inadvertently classified by the operator as suitable, although plowing is not sensible in this situation. The driver assistance system can then interpret the driver's data entry as an incorrect entry and accordingly prevent the classified parameter set from being stored in the data pool.

0021According to a further teaching according to claim 15, which is of independent importance, a method for optimizing operating parameters using an agricultural work system, in particular a proposed agricultural work system, is claimed, with at least one agricultural work machine, in particular a tractor, and with at least one work unit Implementation or support of agricultural work, wherein the agricultural working machine has a driver assistance system for recording, processing and outputting data relating to an agricultural work order. In this case, according to the proposal, a plurality of operating parameters are recorded using the driver assistance system and the operator-side classification of the recorded operating parameters or of operating parameter sets with several different recorded operating parameters is made possible. Furthermore, individual or all classified operating parameters or parameter sets are stored in a data pool and the classification-based operating parameters or parameter sets are transmitted to an algorithm for generating optimized operating parameters or parameter sets for setting the agricultural machine and / or the at least one work unit.

0022The invention is explained in more detail below on the basis of a drawing illustrating only one exemplary embodiment. In the drawing shows<dl id="dl0001"><dt>Fig. 1</dt><dd>is a schematic representation of a proposed agricultural work system with an agricultural machine in the form of a tractor and with an attachment in the form of a plow and</dd><dt>Fig. 2</dt><dd>is a schematic representation of a method for optimizing operating parameters using the agricultural work system according to <figref idref="f0001">Fig. 1</figref>.</dd></dl>

0023In <figref idref="f0001">Fig. 1</figref> is shown how an agricultural work machine 1, here in the form of a tractor, by means of a work unit 2 for carrying out or supporting agricultural work, here an attachment in the form of a plow, carries out an agricultural work order, here a tillage. The agricultural working machine 1 and the working unit 2 or Attachments are part of a proposed agricultural work system for optimizing operating parameters of work machine 1 and / or work unit 2. Agricultural work machine 1 has a driver assistance system 3 for recording, processing and outputting data relating to the agricultural work order, here the tillage. The data here are operating parameters or operating parameter sets with several different operating parameters.

0024The driver assistance system 3 is configured in accordance with the proposal to record a plurality of operating parameters. The operating parameters, which will be explained in more detail below, can be sensed and / or by operator input and / or by calling up from an internal and / or external data source, to name just a few examples. The operating parameters here and preferably represent an operating parameter set with several different operating parameters. One or more operating parameters of the operating parameter set or the corresponding parameter values ​​can be changed during the execution of the work order in order to carry out an optimization. This is preferably carried out as part of an optimization routine selected and started by the operator 4, which will be explained further below.

0025The driver assistance system 3 now allows the operator 4 to carry out a classification of the operating parameter set, which here and preferably contains the changed operating parameter or corresponding parameter value. A classification means an evaluation of the operating parameter set, that is to say the corresponding parameter values, by the operator 4, in which the operator 4 decides whether the work result has been improved or not by the change made to the operating parameter or the operating parameter set. The operator 4 thus decides whether the changed operating parameter or parameter set is suitable or unsuitable for improving the work result. The operator 4 thus classifies the operating parameter or set of parameters in particular as suitable or unsuitable for the specific context, that is to say the specific application. In the classification, the operator 4 can not only decide between "suitable" and "unsuitable" according to a particular embodiment, but can also carry out one or more gradations in between.

0026Here and preferably, the operating parameter set also contains, in addition to one or more machine parameters, one or more working and environmental parameters that specify the specific context in more detail, for example the type of agricultural machinery and / or attachment type, weather and / or soil conditions or the like during the execution of the agricultural work order . The classification by the operator can thus be used to make a statement about the suitability of certain machine parameters in combination with certain working and / or environmental parameters (for example type of agricultural machinery and / or attachment type, weather and / or soil conditions).

0027The proposed agricultural work system also provides a data pool in which previously classified operating parameters or here and preferably operating parameter sets with different operating parameters are stored and can be called up. Such a data pool is, for example, a croud-sourced truth data pool, in which, from different sources, that is to say from different driver assistance systems 3, only operational parameter sets classified as suitable are stored.

0028The operating parameters, or here the operating parameter sets, are then transmitted according to the proposal based on classification, that is to say depending on the classification result (for example result "suitable" or "unsuitable"), an algorithm which context-optimized operating parameters or parameter sets for setting an agricultural machine 1 and / or a work unit 2 generated. The data generated by the algorithm are then operating parameters or sets of parameters that the agricultural working machine 1 and / or the working unit 2 and / or another agricultural working machine 1 'or another working unit 2' can use in order to, in the same or similar context, that means, for example, in the same or similar weather and / or soil conditions, to be able to be operated with optimized machine parameters. The algorithm can thus be used to determine context-related optimal settings, which in particular also for future uses of one and the same agricultural work machine 1 and / or one and the same work unit 2 or also for use of other, in particular similar, combinations of agricultural work machine 1 'and work unit 2 'can be used to achieve an optimal work result.

0029To record data, in particular the plurality of operating parameters or sets of parameters, the driver assistance system 3 is coupled here and preferably to one or more sensors 5 of the agricultural working machine 1 and / or to one or more sensors 6 of the working unit 2. To acquire the data, a coupling with an internal data source of the agricultural working machine 1 and / or the working unit 2 and / or with an external data source such as a GPS satellite, a weather station, the Internet or the farm computer or the like is also conceivable. For this purpose, the driver assistance system 3 can also be coupled, as here, to at least one input device 7 for user-side data input, in particular a keyboard, a touchscreen 8 and / or a microphone 9. The input device 7 can be part of the agricultural working machine 1, the working unit 2 and / or a mobile device. In particular, machine parameters and possibly at least some working parameters and / or environmental parameters can be detected via the respective sensor 5, 6. Via the input device 7, the operator 4 can enter further operating parameters, in particular machine, work and / or environmental parameters, such as agricultural machine and / or attachment type and / or type, which are not automatically detectable and transmit them to the driver assistance system 3.

0030As already described above, the driver assistance system 3 allows an operator-side classification of operating parameters or, in this case, a respective set of operating parameters with a number of different operating parameters. For the purpose of classification, the driver assistance system 3 can here and preferably output data to the operator 4, for example specific operating parameters or parameter sets to be classified by the operator, or merely a query as to how he assesses the changed situation. The output of data to the operator, for example the output of an operating parameter set or the output of a query to the operator 4, takes place in particular via an output device 10 coupled to the driver assistance system 3, in particular a display, a touchscreen 8 and / or a loudspeaker 11.

0031The driver assistance system 3 is particularly preferably suitable for the natural language acquisition of data transmitted by the operator and / or for the natural language output of data to the operator 4.

0032Here and preferably, a computer 12 for applying the algorithm and a data memory 13 for storing the classified operating parameters or parameter sets are provided in the data pool. The data memory 13 is used here and preferably also for storing the optimized operating parameters or parameter sets generated by using the algorithm for the setting of an agricultural working machine 1 and / or at least one working unit 2. The computer 12 and / or the respective data memory 13 can be part of the agricultural work machine 1, but here and preferably are part of an external computer network or a cloud 14 of the agricultural work system.

0033A cloud 14 with computer 12 and data storage 13 is in <figref idref="f0002">Fig. 2</figref> represented symbolically. Is also shown symbolically in<figref idref="f0002">Fig. 2</figref>that other agricultural machines and / or work units can also retrieve the operating parameters or parameter sets optimized by means of the algorithm from the cloud 14. In<figref idref="f0002">Fig. 2</figref> Different combinations 1 ', 2' of other agricultural machines and work units are symbolically represented by rectangles. The illustrated combinations 1 ′, 2 ′, which use the data from the cloud 14, can have the same type of agricultural machinery and / or attachment and / or the same type of agricultural machinery and / or attachment as that based on<figref idref="f0001">Fig. 1</figref> described combination of agricultural machine 1 and work unit 2, which have provided the data that the algorithm has used.

0034In principle, it is also conceivable to transmit data from different driver assistance systems of different combinations of agricultural work machine 1 and work unit 2 to the algorithm. Thus, it is preferably provided that a plurality of agricultural working machines 1 of the agricultural working system, in particular the same fleet, each have a driver assistance system 3 for recording, processing and outputting data relating to an agricultural work order, which is configured to record a plurality of operating parameters and to enable operator-side classification of the recorded operating parameters or of operating parameter sets with several different recorded operating parameters, wherein individual or all classified operating parameters or parameter sets are stored in the data pool and are transmitted based on classification to an algorithm for generating optimized operating parameters or parameter sets for the setting of an agricultural working machine 1 and / or at least one working unit 2.

0035The operating parameters here are in particular machine parameters, working parameters and / or environmental parameters.

0036The respective machine parameter is selected in particular from the group comprising the driving speed, the fuel consumption, the output drive power, the output drive torque, the speed of the drive shaft, the engine pressure, the shift speed, parameters of the shift characteristics, parameters of the slip control, parameters of the traction control, parameters of the full load control , the air pressure and / or tire type of the front and / or rear pair of tires, the weight of a front and / or rear ballast device, parameters of the front and / or rear linkage, the top link position, parameters of the traction cylinders, parameters of the hydraulic valve setting, the hollow disc position, the pull point, the pressing pressure, the contact pressure, parameters of the conditioner gap and / or parameters of the Steering system and changes to the settings of the respective machine parameters.

0037The respective work parameter is in particular selected from the group comprising an agricultural work order, the type and / or type of agricultural work machine, the type and / or type of the respective work unit, in particular. Attachment, the mechanical, hydraulic and / or electrical connection of the respective work unit to the agricultural machine, the machine settings from ISOBUS, the power requirement of the respective work unit, the working depth and / or width of the respective work unit, the area consumption and / or the area performance.

0038The respective environmental parameter is selected in particular from the group comprising the terrain profile of the field and / or the current lane, the size of the field, the current weather data, the GPS position data, the current crop type, the current population variety, the current crop quality of the field and / or the current lane (moisture, density, height), the current soil condition of the field and / or the current lane (moisture, density, soil type, soil condition), and / or the history of the field and / or the current lane, in particular the or a previous crop, population type, crop quality and / or soil conditions. So not only field-related but also track-related data can be used.

0039The parameter sets to be classified by the operator are, in particular, combinations of one or more machine parameters, in particular one or more of the machine parameters mentioned, and / or one or more work parameters, in particular one or more of the work parameters mentioned, and / or one or more environmental parameters, in particular one or more of the environmental parameters mentioned.

0040Here and preferably, the algorithm generates the optimized operating parameters or parameter sets for certain combinations of operating parameters, in particular for certain combinations of an agricultural working machine 1, a work unit 2 and one or more environmental parameters, in particular one or more of the environmental parameters mentioned.

0041The driver assistance system 3 of the proposed agricultural work system is configured here and preferably so that the operator 4 can select an optimization routine, in particular via a selection menu displayed and / or acoustically transmitted to him. In the optimization routine, at least one predetermined operating parameter, preferably at least one machine parameter, in particular at least one of the aforementioned machine parameters, is changed according to a predetermined rule. Based on the at least one changed operating parameter, the driver assistance system 3 enables the operator 4, as previously explained, to classify the operating parameter or here a parameter set that contains this operating parameter and one or more other operating parameters.

0042Here and preferably the operator 4 can select the optimization routine from the group comprising the optimization of the quality of the machining process, the optimization of the efficiency of the machining process and the optimization of the machining performance.

0043Criteria for the quality of the processing process are, for example, the plow pattern, the spread pattern, the swath or the like, or also soil damage such as soil compaction and / or lubrication. Criteria for the efficiency of the processing process are, for example, the fuel consumption based on the driving speed of the agricultural working machine 1, the fuel consumption per unit area based on the driving speed of the agricultural working machine 1, the fuel consumption based on the time required to carry out an agricultural work order or the fuel consumption per unit area based on the time required to carry out an agricultural work order. Criteria for the processing performance are, for example, the processed area per unit of time or the processed area per unit of time based on the driving speed of the agricultural working machine 1.

0044Here and preferably, the driver assistance system 3 is further configured to provide the operator 4 with one or more suggestions for the at least one operating parameter to be changed after an appropriate optimization routine has been selected by the operator. The operator 4 then has the option of accepting and / or rejecting the proposal or at least one of the proposals. For example, the operator 4 is shown a list with several suggestions, which is sorted in particular according to a certain order, for example according to the degree of the expected impact on the quality of the machining process and / or on the efficiency of the machining process and / or on the machining performance. It is also conceivable that only one suggestion is displayed to the operator 4, whereby a new proposal is output by the operator 4 after the operator has rejected it. Here too, a specific order in which the suggestions are issued can be provided, which is also based, for example, on the degree of the expected impact on the quality of the machining process and / or on the efficiency of the machining process and / or on the machining performance.

0045Now that a suggestion has been accepted by the operator, the driver assistance system 3 executes here and preferably the optimization routine in such a way that at least one changed operating parameter, in particular machine parameters, or an operating parameter set with at least one changed operating parameter is generated as a result, whereupon the operator 4 then classifies the changed operating parameters or can carry out parameter set by assessing the quality of the machining process, the efficiency of the machining process or the machining performance in relation to the state before the operating parameter or parameter set was changed. For assessment, the driver assistance system 3, in particular acoustically and / or visually, can ask the operator 4, for example, whether an improvement in the quality of the machining process or the efficiency of the machining process or the machining performance can be determined. The operator 4 can then answer the question, in particular by voice input, touch screen input or key input, for example with “yes” or “no”.

0046Finally, the driver assistance system 3 can be configured to carry out a sensibility assessment of data inputs by the operator 4. For example, operator 4 may make an incorrect entry that would lead to incorrect classification. The driver assistance system 3 can then verify according to predetermined regulations whether the input makes sense or not. In this way it can be prevented that incorrectly classified operating parameters or parameter sets are stored in the data pool and transmitted to the algorithm.

0047An exemplary sequence of a method for optimizing operating parameters using a proposed agricultural work system is shown <figref idref="f0002">Fig. 2</figref>.

0048The driver assistance system 3 detects different operating parameters in various ways, for example via one or more sensors 5 of the agricultural working machine 1 and / or via one or more sensors 6 of the respective working unit 2. There is also the possibility of using a sensor fusion in which data from different of sensors 5, 6 can be linked in order to thereby obtain better quality information. Furthermore, according to<figref idref="f0002">Fig. 2</figref> provide the driver assistance system 3 with a touch screen 8 and / or a microphone 9 for data input by the operator. To output data to the operator 4, the driver assistance system 3 is provided here and preferably with a loudspeaker 11 and the touchscreen 8.

0049In the exemplary embodiment of the proposed method shown here, the operator 4 can start an optimization routine (arrow 15), whereupon the driver assistance system 3 generates a list with suggestions in the form of changeable machine parameters (symbol 16).

0050The list with the suggestions generated is then output to operator 4, for example in natural language (arrow 17).

0051The operator 4 then selects a proposal from the list (arrow 18), whereupon the driver assistance system 3 generates at least one changed machine parameter (symbol 19) and transmits a corresponding control command to the agricultural working machine 1 and / or the working unit 2 (arrow 20).

0052The agricultural working machine 1 and / or the working unit 2 then changes the parameter settings accordingly. It is also conceivable, in particular if no automatically adjustable actuator is provided, that the driver himself carries out the change in the parameter setting, for example sets a different top link position by means of a different bolting of the top link. This can change the work result, for example the quality of the machining process, the efficiency of the machining process or the machining performance.

0053Optionally, the changed machine parameter (s) can also be determined via sensors 5, 6 of the agricultural working machine 1 and / or the working unit 2 and transmitted to the driver assistance system 3 (arrow 21).

0054After the at least one machine parameter has been changed, the driver assistance system 3 generates a query (symbol 22) which is transmitted to the operator 4, possibly together with the display of the changed machine parameter or an operating parameter set with the changed machine parameter (arrow 23).

0055The operator 4 then himself carries out a decision-making process based on an assessment of the overall situation (symbol 24) and transmits the result to the driver assistance system (arrow 25) by corresponding input, for example via the touchscreen 8 or the microphone 9.

0056The driver assistance system 3 then prepares the data, which includes, for example, linking the respectively changed machine parameter with other operating parameters, for example environmental parameters (symbol 26). In this case, the driver assistance system 3 can also carry out a sensibility assessment of data input by the operator.

0057The processed data is then transferred to the cloud 14, which optimizes a computer 12 for using an algorithm for generating optimized operating parameters or parameter sets and a data memory 13 for storing the classified operating parameters or parameter sets and possibly for storing the ones generated by using the algorithm Has operating parameters or sets of parameters (arrow 27).

0058The optimized operating parameters or parameter sets generated by the algorithm can finally be transmitted to different combinations 1 ', 2' of agricultural working machine 1 and working unit 2 and used by them as operating parameters or parameter sets optimized for the respective application, preferably also the different ones Combinations 1 ', 2 'of agricultural work machine 1 and work unit 2 can transmit their own data to the cloud 14, in particular in the manner described above, optimized operating parameters or parameter sets generated by an appropriate algorithm (arrow 28).
